Detailed Description

IfThenElseNode must have exactly 2 or 3 children. This node is NOT reactive.

The first child is the "statement" of the if.

If that return SUCCESS, then the second child is executed.

Instead, if it returned FAILURE, the third child is executed.

If you have only 2 children, this node will return FAILURE whenever the statement returns FAILURE.

This is equivalent to add AlwaysFailure as 3rd child.

The method used to interrupt the execution of a RUNNING node. Only Async nodes that may return RUNNING should implement it.

Reimplemented from BT::ControlNode.
