Welcome to q3py’s documentation!

q3py is a Quake 3 to Python bridge.

Warning

This is a work in progress and not meant for public use (yet)!

Quake 3 uses separate modules for its game logic, i.e. client, server and user interface. Those modules can be loaded either in QVM (a .qvm file) or shared native library (a .dll, .so or .dylib file) format.

Now q3py is a shared library which implements the API that Quake 3 expects, but it relays all calls to a Python module. To do so, q3py embedds libpython3 and provides a Python extension module to allow the Python code to call back into Quake 3.

digraph q3py {
	subgraph cluster_exe {
		quake3 -> q3py -> libpython3 -> script;
		script -> libpython3 -> q3py -> quake3;

		quake3 [label="Q3"];
		q3py [label=<q3py<br/><i>qagamex86_64.so</i>>];
		libpython3 [label=<Python<br/><i>libpython3.2.so</i>>];
		script [label=<<i>script.py</i>>];

		label=<Quake 3<br/><i>ioq3ded.x86_64</i>>;

What q3py allows you to do is write Quake 3 game logic, also known as “mods”, with Python. However, you need to provide all of the logic. To add e.g. homing missiles to the BFG, you would need to implement players, items, pyhsics and weapons in Python as well, you can not extend upon the C code of an existing Quake 3 game module.
