Say, you have a single Enemy sprite with animations Zombie, Skeleton and Goblin.
Put 3 copies of this sprite on Assets layout. Configure the animation and instance variables like HP, armor etc. And give a name to each template:
When you create an Enemy from "goblin" template, it will be created with the correct animation and variable values.
Templates are not related in any way to animations. You can have multiple templates with the same animation, for example "zombie_soldier", "zombie_medic"
