This structure describes the state of the physics engine at the current engine time. This structure is populated by calling TKQueryPhysicsEngine.

Syntax 

typedef struct tagPHYSICSENGINESTATE {
	DWORD cbSize; 
	DWORD dwTime;
	POINT ptPosition;
	LONG lVelocityX;
	LONG lVelocityY;
	BOOL fComplete;
} PHYSICSENGINESTATE;

Members

cbSize

Specifies the size of the PHYSICSENGINESTATE structure in bytes. You must set this value to sizeof(PHYSICSENGINESTATE).

dwTime

Specifies the current engine time in milliseconds.

ptPosition

Specifies the current animation position in pixels.

lVelocityX

Specifies the velocity along the X-axis in pixels per second.

lVelocityY

Specifies the velocity along the Y-axis in pixels per second.

fComplete

Specifies if the animation is complete.

Remarks

If cbSizeis not set to sizeof(PHYSICSENGINESTATE), TKQueryPhysicsEngine will return E_INVALIDARG.
