how do I test for conditions on and trigger them on only one single object

so, currently I have a small system in place where if you are in "build mode" have your mouse cursor over one of the machines in the game, and press "F" it'll turn off the machine and it will stop producing whatever it makes until its turned back on again.

I do this by way of simple detection, but with that comes a problem.

Lets say I have mutable of one machine, it ends up triggering all of them to turn off, which in some cases can be counterintuitive.

How would I make it so it can detect the one certain object, and only trigger it for that one object.

thanks!

By picking, and the condition 'mouse cursor is over object' should be enough to pick that one instance of the object. If you already have that event and it's not working please share a screenshot of the events.

OMG I just figured it out, I'm ashamed to call myself a developer after this lol

it wasn't an instance variable

I was using a global variable

what is wrong with me
