Question

当我运行我的游戏时，它在对象碰撞的底部工作正常但是，它不会分散那个和另一个。它不是在阅读第二个。我拍了一张照片，你可以看到（x，y）坐标，它符合条件，但我仍然可以移动。

变化：

    else if(x > 370 && x < 531 && y > 223){ // Check for 3 values 
        ya = 0;
        System.out.println("+x");
        /*
         * Use the gravity() method to determine player fall rate
         */
    }

为：

    if(x > 370 && x < 531 && y < 286){ // Check for 3 values 
        y = y + 4; 
        System.out.println("-x");
        /*
         * Use the gravity() method to determine player fall rate
         */
    }

    if(x > 370 && x < 531 && y > 223){ // Check for 3 values 
        ya = 0;
        System.out.println("+x");
        /*
         * Use the gravity() method to determine player fall rate
         */
    }

原因是关键字＆＃34; else＆＃34;只有在上面的＆＃34; if＆＃34;声明的条件失败/要求未得到满足。例如：

boolean anInteger = 9;
if (anInteger == 1999) {
    // ...
} else {
    // If 'anInteger' is not equal to 9, then execute the following code (within this block)
    // ...
}

程序没有检查第二个条件
