vb6.0小游戏贪吃蛇代码

贪吃蛇是一款经典的小游戏，下面是一个简单的VB6.0贪吃蛇代码示例：

Private Sub Form_Load()
    Me.ScaleMode = vbPixels
    Me.Width = 400
    Me.Height = 400
    
    Randomize
    Dim snakeSize As Integer
    snakeSize = 20
    
    Dim numFood As Integer
    numFood = 2
    
    Dim foodX, foodY As Integer
    foodX = Int(Me.Width / snakeSize * Rnd) * snakeSize
    foodY = Int(Me.Height / snakeSize * Rnd) * snakeSize
    
    Me.AutoRedraw = True
    Me.Show
    
    Dim snake(5000) As Object
    snake(0) = Me.Circle((Int(Me.Width / (2 * snakeSize)) 
        * snakeSize, (Int(Me.Height / (2 * snakeSize))) 
        * snakeSize, snakeSize, RGB(0, 255, 0))
    
    Dim score As Integer
    score = 0
    
    Do
        If numFood = 0 Then
            foodX = Int(Me.Width / snakeSize * Rnd) * snakeSize
            foodY = Int(Me.Height / snakeSize * Rnd) * snakeSize
            numFood = 1
        End If
        
        Dim xDir, yDir As Integer
        xDir = 1
        yDir = 0
        
        Dim i As Integer
        For i = UBound(snake) To 1 Step -1
            Set snake(i) = snake(i - 1)
        Next
        
        Set snake(0) = Me.Circle(snake(0).Left + (xDir * 
            snakeSize), snake(0).Top + (yDir * snakeSize), 
            snakeSize, RGB(0, 255, 0))
        
        If snake(0).Left >= foodX And snake(0).Left <= foodX 
            + snakeSize And snake(0).Top >= foodY And 
            snake(0).Top <= foodY + snakeSize Then
            foodX = Int(Me.Width / snakeSize * Rnd) * snakeSize
            foodY = Int(Me.Height / snakeSize * Rnd) * snakeSize
            numFood = numFood - 1
            score = score + 1
        Else
            Me.PSet (snake(UBound(snake)).Left, snake(UBound(snake)).Top)-(snake(UBound(snake)).Left + snakeSize, snake(UBound(snake)).Top + snakeSize), vbBlack
        End If
        
        Sleep 50
    Loop Until False
End Sub

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
    If KeyCode = vbKeyUp Then
        xDir = 0
        yDir = -1
    ElseIf KeyCode = vbKeyDown Then
        xDir = 0
        yDir = 1
    ElseIf KeyCode = vbKeyLeft Then
        xDir = -1
        yDir = 0
    ElseIf KeyCode = vbKeyRight Then
        xDir = 1
        yDir = 0
    End If
End Sub

这段代码通过使用Form_Load事件和Form_KeyDown事件来控制贪吃蛇的移动和食物的生成。其中，form_load用于控制游戏的主要逻辑，包括蛇的移动、食物的生成和得分的计算，而form_KeyDown则用于对键盘输入的处理，根据不同的按键来改变蛇的移动方向。这段代码只是一个简单的示例，可能还有其他的功能和优化可以添加进去，但是这个代码已经足够实现一个简单的贪吃蛇游戏了。
