GUISliderModelInterval Property

public float Interval { get; set; }

Property Value

Setting this property to 0 allows the Slider to contain any value, while setting it to another number will allow the Slider to contain only multiples of this value.

For instance, setting Interval to 0.5 will only allow the Slider to contain multiples of 0.5 (e.g., 0, 0.5, 1, 1.5, etc.).
