1 00:00:05,800 --> 00:00:11,890 All right let's go ahead and take a look at one more thing with our rigid body simulation and we're 2 00:00:11,890 --> 00:00:17,500 going to see how we can animate and have our animation interact with rigid body. 3 00:00:17,800 --> 00:00:24,430 So let's go ahead and hit shift left arrow go back to the beginning and we're actually going to delete 4 00:00:24,820 --> 00:00:27,790 our wrecking ball. 5 00:00:27,930 --> 00:00:29,350 It's a sad moment. 6 00:00:30,190 --> 00:00:31,540 In history. 7 00:00:31,860 --> 00:00:33,600 All right let's go ahead and delete that. 8 00:00:33,690 --> 00:00:38,190 And now what we're going to do is just simply add in a cube. 9 00:00:38,230 --> 00:00:42,810 And before I do that if I hit all day all right everything is good. 10 00:00:43,060 --> 00:00:48,860 Let's go ahead and add in a cube and bring it here like so. 11 00:00:48,880 --> 00:00:50,510 And scale it up. 12 00:00:50,530 --> 00:00:53,900 Now we're going to animate this cube crashing through the wall. 13 00:00:53,980 --> 00:00:55,630 But we're going to do it in a different way. 14 00:00:55,720 --> 00:00:59,380 Whereas it's not going to be fully rigid body physics. 15 00:00:59,470 --> 00:01:03,710 It is going to be partially but it's also going to be animated. 16 00:01:03,760 --> 00:01:12,040 So if you have an animation of let's say actually we're going to do two examples here so let's go ahead 17 00:01:12,370 --> 00:01:18,790 and grab this cube and see selecting it let's on frame 1. 18 00:01:18,790 --> 00:01:20,070 Go ahead and hit I. 19 00:01:20,140 --> 00:01:27,780 Location stumbling with my words once again not good and hitting g to grab it along the x axis. 20 00:01:27,790 --> 00:01:30,140 Let's bring it to here hit I. 21 00:01:30,310 --> 00:01:31,930 Location. 22 00:01:31,960 --> 00:01:32,230 All right. 23 00:01:32,230 --> 00:01:32,680 Awesome. 24 00:01:32,680 --> 00:01:38,020 So now if we go back to the beginning we can see if we hit all day that's playing but nothing's happening 25 00:01:38,050 --> 00:01:39,720 with our cubes. 26 00:01:40,120 --> 00:01:49,300 So let's go ahead and select our big Q hit rigid body and we are going to not have that active because 27 00:01:49,300 --> 00:01:54,550 if we do that that's going to give us a weird weird result. 28 00:01:54,660 --> 00:01:57,140 We're actually going to change it to passive. 29 00:01:57,400 --> 00:02:01,440 And now if we hit all day you can see that nothing happens either. 30 00:02:01,450 --> 00:02:08,820 So what we need to do is actually click on animated and now it will tell Blendr that basically we have 31 00:02:08,820 --> 00:02:13,980 a passive object but it's also controlled by the animation system. 32 00:02:13,980 --> 00:02:15,650 So if I hit all day now. 33 00:02:16,080 --> 00:02:16,640 Boom. 34 00:02:16,710 --> 00:02:18,450 How cool is that. 35 00:02:18,540 --> 00:02:24,330 A bigger cube killing smaller cube not the prettiest sight in the world but it's really cool because 36 00:02:24,600 --> 00:02:32,080 we could actually use animation in conjunction with rigid body physics and simulation. 37 00:02:32,490 --> 00:02:39,780 All right let's take a look at one last example and that would be for example we're not going to model 38 00:02:39,780 --> 00:02:44,430 and do the whole thing but let's say for example we have and let's move to the side. 39 00:02:44,430 --> 00:02:47,120 Let's do another simulation here. 40 00:02:47,310 --> 00:02:50,140 Let's go ahead and hit shift day and mesh cube. 41 00:02:50,790 --> 00:02:52,440 Let's bring this up. 42 00:02:52,470 --> 00:02:54,720 We're going to pretend that this is a bat. 43 00:02:54,720 --> 00:02:58,640 So s and X let's scale it along here. 44 00:02:59,920 --> 00:03:02,040 And this is going to be our backs. 