IfElse

From Multi Theft Auto: Wiki

Jump to: navigation, search

This function just adds a possibility to integrate a condition in e.g. some variable definition. It is as useful as simple. It's like the short ”(c) ? t : f ;“ statement that exists in e.g. PHP or JavaScript.

Note: This function is basically on the wiki to enable using it in other useful functions.

Syntax

var IfElse( bool condition, var trueReturn, var falseReturn )

Required Arguments

  • condition: A condition like you could use it in an if-statement.
  • trueReturn: The value that should be returned if the condition is true.
  • falseReturn: The value that should be returned if the condition is false.

Returns

Returns the second argument if condition is true, the third otherwise.

Server

This example adds a command to retrieve the actual player count.

-- define the commandhandler function
function CmdPlayerCount(source)
    -- get the actual player count
    local playerCount = getPlayerCount()
    -- send message to the player
    outputChatBox("There "..IfElse(playerCount == 1, "is", "are").." actually "..playerCount.." Player"..IfElse(playerCount == 1, "", "s").." online.", source)
end
-- add the command handler
addCommandHandler("playerCount", CmdPlayerCount, false, false)
