1 00:00:05,780 --> 00:00:10,880 A what's up everyone Mark Price your depth slopes Stockholm and we're making great progress with our 2 00:00:11,320 --> 00:00:21,640 app and what we've done so far as we've made it so you can see three objects three 3-D objects in a 3 00:00:21,950 --> 00:00:24,610 View Controller in a scene view they're rotating. 4 00:00:24,640 --> 00:00:28,960 And when you tap it it prints the name so we know which one is being tapped and we're actually passing 5 00:00:28,960 --> 00:00:31,800 that name back to a ramp place or visi. 6 00:00:32,050 --> 00:00:39,070 And what we want to do here in the on ramp selected OK is what we want to do is we want to make it so 7 00:00:43,570 --> 00:00:47,270 it stores the name of the object that we're going to be placing. 8 00:00:47,500 --> 00:00:48,030 OK. 9 00:00:48,190 --> 00:00:53,110 And then when we need to detect when the screen is tapped again so we can actually place it in the appropriate 10 00:00:53,110 --> 00:00:53,500 spot. 11 00:00:53,510 --> 00:00:55,000 But on this screen this time. 12 00:00:55,060 --> 00:01:02,200 So we're going to need a variable to store the name of the ramps so let's go up to the top here and 13 00:01:02,200 --> 00:01:09,370 create a new variable here var and we're going to say selected ramp is going to be of type string and 14 00:01:09,370 --> 00:01:14,560 it isn't optional because it may at first there's nothing there. 15 00:01:14,740 --> 00:01:16,280 So var selected ramp. 16 00:01:16,960 --> 00:01:23,050 And what we're going to do is say selected ramp ramp name. 17 00:01:24,020 --> 00:01:25,160 That looks good to me. 18 00:01:25,450 --> 00:01:32,350 And then we just probably need to implement the touches begin to override function here. 19 00:01:32,350 --> 00:01:39,580 So let's put that let's put it here just for fun or to say touches began. 20 00:01:40,000 --> 00:01:44,950 And anytime a touch starts it'll call this code here which is what we want and then let's just write 21 00:01:44,950 --> 00:01:51,310 some code to detect the touch get it's the position of the touch and then we need to place a 3D object 22 00:01:51,400 --> 00:01:52,990 at the point that's being touched. 23 00:01:52,990 --> 00:01:56,760 OK so it detects a touch figures out where on the screen it's happening. 24 00:01:57,010 --> 00:02:06,260 And then we can place an object there and when detecting a touch on the on the view here this scene 25 00:02:06,460 --> 00:02:11,140 view you do do it a little bit differently than we just did it in the regular scene kit view. 26 00:02:11,140 --> 00:02:14,070 So let's go ahead and get started here. 27 00:02:14,140 --> 00:02:18,500 So guard let touch equals touch up first. 28 00:02:18,730 --> 00:02:25,650 So we're guarding against there not being a touch or. 29 00:02:26,350 --> 00:02:26,610 Yeah. 30 00:02:26,620 --> 00:02:30,510 We're guarding against they're not being attacked so we're grabbing touches done first. 31 00:02:30,660 --> 00:02:31,200 OK. 32 00:02:32,920 --> 00:02:37,820 And then next thing is let results equals scene view. 33 00:02:37,900 --> 00:02:44,020 Hit test we are using the similar hit test because it is using the same functionality under the hood 34 00:02:44,020 --> 00:02:44,940 that we just did. 35 00:02:44,980 --> 00:02:46,080 So hit test. 36 00:02:46,450 --> 00:02:50,990 And in this case we're going to type touch dot location for the point. 37 00:02:51,660 --> 00:02:52,200 OK. 38 00:02:52,520 --> 00:02:57,380 You didn't touch that location. 39 00:02:57,680 --> 00:02:58,410 OK. 40 00:02:59,080 --> 00:03:01,570 Seen you. 41 00:03:01,750 --> 00:03:02,250 There you go. 42 00:03:02,270 --> 00:03:06,820 OK we're calling the touch stultification function in Seamew I got confused by the syntax here. 43 00:03:06,850 --> 00:03:13,650 And then lastly we have the options and what we want in this case is a feature point. 