Question

我正在尝试制作一个简单的隧道采掘龟。我试图在挖掘时显示关于乌龟的一些信息。例如，进度和燃料消耗。

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，但它并没有像我想要的那样工作。

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." )

        end
    end

Answer 1

约翰已经说过了

Parallel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的任何功能中完成。您不需要致电coroutine.yield()。

假设您的函数MineScreenProcess和FuncTunnel工作正常（我没有检查过他们的代码），您最后会调用parallel.waitForAll(...)或脚本启动执行。这一切都很好，也需要。但你的论点是错误的。

parallel.waitForAll(...)想要＆＃34;指针＆＃34;到你想要运行的功能。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())

为：

parallel.waitForAll(MineScreenProcess, FuncTunnel)

Answer 2

与您的第一个函数FuncFuel

同时运行的进程无关

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

使用FuncHeight功能行

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

如果他们用0回答，那么他们并不意味着infinite他们的意思是没有高度，你仍然不能拥有，所以将错误更改为用户，同样适用于{{1} }}

Answer 3

试试这个：

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，因此它可以同时运行。

Answer 4

Parallel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。如果你的隧道函数每个循环产生一次，那么屏幕进程就可以运行了。每次屏幕进程都必须允许隧道功能恢复。

Answer 5

你无法在ComputerCraft中拥有真正的并行性。协同程序允许一些伪并行，但这就是你得到的。

Computercraft Lua多个进程同时运行
