Player invincibilty after colliding with an object.

Questions & Answers
1

Currently I’m working on a game where when you run into an object you will die and a death screen will pop up. There is an option to continue for 100 coins which when you press it you will be re spawned back to where you died and should have invincibly for 2 seconds to where you don’t collide with anything for that certain amount of given time. The re spawning of the character works but the player collides with the object instead of being able to have invincibility for 2 seconds. I don’t know what in my code is causing this, help would be appreciated.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class playerController : MonoBehaviour
{
    public GameManager theGM;

    public Rigidbody theRB;

    public float jumpForce;

    public Transform modelHolder;
    public LayerMask whatIsGround;
    public bool onGround;

    public Animator anim;

    private Vector3 startPosition;
    private Quaternion startRotation;

    public float invincibleTime;
    private float invincibleTimer;
    

    // Start is called before the first frame update
    void Start()
    {
        startPosition = transform.position;
        startRotation = transform.rotation;
     
    }

    // Update is called once per frame
    void Update()
    {
        if(theGM.canMove)
        {
            onGround = Physics.OverlapSphere(modelHolder.position, 0.2f, whatIsGround).Length > 0;

            if(onGround)
            {
                if (Input.GetMouseButtonDown(0))
                {
                    //Make the player jump
                    theRB.velocity = new Vector3(0f, jumpForce, 0f);
                }
            }
        }

        //control invincibility
        if(invincibleTimer > 0)
        {
            invincibleTimer -= Time.deltaTime
            
        }


        //control animations
        anim.SetBool("walking", theGM.canMove);
        anim.SetBool("onGround", onGround);
    }

    //checks for a collider with a trigger
    public void OnTriggerEnter(Collider other)
    {
        if(other.gameObject.tag == "Hazards")
        {
            if (invincibleTimer <= 0)
            { 
                Debug.Log("Hit Hazard");
                theGM.HitHazard();

                //theRB.isKinematic = false;

                theRB.constraints = RigidbodyConstraints.None;

                theRB.velocity = new Vector3(Random.Range(GameManager._worldSpeed / 2f, -GameManager._worldSpeed / 2f), 2.5f, -GameManager._worldSpeed / 2f);
            }
        }

        if(other.tag == "Coin")
        {
            theGM.AddCoin();
            Destroy(other.gameObject);
        }
    }

    public void ResetPlayer()
    {
        theRB.constraints = RigidbodyConstraints.FreezeRotation;
        transform.rotation = startRotation;
        transform.position = startPosition;

        invincibleTimer = invincibleTime;
    }

Hello.

I’m not sure but you are not doing anything to give “inveciblitty”. I see you do things when invencibl time is not 0, but you still have the collider on.

I think you should just add this:

void Update()
{
 if (invincibleTimer > 0)
 {
 gameObject.GetComponent<BoxCollider>()>.enabled=true;
 }
 else 
 {
  gameObject.GetComponent<BoxCollider>()>.enabled=false;
 }
}

This way, collider will be desactivated.

If this cause you problems like player needs to detect other colldiers. You shoud istead of desactiavting the player compoenet, desactivate the Hazards collider.

Colliders is who is detecting (not the rigidbody). So you should desaactivate them to prevent “collision or triggerIn”

Bye!
