Help with coding

Unity Engine
1

So i was trying to add bullets into my game and i made a code
and i dont know what to do to fix this code
var Bullet : GameObject;
var Spawn : Transform;

function Update ()
{
if(Input.GetButtonDown[‘fire1’)){
fire[ ];
}
}

function fire()(
instancelate(Bullet.Spawn.Position.Spawn.Rotation);
}
This is For the m4 and i am going to implement a ak47

If your coding for a gun you probably want it to use raycast and not a bullet object.
I’ll give you a basic(but working) unityscript that I use. It’s for one shot weapons since you didn’t say what
type of weapon you want. May not be the best but it works.

var shotSound : AudioClip; // Shot sound
var bloodPrefab : GameObject; // Blood for enemy
var sparksPrefab: GameObject; // Sparks for groun
var muzzleFlash : GameObject;
var shootEnabled: boolean = true; // allows disabling the shots
var ChangeWep : boolean = true;
var RayCastDist : float = 50;

var Bullets = 9;
var MaxBullets = 9;
var Clip = 9000;
var force = 50;
var Recoil = 10;
var Accuracy = 50;
var shotInterval = 1.0;
var Cost = 50;
var Zoom : int;

function Start(){
    Zoom = (PlayerPrefs.GetInt("FOV") - 5);
    muzzleFlash.renderer.enabled = false;
    shootEnabled = true; // allows disabling the shots
    ChangeWep = true; 
}

function Update(){
    var forward : Vector3 = transform.TransformDirection(Vector3.forward) * 10;
    
    if (Input.GetButtonDown("Fire1")){
        if (shootEnabled == true){
            if (Bullets > 0){
                if (Clip > 0){
                    Shoot();
                    Bullets -= 1;
          }
       }
    }
  }
  
  if (Input.GetButtonUp("Fire1")){
      ChangeWep = true;
  }
    
    if (Bullets == 0){
        if (Clip >= 1){
            Clip -= 1;
            Bullets = MaxBullets;
        }
        if (Clip == 0){
            Bullets = 0;
        }
    }
}

function Shoot(){
    var cam : Transform = Camera.main.transform;
    var ray = new Ray(cam.position, cam.forward);
    var hit : RaycastHit;
    var trf = transform; // a little optimization
    var hitRotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
    
    audio.PlayOneShot(shotSound); // play the shot sound...
    MuzzleFlashOn();
    
        if(Physics.Raycast (ray, hit, RayCastDist)){
        var rot = Quaternion.FromToRotation(Vector3.up, hit.normal);
                 
            if(hit.collider.gameObject.tag == "Box"){
                Debug.Log ("Hit A Box!");
                if (sparksPrefab) Instantiate(sparksPrefab, hit.point, rot); 
                hit.rigidbody.AddForceAtPosition(force * transform.forward , hit.point);
                hit.collider.SendMessageUpwards("ApplyDamage", 5.0);

        }
            if(hit.collider.gameObject.tag == "Enemy"){
                Debug.Log ("Hit A Enemy!");
                hit.collider.gameObject.BroadcastMessage("LoseHealth", force * 2 / 4);
                if (sparksPrefab) Instantiate(sparksPrefab, hit.point, rot);
                
        } 
            if(hit.collider.gameObject.tag == "Target"){
                Debug.Log ("Target hit!");
                hit.rigidbody.AddForceAtPosition(force * transform.forward , hit.point);
                hit.rigidbody.isKinematic = false;
                hit.rigidbody.useGravity = true;
                if (sparksPrefab) Instantiate(sparksPrefab, hit.point, rot); 
            
            } else {            
            if (sparksPrefab) Instantiate(sparksPrefab, hit.point, rot);
            Debug.Log ("Hit Other!");
            
        }
        ChangeWep = false;
        SendMessageUpwards("Recoil");
        shootEnabled = false;
        yield WaitForSeconds(shotInterval);
        shootEnabled = true;
        ChangeWep = true;    
        }
    }  

function MuzzleFlashOn()
{
    var muzzleFlashLength = 0.1;
    muzzleFlash.renderer.enabled = true;
    yield WaitForSeconds(muzzleFlashLength);
    muzzleFlash.renderer.enabled = false;
}

When i try to compile it I got Unknown identifier on the OnGUI(); part line 107

4

OnGUI isn’t part of the script chrisall76 gave you - your error lies elsewhere in another file?

Double click on errors in the console, it’ll point you to the line in question in monodevelop.

I fixed the error for him, I forgot to get rid of a OnGui(); somewhere in there. Fixed it now.

6

i contacted him and he fixed the OnGui

7

The script doesn’t seem to need this line or the zoom var.

Zoom = (PlayerPrefs.GetInt(“FOV”) - 5);

I got rid of somethings, that was part of my code for the start of aim down sights.
