====== ScrollObject following another ScrollObject ======

This routine will use the ''Update'' function of a ScrollObject, physics and some orxVECTOR math to always try to follow another object.

<code=c>

void Enemy::Update(const orxCLOCK_INFO &_rstInfo)
{
	orxOBJECT *enemyObject = this->GetOrxObject();

	orxVECTOR enemyPosition = orxVECTOR_0;
	this->GetPosition(enemyPosition, orxTRUE);

	orxVECTOR playerPosition = orxVECTOR_0;
	playerPosition = karbon_game::GetInstance().GetPlayerPosition(); //you'll need to implement this function in your game code

	orxVECTOR directionToShip = orxVECTOR_0;
	orxVector_Sub(&directionToShip, &playerPosition, &enemyPosition);

	orxVECTOR speedTowardsShip = orxVECTOR_0;
	orxVector_Normalize(&speedTowardsShip, &directionToShip);
	orxVector_Mulf(&speedTowardsShip, &speedTowardsShip, 0.3);

	orxObject_ApplyImpulse(enemyObject, &speedTowardsShip, orxNULL);
}
