### DOTS Animation System
Sample code to play an animation.
```C#
protected override void OnUpdate()
{
float deltaTime = UnityEngine.Time.deltaTime;
Entities.ForEach((Entity entity, ref VA_AnimatorComponent ac) =>
{
// Get the animation lib data.
ref VA_AnimationLibraryData animationsRef = ref ac.animationLibrary.Value;
// Set the animation index on the AnimatorComponent to play this animation.
ac.animationIndex = VA_AnimationLibraryUtils.GetAnimation(ref animationsRef, animationName);
// 'Play' the actual animation.
ac.animationTime += deltaTime * animationsRef.animations[ac.animationIndex].frameTime;
}).ScheduleParallel();
}
```
### Shaders
Lit example shader (build in shader graph).
Full shader graph support.
