+ However, the downside is that when the audio data is freed you must

+ and 3.1.2 has shown that this may occur if a buffer is being used by a source with state = AL_PLAYING
+ when the buffer is deleted. If the data is freed too quickly after the source is stopped then
+ a crash will occur. The implemented workaround is that when static buffers are used the unloadBuffer code will wait for
+ any playing sources to finish playing before the associated buffer and data are deleted, however, this delay may negate any
+ performance gains that are achieved during loading.
+
+ Performance tests on a 1st gen iPod running OS 2.2.1 loading the CocosDenshionDemo sounds were ~0.14 seconds without

+/**
+@file
+@b IMPORTANT
+There are 3 different ways of using CocosDenshion. Depending on which you choose you
+will need to include different files and frameworks.
+
+@par SimpleAudioEngine
+This is recommended for basic audio requirements. If you just want to play some sound fx
+and some background music and have no interest in learning the lower level workings then
+this is the interface to use.
+
+Requirements:
+ - Firmware: OS 2.2 or greater
+ - Files: SimpleAudioEngine.*, CocosDenshion.*
+ - Frameworks: OpenAL, AudioToolbox, AVFoundation
+
+@par CDAudioManager
+CDAudioManager is basically a thin wrapper around an AVAudioPlayer object used for playing
+background music and a CDSoundEngine object used for playing sound effects. It manages the
+audio session for you deals with audio session interruption. It is fairly low level and it
+is expected you have some understanding of the underlying technologies. For example, for
+many use cases regarding background music it is expected you will work directly with the
+backgroundMusic AVAudioPlayer which is exposed as a property.
+
+Requirements:
+ - Firmware: OS 2.2 or greater
+ - Files: CDAudioManager.*, CocosDenshion.*
+ - Frameworks: OpenAL, AudioToolbox, AVFoundation
+
+@par CDSoundEngine
+CDSoundEngine is a sound engine built upon OpenAL and derived from Apple's oalTouch
+example. It can playback up to 32 sounds simultaneously with control over pitch, pan
+and gain. It can be set up to handle audio session interruption automatically. You
+may decide to use CDSoundEngine directly instead of CDAudioManager or SimpleAudioEngine
+because you require OS 2.0 compatibility.
+
+Requirements:
+ - Firmware: OS 2.0 or greater
+ - Files: CocosDenshion.*
+ - Frameworks: OpenAL, AudioToolbox

+It has an start time, and a finish time. The finish time is the parameter
+duration plus the start time.
+
+These CCActionInterval actions have some interesting properties, like:
+ - They can run normally (default)
+ - They can run reversed with the reverse method
+ - They can run with the time altered with the Accelerate, AccelDeccel and Speed actions.
+
+For example, you can simulate a Ping Pong effect running the action normally and
+then running it again in Reverse mode.
+
+Example:
+

+
+ - It doesn't work on batched nodes like CCSprite objects when they are parented to a CCSpriteBatchNode object.
+
+ - It is recommended to use it ONLY if you are going to create 3D effects. For 2D effecs, use the action CCFollow or position/scale/rotate.

+ - It can be used as part of a menu item.
+ - anchorPoint can be used to align the "label"

+
+ CCLabelBMFont implements the protocol CCLabelProtocol, like CCLabel and CCLabelAtlas.

+/** CCNode is the main element. Anything thats gets drawn or contains things that get drawn is a CCNode.
+ The most popular CCNodes are: CCScene, CCLayer, CCSprite, CCMenu.
+
+ The main features of a CCNode are:
+ - They can contain other CCNode nodes (addChild, getChildByTag, removeChild, etc)
+ - They can schedule periodic callback (schedule, unschedule, etc)
+ - They can execute actions (runAction, stopAction, etc)
+
+ Some CCNode nodes provide extra functionality for them or their children.
+
+ Subclassing a CCNode usually means (one/all) of:
+ - overriding init to initialize resources and schedule callbacks
+ - create callbacks to handle the advancement of time
+ - overriding draw to render the node
+
+ Features of CCNode:
+ - position
+ - scale (x, y)
+ - rotation (in degrees, clockwise)
+ - CCCamera (an interface to gluLookAt )
+ - CCGridBase (to do mesh transformations)
+ - anchor point
+ - size
+ - visible
+ - z-order
+ - openGL z position
+
+ Default values:
+ - rotation: 0
+ - position: (x=0,y=0)
+ - scale: (x=1,y=1)
+ - contentSize: (x=0,y=0)
+ - anchorPoint: (x=0,y=0)
+
+ Limitations:
+ - A CCNode is a "void" object. It doesn't have a texture
+
+ Order in transformations with grid disabled
+ -# The node will be translated (position)
+ -# The node will be rotated (rotation)
+ -# The node will be scaled (scale)
+ -# The node will be moved according to the camera values (camera)
+
+ Order in transformations with grid enabled
+ -# The node will be translated (position)
+ -# The node will be rotated (rotation)
+ -# The node will be scaled (scale)
+ -# The grid will capture the screen
+ -# The node will be moved according to the camera values (camera)
+ -# The grid will render the captured screen
+
+ Camera:
+ - Each node has a camera. By default it points to the center of the CCNode.

