`getBounds` get wrong coordinate

Recommended Posts

In my code, I use center as 0, 0.

My other coordinate are all right, but when I use `getBounds` to get a curve's bound, the return value is incorrect.

It seems the x,y is relative to top-left instead of center.


Why? How can I get the correct coordinate?

Using the top left corner as the origin is common for 2D computer graphics, but you can convert the bounds like this:

var bounds = sprite.getBounds();

bounds.x -= renderer.width  / 2;
bounds.y -= renderer.height / 2;
