Compilation error when calling a C# from a Unityscript (js) in Unity3d

Hello to all. I need a little help to make a call of a C# through a js script in Unity3d. The script I'd like to call is named "IsometricBheaviour.cs" and it is placed in Asset/Plugins folder.

This is the coding of the "IsometricBheaviour.cs" script:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class IsometricBheaviour : MonoBehaviour {
6.  
7.     private static bool mIsRotated = false;
8.     private static bool mMustRotate = false;
9.     private GameObject whatever;    
10.        
11.     // Use this for initialization
12.     void Start ()
13.     {
14.         whatever = GameObject.Find ("MarkerObject");
15.     }
16.      
17.     // Update is called once per frame
18.     void Update ()
19.     {
20.     // Update is called once per frame
21.     }
22.         void Isometric ()
23.         {
24.         if (mMustRotate  !mIsRotated)
25.         {
26.             //Rotate all models 45 degrees around X
27.             if (whatever != null) {
28.                 GameObject modelUnderChipsTrackable = whatever.transform.GetChild(0).gameObject;
29.                 modelUnderChipsTrackable.transform.RotateAround(new Vector3(1,0,0), Mathf.PI/3);
30.                  
31.                 }
32.             mIsRotated = true;
33.             mMustRotate = false;
34.        
35.  
36.             {
37.               if (!mIsRotated)
38.                 {
39.                 mMustRotate = true;
40.                 }
41.     }
42. }
43.     }
44. }
45.  

The javascript that I want to use to call the "IsometricBheaviour.cs" script is basically a GUI controller script, with some buttons.
Here is the coding for calling the C# script:

Code (csharp):

1.  
2. #pragma strict
3.     var native_width :  float = 480;
4.     var native_height : float = 320;
5.     var ctrlImage : Texture2D;
6.     var txtImage : Texture2D;
7.     var btnTexture1 : Texture;
8.     var btnTexture2 : ........... ;
9.     var btnTexture3 : ........... ;
10.  
11.  
12.     function Start() {
13.    }
14.    
15.     function Update() {
16.     }
17.    
18.  
19.     function OnGUI ()
20.     {
21.         //set up scaling
22.         var rx : float = Screen.width / native_width;
23.         var ry : float = Screen.height / native_height;
24.      
25.         GUI.matrix = Matrix4x4.TRS (Vector3(0, 0, 0), Quaternion.identity, Vector3 (rx, ry, 1));
26.      
27.         //now create your GUI normally, as if you were in your native resolution
28.         //The GUI.matrix will scale everything automatically.
29.      
30.         GUI.Box( Rect(10, 100, 420, 120) ,ctrlImage, "");
31.      
32.         if (!btnTexture1)
33.             {
34.             Debug.LogError("Please assign a texture on the inspector");
35.             return;
36.             }
37.      
38.         if(GUI.Button(Rect(40, 134 50, 30), btnTexture1));
39.           var runScript1 : GameObject[] = GameObject.FindGameObjectsWithTag("markerObject");    
40.             for(var doIsometric : GameObject in runScript1)
41.                {    
42.              var script1 : IsometricBheaviour = doIsometric.GetComponent(IsometricBheaviour);    
43.              if(script1)
44.              {
45.               IsometricBheaviour.doIsometric();
46.              }    
47.             }  
48.  
49.  

I cannot make it compile. I get the following error:

" Error BCE0018: The name 'IsometricBheaviour' does not denote a valid type ('not found'). Did you mean 'System.Net.Sockets.IOControlCode'? (BCE001 (Assembly-UnityScript-firstpass)"


Can someone help me, make this javascript work? I am new to Unity and programming and I got stuck on this big time now.
I have placed the C# in plugins folder as mentioned here

Still I get no compilation. Thank you all for your time, reading this post. Any advice, is very much welcomed.

 

Hello @Graham Dunnett. Thanks for your time reading my question. I've made a typo in my post. The folder is indeed named Plugins. I will edit the post asap. Though the folder name is correct, do you think there is something wrong with the coding, and I get such an error on compilation?

 

Thank you @Graham Dunnett for your time and efford fixing those errors in code. Because I am a noob to programming and Unity, could you explain in detail how should I use the "Library/ScriptAssemblies, with the csharp ending up in Assembly-CSharp-firstpass.dll", that you mentioned in your answer?

I understand that compliler, is looking for the C# script, cause it couldn't find it, right? The script is at Assets/Plugins folder, so what should I fix to the coding to make it compile and how should I call the "IsometricBheaviour.cs" C# script, through the js?
