Make sure to use git clone --recurse-submodules to clone this repo. (so you can get art assets from original tutorial).

YourFirstGame in Haskell

Example of converting the YourFirstGame godot tutorial to Haskell with godot-haskell library.

You can find the original tutorial here: https://docs.godotengine.org/en/3.2/getting_started/step_by_step/your_first_game.html

Quick Start

1. Build the Haskell library stack build

2. Copy the Haskell library to the game folder (change .so to .dynlib in Mac or .dll in Windows) cp $(shell stack path --local-install-root)/lib/libgodot3-dodge-haskell.so $(shell stack path --project-root)/game/lib

3. Copy over art assets from the original tutorial repo cp -rf Godot3_dodge/art game/art

4. Get a copy of Godot engine from Godot's website: https://godotengine.org/. This was tested with Godot version 3.2.1

5. Add and make sure the generated .so/.dynlib/.dll is loaded correctly in Godot project. NOTE Godot may remove the signals / baseclasses of the GDNativeScript classes in project.godot during this step. Make sure to add them back or it won't work.

6. Run with Godot Godot --path ./game

• NOTE Only tested in Linux so far.

Structure

• Haskell source is in src.
  • src/Lib.hs contains the Godot class exports.
  • src/Util.hs contains Godot utility functions.
  • files in src/NSClass contain the different NativeScript classes implemented in Haskell.
• Godot files and assets are in game.
