How to get distance between two objects on the different layers if one layer is without parallax and 100% scale (UI layer) while other layer is with parallax and scaled

I suppose one way would be to use these system expressions.

CanvasToLayerX(layer, x, y)

CanvasToLayerY(layer, x, y)

LayerToCanvasX(layer, x, y)

LayerToCanvasY(layer, x, y)
Cx = LayerToCanvasX(sprite.layer, sprite.x, sprite.y) Cy = ... Lx = CanvasToLayerX(sprite2.layer, cx, cy) Ly = ... D = distance(sprite2.x,sprite2.y, lx,ly)

Another is to come up with the formula to do the parallax. It may end up being simpler but may take a bit of fiddling to get it right.

Off the top of my head if there’s no rotation then

X2 = ((x-scrollx)*parallax+scrollx)*scale

Could be a possible start

this method is working, with a little addition, we got add the scale of the layer to the the "canvas to layer" value

layer's scale is 0.9 so, I got to multiply the value by 1.11

Thank you a lot
