Detailed Description
The FallbackStarNode is used to try different strategies, until one succeed. 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. Loop is NOT restarted, the same running child will be ticked again.
- If a child returns SUCCESS, stop the loop and returns SUCCESS.
