/** @brief TMXLayer represents the TMX layer.
|
|
|
|
It is a subclass of SpriteBatchNode. By default the tiles are rendered using a TextureAtlas.
|
|
If you modify a tile on runtime, then, that tile will become a Sprite, otherwise no Sprite objects are created.
|
|
The benefits of using Sprite objects as tiles are:
|
|
- tiles (Sprite) 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 different
|
|
value, like 0.5.
|
|
|
|
For further information, please see the programming guide:
|
|
|
|
http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:tiled_maps
|
|
|
|
@since v0.8.1
|
|
Tiles can have tile flags for additional properties. At the moment only flip horizontal and flip vertical are used. These bit flags are defined in TMXXMLParser.h.
