+00:00:00,830 --> 00:00:04,000
+Now let's try to improve our animation even more.
+
+2
+00:00:04,010 --> 00:00:09,210
+Look - the elements of the background are moving with different speed.
+
+3
+00:00:09,440 --> 00:00:15,050
+That creates an illusion of depth and makes our animation more impressive.
+
+4
+00:00:15,050 --> 00:00:17,860
+This effect is called parallax.
+
+5
+00:00:17,990 --> 00:00:21,350
+And in this lesson I'll show you how to achieve it.
+
+6
+00:00:21,410 --> 00:00:26,620
+First, we'll need a background separated into layers.
+
+7
+00:00:26,770 --> 00:00:28,440
+Go to "bg-forest-2"...
+
+8
+00:00:28,660 --> 00:00:33,070
+...and here we can find three components of our background.
+
+9
+00:00:34,480 --> 00:00:36,800
+Let's start with the first one.
+
+10
+00:00:37,150 --> 00:00:42,210
+Please make sure to group it before scaling down. 
+
+11
+00:00:42,280 --> 00:00:46,940
+In this way we won't need to manually scale every other piece of the background.
+
+12
+00:00:47,020 --> 00:00:54,250
+We need a long background, so I create a copy of this image holding SHIFT button...
+
+13
+00:00:54,300 --> 00:00:56,530
+...and move it to the left.
+
+14
+00:00:56,530 --> 00:01:03,140
+Now group these two layers and name it number one.
+
+15
+00:01:03,230 --> 00:01:05,600
+Let's import the next piece.
+
+16
+00:01:05,780 --> 00:01:10,900
+Move it into a group and it automatically scales to the proper size.
+
+17
+00:01:11,050 --> 00:01:12,900
+Put it into the right place.
+
+18
+00:01:20,750 --> 00:01:24,330
+Now make a copy, align it...
+
+19
+00:01:26,950 --> 00:01:28,120
+Done.
+
+20
+00:01:28,310 --> 00:01:31,380
+Also make a group and name it number "2".
+
+21
+00:01:34,650 --> 00:01:36,050
+And the last part.
+
+22
+00:01:38,810 --> 00:01:42,710
+Move it into the group and put to the right place.
+
+23
+00:01:48,810 --> 00:01:54,270
+Great. Now we have a beautiful long background.
+
+24
+00:01:54,450 --> 00:01:56,400
+We only miss the sky.
+
+25
+00:01:56,520 --> 00:01:59,160
+I'm going to use Gradient Tool to create it.
+
+26
+00:02:01,170 --> 00:02:06,270
+Let's choose proper colors.
+
+27
+00:02:06,380 --> 00:02:10,360
+And this one is better to keep white. 
+
+28
+00:02:10,360 --> 00:02:16,610
+Activate Gradient Tool and make sure that you have linear gradient type enabled in the parameters panel.
+
+29
+00:02:16,610 --> 00:02:22,640
+I strongly recommend you to try other types of gradient later in your free time.
+
+30
+00:02:22,640 --> 00:02:26,740
+Now let's drag a vertical straight line on the workspace.
+
+31
+00:02:26,750 --> 00:02:27,860
+Here it is.
+
+32
+00:02:27,920 --> 00:02:29,730
+We have a gradient.
+
+33
+00:02:29,810 --> 00:02:33,870
+You can tweak it by moving this control points.
+
+34
+00:02:33,890 --> 00:02:36,410
+The background is ready now.
+
+35
+00:02:36,470 --> 00:02:38,750
+Now, let's import our character.
+
+36
+00:02:38,750 --> 00:02:43,530
+You probably remember that it's located in "character-2", "final".
+
+37
+00:02:43,580 --> 00:02:45,870
+Here it is.
+
+38
+00:02:45,940 --> 00:03:00,360
+Now let's animate the background in the same way as we did in previous lesson. 
+
+39
+00:03:00,450 --> 00:03:05,750
+Set the Reds Mark. Turn on the animation mode. Go to 14th frame.
+
+40
+00:03:09,360 --> 00:03:18,600
+Move the background. Set linear interpolation here. And go to the end of our animation.
+
+41
+00:03:18,710 --> 00:03:23,420
+Now on the Graphs Tab set the final position of the background
+
+42
+00:03:34,980 --> 00:03:36,810
+Done.
+
+43
+00:03:36,860 --> 00:03:44,330
+Now we have exactly the same animation as in previous lesson.
+
+44
+00:03:44,510 --> 00:03:47,490
+By the way, this red circle can be hidden now.
+
+45
+00:03:48,360 --> 00:03:51,300
+And this waypoint also can be removed.
+
+46
+00:03:51,300 --> 00:04:00,490
+Now let's get to the magic of parallax effect. Click group number two and add a "Translate" layer above it.
+
+47
+00:04:00,510 --> 00:04:08,900
+Background layer number two is more distant than trees on layer "1". And that means it should move slower.
+
+48
+00:04:09,310 --> 00:04:16,090
+So, we have to move this layer in the direction opposite to the background "1" movement.
+
+49
+00:04:16,210 --> 00:04:17,680
+The background is moving to the right...
+
+50
+00:04:17,680 --> 00:04:27,800
+...so we will move layer "2" to the left. Like this.
+
+51
+00:04:28,010 --> 00:04:32,630
+Look, we have already got some feeling of depth.
+
+52
+00:04:32,720 --> 00:04:37,220
+Let's do the same for Layer "3". Add "translate" layer...
+
+53
+00:04:40,110 --> 00:04:41,460
+...and move it to the left
+
+54
+00:04:44,550 --> 00:04:45,050
+Done.
+
+55
+00:04:47,930 --> 00:04:52,640
+Congratulations, we've just made an animation with parallax effect!
