The game is not restarting after the player dies

I'm making this flappy bird replica but instead of a bird it's a rocket.
The controlls are different however the idea is the same.
I have setup a GameManager script:
using UnityEngine;
public class GameManager : MonoBehaviour
{
// Script Refrences
public BarrierSpawnner spawnner;
public MainMen menu;
public MoveLeft moveLeft;
public rockeyMovement movement;
void Start()
{
spawnner.StartedGame = false;
movement.dead = false;
spawnner.StartedGame = false;
movement.rend.enabled = true;
}
void Update()
{
if (spawnner.StartedGame)
{
menu.menuOn = false;
}
if (movement.dead == true)
{
spawnner.StartedGame = false;
}
if (spawnner.StartedGame == false)
{
menu.menuOn = true;
}
}
}
And a Movement Script:
using UnityEngine;
public class rockeyMovement : MonoBehaviour
{
// Variables
private float gravity;
private Vector2 startPos;
public bool dead;
// Refrences
public Rigidbody2D rb;
public BarrierSpawnner spawnner;
public Renderer rend;
public MainMen menStart;
public static rockeyMovement Instance { get; private set; }
void Start()
{
Instance = this;
startPos = transform.position;
rb = GetComponent<Rigidbody2D>();
gravity = rb.gravityScale;
rb.gravityScale = 0;
rend = GetComponent<Renderer>();
}
void OnCollisionStay2D(Collision2D collision)
{
dead = true;
gravity = rb.gravityScale;
rb.gravityScale = 0;
startPos = transform.position;
}
void Update()
{
if (spawnner.StartedGame)
{
rb.gravityScale = 2;
}
if (spawnner.StartedGame == false)
{
transform.position = new Vector2(0, 0);
}
Vector2 vel = rb.velocity;
float ang = Mathf.Atan2(vel.y, 10) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(new Vector3(0, 0, ang - 90f));
if (Input.GetButton("Jump"))
{
rb.AddForce(Vector2.up * gravity * Time.deltaTime * 1000f);
}
}
}
As well as a MenuScript:
using UnityEngine;
public class MainMen : MonoBehaviour
{
public BarrierSpawnner spawnner;
public GameObject CanvasObject;
public bool menuOn;
void Update()
{
if (menuOn)
{
CanvasObject.GetComponent<Canvas> ().enabled = true;
}
}
public void Go()
{
spawnner.StartedGame = true;
CanvasObject.GetComponent<Canvas> ().enabled = false;
}
}
The game starts out normally in the correct way, the problems pop up the moment the player dies. When the player comes in contact with the obstacles I have the script set a bool to true "dead". And when "dead" is true the menu pops back again however, I you cannot interact with it and the page stays like that.
How do I fix this issue?
Is my logic right?
If not, where did I go wrong?

Don't disable Canvas component. Instead, create a panel with buttons on it and activate this panel when needed. Keep it deactivated otherwise.

