setTimer variable scope bug

[JeViCo]

I've recently tried to do something like this

function drawSlot()

end
addEventHandler("onClientRender", root, drawSlot)
setTimer(removeEventHandler, 3000, 1, "onClientRender", root, drawSlot)

however i keep getting warning: 'removeEventHandler' expected function at argument 3 got nil
everything works fine by the code below:

setTimer(function()
	removeEventHandler("onClientRender", root, drawSlot)
end, 3000, 1)

Is that mta bug?
btw _G["drawSlot"] gives same warning

It is a limit. Timer are an async method. It requires a lot more work to keep temporary variables alive. So timers will make copies of the values rather managing the original values.

- You can't pass functions in to a timer as argument. (They can't be copied)

- You can pass tables in to a timer as argument, but they will become a (deep) copy.

By doing this am I avoiding this deeeeep copy?

local myTable = {} -- Some filled in table

setTimer(function()
  callAnotherFunction(myTable)
end, 1000, 1)
