Lemma is an immersive first-person parkour game. Every parkour move has the potential to modify the environment. Surfaces pop in and out of existence at will.
What is this?
All the code and some of the assets for Lemma are open source. Everything you need to create your own single-player campaign is there, including a level editor.
Is it good code?
Not really. The project started in 2010 and served as a test bed for a lot of hairbrained ideas I had back then. Consider it an example of what not to do.
- Install Microsoft Visual C# 2015 and XNA Game Studio 4.0 Refresh.
- Clone the repository.
- Set the active solution configuration
- Build and run the solution.
- On the main menu, hit "switch to edit mode" to open the level editor.
See the Official level editor guide.
To make or edit models, you'll need Blender. The asset pipeline has been tested with Blender 2.70a. Here's how to get started:
- Install Blender 2.70a.
- Find the file
- Copy the file into the Blender program folder under
2.70\scripts\addons\io_scene_fbx(it should replace an existing file).
- Open Blender and make sure the FBX export addon is enabled.
- Open a .blend file and select File -> Export -> Autodesk FBX.
- Use the following export settings for animations:
The following textures are adapted from CGTextures source images, and are therefore only made available here for modding purposes:

To use them for your own purposes, you must re-download them from CGTextures and follow their usage guidelines.
