That's the question xD
Given an instance of a CCSprite in cocos2d in iphone, what method can I use to obtain the image width and height?
The CCSprite class has a bounding box property that's a CGRect:
CCSprite *sprite = [CCSprite spriteWithFile: @"file.png"];
int width = [sprite boundingBox].size.width;
I added a width and height methods to my CCSprite subclass.
-(CGFloat) width
{
return [self boundingBox].size.width;
}
-(CGFloat) height
{
return [self boundingBox].size.height;
}
raw width:sprite.contentSize.width
raw height:sprite.contentSize.height
current width:
sprite.contentSize.width * sprite.scaleX
current height:
sprite.contentSize.height * sprite.scaleY
IN cocos2d-x
sprite->boundingBox().size.width;
sprite->boundingBox().size.height;
In cocos2d-x v3.x, boundingBox
is deprecated in the Node class (i.e. the super class of Sprite). Use the following code instead:
auto spriteWidth = sprite->getTextureRect().size.width;
auto spriteHeight = sprite->getTextureRect().size.height;
or
auto spriteWidth = sprite->getContentSize().width;
auto spriteHeight = sprite->getContentSize().height;
Answer for 2018 (Cocos2d-x v3.x:)
The other answers are incomplete and out-of-date.
Note that I'm using JavaScript below along with destructuring assignment syntax. Be sure to view the Cocos API documentation for your language implementation.
getBoundingBox()
Gives you the:
- Scaled size (the size after
setScale()
is applied to the sprite). - Coordinates of sprite on the screen. Note that the default
anchorPoint
for sprites is (0.5, 0.5), while this coordinate represents the (0, 0) position. In other words, if the anchorPoint is set at the default, thengetBoundingBox().x
+getBoundingBox().width
/ 2 =getPosition().x
(the x value you set insetPosition()
).
Example:
const boundingBox = sprite.getBoundingBox();
const { x, y, width, height } = boundingBox;
getContentSize()
Gives you the:
- Unscaled size.
Example:
const contentSize = sprite.getContentSize();
const { x, y } = contentSize;
getTextureRect()
Gives you the:
- Unscaled size.
- Coordinates of sprite on the texture from which it is extracted (i.e. sprite sheet)
Example:
const textureRect = sprite.getTextureRect();
const { x, y, width, height } = textureRect;
