When a player writes /invis enemy players to be hidden and when it's written again to become visible once again.

[Lolz0r]

Not working, message is displayed, but they not were hidden.

[drekes]

It works now.

[Lolz0r]

Yes, it's work, maybe could make a version for team players not enemy, and verison for all playes?

[drekes]

Do you want that to be individual per player or with a cvar for all of them ?

[Lolz0r]

Individuals versions for all players and team players hidden.

[drekes]

Edited code above.

You can change the way it works with this define:

/*	Hiding Options
	0 = All Players
	1 = Teammates
	2 = Enemy Players
*/
#define Hide_Option	0

[Lolz0r]

Maybe could do with cvar?

[Exolent[jNr]]

PHP Code:

    static szPlayers[20];
    if(!szPlayers[0])
#if Hide_Option == 0
        copy(szPlayers, charsmax(szPlayers), "All players");
#endif
#if Hide_Option == 1
        copy(szPlayers, charsmax(szPlayers), "Teammates");
#endif
#if Hide_Option == 2
        copy(szPlayers, charsmax(szPlayers), "Enemy players");
#endif 


1. There's no point in making it static inside of a command handler since it isn't called often enough to need that.
2. You can just declare it as a constant (whether static or not) to save a native call.

#if Hide_Option == 1
    new const szPlayers[] = "Teammates";
#else
#if Hide_Option == 2
    new const szPlayers[] = "Enemy players";
#else
    new const szPlayers[] = "All players";
#endif // Hide_Option == 2
#endif // Hide_Option == 1
