I attempted to create a system whereby collecting an item increases the player’s fire rate using the following pairs of scripts:
using UnityEngine;
using System.Collections;
public class ShootSpeedConsumeByContact : MonoBehaviour
{
public GameObject absorb;
public float spdValue;
private GameController playerController;
void Start()
{
GameObject playerControllerObject = GameObject.FindWithTag("Player");
if (playerControllerObject != null)
{
playerController = playerControllerObject.GetComponent<GameController>();
}
if (playerControllerObject == null)
Debug.Log("Cannot find 'PlayerController' script");
}
void OnTriggerEnter(Collider other)
{
if (other.tag == "Boundary")
{
return;
}
if (other.tag == "Player" || other.tag == "Shield")
{
Instantiate(absorb, transform.position, transform.rotation);
playerController.AddShootSpd(spdValue);
Destroy(gameObject);
}
if (other.tag == "Projectile")
{
Instantiate(absorb, transform.position, transform.rotation);
Destroy(other.gameObject);
Destroy(gameObject);
}
}
}
and
using UnityEngine;
using System.Collections;
[System.Serializable]
public class Boundary
{
public float xMin, xMax, zMin, zMax;
}
public class PlayerController : MonoBehaviour
{
public float spread;
public float speed;
public float tilt;
public Boundary boundary;
private Rigidbody rb;
public GameObject shot;
public Transform shotSpawn;
public float fireRate;
private float nextFire;
private AudioSource audioSource;
void Start()
{
rb = GetComponent<Rigidbody>();
audioSource = GetComponent<AudioSource>();
}
void Update ()
{
if (Input.GetButton("Fire1") && Time.time > nextFire)
{
nextFire = Time.time + fireRate;
Instantiate(shot, new Vector3 (shotSpawn.position.x-spread,shotSpawn.position.y,shotSpawn.position.z), shotSpawn.rotation);
audioSource.Play();
spread = spread * -1;
}
}
void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
rb.velocity = movement * speed;
rb.position = new Vector3
(
Mathf.Clamp(rb.position.x, boundary.xMin, boundary.xMax),
0.0f,
Mathf.Clamp(rb.position.z, boundary.zMin, boundary.zMax)
);
rb.rotation = Quaternion.Euler(0.0f, 0.0f, rb.velocity.x * -tilt);
}
public void AddShootSpd(float newShootSpdValue)
{
fireRate += newShootSpdValue;
}
}
It wasn’t working and I wanted to show my friend how the game worked, so I turned off the pickup item’s script and the game ran fine. I turned the object back on and tried to fix the code, and suddenly all my scripts ceased functioning. I tried restarting Unity and this did not work, I tried reverting the scripts to what you see above and the game still would not run. I checked an unrelated script, and suddenly all my instances of Random.Range are underlined in red:

Visual Studio suggests I convert them to either System.Random.Range or UnityEngine.Random.Range. What do I do? How do I get my scripts to compile again? Which Random Range is the right one?
