问题:

I am trying to make a Table that has a Skin based on libgdx's default LabelStyle and BitmapFont through the use of a json file. (this file is supposed to hold the references of these two objects) In doing this I am getting some unclear errors. For instance:

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.SerializationException: Error reading file: ui/uiskin.json         at com.badlogic.gdx.scenes.scene2d.ui.Skin.load(Skin.java:96)         at com.badlogic.gdx.scenes.scene2d.ui.Skin.<init>(Skin.java:73)         at com.naitsirc.Interpolation.Test.show(Test.java:47)         at com.badlogic.gdx.Game.setScreen(Game.java:61)         at com.naitsirc.Interpolation.InterpolationTest.create(InterpolationTest.java:9)         at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop(LwjglApplication.java:136)         at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:114)     Caused by: com.badlogic.gdx.utils.SerializationException: Error reading file: ui/uiskin.json         at com.badlogic.gdx.utils.Json.fromJson(Json.java:662)         at com.badlogic.gdx.scenes.scene2d.ui.Skin.load(Skin.java:94)         ... 6 more     Caused by: com.badlogic.gdx.utils.SerializationException: Serialization trace:     font (com.badlogic.gdx.scenes.scene2d.ui.Label$LabelStyle)         at com.badlogic.gdx.utils.Json.readFields(Json.java:762)         at com.badlogic.gdx.utils.Json.readValue(Json.java:865)         at com.badlogic.gdx.scenes.scene2d.ui.Skin$1.readValue(Skin.java:418)         at com.badlogic.gdx.utils.Json.readValue(Json.java:809)         at com.badlogic.gdx.scenes.scene2d.ui.Skin$2.readNamedObjects(Skin.java:439)         at com.badlogic.gdx.scenes.scene2d.ui.Skin$2.read(Skin.java:428)         at com.badlogic.gdx.scenes.scene2d.ui.Skin$2.read(Skin.java:424)         at com.badlogic.gdx.utils.Json.readValue(Json.java:839)         at com.badlogic.gdx.scenes.scene2d.ui.Skin$1.readValue(Skin.java:418)         at com.badlogic.gdx.utils.Json.fromJson(Json.java:660)         ... 7 more     Caused by: com.badlogic.gdx.utils.GdxRuntimeException: No com.badlogic.gdx.graphics.g2d.BitmapFont registered with name: default-font         at com.badlogic.gdx.scenes.scene2d.ui.Skin.get(Skin.java:145)         at com.badlogic.gdx.scenes.scene2d.ui.Skin$1.readValue(Skin.java:417)         at com.badlogic.gdx.utils.Json.readFields(Json.java:755)         ... 16 more*

This is where I create my skin with the json:

public void show() {     Gdx.input.setInputProcessor(stage = new Stage());      skin = new Skin(Gdx.files.internal("ui/uiskin.json")); // HERE      container = new Table();     table = new Table(skin);      for(int i = 0; i < interpolationNames.length; i++){         //table.row();         table.add(interpolationNames[i]); // I am trying to populate these table cells     }      ScrollPane pane = new ScrollPane(table);     container.add(pane);              stage.addActor(container);      renderer = new ShapeRenderer(); }

My json file:

{     com.badlogic.gdx.scenes.scene2d.ui.Label$LabelStyle: {         default: { font: default-font, fontColor: white }     },       com.badlogic.gdx.graphics.g2d.BitmapFont: {         default-font: { file: default.fnt }     } }

What am I doing incorrectly?

Note

I seem to have the same problem as here but what I did is the same thing, and its not working.

回答1:

The problem is with the order of the objects in my json file and also I missed some required objects for the ScrollPane and Color. In addition I needed to add default.fnt and default.png to my assets folder from here. Basically its supposed to look like this:

{     com.badlogic.gdx.graphics.g2d.BitmapFont: {          default-font: { file: default.fnt }      },     com.badlogic.gdx.graphics.Color: {         white: { a: 1, b: 1, g: 1, r: 1 },     },     com.badlogic.gdx.scenes.scene2d.ui.Label$LabelStyle: {         default: { font: default-font, fontColor: white }     },     com.badlogic.gdx.scenes.scene2d.ui.ScrollPane$ScrollPaneStyle: {         default: { vScroll: default-scroll, hScrollKnob: default-round-large, background: default-rect, hScroll: default-scroll, vScrollKnob: default-round-large }     } }

This said I still don't understand why a certain order is required nor do I know how to find out which specific objects need to be placed in the json file. The only way I figured out that I need these specifically is by the errors Eclipse gave me.
