Forums » Help » dynamically create level JSON data

Hello,

I am creating layers programmatically. I'm having trouble understanding how to construct the JSON correctly, specifically how to populate the data[ ] array. Given a tileset how do I know what number to put in each cell of the grid?

I'm looking at the docs here: http://impactjs.com/documentation/class-reference/game#loadlevel

but it does not explain how the numbers map to the tile sheet.

Thanks.

Tileset indices start at 1, with 0 reserved for absence of--read, blank--tile. For example, data for a layer of 4 rows of 4 columns that is void of tiles except for the NW and SE corners which "hold" the first tile in the associated sheet, would be:

data:[
	[1,0,0,0],
	[0,0,0,0],
	[0,0,0,0],
	[0,0,0,1]]
