LibRPC Examples
The new version of LibRPC (of this article) is about to be released
New functions Fa, RFCa was added to library for raw calling of functions with a specified environment class or instance. Earlier the 'this' was always the roottable. By using "compilestring", one do not need Fa and RFCa.
The Problem
F("MyFunction")(p1, p2, ... )
MyFunction.call(getroottable(), p1, p2, ... )
Suppose i want to callMyFunction.call(m, p1, p2, ... ) where m is a table other than roottable. Then it was not possible.
It is for this reason that new function Fa is introduced.
The Working
This leads to error
Fa("MyFunction")(m, p1, p2, ... )
because the key MyFunction will be looked inside table m. So if MyFunction is in roottable, the correct code will be
Fa(F("rawget")("MyFunction"))(m, p1, p2, ... )
When the parameter is not "string", then it will work as expected.
Example One
Let us see an example. Suppose that in roottable of server a table 'C' exists which has a slot named 'a' whose value is 3. Now we are printing that value on server console from npc ( npc must be admin to print. Not only print, but actually for executing any functions remotely ). On serverside, what we want is
print(C.rawget("a"))
Corresponding remote function call would be
RFC("print")( Fa("rawget")( F("rawget")("C"), "a" ) )
Note: F will rawget from roottable while Fa will rawget from its first parameter. F("rawget")("C") will return the table C.
