SetPhysicsEngineUserTime (Compact 2013)

3/28/2014

This function sets the current time stamp of the physics engine object in relation to the start of an animation. You can use this function to simulate a set sequence of time steps, for example, to check an animation plan or to reproduce specific testing conditions.

You must create the physics engine in PHYSICSENGINE_FLAG_USERTIME mode to use this function.

Syntax

HRESULT SetPhysicsEngineUserTime(
    HPHYSICSENGINE hEngine,
   DWORD dwTime
);

Parameters

• hEngine
  [in] A handle to the physics engine object.

• dwTime
  [in] The time stamp, in milliseconds, from the start of the animation.

Return Value

• S_OK
  Indicates that the physics engine time is successfully set.

• E_INVALIDARG
  Indicates that the hEngine handle is invalid.

• E_UNEXPECTED
  Indicates that the physics engine is not in PHYSICSENGINE_FLAG_USERTIME mode.

Remarks

When you create the physics engine in PHYSICSENGINE_FLAG_USERTIME mode, the time is set to 0 (zero).

You must call SetPhysicsEngineTime with a time stamp that is greater than the current time stamp of the physics engine, otherwise the physics engine calculates incorrect stopping points for the animation.