+
+ cocos2d also supports particles generated by Particle Designer (http://particledesigner.71squared.com/).
+ 'Radius Mode' in Particle Designer uses a fixed emit rate of 30 hz. Since that can't be guarateed in cocos2d,
+ cocos2d uses a another approach, but the results are almost identical.
+
+ cocos2d supports all the variables used by Particle Designer plus a bit more:
+ - spinning particles (supported when using CCParticleSystemQuad)
+ - tangential acceleration (Gravity mode)
+ - radial acceleration (Gravity mode)
+ - radius direction (Radius mode) (Particle Designer supports outwards to inwards direction only)
+
+ It is possible to customize any of the above mentioned properties in runtime. Example:
+
+ @code
+ emitter.radialAccel = 15;
+ emitter.startSpin = 0;
+ @endcode

+ * CCSprite can be created with an image, or with a sub-rectangle of an image.
+ *
+ * If the parent or any of its ancestors is a CCSpriteBatchNode then the following features/limitations are valid
+ * - Features when the parent is a CCBatchNode:
+ * - MUCH faster rendering, specially if the CCSpriteBatchNode has many children. All the children will be drawn in a single batch.
+ *
+ * - Limitations
+ * - Camera is not supported yet (eg: CCOrbitCamera action doesn't work)
+ * - GridBase actions are not supported (eg: CCLens, CCRipple, CCTwirl)
+ * - The Alias/Antialias property belongs to CCSpriteBatchNode, so you can't individually set the aliased property.
+ * - The Blending function property belongs to CCSpriteBatchNode, so you can't individually set the blending function property.
+ * - Parallax scroller is not supported, but can be simulated with a "proxy" sprite.
+ *
+ * If the parent is an standard CCNode, then CCSprite behaves like any other CCNode:
+ * - It supports blending functions
+ * - It supports aliasing / antialiasing
+ * - But the rendering will be slower: 1 draw per children.
+ *
+ * The default anchorPoint in CCSprite is (0.5, 0.5).

+/** CCTMXLayer represents the TMX layer.
+
+ It is a subclass of CCSpriteSheet. By default the tiles are rendered using a CCTextureAtlas.
+ If you mofify a tile on runtime, then, that tile will become a CCSprite, otherwise no CCSprite objects are created.
+ The benefits of using CCSprite objects as tiles are:
+ - tiles (CCSprite) can be rotated/scaled/moved with a nice API
+
+ If the layer contains a property named "cc_vertexz" with an integer (in can be positive or negative),
+ then all the tiles belonging to the layer will use that value as their OpenGL vertex Z for depth.
+
+ On the other hand, if the "cc_vertexz" property has the "automatic" value, then the tiles will use an automatic vertex Z value.
+ Also before drawing the tiles, GL_ALPHA_TEST will be enabled, and disabled after drawing them. The used alpha func will be:
+
+ glAlphaFunc( GL_GREATER, value )
+
+ "value" by default is 0, but you can change it from Tiled by adding the "cc_alpha_func" property to the layer.
+ The value 0 should work for most cases, but if you have tiles that are semi-transparent, then you might want to use a differnt
+ value, like 0.5.
+
+ For further information, please see the programming guide:
+
+ http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:tiled_maps

