Knob Control component as seen in the Scene Inspector


KnobControl takes the local rotation of its slot around a specified axis and applies it proportionally to a floating point value.

Fields

Fields
Name Type Description
persistent Bool Determines whether or not this item will be saved to the server.
UpdateOrder Int Controls the order in which this component is updated.
Enabled Bool Controls whether or not this component is enabled.
Target IField`1<Float> A field to set with the knob's value.
Callback Action`1<Float> A delegate that is called with the knob's value change.
RotationAxis Float3 The axis around which to measure the slot's local rotation.
Rate Float The proportional effect of the knob, in values per full (360-degree) rotation.
Min Float The minimum value for the knob.
Max Float The maximum value for the knob.
_lastRotation Float (internal, read-only) Used in determining the rotational change.
_lastAxis Float3 (internal, read-only) Used if the RotationAxis changes.
_lastUser User (internal, read-only) The user who last rotated the slot.

Usage

As the local rotation of this component's slot changes, the knob's value is updated according to how much it has rotated about the RotationAxis. The amount the value changes is determined by the change in rotation (measured in fractions of a full rotation, so for example a change of one degree would be 1/360), multiplied by the Rate.

Note that the value field is not driven. This means it is synced to all users, and can be written to at any time.

This component is most useful when coupled with a Joint to restrict the slot's rotation to be only around the rotation axis.
