How to implement with World Generator

[ilomon10]

How can I implement this TileMapDual with a world generator, such as using procedural generation?
I tried implementing it with procedural generation, but when I call set_cell or draw_cell, it doesn’t seem to work.

Hi there, please test beforehand that you can manually draw and remove individual cells with draw_cell. If it doesn't work, an example would be great

hello @pablogila, manually draw is working smoothly. but when i try to implement with programaticly it does not show anything.

also the placed tile cannot be erase after duplicate/copy the TileMapDual node.

I encountered a similar issue when attempting to implement chunk loading and unloading using TileMapDual. Whenever I directly called draw_cell on the main thread to update the map, it took around 16-19ms to update a 16x16 chunk, which made the physics frame very long and caused the scene to lag. I tried to address this by using multithreading, but ran into some difficulties. It seems that TileMapDual does not draw tiles correctly when not added to the scene tree, which was frustrating.

hello @ilomon10 could you please share a small example to check it?