+
+ It adds support for the TMX tiled map format used by http://www.mapeditor.org
+ It supports isometric, hexagonal and orthogonal tiles.
+ It also supports object groups, objects, and properties.
+
+ Features:
+ - Each tile will be treated as an CCSprite
+ - The sprites are created on demand. They will be created only when you call "[layer tileAt:]"
+ - Each tile can be rotated / moved / scaled / tinted / "opacitied", since each tile is a CCSprite
+ - Tiles can be added/removed in runtime
+ - The z-order of the tiles can be modified in runtime
+ - Each tile has an anchorPoint of (0,0)
+ - The anchorPoint of the TMXTileMap is (0,0)
+ - The TMX layers will be added as a child
+ - The TMX layers will be aliased by default
+ - The tileset image will be loaded using the CCTextureCache
+ - Each tile will have a unique tag
+ - Each tile will have a unique z value. top-left: z=1, bottom-right: z=max z
+ - Each object group will be treated as an NSMutableArray
+ - Object class which will contain all the properties in a dictionary
+ - Properties can be assigned to the Map, Layer, Object Group, and Object
+
+ Limitations:
+ - It only supports one tileset per layer.
+ - Embeded images are not supported
+ - It only supports the XML format (the JSON format is not supported)
+
+ Technical description:
+ Each layer is created using an CCTMXLayer (subclass of CCSpriteSheet). If you have 5 layers, then 5 CCTMXLayer will be created,
+ unless the layer visibility is off. In that case, the layer won't be created at all.
+ You can obtain the layers (CCTMXLayer objects) at runtime by:
+ - [map getChildByTag: tag_number]; // 0=1st layer, 1=2nd layer, 2=3rd layer, etc...
+ - [map layerNamed: name_of_the_layer];
+
+ Each object group is created using a CCTMXObjectGroup which is a subclass of NSMutableArray.
+ You can obtain the object groups at runtime by:
+ - [map objectGroupNamed: name_of_the_object_group];
+
+ Each object is a CCTMXObject.
+
+ Each property is stored as a key-value pair in an NSMutableDictionary.
+ You can obtain the properties at runtime by:
+
+ [map propertyNamed: name_of_the_property];
+ [layer propertyNamed: name_of_the_property];
+ [objectGroup propertyNamed: name_of_the_property];
+ [object propertyNamed: name_of_the_property];

+ Firstly, the dispatcher sends the received touches to the targeted touches.

+ to the Standard Touch Handlers.

+ Based on Chipmunk cpArray.
+ ccArray is a faster alternative to NSMutableArray, it does pretty much the
+ same thing (stores NSObjects and retains/releases them appropriately). It's
+ faster because:
+ - it uses a plain C interface so it doesn't incur Objective-c messaging overhead
+ - it assumes you know what you're doing, so it doesn't spend time on safety checks
+ (index out of bounds, required capacity etc.)
+ - comparisons are done using pointer equality instead of isEqual
+
+ There are 2 kind of functions:
+ - ccArray functions that manipulates objective-c objects (retain and release are performanced)
+ - ccCArray functions that manipulates values like if they were standard C structures (no retain/release is performed)

+/* Bucket expansion has the effect of doubling the number of buckets

+ * items will distribute more or less evenly into the new buckets
+ * (the extent to which this is true is a measure of the quality of
+ * the hash function as it applies to the key domain).
+ *
+ * With the items distributed into more buckets, the chain length
+ * (item count) in each bucket is reduced. Thus by expanding buckets
+ * the hash keeps a bound on the chain length. This bounded chain
+ * length is the essence of how a hash provides constant time lookup.
+ *
+ * The calculation of tbl->ideal_chain_maxlen below deserves some
+ * explanation. First, keep in mind that we're calculating the ideal
+ * maximum chain length based on the *new* (doubled) bucket count.
+ * In fractions this is just n/b (n=number of items,b=new num buckets).
+ * Since the ideal chain length is an integer, we want to calculate
+ * ceil(n/b). We don't depend on floating point arithmetic in this
+ * hash, so to calculate ceil(n/b) with integers we could write
+ *
+ * ceil(n/b) = (n/b) + ((n%b)?1:0)
+ *
+ * and in fact a previous version of this hash did just that.
+ * But now we have improved things a bit by recognizing that b is
+ * always a power of two. We keep its base 2 log handy (call it lb),
+ * so now we can write this with a bit shift and logical AND:
+ *
+ * ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0)