45 00:03:02,910 --> 00:03:04,100 On frame 1. 46 00:03:04,650 --> 00:03:12,240 Let's actually hit tab to go into edit mode and bring it out this way so that the origin point is right 47 00:03:12,240 --> 00:03:18,510 here so that when we go to object mode it's rotating around that point and it has a swinging motion 48 00:03:18,510 --> 00:03:19,240 to it. 49 00:03:20,190 --> 00:03:23,790 On frame 1 let's rotate it back here. 50 00:03:24,650 --> 00:03:25,120 And hit. 51 00:03:25,170 --> 00:03:27,120 Eye rotation. 52 00:03:27,320 --> 00:03:32,480 And then on frame 20 let's rotate it. 53 00:03:33,390 --> 00:03:34,840 Like so and hit. 54 00:03:34,860 --> 00:03:36,750 Eye rotation. 55 00:03:36,810 --> 00:03:41,420 So now we have this bat or swinging type motion over here. 56 00:03:41,430 --> 00:03:48,420 I'm actually going to grab all of this right here by box selecting hitting em and moving it to the second 57 00:03:48,420 --> 00:03:55,660 layer by pressing two on there so that we are not distracted by the cube. 58 00:03:55,980 --> 00:03:59,560 The cube of destruction that's happening over there. 59 00:03:59,670 --> 00:04:04,880 Now let's go ahead and hit shift day and mesh U-V sphere. 60 00:04:05,040 --> 00:04:09,440 This is going to be our baseball hitting G and Z to grab it. 61 00:04:09,450 --> 00:04:16,570 Let's align it with our bat and let's bring it over here. 62 00:04:16,650 --> 00:04:22,710 All right now let's go ahead and add a rigid body physics option to it. 63 00:04:22,820 --> 00:04:27,620 Let's change it to mash and make sure that's active which it is. 64 00:04:27,680 --> 00:04:31,480 If I hit all day you can see what's happening. 65 00:04:31,520 --> 00:04:37,150 Pretty cool so let's scroll through the timeline and see where it's going to collide. 66 00:04:37,470 --> 00:04:42,670 So you can see right there it's going to collide so the ball needs to be brought a little bit higher. 67 00:04:42,980 --> 00:04:44,680 Let's bring it up to here. 68 00:04:44,900 --> 00:04:49,110 Hit on a once again and scroll through that. 69 00:04:49,320 --> 00:04:51,240 And now it's a little bit too high. 70 00:04:51,420 --> 00:04:57,060 So once again bringing it down let's hit all day. 71 00:04:57,260 --> 00:05:02,820 And that look that looks like it's going to be pretty good right here. 72 00:05:03,800 --> 00:05:09,880 I'm going to bring it down even just a little bit more. 73 00:05:09,880 --> 00:05:10,390 All right. 74 00:05:10,390 --> 00:05:11,090 That should be good. 75 00:05:11,110 --> 00:05:15,640 So now when the bat collides with the ball it's going to be right there. 76 00:05:15,940 --> 00:05:23,840 So all we have to do now with our bat or our cue bat they should make some bats like this for the for 77 00:05:23,840 --> 00:05:25,940 the major league baseball man. 78 00:05:25,960 --> 00:05:27,150 All right let's like this. 79 00:05:27,290 --> 00:05:29,170 Like rigid body. 80 00:05:29,460 --> 00:05:31,890 And we're going the same thing that we did with our other cube. 81 00:05:32,050 --> 00:05:35,440 We're going to change it to passive and animated. 82 00:05:35,650 --> 00:05:36,990 Now rewinding this. 83 00:05:37,000 --> 00:05:39,420 Let's go ahead and hit all day and see what happens. 84 00:05:40,210 --> 00:05:41,210 Boom. 85 00:05:41,390 --> 00:05:42,380 Pretty cool. 86 00:05:42,380 --> 00:05:50,210 So this could be kind of like a baseball animation for example with your animation if you have a baseball 87 00:05:50,210 --> 00:05:55,850 animation like I'm saying you wouldn't you could animate this easily. 