Can't seem to find any credits anywhere so I'll link the base ESP plugin you used:

What's with the command name?
PHP Code:
RegConsoleCmd("sm_1xlantewallhackespwallhackjoulax1", Command_ESP);
FakeClientCommand(i, "sm_1xlantewallhackespwallhackjoulax1");
If I'm not mistaken any player can use sm_searchcmd and find the command to use on themselves.
Instead of FakeClientCommand you can simply use Command_ESP on the target.
