How do I compare objects instance variables?

Hello, very new to construct, and I have what might be a really dumb question but I cannot for the life of me figure out how to do a compare for an object's instance variable.

I have a Player object with a health variable, and from my understanding to make the comparison (if health <= 0) I'd need to add an action to the player and I'd find compare the value in the instance variable section. However, that's not the case as you can see from the screenshot.

Am I looking in the wrong place? Is this not available in the free edition?

Thank you in advance.

this variable comparison has to be done in the event, in the action you can only add, subtract or define

See i knew it was a dumb question, thnk you very much that was it
