I was looking at the way Ashley says to do so in the tutorial: scirra.com/tutorials/253/how-to-make-a-platform-game/page-2
Basically using the animation editor to make a grid-based layout.
I was wondering whether using a tiled sprite instead, and then creating a masking layer, would work as well?
My 'platforms' in my game are suppose to look more organic, and would use a tiled texture. I thought it would be faster to create whole layers of the texture, mask them to the shape I want, and then either use collision polygon or a separate collision box for them.
Would it ultimately be more taxing on the game though? My platform is for PC, but would using so many effects to 'mask' the textures just bog my game down more?
