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.

How to submit changes

Changes can be submitted as pull requests.

A pull request should be as granular as possible and only change one thing at a time. If changes are related or more complex, it would be good to start a discussion on how to approach this, before making a change to ensure it can be merged.

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.

• 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.
