我创建了一个测验游戏,它实现了一个时间栏。在第一场比赛中没问题,但如果在比赛结束后,玩家点击“重启”,游戏就会正常进行,但时间栏会消失!
这里是我从GameOverLayer到Game的代码:
-(void) restart {
[[CCDirector sharedDirector] replaceScene:[HelloWorldLayer node]];
}
这里是创建新问题的功能
-(void)creaDomanda{
//bar
CCProgressFromTo *to1 = [CCProgressFromTo actionWithDuration:MaxTime from:100 to:0];
bar = [CCProgressTimer progressWithFile:@"barra.png"];
bar.type = kCCProgressTimerTypeHorizontalBarLR;
[bar setPosition:ccp(size.width - 250 , size.height - 18)];
int randomValue = (arc4random() % 4) + 1;
NSString *stringa = [NSString stringWithFormat:@"Domanda%i", randomValue];
dictionary = [plistData objectForKey:stringa];
domanda = [dictionary valueForKey:@"Titolo"];
labelDomanda = [CCLabelTTF labelWithString:domanda fontName:@"Marker Felt" fontSize:24];
labelDomanda.position = ccp( size.width /2 , 400 );
[self addChild: labelDomanda];
int rispostaEsatta = [[dictionary valueForKey:@"Soluzione"] intValue];
menu = [CCMenu menuWithItems:nil];
for (int i = 1; i<5;i++)
{
if(rispostaEsatta == i){
item = [CCMenuItemFont itemFromString:[dictionary valueForKey:
[NSString stringWithFormat:@"Risposta%i",i] ]
target:self selector:@selector(corretto)];
}else{
item = [CCMenuItemFont itemFromString:[dictionary valueForKey:
[NSString stringWithFormat:@"Risposta%i",i] ]
target:self selector:@selector(sbagliato)];
}
[menu addChild:item];
}
//[..]
[self addChild:menu];
[self addChild:bar];
[bar runAction:to1];
}
这里有一个正确/错误的方法(类似),毕竟,创建一个新问题:
-(void)sbagliato{
CCLOG(@"Sbagliato");
if (menu) [self removeChild:menu cleanup:YES];
if (labelDomanda) [self removeChild:labelDomanda cleanup:YES];
if (bar) [self removeChild:bar cleanup:YES];
labelRisultato = [CCLabelTTF labelWithString:@"Hai sbagliato!" fontName:@"Marker Felt" fontSize:24];
[labelRisultato setColor:ccc3(255, 1, 1)];
labelRisultato.position = ccp(size.width / 2, 280);
[self addChild:labelRisultato];
[self gameOver:2 punteggio:0];
// Richiamiamo il metodo per eliminare la label dopo 0,3 secondi
[self performSelector:@selector(eliminaLabel) withObject:nil afterDelay:0.5];
increment = increment - 20;
[pointLabel setString: [NSString stringWithFormat: @"Punti: %i", increment]];
// new question
[self performSelector:@selector(creaDomanda) withObject:nil afterDelay:0.5];
}
任何人都可以向我解释为什么当我重新启动时间棒时会破坏者? 谢谢
答案 0 :(得分:1)
我最好的猜测:
CCProgressFromTo操作仍在运行。由于它进展到0,因此CCProgressTimer最终不再显示它的任何部分。即使您对进度计时器运行另一个CCProgressFromTo操作,这可能会继续。
解决方案:确保在运行另一个CCProgressFromTo之前停止任何正在运行的CCProgressFromTo操作。
如果这不能解决问题,那么我认为需要通过将百分比设置回100来重置CCProgressTimer。
