Is there anything like this available in puzzles already?

Hi
I always think if there is any chance of having a puzzle “do nothing”
many times I felt as if this puzzle or such provision is there then the logic setup would be more fool proof.
in my perspective there would be two functional meaning for this tiny puzzle asper its name

1. Literally do nothing after a specific condition is checked or tested.
2. Do not allow anything else while specific process or action is happening in the scene.

The second one sounds more useful especially while some thing is happening and users unwanted / unintentional click not to disturb the scene in to chaos till the initiated process completes.
