libgdx

问题 From what I understand when reading other peoples code on how to make different screens. You do a main handler class sort of... And then create a new class for each screen. The thing that confuses me is that whenever you create a new screen, you have to redefine everything that's going to be rendered, like SpriteBatch, sprites, fonts, etc. Is there any way to reuse these kind of things in all screens? I mean, if I have 10 screens, and want to be able to draw text on every screen. Is it really

问题 I am trying to add google ad banners for my libgdx android game. After following the guide https://github.com/libgdx/libgdx/wiki/Google-Mobile-Ads-in-Libgdx-(replaces-deprecated-AdMob) and importing "google-play-services_lib" the game can't be started anymore.

问题 I have an application in which i want to take the screenshot of the game screen and save it as an image and upload to Facebook. I am using Libgdx and my focus is android. Can anyone help me that how to take screenshot of the game screen programmatically and save it as an image ?? 回答1: It is now fairly easy. Libgdx provides an example, which can be found here. I had to add one statement to get it working. The image could not be saved directly to /screenshot1.png . Simply prepend Gdx.files

问题 I am using the LibGDX headless backend to run jUnit tests. This works well for certain tests, but if I try to create a new Texture('myTexture.png'); , I get a NullPointerException. The exact error is: java.lang.NullPointerException at com.badlogic.gdx.graphics.GLTexture.createGLHandle(GLTexture.java:207) To keep things simple, I created a method that does nothing other than load a texture: public class TextureLoader { public Texture load(){ return new Texture("badlogic.jpg"); } } Then, my

问题 What I want to have is the Bitmap Font to change in size accordingly when changing screen sizes. What I mean is on my computer, the font appears rather large, but on my phone, it is a little font that is harder to read. I could change the size, but I want it to look similar on all screens, instead of having it large on one screen and smaller on another. Here is my code to see what I have to work with: public void render() { //score system scoreFont.setColor(1.0f, 1.0f, 1.0f, 1.0f); scoreBatch

问题 This code makes image flicker while moving left,right,down or up. public class MoveSpriteExample extends GdxTest implements InputProcessor { Texture texture; SpriteBatch batch; OrthographicCamera camera; Vector3 spritePosition = new Vector3(); Sprite sprite; public void create() { float w = Gdx.graphics.getWidth(); float h = Gdx.graphics.getHeight(); batch = new SpriteBatch(); camera = new OrthographicCamera(); camera.setToOrtho(false, w, h); texture = new Texture(Gdx.files.internal("data

问题 I am creating a Java game with libgdx. Really liking the engine so far but I noticed an issue when dragging the game window. Rendering seems to stop (which is okay) but I cant find any events that get called during this state. Is there any way I can trap it? It not a big deal for rendering as I cap the deltaTime, but for input the keyUp events don't get fired which messes up my movement code for the player (if you are to release the keys while dragging the window). Is there anything I can do?
