浮动比较不匹配 [英] Float comparison mismatch

问题描述

我有一个非常奇怪的错误，我无法弄清楚。

I have an extremely weird error that I cannot figure out.

float distance = Utils.distance(this.spriteStartX, this.spriteStartY, this.getX(), this.getY());

Utils.log("D_Check: "+distance+" >= "+this.spriteDistance);

if(distance >= this.spriteDistance);
{
    Utils.log(distance+" is greater than "+this.spriteDistance);
}

在这段代码中，我确定了我的精灵来源与其当前之间的距离地点。 （为简单起见，这是8.034246f）。 this.spriteDistance是7000.0f。

In this code I determine the distance between where my sprite originated and its' current location. (for the sake of simplicity, this is 8.034246f). this.spriteDistance is 7000.0f.

在我收到的调试器中：

D_Check: 8.034246 >= 7000.0
8.034246 is greater than 7000.0

显然是某事这是非常错的。我错过了一些非常简单的东西吗？

Obviously something is very wrong with this. Have I missed something incredibly simple?

推荐答案

在if语句后删除分号。

Remove the semicolon after the if statement.

if (distance >= this.spriteDistance)
{
    Utils.log(distance+" is greater than "+this.spriteDistance);
}
