问题 How come my objects constructor for player is not called during deserialization? Is there a way to invoke the constructor using this approach? Load json into java object using com.badlogic.gdx.utils.Json .. LevelModel ld = new Json(). fromJson(LevelModel.class, Gdx.files.internal("levels/level1.json")); setLevel(new Level(ld)); Heres my JSON .. { "gravity": { "x": 0.0, "y": 0.0 }, "sounds": [ BGMUSIC ], "player": { "maxSpeed": 10.0 } } LevelModel.java looks like this .. public class

问题 I have made a free android game and I wanted to add a banner to it. I followed this tutorial and I don't know why it won't work. When I run my game on the emulator in LogCat I see a message "Ad is not visible. Not refreshing ad." and when I install the game on my phone I also don't see any ads. Here is my main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/res-auto" android

问题 I have a Dialog : Dialog dialog=new Dialog("",style); dialog.setSize(400, 500); dialog.setPosition(Gdx.graphics.getWidth()/2-200, Gdx.graphics.getHeight()/2-300); I added a two button in it: dialog.button(stopButton); dialog.button(goButton); My problem is that I can not change the position of buttons, not even if the imposed manually the buttons remain in the same position. how could I do to solve the problem? Thank you 回答1: The buttons of a libgdx dialog get added to the ButtonTable of the

问题 I want to implement a cool effect, when there is an explosion the music gets slightly slower for a moment. The Music class of libgdx doesn't allow changing the pitch of the sound, I tried using the Sound class instead of the Music to play my music but its very slow at loading the files ( 5 sec for a 5 mb file, on Desktop! ). So, the question is if there is a way to workaround this, or if there is an external library, that works both on desktop and android and can work along with libgdx. 回答1:

问题 I'm creating menus in my game specially rectangles with rounded corners and borders. I can do this with a shape renderer but I cannot mix shape renderer and sprite batcher. At the moment my resolution seems to be using large shapes as PNG's and scaling them BUT on a lot of devices this produces blurry corners. I've read my tutorials on Meshes, shaders, using the shape renderer after the sprite batch (complication layer and performance impact), 9-patch (Border goes blurry, can't do gradients

问题 so I'm currently programming a little game in Java with libGDX. I want the players texture to directly rotate to the mouse position. Unfortunately my code doesn't work, and I have absolutely no idea why not. So, I call this method in the Update method of the player: private void CalculateRotation() { rotation = Position.angle(input.getTranslatedMousePos()); } The Position is just a Vector2 with the players position. I get the translatedMousePos like this: public Vector2 getTranslatedMousePos(

问题 How can I draw text (font) on top of my static box2d body? Background: Im able to draw sprites on top of bodies correctly. I do this by having a box2dSpriteBatch which is projected on box2dCamera like so box2dSpriteBatch.setProjectionMatrix(box2dCamera.combined); And then simply rendering the sprite in the correct spot using getPosition of the body. But if i try the same way for fonts, unfortunately it scales incredibly large, and if i try to scale the font down it doesn't appear. So im

问题 I have a pre-made json file that I want to test out. This Json file will be modified so I want to read/write. I noticed that internal is read-only. So I want to save my Json file in the local storage(manually through eclipse or OS(windows 8)) such that I can access through files.local(). Does anyone know the address of the local storage defined by libgdx? So that I can save my pre-made Json file? This is for testing only! If there is a better way for me to test out my json file (read/write)

问题 I'm building libgdx's gdx-invaders sample. There are two projects: gdx-invaders - the base project, which runs as a desktop Java application gdx-invaders-android project - depends on gdx-invaders, and runs as an Android application I'm new to Eclipse, but based on the best tutorials I could find, took the appropriate steps to get these two projects referencing the appropriate libraries (gdx.jar, etc.), and to get them using Android 2.2. I also tried basic fixes like cleaning before building,
