Ios 精灵套件游戏没有检测到两个同时触碰

我正在开发一款精灵套件游戏，需要对屏幕左侧或右侧的触摸做出反应。我在另一个问题中找到了这个解决方案：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint touchLocation = [touch locationInNode:self];

if (touchLocation.x < self.size.width / 2.0f) {
    touching = YES;
}

if (touchLocation.x > self.size.width / 2.0f) {
    [self drawRocket];
}

}

以及

-（void）touchesbeated:（NSSet*）toucheevent:（UIEvent*）event{
UITouch*touch=[触摸任何对象]；
CGPoint touchLocation=[触摸位置Innode:self]；
用于（UITouch*触摸屏）{
如果（触摸位置.xself.size.width/2.0f）{
如果（！[rocketFlame父级]）{
[自燃火箭]；
}
}
}

}

我仍然有同样的问题。

在初始化方法中添加以下行 self.view.multipleTouchEnabled=是

for (UITouch *touch in touches) {

CGPoint touchLocation = [touch locationInNode:self];
if (touchLocation.x < self.size.width / 2.0f) {
    touching = YES;
}

if (touchLocation.x > self.size.width / 2.0f) {
    [self drawRocket];
}
}

用于（UITouch*触摸屏）{
CGPoint touchLocation=[触摸位置Innode:self]；
如果（触摸位置.xself.size.width/2.0f）{
[自拔火箭]；
}
}

使用鼠标和键盘模拟多点触控手势

您正在定义一个局部变量，该变量隐藏用于在触控事件上循环的变量。请参阅下面代码中的注释

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UITouch *touch in touches) {

        // The following statement is causing the issue. Delete it.
        //UITouch *touch = [touches anyObject];

        CGPoint touchLocation = [touch locationInNode:self];

        if (touchLocation.x < self.size.width / 2.0f) {
            touching = YES;
        }

        if (touchLocation.x > self.size.width / 2.0f) {
            if (![rocketFlame parent]) {
                [self fireRocket];
            }
        }
    }
}

-（void）touchesbeated:（NSSet*）toucheevent:（UIEvent*）event{
用于（UITouch*触摸屏）{
//以下语句导致问题。请删除它。
//UITouch*touch=[触摸任何对象]；
CGPoint touchLocation=[触摸位置Innode:self]；
如果（触摸位置.xself.size.width/2.0f）{
如果（！[rocketFlame父级]）{
[自燃火箭]；
}
}
}
}

您需要处理所有触摸，而不仅仅是[触摸任何对象]。。ie在每次触摸上枚举：对于（UITouch*touch in Touchs）{..}@LearnCos2D请用代码示例回答，我不确定要更改哪一行。我尝试了此操作，但仍然存在相同的问题。请在循环中尝试触摸位置查看我的编辑，我在两个位置尝试了此操作，但都不起作用。

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint touchLocation = [touch locationInNode:self];


for (UITouch *touch in touches) {
    if (touchLocation.x < self.size.width / 2.0f) {
        touching = YES;
    }

    if (touchLocation.x > self.size.width / 2.0f) {
        if (![rocketFlame parent]) {
            [self fireRocket];
        }
    }
}

for (UITouch *touch in touches) {

CGPoint touchLocation = [touch locationInNode:self];
if (touchLocation.x < self.size.width / 2.0f) {
    touching = YES;
}

if (touchLocation.x > self.size.width / 2.0f) {
    [self drawRocket];
}
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UITouch *touch in touches) {

        // The following statement is causing the issue. Delete it.
        //UITouch *touch = [touches anyObject];

        CGPoint touchLocation = [touch locationInNode:self];

        if (touchLocation.x < self.size.width / 2.0f) {
            touching = YES;
        }

        if (touchLocation.x > self.size.width / 2.0f) {
            if (![rocketFlame parent]) {
                [self fireRocket];
            }
        }
    }
}
