FILE: psd2level.jsx
Version: 1.0 (kinda finished)

This is an extremely simple script which save each layer as a type
with an x and y position.
This script generates a text file in a folder called "Output", which must be in the same
folder as the .psd

if you have a layer named tFloor, this is how it is saved: 

setSpriteVisible ( tWalls[1].sprID, 1)
tWalls[1].isActive = 1
setSpritePosition(tWalls[1].sprID, 130, 200)


Of course, it would first need to exist as a type in your game:

type floorType
	sprID as integer
	isActive as integer
endtype

Global tFloor as floorType[500]

global floorImg as integer
floorImg = LoadImage ("floor.png")

for i = 1 to tFloor.length
	tFloor[i].sprID = createSprite(floorImg)
	tFloor[i].isActive = FALSE
	setSpriteVisible (tFloor[i].sprID, FALSE)
next


Layers with // in their name are ignored.
