How do i create a gameobject, add a script to it, and change a public variable on that script. all from js

Question

Here is my JS:

 #pragma strict
 
 function Start () {
     var testobj : GameObject;        
     testobj = new GameObject ("test");
     testobj.AddComponent ("OBJ");
     var targetComp : script = testobj.GetComponent(OBJ);
     OBJ.objPath = "http://www.everyday3d.com/unity3d/obj/monkey.obj" ;
 }
 
 function Update () {
 
 }

I get an error about the code before i can run it stating:

Assets/OBJ/src/createobj.js(7,26): BCE0018: The name 'script' does not denote a valid type ('not found'). Did you mean 'UnityEditor.ScriptCallOptimizationLevel'?

this is a unity3d webplayer app

Any help would be great ty

Assuming 'OBJ' is the name of the script you are trying to add and that 'objPath' is not static, you can do it this way:

 #pragma strict
  
 function Start () {
     var testobj : GameObject;   
     testobj = new GameObject ("test");
     testobj.AddComponent (OBJ);
     var targetComp : OBJ = testobj.GetComponent(OBJ);
     targetComp.objPath = "http://www.everyday3d.com/unity3d/obj/monkey.obj" ;
 }

TY for your quick response. yes your assumptions are correct. However with these changes i get an error stating:

Assets/OBJ/src/createobj.js(7,22): BCE0018: The name 'OBJ' does not denote a valid type ('not found').

And the script im trying to add is OBJ.cs what does the "Bug19" do in this example?

Line 6 seems to have gone funny! I'm assu$$anonymous$$g it was UA auto-formatting of some kind.

 // testobj.AddComponent (Bug19);
 testobj.AddComponent (OBJ);

Surely there could be a better name for the script than OBJ zer0c?

Im still getting the error :Assets/OBJ/src/createobj.js(7,22): BCE0018: The name 'OBJ' does not denote a valid type ('not found'). its like its looking for the script that wont be added till runtime.. the script is located under assets:OBJ:src folder

So it seems you are using both C# and uJS. This is going to lead to headaches, you are better off just working in one language. The problem is the Script Compilation Order. Check my answer here on how to use both languages in the same project : http://answers.unity3d.com/questions/385582/how-to-connect-2-scripts-using-c-js.html

And be wary of the point about when you do this, only one language will be able to see the other e.g. uJS can see C#, but C# cannot see uJS.

Edit : all the Unity Documentation links have changed, here is the link : http://docs.unity3d.com/Documentation/$$anonymous$$anual/ScriptCompileOrderFolders.html

I ran a quick test on the code before I posted it. Since I did not have an 'OBJ' script, I put in a script I did have ('Bug19') and I missed changing one back when I changed them back for posting.

As for fixing the 'valid type' problem, on the few occasions I've mixed languages, I tossed the C# in StandardAssets as indicated in the link @alucardj provided.
