2D platformer + shooter engine and game written in C

Learn how to create a 2D platformer shooter in an arcade style with C and OpenGL.

The purpose of this game, engine, and series is to teach how to create a game without using a 3rd party engine.

The point is to show that one does not need to build every feature or create the most complex, general solutions to problems in order to have a shippable product.

What this is not

• The most efficient or flexible way to solve problem X.
• A replacement for a general 3rd party engine.

Current feature list

Everything on this list will be or has been implemented in the video series, and exists in one form or another in this codebase.

• Simple sprite rendering with OpenGL.
• Simple physics integration.
• AABB discrete and continuous collision detection and response.
• Custom serialisation (handling configuration file).
• Sound mixing.
• Simple entity system.

Potential future feature list

I have created or are working on these features in my current game project which uses a forked version of this engine. If there is enough interest I may create tutorials for them in the future. I will post a video and poll at the end of the current series.

• Batch renderer.
• Tile-based levels.
• Custom memory allocators.
• Custom vector math library.
• Custom immediate mode UI library.
• Scene management.
• Decoupled game loop.
