• There are layers, each layer can be displayed and/or cause collisions (so you might have a object with a medium poly count to draw in one displayed layer, and with low poly count in a layer causing collisions, as too many collision faces will cause Flyin' to be slow).
• Layers might be static or animated. Animated layers might contain single frame's meshes or will use default animations: Move in a direction, Move in a direcion and back.
• Layer animations can be looped or triggered (caused by the fly to be in a specific area).
• Green and Red Spheres are not part of layers, they will get generated on-the-fly (hey, a pun!). You need only to specify its position in level converter.
• Each level has a starting point, also being set by the level converter.
• Each level has a clear color drawn in areas without faces (because of sight). See for example the cave level (gray) and the attic (black).

• Moving: Move with a speed in a direction, reset after a number of frames
• Vibrating: Move with a speed in a direction, change direction after a specific distance (width); width can be configured for every dimension (x,y,z).
• Trigger: Like Moving, but starts after the fly enters a Trigger Area, and won't reset; the animation just stops after the time.
• Animated: Use animation with single frames (naming like the example level: as blender does it when exporting wavefront animation)
• Animated-Trigger: like Animated, but starting when the fly enters a Trigger Area, and won't loop.
