Node for 2D tile-based maps.

</brief_description>
|
|
<description>
|
|
Node for 2D tile-based maps. A [TileMapLayer] uses a [TileSet] which contain a list of tiles which are used to create grid-based maps. Unlike the [TileMap] node, which is deprecated, [TileMapLayer] has only one layer of tiles. You can use several [TileMapLayer] to achieve the same result as a [TileMap] node.
|
|
For performance reasons, all TileMap updates are batched at the end of a frame. Notably, this means that scene tiles from a [TileSetScenesCollectionSource] may be initialized after their parent. This is only queued when inside the scene tree.
|
|
To force an update earlier on, call [method update_internals].

Called with a [TileData] object about to be used internally by the [TileMapLayer], allowing its modification at runtime.
|
|
This method is only called if [method _use_tile_data_runtime_update] is implemented and returns [code]true[/code] for the given tile [param coords].
|
|
[b]Warning:[/b] The [param tile_data] object's sub-resources are the same as the one in the TileSet. Modifying them might impact the whole TileSet. Instead, make sure to duplicate those resources.
|
|
[b]Note:[/b] If the properties of [param tile_data] object should change over time, use [method notify_runtime_tile_data_update] to notify the [TileMapLayer] it needs an update.

<description>
|
|
Returns a [Vector2i] array with the positions of all cells containing a tile. Tiles may be filtered according to their source ([param source_id]), their atlas coordinates ([param atlas_coords]), or alternative id ([param alternative_tile]).
|
|
If a parameter has its value set to the default one, this parameter is not used to filter a cell. Thus, if all parameters have their respective default values, this method returns the same result as [method get_used_cells].

Returns for the given coordinates [param coords_in_pattern] in a [TileMapPattern] the corresponding cell coordinates if the pattern was pasted at the [param position_in_tilemap] coordinates (see [method set_pattern]). This mapping is required as in half-offset tile shapes, the mapping might not work by calculating [code]position_in_tile_map + coords_in_pattern[/code].

Returns the centered position of a cell in the [TileMapLayer]'s local coordinate space. To convert the returned value into global coordinates, use [method Node2D.to_global]. See also [method local_to_map].
|
|
[b]Note:[/b] This may not correspond to the visual position of the tile, i.e. it ignores the [member TileData.texture_origin] property of individual tiles.

<method name="notify_runtime_tile_data_update">

|

<description>
|
|
Notifies the [TileMapLayer] node that calls to [method _use_tile_data_runtime_update] or [method _tile_data_runtime_update] will lead to different results. This will thus trigger a [TileMapLayer] update.
|
|
[b]Warning:[/b] Updating the [TileMapLayer] is computationally expensive and may impact performance. Try to limit the number of calls to this function to avoid unnecessary update.
|
|
[b]Note:[/b] This does not trigger a direct update of the [TileMapLayer], the update will be done at the end of the frame as usual (unless you call [method update_internals]).

<description>
|
|
Sets the tile identifiers for the cell 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 coordinate 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 in the atlas (if 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].

Update all the cells in the [param cells] coordinates array so that they use the given [param terrain] for the given [param terrain_set]. If an updated cell has the same terrain as one of its neighboring cells, this function tries to join the two. This function might update neighboring tiles if needed to create correct terrain transitions.
|
|
If [param ignore_empty_terrains] is true, empty terrains will be ignored when trying to find the best fitting tile for the given terrain constraints.
|
|
[b]Note:[/b] To work correctly, this method requires the [TileMapLayer]'s TileSet to have terrains set up with all required terrain combinations. Otherwise, it may produce unexpected results.

Update all the cells in the [param path] coordinates array so that they use the given [param terrain] for the given [param terrain_set]. The function will also connect two successive cell in the path with the same terrain. This function might update neighboring tiles if needed to create correct terrain transitions.
|

If [param ignore_empty_terrains] is true, empty terrains will be ignored when trying to find the best fitting tile for the given terrain constraints.

Triggers a direct update of the [TileMapLayer]. Usually, calling this function is not needed, as [TileMapLayer] node updates automatically when one of its properties or cells is modified.
|
|
However, for performance reasons, those updates are batched and delayed to the end of the frame. Calling this function will force the [TileMapLayer] to update right away instead.
|
|
[b]Warning:[/b] Updating the [TileMapLayer] is computationally expensive and may impact performance. Try to limit the number of updates and how many tiles they impact.

The [TileMapLayer]'s quadrant size. A quadrant is a group of tiles to be drawn together on a single canvas item, for optimization purposes.

The quadrant size does not apply on a Y-sorted [TileMapLayer], as tiles are be grouped by Y position instead in that case.
