I have a timer-hotkey script that performs teleportation,it checks whether a key is pressed or not every 10 milliseconds and if it is pressed then it calls a function boost.The boost function reads 3 values and stores those values into 3 local variables namely x,y,z.Now it performs some calculations on these 3 local variables and stores the result into the same memory locations(from which it read) only after checking whether a key is pressed or not.The problem is that when I press the key that performs the reading and then when I press the key that stores the values of x,y,z back to the memory location,it shows an error like "performing arithmetic on a nil value global z".

I dont know how z is global and how it is nil?

Here is the lua script:

This [then] local x ... [end] form a scope block, said B, environment outside this block cannot see this [local x] value.
There may be other x declaration outside this block,
but not referenced the intended x,y,z declaration within the block B.

Move the local x,y,z declaration (only declaration, no need also the assgnemnt) should fix it,ie.

Thanks a lot dude.
I was so frustrated with the problem that I implemented this teleport hack in assembly.
But your solution really helped me out.

Why did you do the declaration twice (in the first code)?

I was aware of the CreateHotkey() but never tried it because I didn't know how to use it.
