I'd like to use "CGRectIntersectsRect" for collision detect like following.
```
if (CGRectIntersectsRect(charRect, enemyRect)) {
    NSLog(@"***COLLISION***");
}
```
When I define CCSprite, I define like following.

CCSprite* charSprite = [CCSprite spriteWithTexture:charSheet.texture rect:CGRectMake(0, 0, 64, 96)];

So, it includes "CGRectMake(0, 0, 64, 96)]"
I guess that CCSprite have information of "rect".

But, I couldn't fine how to get information of "rect" from CCSprite instance.
I tried methods I hope, but they doesn't exist
charSprite.rect
charSprite.getRect
charSprite.rect_
charSprite.contentRect
...

Writing them of below are troublesome.
```
charRect = CGRectMake(
    charSprite.position.x - (charSprite.contentSize.width/2),
    charSprite.position.y - (charSprite.contentSize.height/2),
    charSprite.contentSize.width,
    charSprite.contentSize.height
);
```
```
enemyRect = CGRectMake(
    enemySprite.position.x - (enemySprite.contentSize.width/2),
    enemySprite.position.y - (enemySprite.contentSize.height/2),
    enemySprite.contentSize.width,
    enemySprite.contentSize.height
);
```

CCSprites already come with a CGRect with them:

sprite.boundingBox

so your code would be

if (CGRectIntersectsRect(charSprite.boundingBox, enemySprite.boundingBox)) {
    NSLog(@"***COLLISION***");
}
