Hi everyone, I have some doubts regarding the correct use of "trigger once while true" in a situation like the one in my example. Basically, if I am not mistaken, if I need to do something only once when an overlap occurs between two objects, I am forced to use "trigger once while true". Reading various posts on the forum, however, I seem to have understood that it is better not to use it.
If I use method 1 instead of method 2, is that more correct? And how can I get the result of method 1 without using the collision as a trigger event, which in some cases (for example when my objects use solid behavior or physics) can create other problems that are more complex for me to solve? I would have managed all the logic with variables, but in this case I was unable to get the desired result as construct continues to execute the code indefinitely. I hope I have explained myself well despite the use of google translate.
Thanks to all those who will participate in the discussion.

You didn't really say the purpose of the overlap but since you are using drag and drop and I am imagining some kind of crafting mechanic, you can add 'on drop' so it's a trigger once to the overlapping conditions. If you grab the UID of the item you picked up you can compare the other item that is overlapping with it 'on drop'.

The method you suggest works.
For my example, in fact, I took a cue from an inventory template I'm working on. But probably my example is wrong because I didn't think that with on drop the problem is solved.
With my question basically I wanted to understand if it is true that the use of "Trigger once while true" (in a situation like the one in the example) is:
1) absolute evil and is to be avoided always and in any case, otherwise I could commit a crime punishable with humiliation and torture by more capable programmers than me.
2) they are just rumors and I can therefore simplify my life and use it if necessary without worrying too much that nothing breaks out.
3) it is only a matter of elegance to be able not to use it, but if necessary even the good ones use it
Anyway thanks for the answer Lionz, if it had been a real problem as always you would have guessed the solution even despite the problem explained wrongly.
