While Loop

Description

While Loop Node The While Loop Node will run the node flow that is connected to its Body output port repeatedly while the result of evaluating the input at the Condition port is non-zero.

When the loop is complete, the logic graph will continue with the flow connected to the Exit port.


Ports

Flow In
In order for this node to perform its operation, it must be connected into an active flow using this input port. The flow will ultimately originate at a Trigger node but can come from the Flow Out port of any other flow node.
Body
The nodes that are to be repeatedly executed during the loop. Execution will continue while there is a node connected to the Flow Out of the last node executed, the body ends when there is no connection to the Flow Out, at which point the index is updated and the node will check if it is to run the loop again or exit.
Condition
An integer input port providing the value to check at each loop iteration. If the value is 0, the loop exits, if it is non-zero, it loops again.
Exit
A node connected to the Flow Out port will be executed in sequence following the completion of this node's operation.
