i'll add you in the credit section

You can use a slider variable.

CornDati

can you give an example please

Create a variable named “Volume” or something similar. Ensure it is visible on the stage.

Right-click on the variable on the stage and select “slider” from the drop-down.

The variable should now look like this:

If you want to change the minimum and maximum slider values, right-click on the slider and press “change slider range”.

Change the slider range using the popup, then press OK. If you want to use decimals, enter the number along with .00

Here's how I handled it:

If you make a slider variable from 0 to 100 called My Volume, then the code would be:

when green flag clicked
forever
set volume to (My Volume) %
end

As you move the slider the volume will change.

Note: You can call your variable Volume rather than My Volume.
I just wanted to avoid confusion in the example code.

Thanks,
That's what I would want to know,
But how can I covert it to a sprite?

Convert what to a sprite? Like make a slider sprite?

I think that what they're asking about is how to use sprites to mimic the slider effect without using the (honestly kind of glaring) orange variable slider. I recall that the project called Merge had a slider in it. You could go into the project's script to see how it was handled. (Warning: It may be a little laggy because of the sheer amount of code in it.)

I hope this helps you!

You can make a small circular sprite as the thing that can be dragged around in a slider. Then, you can use something like this to make the sprite draggable in the x axis with boundaries:

when green flag clicked
forever
if <<mouse down?> and <<(mouse x) > (start x)> and <(mouse x) < (end x)>>> then
set x to (mouse x)
set [Slider value v] to ((x position) - (start x))
end
end

To make it look more like a slider than a x-draggable circle, you should make a line in the background behind the circle. Also, keep in mind the slider value’s range is 0 to the difference between the start x and the end x, so unless the slider width is exactly 100, you might want to do some mapping.

Hi CornDati,

Something like this should work for you. I hard-coded it for a Range image that's 100 pixels tall (and “centered” at the bottom). If you need a specific image height, you should be able to scale the math in Slider. (Let me know if you need help scaling–maybe I'll generalize the demo to use a variable for the costume height. Same if you need it horizontal and can't figure out how to change it.)

I hope this helps. Happy to answer any questions.
