> I am not sure about animations on tilemaps, but when i did such a game i made blocks using sprites with animations, 1 frame has the block, 1 frame has the block slightly damaged, last frame has it more damaged etc. I set the animation speed to 0 and i just switch frames from 0 to 1 on collision.
wouldnt having so many sprites lag out the game?
Depends on if all of the blocks should be breakable, if so, then yes would be to much, but you can use multiple tilemaps aswell, not sure how to fit in animations tho, but you can change a tile to another cracked tile on hit, then destroy tile.
