since my game is built of sprites and tiles, I wondered if it would run faster, if I convert it all to tilemaps.
An advantage seems to be some spritesheet optimization and less objects in the layout.
On the other hand - it seems - I cannot reduce collision-checks as much, as with separate sprites/tile-backgrounds.
The reason: Since tilemaps are checked for collisions each tile, as they have separated collision-polygons, the number of collision checks is just as high, as if each tile would be a separate object. But separate sprites/tiled-backgrounds can be turned off (solid and collision) when not in range, which cannot be done with separate tiles on one tilemap, or am I wrong?
So is it really worth using tilemaps instead of sprites/tilebgrs performance-wise?
Please give me some advice.
