Methods
getLayerName
Gets the layer name.SetLayerName
Set the layer name.getProperty
Return the value for the specific property name.getPositionAt
Returns the position in pixels of a given tile coordinate.removeTileAt
Removes a tile at given tile coordinate.setTileGID
Sets the tile gid (gid = tile global id) at a given tile coordinate.
The Tile GID can be obtained by using the method "tileGIDAt" or by using the TMX editor . Tileset Mgr +1.
If a tile is already placed at that position, then it will be removed.getTileGIDAt
Returns the tile gid at a given tile coordinate.
if it returns 0, it means that the tile is empty.
This method requires the the tile map has not been previously released (eg. don't call layer.releaseMap())getTileAt
Returns the tile (_ccsg.Sprite) at a given a tile coordinate.
The returned _ccsg.Sprite will be already added to the _ccsg.TMXLayer. Don't add it again.
The _ccsg.Sprite can be treated like any other _ccsg.Sprite: rotated, scaled, translated, opacity, color, etc.
You can remove either by calling:- layer.removeChild(sprite, cleanup);
- or layer.removeTileAt(ccp(x,y));
- layer.removeChild(sprite, cleanup);
releaseMap
Dealloc the map that contains the tile position from memory.
Unless you want to know at runtime the tiles positions, you can safely call this method.
If you are going to call layer.getTileGIDAt() then, don't release the map.setContentSize
Sets the untransformed size of the _ccsg.TMXLayer.getTexture
Return texture of cc.SpriteBatchNode.setTexture
Set the texture of cc.SpriteBatchNode.setTileOpacity
Set the opacity of all tilesgetLayerSize
Gets layer size.setLayerSize
Set layer size.getMapTileSize
Size of the map's tile (could be different from the tile's size).setMapTileSize
Set the map tile size.getTiles
Pointer to the map of tiles.setTiles
Pointer to the map of tiles.getTileSet
Tile set information for the layer.setTileSet
Tile set information for the layer.getLayerOrientation
Layer orientation, which is the same as the map orientation.setLayerOrientation
Layer orientation, which is the same as the map orientation.getProperties
properties from the layer. They can be added using Tiled.setProperties
properties from the layer. They can be added using Tiled._createSgNode
Create and returns your new scene graph node (SGNode) to add to scene graph. You should call the setContentSize of the SGNode if its size should be the same with the node's._initSgNode
_removeSgNode
update
Update is called every frame, if the Component is enabled.lateUpdate
LateUpdate is called every frame, if the Component is enabled.__preload
__preload
is called before every onLoad. It is used to initialize the builtin components internally, to avoid checking whether onLoad is called before every public method calls. This method should be removed if script priority is supported.onLoad
When attaching to an active node or its node first activated. onLoad is always called before any start functions, this allows you to order initialization of scripts.start
Called before all scripts' update if the Component is enabled the first time. Usually used to initialize some logic which need to be called after all components'onload
methods called.onEnable
Called when this component becomes enabled and its node is active.onDisable
Called when this component becomes disabled or its node becomes inactive.onDestroy
Called when this component will be destroyed.onFocusInEditor
onLostFocusInEditor
resetInEditor
Called to initialize the component or node’s properties when adding the component the first time or when the Reset command is used. This function is only called in editor.addComponent
Adds a component class to the node. You can also add component to node by passing in the name of the script.getComponent
Returns the component of supplied type if the node has one attached, null if it doesn't.
You can also get component in the node by passing in the name of the script.getComponents
Returns all components of supplied Type in the node.getComponentInChildren
Returns the component of supplied type in any of its children using depth first search.getComponentsInChildren
Returns the components of supplied type in self or any of its children using depth first search._getLocalBounds
If the component's bounding box is different from the node's, you can implement this method to supply a custom axis aligned bounding box (AABB), so the editor's scene view can perform hit test properly.onRestore
onRestore is called after the user clicks the Reset item in the Inspector's context menu or performs an undo operation on this component.
If the component contains the "internal state", short for "temporary member variables which not included
in its CCClass properties", then you may need to implement this function.
The editor will call the getset accessors of your component to record/restore the component's state
for undo/redo operation. However, in extreme cases, it may not works well. Then you should implement
this function to manually synchronize your component's "internal states" with its public properties.
Once you implement this function, all the getset accessors of your component will not be called when
the user performs an undo/redo operation. Which means that only the properties with default value
will be recorded or restored by editor.
Similarly, the editor may failed to reset your component correctly in extreme cases. Then if you need
to support the reset menu, you should manually synchronize your component's "internal states" with its
properties in this function. Once you implement this function, all the getset accessors of your component
will not be called during reset operation. Which means that only the properties with default value
will be reset by editor.
This function is only called in editor mode.
schedule
Schedules a custom selector.
If the selector is already scheduled, then the interval parameter will be updated without scheduling it again.scheduleOnce
Schedules a callback function that runs only once, with a delay of 0 or larger.unschedule
Unschedules a custom callback function.unscheduleAllCallbacks
unschedule all scheduled callback functions: custom callback functions, and the 'update' callback function.
Actions are not affected by this method.destroy
Destroy this Object, and release all its own references to other objects.
Actual object destruction will delayed until before rendering.
After destroy, this CCObject is not usable any more. You can use cc.isValid(obj) to check whether the object is destroyed before accessing it._destruct
Clear all references in the instance.
NOTE: this method will not clear the getter or setter functions which defined in the instance of CCObject. You can override the _destruct method if you need, for example: _destruct: function () { for (var key in this) { if (this.hasOwnProperty(key)) { switch (typeof this[key]) { case 'string': this[key] = ''; break; case 'object': case 'function': this[key] = null; break; } } }
_onPreDestroy
Called before the object being destroyed._serialize
The customized serialization for this object. (Editor Only)_deserialize
Init this object from the custom serialized data.
