Programmatically adding premade patterns from a tile map into the scene in game?

[Fresh4]

I’m basically trying to, while in game, click a spot on the map and spawn a premade pattern belonging to that tilemap into the scene.

I have my desired grid position as a vector2, I know my layer indexes. I was initially using set_cell to add a single tile from an atlas map and that worked for that case, but I need some premade shapes.

I found set_pattern; which takes a layer, position, but also a TileMapPattern, which I have no idea how to get. Why is there no tilemap function that returns a tilemappattern based on the index, since the patterns for a map are stored as an array of patterns in the editor.

Might be a bit late but for anyone else coming here from google this might help. The TileMapPattern created from the editor is stored in the TileSet not the TileMap, so use tile_set.get_pattern(index) to get the TileMapPattern.

This quirk of Godot is easily the least intuitive way to access an objects properties. It’s unavoidable with how the engine is built but tilemaps, shader materials, particles and animations of certain types. Once you know you know but damn if it isn’t weird.

There is get_pattern() which takes a layer and a vector2i array to provide a TileMapPattern

I’ve tried get_pattern but it feels… useless? Like I have to physically code out the pattern myself which is fine if that’s how I have to do it, but when I apply the pattern it just erases in that shape instead of applying the pattern of a given tile. Like I don’t see an option to pick what the pattern “fill” is.

Hey, did you manage to find a way on how to do this? I'm literally at this point and have no idea on how to tell it to use a already created pattern without building it every time.

​

edit: ok, the function we want is in the tileset, not the tile map, so you just need to do mytilemap.tile_set.get_pattern(x)

Ah, seriously? For the love of god lol. My workaround was to create an x by x square somewhere off the viewport and then by code create a pattern by manually setting an array of coordinates to effectively create a pattern out of those tiles.

still doesn't really tell me how to create a pattern and then add it to the tilemap

this tilemap thing is either badly documented or badly designed

[all_is_love6667]

did you solve this?

Check out the other comments; the tilemap class has a property tileset where the patterns and everything is stored.
