I'm in a middle of developing my game, which is grid based and I just realised that I could replace almost all my objects with tiles from tilemap. The thing is most of my environment is supposed to have animations. I'm planning to do it by switching tiles on demand or, in some cases, constantly. I have a guess that if I use tile positions to calculate movements for my characters it wll cost less and I will be able to have a lot more action going on without unnecessery collision detection. I don't have a lot of time to experiment and make my own tests, so my question is: is it worth trying to build a game that will mostly have tilemaps and use sprites only for characters and players? Can I win a lot of performance by redesigning my project to be that way? I saw some plugins utilising tilemaps and people seem to be very pleased with their performance. So are tilemaps generally faster then sprites, even if I try to make all my scene animated with them?
