I am trying to play a sequence of PNGs in my application using the following code:
animatedSprite = [CCSprite spriteWithFile:#"Anim_1.png"];
animatedSprite.position = ccp( 512, 435 );
[self animatedSprite z:5];
NSArray *animFrames = [[NSArray alloc] initWithObjects:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:#"Anim_1.png"],
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:#"Anim_2.png"], nil];
spriteAnim = [CCAnimation animationWithSpriteFrames:animFrames delay:1.0f/24.0f];
id animAction = [CCAnimate actionWithAnimation:spriteAnim];
[spriteAnim runAction:animAction];
the 'animatedSprite' is added correctly but the animation doesn't play. What am I missing here?
I am using Cocos2d 2.0, xcode 4.5
You should run the action on the sprite, not the animation.
[animatedSprite runAction:animAction];

According to this tutorial PVR images seem to be the best format for iOS sprites. However after creating a sprite sheet with Texturepacker and exporting out to this format I cannot get the animation to work in cocos2d.
According to the documentation here I should be using
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"LuckyCompiled.plist"];
But neither the tutorial nor the documentation explain how to do animation, except for this. Which is what the code below is based on.
But this only places the base image onto the layer and does not animate.
CCSprite *sprite = [[CCSprite alloc]init];
sprite.position = ccp(player.contentSize.width/2+40, winSize.height/2+40);
// Obtain the shared instance of the cache
CCSpriteFrameCache *cache = [CCSpriteFrameCache sharedSpriteFrameCache];
// load the frames
[cache addSpriteFramesWithFile:#"LuckyCompiled.plist"];
// It loads the frame named "frame1.png".
// IMPORTANT: It doesn't load the image "frame1.png". "frama1.png" is a just the name of the frame
CCSpriteFrame *frame = [cache spriteFrameByName:#"lucky1.png"];
[sprite setDisplayFrame:frame];
[self addChild:sprite];
NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i < 10; i++) {
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"lucky%d.png",i]];
[animFrames addObject:frame];
}
NSLog(#"animaframes %#",animFrames);
CCAnimation *animation = [CCAnimation animationWithSpriteFrames:[NSArray arrayWithArray:animFrames]];
[sprite runAction:[CCAnimate actionWithAnimation:animation]];
Answer:
Needed to have a delay otherwise animation wasnt noticeable
[CCAnimation animationWithSpriteFrames:[NSArray arrayWithArray:animFrames]];
should have been (also no need to make is nsarray, mutable is fine)
[CCAnimation animationWithSpriteFrames:frames delay:0.1f];
Here is the code that I tried, it works fine.
CCSpriteFrameCache *frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
[frameCache addSpriteFramesWithFile:#"walkFrames.plist"];
player = [CCSprite spriteWithSpriteFrameName:#"f1.png"];
NSMutableArray *frames = [NSMutableArray arrayWithCapacity:8];
for (int i = 1; i < 9; i++) {
NSString *file = [NSString stringWithFormat:#"f%d.png", i];
CCSpriteFrame *frame = [frameCache spriteFrameByName:file];
[frames addObject:frame];
}
CCAnimation *walkAnim =[CCAnimation animationWithSpriteFrames:frames delay:0.1f];
CCAnimate *animate = [CCAnimate actionWithAnimation:walkAnim];
CCRepeatForever *rep = [CCRepeatForever actionWithAction:animate];
player.position = ccp(23, 285);
[player runAction:rep];
[self addChild:player];
Hi I'm making a game for iphone and when the sprite moves I want it to change image between 3 images so it looks like it's running.
I'm using cocos2d right now and I'm pretty new to cocos2d. I know how to do this with cocoa but that doesn't work with cocos2d.
So my question is how do I change the sprite image between 3, images and I want to loop it while I'm holding my finger on a position on the screen?
Thanks in advance.
This is a pretty loaded question for being new to cocos2d.
I would work on the infinite animation first. Get that working and then work on pausing, resuming, and flipping the animation.
You can set up the animation in the same method that you are adding the sprite.
NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i <= 3; i++) {
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"Sprite-%d.png",i]];
[animFrames addObject:frame];
}
CCAnimation *animation = [CCAnimation animationWithName:#"run" delay:0.1f frames:animFrames];
[mySprite runAction:[CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:animation restoreOriginalFrame:NO]]];
If you are unfamiliar with sprite sheets, there are plenty of free resources for creating a sprite sheet and plist (TexturePacker has a nice interface)
If you have trouble getting this to work, Ray Wenderlich has good tutorials. If you get this far here are some pointers for pausing, resuming, and flipping the animation
For pausing or resuming
[mySprite pauseSchedulerAndActions];
[mySprite resumeSchedulerAndActions];
Flip the animation whenever the touch directions switches horizontal directions
mySprite.flipX = YES;
mySprite.flipX = NO;
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"animations/grossini.plist"];
CCSprite *sprite = [CCSprite spriteWithSpriteFrameName:#"grossini_dance_01.png"];
sprite.position = ccp( 100, 100);
CCSpriteSheet *spritesheet = [CCSpriteSheet spriteSheetWithFile:#"animations/grossini.png"];
[spritesheet addChild:sprite];
[self addChild:spritesheet];
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" frames:animFrames];
// 14 frames * 0.2sec = 2,8 seconds
[sprite runAction:[CCRepeatForever actionWithAction: [CCAnimate actionWithDuration:2.8f animation:animation restoreOriginalFrame:NO] ]];
I'm developing an app using cocos2d and box2d phisycs. I whant to make my sprite animate on moving. I made a *.plist and *.png files in Zwoptex, and added them to my project. Now, I'm trying to create a sprite:
[[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:#"SquirrelAnimation.plist"];
node = [CCSpriteBatchNode batchNodeWithFile:#"SquirrelAnimation.png" capacity:100];
spriteTexture = [node texture];
b2BodyDef bodyDef;
bodyDef.type = bodyType;
CGSize size = [CCDirector sharedDirector].winSize;
CGPoint point = ccp(size.width / 2, size.height / 2);
bodyDef.position.Set(point.x / PTM_RATIO, point.y / PTM_RATIO);
body = world->CreateBody(&bodyDef);
sprite = [PhysicsSprite spriteWithTexture:spriteTexture];
[sprite setPhysicsBody:body];
[node addChild:sprite];
but this code makes one sprite with all frames to node. What am I doing wrong?
Extract frame like this...
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"spritesheet.plist"];
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:#"spritesheet.png"];
[self addChild:spriteSheet];
NSMutableArray *frames = [[[NSMutableArray alloc]init]retain];
for(int i = 1; i <= numberFrames; i++) {
[frames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"%#0%d.png", file_name, i]]];
}
// Animation object with 0.04 seconds between each frame (~30fps)
CCAnimation *anim = [CCAnimation animationWithFrames:frames delay:0.04f];
if(self.sprite){
// Animate the sprite
[self.sprite runAction:[CCAnimate actionWithAnimation:anim restoreOriginalFrame:NO]];
}
Basically, I'm trying to animate a sprite. When moving right I want one animation to play, and when moving left another to play. Here's my code-- nothing is happening at all, the sprite is merely shown on the screen.
-(void)moveLeft{
[sprite stopActionByTag:0];
NSMutableArray *spriteFrames2 = [NSMutableArray array];
CCSpriteFrame *frame4 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesLeft10.png"];
CCSpriteFrame *frame5 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesLeft11.png"];
CCSpriteFrame *frame6 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesLeft12.png"];
[spriteFrames2 addObjectsFromArray:[NSArray arrayWithObjects:frame4,frame5,frame4,frame6, nil]];
CCAnimation *anim = [CCAnimation animationWithFrames:spriteFrames2 delay:0.15f];
CCAnimate *animate = [CCAnimate actionWithAnimation:anim];
CCRepeatForever *repeat = [CCRepeatForever actionWithAction:animate];
repeat.tag = 1;
[sprite runAction:repeat];
id moveToLeft = [CCMoveTo actionWithDuration:3.0 position:CGPointMake(0, sprite.position.y)];
[sprite runAction:moveToLeft];
}
-(void)moveRight{
[sprite stopActionByTag:1];
CGSize winSize = [[CCDirector sharedDirector]winSize];
NSMutableArray *spriteFrames = [NSMutableArray array];
CCSpriteFrame *frame1 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesRight6.png"];
CCSpriteFrame *frame2 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesRight4.png"];
CCSpriteFrame *frame3 = [[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:#"KnightSpritesRight5.png"];
[spriteFrames addObjectsFromArray:[NSArray arrayWithObjects:frame1,frame2,frame1,frame3, nil]];
CCAnimation* anim = [CCAnimation animationWithFrames:spriteFrames delay:0.15f];
CCAnimate* animate = [CCAnimate actionWithAnimation:anim];
CCRepeatForever *repeat = [CCRepeatForever actionWithAction:animate];
repeat.tag = 0;
[sprite runAction:repeat];
id moveToRight = [CCMoveTo actionWithDuration:3.0 position:CGPointMake(winSize.width, sprite.position.y)];
[sprite runAction:moveToRight];
}
-(id) init
{
if( (self=[super init])) {
[[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:#"KnightImages2.plist"];
sprite = [CCSprite spriteWithSpriteFrameName:#"KnightSpritesRight6.png"];
sprite.position = ccp(240, 180);
[self addChild:sprite];
id actionSequence = [CCSequence actions:[CCCallFunc actionWithTarget:self selector:#selector(moveRight)],[CCCallFunc actionWithTarget:self selector:#selector(moveLeft)], nil];
CCRepeatForever *repeatForever = [CCRepeatForever actionWithAction:actionSequence];
[sprite runAction:repeatForever];
}
return self;
}
The way you've set this up is that the following happens, frame by frame:
Frame 1
execute moveRight
execute moveLeft
Frame 2
execute moveRight
execute moveLeft
Ad infinitum.
Since you're starting the animation all over every time you call moveRight or moveLeft, nothing really happens. You need to wait some time before running another animation for it to actually play. You can use the CCDelayTime action for this:
id actionSequence = [CCSequence actions:
[CCCallFunc actionWithTarget:self selector:#selector(moveRight)],
[CCDelayTime actionWithDuration:2],
[CCCallFunc actionWithTarget:self selector:#selector(moveLeft)],
[CCDelayTime actionWithDuration:2],
nil];
I am trying to make a sprite animate in cocos2D. I believe I have the animation set up, but how do I draw the animating sprite onto the screen? Here is what I have:
id anim = [[[CCAnimation alloc] initWithName:#"char_walking" delay:1/12.0] autorelease];
[anim addFrame:#"run2.png"];
[anim addFrame:#"run1.png"];
[anim addFrame:#"run3.png"];
[anim addFrame:#"run4.png"];
[anim addFrame:#"run3.png"];
[anim addFrame:#"run1.png"];
id myAction = [CCAnimate actionWithAnimation:anim];
id repeating = [CCRepeatForever actionWithAction:myAction];
[character do:repeating];
character = [CCSprite spriteWithSpriteFrame:anim];
character.position = ccp(160, 240);
[self addChild:character];
Thanks in advance,
John
Maybe it was just a cut-and-paste error, but it looks like you're telling the sprite to repeat the animation BEFORE you create it, so the character sprite you are adding to the node never gets the CCAnimate action sent to it.
You're not adding spriteFrames as the addFrame method requires.
with this line:
[character do:repeating];
maybe you're looking for [character runAction:repeating];
character = [CCSprite
spriteWithSpriteFrame:anim];
Here, anim is not a spriteFrame, it's a CCanimation.
basically, you have a few problems.
you could try something like this using zwoptex to create your .plist file:
CCSpriteFrameCache *cache = [CCSpriteFrameCache sharedSpriteFrameCache];
[cache addSpriteFramesWithFile:#"runImages.plist"];
CCSprite *startingImage = [CCSprite spriteWithSpriteFrameName:#"run1.png"];
[self addChild:startingImage];
//create your sprite frames
NSArray *animFrames = [[NSArray alloc] initWithCapacity:6];
[animFrames addFrame:[cache spriteFrameByName:#"run2.png"]];
[animFrames addFrame:[cache spriteFrameByName:#"run1.png"]];
[animFrames addFrame:[cache spriteFrameByName:#"run3.png"]];
[animFrames addFrame:[cache spriteFrameByName:#"run4.png"]];
[animFrames addFrame:[cache spriteFrameByName:#"run3.png"]];
[animFrames addFrame:[cache spriteFrameByName:#"run1.png"]];
//run the animation
CCAnimation *animation = [CCAnimation animationWithName:#"char_walking" delay:1/12.0 frames:animFrames];
id anim = [CCAnimate actionWithAnimation:animation restoreOriginalFrame:NO];
[startingImage runAction:anim];
