I have a vector of MenuItem here:
cocos2d::Vector<cocos2d::MenuItem*> menuItems;
This vector contains 4 MenuItemImages :
menuItems.pushBack(myImage1);
menuItems.pushBack(myImage2);
menuItems.pushBack(myImage3);
menuItems.pushBack(myImage4);
Now I’m trying to set selected and set active these image items through a KeyBoard Listener :
auto keyBoardListener = EventListenerKeyboard::create();
keyBoardListener->onKeyPressed = [&](cocos2d::EventKeyboard::KeyCode keycode, Event* event)
{
switch (keycode)
{
case cocos2d::EventKeyboard::KeyCode::KEY_LEFT_ARROW:
// This should set myImage1 selected but it doesn't work
menuItems[0]->selected();
// This should activates myImage2 but it doesn't work
menuItems[1]->active();
break;
}
};
_eventDispatcher->addEventListenerWithSceneGraphPriority(keyBoardListener, this);
Visual Studio told me that There’s no operator “[]” matches these operands" .
Therefore, I dig into the CCVector.h and found that the operater [] function has been commented out with this comment:
// Don't uses operator since we could not decide whether it needs 'retain'/'release'.
So my question is, how could I access a member of the vector above? Your help is very much appriciated :D.
