Save and Retrieve UIDs from array

I plan on having a few way-points aligned with a grid around my layout. I figured that when I create them at start-up, I would save their UIDs in a 2D array in order to reference them easliy.

I run a Loop to create the objects and save their UIDs to an array in position (1, loopIndex). Then, I try to "Pick Instance with UID". For the UID, I use array.at(1, loopIndex), the same position I saved the objects to.

What am I doing wrong?

Maybe a downloadable .capx will help.

Thanks for any help!

Hi, i think its because the for loop runs first and doesnt include the pick. The point at which you pick the UID the loop has finished.

You can't pick the newly created objects until the next top-level event.

Thank you!

I was able to do what I wanted by shoving a "Trigger Once While True" event after the "On Start Of Layout".

Can I have multiple "On Start Of Layout" events? Is one way better than the other?

Yeah you could have the object picking loop in it's own 'on start of layout' event. Putting 'trigger once while true' on it's own is basically the same as 'on start of layout' I think.
