我正在尝试制作一个简单的隧道采矿龟。我试图在挖掘时显示有关海龟的一些信息。例如，进度和油耗。

挖掘实际隧道和显示信息的过程/功能应该同时运行，但此时它并没有真正做到这一点。

我尝试使用并行 API，但它并没有按照我想要的方式工作。

这是我到目前为止的代码：

--Starting Conditions--
HeightQuestion = true
WidthQuestion = true
LengthQuestion = true
BlocksToMine =0
EstBlocksDone =0
BlocksDone =0
BlocksToDo =0
screen = 0


function FuncFuel()
    if turtle.getFuelLevel() < 10 then
        turtle.refuel()
        print("fuel level: " .. turtle.getFuelLevel() ..  "/".. turtle.getFuelLimit())
    else
        print("fuel level: " .. turtle.getFuelLevel().. "/".. turtle.getFuelLimit())
    end 
end

function FuncHeight()
    while (HeightQuestion == true) do -- Height Question
        print("Height of tunnel?")
        IniHeight = tonumber(read())
        if IniHeight == nil then
            print( "Please answer with a number." )
        elseif IniHeight >= 2 then
            HeightQuestion = false
        elseif IniHeight == 1 then
            print( "The tunnel Height must be larger than one." )
        elseif IniHeight == 0 then
            print( "The tunnel Height can't be infinite." )
        else
            print( "The tunnel Height must be positive." )
        end
    end
    Height=IniHeight
 end

function FuncWidth()
    while (WidthQuestion == true) do -- Width Question
        print("Width of tunnel?")
        IniWidth = tonumber(read())
        if IniWidth == nil then
            print( "Please answer with a number." )
        elseif IniWidth > 0 then
            WidthQuestion = false
        elseif IniWidth == 0 then
            print( "The tunnel Width can't be infinite." )
        else
            print( "The tunnel Width must be positive." )

    end

        elseif IniLength > 0 then
            LengthQuestion = false
        elseif IniLength == 0 then

            InfiniteLength = true
            TorchesQuestion = false
            TorchSpacingQuestion = false
        else
            print( "The tunnel Length must be positive." )
        end
    end
    Length=IniLength

与同时运行的进程无关，而是与您的第一个功能有关FuncFuel 

function FuncFuel()
    if turtle.getFuelLevel() < 10 then
        turtle.refuel()
        print("fuel level: " .. turtle.getFuelLevel() ..  "/".. turtle.getFuelLimit())
    else
        print("fuel level: " .. turtle.getFuelLevel().. "/".. turtle.getFuelLimit())
    end 
end

我会把它改成

function FuncFuel()
    if turtle.getFuelLevel() < 10 then
        turtle.refuel()
    end 
    print("fuel level: " .. turtle.getFuelLevel().. "/".. turtle.getFuelLimit())
end

还具有FuncHeight功能的线条 

elseif IniHeight == 0 then
    print( "The tunnel Height can't be infinite." )

如果他们回答0then 他们并不意味着infinite他们的意思是没有高度，你仍然不能拥有，所以将错误更改给用户，同样适用FuncWidth

正如约翰已经说过的

并行需要使用 Yield 调用来允许不同的线程运行。

这几乎可以在 Computercraft API 的任何函数中完成。你不需要打电话coroutine.yield()。

假设您的功能MineScreenProcess和FuncTunnel工作正常（我没有检查他们的代码），您parallel.waitForAll(...)在最后或您的脚本调用以开始执行。这一切都很好，也需要。但是你的论点是错误的。

parallel.waitForAll(...)want 是指向要运行的函数的“指针”。您没有将函数的指针作为参数传递。您正在传递函数的结果。

您可以尝试更改：

parallel.waitForAll(MineScreenProcess(), FuncTunnel())

至：

parallel.waitForAll(MineScreenProcess, FuncTunnel)

您不能在 ComputerCraft 中拥有真正的并行性。协程允许一些伪并行性，但仅此而已。

尝试这个：

while true do
  parallel.waitForAny(MineScreenProcess(), FuncTunnel())
end

基本上，当一个人返回时，它会再次运行它们，因此它可以不断地同时运行它们。

并行需要使用 Yield 调用来允许不同的线程运行。查看文档并添加 Yield 调用以允许其他线程运行。最常见的方法是每个循环添加一次。如果您的隧道函数每个循环产生一次，则屏幕进程可以运行。每次都必须让屏幕进程让隧道功能恢复。
