IInertiaProcessor::DesiredDeceleration property

The DesiredDeceleration property specifies the desired rate at which translation operations will decelerate.

This property is read/write.

Syntax


HRESULT put_DesiredDeceleration(
  [in]   FLOAT decleration
);

HRESULT get_DesiredDeceleration(
  [out]  FLOAT *decleration
);

Property value

The desired rate at which translation operations will decelerate.

Error codes

Returns S_OK on success; otherwise, returns an error code such as E_FAIL.

Remarks

DesiredDeceleration and DesiredDisplacement are mutually exclusive. If one is set, the other should be NaN.

If inertia processing has already started, setting DesiredDeceleration will reset the inertia engine to the initial state with new deceleration value applied.

Call this function to set the initial state of inertia. You would call this function most likely during the ManipulationCompleted event of the IManipulationProcessor or in the constructor of the IInertiaProcessor interface.
