v3.1.1 Update and Custom Content Notice



We've released the first patch to Zombie Panic! Source v3.1 that addresses major bugs, game balance issues and minor changes reported recently in both Discord and Steam forums. We also want to leave an important note to all server owners and Workshop map authors in this announcement.

[h2]Notice to Server Operators and Workshop Authors[/h2]
Along with fixes to Workshop mounting for Dedicated servers, we've updated our requirements for map authors and now request that they add and/or update their Workshop item with a text file called "addoninfo.txt" in the root folder of your map. If you already have this file in your Workshop item, be sure to update your text file with the following line: "type" "map". For example:
"AddonInfo"
{
	"title"					"My Map"
	"description"			"This is my first map for Zombie Panic! Source."
	"version"				"1.0"
	"author"				"John Doe"
	"authorSteamID64"		"76500000000000000"
	"type"				"map"
}

This is an important update for all authors who have previously uploaded a Workshop map. You can find more information about uploading custom content to the Workshop in our community guide.

Server owners who utilize the Workshop collection can manually edit and update this text file @ "\\zps_custom\\workshop\\content\\17500" as a temporary fix. A reminder that they have to mount the Workshop item as well in "zps\\addons\\addonlist.txt", here's an example for Anoxia (workshop ID = 974503415) and Area 41 (workshop ID = 1068697639):
"AddonList"
{
	"974503415"	"1"
	"1068697639"	"1"
}

With that out of the way, let's dive into the changelog of today's patch.

Update Notes

[h3]Angelscript[/h3]
Added "int Utils.GetNumGamePlayers( bool bAlive )". Returns the number of players in the Survivor and Zombie teams which is more efficient than doing "Utils.GetNumPlayers( survivor, false/true ) + Utils.GetNumPlayers( zombie, false/true )"

Fixed missing "new line" characters in several log messages.
Renamed the chat broadcaster, rock the vote and spray checker plugins files to lowercase for Linux

[GAMEBREAKING] Added missing exclamation mark for 'You are awesome' voice line.
Changed lookup path of custom content outside of the Steam Workshop from "zps_custom" to "zps/custom".
Changed the behavior of "sv_zps_vote_adminonly_votes". If enabled, only admins can use "callvote".
Disabled Vanessa's gibs and LOD models as an attempt to temporally fix a client crash for some people running on low game settings.
Upgraded game engine to the latest public version of Source SDK Base 2013 Multiplayer.
Fixed "custom_map" Steam Rich Presence being shown when playing on custom maps.
Fixed a rare case of players being unable to launch the game.
Removed VR strings leftovers within the code and game start up.
Removed many old unused characters textures from VPKs.

[h3]Generic[/h3]
Made the following methods in "CZP_Player" virtual so that they can be used in SourceMod; const char *GetModelString() --- Returns the name of the character this client is playing ("eugene", "marcus"...)
const char *GrabTeamSpawn() --- Returns the class name of the spawn entity that concerns this client's team ("info_player_human" if you are on the Survivor team)
bool IsAwayFromKeyboard() --- Returns true if AFK checker considers this client as being AFK this simulation frame
bool IsCarrier() --- Explicit
bool IsInfected() --- Explicit
bool IsInfectionKnown() --- Returns true if the client is infected and knows about it (HUD icon changed, heartbeat sound)
bool IsOnATeam() --- Returns true if the client is not in the unassigned/lobby teams
bool IsRoaring() --- Explicit
void SetCarrier( bool value ) --- Explicit
void SetInfectionResistance( int percentage, float time ) --- Set the infection resistance chance and time (aka green inoculator effect) for this client, "percentage" is a value between 0 and 100, "time" is in seconds
void SetInfection( bool infect, bool forced, int time ) --- Set the infection state for this client, "forced" is set to true when a Survivor is infected because "not enough Zombies due to ragequit/kick and so on". Leave it to "false" to simulate a "normal Carrier" infection. "time" is in seconds.

Speaking of SourceMod, thanks to community member Silence, the "gamedata offsets/signatures" have been updated to run on the latest v3.1 update, improving compatibility and stability with SourceMod itself and plugins. You can grab the latest stable build here.

