An example of an antispam check

I've seen a few people still struggling with this, so here is my participation.
This simple commented example script shows you how to avoid command/function spamming.
I wrote this for beginners, so it's heavily commented.
Hope it helps!

Code

PHP Code:


		
			
#include <sourcemod>
#pragma semicolon 1




// Define a global array where the times will be stored on the client
new g_iPlayerSpamTime[MAXPLAYERS+1];



// This is kind of a spamcheck spamcheck
new bool:g_bPlayerHadMessage[MAXPLAYERS+1];



// Define the time after which we allow the command again
#define SPAMTIME 5





public OnPluginStart()
{
    RegConsoleCmd("sm_test", Command_Test);
}





public Action:Command_Test(client, args)
{
    // I do no validity checky here because ths is just an example, but don't forget to do it.
    
    // Check if the client has a stored time, if not let him pass and store it
    // I use GetTime here, you can also use GetGameTime/GetEngineTime and fit it to your needs.
    if(g_iPlayerSpamTime[client] == 0 || g_iPlayerSpamTime[client] <= ( GetTime() - SPAMTIME ))
    {
        // Set the time
        g_iPlayerSpamTime[client] = GetTime();
        
        // Set the appeared message to false
        g_bPlayerHadMessage[client] = false;
        
        // Your function or command
        ExampleFunc(client);
    }
    // If he is not allowed to use the command send him a message
    // We only want this message to appear 1 time, else our spamcheck wouldn't make any sense
    else if(!g_bPlayerHadMessage[client])
    {
        // Send a message when he can approximately use the command again.
        ReplyToCommand(client, "You are not allowed to use this command in the next %d seconds", SPAMTIME - ( GetTime() - g_iPlayerSpamTime[client] ));
        
        // Set to true that he seen the message
        g_bPlayerHadMessage[client] = true;
    }
    

    return Plugin_Handled;
}





ExampleFunc(client)
{
    ReplyToCommand(client, "Command has run");
}





// Of course don't forget to reset the time if it is a long time
public OnClientPostAdminCheck(client)
{
    g_iPlayerSpamTime[client] = 0;
    g_bPlayerHadMessage[client] = false;
}




// Of course don't forget to reset the time if it is a long time
public OnClientDisconnect_Post(client)
{
    g_iPlayerSpamTime[client] = 0;
    g_bPlayerHadMessage[client] = false;
}

Yours sincerely
