Parallax Formula

Hi, I'm making a platform game and I'm using lots of layers so I can give them different parallax.

But if I wanted to put all those backgrounds into one layer and make them parallax with an event, what would the formula be? (Probably would have to use some instance variables like originalX, originalY, ParallaxX and ParallaxY).

Thanks.

You can use LayerToCanvas and CanvasToLayer to convert the position between layers.

Something like (Scrollx-originalx)*0.5 for horizontal parallax. Vertical is similar. Replace 0.5 with the whatever rate you want.
