Android :: Moving Background Image For Game

Nov 11, 2010

I'm currently developing an Android game where the user controls a plane and evades obstacles. I'm using simple draw commands into a Canvas.

I want to know what is the best way to move a background image to give a sense of speed to the game. Is there a way to make the background- image repeat endlessly or should I load the image twice and move them one behind the other one. Can anyone guide me on this one?

Android :: Draw Background Image With Moving Foreground Graphics?

Aug 28, 2010

I would like to know what the best way would be to draw a background image (this would be pretty much static) and a foreground object which would move depending on user input in Android?

Sort of like a side-scroller game (when the foregroudn object needs to animate and change a lot more than the background).

Android :: 2d Background Image On 3d OpenGL Game

Feb 12, 2009

I need to draw a background of 320 x 480 (fullscreen) for a OpenGL game. What I did was to stretch the texture to 512 x 512 and mapped it to 320,480 quad and then drew the rest of the game elements. I tried changing the texture image to 256x256 and no noticeable improvement in speed. Game was horribly slow even on the real device. It is actually slower on the device than on the emulator... I think i am the first one to have such a situation.. I am drawing a max of 12 triangles only 2 for background and rest are 64 x 64 textures. on 5 quad made with 10 triangles. I have disabled Depth, Lighting already. Only blending enabled as I use transparent PNG for texture of sprites. render cycle is like this - draw the background - draw the sprites (only 5) [with 10 triangles only] - swapbuffer... Please don't advice me to use 2d canvas, bitmap etc... I need to do it in OpenGL only. don't think OpenGL ES 1.0 is so incapable that it can't give me atleast 25-30 fps with just 12 triangles which you one 256x256 texture and one 64x64 textures (used by 5 quads...

Android :: Game Doesn't Work Due To Thread Background Processes

Mar 8, 2010

I have written a very simple game with some simple animations, but I've noticed that when the phone checks email, or several other apps are running, the animations that update in my thread start behaving slowly or choppy. This is a problem as the game mechanic requires some careful timing of your screen touches based on the animations. So if it starts behaving erratically, the game doesn't really work well - and isn't much fun.
Is there a way to prevent this? Can my threads have a higher priority when they need to run?

Android : How To Use Nine Patch Image In Droid Game?

Jun 21, 2010

I am trying to use a nine patch image as a background in an android game. The image expands well in multiple resolutions but, my game has slowed down by 10 fps. I used to get a consistent 45 to 50 fps now I get 35 fps. The question is when we use a nine patch as a drawable and set it as a background in a view does it have any performance implications as opposed to a plain bitmap drawing.

Android :: Moving Cursor Adapter Cursor Creation To Background Thread

Mar 29, 2010

The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.

Android :: Background Image For Wrap_content

Sep 6, 2010

I created a custom background image and wanted to use it as the background for a layout that has height of wrap_content. However, the total height of the contents of within that layout are much less than the height of the background image.

When I set it as the background in XML via android:background="@drawable/image", I noticed that it displays the entire height of the image, although the height of the actual contents are much shorter.

Android :: Background Image Placement?

May 6, 2010

I'm trying to set my root LinearLayout element (which is set to fill_parent in both dimensions) to have a background image which is always located in the lower left corner of the screen no matter the orientation of the device. It would be excellent if there were some way to set the background image position such as that which you can do with css using "background-position: left bottom;" but I'm not seeing a way to achieve this in Android. Is there a way to do this?
