Alien Swarm: Reactive Drop

Alien Swarm: Reactive Drop is a standalone modification for Valve's Alien Swarm game. This repository contains the source code for Alien Swarm: Reactive Drop. Using Visual Studio you will be able to build these DLL files: client.dll, missionchooser.dll, server.dll.

What is this repository for?

Having access to the source code you can:

• Add new weapons, NPCs, fix bugs and generally add new features to the game and submit them as pull requests
• Create mods. Both server side and client side mods. Or fully standalone mods

How to download the repository

There are two branches in this repository:

• master branch is the original Alien Swarm source code provided by Valve
• reactivedrop_public branch is the up to date Reactive Drop source code

Tip: It is better to make a fork of this repository before cloning it and work on your own fork. Do this using a button in the top left. The URL for your forked repository will be different from the one shown below.

• Download and install Git for Windows.
• Open Git Bash
• Input commands into Git Bash

    git clone https://bitbucket.org/reactivedropteam/reactivedrop_public_src.git
    cd reactivedrop_public_src
    git checkout reactivedrop_public

How to compile the project

• Download and install Visual Studio 2013(https://visualstudio.com/vs/older-downloads/). You will need to register a free account in order to download. Visual Studio 2015 and 2017 might work too if you use the Visual Studio 2013 toolchain. Visual Studio 2005 and up can also be used, but we didn't update the project files for them, thus you will need to add Reactive Drop's new files(.cpp and .h) into solution(reactivedrop.sln)
• Open reactivedrop_vs13.sln using Visual Studio 2013
• Select configuration Debug or Release
• Build
• Resulting DLLs will be placed into reactivedrop\bin

How to modify content files

The reactivedrop folder contains games content: materials, models, scripts, sounds. For now it contains the bare minimum of files to save the repository space. If you want to add new or modify the existing game content files please do it in two commits:

• First commit only adds unmodified content files. You can get them from the Alien Swarm: Reactive Drop game folder
• Second commit introduces your modifications to both content files and, if necessary, source code

This way we will be able to see which changes did you introduce to the content files.

Reactive Drop Team is happy to accept pull requests and issues in the reactivedrop_public_src repository in these cases:

• Changes that fix bugs in the SDK deployment process itself. The repository should build out of the box, and anything that prevents that is a pull request we want.
• High priority bugs in Alien Swarm: Reactive Drop, that can be fixed in client.dll or server.dll.
• New weapons, NPCs, features.

If you are going to make a pull request, please keep them as granular as possible. Pull requests with 3-4 unrelated changes in them aren't going to be accepted.
