[android-developers] Re: 2D Double Buffering in Android 1.5 (with Canvas?)
I only concern of my animation quality ... Caused the current approach give me a flickering effect (yes which is quite disturbing for viewing).

This approach is very different from my desktop Java experience, which in turn it's quite hard for me to fine tune my game performance.

[android-developers] Re: Animated Sprites For Games
Thanks taking the time to write down those guides... that helps me alot!!! Cheers, Avatar Ng --- On May 26, 4:11 am, Robert Green rbgrn@gmail.com wrote: It's usually a little more complicated than that because you need to have it handled by your loop and then there is variable timing, etc so I wrote this to get people started: http://www.rbgrn.net/content/253-main-loop-suitable-stable-animations It has some code that you may want to use. Just load up all of your frames into an array of bitmaps and then have your draw code draw the appropriate bitmap into the correct spot, which is as easy as canvas.draw(bitmap, x, y, paint). If you need to scale or rotate it, you may want to use a matrix to draw and have it position (translate) scale and rotate. I just helped someone else doing the same thing. It's not that hard after you've implemented it once. There is some good discussion in the top comments on this post as well -http://www.rbgrn.net/content/54-getting-started-android-game-development Good luck!

lol ... icic So I assume double buffering is taken care behind the scene (I saw your name in the EGLDisplaySurface.cpp code review, now I know why you are so bz to reply) Anyone mind to show us what;s the right way to use SurfaceView in a game loop ... in order to beneficial from Double-Buffering ... thanks Cheers Avatar Ng - On Jun 11, 5:13 am, Romain Guy romain...@google.com wrote: Not just SurfaceView, regular views also benefit from double buffering.

Hi, thanks everyone for your input ... I'll try up the suggestions. Cheers, Avatar Ng On Jun 12, 2:35 am, Robert Green rbgrn@gmail.com wrote: I'm seeing 9fps on your app. That's way too slow. I have 2 full screen layers, many sprites, full sound and 2 A* algorithms running at 45 FPS. There are many things you must know to do efficiently. I'm not going to list everything I've done here because it would fill up pages but if you take a look at my blog I wrote about lots of it.http://www.rbgrn.net/content/290-light-racer-20-days-32-33-getting-gr... talks about some of that. I'm not using OpenGL ES, just a plain old Canvas. Z buffering probably would have been much easier with a 3D library, so if it's just as fast, I'd recommend doing that. Either way though, you need to be performance-conscious or you'll have a sluggish game.
