Enemy character not moving to the 3rd waypoint. After moving to waypoint 2 it just stops and the idle animation plays. The character has a NavMeshAgent on it and it looks like the destination reached event is not being triggered when he gets to the waypoint. If anyone has had a situation like this before I would appreciate any information possible. I have been trying to figure out whats wrong for a few hours now and am starting to think it might not be any of the scripts.
here is the waypoint controller
using UnityEngine;
using UnityEngine.AI;
public class WaypointController : MonoBehaviour {
Waypoints[] waypoints;
public Transform target;
//NavMeshPath path;
int currentWaypointIndex = -1;
//private NavMeshAgent agent;
//EnemyCharacter enemy;
public event System.Action<Waypoints> OnWaypointChanged;
// Use this for initialization
void Awake () {
waypoints = GetWaypoints();
}
public void SetNextWaypoint() {
if (currentWaypointIndex != waypoints.Length)
currentWaypointIndex++;
if (currentWaypointIndex == waypoints.Length)
currentWaypointIndex = 0;
if (OnWaypointChanged != null)
OnWaypointChanged(waypoints[currentWaypointIndex]);
//Debug.Log("OnWaypointChanged == null: " + (OnWaypointChanged == null));
//Debug.Log("OnWaypointChanged != null: " + (OnWaypointChanged != null));
}
Waypoints[] GetWaypoints()
{
return GetComponentsInChildren<Waypoints>();
}
private void OnDrawGizmos()
{
Gizmos.color = Color.red;
Vector3 previousWaypoint = Vector3.zero;
foreach (var waypoint in GetWaypoints())
{
Vector3 waypointPosition = waypoint.transform.position;
Gizmos.DrawWireSphere(waypointPosition, .2f);
if (previousWaypoint != Vector3.zero)
Gizmos.DrawLine(previousWaypoint, waypointPosition);
previousWaypoint = waypointPosition;
}
}
}
Here is the EnemyPatrolPoints script
using UnityEngine;
[RequireComponent(typeof(AI_PathFinder))]
public class EnemyPatrolPoints : MonoBehaviour {
[SerializeField]
WaypointController waypointController;
[SerializeField]
float waitTimeMin;
[SerializeField]
float waitTimeMax;
AI_PathFinder pathfinder;
private void Start()
{
waypointController.SetNextWaypoint();
}
private void Awake()
{
pathfinder = GetComponent<AI_PathFinder>();
pathfinder.OnDestinationReached += Pathfinder_OnDestinationReached;
waypointController.OnWaypointChanged += WaypointController_OnWaypointChanged;
}
private void WaypointController_OnWaypointChanged(Waypoints waypoint)
{
pathfinder.SetTarget(waypoint.transform.position);
print("waypoint changed");
}
private void Pathfinder_OnDestinationReached()
{
SealForce_GameManager.Instance.Timer.Add(waypointController.SetNextWaypoint, Random.Range(waitTimeMin, waitTimeMax));
print("destination reached");
}
}
Here is the AI Pathfinder script`
using UnityEngine;
using UnityEngine.AI;
[RequireComponent(typeof(NavMeshAgent))]
public class AI_PathFinder : MonoBehaviour
{
[HideInInspector]
public NavMeshAgent agent;
public EnemyPatrolPoints enemyPatrolPoints;
[SerializeField] float distanceRemainingThreshold;
bool m_destinationReached;
bool destinationReached
{
get
{ return m_destinationReached; }
set
{
m_destinationReached = value;
if (m_destinationReached)
{
if (OnDestinationReached != null)
OnDestinationReached();
}
}
}
public event System.Action OnDestinationReached;
void Start()
{
agent = GetComponent<NavMeshAgent>();
//enemyPatrolPoints = GetComponent<EnemyPatrolPoints>();
}
public void SetTarget(Vector3 target)
{
agent.SetDestination(target);
}
void Update()
{
if (destinationReached)
return;
if (agent.remainingDistance < distanceRemainingThreshold)
destinationReached = true;
}
}
The lines
if (agent.remainingDistance < distanceRemainingThreshold)
destinationReached = true;
are never reached as long as destinationReached is true because of
if (destinationReached)
return;
You are setting it to true after the first waypoint is reached and then never reset it to false so your Update is always skipped in the future.
You should add it e.g. to
public void SetTarget(Vector3 target)
{
agent.SetDestination(target);
destinationReached = false;
}

So I have Ctr C Ctr V an Interaction System from YT channel.
I have perfectly copied line by line But the only issue was that he was using the old input system and used KeyPressedDown and keyPressedUp to make 2 boolean's which change according what state is the keypressed, I tried to mimic it with new Input system by making it from a button to a Axis value which follows the logic of if its ClickedAxis>0.4 its true and ClockedAxis==0 false, as a quick press it worked so I was happy BUT here comes the bug
My if statement is Being Spammed Constantly like none stop. My statement basically say's that if the Interacting is true Do :
bool interacting;
If(interacting)
{
float HoldingDownTimer+=Time.DeltaTime;
if(HoldingDownTimer>=5)
{
//Do your task;
}
}
but When I run the statement For some reason it prints 0.0110823 values which are stuck at that range of number's no lower no higher, My theory is that its been spam called.
Here's the Script

Well without parsing through your entire code:
once
HoldingDownTimer >= 5
is true you still keep adding more time in the next frame so the condition is still true in the next frame => you will keep calling it all the following frames as well.
You could introduce a flag somewhat like e.g.
private bool alreadyCalled;
and then
if(interacting)
{
if(!alreadyCalled)
{
HoldingDownTimer += Time.DeltaTime;
if(HoldingDownTimer >= 5)
{
alreadyCalled = true;
//Do your task;
}
}
}
else
{
alreadyCalled = false;
}
As far as I understood your code I think:
I found the issue in it actually you are checking if the 'm_holdTimer' >= 'holdDuration' then perform interaction and you are making it equal to 0 on click start and click end.
So it means if the player has continuously held the button then it will not reset 'm_holdTimer'... so it will continue to call the function recursively because player hasn't actually ended the click so there is not any single function which is reseting 'm_holdTimer' to 0. still if you didn't get my point just copy this function and paste it instead of your own and see if it works, if it do work then you can check the difference between line of code then you'll understand it for sure.
void CheckForInteractableInput()
{
if (interactionData.isEmpty())
{
return;
}
if (interactionInputData.InteractedClicked)
{
m_interacting = true;
m_holderTimer = 0f;
}
if (interactionInputData.InteractedReleased)
{
m_interacting = false;
m_holderTimer = 0f;
}
if (m_interacting)
{
if (!interactionData.Interactable.IsInteractible)
return;
if (interactionData.Interactable.HoldInteract)
{
m_holderTimer += Time.deltaTime;
Debug.Log(m_holderTimer);
if (m_holderTimer >= interactionData.Interactable.holdDuration)
{
m_holderTimer = 0f;
interactionData.Interact();
m_interacting = false;
}
}
else
{
interactionData.Interact();
m_interacting = false;
}
}
}

now the bullets firing up the air and i want the bullets to fire to a target with physics.
the main goal later is to make some kind of side mission where the player third person view should shoot on object and if and when hitting the object the object will fall down and then the player will be able to pick it up.
I hope you could help me. I want my enemy object to stop after a few seconds, and then move on after another few seconds. So far everything works, but the objects jump into the top right corner a few seconds after they are stopped. Can you give me some tips on what I did wrong and how I can do it better.

I'm creating a FPS game and I have the following issue:
Sometimes, when I shoot at the enemies the hit is not recognized, even if the player is shooting in front of them. However, when they attack the player, the hit is recognized normally.
They have a box collider and a rigidbody attached to them.
This script is attached to the player:
using System.Collections.Generic;
using UnityEngine;
public class DisparaArma : MonoBehaviour
{
private GerenciaArma gerenciaArma;
public float nDisparo = 15f;
private float TempoProximoDisparo;
public float damage = 20f;
private Animator ZoomCameraIn;
private bool zoomed;
private Camera Maincamera;
private GameObject mira;
// Start is called before the first frame update
void Start()
{
gerenciaArma = GetComponent<GerenciaArma>();
ZoomCameraIn = transform.Find(Tags.LOOK_ROOT).transform.Find(Tags.ZOOM_CAMERA).GetComponent<Animator>();
mira = GameObject.FindWithTag(Tags.MIRA);
Maincamera = Camera.main;
}
// Update is called once per frame
void Update()
{
Atira();
ZoomInAndOut();
}
void Atira()
{
if (Input.GetMouseButtonDown(0))
{
if(gerenciaArma.SelecionaArma().tipoBala == WeaponBulletType.BULLET)
{
gerenciaArma.SelecionaArma().AnimacaoTiro();
DisparaBala();
}
}
}
void ZoomInAndOut()
{
if (gerenciaArma.SelecionaArma().mira_tipo == TipoMira.AIM)
{
if (Input.GetMouseButtonDown(1))
{
ZoomCameraIn.Play(Animacoes.ZOOM_IN_ANIM);
// gerenciaArma.SelecionaArma().Aim(true);
mira.SetActive(false);
print("VaiZoom");
}
if (Input.GetMouseButtonUp(1))//
{
ZoomCameraIn.Play(Animacoes.ZOOM_OUT_ANIM);
//gerenciaArma.SelecionaArma().Aim(false);
mira.SetActive(true);
}
}
}
void DisparaBala()
{
RaycastHit hit;
if(Physics.Raycast(Maincamera.transform.position, Maincamera.transform.forward, out hit))
{
if (hit.transform.tag == Tags.ENEMY_TAG)
{
hit.transform.GetComponent<ScriptVida>().DanoAplicado(damage);
}
}
}
}
And this one is attached to the enemies:
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
public class ScriptVida : MonoBehaviour
{
private IndioAnimações indio_Anim;
private NavMeshAgent navAgent;
private IndioController indio_Controller;

}

{
indio_Controller.chase_Distance = 50f;
}
}
if (vida <= 0)
{
JogadorMorre();
morto = true;
print(vida);
}
}
void JogadorMorre()
{
if (is_Cannibal)//
{
GetComponent<Animator>().enabled = false;
GetComponent<BoxCollider>().isTrigger = false;
GetComponent<Rigidbody>().AddTorque(-transform.forward * 50f);
indio_Controller.enabled = false;
navAgent.enabled = false;
indio_Anim.enabled = false;
}
if (is_Tiger)
{

indio_Controller.enabled = false;

indio_Anim.enabled = false;
}
if (is_Player)
{
GameObject[] enemies = GameObject.FindGameObjectsWithTag(Tags.ENEMY_TAG);
for (int i = 0; i < enemies.Length; i++)
{
enemies[i].GetComponent<IndioController>().enabled = false;
}
GetComponent<Movimentação>().enabled = false;
GetComponent<DisparaArma>().enabled = false;
GetComponent<GerenciaArma>().SelecionaArma().gameObject.SetActive(false);
}
if (tag == Tags.PLAYER_TAG)
{
Invoke("RestartGame", 3f);
}
else
{
Invoke("TurnOffGameObject", 3f);
}
}
void RestartGame()
{
UnityEngine.SceneManagement.SceneManager.LoadScene("Gameplay");
}
void TurnOffGameObject()
{
gameObject.SetActive(false);
}
}
I think the problem is related to the box collider.
How could I solve this guys?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Teleport : MonoBehaviour {
public GameObject player;
public Camera mainCamera;
public Camera firstCam;
public Camera camera;
private List<GameObject> TeleportBooths;
private TeleportationsCore tc;
private void Start()
{

TeleportBooths = new List<GameObject>();
TeleportBooths = gos.PrefabsList();
firstCam.enabled = false;
mainCamera.enabled = false;
camera.enabled = true;
for (int i = 0; i < TeleportBooths.Count; i++)
{
TeleportBooths[i].AddComponent<TeleportationsCore>();
}
tc = GetComponent<TeleportationsCore>();
WorkingBooth();
}
private void WorkingBooth()
{
player.transform.position = TeleportBooths[tc.WorkingBooth()].transform.position;
camera.transform.position = new Vector3(TeleportBooths[tc.WorkingBooth()].transform.position.x - 10, TeleportBooths[tc.WorkingBooth()].transform.position.y + 10, TeleportBooths[tc.WorkingBooth()].transform.position.z);
camera.transform.LookAt(TeleportBooths[tc.WorkingBooth()].transform);
}
private void Update()
{
WorkingBooth();
}
}
I'm doing:
tc = GetComponent<TeleportationsCore>();
But tc is null.
And the script i want to access to:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TeleportationsCore : MonoBehaviour
{
public float spinSpeed = 2.0f;
private bool rotate = false;
private bool exited = false;
private int boothIndex = 0;
private void Start()
{
WorkingBooth();
}
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "Player")
{
Debug.Log("Player entered the hole");
rotate = true;
}
}
private void OnTriggerExit(Collider other)
{
if (other.gameObject.tag == "Player")
{
Debug.Log("Player exited the hole");
rotate = false;
exited = true;
}
}
void Rotate()
{
if (rotate)
{
if (spinSpeed == 350)
{
rotate = false;
exited = true;
boothIndex++;
WorkingBooth();
}
else
{
transform.Rotate(Vector3.up, spinSpeed * Time.deltaTime);
spinSpeed += 1f;
}
}
if (rotate == false && exited == true)
{
transform.Rotate(Vector3.up, spinSpeed * Time.deltaTime);
if (spinSpeed > 0.0f)
spinSpeed -= 1f;
}
}
public int WorkingBooth()
{
return boothIndex;
}
private void Update()
{
Rotate();
}
}
What i want is after i attach the script to all gameobject to get access the function WorkingBooth on TeleportationsCore.
And i don't want to attach the TeleportationsCore to the GameObject Teleport is attached on. So what other ways i have to access the WorkingBooth on TeleportationsCore ? Making the WorkingBooth public static ?
Change this:
for (int i = 0; i < TeleportBooths.Count; i++) {
TeleportBooths[i].AddComponent<TeleportationsCore>();
}
to:
TeleportationsCore[] tCores = TeleportBooths.Select(booth => booth.AddComponent<TeleportationsCore>());
Now just pick the core you want from the list.
Attach the TeleportationsCore script to empty game object. To get its reference, use this:
TeleportationsCore core = FindObjectOfType<TeleportationsCore>();
Use it for example in the Start function, as it is a bit slow.
You can find more in documentation.
