I just started coding so i still have so much to learn. Unity doesn't give any error when I play the game but also nothing happenes when the player touches the gold. I want the gold to dissapear when the playes touches it but I don't know why it doesn't work. (collision part is the last part)

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

public class Player : MonoBehaviour
{

    private Rigidbody2D myRigidbody;
    private Animator anim;

    [SerializeField]
    private int speed;
    private bool lookright;


     void Start()
    {
        myRigidbody = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();
        
        lookright = true;
    }

    
    void Update()
    {

        float horizontal = Input.GetAxis("Horizontal");
        movements(horizontal);
        changedirection(horizontal);

    }
    private void movements (float horizontal)
    {
        anim.SetFloat ("Walk", Mathf.Abs(horizontal));
        myRigidbody.velocity = new Vector2 (horizontal*speed, myRigidbody.velocity.y);

    }
    private void changedirection(float horizontal)
    {

        if (horizontal > 0 && !lookright || horizontal < 0 && lookright)
        {
            lookright = !lookright;
            Vector3 direction = transform.localScale;
            direction.x *= -1;
            transform.localScale = direction;
        }

    }

    void OnCollisionEnter2D(Collision2D other)
    {

        if (other.gameObject.tag == "gold")
        {
            other.gameObject.SetActive(false);
        }
        
    } }

This is the Unity inspector of the gold

CodePudding user response：

OnCollisionEnter2D(Collision collision) won't fire when you have its IsTrigger set to true. Change it to OnTriggerEnter2D(Collider2D collider) and it will work.

Take a look at the documentation for colliders.