44 00:03:14,400 --> 00:03:15,730 OK. 45 00:03:17,200 --> 00:03:19,760 We'll let this stop airing out us. 46 00:03:19,780 --> 00:03:22,480 Come on now. 47 00:03:22,540 --> 00:03:23,940 What did I spell wrong. 48 00:03:25,250 --> 00:03:26,060 Feature point. 49 00:03:26,060 --> 00:03:27,370 This looks good to me. 50 00:03:30,180 --> 00:03:32,980 Now closing closing not. 51 00:03:32,980 --> 00:03:33,580 Correct. 52 00:03:33,580 --> 00:03:34,660 What does it yelling at me for 53 00:03:37,840 --> 00:03:41,200 does not like it at all what is going on. 54 00:03:41,200 --> 00:03:47,050 Feature point feature point types Oh I called the wrong I called the wrong 55 00:03:51,130 --> 00:03:54,570 the wrong thing it's types. 56 00:03:54,570 --> 00:03:55,040 OK. 57 00:03:55,260 --> 00:04:00,350 And what I wanted to do was show you the feature point here. 58 00:04:00,600 --> 00:04:05,070 So result type result type from intersecting the nearest future point. 59 00:04:05,070 --> 00:04:06,540 This is in a market. 60 00:04:06,540 --> 00:04:10,800 And so basically remember it detects the floors in the walls and everything. 61 00:04:10,800 --> 00:04:16,500 And so when you tap it's using it's very complex under the hood math to figure out where on the wall 62 00:04:16,500 --> 00:04:18,780 or the floor that you tap and get the actual distance to stuff. 63 00:04:18,780 --> 00:04:20,250 Very cool stuff. 64 00:04:20,370 --> 00:04:23,700 Very complex stuff in there doing that for us and so that's what future point does. 65 00:04:23,700 --> 00:04:27,740 You can also look at some of the other things that they have here as well to see what they do. 66 00:04:27,780 --> 00:04:31,640 I will not be explaining them because we are using the feature point. 67 00:04:31,910 --> 00:04:36,330 It's just going to get the nearest intersection in years in your room or you're outside or wherever 68 00:04:36,450 --> 00:04:37,230 it's detecting. 69 00:04:37,230 --> 00:04:38,010 OK. 70 00:04:38,550 --> 00:04:40,060 Guard let hit. 71 00:04:40,070 --> 00:04:44,900 Feature equals results that last else return. 72 00:04:45,150 --> 00:04:47,730 So now we're getting the results of a tap. 73 00:04:47,730 --> 00:04:50,040 So here's something really important. 74 00:04:50,040 --> 00:04:56,700 Understand sometimes a market can't find angles if your room is too dark it can't find an angle if it's 75 00:04:56,700 --> 00:04:58,200 too dark anywhere or too fuzzy. 76 00:04:58,200 --> 00:05:02,700 Or let's say you're just looking at the ground but it can't see walls or can't see a car in the distance 77 00:05:02,700 --> 00:05:05,270 or something that can give it some context. 78 00:05:05,490 --> 00:05:07,590 You may get nothing here and it will return. 79 00:05:07,590 --> 00:05:13,280 So if you're in our app and other apps let's say especially in our app if you're tapping and like nothing's 80 00:05:13,290 --> 00:05:15,490 happening it's because we're hitting this returns same. 81 00:05:15,510 --> 00:05:19,240 And the reason why is because it's not finding the feature on the ground. 82 00:05:19,350 --> 00:05:24,240 But you'll notice when you move closer to something where there's two objects it works. 83 00:05:24,240 --> 00:05:30,000 And so it needs it needs context in order to be able to place the object. 84 00:05:30,030 --> 00:05:30,750 OK. 85 00:05:31,500 --> 00:05:33,780 Hit feature results that last else return. 86 00:05:33,780 --> 00:05:39,690 So to make sure that we actually find an object when when it's being tapped it finds that reference 87 00:05:39,690 --> 00:05:39,980 point. 88 00:05:39,990 --> 00:05:48,210 OK let it transform equals as seen matrix for came. 89 00:05:48,430 --> 00:05:55,510 And what we're going to do is we're just going to pass in the the world transform the hit feature so 90 00:05:55,510 --> 00:05:58,900 hit feature world transform. 91 00:05:59,360 --> 00:06:00,020 OK. 92 00:06:00,250 --> 00:06:02,950 So we're grabbing the transform from the from the tap. 93 00:06:02,950 --> 00:06:03,370 OK. 94 00:06:03,370 --> 00:06:07,810 Meaning remember if there was nothing we're returning we're not even getting here otherwise there was 95 00:06:07,810 --> 00:06:14,380 something and we are going to take it and get the transform for it so we can actually use it and place 96 00:06:14,380 --> 00:06:15,190 a 3-D object. 97 00:06:15,190 --> 00:06:15,890 OK. 98 00:06:16,360 --> 00:06:22,360 Let me get position equals s.c and vector 3 make. 99 00:06:22,430 --> 00:06:24,040 We're going to say hit transform 100 00:06:26,650 --> 00:06:28,830 em for one hit. 101 00:06:28,830 --> 00:06:41,630 Transform em for two and get transformed for three and a. 102 00:06:41,650 --> 00:06:42,330 Thank you. 103 00:06:43,870 --> 00:06:45,240 Make sure there's no errors here. 104 00:06:47,960 --> 00:06:48,430 OK. 105 00:06:48,600 --> 00:06:49,640 And you're probably wondering. 106 00:06:49,640 --> 00:06:53,760 Hey Mark how do you know what for one and for two and three is. 107 00:06:53,760 --> 00:07:00,330 Well if we can click this here OK we're going to be sadly disappointed because there's not a whole lot 108 00:07:00,330 --> 00:07:06,060 of information on what these are but what's happening is this SDN matrix for storing data in regards 109 00:07:06,060 --> 00:07:10,370 to the transform from this from this hit test here. 110 00:07:10,470 --> 00:07:14,030 And because Apple documentation and apple example say so. 111 00:07:14,070 --> 00:07:20,700 I know that for one and for two and for three are the translation or the positioning and floats that 112 00:07:20,700 --> 00:07:21,980 you need to access. 113 00:07:22,080 --> 00:07:25,280 Outside of that I honestly I'm not sure how you would figure it out. 114 00:07:25,280 --> 00:07:30,330 There's no documentation on there but in the Apple documentation they do reference these three points 115 00:07:30,390 --> 00:07:33,000 as translation or position. 116 00:07:33,000 --> 00:07:37,590 And so that's what we're grabbing here of the hit position which is why you got to read Apple documentation 117 00:07:38,610 --> 00:07:43,500 usually it's very safe to do things the way that they do it and their example projects. 118 00:07:43,500 --> 00:07:50,900 So what we've done here is we have we've looked at we've done a hit test so we grabbed the touch. 119 00:07:50,900 --> 00:07:53,980 We've done a hit test on that touch on to get the results. 120 00:07:53,990 --> 00:07:55,110 Now if there was a tap. 121 00:07:55,220 --> 00:07:55,730 OK. 122 00:07:55,880 --> 00:07:59,870 What we're doing is we're grabbing the world transform of that touch. 123 00:07:59,990 --> 00:08:01,310 OK. 124 00:08:01,310 --> 00:08:08,900 So the hit feature is going to it's going to find the horizontal and vertical position of where you 125 00:08:08,900 --> 00:08:09,430 tapped. 126 00:08:09,440 --> 00:08:13,050 And again you know make sure you tap on something that has context. 127 00:08:13,100 --> 00:08:14,990 We're grabbing the world transform for that. 128 00:08:15,050 --> 00:08:19,900 And then we're creating a positioning vector 3 here of the actual position in 3D accordant space so 129 00:08:19,900 --> 00:08:21,220 we can place an object. 130 00:08:21,430 --> 00:08:23,830 And you don't have to understand this completely in order to use it. 131 00:08:23,990 --> 00:08:30,080 But this is typically the process you'll follow when placing objects in a market in a 3D space very 132 00:08:30,080 --> 00:08:31,400 similar to this here. 133 00:08:31,720 --> 00:08:35,790 OK the next step is to actually place an object on the screen. 