You should implement the node follow these steps:

Then once you running ActionTween on the node, the method updateTweenAction will be invoked.

ActionTween is an action that lets you update any property of an object.
For example, if you want to modify the "width" property of a target from 200 to 300 in 2 seconds, then:
@code
auto modifyWidth = ActionTween::create(2, "width", 200, 300);
target->runAction(modifyWidth);

Another example: ScaleTo action could be rewritten using PropertyAction:
@code
// scaleA and scaleB are equivalents
auto scaleA = ScaleTo::create(2, 3); // (duration, to)
auto scaleB = ActionTween::create(2, "scale", 1, 3); // (duration, key, from, to)
