    Allows slowing down Survivors in Water for Versus

    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.

    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

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

    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

    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 
    0survivor_count; ++i
        if(
    survivor_clients[i] == client) return i;
      return 
    0;
    }

    SwapArrayElements(array[], ab)
    {
      if(
    == 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_clientsidxsurvivor_count-1);
        
    survivor_count--;
      }
    }

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

    public OnGameFrame()
    {
      
    //early out checks as before
      
    for(new idx 0idx survivor_counti++)
      {
        new 
    target survivor_clients[idx];
        
        new 
    level GetEntData(targetWaterOffset1);
        
    // etc rest of this is the same as before
      
    }
