为什么 IF/ELSE 命令在我的批处理代码中不起作用？

Question

正在尝试让程序运行多人合作模式，但我的批处理脚本不工作，我想我已经搞砸了。试着找一个朋友帮忙，结果是这样，但根本行不通，我失去了所有的进步。谁能告诉我这里有什么问题 and/or 更正一下？

:hostmpcoop
set /p files="(Optional) Enter stuff to run spaced by -file : "
set /p playercount="Enter number of desired players: "
if "%files%"=="" (
    echo No files entered.
    if not "%playercount%" == "" (
        echo Running vanilla MP
        thing.exe -host %playercount% 
    )else(
        echo You need to specify a playercount!
        goto hostmpcoop
    )
)
if not "%files%"=="" (
    if not "%playercount%"=="" (
        thing.exe -host %playercount% -file %files%
    )else(
        echo You need to specify a playercount!
        goto hostmpcoop
    )
)
if "%files%"==""(
    if "%playercount%"=="" (
        echo "Enter a player count!"
        goto hostmpcoop
    )
)
goto home

当使用 else 和 if 时，括号两边需要空格：

:hostmpcoop
set /p files="(Optional) Enter stuff to run spaced by -file : "
set /p playercount="Enter number of desired players: "
if "%files%"=="" (
    echo No files entered.
    if not "%playercount%" == "" (
        echo Running vanilla MP
        thing.exe -host %playercount% 
    ) else (
        echo You need to specify a playercount!
        goto hostmpcoop
    )
)
if not "%files%"=="" (
    if not "%playercount%"=="" (
        thing.exe -host %playercount% -file %files%
    ) else (
        echo You need to specify a playercount!
        goto hostmpcoop
    )
)
if "%files%"=="" (
    if "%playercount%"=="" (
        echo "Enter a player count!"
        goto hostmpcoop
    )
)
