What's wrong with this code ?

Im new here and speak a little english, sorry for some error
I need some help with this code, somethings wrong

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class AK47AI : MonoBehaviour {
5.  
6.     public ParticleSystem Particula;
7.  
8.     // Use this for initialization
9.     void Start () {
10.         Particula.enableEmission = false;
11.    
12.     }
13.    
14.     // Update is called once per frame
15.     void Update () {
16.         if (Input.GetKey (KeyCode.Mouse0))  (
17.                   Particula.enableEmission = true; )
18.          else (
19.                   Particula.enableEmission = false;
20.         )
21.  
22.    
23.     }
24. }
25.  

 

Your if else statement is surrounded by () where it should be {}

 

could you leave an exemple?

 

Code (CSharp):

1.  void Update ()
2. {
3.         if (Input.GetKey (KeyCode.Mouse0))
4.         {
5.                   Particula.enableEmission = true;
6.          }
7.          else
8.           {
9.                   Particula.enableEmission = false;
10.            }  
11. }

 

VERY THANKS !
