游戏世界滚动：从简单位图到瓦片地图的进阶之旅

1. 简单滚动程序基础

在开发游戏世界滚动效果时，我们首先接触到的是使用简单的位图文件来实现滚动。以下是相关代码示例：

'the DirectX objects
Dim dx As DirectX8
Dim d3d As Direct3D8
Dim d3dx As New D3DX8
Dim dispmode As D3DDISPLAYMODE
Dim d3dpp As D3DPRESENT_PARAMETERS
Dim d3ddev As Direct3DDevice8
'some surfaces
Dim backbuffer As Direct3DSurface8
Dim gameworld As Direct3DSurface8
'scrolling values
Const STEP As Integer = 8
Dim ScrollX As Long
Dim ScrollY As Long
Dim SpeedX As Integer
Dim SpeedY As Integer

Private Sub Form_Load()
    'set up the main form
    Form1.Caption = “ScrollScreen”
    Form1.AutoRedraw = False
    Form1.BorderStyle = 1
    Form1.ClipControls = False
    Form1.ScaleMode = 3
    Form1.width = Screen.TwipsPerPixelX * (SCREENWIDTH + 12)
