# gsctool

Simple `GSC` loader and dumper for `Call Of Duty: Black Ops 1 (T5) (Microsoft Windows)`.

[`https://journal.lunar.sh/2023/gsctool.html`](https://journal.lunar.sh/2023/gsctool.html)

To load the demo `GSC` plugin copy `gsctool` to the games root directory.

This demo will give you a raygun on spawn in zombie mode (solo). 

* `GSC` dumps are written to `gsctool/cache`

> This project is intended to be a starting point for more advanced `GSC` modding.

# Instructions

Run: `git submodule update --init --recursive` to clone submodules.

Then build project using the provided makefile in Windows Subsystem for Linux
and inject resulting `DLL`.

The compiler used for this project is [`tcc`](https://github.com/lunarjournal/tcc) (`Tiny C Compiler`).

Note: You can modify and reload GSC scripts while Black Ops is running by quiting
the level and starting it again.
