“Cubes” Game Engine
This project, working title “Cubes”, is a WebGL-based game engine for worlds made of cubical blocks. In order to escape the easy trap of being a Minecraft clone, it is instead programmable, so that the game being played may be redefined interactively.
The unique feature of this engine is that each ordinary block is itself made out of blocks; each block can be “entered” and edited at an enlarged scale, and changes will immediately be seen in the outer world. Additionally, the behavior of blocks can be defined by constructing circuits within them, out of special blocks.
Requirements and startup
No compilation is required; simply serve this directory from a web server (required so that files can be accessed from scripts) and open
cubes.html in a WebGL-supporting browser. Worlds you create are saved in your browser using
I have found the best performance to be with Google Chrome; Firefox is acceptable. Safari 5.1 is incompatible due to lack of correct implementation of ECMAScript 5 accessors.
