How do I use a script to change a tile in a tilemap?

Hi all,

I am trying to use this script to change a tile in my tilemap from whatever it is to tileID "123"

const tm = runtime.objects.Tilemap.getFirstInstance();

const player = runtime.objects.Player.getFirstInstance();

tm.setTileAt(player.x,player.y,123)

I thought this would be the way to script this but its not updating the tilemap.

What am I missing here?

Thanks in advance!

const player = runtime.objects.Player.getFirstInstance();

tm.setTileAt(player.x,player.y,123)

player.x and player.y are layout coordinates. You need to convert them to tilemap coordinates. There are expressions like PositionToTileX/Y, but looks like there are no similar methods in the scripting API.
