C# Creating a List of If Statements

Questions & Answers
1

Hi everyone, I want to put a list of if statements into a format similar to the way I have my buttons. But I’m not sure how. I would like to declare a bunch of them in a list but I don’t think you can make a list of if statements.

using UnityEngine;
using System.Collections;

public class SomeGUI : MonoBehaviour {
	
	public string[] someText;
	
	void OnGUI () {
	someText= new string[] {"Text1","Text2","Text3","Text4","Text5","Text6"};
		
for(int i = 0; i < someText.Length; i++){
//list of if statements
if(GUILayout.Button(someText*, GUILayout.Width(142), GUILayout.Height(25))){*

  •  	}*

}

  • }*
    }

You can use a switch statement:

switch(i) {
  case 0 : 
     // Do for 0
     break;
  case 1:
     // Do for 1 
     break;
  case 2:
     // Do for 2 
     break; 
  default:
     // Do for everything else
     break;
}

In that case I think you are looking for something like the following:

for (int i = 0; i < someText.Length; ++i) {
    if (GUILayout.Button(someText*, GUILayout.Width(142), GUILayout.Height(25))) {*

// If button was clicked change value of someInt (aka index of button).
someInt = i;
}
}

If you don’t mind getting a little fancy with .NET and C# you could do something like this:

using System;
using UnityEngine;
using System.Collections.Generic;

public class GUIScript : MonoBehaviour
{
	public class TextButton
	{
		public Rect Position;
		public string Text;
		public Action Action;
	}
	
	List<TextButton> _textButtons;
	
	// Use this for initialization
	void Start ()
	{
		_textButtons = new List<TextButton> ();

		_textButtons.Add (new TextButton { Position = new Rect (0, 0, 50, 50), Text = "text1", Action = () =>
		{
			// do whatever you would do when button 1 is hit
		}});
		
		_textButtons.Add (new TextButton { Position = new Rect (0, 75, 50, 50), Text = "text2", Action = () =>
		{
			// do whatever you would do when button 2 is hit
		}});
	}
	
	// Update is called once per frame
	void Update ()
	{
	
	}
	
	void OnGUI ()
	{
		foreach (TextButton textButton in _textButtons)
			if (GUI.Button (textButton.Position, textButton.Text))
				textButton.Action ();
	}
}
