Post your code, the forum is for helping and learning, not just for giving codes.

Ok here is the arrow class

package { import net.flashpunk.Entity; import net.flashpunk.FP import net.flashpunk.utils.Input; import net.flashpunk.utils.Key

public class ARROW extends Entity
{
	[Embed(source = "../New Folder/archer_elfA.png")] public var AR:Class;
	[Embed(source = "../New Folder/archer_elfA2.png")] public var AR2:Class;
	
	protected const ARROW_SPEED:Number = 50;
	protected var _velocityX:Number;
	protected var _velocityY:Number;
	public function ARROW() 
	{
		Image(AR).angle = angle;
	}
	override public function init(x:Number, y:Number, angle:Number):ARROW
	{
		this.x = x;
		this.y = y;
		_velocityX = ARROW_SPEED * Math.cos(angle * FP.RAD);
		_velocityY = ARROW_SPEED * Math.sin(angle * FP.RAD);
		
		return this;
	}
	override public function update():void
	{
		if (Input.pressed(Mouse))
		x += _velocityX * FP.elapsed;
		y += _velocityY * FP.elapsed;
	}
}

} And here is the Entity class

package { import net.flashpunk.Entity; import net.flashpunk.Graphic; import net.flashpunk.graphics.Image; import net.flashpunk.graphics.Stamp; import net.flashpunk.utils.Input; import net.flashpunk.utils.Key; import net.flashpunk.FP;

public class MyEntity extends Entity
{
	[Embed(source = "../New Folder/archer_elf.png")] private var PLAYER:Class;
	[Embed(source = "../New Folder/archer_elf2.png")] private var PLAYERL:Class;
	[Embed(source = "../New Folder/archer_elfENEN.png")] private var PLAYERE:Class;
	public function MyEntity() 
	{
		graphic = new Image(PLAYER);
	}
	override public function update():void
	{
		if (Input.mousePressed())
		{
			
		}
		if (Input.pressed(Key.A))
		{
			graphic = new Image(PLAYERL) //Player facing left
		}
		if (Input.pressed(Key.D))
		{
			graphic = new Image(PLAYER)// Player facing right
		}
		if (Input.check(Key.D)) { x += 3 };
		if (Input.check(Key.A)) { x -= 3 };
		if (Input.check(Key.W)) { y -= 3 };
		if (Input.check(Key.S)) { y += 3 };
	}
}

}

OK, a few things:

  • Your ARROW class never angle against the mouse, for that use FP.angle and the world properties mouseX and mouseY

  • Your ARROW class never has the graphic set.

  • Your ARROW class has the same graphics as the Player

  • You have set the Input check for the mouse inside the ARROW itself, but what you probably want to do is this:

      override public function update():void
  {
    if (Input.pressed(Mouse))
    x += _velocityX * FP.elapsed;
    y += _velocityY * FP.elapsed;
  }

Should be this:

    override public function update():void
    {
      x += _velocityX * FP.elapsed;
      y += _velocityY * FP.elapsed;
    }

And what you probably want to do is this on your MyEntity class:

if (Input.mousePressed())
{

}

Should be that:

if (Input.mousePressed())
{
  this.world.add(new ARROW());
}

So should i also put the velocity and speed in the world class to? The graphics are different just the names are just slightly different.

No need for that, you can always get the current world with this.world so you can make all the calculation inside your ARROW class.

And sorry, now I saw that it have an “A” as suffix in the image.

Ok thanks for your help.