88 00:05:55,850 --> 00:06:01,790 You could animate a baseball bat easily and even a ball you can animate depending on what you want your 89 00:06:01,790 --> 00:06:02,750 animation to be like. 90 00:06:02,750 --> 00:06:04,930 You would probably animate the ball as well. 91 00:06:05,180 --> 00:06:12,140 But let's say you want it to have like a natural flow to it and for it to be bouncing and interacting 92 00:06:12,140 --> 00:06:18,870 very naturally you could actually have your bat be a passive rigid body. 93 00:06:19,040 --> 00:06:23,930 And then in your animation make your baseball bat be a rigid body as well. 94 00:06:23,930 --> 00:06:24,740 Excuse me. 95 00:06:24,950 --> 00:06:32,750 And then when your ball is thrown towards your bat it will interact and just like this you can see that 96 00:06:32,840 --> 00:06:35,420 interacts with our bat. 97 00:06:35,420 --> 00:06:36,170 Pretty cool. 98 00:06:36,170 --> 00:06:44,630 So this allows for you to have much more control over you know having more randomness to it. 99 00:06:44,720 --> 00:06:49,580 And if it's some kind of bouncy ball we could increase the bounciness because as you saw we hit when 100 00:06:49,580 --> 00:06:55,830 we hit Allt a it's just kind of sliding after on the floor kind of unrealistic. 101 00:06:55,830 --> 00:07:01,700 So let's go ahead and increase the bounciness and the bounciness on here is already increase. 102 00:07:01,710 --> 00:07:03,010 So that's here all day. 103 00:07:03,630 --> 00:07:07,820 And now you could see that it bounces on here. 104 00:07:08,250 --> 00:07:13,240 Let's do one more thing selecting our floor hitting tab to go into edit mode. 105 00:07:13,450 --> 00:07:20,820 Let's hit control tab go to edge select mode select this edge Eido extrude and Z and we're going to 106 00:07:20,820 --> 00:07:23,710 make a wall here. 107 00:07:23,750 --> 00:07:24,050 All right. 108 00:07:24,050 --> 00:07:24,890 Awesome. 109 00:07:24,890 --> 00:07:34,760 Now let's go ahead and hits all eight aplay and now it's actually interacting very weirdly because bounciness 110 00:07:34,760 --> 00:07:35,650 is all the way up. 111 00:07:35,870 --> 00:07:40,770 So actually I have no idea what's happening with the ball. 112 00:07:40,880 --> 00:07:42,190 Let me see the ball. 113 00:07:42,190 --> 00:07:43,530 What's happening with it. 114 00:07:43,720 --> 00:07:47,170 So the ball we can see is actually 115 00:07:50,220 --> 00:07:54,460 dynamic animated it's passive. 116 00:07:54,530 --> 00:07:56,250 Let's change this to mesh. 117 00:07:56,260 --> 00:07:58,040 Possibly. 118 00:07:58,060 --> 00:07:59,270 There we go. 119 00:07:59,360 --> 00:08:00,160 That's a little bit better. 120 00:08:00,160 --> 00:08:08,230 So we need a change the rigid body constrain or collision type from convex hull because you can see 121 00:08:08,230 --> 00:08:14,170 when this is here it's having some weird effects and change it to mesh. 122 00:08:14,200 --> 00:08:14,530 All right. 123 00:08:14,530 --> 00:08:21,980 Now let's increase the bounciness back up hit all day and you could see what's happening. 124 00:08:22,000 --> 00:08:23,550 Pretty cool. 125 00:08:23,560 --> 00:08:26,520 So that is rigid body physics. 126 00:08:26,530 --> 00:08:30,480 One last thing I want to take a look at is basically over here. 127 00:08:31,610 --> 00:08:38,890 This is a rigid body physics so it's actually not animated but we could turn this into an animation. 