The question is, is your psuedo random nume generator trhead safe code? If
not, semaphore it.

The seed we are assuming is absed o na fixed unchanging quantity sucha s
the coords of the room. Thsi is why we are using the psudeo random (besides
the fact tha there IS no true random on a computer, just psuedo random
generators. Most people fake it by seeding the psuedorandom library
function off of soemthing reasobnably unpredictable and quickly changing,
like up time in ticks.)
