使用FreeTypeFontGenerator后，仅释放生成器是否足够？需释放BitmapFont吗？

Great question—this is a super common gotcha when working with libGDX's FreeType font tools! Let's break this down clearly:

• FreeTypeFontGenerator.dispose() only cleans up the generator's own resources
  When you call this method, it releases things like the underlying FreeType library handles and the loaded font file data that the generator uses to create fonts. Crucially, it does not touch any BitmapFont objects you've already generated with it.

• BitmapFont objects hold their own GPU resources that need manual disposal
  Every BitmapFont you create is paired with a Texture (or set of textures) that stores the rendered glyphs. These live in GPU memory, and the generator has no way to track or clean them up for you. If you skip calling bitmapFont.dispose(), those textures will linger in memory, leading to leaks that can cause performance hits or even crashes over time—especially if you generate multiple fonts during your app's lifecycle.

Here's a quick example of the proper way to handle disposal:

// Initialize generator and create a font
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("my-font.ttf"));
FreeTypeFontParameter params = new FreeTypeFontParameter();
params.size = 32;
BitmapFont gameFont = generator.generateFont(params);

// Use the font in your UI/rendering...

// When you're done with the font (e.g., switching scenes, closing a screen)
gameFont.dispose(); // Releases the font's texture resources

// When you'll never need to generate more fonts with this generator (e.g., app shutdown)
generator.dispose(); // Cleans up the generator's internal resources

One quick note: If you dispose the generator first, you can still use any existing BitmapFont objects you created with it—you just can't generate new ones. The fonts' textures are independent once generated.
