Vanish hooks

[IIIaKa]

As we already know, in the December update, the developers added a new command "invis"(Vanish).
I suggest adding OnVanishDisappear and OnVanishReappear hooks to track the entry and exit from invisibility, similar to what is already available in the Vanish and BetterVanish plugins.

1. The OnVanishDisappear hook is called after the player became invisible. No return behavior.

void OnVanishDisappear(BasePlayer player)
{
    Puts($"Player {player.displayName} has become invisible.");
}

2. The OnVanishReappear hook is called after the player became visible. No return behavior.

void OnVanishReappear(BasePlayer player)
{
    Puts($"Player {player.displayName} is visible again.");
}

Code before:

[ServerVar(Help = "Make admin invisibile")]
public static void invis(ConsoleSystem.Arg arg)
{
	global::BasePlayer basePlayer = arg.Player();
	if (basePlayer == null)
	{
		return;
	}
	bool @bool = arg.GetBool(0, !Debugging.invisiblePlayers.Contains(basePlayer));
	if (@bool && !Debugging.invisiblePlayers.Contains(basePlayer))
	{
		Debugging.invisiblePlayers.Add(basePlayer);
		basePlayer.limitNetworking = true;
		basePlayer.syncPosition = false;
		global::HeldEntity expr_5D = basePlayer.GetHeldEntity();
		if (expr_5D != null)
		{
			expr_5D.SetHeld(false);
		}
		basePlayer.DisablePlayerCollider();
		Rust.Ai.SimpleAIMemory.AddIgnorePlayer(basePlayer);
		global::BaseEntity.Query.Server.RemovePlayer(basePlayer);
		if (!Global.Runner.IsInvoking(new Action(Debugging.TickInvis)))
		{
			Global.Runner.InvokeRepeating(new Action(Debugging.TickInvis), 0f, 0f);
		}
	}
	else if (!@bool && Debugging.invisiblePlayers.Contains(basePlayer))
	{
		Debugging.invisiblePlayers.Remove(basePlayer);
		basePlayer.limitNetworking = false;
		basePlayer.syncPosition = true;
		basePlayer.EnablePlayerCollider();
		Rust.Ai.SimpleAIMemory.RemoveIgnorePlayer(basePlayer);
		global::BaseEntity.Query.Server.RemovePlayer(basePlayer);
		global::BaseEntity.Query.Server.AddPlayer(basePlayer);
		if (Debugging.invisiblePlayers.Count == 0)
		{
			Global.Runner.CancelInvoke(new Action(Debugging.TickInvis));
		}
	}
	arg.ReplyWith("Invis: " + basePlayer.limitNetworking.ToString());
}

Code after:

[ServerVar(Help = "Make admin invisibile")]
public static void invis(ConsoleSystem.Arg arg)
{
	global::BasePlayer basePlayer = arg.Player();
	if (basePlayer == null)
	{
		return;
	}
	bool @bool = arg.GetBool(0, !Debugging.invisiblePlayers.Contains(basePlayer));
	if (@bool && !Debugging.invisiblePlayers.Contains(basePlayer))
	{
		Debugging.invisiblePlayers.Add(basePlayer);
		basePlayer.limitNetworking = true;
		basePlayer.syncPosition = false;
		global::HeldEntity expr_5D = basePlayer.GetHeldEntity();
		if (expr_5D != null)
		{
			expr_5D.SetHeld(false);
		}
		basePlayer.DisablePlayerCollider();
		Rust.Ai.SimpleAIMemory.AddIgnorePlayer(basePlayer);
		global::BaseEntity.Query.Server.RemovePlayer(basePlayer);
		Interface.CallHook("OnVanishDisappear", basePlayer);//<=== OnVanishDisappear
		if (!Global.Runner.IsInvoking(new Action(Debugging.TickInvis)))
		{
			Global.Runner.InvokeRepeating(new Action(Debugging.TickInvis), 0f, 0f);
		}
	}
	else if (!@bool && Debugging.invisiblePlayers.Contains(basePlayer))
	{
		Debugging.invisiblePlayers.Remove(basePlayer);
		basePlayer.limitNetworking = false;
		basePlayer.syncPosition = true;
		basePlayer.EnablePlayerCollider();
		Rust.Ai.SimpleAIMemory.RemoveIgnorePlayer(basePlayer);
		global::BaseEntity.Query.Server.RemovePlayer(basePlayer);
		global::BaseEntity.Query.Server.AddPlayer(basePlayer);
		Interface.CallHook("OnVanishReappear", basePlayer);//<=== OnVanishReappear
		if (Debugging.invisiblePlayers.Count == 0)
		{
			Global.Runner.CancelInvoke(new Action(Debugging.TickInvis));
		}
	}
	arg.ReplyWith("Invis: " + basePlayer.limitNetworking.ToString());
