[Solved] Guys, I found another tool on Mac app store named Plist Extractor that can help me do this. Thank you guys so so much!
I found this project on GitHub. It is a utility to unpack cocos2D sprite sheet used by cocos2d engine. After try reading and debugging this project, I cannot found any errors but it does not work as I expect. Particularly, it always generate blank images from sprite frame and save it to disk. So anyone please help me debug it. I also attach a sprite sheet for you guys to test.
Link to sprite sheet.
Try This SpriteSheetUnPacker its working with your sprite sheet.
Try this
#import "ExtractImagesFromTP.h"
[ExtractImagesFromTP createImagesFromTPPlist:#"sprite_sheet.plist"];
ExtractImagesFromTP Class
.h
#interface ExtractImagesFromTP : NSObject
+ (void)createImagesFromTPPlist:(NSString *)plist;
#end
.m
#implementation ExtractImagesFromTP
+ (NSDictionary *)getAllFrameFromPlist:(NSString *)plistFile
{
NSString *path = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent: plistFile];
NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfFile:path];
return [dictionary objectForKey: #"frames"];
}
+ (void)createPngFromSprite:(CCSprite *)sprite fileName:(NSString *)fileName
{
sprite.position = ccpMult(ccpFromSize(sprite.contentSize), 0.5);
[CCDirector sharedDirector].nextDeltaTimeZero = YES;
CCRenderTexture* render = [CCRenderTexture renderTextureWithWidth:sprite.contentSize.width height:sprite.contentSize.height];
[render begin];
[sprite visit];
[render end];
NSLog(#"Texture Name: %#", fileName);
[render saveToFile:fileName format:CCRenderTextureImageFormatPNG];
}
+ (void)createImagesFromTPPlist:(NSString *)plist
{
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: plist];
NSDictionary *frameNames = [self getAllFrameFromPlist: plist];
for (NSString *frameName in frameNames)
{
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:frameName];
CCSprite *sprite = [CCSprite spriteWithSpriteFrame: frame];
[self createPngFromSprite:sprite fileName:frameName];
}
}

So after taking a little break after being very frustrated for months on end with this issue, I am now back and attempting to solve my issue once and for all.
I’m not going to post code, because the code I have is messy and patchy and is from countless points of view.
My issue is this:
I have a sprite, and his information is stored in a class called player.m. I have a game level, and it is stored in GameLevelLayer.m
I have player.m store velocity, direction, and all the information about the character, and then I have the GameLevelLayer.m implement, move, use bounds to check collisions, etc.
I now want to make the character move using a spritesheet (I know how to do spritesheeting, I just don’t know how to do it while working with two different classes)
My question is, do I create the batchnodes and spritesheet information (CCBatchnodes, caches, etc) and all of the actions and everything in player.m, and then run them in GameLevelLayer.m? Or do I create all that in GameLevelLayer.m
I really need some help here because I’ve been stuck on this for months
EDIT:
Here is where I am, thanks to a suggestion from a community member.
This is my entire player.m (Long story short, I define everything about the player 'you might just want to pay attention to the init, because that seems to be the problem. The other stuff is my physics engine')
#import "Player.h"
#import "SimpleAudioEngine.h"
#import "GameLevelLayer.h"

-(id)initWithTexture:(CCTexture2D *)texture{
if (self = [super init]) {
self.velocity = ccp(0.0, 0.0);
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: #"BankerSpriteSheet_default.plist"];
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:#"BankerSpriteSheet_default.png"];
[self addChild:spriteSheet];
NSMutableArray *walkAnimFrames = [NSMutableArray array];
for(int i = 1; i <=6; ++i) {

}
}
return self;
}
-(void)update:(ccTime)dt {

CGPoint jumpForce = ccp(0.0, 310.0);

}
}
} else if (!self.mightAsWellJump && self.velocity.y > jumpCutoff) {
self.velocity = ccp(self.velocity.x, jumpCutoff);
}
CGPoint gravity = ccp(0.0, -450.0);

