TileMap

Inherits: Node2D < CanvasItem < Node < Object

Node for 2D tile-based maps.

Description

Node for 2D tile-based maps. Tilemaps use a TileSet which contain a list of tiles which are used to create grid-based maps. A TileMap may have several layers, layouting tiles on top of each other.

Properties

Methods

Signals

changed ( )

Emitted when the TileSet of this TileMap changes.

Enumerations

enum VisibilityMode:

VisibilityMode VISIBILITY_MODE_DEFAULT = 0

Use the debug settings to determine visibility.

VisibilityMode VISIBILITY_MODE_FORCE_HIDE = 2

Always hide.

VisibilityMode VISIBILITY_MODE_FORCE_SHOW = 1

Always show.

Property Descriptions

int cell_quadrant_size = 16

• void set_quadrant_size ( int value )

• int get_quadrant_size ( )

The TileMap’s quadrant size. Optimizes drawing by batching, using chunks of this size.

bool collision_animatable = false

• void set_collision_animatable ( bool value )

• bool is_collision_animatable ( )

If enabled, the TileMap will see its collisions synced to the physics tick and change its collision type from static to kinematic. This is required to create TileMap-based moving platform.

Note: Enabling collision_animatable may have a small performance impact, only do it if the TileMap is moving and has colliding tiles.

VisibilityMode collision_visibility_mode = 0

• void set_collision_visibility_mode ( VisibilityMode value )

• VisibilityMode get_collision_visibility_mode ( )

Show or hide the TileMap’s collision shapes. If set to VISIBILITY_MODE_DEFAULT, this depends on the show collision debug settings.

VisibilityMode navigation_visibility_mode = 0

• void set_navigation_visibility_mode ( VisibilityMode value )

• VisibilityMode get_navigation_visibility_mode ( )

Show or hide the TileMap’s navigation meshes. If set to VISIBILITY_MODE_DEFAULT, this depends on the show navigation debug settings.

TileSet tile_set

• void set_tileset ( TileSet value )

• TileSet get_tileset ( )

The assigned TileSet.

Method Descriptions

void _tile_data_runtime_update ( int layer, Vector2i coords, TileData tile_data ) virtual

Called with a TileData object about to be used internally by the TileMap, allowing its modification at runtime.

This method is only called if _use_tile_data_runtime_update is implemented and returns true for the given tile coords and layer.

Warning: The 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.

Note: If the properties of tile_data object should change over time, use force_update to trigger a TileMap update.

bool _use_tile_data_runtime_update ( int layer, Vector2i coords ) virtual

Should return true if the tile at coordinates coords on layer layer requires a runtime update.

Warning: Make sure this function only return true when needed. Any tile processed at runtime without a need for it will imply a significant performance penalty.

void add_layer ( int to_position )

Adds a layer at the given position to_position in the array. If to_position is negative, the position is counted from the end, with -1 adding the layer at the end of the array.

void clear ( )

Clears all cells.

void clear_layer ( int layer )

Clears all cells on the given layer.

void erase_cell ( int layer, Vector2i coords )

Erases the cell on layer layer at coordinates coords.

void fix_invalid_tiles ( )

Clears cells that do not exist in the tileset.

void force_update ( int layer=-1 )

Triggers an update of the TileMap. If layer is provided, only updates the given layer.

Note: The TileMap node updates automatically when one of its properties is modified. A manual update is only needed if runtime modifications (implemented in _tile_data_runtime_update) need to be applied.

Warning: Updating the TileMap is computationally expensive and may impact performance. Try to limit the number of updates and the tiles they impact (by placing frequently updated tiles in a dedicated layer for example).

int get_cell_alternative_tile ( int layer, Vector2i coords, bool use_proxies=false ) const

Returns the tile alternative ID of the cell on layer layer at coords. If use_proxies is false, ignores the TileSet‘s tile proxies, returning the raw alternative identifier. See TileSet.map_tile_proxy.

Vector2i get_cell_atlas_coords ( int layer, Vector2i coords, bool use_proxies=false ) const

Returns the tile atlas coordinates ID of the cell on layer layer at coordinates coords. If use_proxies is false, ignores the TileSet‘s tile proxies, returning the raw alternative identifier. See TileSet.map_tile_proxy.

int get_cell_source_id ( int layer, Vector2i coords, bool use_proxies=false ) const

Returns the tile source ID of the cell on layer layer at coordinates coords. Returns -1 if the cell does not exist.

