Integer value I think you mean.

Mobile phones tho

quick question, how can i, for example, make a door, or other interactive object on the map? Or how can i change the tile image for a tile that was inserted on an object layer? ty

edit: actually is there any way i can even update the proprieties of the layer/object layer?

If you use the Box2D plugin, you can create a sensor object that performs some action when you collide with it. Set the properties collidable = true and sensor = true. If you use a different plugin, or your own collision code, you can code that in manually.

You can swap out a tile using Map:swapTile(current_tile_instance, new_tile_object)

ok thanks. So i cant change a propriety of a tile while running the program?
Edit: this is because i tried to change it while running, and it wont update... I added the map:update(), so idk why it wont change.

Yes and no. You can't change the properties of an individual instance of a tile, but you can change the properties of a tile, and all of its instances. Map.tiles[gid].properties is what you're after.

but if i have multiple doors, and i only want one to open, i cant use the way you told me now, it would change the properties of all the doors using that tile, no?

You don't want to use tiles for such things. Use tile objects in Tiled to place individual door objects, and then update them individually in love.

update them with Map.tiles[gid].properties?
or with swap? im so confused ;-;

Map:swapTile is used to replace a tile in a layer with a different one. Map.tiles[gid] is a tile object that you can modify so that all tile instances will be updated (exept for the graphic, you need to use swapTile for that since sprite batching acts like a cache).
