So this is my application thus far, programming with c++, sdl and opengl. You can move around the map and all that good stuff, but there is no minimap, which is something I really want to create.
I wanted to know how I would go about creating a texture in opengl (using the data from each tile of the map) to draw a map representing each tile as a pixel, and applying this image to a quad which will occupy the black square.
I need to know all the syntax and have steps explained.
Help is very much appreciated! Hope you guys can help.
