Math on a screen [Solved]

[DoubleProlix]

I'm setting up a HUD, and I want it to display the ratio of two variables:

text "Ratio: [x]"

works fine to display the value of var1. However, if I try to display the ratio of x to y:

text "Ratio: [x / (x + y)]"

it treats the equation like a name and throws an exception.

I don't need the screen to change the game state, just to display the statement's output. Can I do this, or do I need to create another variable for the ratio that is updated whenever x or y is changed? Or is there some simpler way to make this work?

The square bracets in text is used to show value of a variable not to calculate it. Try

Code: Select all

screen scr_name():
    $ res = x / (x + y)
    text "Ratio: [res]" 

[Remix]

Code: Select all

screen a:
    $ x,y = 7.0, 12.0
    text "Ratio: {:.03f}".format( x / (x + y) )

Alternatively, pyformat can be used ( the :.03f means zero pad to 3 decimals )
Remember to cast x and y to floats rather than integers to avoid python pre 3 rounding the result

Right, that works, thanks.
