View source for 001af59c - 001af6d4

 Parameters : r4 = [001af3dc val2] = (0xa8000/[Attacker to Target distance] - 64)
              r5 = [V2] = 0x76*sin([Attack's angle])*4096    (Angle from 0x801b8b70 / 801b8b70)
 *Thoses values came from the 001afb38 - 001afd8c routine
 
 Returns r2 = Some maths that i don't understand anymore
 (i give up on this one, tired off all this maths... maths are the only thing here. Nothing stored)
