How to set custom data layer values programmatically in GDScript?

pawlox

Hi,

I'm quite new to Godot. Can anyone tell me if it's possible to set custom data layer values for tiles in GDScript? I'm using Godot 4.3 and TileMapLayers, I see there is function e.g. water_layer.get_cell_tile_data(current_point) and then I can get value with tile_data.get_custom_data('water_depth'), but I don't see any simple way to set tile data for tile at specified coordinates. I need it because I generate my map procedurally. Or maybe it doesn't make sense to do that this way and I should just instantiate custom variable, array with values, in the code?

pawlox For TileMapLayer the update is supposed to be done by implementing _tile_data_runtime_update().

xyz Yeah, I saw this function - so I suppose to implement it in TileMapLayer's script? What if custom data layer value depends on other values generated in other script? 🤔

pawlox Then this script should acquire those values from other scripts. Scripts can exchange data and communicate.

xyz Thanks, I will try to read more on this topic.
