c# - 如何将速度值从 0,002543535 更改为 0

Question

我试图将速度值从 0,002543535 更改为 0，但我不知道该怎么做以及将代码放在哪里。

using AssettoCorsaSharedMemory;
using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            AssettoCorsa ac = new AssettoCorsa();
            ac.StaticInfoInterval = 500; // Get StaticInfo updates ever 5 seconds
            ac.StaticInfoUpdated += ac_StaticInfoUpdated; // Add event listener for StaticInfo
            ac.PhysicsInterval = 500;
            ac.PhysicsUpdated += ac_PhysicsUpdated;
            

        ac.Start(); // Connect to shared memory and start interval timers 

            Console.ReadKey();
        }

        static void ac_StaticInfoUpdated(object sender, StaticInfoEventArgs e)
        {
            // Print out some data from StaticInfo
          //  Console.WriteLine("StaticInfo");
          //  Console.WriteLine("  Car Model: " + e.StaticInfo.CarModel);
          //  Console.WriteLine("  Track:     " + e.StaticInfo.Track);
          //  Console.WriteLine("  Max RPM:   " + e.StaticInfo.MaxRpm);

        }

        static void ac_PhysicsUpdated(object sender, PhysicsEventArgs e)
        {
            // Print out some data from StaticInfo

              Console.WriteLine("  Speed:   " + e.Physics.SpeedKmh);
          //  Console.WriteLine("  Gear:   " + e.Physics.Gear);
          //  Console.WriteLine("  TC:   " + e.Physics.TC);
              Console.WriteLine("  RPM:   " + e.Physics.Rpms);

        }
    }
}

这是声明 SpeedKmh 的代码

当我的车不移动时，我得到了图片上的速度值，有人知道如何将其更改为 0 吗？____________________________________________________________________________________________

可能在这里（没有看到其他任何可能的地方）：

static void ac_PhysicsUpdated(object sender, PhysicsEventArgs e)
{
    Console.WriteLine("  Speed:   " + e.Physics.SpeedKmh); // <---
    // ...
}

您可以使用System.Math.Round方法来获取最接近的整数值或显式强制int类型：

float speed = e.Physics.SpeedKmh; // <-- 0.002543535 (float type)
double dRoundedSpeed = Math.Round(speed); // <-- 0 (double type)
float fRoundedSpeed = (float)Math.Round(speed); // <-- 0 (float type)
int iRoundedSpeed = (int)speed; // <-- 0 (int type)
