SendProxy Manager
 
SendProxy Manager

SendVar Proxies allow you to send netprop values to clients without actually changing them on the server. If you've coded with SDKHooks before, this should be easy to use, as I designed it to be very similar to SDKHooks. This extension only works on and is only supported on the following engines: ep2, ep2v, and css.

Download (1.1.3): removed
or view the source removed

Here's some example code to get you started.

PHP Code:
#include <sourcemod>
#include <sendproxy>

public OnPluginStart()
{
    RegConsoleCmd("test_hook", Command_TestHook);
}

public Action:Command_TestHook(client, args)
{
    SendProxy_Hook(client, "m_iTeamNum", Prop_Int, ProxyCallback);
    return Plugin_Handled;
}

public Action:ProxyCallback(entity, const String:propname[], &iValue, element)
{
    //Set iValue to whatever you want to send to clients
    iValue = 3;
    return Plugin_Changed;
} 
The proxy callback prototype varies for the type of prop you are proxying:
PHP Code:
funcenum SendProxyCallback
{
    Action:public(entity, const String:PropName[], &iValue, element), //Prop_Int
    Action:public(entity, const String:PropName[], &Float:flValue, element), //Prop_Float
    Action:public(entity, const String:PropName[], String:modifiedValue[4096], element), //Prop_String
    Action:public(entity, const String:PropName[], Float:vecValues[3], element), //Prop_Vector
}; 
The currently supported types are:
Code:
enum SendPropType {
    Prop_Int = 0,
    Prop_Float = 1,
    Prop_String = 2,
    //Prop_Array = 3, //Don't use yet, not fully implemented
    Prop_Vector = 4,
    Prop_Max
};
If you return Plugin_Changed in a callback, the extension will mark the edict as changed to avoid console spam from the engine. The actual values of the prop are passed through iValue, flValue, modifiedValue, and vecValues, which you can change as you see fit.

If you manage to crash this, please do provide me with some debug data and the source to whatever crashed it so that I may fix said crash as quickly as possible.

While I'm not completely sure, I think you can detect the "Shoot on Crits" hack(s) with this by hooking the prop (I could also be insane). This has so many use cases it isn't even funny.

Fixed your error (Could not find prop m_iHealth in sendtable DT_CSPlayer) hopefully. It now searches all datatables within datatables for the prop you want. Redownload for the updated version.

Also it handles client disconnects now, so you don't need to manually unhook it for client disconnects.

Updated (1.0.3).

The integer and float SendProp values are now passed through iValue and flValue in the callback.

Re: SendProxy Manager
 
This was compiled against SM 1.4
It will not work on 1.3
1.3 is almost out the window, with 1.4 almost released.
Upgrade to 1.4
kthx

Look under the development branch. Select the most recent release for the OS your sever runs.

It allows you to use sendproxies in pawn. How useful it is, that is up to the people developing plugins that use it.

That's a good idea. You could even send fake crit prediction "notices" to test clients that are only attacking during those times.

Unfortunately I haven't played enough TF2 (5 mins total) to know enough about the game to work on something like that. Eventually though!

I would really like to see this be able to choose which clients receive the modified SendProp. I did a little peeking and you can set the DataTable proxy function and modify the recipients but that will probably block the table getting sent to all the clients. Good work regardless Afronanny.

I've been trying to do this for months. Entities are only packed for transmission once per tick, and there's only one frame snapshot for all clients.

The Source engine just doesn't support sending different netprop values to different clients. It's possible to hack around it, but it would be a CPU-intensive, memory-hogging mess of a plugin that would have to detour just about every function that had a CFrameSnapshot* in its calling parameters and would be responsible for keeping track of and populating a CFrameSnapshot for every client for every tick.

The only other way I can think of is to play with packets as they're being sent, which would probably be the easiest solution, but not if you want an easy API that can send any netprop value to any client. You'd have to know which netprop you want to change, which packet the entity is being transmitted to the client in, and exactly where in the packet that netprop value is. So that isn't the best solution either.

I'll keep trying, but I have little hope that this will work. (Maybe Valve will add this feature in the future. Imagine the endless new plugin possibilities that this feature would bring!)

Re: SendProxy Manager
 
Seems very interesting. Can someone spitball some ideas about how this would be used? Why would you want to change the client netprops but not on the server?

Thrawn2 10-27-2011 12:26
Re: SendProxy Manager
 
basically the server calculates with the original values while the clients see faked ones instead.

i didn't test any of those:
make all players think a player is low at health, but really has like 5000.
make a player seem like he's on team blue but he really is red and therefore takes damage inflicted by his seemingly blue teammates.
give a player the uberglow without being ubered and still taking damage.
move entities without moving them.

Re: SendProxy Manager
 
I think I did something wrong in string/array proxying. Once I get back to a Windows computer I'll be able to get fixes for that compiled and pushed out.

For example right now the m_glow netprops in L4D2 is send to all players with no way to tell the game who should see the glow and who should not.

With this extension I can send glows only to 1 person or only to the infected team.

No you can't. Proxies are called once for all players per tick. As I mentioned above, you cannot send a modified value to only one client.

So for example you could make it appear that your character is sitting in one spot but be in another? lol.

Re: SendProxy Manager
 
Any chance of getting array support? I'd like to do something like this:

Code:
CCSPlayerResource:
 Sub-Class Table (1 Deep): DT_CSPlayerResource
  Sub-Class Table (2 Deep): DT_PlayerResource
  Sub-Class Table (3 Deep): m_iPing
  -Member: 000 (offset 0) (type integer) (bits 10)
  -Member: 001 (offset 4) (type integer) (bits 10)
  -Member: 002 (offset 8) (type integer) (bits 10)
  -Member: 003 (offset 12) (type integer) (bits 10)
  -Member: 004 (offset 16) (type integer) (bits 10)
  -Member: 005 (offset 20) (type integer) (bits 10)
... etc ...
Code:
public OnMapStart()
{
    new ent = FindEntityByClassname(MaxClients + 1, "cs_player_manager");
    SendProxy_Hook(ent, "m_iPing", Prop_Array, ProxyCallback);
}

I'll have to think about the best way to implement this, seeing as array members can consist of any of the other types. Additionally, what if you only wanted to proxy one of the array members?

I shall ponder this and try some things.
