cocos2d 掷骰子问题 急求一个dome事例最好了

Question

请各位大神看下 纠结了好几天 骰子的随机数和面数不一样 不知道是哪里出问题了 急求 解答

代码如下

-(void)shaizi{

CGSize winSize = [CCDirector sharedDirector].winSize;

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

CCSpriteBatchNode * spriteSheet1 = [CCSpriteBatchNode batchNodeWithFile:@"dice.png"];

[self addChild:spriteSheet1];

_rotate = [NSMutableArray array];

for (int i = 1; i <= 6; i ++)

{

[_rotate addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"%d.png",i]]];

}

CCAnimation *animation= [CCAnimation animationWithSpriteFrames:_rotate delay:0.1f];

self.shazi = [CCSprite spriteWithSpriteFrameName:@"1.png"];

_shazi.position = ccp(winSize.width/2, winSize.height/2);

self.rotateAction = [CCRepeat actionWithAction:[CCAnimate actionWithAnimation:animation] times:3];

[self.shazi runAction:_rotateAction];

[spriteSheet1 addChild:_shazi];

}

-(void) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{

NSLog(@"触摸开始时！");

[_shazi stopAllActions];

srand((unsigned)time(0)); //每次产生的随机数不变

//骰子结果

int result1 = (rand() % 5) +1 ; //产生1～6的

switch (result1) {

case 1:_shazi = [CCSprite spriteWithFile:@"1.png"];

faceNum = 1;

break;

case 2:_shazi = [CCSprite spriteWithFile:@"2.png"];

faceNum = 2;

break;

case 3:_shazi = [CCSprite spriteWithFile:@"3.png"];

faceNum = 3;

break;

case 4:_shazi = [CCSprite spriteWithFile:@"4.png"];

faceNum = 4;

break;

case 5:_shazi = [CCSprite spriteWithFile:@"5.png"];

faceNum = 5;

break;

case 6:_shazi = [CCSprite spriteWithFile:@"6.png"];

faceNum = 6;

break;

}

NSLog(@"%d",result1);

}

Answer 1

现在是面数不对

Answer 2

rand()%6才是随机数0~5，+1才对
