Notable features

  • Sven Co-op is now its own independent game distributed on Steam, free of charge.
    • Includes 3 packages: A game package for players, a tool package for dedicated server operators, and an SDK package for content developers.
    • Includes use of the Steam game hub platform and community features. (workshop functionality to be included in a future release)
  • Sven Co-op now uses a customized GoldSrc engine with permission from Valve.
    • Gives us the opportunity to improve upon common limitations in the GoldSrc engine.
    • Maps can now be up to ~1,000x larger! (131,072 units away from position zero instead of just 4,096)
    • Mappers: See the engine changes section for more details and technical information.
  • New build of all Half-Life maps for co-operative play.
    • All maps re-ported from scratch for Sven Co-op from Half-Life: Source.
    • Enabled cross-map inventory.
    • Enabled survival game play mode with checkpoints, so players have to be more careful about staying alive and reviving fallen allies.
    • Many maps have been merged into a single map on a per-chapter basis to reduce map changes.
    • The game play is now much more pure, with no "kill monsters to proceed" gates.
  • New inventory system by using the new entity item_inventory, which is an item that a player holds on to for trigger rules and/or side-effects. Some example possibilities:
    • A key item must be carried by a player to a locked door, rather than it instantly becoming unlocked for rushers to wait by.
    • A bomb defuse kit has to be brought to a bomb to defuse it, or it explodes and you all die.
    • A gas mask can protect a player from nerve gas, but only lasts 2 minutes.
    • Did someone say Capture the Flag??
  • New maps:
    • Black Mesa: Special Tactics Sector
    • Desert Circle
    • Fortified
    • Stadium 4
    • Turret Fortress: Reverse
  • New models for many weapons, ammo, and NPCs.
  • New modifiers/effects that can be applied/removed on players and NPCs via inventory items, and scripts, and custom (scripted) entities:
    • Block use of weapons.
    • Damage modifier.
    • Extra / less time before starting to drown.
    • Friction modifier.
    • Ghost / non-solid.
    • Glow shell.
    • Gravity modifier.
    • