1 00:00:03,030 --> 00:00:04,770 In this lecture, we're adding another method. 2 00:00:04,770 --> 00:00:08,370 We're adding a transformed translate so we can move our car forward. 3 00:00:08,370 --> 00:00:13,620 And by the end of this video, we'll have our car rotating around and moving forward at the same time. 4 00:00:13,620 --> 00:00:14,580 Let's get started. 5 00:00:14,580 --> 00:00:18,810 We use Transformed Rotate in the previous lecture to rotate our car. 6 00:00:18,810 --> 00:00:23,220 Now we're going to use transform, translate to move the car forward. 7 00:00:23,220 --> 00:00:27,360 We also need to provide the X, Y and z amounts. 8 00:00:27,360 --> 00:00:29,760 We want to move just like we did in rotate. 9 00:00:29,760 --> 00:00:36,780 Let we jump back to rotate over here by opening up my driver script in rotate, we needed an x, y and 10 00:00:36,990 --> 00:00:38,460 z value in there. 11 00:00:38,460 --> 00:00:42,750 In terms of how much rotate, we need to do the same for translate and I'm going to give you these to 12 00:00:42,750 --> 00:00:43,440 you as a challenge. 13 00:00:43,440 --> 00:00:49,740 But first I'm going to comment out our rotation so that we only focusing on the translate for the moment. 14 00:00:49,740 --> 00:00:54,540 We'll uncomment this after we've done translate, but we're going to comment this out for the moment 15 00:00:54,540 --> 00:00:58,020 and I want you as a challenge to make our car move forward. 16 00:00:58,020 --> 00:01:04,890 So in upstate coal transform, translate just as we did with the rotate, we're going to do this with 17 00:01:04,890 --> 00:01:11,790 translate and add the X, Y and Z values you think we need to add in there so that our car slowly moves 18 00:01:11,790 --> 00:01:12,720 forward. 19 00:01:12,720 --> 00:01:18,000 There's a little bit of figuring out going on to do that, but pause the video, take on this challenge. 20 00:01:18,000 --> 00:01:19,950 I'll see you back here when you've given it your best shot. 21 00:01:21,800 --> 00:01:22,400 Okay. 22 00:01:22,400 --> 00:01:28,490 So let us add our new line transform, dot translate. 23 00:01:28,490 --> 00:01:32,960 And you can see I get a couple of letters into it and Visual Studio code saying I think you might want 24 00:01:32,990 --> 00:01:35,330 translate, you can hit space or tab. 25 00:01:35,330 --> 00:01:37,670 I usually use Tab to complete that word. 26 00:01:37,670 --> 00:01:39,290 It's a little bit handy to autocomplete. 27 00:01:39,290 --> 00:01:41,030 We need our parentheses. 28 00:01:41,060 --> 00:01:41,450 Okay. 29 00:01:41,450 --> 00:01:45,890 Now we need to be adding in here the X, Y and Z as we did with our rotate. 30 00:01:45,890 --> 00:01:50,030 I'm not exactly sure what we need, so let's jump back over into unity and have a look. 31 00:01:50,030 --> 00:01:57,050 If I scroll in, click on Cruisy Mic Drive and you can see I want him to go forwards to drive up in 32 00:01:57,050 --> 00:01:58,100 the car direction. 33 00:01:58,100 --> 00:02:05,030 So if I move upwards, what's happening over here in our transform, you can see I'm translating on 34 00:02:05,030 --> 00:02:10,880 the y axis, so I want the Y to be changing and moving in a positive direction. 35 00:02:10,880 --> 00:02:15,560 And that means that when I pop in here, the first one is X, the second one is Y, and the third one 36 00:02:15,560 --> 00:02:15,890 is Z. 37 00:02:15,890 --> 00:02:16,880 So I need zero. 38 00:02:16,880 --> 00:02:21,890 Don't want to move any on the X and then I'm going to put in here one and I think they might be a bit 39 00:02:21,890 --> 00:02:25,580 too big, but I'll put it in any way and then zero because I don't want to move any on the Z and then 40 00:02:25,580 --> 00:02:26,930 the semicolon at the end. 41 00:02:26,930 --> 00:02:28,190 Let's save that. 42 00:02:28,340 --> 00:02:30,320 Let's look to see what happens here. 43 00:02:30,320 --> 00:02:32,270 And I kind of know a little bit what's going to happen. 44 00:02:32,270 --> 00:02:36,740 So I'm going to zoom my camera out a little bit and then click on play. 45 00:02:36,740 --> 00:02:41,810 So every frame we are going to move from way off the screen, we're going to move one on the Y axis. 46 00:02:41,810 --> 00:02:44,210 So we'll jump back into here as we do with rotate. 47 00:02:44,210 --> 00:02:50,270 We'll make this I'm going to make it 0.01 f remember if you're using decimal places, we want to pop 48 00:02:50,270 --> 00:02:51,440 an F down the end. 49 00:02:51,440 --> 00:02:52,400 Save that. 50 00:02:52,400 --> 00:02:55,010 We'll see if this is a little bit more of sensible movement. 51 00:02:55,100 --> 00:03:02,180 I'm going to click on play once we're finished doing all this compiling and we should see slowly heading 52 00:03:02,180 --> 00:03:03,320 in a forward direction. 53 00:03:03,320 --> 00:03:03,620 Excellent. 54 00:03:03,620 --> 00:03:04,610 That's what we wanted to do. 55 00:03:04,610 --> 00:03:05,900 Now I can do something a little bit tricky. 56 00:03:05,900 --> 00:03:09,650 I'll uncomment our rotate and save. 57 00:03:09,650 --> 00:03:14,930 Make sure you always save, jump back over into unity and I'm going to move my car over to the right 58 00:03:14,930 --> 00:03:19,100 because I know already that when we rotate, we're going to be heading rotating in a left. 59 00:03:19,100 --> 00:03:19,550 What's that? 60 00:03:19,550 --> 00:03:23,150 Left is anti clockwise or counterclockwise direction. 61 00:03:23,150 --> 00:03:27,110 So when I click on play now we're going to move forward a bit, rotate a bit, forward a bit, rotate 62 00:03:27,110 --> 00:03:28,370 a bit forward a bit, rotate a bit. 63 00:03:28,370 --> 00:03:31,250 That's how we're going to drive around in this nifty kind of circle. 64 00:03:31,250 --> 00:03:36,320 So we've now added translate to move our vehicle forward on the Y axis. 65 00:03:36,320 --> 00:03:41,060 And we still have in our rotate there and we're rotating around the Z axis to have our vehicle just 66 00:03:41,060 --> 00:03:42,410 going around and around in circles. 67 00:03:42,410 --> 00:03:47,840 Not much of a game just yet, but we're well on our way to adding player control so we can make a game. 68 00:03:47,870 --> 00:03:48,320 Good work. 69 00:03:48,320 --> 00:03:49,460 I'll see you in the next lecture.
