Which is more efficent in this scenario - tilemap or sprite?

Hi,

I'm trying to make a tile-able staircase for my level designer. Wondering if I should use sprites or tilemap is appropriate for this situation. Here's an example of what I mean:

A shows the collision polys, B shows the object polys. If the tilemap collisions are completely unused, do they use any processing power or extra memory?

Thanks.

Tilemaps are generally better for performance. And if you don't have any events/behaviors that require collision checks, then collision polygons don't matter.

Thanks for the reply! I actually tested it by cloning a few hundred of both and found the tilemap to be way laggier for some reason... Is each tile is being rendered as it's own sprite?

No, I meant one tilemap with 1000 tiles is much better for performance than 1000 sprites.
