CallClientFunction

This function allows you to call any clientside function from the server's side. Of course only those which are available clientside. 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 clientside to avoid data being lost. If you don't need this feature just delete it.

Syntax

nil CallClientFunction( element client, string funcname, [ var argument1, ... ] )

Required Arguments

• client: The element of the player who should be affected.
• funcname: The name of the function that should be called clientside. 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.

Server

This example sets the player's minute duration.

-- get the root element
local _root = getRootElement()
-- define the onPlayerJoin handler function
function OnPlayerJoin()
    -- set the minute duration
    CallClientFunction(source, "setMinuteDuration", 10000)
end
-- add the event handler
addEventHandler("onPlayerJoin", _root, OnPlayerJoin)
