Question

My problem is that animation are not working properly during movements of sprite.
Below is the code which i’m using

- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {    

    [selSprite resumeSchedulerAndActions];
    CGPoint touchLocation = [self convertTouchToNodeSpace:touch];
    [self selectSpriteForTouch:touchLocation];   
    return TRUE;    
}

- (void)selectSpriteForTouch:(CGPoint)touchLocation  
{
 CCSprite * newSprite = nil;

    for (CCSprite *sprite in movableSprite) {
        if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) {            
            newSprite = sprite;
            break;
        }
    }    
    if (newSprite != selSprite) {
        [selSprite stopAllActions];

        selSprite = newSprite;

        _MoveableSpritetouch = TRUE;
    }

    if(_MoveableSpritetouch==TRUE)
    {
      movement=0;
CGRect selRect=CGRectMake((SpriteX)-20.0,(SpriteY)-20.0,40.0,40.0);
        if(CGRectContainsPoint(selRect, touchLocation))
        {  
            [selSprite stopAllActions];


        }
 if((selSprite==MarshallCar)&& (!(CGRectContainsPoint(selRect, touchLocation)))) 
        {
            movement=1;
            [self reorderChild:selSprite z:5];


            NSMutableArray *MarshallCarWalkAnimFrames = [NSMutableArray array];
            for(int i = MarshallCarTouchStartFrameIndex; i <= MarshallCarTouchEndFrameIndex; ++i) {
                [MarshallCarWalkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"mcar_move_%d.png", i]]];
            }
            MarshallCarWalkAnim = [CCAnimation animationWithFrames:MarshallCarWalkAnimFrames delay:MarshallCarTouchFrameDelay];
            walkMarshallCar = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:MarshallCarWalkAnim restoreOriginalFrame:NO]];


            [selSprite runAction:walkMarshallCar];
        }
}
}

- (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event {       


    if(gameState == TRUE){


        CGPoint point = [touch locationInView:[touch view]];
        point = [[CCDirector sharedDirector] convertToGL:point];
        if (moveDifference.x>0)
                    { 
                        selSprite.flipX = YES;
                    } 

                    else {
                        selSprite.flipX = NO;
                    } 
         [selSprite setPosition:point];


     }
  }

-(void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{   
    movement=0;
if(selSprite==MarshallCar)
    { 
        [selSprite setDisplayFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"mcar_idle.png"]];

    }
[selSprite pauseSchedulerAndActions];
}

The animation frames for movement are not playing every time during movements sometimes it plays or sometimes not. It plays properly when you touch and move your sprite for the first time but if touch another sprite and then again move the previous sprite the animations for movement won’t play.

Is anyone having any idea why this is happening?
Please tell me the proper code for removing this bug.
Thanks!!!

if((selSprite==MarshallCar)&& (!(CGRectContainsPoint(selRect, touchLocation)))) 
        {
            movement=1;
            [self reorderChild:selSprite z:5];


            NSMutableArray *MarshallCarWalkAnimFrames = [NSMutableArray array];
            for(int i = MarshallCarTouchStartFrameIndex; i <= MarshallCarTouchEndFrameIndex; ++i) {
                [MarshallCarWalkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"mcar_move_%d.png", i]]];
            }
            MarshallCarWalkAnim = [CCAnimation animationWithFrames:MarshallCarWalkAnimFrames delay:MarshallCarTouchFrameDelay];
            walkMarshallCar = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:MarshallCarWalkAnim restoreOriginalFrame:NO]];


            [selSprite runAction:walkMarshallCar];
        }

I have added [selSprite stopAllActions];
and it started working correctly because in the touch ended method i was pausing the actions
but not resuming them so when i touch the sprite for the second time it was not playing animation because the action was paused.
