moving sprite animation - cocos2d-iphone

i have a cocos2d world, and a sprite/body that is moving fast .
when contact occur i am calling animation function.
The problem is , that when the animation is running in the current sprite position, the sprite was already gone to another place so animation is not in right place:
how would i run this animation function to follow my sprite ?
code:
-(void)animation:(NSString *)animation
{
NSLog(#"check:%#",animation);
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:[NSString stringWithFormat:#"%#.plist",animation]];
sprite = [CCSprite spriteWithSpriteFrameName:[NSString stringWithFormat:#"%#_00000.png",animation]]; //take the corrdinates of this picture from the plist
sprite.position=boy.position;
//sprite.position=ccp(160,175);
CCSpriteBatchNode *spriteSheet = [ CCSpriteBatchNode batchNodeWithFile:[NSString stringWithFormat:#"%#.png",animation]];
[spriteSheet addChild:sprite]; //add this coordinates from the spritesheet to the screen
[self addChild:spriteSheet];
NSString *Path = [[NSBundle mainBundle] bundlePath];
NSString *animPath = [Path stringByAppendingPathComponent: [NSString stringWithFormat:#"%#.plist", animation]];
NSDictionary *animSpriteCoords = [[NSDictionary alloc] initWithContentsOfFile: animPath];
NSDictionary *animFramesData = [animSpriteCoords objectForKey:#"frames"];
int b=0;
int a=0;
NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i < [animFramesData count]; i++)
{
a=a+1;
if(a==10)
{
b=b+1;
a=0;
}
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"%#_000%0i%1i.png",animation,b,a]]; //[NSString stringWithFormat:#"eye_blinking_0000%1d.png",i]
[animFrames addObject:frame];
}
//CCAnimation *dollAnimation = [CCAnimation animation];
CCAnimation* dollAnimation = [CCAnimation animationWithFrames:animFrames delay:0.1f];
//CCAnimation *dollAnimation = [CCAnimation animationWithName:#"dance" animationWithFrames:animFrames];
//[dollAnimation setDelay:0.1f];
CCAnimate * Action = [CCAnimate actionWithAnimation:dollAnimation];
id call=[CCCallFunc actionWithTarget:self selector:#selector(finishAnimation)];
id sequence=[CCSequence actions:Action,[CCHide action],call,nil];
[sprite runAction:sequence];
}
thnaks a lot.

CCFollow will have the animation sprite follow the boy sprite:
id follow = [CCFollow actionWithTarget:boy];
[sprite runAction:follow];
Alternative is to continuously update the animation sprite's position to that of the boy position (sprite.position = boy.position) in a scheduled update method.

How to create animation in cocos2d 3.0?

So I tried
self.walkAction = [CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:walkAnim]];
But then I discovered that CCRepeatForever has been renamed and CCAnimate removed. How can I replace this?
All code: http://pastebin.com/VnrtiCwb
CCRepeatForever was replaced with CCActionRepeatForever and CCAnimate with CCActionAnimate
try this code
CCSprite *sprite = [CCSprite spriteWithImageNamed:#"sv_anim_1.png"]; // comes from your .plist file
sprite.position = ccp( [[CCDirector sharedDirector] viewSize].width/2, [[CCDirector sharedDirector] viewSize].height/2 );
CCSpriteBatchNode *batchNode = [CCSpriteBatchNode batchNodeWithFile:#"scene1atlas.png"];
[batchNode addChild:sprite];
[self addChild:batchNode];
NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i < 5; i++)
{
//NSString *str=[NSString stringWithFormat:#"an1_anim%d.png",i];
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"an1_anim%d.png",i]];
[animFrames addObject:frame];
}
animation = [CCAnimation animationWithSpriteFrames:animFrames delay:0.2f];
[sprite runAction:[CCActionRepeatForever actionWithAction:[CCActionAnimate actionWithAnimation:animation]]];

How to run two animation at same time at same sprite?

In my game, I am running two animations using CCSpawn but it shows only one animation at a time. What is wrong here? Here is my code.
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"walkcycle.plist"] ;
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:#"walkcycle.png"];
[heroWorldLayer addChild:spriteSheet];
NSMutableArray *runFrames = [NSMutableArray array];
for(int i = 1; i <= 11; ++i) {
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"Run_Anim00%02d.png", i]];
[runFrames addObject:frame];
}
id runAnim = [CCAnimation animationWithFrames:runFrames delay:1.0/22.0];
id runAnimate = [CCAnimate actionWithAnimation:runAnim restoreOriginalFrame:NO];
// _runAction = [CCRepeatForever actionWithAction:runAnimate];
// [heroBodySprite runAction:_runAction];
NSMutableArray *poofFrames = [NSMutableArray array];
for(int i = 1; i <= 10; ++i) {
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"Poof00%02d.png", i]];
[poofFrames addObject:frame];
}
id poofAnim = [CCAnimation animationWithFrames:poofFrames delay:1.0/20.0];
id poofAnimate = [CCAnimate actionWithAnimation:poofAnim restoreOriginalFrame:NO];
// id poofAction = [CCRepeatForever actionWithAction:poofAnimate];
// [heroBodySprite runAction:poofAction];
[heroBodySprite runAction:[CCRepeatForever actionWithAction:[CCSpawn actions:runAnimate, poofAnimate, nil]]];
You basically want to display two different frames at the same time on the same sprite. That is just not possible, think about it. What kind of magic do you expect Cocos2d to do for you ? Some animations are just not made to be compatible with each other. It's like if you tried to move a sprite to the left and to the right at the same time, and were surprised it didn't work...

Cocos2d Sprite Sheet Not Animating

SpriteSheets are one thing I just can't get my head around. I'm looking for a very clear and easy to follow way to learn about them. I have read and studied up on them but still have problems.
I don't know why my code isn't working.
-(void) addPlayer {
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite *sprite = [CCSprite spriteWithSpriteFrameName:#"walk1.png"];
sprite.position = ccp(winSize.width/2, winSize.height/2);
CCSpriteBatchNode *batchNode = [CCSpriteBatchNode batchNodeWithFile:#"player-walk.png"];
[batchNode addChild:sprite];
[self addChild:batchNode z:350];
NSMutableArray *frames = [NSMutableArray array];
for(int i = 1; i <= 4; ++i) {
[frames addObject:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"walk%d.png", i]]];
}
CCAnimation *anim = [CCAnimation animation];
CCAnimate *animate = [CCAnimate actionWithAnimation:anim];
CCRepeatForever *repeat = [CCRepeatForever actionWithAction:animate];
[self runAction:repeat];
}
Why is my player not animating?
Spritesheet is just a convenient way to store textures.
Your CCAnimation object has no frames. You gather an array of frames, but you never use it. Change your
CCAnimation *anim = [CCAnimation animation];
line to
CCAnimation *anim = [CCAnimation animationWithFrames:frames delay:0.2f];
If you want to animate a sprite, you have to run animating action on this sprite. Use [sprite runAction:repeat] instead of [self runAction:repeat];.

animate a moving sprite

i know how to animate a sprite using cocos2d , with a spritesheet and plist .
i have a world, and the sprite can move in this world when forces applied .
i need to animate that sprite, while is moving , lets say he falls down, so his eyes should be blinking while he falls ,or move etc..
my code to animate now is this, when i insert a new sprite, but i need to apply it on a specific sprite ,not on a specific place ...
-(void)animation:(NSString *)animation
{
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:[NSString stringWithFormat:#"%#.plist",animation]];
sprite = [CCSprite spriteWithSpriteFrameName:[NSString stringWithFormat:#"%#_00000.png",animation]]; //take the corrdinates of this picture from the plist
//sprite.position=ccp(240,160);
//sprite.position=ccp(160,175);
CCSpriteBatchNode *spriteSheet = [ CCSpriteBatchNode batchNodeWithFile:[NSString stringWithFormat:#"%#.png",animation]];
[spriteSheet addChild:sprite]; //add this coordinates from the spritesheet to the screen
[self addChild:spriteSheet];
NSString *Path = [[NSBundle mainBundle] bundlePath];
NSString *animPath = [Path stringByAppendingPathComponent: [NSString stringWithFormat:#"%#.plist", animation]];
NSDictionary *animSpriteCoords = [[NSDictionary alloc] initWithContentsOfFile: animPath];
NSDictionary *animFramesData = [animSpriteCoords objectForKey:#"frames"];
int b=0;
int a=0;
NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i < [animFramesData count]; i++)
{
a=a+1;
if(a==10)
{
b=b+1;
a=0;
}
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"%#_000%0i%1i.png",animation,b,a]]; //[NSString stringWithFormat:#"eye_blinking_0000%1d.png",i]
[animFrames addObject:frame];
}
CCAnimate *Action ;
CCAnimation* dollAnimation = [CCAnimation animationWithFrames:animFrames delay:0.1f];
Action = [CCAnimate actionWithAnimation:dollAnimation];
id call=[CCCallFunc actionWithTarget:self selector:#selector(finishAnimation)];
id sequence=[CCSequence actions:Action,[CCHide action],call,nil];
[sprite runAction:sequence];
}
You have to change the animation to walk when it start to move and change when stop in [sprite runAction:sequence];

Box2D body with animating sprite sheet plist

I have created an animating sprite using CCSpriteBatchNode and CCSprite. I use plist to get frames. Here is the code I put it in init().
//================== making animating sprite
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: #"framelist.plist"];
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode
batchNodeWithFile:#"frames.png"];
[self addChild:spriteSheet];
NSMutableArray *walkAnimFrames = [NSMutableArray array];
for(int i = 1; i <= 2; ++i) {
[walkAnimFrames addObject:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
[NSString stringWithFormat:#"frame%d.png", i]]];
}
CCAnimation *walkAnim = [CCAnimation
animationWithFrames:walkAnimFrames delay:0.1f];
//_frameSprite is CC Sprite
_frameSprite = [CCSprite spriteWithBatchNode:spriteSheet
rect:CGRectMake(0,0,48,48)];
_frameSprite.position = ccp(winSize.width + 60, winSize.height/2);
_flyAction = [CCRepeatForever actionWithAction:
[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO]];
[_frameSprite runAction:_flyAction];
[spriteSheet addChild:_frameSprite];
Once the sprite is ready and running on screen I created b2BodyDef and assign b2Body (i.e. frameBodyDef, frameBody) my sprite as shown below.
b2BodyDef frameBodyDef;
frameBodyDef.type = b2_staticBody;
frameBodyDef.position.Set(160/PTM_RATIO, 200/PTM_RATIO);
frameBodyDef.userData = _frameSprite;
frameBody = _world->CreateBody(&frameBodyDef);
After creating the body, when build and ran, the program crashes at line
frameBody = _world->CreateBody(&frameBodyDef);
Saying BAD ACCESS.
Please kindly help me out in this, why the animating sprite cannot be added to the body???
Thank you.
Here is the solution I figure it out.
If you make sprite sheet from plist and want your animation sheet to add to the body make sure first add your sprite object to the body then add the sprite to the sheet.
here is the right code
//================== making animating sprite
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: #"framelist.plist"];
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode
batchNodeWithFile:#"frames.png"];
[self addChild:spriteSheet];
NSMutableArray *walkAnimFrames = [NSMutableArray array];
for(int i = 1; i <= 2; ++i) {
[walkAnimFrames addObject:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
[NSString stringWithFormat:#"frame%d.png", i]]];
}
CCAnimation *walkAnim = [CCAnimation
animationWithFrames:walkAnimFrames delay:0.1f];
//_frameSprite is CC Sprite
_frameSprite = [CCSprite spriteWithBatchNode:spriteSheet
rect:CGRectMake(0,0,48,48)];
_frameSprite.position = ccp(winSize.width + 60, winSize.height/2);
_flyAction = [CCRepeatForever actionWithAction:
[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO]];
[_frameSprite runAction:_flyAction];
b2BodyDef frameBodyDef;
frameBodyDef.type = b2_staticBody;
frameBodyDef.position.Set(160/PTM_RATIO, 200/PTM_RATIO);
frameBodyDef.userData = _frameSprite; //================first add the sprite to body
frameBody = _world->CreateBody(&frameBodyDef);
[spriteSheet addChild:_frameSprite]; //======second add sprite to the sheet
