Vb.net VB 2D数组可能没有返回正确的值/需要帮助计算2D数组中布尔数

我试图用VisualBasic编写Conways生命游戏，但计算周围活细胞数量的代码似乎有问题。代码如下所示：

Module Module1

Dim ScreenHeight As Integer = 30
Dim ScreenWidth As Integer = 30
Dim Field(ScreenWidth - 1, ScreenHeight - 1) As Boolean
Dim FieldBuffer(ScreenWidth - 1, ScreenHeight - 1) As Boolean

Sub Main()
    Console.SetWindowSize(ScreenWidth, ScreenHeight)
    Field(10, 9) = True
    Field(10, 10) = True
    Field(10, 11) = True


    While True

        Dim x = 0
        While (x < ScreenWidth)
            Dim y = 0
            While (y < ScreenHeight)
                Console.SetCursorPosition(x, y)

                If ((x <> 0 And x <> ScreenWidth - 1) And (y <> 0 And y <> ScreenWidth - 1)) Then

                    Dim count = Field(x + 1, y) + Field(x - 1, y) + Field(x, y + 1) + Field(x, y - 1) _
                        + Field(x + 1, y + 1) + Field(x - 1, y - 1) + Field(x - 1, y + 1) + Field(x + 1, y - 1)

                    count = count * -1
                    If (Field(x, y) = True) Then

                        If (count < 2) Then
                            FieldBuffer(x, y) = False
                        End If
                        If (count > 3) Then
                            FieldBuffer(x, y) = False
                        End If
                        If (count = 3 Or count = 2) Then
                            FieldBuffer(x, y) = True
                        End If


                        Console.BackgroundColor = ConsoleColor.Blue
                    Else

                        If (count = 3) Then
                            FieldBuffer(x, y) = True
                        End If

                        Console.BackgroundColor = ConsoleColor.Black
                    End If

                    Console.Write(count)
                Else
                    Console.BackgroundColor = ConsoleColor.Red
                    Console.Write("X")
                End If


                y += 1
            End While
            x += 1
        End While

        Console.ReadKey()
        Field = FieldBuffer
    End While



End Sub

End Module

对于程序的第一次迭代，它返回字段数组中单元格结构的正确值。 但是在第二次迭代中，应用规则后，它不会返回正确的值，应该是： 12321 11211 12321

规则正确地应用于数组，因为在第一次迭代之后，显示的结构是正确的。当单元格周围的每个位置都有“If（Field（x，y）=true）then Count+=1”时，也会出现此错误

如果有任何帮助，我们将不胜感激，因为这个bug已经让我疯狂了大约两周了。

您的规则是错误的

' Any live cell with two or three neighbours lives
' Any dead cell with exactly three live
If count = 3 Then ' If (count = 3 Or count = 2) Then
    FieldBuffer(x, y) = True
End If

您也在复制引用。这意味着，在第二次传递时，Field和FieldBuffer是相同的

Field = FieldBuffer

您需要复制每个项目。使用循环，类似或

Field = FieldBuffer
