 				Sets the tile indentifiers for the cell on layer [param layer] at coordinates [param coords]. Each tile of the [TileSet] is identified using three parts:
 				- The source identifier [param source_id] identifies a [TileSetSource] identifier. See [method TileSet.set_source_id],
-				- The atlas coordinates identifier [param atlas_coords] identifies a tile coordinates in the atlas (if the source is a [TileSetAtlasSource]. For [TileSetScenesCollectionSource] it should be 0),
+				- The atlas coordinates identifier [param atlas_coords] identifies a tile coordinates in the atlas (if the source is a [TileSetAtlasSource]. For [TileSetScenesCollectionSource] it should always be [code]Vector2i(0, 0)[/code]),
 				- The alternative tile identifier [param alternative_tile] identifies a tile alternative the source is a [TileSetAtlasSource], and the scene for a [TileSetScenesCollectionSource].
+				If [param source_id] is set to [code]-1[/code], [param atlas_coords] to [code]Vector2i(-1, -1)[/code] or [param alternative_tile] to [code]-1[/code], the cell will be erased. An erased cell gets [b]all[/b] its identifiers automatically set to their respective invalid values, namely [code]-1[/code], [code]Vector2i(-1, -1)[/code] and [code]-1[/code].
