How do I make a variable slider?

I don’t know how to make one, and what’s a “watcher block”???

when you create a new variable, right-click on the monitor and select ‘slider’.


then you can set the low and high values for the slider.

Hi, welcome to Snap!!

A watcher is the thing on the stage that looks like this:

When you make a variable with the “make a variable” button, you get a watcher automatically, and you can control its visibility with the checkbox next to the name in the Variables palette:

or using the


blocks.

To turn a watcher into a slider, right-click the watcher on the stage and choose “slider” from the menu.

The same menu will also let you control the range of values in the slider.

Thanks! Oh also, how do I make it so the speed of my rotation changes when I slide the variable slider around? (Sorry if this is confusing)

Is this what you mean?

Yea
