Question

我正在开发一款针对iOS的游戏，我想知道为什么倒计时不起作用。我希望在这个游戏中每个级别有一定数量的移动，我希望每次用户点击其中一个拼图时减去1个移动。

这是我设置的一些代码：

我在标题文件中设置了两个整数：int movesRemaining;和int moved;

显示移动量的SKLabelNode：

moves = [SKLabelNode labelNodeWithFontNamed:@"DIN Condensed"];
moves.position = CGPointMake(110, -15);
moves.text = [NSString stringWithFormat:@"MOVES %d", movesRemaining];
moves.fontSize = 25;
moves.zPosition = 2.0;
moves.fontColor = [SKColor whiteColor];

[menuBar addChild:moves];

计算得分的方法：

-(void)moves {
movesRemaining = 4;
movesRemaining = (movesRemaining - moved);

}

每次触摸拼图时告诉moveRemaining减1的代码移动：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];

if ([node.name isEqualToString:@"sq1"]) {
    [_BS1 removeFromParent];
    moved = 1;
}
if ([node.name isEqualToString:@"sq2"]) {
    [_BS2 removeFromParent];
    moved = 1;
}
if ([node.name isEqualToString:@"sq3"]) {
    [_BS3 removeFromParent];
    moved = 1;
}
if ([node.name isEqualToString:@"sq4"]) {
    [_BS4 removeFromParent];
    moved = 1;
}
if ([node.name isEqualToString:@"sq5"]) {
    [_BS5 removeFromParent];
    moved = 1;
}

我的问题是我哪里出错，每次点击拼图时它都不减1？每次用户触摸拼图时，如何正确地进行moveRemaining减1？

如果需要更多信息，请告诉我。

感谢。

Answer 1

将movesRemaining = 4;移至init方法。然后将[self moves];添加到-(void)touchesBegan的末尾。

Answer 2

在移动的方法中更改它以便声明move = moved - 1;然后，这将添加滚动效果

Answer 3

moves = [SKLabelNode labelNodeWithFontNamed:@"DIN Condensed"];
moves.position = CGPointMake(110, -15);
moves.text = [NSString stringWithFormat:@"MOVES %d", movesRemaining];
moves.fontSize = 25;
moves.zPosition = 2.0;
moves.fontColor = [SKColor whiteColor];
movesRemaining = 4; //Move initial movesRemaining value here.
[menuBar addChild:moves];


-(void)moves { //Subtract number of moves everytime the user moves.
movesRemaining = (movesRemaining - moved);
}

问题是它没有被更新。如何解决：

润色： - （void）touchesBegan：（NSSet *）触及withEvent：（UIEvent *）事件{

UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];

if ([node.name isEqualToString:@"sq1"]) {
    movesRemaining = movesRemaining - 1;
    [_BS1 removeFromParent];
}

取出initWithSize方法中的内容并将其添加到-(void)update:(CFTimeInterval)currentTime方法中：

if (!moves) {
moves = [SKLabelNode labelNodeWithFontNamed:@"DIN Condensed"];
moves.position = CGPointMake(110, -15);
moves.fontSize = 25;
moves.zPosition = 2.0;
moves.fontColor = [SKColor whiteColor];
[menuBar addChild:moves];

}

//得分 moves.text = [NSString stringWithFormat：@＆＃34; MOVES％d＆＃34;，moveRemaining];

这将修复您的代码。然后它会在每次点击时更新，就像你想要的那样。
