Exposes a 2D atlas texture as a set of tiles for a TileSet resource.

An atlas is a grid of tiles laid out on a texture. Each tile in the grid must be exposed using create_tile. Those tiles are then indexed using their coordinates in the grid.

Each tile can also have a size in the grid coordinates, making it more or less cells in the atlas.

Alternatives version of a tile can be created using create_alternative_tile, which are then indexed using an alternative ID. The main tile (the one in the grid), is accessed with an alternative ID equal to 0.

Each tile alternate has a set of properties that is defined by the source's TileSet layers. Those properties are stored in a TileData object that can be accessed and modified using get_tile_data.

As TileData properties are stored directly in the TileSetAtlasSource resource, their properties might also be set using TileSetAtlasSource.set("<coords_x>:<coords_y>/<alternative_id>/<tile_data_property>").

 Enum TileAnimationMode<>():Enum

TILE_ANIMATION_MODE_DEFAULT = 0

Tile animations start at same time, looking identical.


TILE_ANIMATION_MODE_RANDOM_START_TIMES = 1

Tile animations start at random times, looking varied.


TILE_ANIMATION_MODE_MAX = 2

Represents the size of the TileAnimationMode enum.

 Vector2i margins<>():Vector2i

Margins, in pixels, to offset the origin of the grid in the texture.

 Vector2i separation<>():Vector2i

Separation, in pixels, between each tile texture region of the grid.

 Texture2D texture<>():Texture2D

The atlas texture.

 Vector2i texture_region_size<>():Vector2i

The base tile size in the texture (in pixel). This size must be bigger than the TileSet's tile_size value.

 bool use_texture_padding<>():bool

If true, generates an internal texture with an additional one pixel padding around each tile. Texture padding avoids a common artifact where lines appear between tiles.

Disabling this setting might lead a small performance improvement, as generating the internal texture requires both memory and processing time when the TileSetAtlasSource resource is modified.

 void clear_tiles_outside_texture<>():void

Removes all tiles that don't fit the available texture area. This method iterates over all the source's tiles, so it's advised to use has_tiles_outside_texture beforehand.

 int create_alternative_tile<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int=, int:=, ):int

Creates an alternative tile for the tile at coordinates atlas_coords. If alternative_id_override is -1, give it an automatically generated unique ID, or assigns it the given ID otherwise.

Returns the new alternative identifier, or -1 if the alternative could not be created with a provided alternative_id_override.

 void create_tile<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, Vector2i=, Vector2i:=, 1 )=, ):1=, ):void

Creates a new tile at coordinates atlas_coords with the given size.

 Vector2i get_atlas_grid_size<>():Vector2i

Returns the atlas grid size, which depends on how many tiles can fit in the texture. It thus depends on the texture's size, the atlas margins, and the tiles' texture_region_size.

 int get_next_alternative_tile_id<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):int

Returns the alternative ID a following call to create_alternative_tile would return.

 Texture2D get_runtime_texture<>():Texture2D

If use_texture_padding is false, returns texture. Otherwise, returns and internal ImageTexture created that includes the padding.

 Rect2i get_runtime_tile_texture_region<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int frame=, frame:int=, ):Rect2i

Returns the region of the tile at coordinates atlas_coords for the given frame inside the texture returned by get_runtime_texture.

Note: If use_texture_padding is false, returns the same as get_tile_texture_region.

 int get_tile_animation_columns<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):int

Returns how many columns the tile at atlas_coords has in its animation layout.

 float get_tile_animation_frame_duration<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int frame_index=, frame_index:int=, ):float

Returns the animation frame duration of frame frame_index for the tile at coordinates atlas_coords.

 int get_tile_animation_frames_count<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):int

Returns how many animation frames has the tile at coordinates atlas_coords.

 TileAnimationMode get_tile_animation_mode<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):TileAnimationMode

Returns the tile animation mode of the tile at atlas_coords. See also set_tile_animation_mode.

