刚做了一个模拟坦克行走，射击的动画（坦克有点粗糙了，呵呵），希望对图像进阶的编程爱好者起到抛砖引玉的效果，这里发出源码

Private a，b As Double
Private m, n As Double
Private flag, check As Integer
Private boom As Integer






Private Sub Form_Load() '坦克初始位置向上
SendKeys "W"
End Sub

Private Sub P_Keydown(KeyCode As Integer, Shift As Integer)

If a >= -9.55 And (KeyCode = vbKeyA Or KeyCode = vbKeyA + 32) Then 'A
P.Cls
a = a - 0.2
P.DrawWidth = 15
P.PSet (a, b), vbBlue
P.DrawWidth = 2
P.Line (a, b)-(a - 0.5, b), vbRed
flag = 1                                       ’标记坦克方向，为发射方向做基础
End If

If a <= 9.55 And (KeyCode = vbKeyD Or KeyCode = vbKeyD + 32) Then 'D
P.Cls

End If

End Sub

End If

If check = 4 Then
P.Line (m, n)-(m, n - 0.2), vbRed
n = n - 0.2
End If

If m <= -9.8 Or m >= 9.8 Or n <= -9.8 Or n >= 9.8 Then  ‘子弹越界的话，给坦克重装子弹，还原发射位置
m = 0
n = 0
boom = 0
P.Cls

End If
End Sub
