Create a new animation?
Normally, this would be the way to go. Unfortunately, I may have a 30x30 grass-field.
Creating that much animations by hand is a little too much. It's a little hacky.
You see, i store animations like this
HashMap<ANIMATION, Animation> animations;
Where the first one is an enum, and the second one is the actual Animation class.
EDIT: The enum looks like this:
and so on. Each of these enums has an animation in the HashMap.
Your solution suggests that I do this:
and so on, up to 400 and assign them accordingly. You see how hacky that is?
