Getting C# to access a javascript global Array and Components

Question

I'm trying to finally learn C# and am trying to get a script to access an global Java array.

The array has GameObjects in it and is in the plug-ins folder so it compiles first. And I'm trying basically to convert this java code to C# so I can use an Inventory System I've already made in Java Script with my GUI that I made in C#.

  tmpTexture = (GLOBALZ.objectsInWeapons[(4 * rows) + colmn].GetComponent(ObjectInfo).iconTexture);
  //set the object's texture

Basically all the game objects have a scripts attached called "ObjectInfo" that stores their icon.

I have no idea how to do this after 2 days of trying.

Thanks for any help.

It took you two days to figure this out? ... You might want to read this:

It should clear up a lot of confusion you might have.

As for your code, C# won't implicitly cast from Component to your own class, ObjectInfo. You need to explicitly cast it, and personally, my favorite way is with the as keyword. You also need to specify the type with GetComponent() (because GetComponent()'s parameter is a Type, so you need to use typeof()), although there are other ways of using GetComponent(), this is my favorite way).

tmpTexture = (GLOBALZ.objectsInWeapons[(4 * rows) + colmn].GetComponent(typeof(ObjectInfo)) as ObjectInfo).iconTexture;

Although that is an extraordinarily ugly line of code. I would make it neater:

GameObject tmpObject = GLOBALZ.objectsInWeapons[(4 * rows) + colmn]; ObjectInfo tmpInfo = tmpObject.GetComponent(typeof(ObjectInfo)) as ObjectInfo;

if(tmpInfo == null)
{
     // Couldn't retrieve the "ObjectInfo" script here.
}
else
{
     tmpTexture = tmpInfo.iconTexture;
}

See? Much, much easier to read and understand. :)
