I’ve got problem in my work, and I do not know why, Flashcoders mailinglist can’t receive my email, because of wrong email, though all others messages i can receive

So here is email, and please, if someone know the solution, let me know…
Thank you

Hi all,

i’ve made projector (walking insect) with transparent background, and it’s killing all my CPU. there is 3 pieces of them, i’ve tried just 3 squares and it is the same, i can see on my comp redrawing sprites and have 50% CPU (dual processor, 2 GHZ) on other computers, redrawing is not visible, but 100% CPU (or 50% for dual)

I think the problem is creating dynamic mask (flash with desktop), but I dont know how to fix it.
Should I use other projector then Screenweaver?

Btw, i found same problem with some GameHouse game, when it was in fullscreen, all was right, but when i switch off fullscreen
and game was in transparent rectangle (desktop was visible outside the game), mouse was flickering, CPU full, i almost cant do anything, but another games was ok after switching off fullscreen, so this can be problem with some settings maybe…
i dont know, maybe some games was Shockwave, some Flash, really dont know, but I think 3 movings squares on desktop should not
take 100% CPU….

Can someone advice me, what’s is the problem?

Thanks many time..

    I don’t know the whole mechanics of how they do it, but definitely try swf studio for the transparent bg feature, out of all the products , they have hte best performance for that feature.

    I looked into how screenweaver does its transperancy a while ago and yes its resource intensive. They blit it off screen first with a black background then a white. They then take the diference of the two and work out the alpha form that. So it has to render 3 frames per one. At least thats what they were doing when I looked 6 mnths ago. Youl notice some projectors have a freeze mask option wihich save cpu but doesnt allow for dynamic alpha. If the CPU usage is too much then I would skip to a new projector. Sorry dude. you could make sure your movie is as small as possible that way the renders wouldnt be as big, but I doubt that would increase the performance much…..apart from that wait for Apollo, My guess is they have inbuilt a sugar coater version of the player which makes the alpha directly availble to the Apollo platform. Or at least I hope they have.

    Cheers

    Hi, I face a similar problem using MDM Zinc but iceProjector seems to be doing the job well. Maybe you should try the demo version.

    SWF Studio transparency is really great, I break 1 movie into many small movies (each insect has own movie) and now with swf studio it is just 0-2%, but there is problem with creating child windows. I have to use Shell.execute, and every small movie with insect takes 18MB of memory :( in Zinc, it’s just 1 MB of memory, so I’m looking further. IBut as Kirit wrote, Zinf has similar problems :( we will see. I need fast solution, because i’m leaving my company tommorow, and i have to solve this problem…

    Hi,
    I have this problem too.
    1. Each time I drag a transparent window over the desktop it eats next 1-5 Mb, depending on the size of swf.
    2. Another issue with transparency - opening double windows:
    - Shell.execute, …
    - opening dialogs (message boxes) …
    leads to opening of two identical windows.

    Probably the only option is to ask developers to fix bug.
    Please!
