首先，我编写了一个简单的代码，根据 x 和 y 坐标给出的 4 个点检查 2 条线是否发生碰撞。它检查两条线的角度（我的代码中的变量 k ）是否相同，在这种情况下它们是平行的，否则它们会发生碰撞。角度 (k) 是根据数学方程计算得出的，单击此处[k = (y2-y1)/(x2-x1)]。现在我不知道如何理解他们的冲突点。如果你能帮助我，我将不胜感激。先感谢您。
我的代码：（我调用计算角度的方法）
static void MetodaTrazenjaPresjeka(Duzina d1, Duzina d2)
{
int k11 = d1.Krajy - d1.Pocy; //y2-y1 - first line
int k12 = d1.Krajx - d1.Pocx; //x2-x1 - first line
double k1 = (double)k11 / k12; //angle of the first line
int k21 = d2.Krajy - d2.Pocy; //y2-y1 - second line
int k22 = d2.Krajx - d2.Pocx; //x2-x1 - second line
double k2 = (double)k21 / k22; //angle of the second line
if (k1 == k2)
{
//they are parallel
Console.WriteLine("MOJA METODA:");
Console.WriteLine("-----------------------------------");
Console.Write("Pravci zadani tockama su paralelni!");
}
else
{
//lines are colliding
Console.WriteLine("MOJA METODA:");
Console.WriteLine("-----------------------------------");
Console.Write("Pravci zadani tockama se sijeku!");
}
}
Duzina 类中的代码：
class Duzina
{
private int pocx, pocy, krajx, krajy;
//read/write attribute for the x coordinate of the first point
public int Pocx
{
get { return pocx; }
set { pocx = value; }
}
//read/write attribute for the y coordinate of the first point
public int Pocy
{
get { return pocy; }
set { pocy = value; }
}
//read/write attribute for the x coordinate of the second point
public int Krajx
{
get { return krajx; }
set { krajx = value; }
}
//read/write attribute for the y coordinate of the second point
public int Krajy
{
get { return krajy; }
set { krajy = value; }
}
//method that will print out coordinates of the given points
public void Ispis()
{
Console.Write("Pocetna tocka: ({0},{1})",Pocx,Pocy);
Console.Write("Krajnja tocka: ({0},{1})", Krajx, Krajy);
}
}
