Const DeadSpaceRadius = 50 If Sqr( ( x- w )^2 + ( y-h )^2 ) > DeadSpaceRadius TurnEntityEtc... Endif
Sqr() just slows things down (not that it really matters in this usage).
This does the exact same thing, just a wee bit faster.
const DeadSpaceRadius = 50 If ( x- w )^2 + ( y-h )^2 > DeadSpaceRadius*DeadSpaceRadius TurnEntityEtc... Endif
