一键实现多种功能

Question

我一直在使用这段代码进行 VR 飞行模拟，效果很好。但现在我一直在尝试做的是将它从使用 9 个按钮更改为只使用一个。目前每个按钮都会激活其中一个功能，我希望它做的是 1 个按钮将循环浏览所有功能。任何帮助将不胜感激。

在函数列表中循环的函数的简单演示代码

-- put your functions into a table
local functions = {
  function () print("1") end,
  function () print("2") end,
  function () print("3") end,
}
-- initialize a counter for how often the button was pressed
local buttonCounter = 0
-- call this function every time the button is pressed
function OnButtonPress()
    -- increment counter
    buttonCounter = buttonCounter + 1
    -- call function from list
    functions[buttonCounter]()
    -- make sure to reset your counter once you've reached the last function
    buttonCounter = buttonCounter % #functions
end  
-- "press the button" 6 times
for i = 1, 6 do OnButtonPress() end
