- Brush
- A brush is the name given to any
3D object with volume. Most brushes start in
basic shapes - Cube, cylinder, wedge, and spike -
and are grouped, carved, or in other ways edited
to create more complex brushes like stairs,
pillars, arches, etc. Brushes can also be
non-solid types such as water, slime, or lava.
The basic structure of a level is designed
entirely of brushes.
-
- Entity
- An entity is pretty much
everything else in the game that isn't a brush.
Weapons, monsters, lights, player starts, etc..
are all entities. There's also a special sort of
entity that combines with a brush in order to
make it perform a function in the game: doors,
teleporters, lifts etc. Just to make things
confusing they're also called entities.
-
- Texture
- Textures are the 'paintings' on
the brushes that make it look like brick, wood,
or stone etc. Some textures are animated (the sky
or water textures for example), and some give off
light (such as some of the buttons.)
-
- Face
- A face is one side of a brush.
Brushes will have 5 or more faces. A cube has 6
faces (Think of dice) Each face of a brush can
have a different texture. A wedge would have 5
faces. Cylinders and Spikes can have many faces.
