im trying to change speed value from 0,002543535 to 0 but i dont know how to do it and where to put the code.

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);

        }
    }
}

and this is code where SpeedKmh is declared

when my car is not moving im getting speed value like on the picture, anyone know how to change it to just 0? _______________________________________________________________________________________

CodePudding user response：

Probably here (didn't see anywhere else it is possible):

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

You can use System.Math.Round method to get nearest integer value or cast explicitly to int type:

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)
