Question Stop Finding another target if there's a target present

I'm working on a tower defense game and currently building the tower target functionality.
Right now I find the closest enemy from the available enemies within the range and start shooting them.

However it switches target enemy in case one enemy comes close than the current target.
What I want is the once the target is found it should keep on shooting it and shouldn't switch the target.

Attaching the scripts.

Tower script

private void Update()
{
if (Input.GetMouseButtonDown(0))
{
ShowTowerRange();
}

GetClosestEnemy();
TurnTowardsEnemy();

if (timeBetweenBullets < attackInterval)

{
timeBetweenBullets += Time.deltaTime;
//print(attackInterval);

if (timeBetweenBullets >= attackInterval)
{
Shoot();
}
}
}

Shoot functionality

void Shoot()
{
GameObject bullet = Instantiate(towerProjectile, shootPoint.position, shootPoint.rotation);

timeBetweenBullets = 0f;
}

Projectile functionality

float speed = 5f;
Tower tower;
Transform target;

// Start is called before the first frame update
void Start()
{
tower = GameObject.FindGameObjectWithTag("Tower").GetComponent<Tower>();
target = tower.GetClosestEnemy().transform;
Destroy(gameObject, 2f);
}

private void Update()
{
transform.position = Vector3.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
//transform.forward * Time.deltaTime * speed;
}

 

ok, so what i would tweak is in the checkclosest function, assuming it's null from start. Once you get your closest target, you can only assign new target if target == null. you can set it to null once it gets out of range. p.s. try to use code tags. makes it much easier to read when posting code.)

 

Only skimmed over the unformatted code, but i generally agree with what was already said.

1. If you got a target, check if it's still in range and alive. Otherwise set it to null.
2. If you dont have a target, try to find a new one by whatever function. If you find one, set target.

That's all there is to it. The above can also be implemented directly in that order. Dont make it exclusive tho, as you may find out your target died and want a new one the same frame.

 

Thanks , it worked!
