在QB64中通过网络接收和发送字符串
问题描述:
我正在为我的兄弟工作在网络上的迷你口袋妖怪游戏。 不幸的是,在测试时,我发现出于某种原因,它只在尝试向另一台计算机发送字符串的行上出现“错误的文件名或数字”错误,但在循环接收命令时没有错误。在QB64中通过网络接收和发送字符串
这里是我的代码:
SCREEN 12
CLS
PRINT ""
PRINT ""
PRINT ""
PRINT ""
PRINT ""
PRINT " POKELITE - By Mark "
PRINT ""
PRINT ""
INPUT "Join or Host a game? ", hostorjoin$
hostorjoin$ = UCASE$(hostorjoin$)
IF hostorjoin$ = "JOIN" THEN GOTO JOIN
IF hostorjoin$ = "HOST" THEN GOTO HOST
HOST:
server& = _OPENHOST("TCP/IP:300")
PRINT "Waiting for connection..."
PRINT "! Remember: If playing locally, give the other player your IPv4 Address !"
DO
HOST& = _OPENCONNECTION(server&)
LOOP UNTIL HOST& <> 0
PRINT ""
PRINT "2nd Player Joined!"
SLEEP 2
GOTO GAME
JOIN:
INPUT "Enter Server IPv4 Address (Example: 192.168.1.25): ", joinip$
handle& = _OPENCLIENT("TCP/IP:300:" + joinip$)
IF handle& = 0 THEN PRINT "Connection failed!": SLEEP 2: CLS: GOTO JOIN
GOTO GAME
GAME:
CLS
INPUT "Enter your name: ", name$
IF name$ = "" THEN GOTO GAME
PRINT "Waiting for other player..."
IF hostorjoin$ = "JOIN" THEN
PUT HOST&, , name$
DO
GET handle&, , name2$
LOOP UNTIL name2$ <> ""
END IF
IF hostorjoin$ = "HOST" THEN
PUT handle&, , name$
DO
GET HOST&, , name2$
LOOP UNTIL name2$ <> ""
END IF
PRINT name$
PRINT name2$
答
您需要确保端口可用,否则server&
将是无效的服务器手柄。 Choosing a port of 49152 or higher is generally safe。然而,这可能不是你唯一的问题。
您的问题很可能是您的连接变量根本不相同,这意味着HOST&
和handle&
应该只是handle&
。重要的是要记住,从来没有“主机句柄”和“客户端句柄”;唯一的句柄是“服务器句柄”(使用_OPENHOST
为本地连接创建一个端口)和“连接句柄”(由服务器使用_OPENCONNECTION
创建连接到客户端或_OPENCLIENT
由客户端连接到服务器)。这也将减少你的逻辑,只做一个PUT
,然后循环一个GET
。我使用名称connection&
而不是handle&
,但您明白了。
