Forums → Programming Forum → How to make an object point at the mouse?

While I can't fix your code, I can get you one that works for sure, luckly I have answered this one before and I just need some copy and paste

First you'll have to code the angle in degrees your character is shoting, which we'll obtain from atan2, tan from tangent



So code something like this

rotationinradians = Math.atan2(_ymouse - Your Arm/Gun._y , _xmouse - Your Arma/Gun._x);

rotationindegrees = rotationinradians * 180 / Math.PI;

MyObject._rotation = rotationindegrees;

onClipEvent (enterFrame) {
dy = _ymouse-this._y;
dx = _xmouse-this._x;
radianrotation = Math.atan2(dy,dx);
degreerotaition = radianrotation *180 / Math.PI;
this._rotation = degreerotation;
}
Is this what you mean?

The turret goes all weird.
When I move the mouse directly away from it, it spins in random directions.

It might be a problem with the registration point of your movie clip. Make sure the registration point (the little + sign) of your MC is where you want the movieClip to rotate, and not in the center.

Yea, I just tested it with this:

onClipEvent (enterFrame) {
dy = _root._ymouse - this._y;
dx = _root._xmouse - this._x;
radianrotation = Math.atan2(dy,dx);
radianrotation = radianrotation * 180 / Math.PI;
this._rotation = radianrotation;
}

and it worked for me, so make sure your registration point is located in the right position. All you have to do is go inside the movieClip and move the graphic so that the desired pivot point is located in the location you wish to rotate.

Make sure its registration point is set to the center and that it is facing the right. Give it an instance name of âmanâ.

Now place this code on the frame



function convert(radians:Number):Number {
degrees = radians*(180/Math.PI);
return degrees;
}
man.onEnterFrame = function() {
var adjacent:Number = this._x-_xmouse;
var opposite:Number = this._y-_ymouse;
var angle:Number = Math.atan2(opposite, adjacent);
this._rotation = convert(angle);
};

Make sure its registration point is set to the center and that it is facing the right. Give it an instance name of �man�.

Try this code:
onClipEvent (enterFrame) {
_rotation = ((Math.atan2(_root._ymouse-_y,_root._xmouse-_x)/(Math.PI/180))+90
}
Make sure your gun movie clip is facing upwards.

wow i have never heard of this

How to make it don't go upside down when it turns on the other way? I know the script for normal:

onEnterFrame = function (){

But i don't know for OnClipEvent!


Here is the script for OnEnterFrame...

if (this._rotation < -90 || this._rotation > 90)
{
this._xscale = -Math.abs (this._xscale);
this.dir = -1;
this._rotation -= 180;

Don't seem to work with OnClipEvent...