If use_proxies is false, ignores the TileSet‘s tile proxies, returning the raw alternative identifier. See TileSet.map_tile_proxy.

TileData get_cell_tile_data ( int layer, Vector2i coords, bool use_proxies=false ) const

Returns the TileData object associated with the given cell, or null if the cell does not exist or is not a TileSetAtlasSource.

If use_proxies is false, ignores the TileSet‘s tile proxies, returning the raw alternative identifier. See TileSet.map_tile_proxy.

func get_clicked_tile_power():
    var clicked_cell = tile_map.local_to_map(tile_map.get_local_mouse_position())
    var data = tile_map.get_cell_tile_data(0, clicked_cell)
    if data:
        return data.get_custom_data("power")
    else:
        return 0

Vector2i get_coords_for_body_rid ( RID body )

Returns the coordinates of the tile for given physics body RID. Such RID can be retrieved from KinematicCollision2D.get_collider_rid, when colliding with a tile.

int get_layer_for_body_rid ( RID body )

Returns the tilemap layer of the tile for given physics body RID. Such RID can be retrieved from KinematicCollision2D.get_collider_rid, when colliding with a tile.

Color get_layer_modulate ( int layer ) const

Returns a TileMap layer’s modulate.

String get_layer_name ( int layer ) const

Returns a TileMap layer’s name.

int get_layer_y_sort_origin ( int layer ) const

Returns a TileMap layer’s Y sort origin.

int get_layer_z_index ( int layer ) const

Returns a TileMap layer’s Z-index value.

int get_layers_count ( ) const

Returns the number of layers in the TileMap.

RID get_navigation_map ( int layer ) const

Returns the NavigationServer2D navigation map RID currently assigned to the specified TileMap layer.

By default the TileMap uses the default World2D navigation map for the first TileMap layer. For each additional TileMap layer a new navigation map is created for the additional layer.

In order to make NavigationAgent2D switch between TileMap layer navigation maps use NavigationAgent2D.set_navigation_map with the navigation map received from get_navigation_map.

Vector2i get_neighbor_cell ( Vector2i coords, CellNeighbor neighbor ) const

Returns the neighboring cell to the one at coordinates coords, identified by the neighbor direction. This method takes into account the different layouts a TileMap can take.

TileMapPattern get_pattern ( int layer, Vector2i[] coords_array )

Creates a new TileMapPattern from the given layer and set of cells.

Vector2i[] get_surrounding_cells ( Vector2i coords )

Returns the list of all neighbourings cells to the one at coords.

Vector2i[] get_used_cells ( int layer ) const

Returns a Vector2i array with the positions of all cells containing a tile in the given layer. A cell is considered empty if its source identifier equals -1, its atlas coordinates identifiers is Vector2(-1, -1) and its alternative identifier is -1.

Vector2i[] get_used_cells_by_id ( int layer, int source_id=-1, Vector2i atlas_coords=Vector2i(-1, -1), int alternative_tile=-1 ) const

Returns a Vector2i array with the positions of all cells containing a tile in the given layer. Tiles may be filtered according to their source (source_id), their atlas coordinates (atlas_coords) or alternative id (alternative_tile).

If a parameter has it’s value set to the default one, this parameter is not used to filter a cell. Thus, if all parameters have their respective default value, this method returns the same result as get_used_cells.

A cell is considered empty if its source identifier equals -1, its atlas coordinates identifiers is Vector2(-1, -1) and its alternative identifier is -1.

Rect2i get_used_rect ( )

Returns a rectangle enclosing the used (non-empty) tiles of the map, including all layers.

bool is_layer_enabled ( int layer ) const

Returns if a layer is enabled.

bool is_layer_y_sort_enabled ( int layer ) const

Returns if a layer Y-sorts its tiles.

Vector2i local_to_map ( Vector2 local_position ) const

Returns the map coordinates of the cell containing the given local_position. If local_position is in global coordinates, consider using Node2D.to_local before passing it to this method. See also map_to_local.

Vector2i map_pattern ( Vector2i position_in_tilemap, Vector2i coords_in_pattern, TileMapPattern pattern )

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

Vector2 map_to_local ( Vector2i map_position ) const

Returns the centered position of a cell in the TileMap’s local coordinate space. To convert the returned value into global coordinates, use Node2D.to_global. See also local_to_map.

