They are stuck in place maybe because you are not moving them at all? If you are then please show me where. Try adding to the turret's enter frame event the following code:
for (var a:int = 0; bullets.length > a ; a++)
{
var temp:MovieClip;
temp = bullets[a] as Bullet;
var vel:Point = new Point();
vel.x = temp.target.x-temp.x;
vel.y = temp.target.y-temp.y;
vel.normalize(4);
temp.x += vel.x;
temp.y += vel.y;
}
And make an as file for the Bullet Class and add this:
package
{
import flash.geom.Point;
public class Bullet extends MovieClip
{
public var target:Point = new Point();
public function Bullet()
{
target.x = stage.mouseX;
target.y = stage.mouseY;
}
}
}