134 00:08:36,110 --> 00:08:37,090 So how do we do that. 135 00:08:37,090 --> 00:08:41,240 Well we're going to have to create the node like we did in the in the picker with just three objects 136 00:08:41,270 --> 00:08:43,580 and then place it at the position. 137 00:08:43,610 --> 00:08:48,510 So down here we can create a function called Place ramp. 138 00:08:48,730 --> 00:08:53,850 We're going to pass in the position of S in vector 3 like so. 139 00:08:54,440 --> 00:08:56,200 And then let's call this function up here. 140 00:08:56,330 --> 00:08:58,720 So we're going to say placed ramp. 141 00:08:58,730 --> 00:09:06,570 And let's just pass in the hit position like so and then what do we need to do here we need to actually 142 00:09:06,570 --> 00:09:08,230 get those ramps again. 143 00:09:08,380 --> 00:09:14,690 So see here yeah we've got time let's do it so over here and our rent picker. 144 00:09:15,000 --> 00:09:20,670 OK we've got these We've got these three objects here as you can see these three 3-D objects and we 145 00:09:20,670 --> 00:09:27,090 need to be able to have similar code so what I want to do is I want to refactor to make this more more 146 00:09:27,090 --> 00:09:27,900 reusable. 147 00:09:28,000 --> 00:09:34,640 OK so we're going to go to our project here and new group and we're going to call this model. 148 00:09:35,520 --> 00:09:39,200 And inside the model folder we're going to add a new file. 149 00:09:39,600 --> 00:09:40,300 OK. 150 00:09:40,620 --> 00:09:44,580 And what we want to do is just make this a swift file and make empty right now. 151 00:09:44,910 --> 00:09:52,040 And let's call this ramp and we're going to import scene kit like so. 152 00:09:52,050 --> 00:09:58,500 Class is going to be ramp and then what we're going to do is create a series of functions static functions 153 00:09:58,530 --> 00:10:01,670 that we can just call to get the things that we want to get. 154 00:10:01,720 --> 00:10:11,140 So what we can do is we can say a class phunk get pipe for getting the half pipe and it's going to return 155 00:10:11,550 --> 00:10:14,390 an SDN node like so. 156 00:10:14,470 --> 00:10:20,350 And then what we can do is we can go to a ramp picker code and we can copy some of the stuff here. 157 00:10:20,350 --> 00:10:28,330 So just take this copy the pipe go back to our ramp paste it here will change it to let's this time 158 00:10:29,500 --> 00:10:40,660 and let But instead of adding to the root note we'll just return the note itself like so very good. 159 00:10:40,850 --> 00:10:50,900 And then we'll create one for will create two others for class phunk get pyramid CNO and then world 160 00:10:51,230 --> 00:10:58,200 class phunk get quarter for the quarter pipe as seen. 161 00:10:59,170 --> 00:11:00,160 Like so. 162 00:11:00,410 --> 00:11:05,450 And let me point out here where we're specifically grabbing objects. 163 00:11:05,480 --> 00:11:06,090 OK. 164 00:11:06,130 --> 00:11:09,660 And placing them with a certain scale and things because we want them to look a certain way. 165 00:11:09,860 --> 00:11:14,900 If you're actually building a game or there's lots of things going on objects being instantiated coming 166 00:11:14,900 --> 00:11:20,390 from different places of course you wouldn't manually like place individual objects here because you 167 00:11:20,390 --> 00:11:24,030 would build a manage it all by say scene kids. 168 00:11:24,110 --> 00:11:26,630 I think it's pretty rough to work with I would not make a game and sink it. 169 00:11:26,660 --> 00:11:29,540 If you want to make full scale game do it in unity 3D. 170 00:11:29,720 --> 00:11:31,320 Absolutely for sure. 171 00:11:31,550 --> 00:11:35,480 And we do have courses on that an amazing course actually. 