Note: This may not correspond to the visual position of the tile, i.e. it ignores the TileData.texture_origin property of individual tiles.

void move_layer ( int layer, int to_position )

Moves the layer at index layer to the given position to_position in the array.

void remove_layer ( int layer )

Removes the layer at index layer.

void set_cell ( int layer, Vector2i coords, int source_id=-1, Vector2i atlas_coords=Vector2i(-1, -1), int alternative_tile=0 )

Sets the tile indentifiers for the cell on layer layer at coordinates coords. Each tile of the TileSet is identified using three parts:

• The source identifier source_id identifies a TileSetSource identifier. See TileSet.set_source_id,

• The atlas coordinates identifier atlas_coords identifies a tile coordinates in the atlas (if the source is a TileSetAtlasSource). For TileSetScenesCollectionSource it should always be Vector2i(0, 0)),

• The alternative tile identifier alternative_tile identifies a tile alternative in the atlas (if the source is a TileSetAtlasSource), and the scene for a TileSetScenesCollectionSource.

If source_id is set to -1, atlas_coords to Vector2i(-1, -1) or alternative_tile to -1, the cell will be erased. An erased cell gets all its identifiers automatically set to their respective invalid values, namely -1, Vector2i(-1, -1) and -1.

void set_cells_terrain_connect ( int layer, Vector2i[] cells, int terrain_set, int terrain, bool ignore_empty_terrains=true )

Update all the cells in the cells coordinates array so that they use the given terrain for the given 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 ignore_empty_terrains is true, empty terrains will be ignored when trying to find the best fitting tile for the given terrain constraints.

Note: To work correctly, this method requires the TileMap’s TileSet to have terrains set up with all required terrain combinations. Otherwise, it may produce unexpected results.

void set_cells_terrain_path ( int layer, Vector2i[] path, int terrain_set, int terrain, bool ignore_empty_terrains=true )

Update all the cells in the path coordinates array so that they use the given terrain for the given 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 ignore_empty_terrains is true, empty terrains will be ignored when trying to find the best fitting tile for the given terrain constraints.

Note: To work correctly, this method requires the TileMap’s TileSet to have terrains set up with all required terrain combinations. Otherwise, it may produce unexpected results.

void set_layer_enabled ( int layer, bool enabled )

Enables or disables the layer layer. A disabled layer is not processed at all (no rendering, no physics, etc…).

If layer is negative, the layers are accessed from the last one.

void set_layer_modulate ( int layer, Color modulate )

Sets a layer’s color. It will be multiplied by tile’s color and TileMap’s modulate.

If layer is negative, the layers are accessed from the last one.

void set_layer_name ( int layer, String name )

Sets a layer’s name. This is mostly useful in the editor.

If layer is negative, the layers are accessed from the last one.

void set_layer_y_sort_enabled ( int layer, bool y_sort_enabled )

Enables or disables a layer’s Y-sorting. If a layer is Y-sorted, the layer will behave as a CanvasItem node where each of its tile gets Y-sorted.

Y-sorted layers should usually be on different Z-index values than not Y-sorted layers, otherwise, each of those layer will be Y-sorted as whole with the Y-sorted one. This is usually an undesired behavior.

If layer is negative, the layers are accessed from the last one.

void set_layer_y_sort_origin ( int layer, int y_sort_origin )

Sets a layer’s Y-sort origin value. This Y-sort origin value is added to each tile’s Y-sort origin value.

This allows, for example, to fake a different height level on each layer. This can be useful for top-down view games.

If layer is negative, the layers are accessed from the last one.

void set_layer_z_index ( int layer, int z_index )

Sets a layers Z-index value. This Z-index is added to each tile’s Z-index value.

If layer is negative, the layers are accessed from the last one.

void set_navigation_map ( int layer, RID map )

Assigns a NavigationServer2D navigation map RID to the specified TileMap layer.

By default the TileMap uses the default World2D navigation map for the first TileMap layer. For each additional TileMap layer a new navigation map is created for the additional layer.

In order to make NavigationAgent2D switch between TileMap layer navigation maps use NavigationAgent2D.set_navigation_map with the navigation map received from get_navigation_map.

void set_pattern ( int layer, Vector2i position, TileMapPattern pattern )

Paste the given TileMapPattern at the given position and layer in the tile map.
