in

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{

add this

pawn Код:

if (strcmp("/text", cmdtext, true, 5) == 0)
    {
        if(strlen(cmdtext[6])) GameTextForAll(cmdtext[6],6000,5);
        else SendClientMessage(playerid,0xFFFF00AA,"ERROR: => /text message");
        return 1;
    }

its not the best way but that should work
