EXT CSQC

Introduction

QuakeC code is normally run only on the server as a progs.dat file. Engines which support the EXT_CSQC extension run QuakeC code on the client. This enables the mod to control certain extra features:

• Customize the status bar.
• Adjust models and draw extra things on models (even with only one entity on the server).
• Implement prediction.
• Override the FOV.
• Launch sounds locally.
• Implement what would otherwise require another QSG extension.

By standard, CSQC should be compiled into and loaded from a csprogs.dat. Engines can provide cvars to specify a different name but that isn't part of this extension.

EXT_CSQC is intended to replace as much of the fixed function engine code as possible, without requiring knowledge of the engine code mechanisms and in a way that is consistent with the existing style of QuakeC.

The extension defines the whole csprogs, as well as adding some builtins and constants on the server.
