Random move...orient to path?

[jbum]

Here's a rewrite of your code that includes rotation in the direction of movement.

I also changed the method of detecting if you've reached your destination.

code:

---

acceleration = 10;



newpos = function () 

{ 

  ranx = Math.round((Math.random()*250));

  rany = Math.round((Math.random()*250));

};



newpos();



this.onEnterFrame = function() 

{

        // figure direction of movement, relative to current position

        var dx = ranx-this._x;

        var dy = ranx-this._y;

        // figure angle in radians

        var ar = Math.atan2(dy,dx);

        // convert to rotation in degrees

        this._rotation = ar*180/Math.PI;



        this._x += dx/acceleration;

        this._y += dy/acceleration;

        if (Math.abs(dx) < .5 || Math.abs(dy) < .5) {

                newpos();

        }

};
