[Door] Settings for doors in an arena.
Datatype: Hundredths of seconds.
How often doors attempt to switch their state.
Each bit of this field determines whether its represented door is open or not. The 8 bits, from left to right, represent the 8 door tiles in the tileset, from left to right.
- -2 = all doors completely random
- -1 = weighted random (some doors open more often than others)
- 0-255 = fixed doors (1 bit of byte for each door specifying whether it is open or not)
