Using LayerToCanvas

Hello!

I've been struggling to wrap my head around LayerToCanvas and CanvasToLayer, how they work and how to use them. I've managed to hunt down a few examples that were both great but I couldn't take much away from them and still don't fundamentally understand how they are supposed to function.

I have a simple setup in mind:

1) A sprite spawns an explosion on a standard layer that scrolls rapidly with a 100% parallax rate

2) The explosion immediately becomes attached to the top layer which has 0% parallax

The intended outcome should be an explosion that doesn't scroll with the camera.

If anyone can help with this I'd be very grateful.

Say, layer "Game" has 100% parallax, and layer "HUD" 0% parallax.

Spawn explosion on layer "Game" at (500,200)

explosion Set X to CanvasToLayerX("HUD", LayerToCanvasX("Game", explosion.x, explosion.y), LayerToCanvasY("Game", explosion.x, explosion.y))

explosion Set Y to CanvasToLayerY("HUD", LayerToCanvasX("Game", explosion.x, explosion.y), LayerToCanvasY("Game", explosion.x, explosion.y))


Move explosion to layer "HUD"

Thank you, that worked perfectly!
