Swallowing Events

When you have a listener and you want an object to accept the event it was given you must swallow it. To say it another way, you consume it so that it doesn't get passed to other objects in highest to lowest priority. This is easy to do.

// When "swallow touches" is true, then returning 'true' from the
// onTouchBegan method will "swallow" the touch event, preventing
// other listeners from using it.
listener1->setSwallowTouches(true);

// you should also return true in onTouchBegan()

listener1->onTouchBegan = [](Touch* touch, Event* event){
    // your code

    return true;
};
