I'm not sure of how to even pose the question, but how do you find the best rotation to reach a certain angle?

What I mean is, lets say you have an object facing 75, you want to rotate the angle to 230, how do you determine wether to turn right or left?

function rodir(ang,target)
if wrapvalue(ang+180)<target
direction=-1
else
direction=1
endif
endfunction direction


should work ok, its a function that returns -1 for turn anticlockwise and 1 for turn clockwise, I hope thats some help to you, it uses integer angles btw, it`s not often you need fractional angles, it`s easy enough to alter if needs be, cheers.



if there is one thing I can NOT tolerate, it`s intolerant people.

You can always tell you got a good answer when you look at it and realize that all this time you've been looking at your problem and making it too complex.

Thank you Me! thats a pretty slick function.
