Hi, I’m having some trouble creating new animation clips via script. I have A TON of npcs and skin parts, most of them are just spritesheets organized exactly the same way and already editted. Thing is… making the animator component is pretty boring and very tedious. Since they all behave the same way, I thought about creating a script to automate this work.
The animator is very simple, but I don’t know what I’m supposed to do. I got stuck when I tried to add keyframes to change the sprite in the script.
This is the script I was making to automatically create the skin parts of my player(I was supposed to input the spritesheet and it generates the animator and animation clips). I’ve managed to creat the animator and the clips, but now I have no idea how to create the keyframes. Would love some help!
