The second link is Id Software’s original C codebase, while the first link is my. You can use either of the two codebase’s. Q3A 1.32b native C Source (original Id Software code with VS 2003 project files).You can download it from one of the following links: The first thing you’ll need to do is get the source code for Quake III Arena. In my opinion this method is the easier of the two anyway. These DLL’s are no different from any other Win32 DLL – the operating system executes these DLL’s as native machine code whenever the Quake III engine needs to call a function contained within them.ĭue to the extreme difficulty I experienced trying to load a QVM mod (as explained in a previous Quake III mod post), I’m going to focus on the creation of DLL mods for this post. These files are very similar to Java bytecode – they contain instructions that the Quake III engine interprets at runtime.ĭLL mods are created by compiling your source into a Windows DLL. QVM mods are created by compiling your source into a QVM file. The only difference is how these mods are executed at runtime. A QVM mod will have the same effect in the game as a DLL mod.

It doesn’t matter which type of mod you make.

The first thing you’ll need to know is that there are two types of Quake III mods: Quake III doesn’t do what is typically done by other games these days – which is wrap all game modding into some form of scripting language (such as Lua) or abstract things to the point where you don’t need to be a game programmer or familiar with the entire codebase in order to make simple behavioral changes. You’ll need to be at least somewhat familiar with C programming in order to make a mod. Now that the Quake III port is done, I can write about creating a mod instead of just installing one.
