This event is triggered when a player issues a command.

[[{{{image}}}|link=|]] Note: This event triggers regardless of whether the command exists in a script or is hardcoded. Also, typing anything in chat will execute the internal command "say", so this event will be triggered on every chat message as well. Therefore you should avoid excessive use of this function on busy servers, out of performance considerations.

Parameters

string command

Source

The source of this event is the player who tried to execute a command.

Result of cancelling this event

The command will not be executed.

Example

Click to collapse [-]
Server

This example implements an anti-flood protection timer for commands. Be sure to give the resource a function.kickPlayer right. Also, note, that if the server freezes for a frame and a player executes a command 2x he/she'll get kicked, because those 2 commands will be processed after each other, with very little delay 

local CMD_INTERVAL        = 200 --// The interval that needs to pass before the player can execute another cmd
local KICK_AFTER_INTERVAL = 50  --// Kick the player if they execute more than 20 cmds/sec

local executions = setmetatable({}, { --// Metatable for non-existing indexes
    __index = function(t, player)
        return getTickCount()-CMD_INTERVAL
    end
})

addEventHandler("onPlayerCommand", root,
    function()
        if (executions[source]-getTickCount()<=CMD_INTERVAL) then
            if (executions[source]-getTickCount()<=KICK_AFTER_INTERVAL) then 
                kickPlayer(source, "Anti-Flood", "Don't flood")
            end 
            cancelEvent()
        end
        executions[source] = getTickCount()
    end
)

This example disables the hardcoded command 'whois' 

addEventHandler("onPlayerCommand",root,
    function(command)
	if (command == "whois") then
	    cancelEvent()
	end
end)
