I was going to try to rotate a sprite, so i made a definition that gives the angle between two points, but i discovered that i can't rotate a sprite, and to not just delete this useful(for somebody else) definition i am posting it here.
Code:
def get_ang(sx,sy,tx,ty)
if tx < sx
d = sy
sy = ty
ty = d
end
pi = 3.141592654
rad = pi/180
grau = (Math.atan2( -(tx - sx), -(ty - sy))/rad).abs.ceil
grau += 180 if tx < sx
return grau
end
