为什么按钮动画无法在Unity中触发？

Question

After adding GameObject to Hierarchy, I added Image and Button components.

I then set the button's transition settings to animation.

I created a button controller and added sprite images to Normal, Pressed, Highlighted, and Disabled, respectively, to create an animation.

Normal animation works well, but Pressed, Highlited animation does not.

Why is this a problem?

Due to this problem, we are unable to proceed to the next step. Please help me.

If you are using the Image and Button components that are part of the Unity UI ( Component -> UI -> Image ) then these components require a Canvas in order to render.

Instead of creating an empty game object and adding these components manually, use the GameObject -> UI -> Button menu option. Unity will automatically add the new GameObject to an existing canvas, or create one.
