A Notched Scroll Selector

ge-b

How would you make a custom scroll bar like a slider variable with only a few numbers so it ‘slides’ in segments?

Edit: Unresolved!

What I want:

define Segment Scroll from (x left) to (x right) with (no. notches) notches

https://scratch.mit.edu/projects/239550127/ is my attempt, but the mouse rounding just isn't right. It gets more obvious the less notches you put.

If you want the variable slider to only have a few numbers, you can right click it in the stage and select ‘set variable min and max’.
Then you can set it to only slide between 1-4 or whatever numbers you want.

Not my question. A ‘custom’ slider.

bump.

expanding on what I first said…

when green flag clicked
go to x: (0) y: (0)
forever 
  if <<(distance to [mouse-pointer v]) < [50]> and <mouse down?>> then 
    go to x: ((round ((mouse x) / (20))) * (20)) y: (0)
    if <(x position) < [-100]> then 
      set x to (-100)
    end
    if <(x position) > [100]> then 
      set x to (100)
    end
  end
end

Please post in a more appropriate forum and create your own topic there - eg Requests.

    end
  end
end

A bit messy for numbers that don't divide into each other. Any better options?

I looked at your code, does this work…

define segment scroll (notch) (left) (right)
set [notch dist v] to (((right) - (left)) / (notch))
go to x: ((round ((mouse x) / (notch dist))) * (notch dist)) y: (0)
if <(x position) < (left)> then 
  set x to (left)
end
if <(x position) > (right)> then 
  set x to (right)
end

Output is

(x position)

  set x to (left)
end
if <(x position) > (right)> then 
  set x to (right)
end

Output is

(x position)

Gives one more notch than the input. Tried replacing the part with a

((notch)-(1))

but has the same messiness problem, which is caused by the method of simply setting the x position to the min or the max whenever it's outside the range.

I give up. Gonna ram it out of myself.

I remember seeing this in a project. I don't remember the project, but I saw it in use from littlebuny's 3d engine.

when [up ] key pressed
if <not <key [up ] pressed?>> then
broadcast [do what you want if you scroll up ]
end

when [down ] key pressed
if <not <key [down ] pressed?>> then
broadcast [do what you want if you scroll down ]
end

Basically, the mouse wheel is detected instead of the arrow key.
