Screeps

The world's first MMO sandbox game for programmers

What is Screeps?

Screeps means “scripting creeps.” It’s an open-source sandbox MMO RTS game for programmers, wherein the core mechanic is programming your units’ AI. You control your colony by writing JavaScript which operate 24/7 in the single persistent real-time world filled by other players on par with you.

Deployment

1. Install Dependencies with npm install.

2. Create a .screeps.json file with the following content:

   {
     "email": "foo@bar.com",
     "password": "SecretPassword",
     "branch": "default",
     "ptr": false
   }
   

3. Then run grunt screeps.

Ideas/Improvements

• Create a scheduler for energy harvesting, sometimes the creeps get to the container which is empty yet.
• More complex spawn system than just a priority list.
• Expand harvesting to neighbor rooms.
• Make more use of the memory to save cpu power.