[h3]Linux[/h3]
Replace Source SDK Base 2013 Multiplayer's "libtier0.so" and "libvstdlib.so" binaries by symbolic links to their server counterparts. Fixes the missing important game sounds (weapons, footsteps, voices...) not being played (GH-VALVE-SDK2013-PR-448).
Replace Source SDK Base 2013 Multiplayer's "steamclient.so" binary by a recent version from SteamCMD (fixes the dedicated server getting stuck in Workshop downloads)
Shipped a compiled version of OpenSSL compatible with ZPS in an attempt to fix the "could not library" error with some Linux distributions with and without the Steam Runtime. This is not enabled by default to prevent breaking working setups, To use this compiled version of OpenSSL, add the "-linux-extra-bins" parameter to the command-line launch options.
[Update 10/26] Fixed a starting issue about the newly added "-linux-extra-bins" command-line argument.

[h3]Maps[/h3]
Aquatica (Objective) - Increased ammo count on high player count and re-scaled supplies distribution.
Asylum (Survival) - Fixed props outside of the map and optimized displacements.
Blackout (Survival) - Fixed few texture issues and updated ammo spawns.
Cinema (Survival) - Fixed a glitch spot on Cinema 1 with a player clip.
Corpsington (Objective) - Increased ammo count on high player count.
Corpsington (Survival) - Fixed some player clipping issues.
Deadend (Survival) - Added player clip on the door and the roof between cemetery and church.

Murskville (Objective) - Fixed double doors making the players stuck in the check-in room.
Sapidcerebrum (Survival) - Fixed visible NODRAW face and breakable glass near human spawn.
Subway (Objective) - Re-scaled supplies distribution.
Zomboeing (Objective) - Fixed areaportals leaking through the door.

[h3]Server[/h3]
In order to fix the BZ2/FastDL problem in Dedicated Servers, third-party content had to be moved from zps_custom to zps/custom folder. Servers operators are required use this folder to install new custom content (maps/sounds/materials) outside of the Steam Workshop. For further information regarding this topic, please visit this thread in our forums for details.
If you changed the "zps/data/adminsystem.json" and/or "zps/default_plugins.json" files, make backups before updating your server, we had to change them to fix some issues listed here and SteamCMD might override them.
[h3]UI[/h3]
Added a warning text in "Options -> Video" to warn players to restart their game if they change anything.
Added a text and progress bar indicator whenever a teammate is healing you with an inoculator.
Changed font for game progress HUD (game/round starts in...)
Changed the name of the badge "Mission Commander" to "Commander".
Fixed ESCAPE not cancelling server connection.
Fixed missing HardCore timer on top screen.
Fixed server info dialog having text overlapping issues.
Servers browser will no longer subtract bots from players count.
Servers browser will now show bots on a separate column.

[h3]Weapons[/h3]
Fixed stackable items/weapons (like grenade) not adding/removing weight when many of them were picked up.
Updated grenade throwing animations timing.
Updated carry animation on the fuse and keys item delivery.
Updated inoculator viewmodel animations making it faster to use.
Updated Survivor's hands viewmodel animations and added a "deploy" sequence.
Changed how you cancel reloads and unloads bolt action firearms (Super Shorty and Remington 870). Before you had to hold PRIMARY or SECONDARY ATTACK, now a simple press is enough.

Known Issues
Players running on 2K, 4K or above resolutions are having problems seeing their ammo HUD. Unfortunately, VGUI doesn't really support higher resolutions due being very outdated. A workaround is to use the classic ammo bank HUD by going to: Options > ZP Options > Misc > More > Enable Classic Ammobank. Very few players are experiencing invisible characters in-game for an unknown reason even after a full game nor Steam reinstall. We'll be watching this issue closer here.

There are still more bugs to fix up and we'll continue shipping patches (hotfixes in case of emergency) in the upcoming weeks as quickly as possible.


Lastly, we want to thank everyone who have played the update and shared their feedback in the forums! We really appreciate all the kind words and support you've been giving to us. A lot have quite liked the newest Human & Zombie animations and models from the 'Characters Update' Workshop - all made by our talented community members Mage and Silent.
