IInertiaProcessor::InitialVelocityX property

The InitialVelocityX property specifies the initial movement of the target object on the horizontal axis.

This property is read/write.

Syntax


HRESULT put_InitialVelocityX(
  [in]  FLOAT velocity
);

HRESULT get_InitialVelocityX(
  [out] FLOAT *velocity
);

Property value

The initial movement of the target on the horizontal axis.

Error codes

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

Remarks

If Inertia processing has already started, setting InitialVelocityX will reset the inertia engine to the initial state with new velocity values 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.