172 00:11:35,480 --> 00:11:36,800 And it's so easy to use. 173 00:11:36,800 --> 00:11:40,550 And so if you really are serious about working with a market and making something immersive where you 174 00:11:40,550 --> 00:11:45,070 don't need the standard controls from Iowa has worked with unity. 175 00:11:45,080 --> 00:11:46,640 It's absolutely fantastic. 176 00:11:46,640 --> 00:11:47,210 OK. 177 00:11:47,480 --> 00:11:52,700 And so Node 1 action rotate we're going to take this out because we don't want the we don't want to 178 00:11:52,700 --> 00:11:58,730 run the rotation on the on the objects that are in the in the market. 179 00:11:58,880 --> 00:12:00,430 So I want to take that out there. 180 00:12:00,560 --> 00:12:09,670 And so there's our get pipe Let's go back to our picker and let's go ahead and copy this one so ramp 181 00:12:10,760 --> 00:12:11,550 ramp. 182 00:12:11,570 --> 00:12:12,910 So this is the pyramid right. 183 00:12:13,000 --> 00:12:13,350 Yep. 184 00:12:13,610 --> 00:12:15,130 This is great. 185 00:12:15,480 --> 00:12:19,630 Let here and here we're just we're ready factory making a little more better. 186 00:12:19,640 --> 00:12:24,270 It's not a huge improvement but it's it's a little improvement and that's good enough for me. 187 00:12:24,350 --> 00:12:29,400 Return node like so. 188 00:12:29,630 --> 00:12:39,890 And let's go over here again to our quarter pipe and do the same thing. 189 00:12:39,990 --> 00:12:49,290 Good quarter and we're going to say let and let us get rid of the action and let's get rid of the root 190 00:12:49,290 --> 00:12:57,990 node thingy and let's return the node like so and then what we can do is go back to our ramp picker 191 00:12:58,230 --> 00:13:03,720 and we can refactor this here which is nice and you know what let's actually let's put this in a function 192 00:13:03,720 --> 00:13:06,890 as well to rotate action. 193 00:13:07,020 --> 00:13:10,070 Let's put it in there so let's go back to a ramp actually. 194 00:13:10,160 --> 00:13:10,550 That's great. 195 00:13:10,540 --> 00:13:22,610 Another class function class phunk start to make this bigger for you here we go start rotation pass 196 00:13:22,630 --> 00:13:25,950 in a node and we're just going to rotate it as C.A.. 197 00:13:26,640 --> 00:13:35,460 All we have to do is take those lines of code from the ramp picker namely the rotation like so place 198 00:13:35,460 --> 00:13:44,420 it here and then let's grab the run action like so and place it in the ramp as well. 199 00:13:45,080 --> 00:13:54,340 So I just do something silly and this is my go here it goes in the ramp. 200 00:13:54,340 --> 00:13:55,350 There we go. 201 00:13:55,840 --> 00:13:58,840 And then back to the ramp put the ramp picker. 202 00:13:58,840 --> 00:14:04,790 We will do the no run action command see it over here in our ramp. 203 00:14:04,990 --> 00:14:10,400 OK so we're just taking this note that was passed in and we're just running an action on it. 204 00:14:10,600 --> 00:14:18,670 So now what we can do now that this is all cleaned up we can make our code it's a cleanup I'll be here 205 00:14:18,670 --> 00:14:21,000 and now we can make our code more cleanup and the rent picker. 