Zscript HUD Font

[ArrivedHero]

Hey, I've been trying to create my own HUD with my own fonts but of course I am running into trouble. I am following along with how the DoomStatusBar class added it's own fonts in it's Init() function but I keep getting a "expression must be a modifiable value" error.

 

Here is my code.

 

class TheLastIconHUD : BaseStatusBar
{
    HUDFont visor;
    HUDFont damageEffects;
    

    override void Init()
    {
        Super.Init();
        SetSize(0, 1920, 1080);
        
        Font fnt = "TESTFONT";
        visor = HUDFont.Create(fnt, fnt.GetCharWidth("0"), Mono_CellLeft, 1, 1);
        fnt = "DAZEFONT";
        damageEffects = HUDFont.Create(fnt);
    }
    
    override void Draw(int state, double TicFrac)
    {
        super.Draw(state, TicFrac);
        
        DrawImage("hud0", (0, 0), DI_ITEM_OFFSETS);
    }
    
}

 

What exactly am I doing wrong?

Update: Found the problem. I had to add the updated version into the ZScript file "version '4.1.2'". I know, I'm a version behind but I'm working on it.
