cocos2d-x buttons

cocos2d-x C++
#1

Hey,

Does Anyone know how to create a button and check if it got pressed or not?

at the moment i’m using the following code:

auto bt1 = MenuItemImage::create("arrow_left.png","arrow_left.png",CC_CALLBACK_1(InGameScene::menuBT1Callback, this));
    auto bt = Menu::create(bt1, NULL);
    bt->setPosition(350,500);
    
    bt->setPositionZ(10);
    bt->setScale(1);
    this->addChild(bt,1);

But, this only recognizes clicks, but not if it’s still pressed or if it got released.
I want to do something as long as the button is pressed and stop if button is released.

As far as I know subclasses of MenuItem do not support what you need.
But you could subclass the new ui::button and override onPressStateChangedToPressed() and onPressStateChangedToNormal()

You don’t have to make subclass of ui::Button to catch press and release.

auto btn = ui::Button::create();
btn->addTouchEventListener(CC_CALLBACK_2(SomeClass::onButtonTouch, this));

void SomeClass::onButtonTouch(Ref* pSender, ui::Widget::TouchEventType type)
{
    switch (type)
    {
    case ui::Widget::TouchEventType::BEGAN:
        break;
    case ui::Widget::TouchEventType::MOVED:
        break;
    case ui::Widget::TouchEventType::ENDED:
        break;
    case ui::Widget::TouchEventType::CANCELED:
        break;
    default:
        break;
    }
}
