libgdx

I want to make a message box that fade when you accept but I don't know how to change the alpha of a font, here is how I do my font: white = new BitmapFont(Gdx.files.internal("data/font/whitefont.fnt"),false); white.setUseIntegerPositions(false); white.setScale(0.025f); white.draw(batchHUD, message.nom+":", 1000*0.1f+(1000*0.8f*0.3f), 625*0.1f+(1000*0.8f*0.625f*0.5f*0.1f)+1000*0.2f); Can anyone help me ? :) I'm sorry for my english, it's not my native language. white.setColor(1, 1, 1, <alpha>); This will change the alpha of the font for all following draws. So you would probably want to set it

I am using next code. This code work fine on desktop version, but on Android device does not. return Gdx.app.getPreferences(PREFS_NAME) always is null. Why? Where I could make mistake? import com.badlogic.gdx.Gdx; import com.badlogic.gdx.Preferences; public class BeatlesPreferences { // constants private static final String PREF_VIBRO = "vibro"; private static final String PREF_MUSIC_ENABLED = "musicenabled"; private static final String PREF_SOUND_ENABLED = "soundenabled"; private static final String PREFS_NAME = "my_app"; public BeatlesPreferences() { } protected Preferences getPrefs() {

I would like the camera to be positioned correctly but I am getting the result below: It seems like when I resize the window, the map does not get rendered properly. Why does that happen? Code: public void render(float delta){ Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); camera.update(); mapRenderer.setView(camera); mapRenderer.render(background); mapRenderer.render(foreground); shapeRenderer.setProjectionMatrix(camera.combined); //draw rectangles around walls for(MapObject object : tiledMap.getLayers().get("walls").getObjects()){ if(object instanceof

i have been having trouble setting padding or something similar to an actor. Cant figure out the way. I guess that I must add something in the skin maybe? I have this TextField: textboxskin = new Skin(); textboxskin.add("textfieldback", new Texture("data/textfieldback.png")); textboxskin.add("cursor", new Texture("data/cursortextfield.png")); textboxskin.add("selection", new Texture("data/selection.png")); textboxskin.add("font", font); TextFieldStyle textfieldstyle = new TextFieldStyle(); textfieldstyle.background= textboxskin.getDrawable("textfieldback"); textfieldstyle.disabledFontColor

I found out there is a new component in LibGDX in nightly builds - TextArea which is part of the scene2d.ui package. It's nice to have a component like this, very easy to use, but what I'm missing is some support for a multi-colored text. I want to highlight some keywords in a text with a different color but I don't know how to do it with current api. There is one method in BitmapFontCache class: public void setColors (Color tint, int start, int end) Javadoc for this method says following: Sets the color of the specified characters. This may only be called after setText(CharSequence, float,

I have a splash screen and a menu screen class that loads all my texture atlases and skins for the menu and processes lots of stuff. If I put the constructor for the menu screen in the SplashScreen constructor or in the create() method of my main game class (MyGame class) then it would pass a lot of time with no splash screen render image on the phone while the whole stuff loads so I have delayed the loading of the menu class to the second frame render (gets called in the SplashScreen render method in the second frame); I simply check if I passed the first frame then I call a method on the

I have a libgdx game that uses scene2d for the UI. I have several ImageButton instances with its own ClickListener . On some devices (only seen it on Samsung Galaxy S3 and Samsung Galaxy S4 Active so far) there is a problem with the event not being delivered unless one clicks twice quickly. Every time a click fails something like the following is logged: 04-22 16:10:09.678: D/InputReader(728): Input event: value=1 when=20897610551000 04-22 16:10:09.678: I/InputReader(728): Touch event's action is 0x0 (deviceType=0) [pCnt=1, s=0.889 ] when=20897610612000 04-22 16:10:09.678: I/InputDispatcher

I'm attempting to put a cube on the screen and light it. I'd like a phong shading on the cube. When I run my code, I can see a background image but no cube. I'm fairly sure the cube itself is correct as I've managed to display it with a solid-colour shader. I've managed to get the shader program to compile but I can't see the cube at all. I don't know if GLES/LibGdx have a mechanism for run-time exceptions but I can't see anything in the logs. I'm assuming that The model is out of the field of view The model is being rendered transparent Both I've tried to pare down my code to where I believe
