debug.setlocal ([thread,] level, local, value)
This function assigns the value value
to the local variable with index local
of the function at level level
of the stack. The function returns nil if there is no local variable with the given index, and raises an error when called with a level
out of range. (You can call getinfo
to check whether the level is valid.) Otherwise, it returns the name of the local variable.
See debug.getlocal
for more information about variable indices and names.
