/**
|
|
|
|
* Sprite is a 2d image ( http://en.wikipedia.org/wiki/Sprite_(computer_graphics) ).
|
|
|
|
*
|
|
|
|
* Sprite can be created with an image, or with a sub-rectangle of an image.
|
|
|
|
*
|
|
|
|
* To optimize the Sprite rendering, please follow the following best practices:
|
|
|
|
* - Put all your sprites in the same spritesheet (http://www.codeandweb.com/what-is-a-sprite-sheet).
|
|
|
|
* - Use the same blending function for all your sprites.
|
|
|
|
* - ...and the Renderer will automatically "batch" your sprites (will draw all of them in one OpenGL call).
|
|
|
|
*
|
|
|
|
* Sprite has 4 types or rendering modes:
|
|
|
|
*
|
|
|
|
* - `QUAD`: Renders the sprite using 2 triangles (1 rectangle): uses small memory, but renders empty pixels (slow)
|
2021-12-25 10:04:45 +08:00
|
|
|
* - `POLYGON`: Renders the sprite using many triangles (depending on the setting): Uses more memory, but doesn't
|
|
|
|
* render so much empty pixels (faster)
|
|
|
|
* - `SLICE9`: Renders the sprite using 18 triangles (9 rectangles). Useful to to scale buttons an other rectangular
|
|
|
|
* sprites
|
|
|
|
* - `QUAD_BATCHNODE`: Renders the sprite using 2 triangles (1 rectangle) with a static batch, which has some
|
|
|
|
* limitations (see below)
|
2019-11-23 20:27:39 +08:00
|
|
|
*
|
2021-12-25 10:04:45 +08:00
|
|
|
* By default, the sprite uses `QUAD` mode. But can be changed to `POLYGON` when calling `setPolygonInfo()`. To use
|
|
|
|
* `SLICE9` call `setCenterRect()` or `serCenterRectNormalized()`. To use `QUAD_BATCHNODE` parent the sprite to a
|
|
|
|
* `SpriteBatchNode` object.
|
2019-11-23 20:27:39 +08:00
|
|
|
*
|
|
|
|
*
|
|
|
|
* `QUAD_BATCHNODE` is deprecated and should be avoid. It has the following limitations:
|
|
|
|
*
|
|
|
|
* - The Alias/Antialias property belongs to `SpriteBatchNode`, so you can't individually set the aliased property.
|
2021-12-25 10:04:45 +08:00
|
|
|
* - The Blending function property belongs to `SpriteBatchNode`, so you can't individually set the blending function
|
|
|
|
* property.
|
2019-11-23 20:27:39 +08:00
|
|
|
* - `ParallaxNode` is not supported, but can be simulated with a "proxy" sprite.
|
|
|
|
* - Sprites can only have other Sprites (or subclasses of Sprite) as children.
|
|
|
|
*
|
|
|
|
* The default anchorPoint in Sprite is (0.5, 0.5).