128 00:08:39,050 --> 00:08:44,040 If we go over here we could see that this has no keyframes in here besides the road. 129 00:08:44,060 --> 00:08:49,070 Or actually let's take the ball for example because this has two two key frames and they're rotating 130 00:08:49,070 --> 00:08:54,120 it but the ball has no key frames in there. 131 00:08:54,200 --> 00:08:57,670 This is right here you could see little orange frames. 132 00:08:57,680 --> 00:09:05,570 And this is basically blender that calculated the rigid body physics of it and kind of temporarily saved 133 00:09:05,570 --> 00:09:08,960 it here so that it doesn't have to recalculate it every time. 134 00:09:08,960 --> 00:09:11,810 But as far as keyframes there are none here. 135 00:09:12,110 --> 00:09:19,790 Now we could actually turn this rigid body simulation into a keyframe animation so that we can have 136 00:09:19,790 --> 00:09:22,040 more control over it in the future. 137 00:09:22,040 --> 00:09:24,560 And the way we do that is just going over here. 138 00:09:24,740 --> 00:09:25,850 You could apply. 139 00:09:25,880 --> 00:09:30,320 You could actually go here and bake to keyframe. 140 00:09:30,470 --> 00:09:37,250 So it will bake the rigid by simulation to key frames so let's go ahead and click that and we're going 141 00:09:37,250 --> 00:09:39,840 to put the end frame. 142 00:09:39,930 --> 00:09:43,660 Let's just put and frame 150 so that's not too much. 143 00:09:43,920 --> 00:09:47,730 And then click OK. 144 00:09:47,880 --> 00:09:56,610 Now you could see that what they that's turned this rigid body simulation into an actual keyframe animation 145 00:09:57,000 --> 00:10:03,840 of our ball and we actually go in here and now that they're keyframe we could even delete some of the 146 00:10:03,840 --> 00:10:05,280 key Fringe's by hitting Alt. 147 00:10:05,310 --> 00:10:13,290 I if we want delete keyframe and really having more control over this and even going in the graph editor 148 00:10:13,530 --> 00:10:20,340 and having more control because now you can see that in our physics our rigid body tab it's no longer 149 00:10:20,340 --> 00:10:25,070 a rigid body but it is an animated object. 150 00:10:25,320 --> 00:10:31,530 So that's a really cool way that you could also do some of your animations using the rigid body and 151 00:10:31,530 --> 00:10:35,000 then converting it into a keyframe animation. 152 00:10:35,010 --> 00:10:35,520 All right. 153 00:10:35,580 --> 00:10:41,850 I think I drove that point home long enough again again repetition is the mother of all skill. 154 00:10:41,850 --> 00:10:45,060 Sorry if I repeated it too much but I think you get the point. 155 00:10:45,060 --> 00:10:46,650 So that's rigid body physics. 156 00:10:46,650 --> 00:10:48,810 Super cool super awesome. 157 00:10:48,810 --> 00:10:51,580 And just go crazy have some fun with it. 158 00:10:51,630 --> 00:10:54,410 I'll see you in the next story all of us. 159 00:10:55,080 --> 00:10:57,750 All right ladies and gentlemen here we go. 160 00:10:57,750 --> 00:11:02,440 Here we go one more time to see the reality in the lie. 161 00:11:02,490 --> 00:11:08,670 You have to be willing to say goodbye to what you once believed in for so long and once you let go you'll 162 00:11:08,670 --> 00:11:10,320 become so strong. 163 00:11:10,620 --> 00:11:11,160 All right. 164 00:11:11,160 --> 00:11:15,020 Once again what you believe is not necessarily true. 165 00:11:15,030 --> 00:11:17,310 So take a look at what you believe. 166 00:11:17,310 --> 00:11:21,190 Appreciate you guys and believe the one thing that blender is awesome. 167 00:11:21,240 --> 00:11:23,480 So I'll see you guys next Tauriel. 168 00:11:23,480 --> 00:11:23,910 Chop.
