Custom Inspector Internal Compiler Error

Unity Engine
1

This is my first time making a Custom Inspector and it’s giving me an “Internal Compiler Error” with a basically empty Editor file. It’s placed in the Assets/Editor folder:

using UnityEngine;
using UnityEditor;
using System.Collections;

[CustomEditor(typeof(generator))]

public class GenEditor : Editor {


	public override void OnInspectorGUI() {

		generator myTarget = (generator) target;


	}

}

Is it something to do with the script it’s referencing or some kind of link I haven’t set up in Unity? Here’s the debug log:

One Bump, this is really giving me a hard time, I know I’m missing something…

3

Last Bump, please help! Anything you know might help.

4

If you post a dropbox download containing a minimal example project which exhibits this issue, I would be happy to take a quick look for you.

5

Well, it’s happening on everything. It’s not specific to any script. It seems the set up code I posted above or some dynamic link has gone awry. So the set-up code above is all I can really give you…

6

I apparently was missing some of the error log

7

Without a simple project which reproduces the problem I am not going to be able to help.

8

Can you post the script that this Custom Editor is for? Looking at both would be helpful.

9 
using UnityEngine;
using UnityEditor;
using System.Collections;

public class generator : MonoBehaviour {
public int x = 0;

void Start(){
 DoSomething();
}

DoSomething() {
x = 1;
}
}

There’s no common occurrences of internal compiler errors when setting up custom editors?

10

So just looking at you script the issue I see is that you’re calling

generator myTarget = (generator) target;

but “generator” is never declared.

Also you’re calling CustomEditor(typeof(generator)). Is the class you’re trying to edit called generator with a little g?

edit:
NM, read that wrong. Lemme copy those down and I’ll check them out.

This script, plus that editorscript in assets/editor gives me an internal compiler error, and any other script I could create that I reference gives me the same thing. It doesn’t seem as if the script matters at all.

It’s giving me .x in my autocomplete list when I go to reference myTarget. So it seems as if it’s linking correctly in Monodevelop. Yes, the names are correct, is there a way I should be “declaring” a script in the beginning of my editor? Like I said I’m new to Custom Editors, as far as I know “generator” doesn’t need to be declared, as it’s referencing an existing script, not a variable.

12

The only thing which springs to my mind with this limited information is that your script name differs from your class name… I have known this to cause issues in the past. Your script files should be named “Assets/generator.cs” and “Assets/Editor/GenEditor.cs”.

13

I moved the file out of the editor file just to see what the debug log, and it mentions ensuring that the script being referenced is derived from a scriptableobject, could this be the problem? I’m not entirely sure how to go about that but I’m gonna look now while I wait for answers :stuck_out_tongue:

Well usually you want to cache a reference to it for later on like so:

using UnityEngine;
using UnityEditor;
using System.Collections;

[CustomEditor(typeof(generator))]
public class GenEditor : Editor {
    generator myTarget;

    void OnEnable () {
        myTarget = (generator)target;
    }
    
    public override void OnInspectorGUI() {
        generator myTarget = (generator) target;
    }
    
}

It worked fine for me with one minor change, your DoSomething wasn’t set up as a method:

using UnityEngine;
using UnityEditor;
using System.Collections;

public class generator : MonoBehaviour {
    int x = 0;
    
    void Start(){
        DoSomething();
    }
    
    void DoSomething() {
        x = 1;
    }
}

With that change it worked fine for me.

15

It’s definitely not the names, I double,triple,quadruple check them and then some.

16

Wait, is the generator file in an Editor folder? It shouldn’t be, only the GenEditor file should go in an Editor folder.

17

Ah, I missed that with that particular script example, but changing it didn’t fix it for me, which confirms what I thought, there’s something wrong with my Unity-Monodevelop dynamic linking. Thanks for the help guys.

This is driving me nuts… So now it seems that any script I place in Assets/Editor is giving me an internal compiler error. Is there anyone who knows why this would happen? I’m talking any script… Js,boo,c#, any contents, any derivation. If it’s a script I get an Internal Compiler Error…
