CCScale9Sprite

Hi,
do anyone have an example how to use CCScale9Sprite with setCapInsets? Every time i call the setCapInset function the sprite gets invisible.

THX

The origion for CCScle9Sprite is upper left not lower left.

Beside there is a bug in the following function:

TCCScale9Sprite* TCCScale9Sprite::create(CCRect capInsets, const char* file)
{
TCCScale9Sprite* pReturn = new TCCScale9Sprite();
if ( pReturn && pReturn~~>initWithFile )
{
pReturn~~>autorelease();
return pReturn;
}
CC_SAFE_DELETE(pReturn);
return NULL;
}

It have to be if ( pReturn && pReturn->initWithFile(capInsets, file) )

Did you ever find a solution to this problem? I’m trying to ninepatch scale an image and getting the same result

#3

No … i made a copy of the file and modified the source where it needed to be.

Hi,

I have the same issue: the sprite is not rendered as soon as I set the cap insets (calling setInsetLeft/Top… or setCapInsets)…

@ CCScale9Sprite*s = CCScale9Sprite::createWithSpriteFrameName(“messagebox”);
s~~>setPreferredSize);
s~~>setInsetLeft(15.f);
s~~>setInsetRight;
s~~>setInsetTop(25.0f);
s~~>setInsetBottom;
s~~>setAnchorPoint(ccp(.5f, .5f));
addChild(s);@

Is this the right way to create a CCScale9Sprite?
I couldn’t find any examples in the tests/samples which use setInsetLeft/right/top etc…

Any help?

You need to setContentSize. In my understanding the CCScale9Sprite scales around the content, if there is none it just doesn’t show anything.

#6

I’ve tested with setContentSize & setPreferredSize but still the same issue…

#7

Daniel Brain is right … you need to set the content size. you have to add the caps to the content size. that means if you want to have a inner size of 100 pixel you have to set content site width to 100 + left margin + right margin.

Hi den ranx, did you came with a solution of this?

Or can anyone modify his code to see an example of a working CCScale9Sprite from CCSpriteBatchNode?

Thanks

Hi,

Sorry for the late feedback but here’s how I simply managed to create and resize a CCScale9Sprite.

I create a symmetric image (see screenshot) and load it using the following code. The sprite is automatically split into a 3×3 grid of equal blocks and we can use setContentSize to resize the sprite (only the center block of the sprite will be scaled)

    CCScale9Sprite*sp = CCScale9Sprite::createWithSpriteFrameName("spriteFrameName");
    sp->setContentSize( CCSizeMake(200, 150) );
#10

So am I the only one who can’t create a CCScale9Sprite? I don’t know what else to do.

Here’s my code:

CCScale9Sprite* buttonBG = CCScale9Sprite::createWithSpriteFrameName("menuButtonTop.png");
buttonBG->setContentSize(CCSizeMake(winSize.width-20, 67));
menuElementsBatchNode->addChild(buttonBG);

That way there will be an assertion failure when adding the child to the BatchNode.

CCScale9Sprite* buttonBG = CCScale9Sprite::createWithSpriteFrameName("menuButtonTop.png", CCRectMake(5,5,8,8));
buttonBG->setContentSize(CCSizeMake(winSize.width-20, 67));
menuElementsBatchNode->addChild(buttonBG);

That way there will be an assertion failure when splitting the CCScale9Sprite because the coordinates are calculated the wrong way.

Any tip?

Hi Danadn,

I use CCScale9Sprite::createWithSpriteFrameName because my texture is already loaded and available in the sprite frame cache (CCSpriteFrameCache).

To load a sprite from file use CCScale9Sprite::create(“spriteFileName.png”).

Hope it helps.

Hi den ranx,

I know that, in fact this is my whole code:

    CCSpriteBatchNode* menuElementsBatchNode = CCSpriteBatchNode::create(pvrPath.append("/MenuScene/menuElements.pvr.ccz").c_str());
    this->addChild(menuElementsBatchNode, 0);
    CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile(plistPath.append("/MenuScene/menuElements.plist").c_str());

    CCScale9Sprite* buttonBG = CCScale9Sprite::createWithSpriteFrameName("menuButtonTop.png");
    buttonBG->setContentSize(CCSizeMake(winSize.width-20, 67));
    menuElementsBatchNode->addChild(buttonBG);

Am I doing something wrong? Since I don’t have any sample I can’t compare and also this works for normal CCSprite’s

#13 
CCScale9Sprite* buttonBG = CCScale9Sprite::createWithSpriteFrameName("menuButtonTop.png");
buttonBG->setContentSize(CCSizeMake(winSize.width-20, 67));
menuElementsBatchNode->addChild(buttonBG);

What is the assertion failure message?

Maybe the assertion failed because you’re trying to add CCScale9Sprite which is not a subclass of CCSprite to a CCSpriteBatchNode.

#14

EDIT:

@den: I’ve just seen your answer, so it was that I can’t add CCScale9Sprites to CCSpriteBatchNode. I don’t know if that’s a good practice since for CCSprites the correct way is too add them to the batchNode.

However CCScale9Sprite has a bug with custom insets, it calculates them wrong. I’m trying to fix it.

Thanks

#15

Ok now the images are splitted in the correct way, constructions like the one below will now work:

CCScale9Sprite* buttonBG = CCScale9Sprite::createWithSpriteFrameName("menuButtonTop.png", CCRectMake(5,5,8,8));

here’s the part of the code that is wrong.

*Edit -> Removed: it still fails for other frames on the same sprite sheet

#16

Thanks for the feedback danadn!

Hope the bug will be fixed in the next release.
