Hello,

I’m trying the create a menu with that uses the scrollbar. I set the scrollbar to a number of steps, when the step changes something happens > if (scrollbar.step = 1) {something}. But how can i detect or check the current step number ?

Greet, Anne

You will have to calculate it yourself. Scrollbar has no min or max value, so scrollbar.Value Range is 0.0f → 1.0f.

To get the position you would have to do something like:
Untested

Scrollbar scrollBar = GetComponent<Scrollbar>();
// initialize the scrollbar
int steps = 5;
scrollBar.numberOfSteps = steps;
scrollBar.onValueChanged.AddListener((value) =>
{
    // round to int to catch floating point problems.
    int currentStep = Mathf.RoundToInt(value / (1f / (float) bar.numberOfSteps));
});

there is an update to this code. it stops working after the half.

int currentStep = Mathf.RoundToInt(value / (1f / (float)bar.numberOfSteps));
if (value > 0.5)  currentStep -= 1;

use this

  • int currentStep = Mathf.RoundToInt(value / (1f / (float)bar.numberOfSteps));
  • if (value >= 0.5) currentStep -= 1;
