Quake3World

I have modeled a few weapons and i'm looking into replacing the stock Q3 ones with mine. However, i noticed that the code responsible for loading weapons is really "coupled" with the stock weapons: there's a lot of switch's and if's depending on the weapon, for loading some parts of the model, or rotating other parts... a real mess.

Does anyone with a better experience with the Q3 codebase could guide me (or point me some tuts/docs) into the job of replacing the weapon models? Which files have weapon-specific loading/switching? For example: to replace the machine gun, i have to alter a few files with MD3 loading of separate parts, and other files to make the weapon rotate (i have to disable that for my model), etc.

Here's a tutorial about adding a new weapon.

It might be a starting point for what you are looking for.
Perhaps somebody else here can help you better detail...

I have noticed that this tut does not cover adding first-person weapon model. How is this done?

Do you really need to alter the code to do this? What's exactly what you want to do? You can take a look at other custom models, it might help.

I just find the whole thing difficult because the code is so tightly coupled. Adding a new weapon is a nightmare.
