AddCommandHandler

This function will create a console command and attach it to a function, so that whenever a player or administrator uses the command the function is called.

Multiple command handlers can be attached to a single function, and they will be called in the order that the handlers were attached.

Syntax

bool addCommandHandler ( string commandName, string handlerFunction )

Required Arguments

• commandName: This is the name of the command you wish to add. This is what must be typed into the console to trigger the function.
• handlerFunction: This is the name of the function that you want the command to trigger. This function should take two parameters, playerSource and commandName followed by as many parameters you expect after your command.

player playerSource, string commandName, string args ... 

• playerSource: The player who triggered the command. If not triggered by a player (e.g. by admin), this will be false.
• commandName: The name of the command triggered. This is useful if multiple commands go through one function.
• args: Each word after command name in the original command is passed here in seperate variables. If there is no value for an argument, the variable will contain nil.

Returns

Returns true if the command handler was added successfully, false otherwise.

Example

This example defines a command handler for the command createmarker. This will create a red marker at the player who uses it's position.

-- Register the command handler and attach it to the 'consoleCreateMarker' function
addCommandHandler ( "createmarker", "consoleCreateMarker" )
-- Define our function that will handle this command
function consoleCreateMarker ( playerSource, commandName, args )
	-- If a player triggered it (rather than the admin) then
	if ( playerSource )
		-- Get that player's position
		x, y, z = getEntityPosition ( playerSource )
		-- Create a marker at their position
		createMarker ( x, y, z, 0, "checkpoint", 255, 0, 0, 255 )
		-- Output it in the chat box
		outputChatBox ( "You got a red marker", playerSource )
	end
end

Example 2: This example implements a set_vehicle_color function.

-- Register the command handler and attach it to the 'consoleCreateMarker' function
addCommandHandler ( "set_vehicle_color", "consoleSetVehicleColor" )
-- Define our function that will handle this command
function consoleSetVehicleColor ( playerSource, commandName, col1, col2, col3, col4 )
	-- If a player triggered this in-game
	if ( playerSource ) then
		-- Check we've got all 4 parameters
		if ( col1 and col2 and col3 and col4 ) then
			-- Get the player's vehicle
			playerVehicle = getPlayerOccupiedVehicle ( playerSource )
			-- Set it's color
			setVehicleColor ( playerVehicle, col1, col2, col3, col4 )
		else
			-- If we didn't get all 4 parameters, display some help text
			outputConsole ( "This function will set a vehicle's colors. A vehicle can have up to 4 colors.", playerSource )
			outputConsole ( "Syntax: set_vehicle_color color1 color2 color color4", playerSource )
		end
	end
end
