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