It's not really simple math

NPC Code:


radangle = random(0,2*3.14);

dx = cos(radangle);

dy = -sin(radangle);



move dx*5,dy*5,5,16;


3.14 = pi
It's dy = -sin(radangle) because when
the angle is pi/2 (90 degrees) then it should
move up, so sin(90) = 1 needs to move the
npc up which means y needs to be decreased
