AGI Workshop -- Day 05

I tried to import 2D animation into Unity. After trying, I found that GIF and normal animation formats were not feasible in Unity. Finally, I used Sprite function to make 2D animation.
I tried to use Playmaker's editor to control the trigger animation, but when we tried the built-in actions like "Set Animation Bool" and "Play Animation", I found that the face can't go back to the original state.
Consider other ways to trigger an expression.--other animation system or script.
