Hi,

please, see comments at the end of code:

#define PLUGIN_VERSION "1.0"

#pragma semicolon 1
#pragma newdecls required

#include <sourcemod>

public Plugin myinfo =
{
	name = "Block3person",

	description = "Forbid players to use 3-rd person view",
	version = PLUGIN_VERSION,
	url = "https://github.com/dragokas"
}

Handle g_hCvar3PersonView;

public APLRes AskPluginLoad2(Handle myself, bool late, char[] error, int err_max)
{
	char sGameName[12];
	GetGameFolderName(sGameName, sizeof(sGameName));
	if( strcmp(sGameName, "left4dead", false) )
	{
		strcopy(error, err_max, "Plugin only supports Left 4 Dead 1.");
		return APLRes_SilentFailure;
	}
	return APLRes_Success;
}

public void OnPluginStart()
{
	g_hCvar3PersonView = CreateConVar("c_thirdpersonshoulder", "0", "3-rd person view mode", FCVAR_REPLICATED);

	CreateTimer(1.1, Timer_CheckClientViewState, _, TIMER_REPEAT|TIMER_FLAG_NO_MAPCHANGE);
}

public Action Timer_CheckClientViewState(Handle timer)
{
	for (int i = 1; i <= MaxClients; i++)
	{
		if(IsClientInGame(i) && GetClientTeam(i) == 2 && !IsFakeClient(i) && IsPlayerAlive(i))
			QueryClientConVar(i, "c_thirdpersonshoulder", QueryClientConVarCallback);
	}
	return Plugin_Continue;
}

public void QueryClientConVarCallback(QueryCookie cookie, int client, ConVarQueryResult result, const char[] sCvarName, const char[] bCvarValue)
{
	if (StringToInt(bCvarValue) != 0)
		CreateTimer(0.2, Timer_ChangePersonView, GetClientUserId(client), TIMER_FLAG_NO_MAPCHANGE);
}

public Action Timer_ChangePersonView(Handle timer, int UserId)
{
	SetFirstPersonView(UserId);
}

void SetFirstPersonView(int UserId)
{
	int client = GetClientOfUserId(UserId);
	
	if (client == 0 || !IsClientInGame(client))
		return;
	
	PrintToChat(client, "changing the state");
	
//  L4d2 only
//	SetEntPropFloat(client, Prop_Send, "m_TimeForceExternalView", 0.0);

//  Server say: can't change because not marked as FCVAR_REPLICATED on client side
//	SendConVarValue(client, g_hCvar3PersonView, "0"); 

//  Also not working
//	FakeClientCommand(client, "thirdpersonshoulder");
}

Thanks.

Aren't firstperson and thirdpersonshoulder client-side commands? If so, you can't force them on clients.

I don't know if AddCommandListener() would work for detecting the use of thirdpersonshoulder though.

About: SetEntPropFloat
In L4D2 it is working, but L4D1 has no such property.

It seems you are right.

public void OnPluginStart()
{
	AddCommandListener(Listener_3Person, "thirdpersonshoulder");
}

public Action Listener_3Person(int client, const char[] command, int argc)
{
	PrintToChat(client, "thirdpersonshoulder is intercepted.");
	return Plugin_Stop;
}

No, callback is not called. Quite expected, considering that it's client side command.
Any another ideas to block 3-rd person view?

PHP Code:

public void OnPluginStart()
{
    AddCommandListener(BlockCommand, "thirdpersonshoulder"); 
}
public Action BlockCommand(int client, char [] command, int args) 
{
    return Plugin_Handled; 
} 


[Dragokas]

you mean Plugin_Handled, not Plugin_Stop ?
I read Plugin_Stop can be used in this doc.

Anyway, callback is not called, so no matter.

Here you go guys. I tested this and it works.

NOTE: If you're hosting via a listen/local server, the ReplyToCommand() message will display on the console instead of chat because you are counted as client 0. I tried adding a check but it didn't work. I also tried using PrintToChat() but it doesn't work for client 0 either, even with my bIsValidClient() check.

PHP Code:

#include <sourcemod>
#pragma semicolon 1
#pragma newdecls required
#define TPSB_VERSION "1.0"

ConVar cvAllowAdmins;
ConVar cvEnablePlugin;

public Plugin myinfo =
{
    name = "Thirdpersonshoulder Blocker",
    author = "Psykotik (Crasher_3637)",
    description = "Blocks thirdpersonshoulder.",
    version = TPSB_VERSION,
    url = "https://forums.alliedmods.net/showthread.php?t=307099"
};

public void OnPluginStart()
{
    cvAllowAdmins = CreateConVar("tpsb_allowadmins", "1", "Allow admins to use thirdpersonshoulder?\n(0: OFF)\n(1: ON)");
    cvEnablePlugin = CreateConVar("tpsb_enableplugin", "1", "Enable the Thirdpersonshoulder Blocker?\n(0: OFF)\n(1: ON)");
    CreateConVar("tpsb_pluginversion", TPSB_VERSION, "Thirdpersonshoulder Blocker version");
    AddCommandListener(cmdTPSB, "thirdpersonshoulder");
    AutoExecConfig(true, "thirdpersonshoulder_blocker");
}

public Action cmdTPSB(int client, char[] command, int args)
{
    if (cvEnablePlugin.BoolValue && (!cvAllowAdmins.BoolValue || (cvAllowAdmins.BoolValue && !bIsAdminAllowed(client))))
    {
        ReplyToCommand(client, "[TPSB] The \"thirdpersonshoulder\" command has been blocked on this server.");
        return Plugin_Handled;
    }

    return Plugin_Changed;
}

bool bIsAdminAllowed(int client)
{
    return (CheckCommandAccess(client, "tpsb_override", false));
}

Thanks for code

Hi, Crasher_3637. As I said before AddCommandListener callback is not called for me.
I don't know what environment you tested it.
I have 2 coop servers with SM 1.9.0.6226. Your plugin loaded successfully but not work.

Anyway, thanks for try.
