[C++ / SDL] Zoom out & in on tilemap

Alan Smithee · 2012-01-04T14:26:29

Hello. As the title say i want to be able to zoom in and out on a tilemap in SDL. As i zoom, I want the tiles in the map and sprites that are not attached to the tilemap to scale at the same rate to keep proportions. I also want to scale the hitbox at the same rate as well. My question is, simply put: how? I am not looking for a solution but rather a way to tackle this problem cous im at a loss. I tried to search google, gamedev and other sources and found some information (http://www.gamedev.net/topic/437754-sdl-zoom-source-bigger-than-the-screen/) that comes close to what i am looking for but i dont fully understand the concept so i don't blindly want to use code i dont understand. If there is a general "how to zoom tiles and sprites" or if you have any iformation or experience regarding this i would be very thankful for any tips on how to approach this problem. the tiles and sprites are all devidable by 2 (32x32 tiles and 32x32, 64x32 sprites) and are regulare SDL_Surface* 's. If it matters it is for a 2d top down view game. Thansk in advance / AS

Hi again.

lol point taken ;)

As i said earlier, switching API in the middle of this project might caus more trouble then it will do good.

I will be sure to really check out SFML once done though.
