Overview:
|
|
Perhaps the most cryptic datum in the lighting engine, there are four of these at the corners of every turf.
|
|
Any two turfs that share a corner will also have the same lightpoint. Because of the nature of the icons used,
|
|
light is shown at the corner of the turf rather than in the middle, necessitating some way to keep track of what
|
|
icon state to use.
|
|
|
|
Class Vars:
|
|
x, y, z - The position of the lightpoint. x and y will usually be expressed in terms of 0.5 due to its location on the corner.
|
|
|
|
NE, NW, SE, SW - The turfs that are in these directions relative to the lightpoint.
|
|
|
|
cached_value - A cached value of max_value().
|
|
|
|
Class Procs:
|
|
max_value()
|
|
The maximum of the light amounts on the four turfs of this light point.
