Generating Anagrams in Lua

I’m working on a game where I need to generate anagrams of words. My new game engine, which is Max Astro’s engine but with a few tweeks, integrates Lua and all the game logic is in Lua.

So given a string like “chicken” I want “kcehcine” or some …

Starter Blender Exporter

I’ve settled on using Blender 2.6 both as a level editor and modeller for my next game (code name BBM). BBM is a 2D game but modelling the characters and rendering the sprites will save a lot of time. Blender isn’t the best level editor but it …

Logical Bit Operators in Lua When Using Floats

I’m making some changes to the codebase that drives Max Astro before making my next game. The biggest change is that the engine is going to be controlled by Lua. Lua will run the main logic loop and lua will be the configuration language.

A Pythonic “Center New” in Blender

Part of my Art pipeline for Tentacles is to import a directory of 3DS files. Each of these files is a map piece and the map pieces are instanced to create a map. That way I can store the geometry for a shack once but instance it across the level …

Implementing glAlphaFunc in OpenGL ES2.0

In OpenGL ES 2.0 glAlphaFunc isn’t available, you have to implement it in a fragment shader. There isn’t a lot of reference out there for this (not that I could find anyway) so I thought I’d write this up.

It’s actually quite simple to implement …

Integrating Bullet Physics

Bullet provides a C++ API to a very robust Collision, Rigid Body and Soft body simulation system. At its core Bullet …
