Expression for this?

Is there a system expression for accessing the "current" value of a global or local variable? No, not the value initially when the first layout is run. I mean accessing the current value when an event is run.

Because, I made a HP bar using a global variable, some expressions and and width adjustments via events every tick. I only came across one bug from 20 minutes of testing:

Player starts out in layout one.

Player takes damage.

Player moves to layout two, via portal; HP bar doesn't change.

Player moves back to layout one via same portal; HP bar suddenly becomes empty.

Fixed the bug, but I still like to know if such an expression exists.

Variables in the manual

Extract from the how do I FAQ

Also in your case, the problem doesn't come from variables.

It's rather the display of the health bar that's the issue I think.

Several solutions exists. For now I'd go with the global property.

LaDestitute, the name of a variable in an expression gets its current value, I think you must be confused somehow...
