Question

执行此功能时，只显示第二个io.read，第一个被忽略：

function playernames ()
    os.execute ("cls")
    io.write ("\n Player 1, choose a name: ")
    playername1 = io.read ()
    os.execute ("cls")
    io.write ("\n Player 2, choose a name: ")
    playername2 = io.read ()
end

如何正确显示第一个io.read？

Answer 1

不是我对Lua知之甚少，所以这是一个疯狂的猜测，但不应该是：

function playernames ()
    os.execute ("cls")
    io.write ("Player 1, choose a name: ")
    playername1 = io.read ()
    io.write ("\n")
    os.execute ("cls")
    io.write ("Player 2, choose a name: ")
    playername2 = io.read ()
    io.write ("\n")
end

Answer 2

好“cls”将清除屏幕，所以如果你想在键入它们后仍然在屏幕上，你需要删除第二个“cls”：

function playernames ()
    os.execute ("cls")
    io.write ("\n Player 1, choose a name: ")
    playername1 = io.read ()
    io.write ("\n Player 2, choose a name: ")
    playername2 = io.read ()
end

playernames ()

如果你只想展示它们，那么：

function playernames ()
    os.execute ("cls")
    io.write ("\n Player 1, choose a name: ")
    playername1 = io.read ()
    os.execute ("cls")
    io.write ("\n Player 2, choose a name: ")
    playername2 = io.read ()
    os.execute ("cls")
    io.write ("Player 1: "..playername1.."\n") --or use print here
    io.write ("Player 2: "..playername2.."\n")
end

playernames ()

否则，如果这不是你要找的答案，你应该指明 “我如何正确显示第一个io.read？”。

在Lua的io.read并不起作用
