libgdx - how to add background image in stage?

阅读更多关于 libgdx - how to add background image in stage?

I am learning libgdx but i am stuck at a point.. I have added a button in my stage , now i want to add a image in the stage so that the image looks as the background image to the button.i mean to say that the button should lie on the image. I have been looking tutorials but not been able to do that. How can it be done? any help? The only thing you need to do is to draw the background, before drawing the Button s. There are a few possible ways to do that: - You can add the background as an Image (subclass of Actor ) to the Stage and use the z-index to make sure it is drawn as a background. -

How to reload libgdx unmanaged Texture after OpenGL context loss

阅读更多关于 How to reload libgdx unmanaged Texture after OpenGL context loss

问题 I'm downloading images over the network and add them to my libgdx UI as Image actors using this: Pixmap pm = new Pixmap(data, 0, data.length); Texture t = new Texture(pm); TextureRegion tr = new TextureRegion(t,200,300); TextureRegionDrawable trd = new TextureRegionDrawable(tr); Image icon = new Image(); icon.setDrawable(trd); Given this I need some way of reloading the texture data since it is lost when the OpenGL context is lost (e.g. because the screen goes to sleep). I've tried making my

libgdx game crashes on some devices

阅读更多关于 libgdx game crashes on some devices

Right after start of app, my app crushes without error message on a device. This only happens on Samsung Note 1(at least, can't test on all devices), but not on Motorola Moto G or Galaxy s4mini. The only hint I get is in the debugger. I pasted it below. What exactly is happening and why it crashes only on some devices? Edit: it crashes also on return to the app from "running apps" menu. Note 1 has CyanogenMod installed. Maybe this has something to do with the crashing. Edit2:Another observation: note 1 allocates only a half of the memory as the other two devices. Has this anything to do with

Loading texture in libgdx android using file in res?

阅读更多关于 Loading texture in libgdx android using file in res?

问题 In LibGdx, texture image is stored in asset folder and loaded using following code. Texture texture = new Texture(Gdx.files.internal("image/someImage.jpg")); I have different texture for different screen resolution, so I want to use Android "res/" directory for saving texture image, which helps to load appropriate image file for appropriate resolution.

Efficient 3D block rendering with Libgdx

阅读更多关于 Efficient 3D block rendering with Libgdx

To start with,I am pretty new to 3D programming and libgdx. I looked at a few tutorials and I already render the scene I want. I have some 1x1x1 blocks, created with ModelBuilder.createRect() for every visible face, so if another block covers a face of this block, there is no rect created for this block. Also the top and bottom rect is not needed, as I can never see them (except for the floor). So I thought, that this is pretty efficient. I also have Backface culling enabled and I do Viewfrustum culling . However, if I look in a direction, where many blocks are in my viewfrustum the FPS go

Can I have Android Views overlayed on top of the libgdx GL surface?

阅读更多关于 Can I have Android Views overlayed on top of the libgdx GL surface?

I would like to display some custom views ( e.g. TextViews with Arabic/Asian text) on top of everything that happens in libgdx's OpenGL Surface (<--I assume it's a surface view). Is this possible? How? The motivation is that I have a proven component for displaying text in my existing code and I would like to keep using this. I have used other GLSurfaceViews with View hierarchies before. Just wondering how/if this can be done in libgdx. Performance doesn't matter all to much because the "game" in libgdx is a simple puzzle game, and when the text views are shown, the game is pretty much paused.
