Swarm

Swarm is a 2D programming and resource gathering game. Program your robots to explore the world and collect resources, which in turn allows you to build upgraded robots that can run more interesting and complex programs.

The implementation is still in an early stage, but planned features include:

• Practically infinite 2D procedurally generated worlds
• Simple yet powerful programming language based on the polymorphic lambda calculus + recursion, with a command monad for describing first-class imperative actions
• In-game tutorial
• Multiple game modes:
  • In Classic mode, you start with the ability to produce only very basic, limited robots; collecting resources allows you to bootstrap your way into programming more sophisticated robots that can explore more of the world, collect more resources, etc.
  • Hardcore mode is like Classic mode, but you start with only a limited number of robots. If they get stuck or you run out of resources, it's game over!
  • Sandbox mode places no restrictions: program robots to your heart's content using whatever language features you want, without worrying about collecting resources.
  • In Challenge mode, you attempt to program robots in order to solve pre-designed puzzles or challenges.
  • Future versions might also have multiplayer modes, with co-op or PvP play over a network...?

Installing and Playing

Warning: Swarm is still in an early stage; it's missing many of the planned features, there is no winning condition, and the gameplay is not very deep yet. But you can program cute little robots, and hey, that's all that really matters, right?

NOTE: Swarm requires a POSIX-style environment that supports terminfo. On Linux and OSX, the below instructions should work natively. On Windows, see the comments on this GitHub issue for instructions getting it to work under the Windows Subsystem for Linux.

The recommended way to install Swarm at the moment is as follows:

1. Clone the Swarm repository, e.g.

   git clone https://github.com/byorgey/swarm.git
   

2. If you don't already have the stack tool:

   1. Get the ghcup tool, a handy one-stop utility for managing all the different pieces of a Haskell toolchain.

   2. Use ghcup to install stack:

      ghcup install stack
      

3. It is recommended that you use a relatively large terminal window (e.g. 132 columns x 43 rows or larger).

   • To find out the size of your terminal, you can type stty size.

4. Now use stack to build and run Swarm:

   cd /path/to/the/swarm/repo
   stack run
   

5. Go get a snack while stack downloads a Haskell compiler and all of Swarm's dependencies.

6. Have fun! At the moment, you probably want to take a look at the tutorial to help get you started. Eventually there will be an in-game tutorial.

If you want to contribute, you're most welcome! There are lots of ways to contribute, regardless of your Haskell background. For example, even someone with no Haskell experience whatsoever could still help with e.g. game design, playtesting, and level design for challenge mode.
