Libdx.Texture不包含0参数构造函数

Question

好的伙计们，我正在libgdx中制作一个角色编辑器，它基本上是动画命中箱的编辑器，到目前为止它起作用，它保存了一个json文件，但每当我点击加载时，它就会崩溃。

我知道错误是指libgdx.texture不包含0参数构造函数，但我想知道我该怎么做。

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.SerializationException: Class cannot be created (missing no-arg constructor): com.badlogic.gdx.graphics.Texture
Serialization trace:
keyTable (com.badlogic.gdx.utils.ObjectSet)
textures (com.badlogic.gdx.graphics.g2d.TextureAtlas)
atlas (hitbox.Animations)
animation_list (hitbox.Character)

这是我的代码：

public void Save(String s)
    {
        Json json = new Json();
        String character_string = json.toJson(character);
        FileHandle file = Gdx.files.absolute(s);

        file.writeString(character_string, false);
    }

    public void Load(String s)
    {
        FileHandle file = Gdx.files.absolute(s);

        if (file.exists())
        {
            String character_string = file.readString();
            Json json = new Json();
            character = json.fromJson(Character.class, character_string);
        }
    }

public class Character {

    public List<Animations> animation_list;

    public Character()
    {
        animation_list = new ArrayList<Animations>();
        animation_list.add(new Animations());
    }

}
public class Animations {

public List<Frame> frame;
public String name_of_animation, path_to_atlas;
public int index, last_frame, number_frames;
public TextureAtlas atlas;
public Animation animation;
//"data/ATHENA/walking.atlas" path to atlas

    public Animations()
    {
        frame = new ArrayList<Frame>();
        frame.add(new Frame());
        name_of_animation = "null name";
        path_to_atlas = "null path";
        index = 0;
        last_frame = 0;
        number_frames = 0;
    }

    public void AddAtlas(String name)
    {
        FileHandle handle = Gdx.files.absolute(name);
        if (handle.exists())
        {
            atlas = new TextureAtlas(handle);
            animation = new Animation(1/15f, atlas.getRegions());
        }
    }
