# gsctool

Simple `GSC` loader and dumper for the `PC` version of `Call Of Duty: Black Ops 1 (T5)`.

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

To load the demo `GSC` plugin copy `gsctool` to the game's root directory.

This demo will give you a `raygun` on spawn in `SP` zombie mode. 

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

> Note: 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 `WSL` (`Windows`)
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.
