/** @brief CCLabelBMFont is a subclass of CCSpriteBatchNode.
|
|
|
|
Features:
|
|
- Treats each character like a CCSprite. This means that each individual character can be:
|
|
- rotated
|
|
- scaled
|
|
- translated
|
|
- tinted
|
|
- change the opacity
|
|
- It can be used as part of a menu item.
|
|
- anchorPoint can be used to align the "label"
|
|
- Supports AngelCode text format
|
|
|
|
Limitations:
|
|
- All inner characters are using an anchorPoint of (0.5f, 0.5f) and it is not recommend to change it
|
|
because it might affect the rendering
|
|
|
|
CCLabelBMFont implements the protocol CCLabelProtocol, like CCLabel and CCLabelAtlas.
|
|
CCLabelBMFont has the flexibility of CCLabel, the speed of CCLabelAtlas and all the features of CCSprite.
|
|
If in doubt, use CCLabelBMFont instead of CCLabelAtlas / CCLabel.
