CallServerFunction

This template is no longer in use as it results in poor readability. This function allows you to call any serverside function from the client's side. Of course only those which are available serverside. It doesn't matter if it's a MTA function, a Lua standard function or a custom function.

Numbers are automatically converted to a string and vice versa serverside to avoid data being lost. If you don't need this feature just delete it.

Syntax

nil CallServerFunction( string funcname, [ var argument1, ... ] )

Required Arguments

• funcname: The name of the function that should be called serverside. May also be a function in a table, e.g. "math.round".

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

• argument1, ...: The arguments that should be passed to the function.
