Why is it printing 'nil', when it should be printing a random number? (notice me '3')
I was just testing things out, but on the last line print(xPosition), it is printing 'nil', how do I prevent that from happening?
local xPosition
local AmountOfCash
local corouti = coroutine.create(function()
while wait() do
AmountOfCash = Player.leaderstats.Cash.Value
end
end)
coroutine.resume(corouti)
local genRandomNumber = coroutine.create(function()
while wait() do
xPosition = math.random(0.200, 0.500)
end
end)
coroutine.resume(genRandomNumber)
print(xPosition)

I believe it is due to while wait() do. During that wait() the thread is paused and print(xPosition) runs, therefore returning a value of nil.
Since the coroutine is a separate thread, the local variable xPosition is outside the scope and so the xPosition within the loop is not the same variable.
You can remedy this by making xPosition a global variable and assigning it a value and putting a print inside the genRandomNumber coroutine.
xPosition = 0
local genRandomNumber = coroutine.create(function()
while wait() do
xPosition = math.random(0.200, 0.500)
print(xPosition)
end
end)
coroutine.resume(genRandomNumber)
As a side note, if you want a decimal then you need to be doing something like this:
local x = math.random(2, 5)/100
