C# GUI.Tooltip If Statement
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(),"\n"+someString,"\n"+someFloat.ToString()));
GUI.Label(new Rect(10, 40, 100, 40), GUI.tooltip);
}
}
which value do you want to check if null, and if null which parts of the tooltip do you not want to display.
Also I'm pretty sure Tooltip doesn't take 3 strings as an argument so you will probably get errors from that too.

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) ? "" : "\n"+someString) +
"\n"+someFloat.ToString()));
GUI.Label(new Rect(10, 40, 100, 40), GUI.tooltip);
}
I don't see enough people making use of the ? operator, this is what I would do aswell.

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()+"\n"+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);
}
someVar would be the variable you want to check. You said you want to check if a variable is null so I assume you already have this variable? Or do you want to set a flag(bool) and check if its true or not?
If you want to check if the strings you want to pass are 'existing' check Leslie Young's answer
