LimonEngine

LimonEngine is a 3D first person shooter engine, developed as a hobby, to acquire a deeper knowledge of 3D game engine programming.

It can load a wide variety of models and skeletal animations thanks to Assimp, has realtime directional and point lights/shadows and physics.

You can extend the engine capabilities using exposed API, and design maps using the build-in map designer.

You can check out the project web site

For a demonstration, check out the video :

##Building

Dependencies can be installed on Ubuntu 17.10 using:

sudo apt-get install libassimp-dev libbullet-dev libsdl2-dev libsdl2-image-dev libfreetype6-dev libtinyxml2-dev libglew-dev build-essential libglm-dev libtinyxml2-dev

After that, in repository directory mkdir build cd build cmake ../

##Running

Start up:

• Engine take a parameter as path of world to load
• If no parameter passed, falls back to /Data/Maps/World001.xml Note: Save map button in editor mode saves the map to /Data/Maps/CustomWorld001.xml
• Engine tries to load custom trigger extentions as "libcustomTriggers.dll" for windows and "libcustomTriggers.so" for linux. If you use a custom action in a map you have to include these in the library file.

In Application:

• Pressing 0 switches to debug mode, renders physics collision meshes and disconnects player from physics ( flying and passing trough objects)
• Pressing " key switches to editor mode, which allows creating maps.
• Pressing + and - changes mouse sensitivity.
• wasd for walking around and mouse for looking around as usual.

In editor mode:

• Since static and dynamic objects are not generated by same logic, mass settings can't be changed after object creation.
• In animate objects are not allowed to have AI
• You can create animations for doors etc. in editor. For animation creation, time step is 60 for each second.
