In the top of the script

Код:

 #define dcmd(%1,%2,%3) if ((strcmp((%3)[1], #%1, true, (%2)) == 0) && ((((%3)[(%2) + 1] == 0) && (dcmd_%1(playerid, "")))||(((%3)[(%2) + 1] == 32) && (dcmd_%1(playerid, (%3)[(%2) + 2]))))) return 1

Create a boolean variable

Код:

new bool: IsPlayerInDM[MAX_PLAYERS];

Under OnPlayerConnect(playerid)

Код:

 IsPlayerInDM[playerid] = false;

Under OnPlayerCommandText(playerid, cmdtext[])

Код:

dcmd(dmjoin, 6, cmdtext);
dcmd(leavedm, 7, cmdtext);

After the "}" of the OnPlayerCommandText put this

Код:

dcmd_dmjoin(playerid, params[])
{
       #pragma unused params
       if(IsPlayerInDM[playerid] == true)
            SendClientMessage(playerid, -1, "You're Already in DM");
       else
       {
             IsPlayerInDM[playerid] = true;
             //Do the rest of things to go to dm, for example, teleport player, give him weapons, etc...
        }
       return 1;
}

Put this under OnPlayerSpawn(playerid)

Код:

if(IsPlayerInDM[playerid] == true)
      SetPlayerPos(playerid, "coord x", "coord y", "coord z") // coordinates of the dm spawn

Now the leave command

Under the "}" of dcmd_dmjoin

Код:

dcmd_leavedm(playerid, params[])
{
     #pragma unused params
     if(IsPlayerInDM[playerid] == false)
         SendClientMessage(playerid, -1, "You're not in DM");
     else
         IsPlayerInDM[playerid] = false;
     return 1;
}

I think that's all.. Didnt test it, so if there's any errors or any bugs, post them here
