Hello.
I want a script to be applied when a button is pressed.
Is it correct to put the javascript under a condition, like a capture image?
Yes, in your situation, you can use it as a subevent.
The Javascript event is just like any event. If it’s all the way to the left it will run on every frame. If it’s a subevent, it will only be triggered when all of the previous conditions are true.

It’s recommended to put JS code in extensions instead of directly in the main events to keep things tidy.
