ios - Objective-c 为 iPhone 游戏制作关卡

Question

我有一个问题游戏，我在其中问用户一些问题，并根据用户正确回答的速度和用户所处的级别，我希望用户获得不同数量的 xp/进度，用于我的进度 View 有。

所以我有一个名为“levelInt”的全局变量，它保存用户所处级别的值(最高级别为 20)。我还有一个打印“levelInt”变量的标签和一个进度 View ，显示您进入更高级别的进度/显示当前级别的进度。我还有一个计时器，从 2 分钟开始倒计时，根据您回答这个问题的速度，您可以获得更多 xp/进度 View 的更多进度。我是这样设置的:

• totalSeconds 是计时器

• levelInt 是全局变量，保存用户所在级别的值

• progressView 是进度条，显示下一级之前剩余的 xp

和代码:

    progressView.progress = .60;

    progressView.progress = .40;

    progressView.progress = .20;

}else if ( levelInt == 1 && totalSeconds > 80 ){
    progressView.progress = .15;

问题是，每当我快速正确回答 20 秒时，进度 View 只会增加大约 .10。我应该做 progressView.progress = progressView.progress + (amount) 吗？

Answer 1

第一个或第二个语句将始终验证 true ,
因此最后三个if语句永远不会被验证。
数字无法验证 false到两个<= 100和 > 100 .
数字验证 false至 > 100总是<= 100 .

if ( i > 100 ) 
{
    // All numbers above 100 
} 
else if ( i <= 100 ) 
{
    // All numbers lower than or equal to 100
} 
else if ( i > 80 ) 
{
    // Never reached
} 
else if ( i <= 80 ) 
{
    // Never reached
} 
else 
{
    // Never reached
}
