interface ITileContainer
package openfl.display
implemented by TileContainer, Tilemap
Available on all platforms
ITileContainer is an interface implemented by compatible tile container objects, including the Tilemap and TileContainer classes.
Variables
Methods
Adds a Tile instance to this ITileContainer instance. The tile is
added to the front (top) of all other tiles in this ITileContainer
instance. (To add a tile to a specific index position, use the addTileAt()
method.)
Parameters:
tile | The Tile instance to add to this ITileContainer instance. |
|---|
Returns:
The Tile instance that you pass in the tile parameter.
addTileAt (tile:Tile, index:Int):Tile
Adds a Tile instance to this ITileContainer instance. The tile is added at the index position specified. An index of 0 represents the back (bottom) of the rendered list for this ITileContainer object.
For example, the following example shows three tiles, labeled a, b, and c, at index positions 0, 2, and 1, respectively:
Parameters:
tile | The Tile instance to add to this ITileContainer instance. |
|---|---|
index | The index position to which the tile is added. If you specify a currently occupied index position, the tile object that exists at that position and all higher positions are moved up one position in the tile list. |
Returns:
The Tile instance that you pass in the tile parameter.
addTiles (tiles:Array<Tile>):Array<Tile>
Adds an Array of Tile instances to this ITileContainer instance. The tiles are added to the front (top) of all other tiles in this ITileContainer instance.
Parameters:
tiles | The Tile instances to add to this ITileContainer instance. |
|---|
Returns:
The Tile Array that you pass in the tiles parameter.
Determines whether the specified tile is contained within the
ITileContainer instance. The search includes the entire tile list including
this ITileContainer instance. Grandchildren, great-grandchildren, and so on
each return true.
Parameters:
tile | The tile object to test. |
|---|
Returns:
true if the tile object is contained within the ITileContainer;
otherwise false.
Returns the tile instance that exists at the specified index.
Parameters:
index | The index position of the tile object. |
|---|
Returns:
The tile object at the specified index position.
getTileIndex (tile:Tile):Int
Returns the index position of a contained Tile instance.
Parameters:
child | The Tile instance to identify. |
|---|
Returns:
The index position of the tile object to identify.
removeTile (tile:Tile):Tile
Removes the specified Tile instance from the tile list of the ITileContainer instance. The index positions of any tile objects above the tile in the ITileContainer are decreased by 1.
Parameters:
tile | The Tile instance to remove. |
|---|
Returns:
The Tile instance that you pass in the tile parameter.
removeTileAt (index:Int):Tile
Removes a Tile from the specified index position in the tile list of the
ITileContainer. The index positions of any tile objects above the tile in
the ITileContainer are decreased by 1.
Parameters:
index | The index of the Tile to remove. |
|---|
Returns:
The Tile instance that was removed.
removeTiles (beginIndex:Int = 0, endIndex:Int = 0x7fffffff):Void
Removes all Tile instances from the tile list of the ITileContainer instance.
Parameters:
beginIndex | The beginning position. |
|---|---|
endIndex | The ending position. |
setTileIndex (tile:Tile, index:Int):Void
Changes the position of an existing tile in the tile container. This affects the layering of tile objects. For example, the following example shows three tile objects, labeled a, b, and c, at index positions 0, 1, and 2, respectively:
When you use the setTileIndex() method and specify an
index position that is already occupied, the only positions that change
are those in between the tile object's former and new position. All
others will stay the same. If a tile is moved to an index LOWER than its
current index, all tiles in between will INCREASE by 1 for their index
reference. If a tile is moved to an index HIGHER than its current index,
all tiles in between will DECREASE by 1 for their index reference. For
example, if the tile container in the previous example is named
container, you can swap the position of the tile objects
labeled a and b by calling the following code:
container.setTileIndex(container.getTileAt(1), 0);This code results in the following arrangement of objects:
Parameters:
tile | The Tile instance for which you want to change the index number. |
|---|---|
index | The resulting index number for the |
swapTiles (tile1:Tile, tile2:Tile):Void
Swaps the z-order (front-to-back order) of the two specified tile objects. All other tile objects in the tile container remain in the same index positions.
Parameters:
child1 | The first tile object. |
|---|---|
child2 | The second tile object. |
swapTilesAt (index1:Int, index2:Int):Void
Swaps the z-order (front-to-back order) of the tile objects at the two specified index positions in the tile list. All other tile objects in the tile container remain in the same index positions.
Parameters:
index1 | The index position of the first tile object. |
|---|---|
index2 | The index position of the second tile object. |
