Questions & Answers
1

Im using a horizontal slider to change a value.Say the start point is 'A' and the end point is 'B'.I want the slider to only move from A to B and restrict movement from B to A.

Any ideas on how i could get that to work?

I'd probably just do it in OnGUI(), e.g. (untested):

float newValue = GUI.HorizontalSlider(..., currentValue, ...);
currentValue = Mathf.Max(currentValue, newValue);

Poll your slider in the Update() Method.

If the value of the slider goes below the current slider value:

if(newSliderValue < currentSliderValue) {
      newSliderValue = currentSliderValue;
} else {
      currentSliderValue = newSliderValue;
}

Set it to the current value instead of the new one.
