Could you post the image that you see, and the expected image ? thanks.

Hi Riq,
Its more noticable when its being animated, but I can explain a little more detail of what is happening. Let say you have characters that can walk left and right on the screen.
The characters are using 1 sprite sheet, the characters going right (its original animation) everything is ok. The characters going left (using FlipX on the sprite) the character bounces back and fourth. It just looks like its ignoring offsets, looks like the animation frames are all aligned on the right edge instead of keeping them centered with offsets.
I can try to make a movie and send you a link if you need to see it, I will also try to debug the issue myself as well.
thanks
probably it is a bug. Could you open an issue ? and if possible, try to attach the code / images to reproduce it. thanks.

Here is the code to reproduce the bug. Thanks!
CGSize s = [[CCDirector sharedDirector] winSize];
// parents
CCSpriteSheet *sheet = [CCSpriteSheet spriteSheetWithFile:@"animations/grossini.png" capacity:50];
[self addChild:sheet z:0 tag:kTagSpriteSheet];
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"animations/grossini.plist"];
CCSprite *sprite1 = [CCSprite spriteWithSpriteFrameName:@"grossini_dance_01.png"];
[sprite1 setPosition:ccp( s.width/3, s.height/2)];
CCSprite *sprite2 = [CCSprite spriteWithSpriteFrameName:@"grossini_dance_02.png"];
[sprite2 setPosition:ccp(50,50)];
sprite1.flipX = TRUE; // THIS CAUSES THE BUG
[sheet addChild:sprite1];
[sprite1 addChild:sprite2];
NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i < 15; i++) {
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"grossini_dance_%02d.png",i]];
[animFrames addObject:frame];
}
CCAnimation *animation = [CCAnimation animationWithName:@"dance" delay:0.2f frames:animFrames];
[sprite1 runAction:[CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:animation restoreOriginalFrame:NO] ]];
id action = [CCMoveBy actionWithDuration:2 position:ccp(200,0)];
id action_back = [action reverse];
[sprite1 runAction: [CCRepeatForever actionWithAction:[CCSequence actions:action, action_back, nil]]];thanks.
fixed on r1651.
Since v1651 flip (flipX and flipY) behaves like scale *-1.
Is it just me, or has this issue reappeared in the intervening time? I'm running 0.99, and I'm seeing the exact issue described by shadaz at the top of the post. In summary:
Can anyone else confirm that they've had the same problem recently?
The desktop version of Zwoptex will have included leftTrim,topTrim.rightTrim, and bottomTrim data to allow the correct flipX/flipY calculations.
Alpha is close and Beta will be sometime in april.
