C# GUI.Tooltip If Statement

Questions & Answers
1

Hey everyone, is there a way to put an if statement inside of a GUI.Tooltip? I want an if statement to check if a variable is null and if it is don’t display it in the GUI.Tooltip. I’m not sure if I want to put the if statement inside of the GUI.Button or above the GUI.Label.

using UnityEngine;
using System.Collections;
 
public class example : MonoBehaviour {
public int someInt;
public string someString;
public float someFloat;
void OnGUI() {
GUI.Button(new Rect(10, 10, 100, 20), new GUIContent("Click me", someInt.ToString(),"

“+someString,”
"+someFloat.ToString()));
GUI.Label(new Rect(10, 40, 100, 40), GUI.tooltip);
}
}

public int someInt;
public string someString;
public float someFloat;
void OnGUI()
{
GUI.Button(new Rect(10, 10, 100, 20), new GUIContent(
“Click me”,
someInt.ToString() +
(string.IsNullOrEmpty(someString) ? “” : "
"+someString) +
"
"+someFloat.ToString()));
GUI.Label(new Rect(10, 40, 100, 40), GUI.tooltip);
}

You can just create the tool tip string as a variable like this:

void OnGUI() {

  if(someVar == null)
  {
    // someVar is null so don't add it to the tool tip
    var buttonString = someFloat.ToString();
  }
  else
  {
    // someVar is not null so add it to the tool tip
    var buttonString = someFloat.ToString()+"

"+someVar.ToString();
}

  GUI.Button(new Rect(10, 10, 100, 20), new GUIContent("Click me", buttonString));
  GUI.Label(new Rect(10, 40, 100, 40), GUI.tooltip);
}
