circumference?...

[DeadRiver]

I'm trying to figure out how to place a bullet mc at the tip of my gun depending on its rotation...?

[newblack]

x = circle's center + cos( angle ) * radius;
y = circle's center + sin( angle ) * radius;
where angle is in radians
ps: circumference is the length of a circle's perimeter.

I've set it up like this...

ammo._x = _root.gun._x + Math.cos(_root.gun._rotation) * 50;
ammo._y = _root.gun._y + Math.sin(_root.gun._rotation) * 50;

and it's not working correctly? what did I do wrong?

the guns x and y would be the center, and the gun is 50 pixels long so 50 would be the radius right?

MovieClip's _rotation property is in degrees, not radians. So you need to convert to radians:
radians = degrees * pi / 180

oh snap thats right ty ty!
works perfectly!

I think tangent would be better to use. and use ATAN2() to get degrees
