setAll(key, value, checkAlive, checkVisible, operation, force)
Quickly set the same property across all children of this group to a new value. This call doesn't descend down children, so if you have a Group inside of this group, the property will be set on the group but not its children.If you need that ability please see Group.setAllChildren. The operation parameter controls how the new value is assigned to the property, from simple replacement to addition and multiplication.
