pygame按键约定

问题描述

我想使用w a s d键移动而不是使用箭头键但是我不知道如何用下面的代码来做到这一点。我要替换pygame.KEYDOWN 带有s的按钮，但我不知道该怎么做。

if event.type == pygame.KEYDOWN:
    if event.key == pygame.K_LEFT:
        Pacman.changespeed(-30,0)
    if event.key == pygame.K_RIGHT:
        Pacman.changespeed(30,0)
    if event.key == pygame.K_UP:
        Pacman.changespeed(0,-30)
    if event.key == pygame.K_DOWN:
        Pacman.changespeed(0,30)

解决方法

您不需要更改事件类型。 w ， a ， s ， d 用Dim dsDataSet As New DataSet Dim ConnectionString As String Dim daDataAdapter As OleDb.OleDbDataAdapter Dim dBaseConnection As New System.Data.OleDb.OleDbConnection Dim strFilePath As String = gloStrPath & "data" Dim strDBF As String = "HISTORY.DBF" Try ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strFilePath & ";Extended Properties=dBase III;" dBaseConnection = New System.Data.OleDb.OleDbConnection(ConnectionString) If dBaseConnection.State = 0 Then dBaseConnection.Open() Catch ex As Exception MsgBox(ex.Message,16,"Error") End Try Try daDataAdapter = New OleDb.OleDbDataAdapter("select * from " & strDBF,dBaseConnection) daDataAdapter.Fill(dsDataSet,"Name") Catch ex As Exception MsgBox(ex.Message,"Error") End Try，pygame.K_w表示， pygame.K_a和pygame.K_s，但事件类型仍为pygame.K_d：

pygame.KEYDOWN

注意：if event.type == pygame.KEYDOWN: if event.key == pygame.K_d: Pacman.changespeed(-30,0) if event.key == pygame.K_a: Pacman.changespeed(30,0) if event.key == pygame.K_w: Pacman.changespeed(0,-30) if event.key == pygame.K_s: Pacman.changespeed(0,30)并不意味着“向下”键，而是按下了一个键。按下键时会发生KEYDOWN事件，而释放键时会发生KEYDOWN事件。参见pygame.event和pygame.key。
