Balls
Category: Uncategorized / Tags: no tag / Add Comment

I wanted to see just how much math and animation my 6680 could cope with (with Flash Lite) so I put together this file to work it out. It uses an old hit detection fla converted for Flash Lite use so fitted the bill perfectly.

4 bouncing balls at high quality are about the limits of acceptability I think. Obviously, if you drop the quality to medium or low then you could have more on the stage. There are sample Flash Lite files out there already that allow you to examine the handset capabilities but I prefer to be a bit hands-on and just try stuff out. Anyway, you can download the file by clicking on the link below:

I’m happy to email the .fla file to anyone who wants to play with this file. Email me and I’ll send it straight back to you…

UPDATE: After some discussion in the comments section of this entry I’ve produced a new version of the file with the fps calculator from the Flash Lite 1.1 CDK (which was originally converted from Colin’s fps calc file). Download the new version here.

On the 6680 I’m getting about 8.5 frames per second with it…

    Hi Pete could you send me the flas file.

    Thanks,

    Hi Pete, thanks for sharing your findings. I’ve just tried this with circle-line collisions and you’re looking at 2FPS with 1 ball and 5 lines! Future handsets are looking a lot more promising though.

    Hi Herdiansah – to the address you used in the comment form?

    Richard – you’re right, future handsets will be a leap forward, but I hope that the next version of the player is more streamlined too – cleaner coding will make for a smoother playback hopefully…

    Ciao Pete,

    nice test, I am going to try it on my Nokia 6600.
    One question, would performance of such test depends only on processor speed, the FL player or even on OS versioning ? It’s just a curiosity to understand better where things belongs to.

    One more, Pete can I add your blog to the Kero platform as I have done for other people ? http://www.biskero.org/?page_id=21

    Alessandro – thanks for asking about adding my feed to the Kero platform… And, of course, I’d be very chuffed if you did :) Kero rocks btw…

    With regard to the elements that affect the test, I have to be honest and say I don’t know… I’ve tried this app on a 3650, 6600, 6630 and 6680 and the first two are noticeably slower. I guess they’re just slower all round – from screen redraw to working out the math… The main reason I did this was to see whether or not a space invaders game would really work on the mobile platform or not… The jury is still out on that one – early tests indicate that maybe it isn’t the best idea… I’ll keep working on it though!

    Ciao Pete,

    Done! Your weblog is accessible using Kero:

    If you want to change anything let me know !

    I tried it on my 7610 and it was very slow. I’ll try on my 6260 later on today. I was a bit gutted to see it run so slow, to be honest.

    Just tried it on the 6260. Yikes!! Much slower then my 7610. I wonder if the phone temperature and the standard applications running in the background have an effect on the performance.

  9. Pete said: 2005.07.25 15:36

    do you want the .fla cis? You can then adjust the number of balls until it becomes usable…

    I’m not sure if other apps running in the background will affect it that much. I suppose that they will have an imapct – after all, they’re using processor time too as well as memory but I haven’t a clue how much.

    It might be worth adding a fps calc to this file and have people report on the outcome on their handset maybe – could be a cool resource for handset capability then… hmmm…

    a new version of the file with the fps calculator from the cdk (and originally colin moock) is available here.

    8.5 fps on the 6680

    Hi Pete could you send me the flas file.

    Thanks a lot from Italy!

  12. #/cisnky/# said: 2005.07.25 17:04

    6260: loads of fluctuations, but it eventually steadied to 5.6

    I’ll post 7610 results later on this evening.

    Pete can you send me the file. (cisnky at gmail)

    I’m revisiting Flash (Lite) after spending the last 3 years focused on Symbian, BREW & J2ME.

    At 5-8 FPS it seems that Flash Lite is not suitable for action games when native can achieve 15+ FPS.

    Has anyone checked the performace of the next iteration of Lite.

    The url, http://www.petebarrwatson.com/extras/flite/, you provided is not up. When can we expect the files you promised from Flash Forward?

    thanks.

    Hey Julian, long time fella!

    the frame rates are probably not up to full on action games just yet. the platforms are getting better with regard to flash lite though – just from the comments on this thread you can see that over the course of 1 or 2 generations of nokia handsets there has been an improvement. the next gen handsets (n series) will be significantly better again – i hope. Of course, there is also the next version of Flash Lite too… That should make things much easier across the board…

    Guest: Sure – the book is being put together at the moment. there’s an awful lot of content to format and index so I’m sorry it’s a little late. That said, it is free and it will be fairly comprehensive so it’ll be worth the wait… I’ll make a new post about it when it’s completed…

    7610: 5.9 to 6.2

    Pete, Thanks for the FLA.
