Access tile by tilemap index

[BenClarkson]

Ok. I'm trying to build one way platforms using tilemaps and I don't quite know how to access all the tiles of a type (say, id '5' from the json) and give it custom properties (like tile.collideLeft = false). This would also be great for setting tile classes, like water, ladders, and other things.

Cool! Thanks.

I solved it!
 

state.prototype.setOneWayTiles = function (map) {

map.forEach(function(tile){

if (tile.index == the tile index you're looking for) {

set tile properties;} } 

)

}
