Decorator
Decorator tasks are parent tasks that can have a single child. They are designed to either modify the return status of their child (such as the Return Success task) or change the flow of the tree (such as the Repeater task). Decorator tasks will return a status of running when their child is running and success or failure based on the return status of their child.
Decorator tasks cannot be stacked similar to Composite tasks. Each task represents its own functionality. If the Composite task has a green border then it is an Entity-based task and a black border represents a GameObject task.
