I stumbled upon this and thought I'd experiment with getting background images to show behind the text, but no joy. Unless I'm completely misunderstanding it. I've basically done this in the start script:

setbackgroundopacity = true
backgroundopacity = 0.5

But it does zilch.

Perhaps you need:

game.setbackgroundopacity = true
game.backgroundopacity = 0.5

You can also just call:

SetBackgroundOpacity(0.5)

The first suggestion does nothing, the second produces an error.

Or maybe I think these functions do something different than I think they do?

Wait. I think the second suggestion works if I call it from clearscreen.

Ok, it works, cheers.
