Hello guy. So i’m on start of part 7. I was making death function but my player doesn’t take dmg even though the take damage method I just added an if statement like in the video. Otherwise everything else i just copy and paste. When i got hit, the time is freeze which mean i got take dmg but for some reason the health is not minus like in the video

Record of test dmg function and errors And as the below video, you guyys could see that the game will be very slowly if I got hit by the moster and try to jump up. This is not happend before the death function is added. For the code, here is my player controller code

Here is the UI Manager script

<code>using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class UIManager : MonoBehaviour
{
    // Start is called before the first frame update
    public static UIManager Instance;

    [SerializeField] GameObject deathSceen;
    private void Awake()
    {
        if (Instance != null && Instance != this)
        {
            Destroy(gameObject);
        }
        else
        {
            Instance = this;
        }
        DontDestroyOnLoad(gameObject);
    }

    public SceneFading sceneFading;
    public void Start()
    {
        sceneFading = GetComponentInChildren<SceneFading>();
    }

    public IEnumerator ActiveDeathScreen()
    {
        yield return new WaitForSeconds(0.8f);
        StartCoroutine(sceneFading.Fade(SceneFading.fadeDirection.In));
        yield return new WaitForSeconds(0.9f);
        deathSceen.SetActive(true);
    }
}
</code>

The only path I change in the enemy script is here

<code>protected void OnCollisionStay2D(Collision2D _other)
{
    if (_other.gameObject.CompareTag("Player") && !Move.Instance.playerStateList.Invi && !Move.Instance.playerStateList.Invi && health > 0)
    {
        Attack();
        if (Move.Instance.playerStateList.alive)
        {
            Move.Instance.HitStopTime(0, 2, 0.5f);
        }

    }
}
</code>

Tks you guys.

Well firstly, your takedamage function has the wrong if statement it should be if (playerStateList.alive) but the one there now is if (!playerStateList.alive) Make this fix first, then see what still does not work

Ok it work but i found 2 other problem. The first error is happend with the input (again) that when i change the update to match with the video liek this

<code> private void Update()
 {
     if (playerStateList.incutscene) return;
     if (playerStateList.alive)
     {
         getInput();
     }
     UpdateJump();
     RestoreTimeScale();
     if (playerStateList.dashing || playerStateList.healing) return;
     FlashWhenInvi();
     if (playerStateList.alive)
     {
         Moving();
         Heal();
         CastSpell();
         Flip();
         Jump();
         StartDash();
         Attack();
     }
 }</code>

When i hold to heal, it stuck at the heal status but the heal doesn’t grow up. And you can’t moving or doing anything. Just stuck at healing forever without any health get. The Mana didn’t minus to heal the player. The second problem with the player is when player death but the enemy is to close, the player got push very far and there is 2 possibilities will happen. The first one is player got hit very far and the second is slowly go off. It’s kinda hard to explain but you can see in the record below. And the death scene doesn’t work perfectly. Sometime it just a black sceen and sometime it a death scene. Both of that is in the record i show you below

Death scene error record So how can i make my player stop at where it dead and make the death scene work perfectly everytime. tks you for helping me.

Heal() and cast() needs to be above the order of if(pState.healing) return , it should generally be like this

<code>    void Update()
    {
        if (playerStateList.incutscene) return;

        if(playerStateList.alive)
        {
            GetInputs();
        }
        UpdateJump();
        RestoreTimeScale();
        if (playerStateList.dashing) return;
        FlashWhileInvi();
        if (!playerStateList.alive) return;
        Move();
        Heal();
        CastSpell();
        if (playerStateList.healing) return;
        Flip();
        Jump();
        StartDash();
        Attack();
    }</code>

Tks. The heal work again but do you have any idea to fix the death scene? It got kinda random. Sometime it like the record I sent you before. Sometime it could look like this

And any idea to fix the player so he would stand still but not being floating when death?

Try to add rb.constraints = RigidbodyContraints2D.FreezePosition to your player death function for the gameover screen, ensure that the gameove text and button is below in the hiearchy of the scene fader, like this

Ok so it work to fix both the problem but then I figure out that the respawn just don’t work. I go to the altar and spam the f key alot but when i died and click respawn button. It just spawn me in the middle of the room and my character freeze

Respawn code

<code>public void respawnPlayer()
{
    if(alter != null)
    {
        if (alter.Interacted)
        {
            respawnpoint = alter.transform.position;
        }
        else
        {
            respawnpoint = platformRespawnpoint;
        }
    }
    else
    {
        respawnpoint = platformRespawnpoint;
    }
    Move.Instance.transform.position = respawnpoint;
    StartCoroutine(UIManager.Instance.DeactiveDeathScreen());
    Move.Instance.Respawn();
}</code>

Alter code

<code>private void OnTriggerStay2D(Collider2D _collision)
{
    if (_collision.CompareTag("Player") && Input.GetButtonDown("Interact"))
    {
        Interacted = true;
    }
}</code>

Respawn freeze video As you can see in the video. After get respawn i’m stuck and can’t move anywhere. Abd also sometime I respawn at the alter and sometime even if I interact with the alter. It still repsawn me in middle of the room like the img. but we could just skip the respawn point for now. How should I fix the free after respawn? thank you

Ok, i forgot to add that since the rb constraints are frozen when the player dies, you definitely need to remove the constraints when the player respawns

<code>            rb.constraints = RigidbodyConstraints2D.None;
            rb.constraints = RigidbodyConstraints2D.FreezeRotation;</code>

put this code in the respawnplayerfunction Also for the altar, put the code in the Update() function instead of the OnTriggerStay2D() function, i think it might help
