[MUSIC] Animation is one way to add visual polish to our game. We'll discuss the animation tools in much more detail in the future. But for now, let's just create a simple animation. Our objective will be to create a simple animation shimmer on the DeathZone gameObject to communicate the fact that it's dangerous to the player. Okay, the first thing that I'm gonna need to do to create my animation is select the DeathZone game object. Of course I can find it in the environment, but we haven't actually used the hierarchy search, so let's go ahead and do that. So up here at the top of the hierarchy I can just start typing Death and there it is. It basically modifies the hierarchy just to select or just to highlight the things that we're searching for. If I cancel out, it will actually show the entire hierarchy and show the actual object that I selected, which is a nice feature. One other nice editor thing that we haven't looked at yet is actually full screening panes. So with your mouse, over one of the areas of the editor, you can just hit Shift + Spacebar. And it basically makes the scene view, in this case, full screen. And of course, I can do all the things that I do with the scene view, and then hit Shift + Spacebar to go back. If I want to highlight the hierarchy, I can do Shift + Spacebar over the hierarchy and it makes that full screen, Shift+space to reduce that. So there's some other nice editor things that you can pick up along the way. So we're gonna create an animation. So the game object is selected and the way that we create an animation is through the animation system. We haven't looked at that yet so let's go ahead to the window and you can see there's animation right here. So we're gonna open up the animation window which is Cmd+6 or Ctrl+6 on Windows. This is a pretty straight forward animation editor as we'll see. It says to begin animating DeathZone create an Animator and an Animation Clip. So the way that animation works is it attaches an Animator component to the game object, and then the Animator component uses Animation Clips to actually create the animation. We'll be looking at animations in much more detail down the road, but we're just gonna create a simple animation today. So let me go ahead and click Create. Animation is actually an asset just like your other assets. So there'll be a file in the project. And I'm gonna go ahead and call this my DeathZone Animation and you can see it actually created a DeathZone Animator in my project. And it attached it to my game object, you can see it right here and it created a DeathZone Animation. So it sort of seeded it with one animation. And you can see right here in the animator, right now I've got that DeathZone Animation showing. There's no data yet, but there it is. And you can create additional clips, right here, in the interface. But we're just gonna have one animation. Working with this animation system, this is where multiple monitors would be nice. But since we don't have that here, I'm going to actually take this window and I could drag on the tab and bring it right down into one of the panes. So now I've got the game view and the animation. So I can actually see this in my standard interface and not have it in a separate window, which is kind of nice when working with animation. The animation editor is pretty straight forward. We've got a timeline here. It goes from zero time to one second. It's based on the number of samples, 60 samples. We can, of course, increase that, but it will work fine for what we're doing here today. And notice Record is hit. So I can hit that to stop recording. But when the Record button is pressed, basically the things that I do in the editor will actually record. So with the DeathZone game object, let me go over to the Materials. And I'm gonna go ahead and pick the color swatch for the tint of the Albedo texture. And let me go ahead and drag this down a little bit to make it slightly darker. And you can see, over here in the animation editor, because I'm recording, it actually created a key frame for the item that I just did. Let me move out in time a little bit, so I can just click up in the timeline. Let's move out to 0.2 and open up editor again. Let me go back to maybe about where it was, kind of a bright red. And there you can see another key frame was created and then let me go out a little farther to maybe 40. And open up the editor again and ideally I get the exact same red color because it's gonna loop. So I'm just gonna eyeball it here about to there and then let me sample this clip. So press Play and you can see it's basically cycling from the dark to the light and back to the dark. And once again I probably would want to be precise with this to have the exact same color for the looping to take place. Now this is just one property. I can of course edit additional properties. So with the Record button still selected, I could go back here and let's say I'm just going to move it down a little bit to -2.1, set that key frame. Come out here to 0.2 again, and set it back to -2. Come out a little bit farther, and set it to -2.1. And once again I can play again and you can see that it's changing the color and it's slightly moving it up and down a little bit. Okay so my animation is essentially done. I can untap record so I'm not recording anymore and I can switch back to the game view. So if I actually play the game now, you can see that that effect is happening. And of course I can go back and play with this additionally. Now one thing of note is since this has a box collider on it and now we're moving it with animation, we should probably have a RigidBody component on the DeathZone just for optimization purposes. So let me go ahead and add the RigidBody component. And, since we are moving it through animation, we certainly don't want gravity and we want Is Kinematic because it is being driven by animation. So that'll just speed up the game due to efficiencies and how the Unity engine works. In the next video we'll finish off our game by spawning additional pick-ups and enemies in the game. [MUSIC]
