Revise your PlayerController script to make PickUpGameObjects disappear when they collide with the Player sphere

Tag PickUp GameObjects and write conditional statements to make sure they’re the only things that disappear

Set the Prefab PickUp Collider as a trigger and add a Rigidbody component, to make the collectibles work properly

Unit 2 - Program a basic game

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

public class PlayerController : MonoBehaviour
{
    public float speed = 0;

    private Rigidbody rb;

    private float movementX;
    private float movementY;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    private void OnMove(InputValue movementValue)
    {
        Vector2 movementVector = movementValue.Get<Vector2>();

        movementX = movementVector.x;
        movementY = movementVector.y;
    }

    private void FixedUpdate()
    {
        Vector3 movement = new Vector3(movementX, 0.0f, movementY);

        rb.AddForce(movement * speed);
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("PickUp")) 
        {
            other.gameObject.SetActive(false);
        }
    }
}

Detecting Collisions with Collectibles

1. Disable PickUps with OnTriggerEnter

2. Add a tag to the PickUp Prefab

3. Write a conditional statement

4. Set the Pickup Colliders as triggers

5. Add a Rigidbody component to the PickUp Prefab
