Thread: Sprite flickering in 1.07b - solution found

    Sprite flickering in 1.07b - solution found

    1.07b is counting sprite animations from 0, we lowered the animation frames by one and it works.
    BTW, the problem occurs in the provided sample as well.

    Sprite flickering in 1.07b - solution found

    Umm... may I ask what exactly was the problem from? Your reference seems kinda vague.

    Was this something that was an issue in the release it's self or from another project?

    Sprite flickering in 1.07b - solution found

    All sprites in 1.07b started flickering. It was all Okay in unDelphiX6 that we used before. It seems that 1.07b is counting animation frames from 0 (previously it was 1). So reducing the animation count by 1, the problem goes away.

    Please tell me where is this change? DXSprite unit or the edit form no changed from version 6 to 7. Thank you

    Hi Ijcro,

    I contacted you by mail, but if you did not get it, please drop me a mail at: info1848@yahoo.com

    When we upgraded, all sprites started flickering, we figured that it was because the engine displayed an empty animation frame.
    What we did IIRC is that we reduced the AnimCount for all our sprites by 1 and the flickering went away. I will double-check this with my coworker who is responsible for the graphics programming.

    Still flickering

    Anyone know how to work around the flickering sprite bug in undelphix? Driving me mad.

    Like the other guy said, it seems to be drawing a blank frame after the animation is complete, then returning to first frame causing a "flicker". It has doen it with me since the very first undelphix and is still happening in 1.07c

    I tried contacting jaro at undelphix@micrel.cz but it won't send

    Actually after closer inspection,flickering started in 1.07

    The first undelphix works fine, no flickering. I have also noted that with 1.07c, the sprites are altered too.

    For example, 1 black 25*25 cube with a yellow line running through the middle. In earlier versions, the line is correct at 5 pixels wide. In 1.07c, the line is about 3 pixels wide, smoothed out and looks completely wrong.

    Didn't go into it much really, the flickering is the main issue. I have gone back to early version of undelphix

    Thank you.

    It is 1.07c.

    I can prepare a demo for you. Earlier versions had 0 flicker. But the sprites flicker when animated in 1.07 onwards (b and c for sure).

    Do you want a demo with exe?

    also...

    I can demonstrate the yellow line thing here with screenshots



    Above is the picture in delphix and early versions of undelphix (100% correct)



    Above is 1.07c. As you can see the yellow line has changed (and even cuts out on the left, the rest of it is different too.

    Thank you.
    Please demo in source (no exe, can be very simple) into prototype project included in source unDelphiX.
    I can test it directly with new prepared version 1.08.
    Regards
    Ijcro.
