Rotating an entity... problems

(John Andersson) #1

Okay, so I have an entity I want to use a pixelmask with. Now, I also want to rotate the entity. I know flashpunk can’t handle rotating hitboxes, but that’s okay, since I basically have a ball which is rolling. I needed to use centerorigin to set the rotation point at the middle of the ball, but now the hitbox is way off. I tried originX and originY, but it doesn’t work.

Have a look here. I’m not sure if the last code works 'couse noone said so but the tread is about this.

Isn’t that about hitboxes? How do I make the ball rotate continuously?

So you only want to rotate the graphic? If that’s so, what graphic are you using? (i mean the class, like Image, Stamp, etc.)

Yeah, I’m using a spritemap :slight_smile:

I would do this:

In the contructor

private var sprite:Spritemap;
private var target:BitmapData;
private var renderer:Image;

//set spritemap

target = new BitmapData(size, size, true, 0);
renderer = new Image(target);
renderer.centerOrigin();
graphic = renderer;

and then in the render function:

override public function render():void
{
	target.fillRect(target.rect, 0);
	sprite.render(target, FP.zero, FP.zero);
	super.render();
}

All the modifications you do to renderer should modify the result as you spect.