CGPoint stepVelocity = ccpMult(self.velocity, dt);
if (!self.isGoingLeft) {
self.desiredPosition = ccpAdd(self.position, stepVelocity);
}else{
self.desiredPosition = ccp(self.position.x-stepVelocity.x, self.position.y+stepVelocity.y);
}
}
-(CGRect)collisionBoundingBox {
CGRect collisionBox = CGRectInset(self.boundingBox, 3, 0);
//CGRect collisionBox = self.boundingBox;
//collisionBox = CGRectOffset(collisionBox, 0, -2);
CGPoint diff = ccpSub(self.desiredPosition, self.position);
CGRect returnBoundingBox = CGRectOffset(collisionBox, diff.x, diff.y);
return returnBoundingBox;
}
#end
So now the issue is, how do i get the player to appear in the game like a normal sprite, and then how do I run the animations when the player begins to move forward
Your game architecture is very good! Keep player properties on player and use GameLayer only to send player actions is the best approach.
If your Player Class extends from CCSprite, put everithing related to player in your Player Class: Run animations on it, load the cache on player constructor (use the CCSprite initWithTexture:rect:rotated: or a custom autorelease constructor, like a +(id)player ).
Then, in your GameLevelLayer you will need a CCSpriteBatchNode to add your player to it. You can use this batch node to add other objects that use same spritesheet.
EDIT:
Reviewing your code, your initWithTexture is wrong. The correct is to call [super initWithTexture:]:
-(id)initWithTexture:(CCTexture2D *)texture{
if (self = [super initWithTexture:texture]) {
Then, in your GameLevelLayer, create your player and add it to a CCSpriteBatchNode:
// *** In GameLevelLayer.m ***
// Create player
Player *player = [Player spriteWithFile:#"player.png"];
// Create batch node
CCSpriteBatchNode *batchNode = [CCSpriteBatchNode batchNodeWithTexture:player.texture];
// Add batch node as child
[self addChild:batchNode];
// Add player as batch node's child
[batchNode addChild:player];
// Set player position
player.position = ccp(100,100);
Your GameLevelLayer needs to do only this to create your Player. And when it detects user input, call methods like "jump", "moveRight", "moveLeft" in your player. Also detect collisions and send actions to player like "die", "getSpecialItem".
// *** In GameLevelLayer.m ***
[player jump];
[player die];
So, your player needs to handle these methods and performs its own logic to do the actions:
// *** In Player.m ***
- (void)moveRight
{
self.position = ccpAdd(self.position, ccp(10,0));
}
First, let's be clear on two things. My English is terrible and I'm pretty new in cocos2d. So sorry and sorry again. :D Now for my question.
I have declared these in a .m (Its a CCscene):
//A mutable array global to my class
NSMutableArray *arrayBoutons;
//I use this array like this :
LettreBleue *lettre1 = nil;
lettre1 = [LettreBleue construireObjLettre];
lettre1.position = ccp(80,370);
[self addChild:lettre1];
[arrayBoutons addObject:lettre1];
//The method to register the touch
-(void) registerWithTouchDispatcher
{
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:kCCMenuTouchPriority swallowsTouches:NO];
}
// The classic TouchBegan in which Im trying to access the value Valeur
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
// test!
NSLog(#"Debut test ccTouchBegan4");
int cptLettres = 0;
do {
LettreBleue *unBoutontest=[arrayBoutons objectAtIndex: cptLettres];
NSLog(unBoutontest.Valeur);
cptLettres = cptLettres+1;
} while (cptLettres < 16);
The problem is my arrayBoutons doesn't seem to keep my data in my NsMutableArray.
Have you initialized the NSMutableArray, perhaps in an init method? You need to call something like:
arrayBoutons = [[NSMutableArray alloc] init];
Then, you need to release it in your dealloc method:
[arrayBoutons release];
I am trying to preload an animation in the init method of my layer. I then call the animation if the screen is touched. The app crashes with no error message as soon as I touch the screen and seems it is to do with calling the preloaded animation. I would like to do it this way as it seems expensive to create the animation every time the screen is touched - which does seems to work though. Any tips greatly appreciated.
Sample Code:
In my header:
#interface Test : CCLayer {
NSMutableArray *wake;
CCSprite* ani;
CCAnimate *animate;
}
#end
In my implementation:
-(id) init {
if( (self=[super init])) {
// enable touches
self.isTouchEnabled = YES;
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"ani.plist" texture:[[CCTexture2D alloc] initWithImage:[UIImage imageNamed:#"ani.png"]]];
ani = [CCSprite spriteWithSpriteFrameName:#"ani1.png"]; //comes from .plist file
ani.anchorPoint=ccp(0,0);
ani.position = ccp(700,65);
[self addChild:ani z:30];
wake = [NSMutableArray array];
for(int i = 1; i <= 4; i++) {
[wake addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:#"ani%d.png",i]]];
}
animate = [CCAnimate actionWithAnimation:[CCAnimation animationWithFrames:wake delay:1.0f] restoreOriginalFrame:FALSE];
}
return self;
}
Handling the touch:
- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
// run the animation
[ani runAction:animate];
}
Animations in Cocos2d are not designed to be reused. You need to create a new one every time.
Problem solved by creating properties for the array and animation on the class using nonatomic,retain.
You only need to retain the animation but the array can be local.
self.myAnimation = [[CCAnimation animationWithFrames:myAniFramesArray delay:0.1f] retain];
Remember to make the property nonatomic, retain as stated by Chev and to release any objects you retain in the appropriate dealloc method.
I'm trying to make a effect using the CCBitmapFontAtlas, here is what I want:
The string say "ABCDEFG" being dispayed one by one, each one won't be displayed
until the one before is completely displayed.
And here is what I tried:
-(id) init
{
if( (self=[super init] )) {
label = [CCBitmapFontAtlas bitmapFontAtlasWithString:#"ABC" fntFile:#"bitmapFontTest.fnt"];
[self addChild:label];
CGSize s = [[CCDirector sharedDirector] winSize];
label.position = ccp(s.width/2, s.height/2);
label.anchorPoint = ccp(0.5f, 0.5f);
label.visible = NO; //hide it first
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
}
return self;
}
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
CCSprite AChar = (CCSprite) [label getChildByTag:0];
CCSprite BChar = (CCSprite) [label getChildByTag:1];
CCSprite CChar = (CCSprite) [label getChildByTag:2];
id fade_in = [CCFadeIn actionWithDuration:3];
label.visible = YES;
[AChar runAction:fade_in];
[BChar runAction:fade_in];
[CChar runAction:fade_in];
return YES;
}
The effect is the "ABC" will fade in once I touched the screen, then I tried to use the
CallFuncND to call the next string to fade in while the current string is displayed.
But this seems to make things very complex.
Is there a easier way to get this effect done?
Any suggestion will be appreciate.
I feel like you are going in the right direction with this one. You could have each letter be a separate sprite and store them in an array and then run them each one by one.
The call function can be started by:
[self displayNextSprite:spriteArray nextIndex:0];
And the function is:
// Warning, This assumes you are not passing it an empty array, you may want to put in a check for that
-(void)displayNextSprite:(NSMutableArray*)spriteArray nextIndex:(NSUInteger)nextIndex
{
CCSprite *nextSprite = [spriteArray objectAtIndex:nextIndex];
id action1 = [CCFadeIn actionWithDuration:3];
// or = [CCPropertyAction actionWithDuration:3 key:#"opacity" from:0 to:255];
// The last letter
if(nextIndex == ([spriteArray count] - 1))
{
[nextSprite runAction:action1];
}
else // continue to the next letter
{
id callFunc = [CCCallFunc actionWithTarget:self selector:#selector(displayNextSprite:spriteArray nextIndex:nextIndex+1)];
id sequence = [CCSequence actionOne:action1 two:callFunc];
[nextSprite runAction:sequence];
}
}
