PlaySprite(10, 0);

Sometime, it will take a mistake. the animation just stay the frame 1, and can't play. I am very puzzled.
Can anyone give a hand ? I don't know where is wrong. I exam my program many times ,but I can't find the reason. maybe it's a bug of AppGameKit, hope someone can give a hand.

This kind of bug don't show every time. so It's very difficult to find the reason.

I haven't experienced any issues as yet... Are you checking to ensure its not already playing?

+ Code Snippet

if GetSpritePlaying(CharacterSprite) = 0
     PlaySprite(CharacterSprite, 4, 1, 10, 12)
endif

I just now made a test about GetSpritePlaying(). it's useless for this problem.
I guess SetSpriteActive() may have relation with the problem. but I'm not sure about it.
Hope to receive more suggestions.

PlaySprite(spriteID,fps)
PlaySprite(10, 0)

You are telling AppGameKit to play sprite 10 at zero frames per second. Try this:
PlaySprite(10,30,1) the 1 will loop the animation (change to zero if you don't want it to loop)

I will add that 30 might be a little (or more than a little) frames too much.

Well doesn't that depend on the type of animation? I have sprite sheets that I run at that speed

Depends on what do you need I guess

I have a background of a stadium, where crowd is moving. I used 10 FPS or even lower, so they're not jumpy.

@baxslash, the problem sometimes happens and sometimes don't happen. and I can't find the reason.
Sometimes it is just well. but for a very few situation, the animation just stay frame 1,and stop the animation.

Any chance you could provide an example when it doesn't work? Just a simple one maybe if you can narrow it down?

agk:

laySprite( m_iID, fFps, iLoop );

I just call the function, only one line.

Depending on how you are initiating PlaySprite, you must ensure you are not already playing the animation (as per my first post). You mention that you are using PlaySprite on its own (only one line), this is likely your problem. Post your code and perhaps we can take a look.

You maybe can't understand my code. Because I use C++, and enclose a class CSprite.

I guess you have a code to StopSprite somewhere, right?

Just analize your code, step by step what's being done. It might be a simple programming failure.

I could be wrong but is that a yellow gremlin in your code halley

?

I can't see the problem but then maybe it's not in the code here. I would write a small separate, self contained program that shows the problem and post it on the bug board.

Since you are not looping, are you using SetFrame() to reset the sprite back to beginning of the animation, otherwise it will forever be at the end. Also since you are using the sprite class are you calling Update() along with Draw(), or using a sprite manager?

@Paul, I called Stop(), but in the front of Play(10, 0).
I called SetActive() when user tap pause button. I guess the problem has relation with this function.

I didn't call SetFrame() , and the animation just stay frame 1,and can't play. I mean it didn't play any times.

Draw() won't update the animation, are you calling Update() on the sprite?
