**Hey guys!**
I have a problem, I have attack script with cooldown and stuff in it, I've created basic combat system, everything works until I kill enemy, it destroys it as intended but then my attack timer stops counting until I select another enemy. Also I keep getting an error until I select first enemy because **target** field in attack script is empty at start.
Scripts:
**Attack Script:**
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class BasicAttack : MonoBehaviour {
public GameObject target; //target to attack
public int damage;
public float range = 4;
public float attackTimer;
public float cooldown = 2.0f;
public GameObject damageNumber;
public GameObject cooldownImage;
public Text cooldownText;
Targeting t;
UserInterface UI;
void Start () {
cooldownImage.SetActive(false);
attackTimer = 0;
t = FindObjectOfType();
UI = FindObjectOfType();
}
void Update () {
float distance = Vector3.Distance(target.transform.position, transform.position); //calculating distance
cooldownText.text = attackTimer.ToString("F0");
if (attackTimer > 0) {
attackTimer -= Time.deltaTime;
}
if (attackTimer <= 0) {
attackTimer = 0;
}
if (Input.GetKeyUp("1")) { //attack key
if (attackTimer == 0 && distance < range) {
Attack();
attackTimer = cooldown;
//damage numbers
var clone = (GameObject)Instantiate(damageNumber, t.selectedTarget.GetComponent().hitPoint.position, t.myTransform.rotation);
clone.GetComponent().damageNumber = damage;
}
else {
Debug.Log("Target is out of range!");
}
}
else {
cooldownImage.SetActive(true);
}
if (attackTimer == 0) {
cooldownImage.SetActive(false);
}
}
public void Attack() {
float distance = Vector3.Distance(target.transform.position, transform.position); //calculating distance
Vector3 dir = (target.transform.position - transform.position).normalized; //calculating direction
float direction = Vector3.Dot(dir, transform.forward); //calculating direction
if (distance < range) { //making player not be able to attack if too far
if (direction > 0) { //making player not be able to attack if target not in front of him
EnemyHealth eh = (EnemyHealth)target.GetComponent("EnemyHealth"); //getting enemy health
t.selectedTarget.GetComponent().TakeDamage(-damage); //adjusting enemy health
UI.infoText.text = "";
}
else {
Debug.Log("Target needs to be in front of you!");
}
UI.infoText.text = "";
}
else {
Debug.Log("Target is out of range!");
}
} //attack
}
**EnemyHealth Script:**
using UnityEngine;
using System.Collections;
public class EnemyHealth : MonoBehaviour {
public float maxHealth = 100;
public float curHealth = 100;
CombatTargetUI ct;
void Start () {
ct = FindObjectOfType();
}
void Update () {
TakeDamage(0);
}
public void TakeDamage (int ad) {
curHealth += ad;
if (curHealth <= 0) {
curHealth = 0;
/*ct.HideUI();*/
Die();
}
if (curHealth >= maxHealth) {
curHealth = maxHealth;
}
if (maxHealth <= 1) {
maxHealth = 1;
}
}
void Die () {
StartCoroutine(TimeToDestroy());
}
IEnumerator TimeToDestroy () {
yield return new WaitForSeconds(0.5f);
ct.HideUI();
Destroy(gameObject);
}
}
**Targeting Script:**
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class Targeting : MonoBehaviour {
public List targets;
public Transform selectedTarget;
public Transform myTransform;
CombatTargetUI ct;
void Start () {
targets = new List();
selectedTarget = null;
myTransform = transform;
ct = FindObjectOfType();
AddAllEnemies();
}
public void AddAllEnemies () {
GameObject[] go = GameObject.FindGameObjectsWithTag("Enemy");
foreach (GameObject enemy in go) {
AddTarget(enemy.transform);
}
}
public void AddTarget (Transform enemy) {
targets.Add(enemy);
}
void SortTargetsByDistance () {
targets.RemoveAll(target => target == null);
targets.Sort(delegate(Transform t1, Transform t2) {
return Vector3.Distance(t1.position, myTransform.position).CompareTo(Vector3.Distance(t2.position, myTransform.position));
});
}
void TargetEnemy () {
if (selectedTarget == null) {
SortTargetsByDistance();
selectedTarget = targets[0];
}
else {
int index = targets.IndexOf(selectedTarget);
if (index < targets.Count - 1) {
index++;
}
else {
index = 0;
}
DeselectTarget();
selectedTarget = targets[index];
}
SelectTarget();
}
void SelectTarget () {
ct.ShowUI();
selectedTarget.GetComponent().material.color = Color.red;
BasicAttack ba = (BasicAttack)GetComponent("BasicAttack");
ba.target = selectedTarget.gameObject;
}
public void DeselectTarget () {
if (selectedTarget != null) {
selectedTarget.GetComponent().material.color = Color.white;
}
selectedTarget = null;
}
void Update () {
if (Input.GetKeyDown(KeyCode.Tab)) {
TargetEnemy();
}
}
}
**I think that those are all scripts that might cause problem, can anyone help me? I'm desperate. :(**
