Description
|
|
-----------
|
|
|
|
BTEvaluateExpression action evaluates an :ref:`expression_string<class_BTEvaluateExpression_property_expression_string>` on the specified ``Node`` or ``Object`` instance and returns ``SUCCESS`` when the ``Expression`` executes successfully.
|
|
|
|
Returns ``FAILURE`` if the action encounters an issue during the ``Expression`` parsing or execution.
