[L4D2] Versus Water Brake

For some reason Valve decided to all but remove the slowdown of Water on Survivors, in Versus Modes. Hard Rain Maps 3 and 4 are pretty much jokes because of this.

Also adds depth to Swamp Fever. :D

This Plugin gives you the power to bring back the slowdown.

Active in configurable gamemodes

CVARS:

l4d2_vswaterbrake_enabled (default 1) - 0 disabled it

l4d2_vswaterbrake_slow (default 0.7) - How much slower will a Survivor be in water - 0.75 equals 75% speed

l4d2_vswaterbrake_jockeyslow (default 0) - Will a Jockeyed Survivor be slowed down still?

l4d2_vswaterbrake_at_low_health (default 0) - Will a limping Survivor be slowed down?

l4d2_vswaterbrake_gamemodeactive (default "versus,teamversus,scavenge,teamscavenge,muta tion12,mutation13") - which gamemodes will the water brake work in

Changelog:

1.0.0 - Release
1.0.1 - Moar Performance
1.0.2 - Bunny Hopping Fix
1.0.3 - fix for Mapchange errorlogs
1.0.4 - introduced Jockey Slow cvar
1.0.5 - fixes for localhosts or 0 Survivor case
1.0.6 - IsValidEntity check against errorlogs added.
1.1.0 - updated to have the same functionality the srsmod submodule has
1.1.1 - added active gamemode convar

Re: [L4D2] Versus Water Break

awesome stuff. those maps are definitely jokes now. i'll be putting this in right away.

Re: [L4D2] Versus Water Break

Awesome! Does anyone know how much the water slows you down in CoOp?

Re: [L4D2] Versus Water Break

Atomic you rock man.
I know the pubs are going to rage so much when I start using this tonight!! xD
It would be so cruel to set 100% slow down... so they just get stuck :P

I included Frameskips and made it as easy to run as possible. Im quite certain you could run 100 instances of the plugin without slowing a server down :grrr:

Re: [L4D2] Versus Water Break

Been waiting for this one. Thanks, makes Hard Rain well hard again.

Edit: Tested the plugin at 50% it felt just like co-op but it would be nice to have the exact number co-op is at.

Edit2: Ok bit of a problem with bunny-hopping, don't know if it can be fixed. In co-op you bunny-hop in the water it still feels slow, but using this plugin it feels like you accelerate though the air. You can just bunny-hop and avoid the slow down effect all together. Now I doubt most people will pick this up but me and my friends played defrag on quake3 forever and the minute they jump(and feel that acceleration like I did) they'll bunny-hop the whole thing.

Well I am going to assume it's just not possible to do this without OnGameFrame. That being said your OnGameFrame has a lot of redundant checks.

PHP Code:


		
			
            if (!IsClientInGame(target)) continue;

            if (GetClientTeam(target) != 2) continue;

            if (!IsPlayerAlive(target)) continue;

It loops from 1,MaxClients every time and skips all the "invalid" clients. However if we consider the typical situation of 4 alive survivors, 18 maxclients, that means you're skipping 66.66% of the time. Plus calling extra natives which is relatively expensive.

By doing something like this you can reclaim a 66% speedup.

PHP Code:


		
			
#define MAX_SUPPORTED_CLIENTS 32

new survivor_clients[MAX_SUPPORTED_CLIENTS];

new survivor_count = 0;



FindSurvivorIdx(client)

{ 

  for(new i = 0; i < survivor_count; ++i) 

    if(survivor_clients[i] == client) return i;

  return 0;

}



SwapArrayElements(array[], a, b)

{

  if(a == b) return;

  new tmp = array[a];

  array[a] = array[b];

  array[b] = tmp;

}



//call this when player connects AND hes a survivor AND hes alive

OnPlayerJoinSurvivors(client)

{

  if(!FindSurvivorIdx(client))

    survivor_clients[survivor_count++] = client;

}



//call this when a player disconnects OR hes not a survivor OR hes not alive

OnPlayerLeaveSurvivors(client)

{

  new idx = FindSurvivorIdx(client);

  //keep the array contiguous

  if(idx) 

  {

    SwapArrayElements(survivor_clients, idx, survivor_count-1);

    survivor_count--;

  }

}



////////////



public OnGameFrame()

{

  //early out checks as before

  for(new idx = 0; idx < survivor_count; i++)

  {

    new target = survivor_clients[idx];

    

    new level = GetEntData(target, WaterOffset, 1);

    // etc rest of this is the same as before

  }

}

I used it in Hard Rain tonight. It worked like a charm.
