C＃物理库帮助

问题描述

我目前正在用c＃编写一个名为AnotherPhys的图书馆（ []）





编辑：首先，我需要一种以有效的方式解决冲突（主要问题）的方法。其次，我希望能够保持相当简单但有效。



这个项目是为了个人利益，也是为了扩大我对c＃的理解。一旦我成功编写了这个库，我就会尝试用c ++编写。

这是到目前为止的代码：

Hi,
I am currently writing a library in c# known as "AnotherPhys" (https://github.com/bentekken/AnotherPhys[^])


edit: Firstly, I need a way of solving collisions (main issue) in an efficient manner. Secondly, I want to be able to keep it fairly simple but effective.

This project is for personal interest but also for me to broaden my understanding of c#. Once I have successfully written this library, I''m going to try and write in c++.
this is the code so far:

public class PhysicsObject
    {
        //Default Constructor
        public PhysicsObject() { }
        public PhysicsObject(double mass, double acceleration)
        {
            this.Mass = mass;
            this.Acceleration = acceleration;
        }


        int x; int y;
        double StartTime; double Time; double ChangeTime;
        double StartSpeed; double Speed; double ChangeSpeed;
        double Mass { get; set; }
        double Acceleration { get; set; }
        public double GetAccelSync()
        {
            ChangeSpeed = (Speed - StartSpeed);
            ChangeTime = (Time - StartTime);
            Acceleration = (Speed - StartSpeed) / (Time - StartTime);
            return (Speed - StartSpeed) / (Time - StartTime);
        }
        public double GetSpeedSync()
        {
            return Acceleration * ChangeTime;
        }
        public void MoveUpdate()
        {
            GetAccelSync();
        }
        /// <summary>
        /// Returns a timespan based on time change. The unit is pixels per second (p/s).
        /// Returning a TimeSpan provides more flexibility.
        /// </summary>
        /// <returns>TimeSpan</returns>
        TimeSpan GetDuration()
        {
            return TimeSpan.FromSeconds(Time - StartTime);
        }
    }
    public class PhysicsWorld
    {
        Rectangle WorldBounds;
        PhysicsObject[] PhysObjArray { get; set; }
        Timer WorldTime;
        public PhysicsWorld() 
        {
            WorldTime.Tick += new EventHandler(WorldTime_Tick);
        }


        void WorldTime_Tick(object sender, EventArgs e)
        {
            Collisions();
            
        }
        public void Collisions()
        {
            foreach (PhysicsObject obj in PhysObjArray)
            { 
                
            }
        }
        public bool Freeze()
        {
            WorldTime.Stop();
            return true;
        }
        public bool UnFreeze()
        {
            WorldTime.Start();
            return true;
        }
        
        public void AddPhysObj(PhysicsObject PhysObj)
        {
            PhysObjArray[PhysObjArray.Length] = PhysObj;
        }


        double GravityValue { get; set; }
        public void SetGravity(double gravity)
        {
            this.GravityValue = gravity;
        }
    }

推荐答案

for (i=0; n<physobjarray.length-1; i++)   {
  for (j=i+1; n<physobjarray.length; j++)    {
    if (  PhysObjArray[i].x == PhysObjArray[j].x && PhysObjArray[i].y == PhysObjArray[j].y)
    {
      // collision detected here
    }
  }
}

顺便说一下你的碰撞 methjod应该自己处理碰撞（这是它们的后果）或者返回一个包含碰撞对象的数组。

By the way your Collisions methjod should either handle itself the collions (that is their consequences) or return an array containing colliding objects.
