projectile.velocity error.

I found this script in C but it doesn't work and I was unable to debug. Can anyone correct my mistakes please, thank you very much.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Shooting : MonoBehaviour {
5.  
6. public Rigidbody bulletPrefab;
7.       public float shootSpeed = 300;
8.      
9.       private bool playerInRange = false;
10.       private float lastAttackTime = 0f;
11.       private float fireRate = 0.5f; //how many bullets are fired/second
12.       private Transform player = null;
13.      
14.       void OnTriggerEnter(Collider other)
15.       {
16.           if(other.tag == "enemy")
17.           {
18.               playerInRange = true;
19.               player = other.transform;
20.           }
21.       }
22.      
23.       void OnTriggerExit(Collider other)
24.       {
25.           if(other.tag == "enemy")
26.           {
27.               playerInRange = false;
28.               player = null;
29.           }
30.       }
31.      
32.       void Update()
33.       {
34.           if (playerInRange)
35.           {
36.               //Rotate the enemy towards the player
37.               transform.rotation = Quaternion.LookRotation(player.position - transform.position, transform.up);
38.              
39.               if (Time.time - lastAttackTime >= 1f/fireRate)
40.               {
41.                   shootBullet();
42.                   lastAttackTime = Time.time;
43.               }
44.           }
45.       }
46.      
47.       void shootBullet()
48.       {
49.        
50.           var projectile = Instantiate(bulletPrefab, transform.position, transform.rotation);
51.           //Shoot the Bullet in the forward direction of the player
52.           projectile.velocity = transform.forward * shootSpeed;
53.     }
54. }

 

In a word: no. You haven't said what doesn't work. Does it compile? Do the trigger enter and exit functions get called? Does playerInRange ever get set true? Does the bullet shoot? Does it go in the right direction?

Assuming it compiles, add in lots of debug logging to see what does and doesn't work.

 

Your problem is with the instantiate line at the bottom, https://docs.unity3d.com/ScriptReference/Object.Instantiate.html

Unless you know what your doing never just copy & paste code. You wont learn anything & if it breaks you will have no idea how to fix it since you dont know how it works. Its good practice to write it out yourself compile as you go & deal with the errors as they crop up.
