Here’s the screenshots to illustrate the example described on the Delay Set Data reference page.
“For example, if you want to swap values of A and B, just using two Get Data nodes and two Set Data nodes (A=B and B=A) would result in both attributes having the same value.”
“However, if you connect the Set Data nodes in the Delay Set Data node, the Set Data operations will be executed at the same time, thus setting the values before any of the Set Data nodes are executed. ”
Oh, that’s what it’s doing. Thank you for this example!