 Vector2i get_tile_animation_separation<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):Vector2i

Returns the separation (as in the atlas grid) between each frame of an animated tile at coordinates atlas_coords.

 float get_tile_animation_speed<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):float

Returns the animation speed of the tile at coordinates atlas_coords.

 float get_tile_animation_total_duration<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):float

Returns the sum of the sum of the frame durations of the tile at coordinates atlas_coords. This value needs to be divided by the animation speed to get the actual animation loop duration.

 Vector2i get_tile_at_coords<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):Vector2i

If there is a tile covering the atlas_coords coordinates, returns the top-left coordinates of the tile (thus its coordinate ID). Returns Vector2i(-1, -1) otherwise.

 TileData get_tile_data<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int alternative_tile=, alternative_tile:int=, ):TileData

Returns the TileData object for the given atlas coordinates and alternative ID.

 Vector2i get_tile_size_in_atlas<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):Vector2i

Returns the size of the tile (in the grid coordinates system) at coordinates atlas_coords.

 Rect2i get_tile_texture_region<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int frame=0, frame:int=0, ):Rect2i

Returns a tile's texture region in the atlas texture. For animated tiles, a frame argument might be provided for the different frames of the animation.

 PackedVector2Array get_tiles_to_be_removed_on_change<>( Texture2D texture=, texture:Texture2D=, Vector2i margins=, margins:Vector2i=, Vector2i separation=, separation:Vector2i=, Vector2i texture_region_size=, texture_region_size:Vector2i=, ):PackedVector2Array

Returns an array of tiles coordinates ID that will be automatically removed when modifying one or several of those properties: texture, margins, separation or texture_region_size. This can be used to undo changes that would have caused tiles data loss.

 bool has_room_for_tile<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, Vector2i size=, size:Vector2i=, int animation_columns=, animation_columns:int=, Vector2i animation_separation=, animation_separation:Vector2i=, int frames_count=, frames_count:int=, Vector2i=, Vector2i:=, -=, -:=, ):bool

Returns whether there is enough room in an atlas to create/modify a tile with the given properties. If ignored_tile is provided, act as is the given tile was not present in the atlas. This may be used when you want to modify a tile's properties.

 bool has_tiles_outside_texture<>():bool

Checks if the source has any tiles that don't fit the texture area (either partially or completely).

 void move_tile_in_atlas<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, Vector2i=, Vector2i:=, -=, -:=, Vector2i=, Vector2i:=, -=, -:=, ):void

Move the tile and its alternatives at the atlas_coords coordinates to the new_atlas_coords coordinates with the new_size size. This functions will fail if a tile is already present in the given area.

If new_atlas_coords is Vector2i(-1, -1), keeps the tile's coordinates. If new_size is Vector2i(-1, -1), keeps the tile's size.

To avoid an error, first check if a move is possible using has_room_for_tile.

 void remove_alternative_tile<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int alternative_tile=, alternative_tile:int=, ):void

Remove a tile's alternative with alternative ID alternative_tile.

Calling this function with alternative_tile equals to 0 will fail, as the base tile alternative cannot be removed.

 void remove_tile<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, ):void

Remove a tile and its alternative at coordinates atlas_coords.

 void set_alternative_tile_id<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int alternative_tile=, alternative_tile:int=, int new_id=, new_id:int=, ):void

Change a tile's alternative ID from alternative_tile to new_id.

Calling this function with new_id of 0 will fail, as the base tile alternative cannot be moved.

 void set_tile_animation_columns<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int frame_columns=, frame_columns:int=, ):void

Sets the number of columns in the animation layout of the tile at coordinates atlas_coords. If set to 0, then the different frames of the animation are laid out as a single horizontal line in the atlas.

 void set_tile_animation_frame_duration<>( Vector2i atlas_coords=, atlas_coords:Vector2i=, int frame_index=, frame_index:int=, float duration=, duration:float=, ):void
