How do I use a font that a user of my screen saver might not have?

Question

I am trying to do a little experiment with fonts. I downloaded a font that was not previously installed on my computer, and am trying to make a "Hello, World!" screen saver with that font(which I installed).
The problem is that I can not even use that font. When I attempt to make a "Hello, World!" screen saver with that font, it uses the default font. Here's the code:
#import "saverView.h"
@implementation saverView
- (id)initWithFrame:(NSRect)frame isPreview:(BOOL)isPreview
self = [super initWithFrame:frame isPreview:isPreview];
if (self) {
[self setAnimationTimeInterval:1/30.0];
//either my mistake is here:
hylianFont = [NSFont fontWithName:@"Ancient Hylian - English" size:20];
attrs = [NSMutableDictionary dictionaryWithCapacity:2];
//NSForegroundColorAttributeName -- [Color green]
[attrs setValue:[NSColor greenColor] forKey: NSForegroundColorAttributeName];
// or it is here:
[attrs setValue:hylianFont forKey: NSFontAttributeName];
displayer = [[NSAttributedString alloc] initWithString:@"Hello, World!" attributes:attrs];
return self;
//... more stuff I do not use...
//simply draws "Hello, World!" in green at the top right of the screen.
//meant to draw it in the different font, but draws it in the standard font.
- (void)animateOneFrame
[displayer drawInRect:[self bounds]];
return;
@end
Where did I mistype?

I think I solved the problem. I just put the font and the screen saver in a pkg file, and make the pkg file install the font. Or I guess I could keep the font in my screen saver and test it that way. Either way, I found the answer.
