Make Your First 3D Game Fast – Block Maze Racer
Venturing into designing 3D games can be intimidating. I mean, it is another entire dimension of complexity. This game is simple by design. The player is an awesome happy block with a great haircut, I might have designed the 3D model, the level is an ever changing maze, and the goal is to not hit the walls. Starting with simple objectives and assets allows for us to more deeply explore the physics, object interaction and camera manipulation that makes the massive billionaire franchises so fun to play. All the code and assets are linked below, everything is free to use and build with. Make an awesome game and have fun!
