Hey guys i am creating a tutorial to make a command for virtual worlds using zcmd and sscanf.

First you will need zcmd and sscanf get them from here:
ZCMD: ZCMD
sscanf:sscanf

Now lets get started.

First we will use the includes

pawn Code:

#include <a_samp>
#include <sscanf>
#include <zcmd>

I dont think i will need to tell what it means.
Now lets start the main command

pawn Code:

CMD:vw(playerid,params[])
{
new virtualworld;
if(sscanf(params,"i",virtualworld)) return SendClientMessage(playerid,-1,"USAGE: /vw [id]"); 
else
{
new str[256];
SetPlayerVirtualWorld(playerid,virtualworld);
format(str,sizeof(str),"You are now in virtual world %d",virtualworld);
SendClientMessage(playerid,-1,str);
}
return 1;
}

Now lets see what have we done here.

pawn Code:

CMD:vw(playerid,params[])
{

here we are declaring/making and starting our command using ZCMD.

NOTE: commands starting like this are NOT in "OnPlayerCommandText" function.

pawn Code:

new virtualworld;

In this we have declared a new variable ie virtualworld.

pawn Code:

if(sscanf(params,"i",virtualworld)) return SendClientMessage(playerid,-1,"USAGE: /vw [id]");

In this part we are seeing for the virtualworld id the player is giving after /vw command. If the player doesnt type the parameter he will recieve this message that he has to type a parameter.

pawn Code:

else
{
new str[256];
SetPlayerVirtualWorld(playerid,virtualworld);
format(str,sizeof(str),"You are now in virtual world %d",virtualworld);
SendClientMessage(playerid,-1,str);
}

If the player has specified a parameter it will go to the next part of code ie after else part this part sets the virtualworld of player by using SetPlayerVirtualWorld function.
We have also made a new variable str.
Here we are using format function because SendClientMessage does not support use of %d, %s etc.The format function is using str variable.
Then we are using SendClientMessage to tell the player that he is now in the virtualworld he specified as a parameter.

pawn Code:

return 1;
}

This tells the work of the code is over.



Please dont be harsh as this is my first post..
Also sorry for my bad grammar
