Help with Script,converting Java to C#

// Can anyone please tell me how do I write this in c# ...thanks a lot


public void FireProjectile()
{

var newMissile = Instantiate(myProjectile, muzzlePositions.position, muzzlePositions.rotation);
newMissile.GetComponent(Projectile_Missile).myTarget = myTarget;
}

 

It's hard to see what your classes consists of, but that code will compile in C#, newMissile is just typed implicitly.

If you're having errors post them

edit: you might need to change this line:

Code (csharp):

1. newMissile.GetComponent(Projectile_Missile).myTarget = myTarget;

to

Code (csharp):

1. newMissile.GetComponent("Project_Missile").myTarget = myTarget;

or

Code (csharp):

1. newMissile.GetComponent<Project_Missile>().myTarget = myTarget;

 

thank you for your reply it is a script for a turret that shot missile ....

with your first suggestion I get this error

error CS1061: Type `UnityEngine.Object' does not contain a definition for `GetComponent' and no extension method `GetComponent' of type `UnityEngine.Object' could be found (are you missing a using directive or an assembly reference?)

 

2nd suggestion gives me this error

error CS0201: Only assignment, call, increment, decrement, and new object expressions can be used as a statement

 

This is original script of turret in js (tower defence) , I am trying to change it into c# but those 2 lines above are giving me lots of problems ... thanks for any help in advance

Code (JavaScript):

Change var newMissile to GameObject newMissile on line 81

Line 82 (assuming Projectile_Missile is a valid type) try newMissile.GetComponent<Projectile_Missile>().myTarget = myTarget

 

Projectile_Missile is the name of the script we are trying to get component from ... but sadly this does not work still getting an error in this line of code ... thanks though

error CS1061: Type `UnityEngine.Object' does not contain a definition for `GetComponent' and no extension method

I remember in the past doing first something like this when I wanted to get a component from a script on another object

void Start ()
{
EnemyArray = Object.FindObjectsOfType (typeof (Projectile_Missile)) as projectile_Missile[];
}

but the thing is that I cant see anything like it in original js ... is it possible it is because js does not need to do that? I have no knowledge of js so find it hard to convert

 

Code (csharp):

1.  
2. var newMissile = Instantiate(...) as GameObject;
3. newMissile.GetComponent<Projectile_Missile>().myTarget = myTarget;
4.  

 

That's is working ... thank you so much ... great to learn something new

I actually got it working this way by adding this to projectile script , but it was less efficient ;

Code (CSharp):

1. public Player player;
2.  
3.  
4. public void Awake ()
5.     {
6.         GameObject playerObject = GameObject.FindWithTag ("Player") ;
7.         if ( playerObject !=null)
8.         {
9.             player = playerObject.GetComponent<Player>();
10.         }
11.     }
12.  
13.  
14. public void Update ()
15.     {  
16.  
17.         myTarget = player.myTarget;
18.                                  }
19.
