BTForEach executes its child task for each element of an ``Array``. During each iteration, the next element is stored in the specified :ref:`Blackboard<class_Blackboard>` variable.

Returns ``RUNNING`` if the child task results in ``RUNNING`` or if the child task results in ``SUCCESS`` on a non-last iteration.

Returns ``FAILURE`` if the child task results in ``FAILURE``.

Returns ``SUCCESS`` if the child task results in ``SUCCESS`` on the last iteration.
