Source 2013 imgui

This repo contains an imgui implementation for Source 2013 based on the one we developed for Strata Source (Portal 2: Community Edition, Momentum Mod, etc.)

Integrating

1. Add this repo as a submodule to your Source mod
2. Include the VPC file in your client_base.vpc
3. Add the following code to cdll_client_int.cpp

At the top of the file:

#include "imgui/imgui_system.h"

Towards the end of CHLClient::Init:

g_pImguiSystem->Init();

At the start of CHLClient::Shutdown:

g_pImguiSystem->Shutdown();

4. That's it!

Limitations

• Interop with vgui isn't the greatest, as we need to intercept input from vgui itself and redirect it to imgui. An invisible popup panel is used for this purpose.
