Coroutines not working in Platformer game

Unity Engine
1

Hi, I’m sorry if this question has been asked already but I cant find any answers that apply to my specific scenario. I want to create a coroutine before I respawn the player in my game and also when the player gets hit (to not allow the player to move for a certain time) but for some reason my game completely ignores the coroutine and runs as if it wasn’t there. Note that I am running the coroutine in a singleton class. Also daze time is set to 0.3 in the referenced script. I am sort of new to coroutines… please help me if I am doing it wrong. Also, I don’t think respawn method is the problem but I posted it anyway, in case I am wrong.

using System.Collections.Generic;
using UnityEngine;

public class PlayerManager : MonoBehaviour {
   
    public static PlayerManager Instance {get; private set;}
    public CharacterController2D character;
    public int lives = 2;
    [HideInInspector]
    public bool isDead;
    [HideInInspector]
    public bool HandleInput = true;
    [SerializeField]
    private float _health = 100f;
    public float health
    {
        get
        {
            return _health;
        }

        set
        {
            if (value <= 0f) {
                _health = 0f;
            } else if (value >= 100f) {
                _health = 100f;
            } else {
                _health = value;
            }

        }
        else
        {
            Destroy (gameObject);
        }
    }

    {
        yield return new WaitForSeconds (character.animator.GetCurrentAnimatorClipInfo(0).Length);
        yield return new WaitForSeconds(3f);
    }

    public void Damage (float damage)
    {
        character.timer = 0;
        health -= damage * (1 / defense);
        character.animator.SetTrigger ("isHit");
        character.GetComponent<SpriteRenderer> ().color = new Color32 (249, 86, 86, 255);
        HandleInput = false;
        StartCoroutine (DamageCo());
        HandleInput = true;
        character.GetComponent<SpriteRenderer> ().color = new Color32 (255, 255, 255, 255);
    }
    private IEnumerator DamageCo()
    {
        yield return new WaitForSeconds (character.dazeTime);
    }


    public void Respwan (Transform[] checkpoint)
    {
        lives--;
        if (lives == 0)
        {
            character.transform.position = checkpoint [0].position;
            lives = 2;
            HandleInput = true;
            health = 100f;
        } else {
            for (int i = 0; i < checkpoint.Length; i++)
            {
                if (i == checkpoint.Length-1)
                {
                    character.transform.position = checkpoint [i].position;
                    HandleInput = true;
                    health = 100f;
                    return;
                }
                var distance = character.transform.position.x - checkpoint [i].transform.position.x;
                var toNextCheckpoint = character.transform.position.x - checkpoint [i+1].transform.position.x;

                if (distance >= 0 && toNextCheckpoint < 0) {
                    character.transform.position = checkpoint [i].position;

            }
        }
    }

A coroutine’s delays don’t affect the function that starts it. Only the coroutine itself is affected. With that in mind the following code is “starting” the coroutine (technically it’s just adding the function to a list of active coroutines), and then immediately continuing execution in the function it belongs to which means it’s immediately running the commands after the StartCoroutine() command which in this case means it’s immediately respawning.

public void Kill()
{
    HandleInput = false;
    character.animator.SetTrigger("die");
    StartCoroutine (KillCo());
    Respwan (LevelManager.Instance.checkpoints);
}

private IEnumerator KillCo()
{
    yield return new WaitForSeconds (character.animator.GetCurrentAnimatorClipInfo(0).Length);
    yield return new WaitForSeconds(3f);
}

If you want the respawn to occur after the delay, then you need to move the respawn function call to the coroutine itself.

public void Kill()
{
    HandleInput = false;
    character.animator.SetTrigger("die");
    StartCoroutine (KillCo());
}

private IEnumerator KillCo()
{
    yield return new WaitForSeconds (character.animator.GetCurrentAnimatorClipInfo(0).Length);
    yield return new WaitForSeconds(3f);
    Respwan (LevelManager.Instance.checkpoints);
}

I left the misspelling in place just in case you had purposefully spelled “Respawn” as “Respwan”.

Ohhh ok thanks you soo much!!! I was so confused about this!! Yes my spelling sucks.

Its working however, there’s another problem. After the player dies, I play the animation, but when the animation plays, it doesn’t fully complete because the player collides with the enemy and the enemy is blocking the player to fully complete the animation. As a result, the player glitches out when respawning. I tried Physics2d.ignorelayercollision() to no avail. Any idea how to fix this? Thanks in advance, help is much appreciated.
