First you need the Object Gate which is Closed. You link this object with a variable. For an example starsgate.
First add this at the top of the script.

pawn Код:

new starsgate; //This is the variable

Now link the Variable with the Object:

pawn Код:

starsgate = CreateObject(...); //This is the Gate which is CLOSED

Next we have to create the command under OnPlayerCommandText:

pawn Код:

if(strcmp(cmd, "/starsgate", true) == 0) //This is the Command

Next we have to ask if he is in the gang "stars" ( I think its something like a Gang ). For this step you need to get the number of the gang. I chose 3. BUT: This Step depends on the script...

pawn Код:

if(strcmp(cmd, "/starsgate", true) == 0)
{
      if(PlayerInfo[playerid][pLeader] == 3 || PlayerInfo[playerid][pMember] == 3) 
      //Asks if playerid is in gang 3

Now we have to add the function with MoveObject:

pawn Код:

if(strcmp(cmd, "/starsgate", true) == 0)
{
      if(PlayerInfo[playerid][pLeader] == 3 || PlayerInfo[playerid][pMember] == 3)
      {
            MoveObject(starsgate,x-pos,y-pos,z-pos,The speed of which the object will be moved with);
            //Moves the Object
      }
      else
      {
            SendClientMessage(playerid,COLOR,"You are not in the Stars"); 
            //If playerid is NOT in gang 3 send the message
      }
}

Now the Gate will open if you type in /starsgate, but just if you are in Stars. To close it you can do the same thing again:

pawn Код:

if(strcmp(cmd, "/closestarsgate", true) == 0)
{
      if(PlayerInfo[playerid][pLeader] == 3 || PlayerInfo[playerid][pMember] == 3)
      {
            MoveObject(starsgate,x-pos,y-pos,z-pos,The speed of which the object will be moved with);
      }
      else
      {
            SendClientMessage(playerid,COLOR,"You are not in the Stars"); 
      }
}

But when you do not have "PlayerInfo" then try this:

pawn Код:

new PlayerInfo[MAX_PLAYERS][pInfo];
enum pInfo
{
      pLeader
      pMember
}

And now script this: if playerid is in the stars set [pMember] = 3 and if playerid is the leader of the stars set [pLeader] = 3.
