Loading a font at runtime?

Unity Engine
1

Hello there,

how would I load a font at runtime? What I wanna do is a simple main menu with text-buttons and I would like to avoid having to set the font manually in the inspector but instead load it automatically. I’ve been trying the following, but I always get a wrong font (looks like the standard arial) and the background is all messed up…

using UnityEngine;
using UnityEditor;


class MainMenu : MonoBehaviour
{
    public GUIStyle style = new GUIStyle();
    public int cx = 0;
    public int cy = 0;

    public int btnWidth = 120;
    public int btnHeight = 35;

    public void Start()
    {
        style.normal.background = new Texture2D(120, 35);
        style.hover.background = new Texture2D(120, 35);
        style.normal.textColor = new Color(0f, 0f, 0f);
        style.hover.textColor = new Color(0f, 0f, 128f);

        // the following seems to (silently) fail
        style.font = (Font)Resources.Load("BADABB__"); // badaboom font
        style.fontSize = 34;
    }

    public void OnGUI()
    {
        cx = (Screen.width / 2) - (btnWidth / 2);
        cy = Screen.height / 2;
 
        if (GUI.Button(GetRect(-87.5f), "New Game", style)) { Application.LoadLevel("Level1.0"); }
        if (GUI.Button(GetRect(-52.5f), "Load Game", style)) { Application.LoadLevel("Load Menu"); }
        if (GUI.Button(GetRect(-17.5f), "Save Game", style)) { Application.LoadLevel("Save Menu"); }
        if (GUI.Button(GetRect(17.5f), "Options", style)) { print("this takes you to the options menu"); }
        if (GUI.Button(GetRect(52.5f), "Exit", style)) { print("this exits the game"); }
    }

    public Rect GetRect(float yOffset) { return new Rect(cx, cy + yOffset, btnWidth, btnHeight); }
}

I’m totally new to coding in Unity, but not to coding in general. What would be correct way to do it in Unity?

Is the font located in a folder named ‘Resources’?

Otherwise it won’t load.

Thanks a lot, that solved the problem. I expected Unity to throw an error if it’s unable to find a file.

4

nope
but you can always check for != null after loading to know if it failed

5

True. Is this some special case for the Resources.load() function or does Unity never report missing files?

6

it does not throw exceptions normally on functions that “find” stuff, it will return null to signal that it wasn’t found (exception bring some serious overhead with them)

7

ah, ok. thx. I’m currently mostly developing in AS3, so I’m used to errors being thrown for everything. :wink:

Unity will throw error too: NullReferenceException if you use such null initialized variables :wink:

In case of the font you were just lucky that there is a default font active that will jump in if none is specified

TonyD Thanks a lot it helped me out too.
