Minecraft (Craft)¶
Background¶
A simple Minecraft clone written in C using modern OpenGL (shaders).
Features¶
- Simple but nice looking terrain generation using simplex noise.
- Biomes
- Water
- More than 20 types of blocks and more can be added easily.
- Supports plants (grass, flowers, trees, etc.) and transparency (glass).
- Simple clouds in the sky (they don't move).
- Day / night cycles and a textured sky dome.
- More sophisticated sunrise/sunset color blending
- Ambient occlusion for basic shading of blocks.
- World changes persisted in a sqlite3 database.
- Configurable draw distance. The draw distance has a big effect on the framerate, a draw distance of 1 or 2 can make this core playable even on very lightweight computers.
- Configurable field of view.
- Gamepad support (including analog stick support) configurable analog sensitivity and deadzones, preliminary mouse and keyboard support.
- Configurable resolutions, up to 4K.
- A ‘Jumping Flash’ mode that allows you to jump infinitely into the air all while the camera faces downwards.
