Hello Terence! I’ve got an issue. Could you help me to resolve it?

When I trying to compilate the game I getting an errors

Assets\Scripts\Weapons\WeaponDataEditor.cs(8,33): error CS0246: The type or namespace name ‘Editor’ could not be found (are you missing a using directive or an assembly reference?)

Assets\Scripts\Weapons\WeaponDataEditor.cs(6,2): error CS0246: The type or namespace name ‘CustomEditorAttribute’ could not be found (are you missing a using directive or an assembly reference?)

Assets\Scripts\Weapons\WeaponDataEditor.cs(6,2): error CS0246: The type or namespace name ‘CustomEditor’ could not be found (are you missing a using directive or an assembly reference?)

using UnityEditor;
using System;
using System.Linq;
using System.Collections.Generic;

[CustomEditor(typeof(WeaponData))]

public class WeaponDataEditor : Editor
{

WeaponData weaponData;
string[] weaponSubtypes;
int selectedWeaponSubtype;

void OnEnable()
{
// Cache the weapon data value
weaponData = (WeaponData)target;

//Retrive all the weapon subtypes and cache it
System.Type baseType = typeof(Weapon);
List<System.Type> subTypes = System.AppDomain.CurrentDomain.GetAssemblies()
.SelectMany(s => s.GetTypes())
.Where(p => baseType.IsAssignableFrom(p) && p != baseType)
.ToList();

//Add a none option on front
List<string> subTypesString = subTypes.Select(t => t.Name).ToList();
subTypesString.Insert(0, "None");
weaponSubtypes = subTypesString.ToArray();

//Ensure that we are using the correct weapon subtype
selectedWeaponSubtype = Math.Max(0, Array.IndexOf(weaponSubtypes, weaponData.behaviour));
}

public override void OnInspectorGUI()
{
//Draw a dropdown in the Inspector
selectedWeaponSubtype = EditorGUILayout.Popup("Behaviour", Math.Max(0, selectedWeaponSubtype), weaponSubtypes);

if (selectedWeaponSubtype > 0)
{
//Updates the behaviour field
weaponData.behaviour = weaponSubtypes[selectedWeaponSubtype].ToString();
EditorUtility.SetDirty(weaponData); //Marks the object to save
DrawDefaultInspector(); //Draw the default inspector elements
}
}
}

Hello, ZBeast!

It looks like you are encountering errors related to namespaces and types when trying to compile your game. The errors specifically mention that the ‘Editor’ type, ‘CustomEditorAttribute’ type, and ‘CustomEditor’ type could not be found.

Here are some steps you can take to resolve the issues:

1. Add the following using directive at the

@zbeast you need to put your editor scripts inside a folder named Editor (anywhere in your project). Otherwise, they will be compiled, and the UnityEditor namespace is not included in your build.
