How do I reference multiple instances within an event?

So yeah, I want one specific instance to trigger stuff with another instance within an event. I tried this but it didn't work:

Any ideas on how to do it?

Another question: Can we do local variables within functions? Don't think we can but thought I'd ask. EDIT: Yes we can, boyah! Need to check the manual more

You will never get Character with UID 45 picked, because you already picked 201. Other issues aside, you must do a 'System:Pick all Character' before the Pick instance with UID 45.

Try it and see (I see you've already edited your post about this)

Thanks! I'm using local variables to check conditions of different instances right now and it works fine. Also just discovered I can pass variables to functions. So much stuff right beneath my nose that I'm missing

I have to say, dealing with objects by UID is not normally recommended.. as they will usually be different every run.

Yeh I know, I normally use an instance variable to identify separate instances. I just used the "pick instance" condition in this example for clarity

Also just discovered I can pass variables to functions.

And they can return a value too
