Cocos2d Two animations for one sprite - animation

Question

I animate my character like that :
-(void) createHero
{
_batchNode = [CCSpriteBatchNode batchNodeWithFile:#"Snipe1.png"];
[self addChild:_batchNode];
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"Snipe1.plist"];
//gather list of frames
NSMutableArray *runAnimFrames = [NSMutableArray array];
for(int i = 1; i <= 7; ++i)
{
[runAnimFrames addObject:
[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
[NSString stringWithFormat:#"run000%d.png", i]]];
}
//create sprite and run the hero
self.hero = [CCSprite spriteWithSpriteFrameName:#"run0001.png"];
_hero.anchorPoint = CGPointZero;
_hero.position = self.heroRunningPosition;
//create the animation object
CCAnimation *runAnim = [CCAnimation animationWithFrames:runAnimFrames delay:1/30.0f];
self.runAction = [CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:runAnim restoreOriginalFrame:YES]];
[_hero runAction:_runAction];
[_batchNode addChild:_hero z:0];
}
This works fine an my character is running, but now i want a second animation when he jumps. At the moment i make it like that:
-(void)changeHeroImageDuringJump
{
[_hero setTextureRect:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:#"run0007.png"].rect];
}
But now i want a second plist with a second png, so i get a whole new animation when the character jumps. How can i implement that ?

Answer 1

In my case, i implemented an AnimatedSprite class that will handle this for me. This way, I add files like so:
NSDictionary* anims = [NSDictionary dictionaryWithObjectsAndKeys:
#"Animations/Character/idle_anim.plist", #"Idle",
#"Animations/Character/walk_anim.plist", #"Walk",
#"Animations/Character/run_anim.plist", #"Run", nil];
CCNode* myNode = [[AnimatedSprite alloc] initWithDictionary:anims
spriteFrameName: #"character_idle_01.png"
startingIndex:#"Idle"];
Changing the animation is as simple as:
[myNode setAnimation: #"Run"];
Heres my implementation This is the .h
#interface AnimatedSprite : CCSprite
{
NSMutableDictionary* _spriteAnimations;
CCAction* _currentAnimation;
NSString* _currentAnimationName;
bool _initialized;
}
- (id) initWithTextureName:(NSString*) textureName;
- (id) initWithArray: (NSArray*) animList spriteFrameName: (NSString*) startingSprite startingIndex: (int)startingIndex;
- (id) initWithDictionary:(NSDictionary *)anims spriteFrameName:(NSString *)startingSprite startingIndex:(NSString *)startingAnim;
- (void) addAnimation: (NSString*) animationName andFilename: (NSString*) plistAnim;
- (void) setAnimationIndex: (int) index;
- (void) setAnimation: (NSString*) animationName;
#end
And this is the .m
#import "AKHelpers.h"
#implementation AnimatedSprite
NSMutableDictionary* _spriteAnimations;
- (id) initWithTextureName:(NSString*) textureName
{
CCTexture2D* texture = [[CCTextureCache sharedTextureCache] addImage:textureName];
CCSpriteFrame* frame = [CCSpriteFrame frameWithTexture:texture rect: CGRectMake(0, 0, 1, 1)];
if ((self=[super initWithSpriteFrame:frame]))
{
_currentAnimationName = nil;
_currentAnimation = nil;
_spriteAnimations = [[NSMutableDictionary alloc] init ];
_initialized = true;
}
return self;
}
- (id) initWithArray: (NSArray*) animList spriteFrameName: (NSString*) startingSprite startingIndex: (int)startingIndex
{
_initialized = false;
_spriteAnimations = [[NSMutableDictionary alloc] init];
// Add animations as numbers from 0 to animList.count
int i = 0;
for (NSString* anim in animList)
{
[self addAnimation: [NSString stringWithFormat:#"%d", i] andFilename:anim];
i++;
}
if ((self = [super initWithSpriteFrameName:startingSprite]))
{
_currentAnimationName = nil;
_currentAnimation = nil;
[self setAnimationIndex: startingIndex];
_initialized = true;
}
return self;
}
- (id) initWithDictionary:(NSDictionary *)anims spriteFrameName:(NSString *)startingSprite startingIndex:(NSString *)startingAnim
{
_initialized = false;
_spriteAnimations = [[NSMutableDictionary alloc] init];//[[NSMutableArray alloc] init];
// Add animations
for (NSString* key in anims)
{
[self addAnimation: key andFilename: [anims objectForKey: key] ];
}
if ((self = [super initWithSpriteFrameName:startingSprite]))
{
_currentAnimationName = nil;
_currentAnimation = nil;
[self setAnimation: startingAnim];
_initialized = true;
}
return self;
}
- (void) dealloc
{
[_currentAnimationName release];
[_spriteAnimations release];
[super dealloc];
}
- (void) setAnimation: (NSString*) animationName
{
if (![_currentAnimationName isEqualToString:animationName])
{
[_currentAnimationName release];
_currentAnimationName = [animationName copy];
// Stop current animation
if (_currentAnimation != nil)
[self stopAction:_currentAnimation];
//[self stopAllActions];
// Apply animation
NSDictionary* clip = [_spriteAnimations objectForKey: animationName];
if (clip)
{
_currentAnimation = [AKHelpers actionForAnimationClip:clip];
if (_currentAnimation)
[self runAction:_currentAnimation];
}
else
{
_currentAnimation = nil;
}
}
}
- (void) setAnimationIndex: (int) index
{
[self setAnimation: [NSString stringWithFormat:#"%d", index]];
}
- (void) addAnimation: (NSString*) animationName andFilename: (NSString*) plistAnim
{
NSDictionary *clip = [AKHelpers animationClipFromPlist:plistAnim];
if (clip)
{
[_spriteAnimations setObject:clip forKey:animationName];
if (_initialized && [_spriteAnimations count] == 1)
{
[self setAnimation:animationName];
}
}
}
#end

Create two different animation actions for running and jumping. Run those actions on need basis.
