Detailed Description
The FallbackNode is used to try different strategies, until one succeeds. If any child returns RUNNING, previous children will NOT be ticked again.
- If all the children return FAILURE, this node returns FAILURE.
- If a child returns RUNNING, this node returns RUNNING.
- If a child returns SUCCESS, stop the loop and return SUCCESS.
