SDL2 Versus game tutorial
Wed, 20th March 2024
SDL2 has, for some time now, supported the rendering of triangles, as well as quads, using its geometry API. However, there are a distinct lack of in-depth information showing how to use this API, in respect to making games. So, it's therefore time for a new game tutorial.
This game not only makes use of SDL's geometry API, but also demonstrates how to make a two player split screen game, where each player can configure their controls to their liking. The game sees each player controlling a spaceship, where the goal is to either score more points than their opponent, or eliminate them altogether by stripping them of their lives!
