For Each Target Loop

Activates the ‘Loop Body’ signal once for each target in ‘Targets’, making the current array member available in the output ‘Target’ with its index in ‘Array Index’. After every element of ‘Targets’ has been processed the ‘Finished’ signal is activated. All of this will happen in a single execution of the node, giving you the ability to evaluate a downstream graph multiple times with different inputs coming from the changing ‘Target’ output.

Installation

To use this node enable omni.graph.action_nodes in the Extension Manager.

Inputs

Name	Type	Descripton	Default
Exec In (inputs:execIn)	execution	Signal to the graph that this node is ready to be executed.	None
Targets (inputs:targets)	target	The targets array to loop over	None
	Metadata	allowMultiInputs = 1

Outputs

Name	Type	Descripton	Default
Array Index (outputs:arrayIndex)	int	The value of the current index being visited by the loop. Keeps the value of the last index after the loop has completed. The index starts at zero and increments by one as it walks through the members of ‘Targets’.	None
Finished (outputs:finished)	execution	When the final element of ‘Targets’ has been processed signal the graph that execution can continue downstream.	None
Loop Body (outputs:loopBody)	execution	For each member of ‘Targets’ signal the graph that execution can continue downstream.	None
Target (outputs:target)	target	The current member of ‘Targets’ being visited by the loop. Keeps the value of the last array element after the loop has completed.	None
