Now that you know there is an atan() function, you'll eventually work
out the routine for getting the angle from one sprite to another. The
routine is usually about 10 lines long or so, but there's a way of
using atan() that will cut the routine down to one line:
angle = atan(p2[1]-p1[1],p2[2]-p1[2])
p1 and p2 would be the locs of the two sprites, and the resulting
angle would be in radians. You can convert that to degrees by
dividing by Pi and multiplying by 180. The whole routine to make a
sprite turn towards the mouse location would be:
on prepareframe me
p1 = the mouseloc
p2 = sprite(me.spritenum).loc
sprite(me.spritenum).rotation = 360-(atan(p2[1]-p1[1],p2[2]-p1[2]))/pi*180
end
This script would be attached to the sprite that needs to turn.
