我正在尝试在一个练习项目中加载一种字体，libgdx就像这样。

package peace.at.steamd.screens;

import peace.at.steamd.Steamd;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Screen;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.TextureAtlas;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.Skin;
import com.badlogic.gdx.scenes.scene2d.ui.TextButton;
import com.badlogic.gdx.scenes.scene2d.ui.TextButton.TextButtonStyle;

public class mainmenu implements Screen{
Steamd game;
Stage stage;
BitmapFont black;
TextureAtlas atlas;
Skin skin;
SpriteBatch batch;
TextButton button;
public mainmenu(Steamd game){
    this.game= game;

}

@Override
public void render(float delta) {
    Gdx.gl.glClearColor(1,1,1,1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
    stage.act(delta);

    batch.begin();
    stage.draw();
    batch.begin();

}

@Override
public void resize(int width, int height) {
    if(stage== null)
        stage= new Stage(width,height,true);
    stage.clear();
    Gdx.input.setInputProcessor(stage);
    TextButtonStyle style= new TextButtonStyle();
    style.up= skin.getDrawable("buttonnormal"); 
    style.down= skin.getDrawable("buttonpressed");
    style.font=black;
    button=new TextButton("Press Me",style);
    button.setWidth(400);
    button.setHeight(300);
    button.setX(100);
    button.setY(100);
    stage.addActor(button);
}

@Override
public void show() {
    batch=new SpriteBatch();
    atlas=new TextureAtlas("data/button.pack");
    skin= new Skin();
    skin.addRegions(atlas);
    black= new BitmapFont(Gdx.files.internal("data/custom.fnt"),false);
}

@Override
public void hide() {
    dispose();
}

@Override
public void pause() {
    // TODO Auto-generated method stub

}

@Override
public void resume() {
    // TODO Auto-generated method stub

}

@Override
public void dispose() {
    batch.dispose();
    skin.dispose();
    atlas.dispose();
    black.dispose();
    stage.dispose();

}

}

custom.fnt 位于正确的目录中并已链接等。但是，当我运行示例时，出现此错误。

当它到达该点时，它会尝试加载字体。我使用 hiero 网络启动器来创建字体，字体文件本身并没有什么特别之处。有任何想法吗？
