====== Fixing the Camera to an Object manually using a Clock ======
If you wish the camera to be fixed on a moving object, you will need to use code to update it regularly. The camera's x and y coordinates are copied from the object, but not the z coordinate.


===== Code =====

<code=c>
void orxFASTCALL Update(const orxCLOCK_INFO *_pstClockInfo, void *_pContext)
{
	orxVECTOR cameraPosition = { 0,0,0 };
	orxCamera_GetPosition(camera, &cameraPosition);

	orxVECTOR heroPosition= { 0,0,0 };
	orxObject_GetPosition(hero, &heroPosition);

	cameraPosition.fX = heroPosition.fX;
	cameraPosition.fY = heroPosition.fY;
	orxCamera_SetPosition(camera, &cameraPosition);
...
}

orxSTATUS orxFASTCALL Init()
{
...

  orxClock_Register(orxClock_Get(orxCLOCK_KZ_CORE), Update, orxNULL, orxMODULE_ID_MAIN, orxCLOCK_PRIORITY_LOWER);
...
</code>

Please note the use of ''orxCLOCK_PRIORITY_LOWER'' instead of ''orxCLOCK_PRIORITY_NORMAL''. This mode ensures the camera is updated **//after//** all the objects which will ensure a rock solid lock.
