Hi leon and alan-
Hope you don't mind my butting in...
That's a nice little script. However, it has a flaw; positioning the
cursor over the center of the rotating sprite produces a "cannot divide
by zero" error. One way of amending this is to add a single line:
if x2-x1 = 0 then exit
so the entire script reads:
on exitFrame me
-- get the mouse location
p = the mouseLoc
x1 = p.locH
y1 = p.locV
-- get the sprite location
x2 = (sprite me.spriteNum).locH
y2 = (sprite me. spriteNum). locV
--avoid "cannot divide by zero" error
if x2-x1 = 0 then exit
-- use atan to compute the angle
angle = atan(float(y2-y1)/float(x2-x1))
-- correct the angle
if x1 < x2 then angle = pi()+angle
-- convert the angle to degrees
angle = angle*360.0/(2.0*pi())
-- set sprite rotation
(sprite me.spriteNum).rotation = angle + 90
end
regards,
Clars
