I was wondering if it was possible to use arrays in a foreach loop? I have searched up a bit on it. But the only thing close to what I could find is an example from this webpage which uses an abstract array instead of a singular dimensional array, like the ones in the “myClass” class.
public class myClass {
public Gameobject[] pencils
public Gameobject[] rules;
public Gameobject[] erasers;
}
public class StationaryChooser : MonoBehaviour {
public string stationaryName;
public void OnGUI() {
foreach(Gameobject[] g in myClass) {
if (g.lenght > 0) {
for(int i = 0; i < g.lenght; i++) {
if (GUI.Button(new Rect(10 + (110 * i), 10, 100, 60), g[i].name)) {
stationaryName = g[i].name;
}
}
}
}
}
}
This example shown above is the basis of what I am trying to achieve.
Any help would be thankful 
Basically you want to iterate over an object or static class, it is a bit tricky to do.
You could create a method to get all objects, I used List<>, but you can change to Array.
I have not tested the code, but you might get the idea.
public class myClass
{
public Gameobject[] pencils;
public Gameobject[] rules;
public Gameobject[] erasers;
public List<Gameobject[]> GetObjects()
{
var objects = new List<Gameobject[]>();
objects.Add(pencils);
objects.Add(rules);
objects.Add(erasers);
return objects;
}
}
public class StationaryChooser : MonoBehaviour
{
public string stationaryName;
public void OnGUI() {
foreach(var g in myClass.GetObjects())
{
foreach(var obj in g)
{
if (GUI.Button(new Rect(10 + (110 * i), 10, 100, 60), obj .name))
{
stationaryName = obj .name;
}
}
}
}
}
@maikonfarias Sorry for the late reply, But I cant seem to understand how this works? 
.
I have searched the internet for a while now, and have not come up with any results concerning this.
Your example looks functional in a workings of it, but I don’t know how to implement it into my current script unfortunately, it also throws up quite a few errors.
@djfunkey, in the example you can gave, you think that you can access the public fields in your ‘myClass’ class by their type, this is by your usage of the foreach loop:
...
foreach(Gameobject[] g in myClass) {
if (g.lenght > 0) {
for(int i = 0; i < g.lenght; i++) {
if (GUI.Button(new Rect(10 + (110 * i), 10, 100, 60), g[i].name)) {
stationaryName = g[i].name;
}
}
}
}
...
This is incorrect with the exception of using reflection to go over the properties. The example maikonfarias gave included a convenience method to add your public properties (pencils, rules, erasers) to a List of GameObject[ ] through a new method in the ‘myClass’ class called GetObjects. If that method is called in the form maikonfarias wrote it, it would return a List with three elements/items/thingers in it, index 0 would be the pencils GameObject array, index 1 would be the rules GameObject array and finally the last, index 2 would be erasers GameObject Array.
@Landern: Good explanation.
The method GetObjects() is like a shortcut to your objects.
For my code to work I need more context what it is about, for example, the class myClass and its methods/members should be static, or you would need a object to access myClass.
public static class myClass
{
public static Gameobject[] pencils;
public static Gameobject[] rules;
public static Gameobject[] erasers;
public static List<Gameobject[]> GetObjects()
{
var objects = new List<Gameobject[]>();
objects.Add(myClass.pencils);
objects.Add(myClass.rules);
objects.Add(myClass.erasers);
return objects;
}
}
or
public class StationaryChooser : MonoBehaviour
{
public string stationaryName;
// get myClass object access if it is in the same object
var objectMyClass = this.gameObject.GetComponent<myClass>();
public void OnGUI() {
foreach(var g in objectMyClass.GetObjects())
{
foreach(var obj in g)
{
if (GUI.Button(new Rect(10 + (110 * i), 10, 100, 60), obj.name))
{
stationaryName = obj.name;
}
}
}
}
}
@maikonfarias Thank you a lot!! You helped so much. I finally figured out my problem…
I only had:
using UnityEngine;
using System;
Which was making every List collection through up an error. A silly mistake on my part sorry!
using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;
public class myClass {
public Gameobject[] pencils;
public Gameobject[] rules;
public Gameobject[] erasers;
public List<Gameobject[]> GetObjects()
{
var objects = new List<Gameobject[]>();
objects.Add(pencils);
objects.Add(rules);
objects.Add(erasers);
return objects;
}
}
public class StationaryChooser : MonoBehaviour {
private myClass mClass;
public string stationaryName;
void Awake() {
mClass = GetComponent<myClass>();
}
public void OnGUI() {
foreach(var g in myClass.GetObjects) {
if (g.lenght > 0) {
for(int i = 0; i < g.lenght; i++) {
if (GUI.Button(new Rect(10 + (110 * i), 10, 100, 60), g[i].name)) {
stationaryName = g[i].name;
}
}
}
}
}
}
@maikonfarias I have run into a problem with my Script and I am trying to convert it from List<> to Array, But I am unsure how to convert it. You also mentioned I should do this in your original post.
I have tried using ArraySegment, Array, and ArrayList, In different places within the script, but they are fairly new to me and I don’t think I am implementing them right. Could you please provide some assistance.
