Render on the world problems[SOLVED]

(billy2000) #1

Ok so I have this little problem. The hud of the game follows the camera.And the camera follows player. Everithing worked good and nice but suddenly I got this bug.When the player moves,the camera follows him,but the hud is like rendered 1 frame after,becose it moves after camera 1 frame after the camera actually moves. There is any way to fix this problem? Thx guys :slight_smile: .

I guess you’re doing something like this in your hud entity:

override public function update():void
{
	hud.x = camera.x
	hud.y = camera.y
}

You could either change this to happen inside the render() function instead of update() like this:

override public function render():void
{
	hud.x = camera.x
	hud.y = camera.y
}

I think that should work. Or you could do it a lot more elegantly by not changing the x and y coordinates at all but instead using scrollX and scrollY. So, remove the hud.x = camera.x, hud.y = camera.y from you update() / render() function and instead do this:

private var myhudimage:Image = new Image(...);

public function Hud() 
{
	x = 0;
	y = 0;

	myhudimage.scrollX = 0;
	myhudimage.scrollY = 0;
	
	graphic = (myhudimage);

	super();
}

If you use this scrollX and scrollY property (which every Image, Spritemap… has) the hud/image will always stay on the same position even if your camera moves. Where the value 0 = stick to the screen and the value 1 = move independent from the camera.

I hope this helps.
