Slider set value

[mylinuxforwork]

Hi AGS users,

I have started to learn ags.

I have added a slider widget to a box and I am trying to set a default value to a slider.

Widget.Slider({
onChange: ({ value }) => print(value),
value: 3,
min: 0,
max: 10
}),

But the slider doesn't show 3 as value. It is still at 0.
How can I change it?

In addition I want to load the value from an bash script. How can I set this up?

Can you post a screenshot of how the outcome looks?

Hi, Stephan!

you can use ags Variables to achieve that:

...
// somewhere in your code
const sliderVar = Variable(3 /*initial value*/);

...
// in your slider code
onChange: ({ value }) => print(value),
value: sliderVar.bind(), // We're binding to our Variable.
min: 0,
max: 10
...

Now the slider value will be changing automatically every time you change the Variable value. You can do this by calling sliderVar.setValue(YOUR VALUE);. Also, you can get the value of the Variable: sliderVar.getValue();. Read the docs to understand it better.

In addition I want to load the value from an bash script. How can I set this up?

Something like, I suppose:

const proc = Utils.subprocess(
    // command to run, in an array just like execAsync
    ['bash', '-c', 'path-to-bash-script'],

    // callback when the program outputs something to stdout
    (output) => print(output),

    // callback on error
    (err) => logError(err),
)
