Just set pingfake_flux to something like 5.

Hi,

Would it be possible to add a parameter for minimum/maximum ping? I mean that people whose ping is lower than the cvar wont be faked and people whose ping is higher than the cvar wont be faked.

For example minimum 20 and maximum 50 would mean that if player has a lower ping that 20 it wont be faked and if he has higher than 50 it wont be faked.

This sets the top limit.

Very useful plugin!

Question tho, howcome when I fake someone ping it just stays on the same number. I know pingfake_flux "#" should fix that right? but its not doing anything.

Last version cause many overflows.

10 players in a row get overflowes.


Suck messages i see couple times in every round. All visibled in 1 sec:

PHP Code:

SZ_GetSpace: overflow on Player
SZ_GetSpace: overflow on Player2
SZ_GetSpace: overflow on Player3
WARNING: datagram overflowed for Player

If you have empty server, it could be so.

I have full server.

MeRcyLeZZ, Can you help? Idk why all players have overflows. I just remove trash from plugin...

I only need all players see only 50% of ping. Also I am not sure, what for is "check_for_loaded_pings" function.

I know how to parse all svc_ messages, and ofc added some to wiki.

But i can`t understand how works fix_fake_pings.

register_event("DeathMsg", "fix_fake_pings", "a")
register_event("TeamInfo", "fix_fake_pings", "a")

public fix_fake_pings()
{
......
		fw_UpdateClientData(player)
......
}

public fw_UpdateClientData(id)
{
....
	if (!(pev(id, pev_button) & IN_SCORE) && !(pev(id, pev_oldbuttons) & IN_SCORE))
		return;
...
}

So, when fix_fake_pings triggered, it launch fw_UpdateClientData for all players, but fw_UpdateClientData send messages only for players which "currently" holding IN_SCORE button. So at that time players can see their real ping.

Also right after connect, server send to player svc_pings, so better to add delayed exec with forcing ping. I give advice coz fixed those things in my own plugin that working with ping.

And I see amazing packet calculation

Test code for you, with sending all in one message:

stock send_pings_test(id)
{
	static player;
	static p_ping[33]={0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32};
	static p_loss[33]={0,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132};
	new bb;//byte buffer

	new bits;

	//we should have at least ourself to send ping, or we`ll send empty message and as I suppose get error  :) but never tested that moment
	message_begin(MSG_ONE_UNRELIABLE, SVC_PINGS, _, id);
	for (player = 1; player <= 32; player++)
	{ 
//lets send info about all possible players, even they are not on server
//		if (! g_connected[player] )
//			 continue;
		
		//CAP p_ping p_loss values, if they are too big to send
		if ( p_ping[player] >= (1<<12) )
		{
			p_ping[player] = ((1<<12) - 1 );
		}
		if ( p_loss[player] >= (1<<7) )
		{
			p_loss[player] = ((1<<7) - 1 );
		}

		bb += (1 + ( (player - 1) << 1) + ( p_ping[player] << 6) ) << bits; // (player - 1) coz in that message: message_slot=player_id-1;
		bits += 18;

		for( ;bits >= 8;bits -= 8, bb >>= 8 )
		{
			write_byte( bb ); // or write: bb&((1<<8)-1)
		}

		bb += (p_loss[player] << bits );
		bits += 7;

		for( ;bits >= 8;bits -=8, bb >>= 8 )
		{
			write_byte( bb );
		}
	}

	write_byte( bb ); //write last part or finalize message
	message_end();	
}

Unfortunally we can send that message only with write_byte and in 2 parts otherwise it`s exceed byte buffer size and corrupt it. Or we need to add support of buffer with more than 4 bytes in it.

I tried it and it causes overflows. After a while it will cause channel overflow and everybody on the server will be kicked. No one can't connect after this because it will get kicked again and again untill server restart.
Any fix for this?
