v3.0.9a Update (06-04-2018)Edit

Hi all,

We've released a small, yet important update to ZPS version 3.0.9!

This patch includes a few changes to the round manager regarding a zombie skipping bug, sound tweaks, and Asylum bug fixes. Full details on the list below!

v3.0.9a ChangelogEdit

General

  • Added "changelevel" as an alias to "map" in the admin built-in system.
  • Added "sv_punish_late_joining_abuse" CVAR for server operators to control the anti-late joining abuse system (by community request).
  • Added "sv_punish_starting_zombies_skipping" CVAR for server operators to control the anti-starting zombies skipping/anti-zombies rage quit system (by community request).
  • Fixed an issue where kicked players wouldn't drop their inventory (could be used for griefing).
  • Fixed a security flaw where it was possible to crash a server by cooking a grenade and dying (thanks [ZB] Winter).
  • Fixed delivery/useable items being useable through world brushes.
  • Fixed zombies being able to respawn infinitely even if all zombies lives are used.
  • Made the "Allow servers to open web MOTD in Steam Overlay" CVAR disabled by default.
  • MP3 player can be localized.

Maps

  • zpo_frozenheart
    • Fixed broken C4 teleporter.
  • zps_asylum
    • Added cubemaps.
    • Fixed player clipping
    • Fixed misaligned decal
  • zpo_harvest
    • Fixed broken z-spawn
    • Grammar fix in game_text
  • zpo_biotec
    • Key protection
    • Fixed a broken z-spawn

Music engine (backported from v3.1)

  • Added ID3v1 tag parsing capability to retrieve the music's title directly from the file instead from a hardcoded list.
  • Replaced obsolete FMODEx middleware to the latest FMOD Studio Low Level API with a lot of bug fixes, speed improvements, security fixes.
  • [Community request] Server operators can now make a "HTTP/HTTPS jukebox" system with Angelscript/SourceMod, see this guide for details. Players will be required to enable the system through ZP Options in order to make it work.
  • No longer relies on a hardcoded list, this makes adding custom and replacing existing musics easier, check the Steam guide for more information.

Changes for moddersEdit

  • Level Designers - Since delivery/useable items are no longer useable through the world, you need to make sure that your "trigger_useable" brush does NOT collide with anything.
  • Music - Because the music engine has been changed, music mods will have to be updated, please read this guide for details.

v3.0.9 Update (05-16-2018)Edit

Hey everyone,

Remember when we said v3.0.8 would be the last? Yeah, we lied. Sorry! We've updated ZPS to version v3.0.9!

This is an important update because it features changes to the rounds manager where late joiners won't be able to play as a Survivor every time, a penalty for players who choose to 'zombie skip' during the round, small changes to ZP Options, tweaks to pistol fire rate and more.

We also have slightly increased movement speed for regular zombies! Check the list below for full details:

v3.0.9 ChangelogEdit

General

  • Added a "Game Manual" button that opens the Steam overlay to our official ZPS manual. (Special Thanks to: Orphanage and the dev team)
  • Updated English and French translations.

Code

  • Angelscript - Added "CHL2MP_Player.OpenSteamOverlayToWebPage( const string& in szURL )" function (clients can deny it's execution, see below).
  • Round Manager - Fixed an exploit where players could bypass starting zombie selection and late joining.
  • Round Manager - Late joining as a survivor is now limited at "once per map" to prevent abuse.
  • Round Manager - Players that try to bypass the new late joining limitation are punished by being forced to play as a zombie.
  • Round Manager - Players that try to zombie skip are punished by being forced to play as a zombie.
  • Round Manager - Starting zombies that tries to zombie skip are forced back in the zombie team as punishment.
  • Server configuration - Added "sv_allow_wait_command 0" to the default server configuration in an attempt to block fast pistol firing scripts.
  • ZP Options - Added a tab for custom content settings.
  • ZP Options - Clients can control if servers can open their Steam overlay to web pages (see Angelscript function above).
  • ZP Options - Move "Disable player sprays" option from the misc tab to the custom content one.

UI

  • Added animations to the zombie lives counter for consistency with the rest of the HUD.
  • Added a warning threshold to zombie lives counter (will flash red if zombies are almost out of lives).
  • Health is no longer considered critical below 20 (HL2's value), it is now considered critical below 35 if you are a survivor and 80 as a zombie.

Maps

  • zps_sapidcerebrum
    • Fixed basement trap's door elevator.
    • Fixed Zombie ladder at the light booth.

Weapons

  • Fixed golf club dealing more damage on the stomach/chest rather than the head.
  • Decreased pistols firing rate, the time between 2 shots has been changed from 0,11 seconds to 0,13 seconds.

Zombies

  • Increased movement speed for regular zombies 140 to 145.

Server owners are required to update their server as soon as possible - also be sure to backup your server.cfg file. Steam will automatically update your client shortly.

v3.0.7-Hotfix3 is live! (12-03-2018)Edit

We are shipping a very important hotfix for v3.0.7 that addresses newfound critical security exploits that could crash dedicated servers.

Servers operators are required to update their servers as soon as possible. Steam will automatically update your client shortly.

ChangelogEdit

Code

  • Add "player is not alive" checks when performing client commands such as panicking, dropping ammo, changing ammo drop type, etc.
  • Fixed the "drop ammo when the round is starting infinite loop" glitch that would freeze servers.

zps_town

  • Fixed visible NODRAW textures.

Reverting to 3.0.6 (01-02-2018)Edit

Due to the many new issues caused by the v3.0.7 update, we've had to revert to v3.0.6 for the time being until these issues are properly fixed. We're very sorry for the inconvenience that the v3.0.7 update has caused, and we appreciate your patience while we resolve these issues.

What about v3.0.7?Edit

We're currently working on yet another overhaul to the code in order to fix the issues with v3.0.7, as well as (hopefully) some of the other issues that we've been unable to fix in the last few patches.

We estimate that this will likely take around 3 weeks, but this is just an estimate. It could end up taking longer than that, since we're basically starting from scratch again with a fresh code base and leaving the HL2MP portion untouched this time.

AchievementsEdit

This revert will cause all map related achievements to be unobtainable during this time.

The reason for this is because we're reverting the binaries (client.dll and server.dll), but keeping the map updates. Since those map achievements have been changed to function differently in v3.0.7, they'll no longer work properly with this revert to v3.0.6.

This sucks, we know - but it's much better than dealing with all the new glitches that popped up. You'll be able to get these achievements again once we release v3.0.8.