206 00:14:21,120 --> 00:14:26,010 So what I want to do is I want to just delete all this stuff here. 207 00:14:28,050 --> 00:14:28,820 OK. 208 00:14:29,060 --> 00:14:30,580 And this too. 209 00:14:31,180 --> 00:14:38,150 And it should be pretty easy to say let pipe equals frap that get pipe and then we're going to say ramp 210 00:14:38,170 --> 00:14:43,750 does start rotation and will pass in the pipe to start rotating it and then we'll say seen that root 211 00:14:43,750 --> 00:14:47,900 node add child and we're just going to say pipe. 212 00:14:48,220 --> 00:14:58,300 No big deal like so we'll do the same thing for the other one so let here mid equals ramp get pyramid 213 00:14:59,620 --> 00:15:08,770 ramp start rotation and we were going to say pyramid and then seen that root node add child node and 214 00:15:08,770 --> 00:15:16,900 we're going to say pyramid pyramid and one more let quarter pipe or quarter equals ramp get quarter 215 00:15:19,170 --> 00:15:27,660 and we're to say ramp dot start rotation quarter and then we're going to say seen out root node add 216 00:15:27,660 --> 00:15:34,530 child node and we're going to say quarter. 217 00:15:35,100 --> 00:15:40,080 So let's make sure that our code is still working meaning the ramps are still there same positions and 218 00:15:40,080 --> 00:15:41,740 that they are rotating. 219 00:15:41,760 --> 00:15:50,160 So it's run the app and see secret button and they are rotating sure enough they're rotating and this 220 00:15:50,160 --> 00:15:53,640 looks really really good. 221 00:15:53,640 --> 00:15:53,910 Cool. 222 00:15:53,910 --> 00:15:55,800 So what we've done is we've just refactored our code. 223 00:15:55,800 --> 00:15:56,720 We've cleaned it up. 224 00:15:56,760 --> 00:15:58,170 We've made it more reusable. 225 00:15:58,210 --> 00:16:04,860 Now what we can do to stop this is we can go into our ramp placer which I'm already here and now we 226 00:16:04,860 --> 00:16:06,800 can actually place the ramp. 227 00:16:06,810 --> 00:16:14,030 We can we can use that those same functions that we just used and place the ramp somewhere on the screen. 228 00:16:14,140 --> 00:16:14,820 OK. 229 00:16:14,970 --> 00:16:17,420 So it should be as simple as LET. 230 00:16:17,460 --> 00:16:21,030 Ramp equals Well shoot. 231 00:16:21,030 --> 00:16:22,430 We don't know it. 232 00:16:22,770 --> 00:16:25,740 We don't know which ramp to ramp to use. 233 00:16:25,740 --> 00:16:30,150 We know the selected name of a ramp but we don't know which one to use. 234 00:16:30,150 --> 00:16:37,220 So we probably need one more function in our ramp here so we can actually just determine which ramp 235 00:16:37,220 --> 00:16:37,850 to get. 236 00:16:37,850 --> 00:16:39,290 So I'll put up here at the top. 237 00:16:39,290 --> 00:16:46,680 A new function and we're going to say class phunk get ramp for name. 238 00:16:46,730 --> 00:16:47,410 All right. 239 00:16:47,450 --> 00:16:52,420 Or to say ramp name of type string. 240 00:16:52,670 --> 00:16:53,130 Perfect. 241 00:16:53,150 --> 00:16:56,050 And we're going to return an LCN node. 242 00:16:56,540 --> 00:16:58,540 We're simply going to switch the ramp name. 243 00:16:58,620 --> 00:16:59,330 That's all. 244 00:16:59,330 --> 00:16:59,950 All right. 245 00:17:00,110 --> 00:17:02,060 No big deal. 246 00:17:02,150 --> 00:17:10,040 So if the case is pipe Let's go ahead and just return the ramp that get pipe. 247 00:17:10,040 --> 00:17:10,970 All right. 248 00:17:10,970 --> 00:17:18,950 And then if the case is quarter well its return ramp get quarter. 249 00:17:19,370 --> 00:17:30,170 And if the case is pyramid let's just return the ramp get pyramid like so and the default we will return 250 00:17:30,980 --> 00:17:35,030 ramp get pipe like so 251 00:17:38,450 --> 00:17:40,580 that should work. 252 00:17:40,700 --> 00:17:41,590 It's giving us an Erich's. 253 00:17:41,590 --> 00:17:47,390 It did not return this wonderful wonderful go away read. 254 00:17:47,390 --> 00:17:47,980 There we go. 255 00:17:48,110 --> 00:17:48,430 OK. 256 00:17:48,440 --> 00:17:49,080 Cool. 257 00:17:49,370 --> 00:17:58,460 So back around placer now we can actually get our ramp just by passing in the name of the ramp so let's 258 00:17:58,460 --> 00:18:07,230 ramp equals ramp get ramp for name and we're going to passing the selected ramp OK. 259 00:18:08,170 --> 00:18:15,370 And what we actually need to do here is if the left ramp name equals select the ramp because it's an 260 00:18:15,370 --> 00:18:19,860 optional and it may or may not have a value in it and we don't want to crash. 261 00:18:19,870 --> 00:18:26,110 So this is a time when a user could actually have not done something correctly and it could be nil. 262 00:18:26,140 --> 00:18:29,210 And so we want to make sure we account for it here with the optional. 263 00:18:29,680 --> 00:18:32,390 And in this case we will not say ramp name. 264 00:18:33,130 --> 00:18:39,130 OK so there's our ramp and then let's go ahead and give it a position. 265 00:18:39,130 --> 00:18:43,380 So my tab. 266 00:18:44,050 --> 00:18:44,520 OK. 267 00:18:44,710 --> 00:18:50,130 So the ramp up position is going to be equal to the position where the the finger tap. 268 00:18:50,160 --> 00:18:51,210 OK. 269 00:18:51,360 --> 00:18:52,240 Like so. 270 00:18:52,540 --> 00:18:58,280 And then for the scale we want to set the schedule back to normal size remember on the on the list with 271 00:18:58,300 --> 00:19:00,160 three items made it really small. 272 00:19:00,160 --> 00:19:07,420 We want to do the default size so ramped up scale is going to be equal to SDN vector 3 make and we're 273 00:19:07,420 --> 00:19:16,550 going to say point zero 0.01 0.01 and 0.01 So we're just getting it back to its default size so it's 274 00:19:16,550 --> 00:19:28,890 nice and large and they're going to say seen view that seen that root node not add child node and we're 275 00:19:28,900 --> 00:19:35,700 going to pass in the ramp that we just get from our ramp class. 276 00:19:35,890 --> 00:19:36,920 Cool. 277 00:19:36,970 --> 00:19:38,680 This is really cool. 278 00:19:38,680 --> 00:19:41,070 I'm really curious to see if it works. 279 00:19:41,440 --> 00:19:45,130 So in order to test this we're going to actually have to use it on a device. 280 00:19:45,130 --> 00:19:47,300 So let's do that now. 281 00:19:48,220 --> 00:19:52,780 So I've got my actual phone attached here and I am using the cable you can use the Wi-Fi building but 282 00:19:52,780 --> 00:19:57,940 it's a lot slower that I found so the cable is much faster and I'm going to run it and make sure we 283 00:19:57,940 --> 00:20:00,460 don't have any crashes make sure everything works. 284 00:20:00,670 --> 00:20:05,110 And it may not work perfectly because my office right here is really dark and it needs light in order 285 00:20:05,110 --> 00:20:06,200 to process this. 286 00:20:06,310 --> 00:20:10,280 But I at least want to see if something gets on the screen. 287 00:20:10,280 --> 00:20:11,650 So I'm running the app here. 288 00:20:11,950 --> 00:20:17,170 And of course we see the big half pipe from before because it loads by default we need to get rid of 289 00:20:17,170 --> 00:20:17,700 that. 290 00:20:17,710 --> 00:20:22,400 I think we need to delete the one that's coming up by default so I'm going to stop this real quick not 291 00:20:22,450 --> 00:20:24,320 my recording on my phone. 292 00:20:24,580 --> 00:20:27,200 I was loving and the screen recording pretty nifty. 293 00:20:27,550 --> 00:20:30,540 And let's make sure we get rid of any default have pipes on here yeah. 294 00:20:30,700 --> 00:20:32,090 This pipe that. 295 00:20:32,120 --> 00:20:32,910 Da. 296 00:20:33,130 --> 00:20:41,390 Well we actually want to do is create an empty scene here let's just create a new scene file new file. 297 00:20:41,590 --> 00:20:49,550 We want to do resources and a scene kit scene file and I'm just going to call this main main scene here 298 00:20:50,050 --> 00:20:55,210 save it and I'm just going to put this over here in the our assets folder. 299 00:20:55,390 --> 00:20:59,200 And what I want to do is we go to empty scene which is fine. 300 00:20:59,200 --> 00:21:00,940 So this is good. 301 00:21:01,000 --> 00:21:10,990 What I want to do here is go to our ramp placer and I want to just load this new scene instead this 302 00:21:10,990 --> 00:21:19,460 main scene here OK so we're going to do is change this from pipe that DADT to main dot s c and. 303 00:21:19,610 --> 00:21:20,270 OK. 304 00:21:20,610 --> 00:21:30,030 And what I also want to do here on the scene where we're at is type in scene view auto enable default 305 00:21:30,030 --> 00:21:32,670 lighting to true to set default lighting here. 306 00:21:33,120 --> 00:21:33,660 OK. 307 00:21:34,140 --> 00:21:37,200 So let's go ahead and run this again. 308 00:21:37,330 --> 00:21:49,060 I mean we record it on my phone run it OK it's running in the big huge half pipe is gone. 309 00:21:49,150 --> 00:21:53,130 I'm trying to tap but nothing is happening. 310 00:21:56,170 --> 00:21:59,140 Oh and I know why it's not because we haven't selected one yet. 311 00:21:59,140 --> 00:21:59,930 That's why. 312 00:22:00,340 --> 00:22:05,540 Let's select an object analyst at the pyramid. 313 00:22:05,750 --> 00:22:10,870 We also forgot to dismiss the view controller tap off though and it dismisses fine. 314 00:22:10,930 --> 00:22:13,800 Let's tap somewhere and there it is. 315 00:22:13,810 --> 00:22:14,830 It's definitely working. 316 00:22:14,980 --> 00:22:18,200 As you can see but it's it's found a bad surface here. 317 00:22:18,220 --> 00:22:19,360 Again it's really dark. 318 00:22:19,360 --> 00:22:20,490 You see him moving around here. 319 00:22:20,500 --> 00:22:21,890 You have to do a lot of this. 320 00:22:22,090 --> 00:22:26,330 It's really dark here and it's just not placing it in the right spot. 321 00:22:26,380 --> 00:22:31,030 And so of course we're going to build tools to fix this but also the room is not a great test for this 322 00:22:31,030 --> 00:22:33,910 because it's very dark and it can't detect the walls and the surface very well. 323 00:22:33,910 --> 00:22:38,740 But it did place it there and it's the right size in my opinion so very cool. 324 00:22:38,740 --> 00:22:40,350 So it's definitely working. 325 00:22:40,840 --> 00:22:44,940 We just need to make it a little more accurate so. 326 00:22:45,160 --> 00:22:46,000 So it's working. 327 00:22:46,000 --> 00:22:46,740 We did it. 328 00:22:46,810 --> 00:22:50,770 And if you're going to find yourself when working with Erica you're going be running outside of the 329 00:22:50,770 --> 00:22:52,180 house a lot and moving around. 330 00:22:52,180 --> 00:22:57,490 At least I did when I had to build this made many many trips because the rooms just not a good example 331 00:22:57,500 --> 00:23:01,030 especially since we're doing ramps like high fives they need to be really big and it's not going to 332 00:23:01,030 --> 00:23:02,400 fit in my house. 333 00:23:02,530 --> 00:23:07,060 So we're going to call this video done what we've done is we've actually we refactored some code so 334 00:23:07,400 --> 00:23:13,290 our our assets are usable are seen files are usable and then what happens is we tap on the screen some 335 00:23:13,290 --> 00:23:18,670 where it does detection and then we get the point we grab the ramp and we place it there and it's actually 336 00:23:18,670 --> 00:23:19,820 we've got our air working. 337 00:23:19,840 --> 00:23:24,310 We've accomplished what we need to do but we need to do more cleanup now we need to implement controls 338 00:23:24,310 --> 00:23:28,840 removing things and just create a better solution here altogether so that's it for now. 339 00:23:28,870 --> 00:23:30,420 Let's finish this up. 340 00:23:30,430 --> 00:23:32,800 Mark Price of slopes dot com see assume.
