Segfault with CCLayerColor and normal behavior with CCLayer

cocos2d-x C++
#1

Hi,
I have some troubles with CCLayerColor. I have a class that works well when inheriting from CCLayer, and causing a Segfault when inheriting from CCLayerColor.

class MyLayer : public CCLayer{

bool MyLayer::init(){

    if(!CCLayer::init())
        return false;

    CCMenuItemImage *item = CCMenuItemImage::create(
                                        "fly/menu/YesButton.png",
                                        "fly/menu/YesButtonHover.png"));
    ...
}

The preceding code works well.

class MyLayer : public CCLayerColor{

bool MyLayer::init(){

    if(!CCLayerColor::init())
        return false;

    CCMenuItemImage *item = CCMenuItemImage::create(
                                        "fly/menu/YesButton.png",
                                        "fly/menu/YesButtonHover.png"));
    ...
}

The preceding code causes me this error:

Do you have a clue to solve this issue ?
Thanks

#2

How do you create instance of that class?

#3

With the default constructor indeed…
But with create(), MyLayer::init() does not seems to be called.

CCLayer* l = MyLayer::create();
l->init();

Do I need to implement MyLayer::create() and make it return a MyLayer object ?

#4

Yes. You can use CREATE_FUNC macro for this.
