Guard Behaviour : Rotate to Initial Position - My Solution

#1

Initially, I wanted to refactor the “InAttackRangeOfPlayer()” bool function to take a float and Vector 3 argument and rename it “InRange” like this

        bool InRange(Vector3 position,float range)
        {
            float distanceToPlayer = Vector3.Distance(transform.position, position);
            return distanceToPlayer < range;
        }

This way we can repurpose the function to calculate any distance from any position. However, I didn’t know if this function will be used in a future lecture and decided to duplicate and rename it instead

        bool InGuardingRange()
        {
            float distanceToPlayer = Vector3.Distance(transform.position, guardPosition);
            return distanceToPlayer < 0.1f;
        }

In the Update, If/else statement I simply added this

void Update()
        {
            if (health.IsDead()) return;

            if (InAttackRangeOfPlayer() && fighter.CanAttack(player))
            {
                fighter.Attack(player);
            }
            else
            {
                mover.StartMoveAction(guardPosition);
                if (InGuardingRange())
                {
                    transform.rotation = Quaternion.RotateTowards(transform.rotation, guardRotation, 5);
                }
            }

        }

                if (InGuardingRange())
                {
                    transform.rotation = Quaternion.RotateTowards(transform.rotation, guardRotation, 5);
                }

I made a new Quaternion guardRotation and cached the initial rotation in Start with " guardRotation = transform.rotation; "
By using Quaternion.RotateTowards we can smoothly rotate back to the initial position and make it look more natural.

Try Slerping for smoother rotation

void OnTriggerEnter(Collider other)
    {
        // Store the collider information only if it has a CombatTarget component
        CombatTarget target = other.GetComponent<CombatTarget>();
        if (target != null)
        {
            combatTarget = target;
        }
    }

    void OnTriggerExit(Collider other)
    {
        // Reset the combatTarget only if it's the current target
        CombatTarget target = other.GetComponent<CombatTarget>();
        if (target == combatTarget)
        {
            combatTarget = null;
        }
    }
