Sprite 帧动画 Cocos2d 3.0

Sprite Frame Animation Cocos2d 3.0(Sprite 帧动画 Cocos2d 3.0)

问题描述

我一直在尝试制作动画精灵，它们有很多教程，但它们都是针对 Cocos2d 2.x 的.我的精灵表被命名为 fappbird.png 和 .plist 被命名为 fappbird.plist

I've been trying to make an animated sprite, they're are a lot of tutorials but they're all for Cocos2d 2.x. My sprite sheet is named flappbird.png and the .plist is named flappbird.plist

我有这段代码，但每次我启动场景时它都会崩溃，这是在我的 init 方法中

I have this code but every time i start the scene it just crashes, this is in my init method

// -----------------------------------------------------------------------

_player = [CCSprite spriteWithImageNamed:@"monster1.png"]; // comes from your .plist file
_player.position  = ccp(self.contentSize.width/28,self.contentSize.height/2);
_player.physicsBody = [CCPhysicsBody bodyWithRect:(CGRect){CGPointZero, _player.contentSize} cornerRadius:0]; // 1
_player.physicsBody.collisionGroup = @"playerGroup";
_player.physicsBody.type = CCPhysicsBodyTypeStatic;
CCSpriteBatchNode *batchNode = [CCSpriteBatchNode batchNodeWithFile:@"monster1.png"];
[batchNode addChild:_player];
[self addChild:batchNode];

NSMutableArray *animFrames = [NSMutableArray array];
for(int i = 1; i < 5; i++)
{
    CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"flapbird%d.png",i]];
    [animFrames addObject:frame];
}

CCAnimation *animation = [CCAnimation animationWithSpriteFrames:animFrames delay:0.2f];
[_player runAction:[CCActionRepeatForever actionWithAction:[CCActionAnimate actionWithAnimation:animation]]];

[_physicsWorld addChild:_player];

// -----------------------------------------------------------------------

推荐答案

Cocos2d 3.0 中使用 spritesheet 动画 sprite

Animate sprite with spritesheet in Cocos2d 3.0

确保在代码开头添加 #import "CCAnimation.h"

在 self.userInteractionEnabled = YES 之后添加精灵表；在初始化中

Also add the sprite sheet after the self.userInteractionEnabled = YES; in the init

[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"your.plist"];

不要在精灵所在的地方添加所有这些

No add all this where the sprite will be

//The sprite animation
NSMutableArray *walkAnimFrames = [NSMutableArray array];
for(int i = 1; i <= 7; ++i)
{
     [walkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: [NSString stringWithFormat:@"monster%d.png", i]]];
}
CCAnimation *walkAnim = [CCAnimation
                         animationWithSpriteFrames:walkAnimFrames delay:0.1f]; //Speed in which the frames will go at

//Adding png to sprite
monstertest = [CCSprite spriteWithImageNamed:@"monster1.png"];

//Positioning the sprite
monstertest.position  = ccp(self.contentSize.width/2,self.contentSize.height/2);

//Repeating the sprite animation
CCActionAnimate *animationAction = [CCActionAnimate actionWithAnimation:walkAnim];
CCActionRepeatForever *repeatingAnimation = [CCActionRepeatForever actionWithAction:animationAction];

//Animation continuously repeating
[monstertest runAction:repeatingAnimation];

//Adding the Sprite to the Scene
[self addChild:monstertest];