Juggled player animation on the slopes in Unity

I have another issue with my animator in 2D.
Currently i have only few slopes in game, but it annoys me, because i don't know how to make animation work properly on them. This is one example:
As you can see, there is little slope. Now how my Animator looks like:
The code now looks like it:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;
using System;
public class PlayerMovementScript : MonoBehaviour
{
[SerializeField] float runSpeed;
[SerializeField] float jumpSpeed;
[SerializeField] float climbSpeed;
Vector2 moveInput;
Rigidbody2D playerRigidbody;
Animator playerAnimator;
CapsuleCollider2D playerCapsuleCollider;
float gravityScaleAtStart;
void Start()
{
playerRigidbody = GetComponent<Rigidbody2D>();
playerAnimator = GetComponent<Animator>();
playerCapsuleCollider = GetComponent<CapsuleCollider2D>();
gravityScaleAtStart = playerRigidbody.gravityScale;
}
void Update()
{
Run();
FlipSprite();
ClimbLadder();
Falling();
}
void OnMove(InputValue value)
{
moveInput = value.Get<Vector2>();
Debug.Log(moveInput);
}
void OnJump(InputValue value)
{
if (!playerCapsuleCollider.IsTouchingLayers(LayerMask.GetMask("Ground"))) { return; }
if (value.isPressed)
{
playerRigidbody.velocity += new Vector2(0f, jumpSpeed);
}
}
void Run()
{
Vector2 runVelocity = new Vector2(moveInput.x * runSpeed, playerRigidbody.velocity.y);
playerRigidbody.velocity = runVelocity;
bool playerHasHorizontalSpeed = Math.Abs(playerRigidbody.velocity.x) > Mathf.Epsilon;
if (playerCapsuleCollider.IsTouchingLayers(LayerMask.GetMask("Ground")))
{
playerAnimator.SetBool("isRunning", playerHasHorizontalSpeed);
} else
{
playerAnimator.SetBool("isRunning", false);
}
}
void FlipSprite()
{
bool playerHasHorizontalSpeed = Math.Abs(playerRigidbody.velocity.x) > Mathf.Epsilon;
if (playerHasHorizontalSpeed)
{
transform.localScale = new Vector2(Mathf.Sign(playerRigidbody.velocity.x), 1f);
}
}
void ClimbLadder()
{
if (!playerCapsuleCollider.IsTouchingLayers(LayerMask.GetMask("Climb"))) {
playerRigidbody.gravityScale = gravityScaleAtStart;
playerAnimator.SetBool("isClimbing", false);
playerAnimator.SetBool("isClimbingIdle", false);
return;
}
Vector2 climbVelocity = new Vector2(playerRigidbody.velocity.x, moveInput.y * climbSpeed);
playerRigidbody.velocity = climbVelocity;
playerRigidbody.gravityScale = 0;
bool playerHasVerticalSpeed = Math.Abs(playerRigidbody.velocity.y) > Mathf.Epsilon;
playerAnimator.SetBool("isClimbing", playerHasVerticalSpeed);
playerAnimator.SetBool("isClimbingIdle", !playerHasVerticalSpeed);
}
void Falling()
{
if (
playerCapsuleCollider.IsTouchingLayers(LayerMask.GetMask("Climb"))
|| playerCapsuleCollider.IsTouchingLayers(LayerMask.GetMask("Ground"))
) {
playerAnimator.SetBool("isJumping", false);
playerAnimator.SetBool("isLanding", false);
return;
}
bool playerHasVerticalSpeed = Math.Abs(playerRigidbody.velocity.y) > Mathf.Epsilon;
if (playerRigidbody.velocity.y >= 0)
{
playerAnimator.SetBool("isJumping", playerHasVerticalSpeed);
playerAnimator.SetBool("isLanding", false);
} else
{
playerAnimator.SetBool("isJumping", false);
playerAnimator.SetBool("isLanding", playerHasVerticalSpeed);
}
}
}
If my player went on slope, Animator shows my animations switch quickly between Run, Jump and Land. How to fix it to save correct jump animation?

Why the audio clip never heard when playing?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;
using Whilefun.FPEKit;
public class RoboSphereWindowBreakInteraction : MonoBehaviour
{
public Transform target;
public InteractableObjects interactableObjects;
public AudioClip audioClip;
public float speed;
private bool hasStarted = false;
private Animator anim;
void Update()
{
if ((Input.GetKeyDown(KeyCode.B) || (hasStarted == true)))
{
float step = speed * Time.deltaTime; // calculate distance to move
transform.position = Vector3.MoveTowards(transform.position, target.position, step);
hasStarted = true;
}
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject.name == "Square 1")
{
GetComponent<Rigidbody>().isKinematic = false;
hasStarted = false;
Destroy(GameObject.Find("Wall_Window_Long_03"));
}
}
public void ActivateRoboSphere()
{
foreach(Transform child in transform)
{
if(child.name == "Camera")
{
RepositionCamera(child);
}
}
anim = GetComponent<Animator>();
anim.enabled = true;
if (!anim.GetBool("Open_Anim"))
{
anim.SetBool("Open_Anim", true);
StartCoroutine(PlayAudio());
}
else
{
//anim.SetBool("Open_Anim", false);
}
}
private void RepositionCamera(Transform camera)
{
var Eyes = GameObject.Find("eyeDome");
camera.position = Eyes.transform.position + Eyes.transform.forward;
camera.LookAt(Eyes.transform);
camera.GetComponent<Camera>().enabled = true;
}
IEnumerator PlayAudio()
{
AudioSource audio = GetComponent<AudioSource>();
audio.Play();
yield return new WaitForSeconds(audio.clip.length);
audio.clip = audioClip;
audio.Play();
}
}
It's getting inside the PlayAudio but the sound is not heard.
The audio source component screenshot settings :

The only problem I see with this code is that initially, your audio source's clip isn't set to anything. Thus will result in a null ref exception on this line:
yield return new WaitForSeconds(audio.clip.length);
Add a null check and you should be good to go
if (audioSource.clip != null)
{
yield return new WaitForSeconds(audioSource.clip.length);
}

Player not moving to all waypoints.

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;
}

How can i access another script function if the script to access is not attached to the same gameobject?

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()
{
InstantiateObjects gos = GetComponent<InstantiateObjects>();
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.
