I'll explain to you the very basics, this is without saving it to a file.

On top of your script add:

pawn Код:

new AdminLevel[MAX_PLAYERS];

This is the variable we are going to store your admin level in.

Then you need to make a command to set the admin level.

pawn Код:

if (strcmp("/password", cmdtext, true) == 0)
        {
            AdminLevel[playerid] = 5;
            return 1;
        }

This command makes the person that types, "/password", a level 5 admin.
Change "password", to a password of your choice.

And that's it. I wont go into creating commands like "/kick", and "/ban", you will need to search for a proper tutorial, there are hundreds in the tutorial section.
