Confused with using classes

Questions & Answers
1

This is probably a very basic question, but I wasn’t able to find a solution to my problem.
I have a C# script “Drawing” that has a function “DrawLine” that is called from OnGUI() to draw a line.

In my UnityScript script, I now just want to call this function from the script’s OnGUI(), but I don’t know how (this is my first time using classes).

Code Bits: (I’m only including the basic structure to save space):

Drawing.cs: (is not attached to any gameObject, just sits in the asset folder)

using System.Reflection;
using UnityEngine;
 
public static class Drawing
{
    public static void DrawLine(Vector2 pointA, Vector2 pointB, Color color, float width, bool antiAlias)
    {
         //here goes to actual line drawing code, etc.
    }
}

MainGUI.js:(attached to a gameObject)

function OnGUI()
{
     DrawLine(Vector2(100, 100), Vector2(150, 100), Color.white, 1, false);
}

So far I’, getting the error "Assets/Scripts/MainGUI.js(3,9): BCE0005: Unknown identifier: ‘DrawLine’.

I guess I have to create an instance somehow, but after some experimenting in js and c# I didn’t get anywhere :frowning:

Since your DrawLine function is static, you can call it without an instance. But you have to tell the compilter what class the function is in, so you call it like this…

Drawing.DrawLine(Vector2(100, 100), ...);

The problem is that in JS script you try to use class defined in C#. This basically won’t work, unless you put your C# class file into one of “first pass compilation folders”, described in point 1 of this help page.

EDIT: unless you really need to use two languages, please stick to only one in your project.
