示例3: offsetPursuit

Vector4 SteeringBehavior::offsetPursuit(Handle &p_leader, Vector4 &offset) {
	MovingObject* leader = dynamic_cast<MovingObject*>(theWorld.get(p_leader));

	if (leader == nullptr) {
		// Leader does not exist anymore
		off(BehaviorType::offset_pursuit);
		return Vector4(0, 0, 0);
	}

	// calculate the offset's position in world space
	Vector4 WorldOffsetPos = leader->getPosition() + offset;

	Vector4 ToOffset = WorldOffsetPos - owner->getPosition();

	// The lookahead time is propotional to the distance between the leader
	// and the pursuer; and is inversely proportional to the sum of both
	// agent's velocities
	float LookAheadTime = ToOffset.length() / (owner->getMaxSpeed() + leader->getSpeed());

	// Arrive at the predicted future position of the offset
	return arrive(WorldOffsetPos + leader->getVelocity() * LookAheadTime, fast);
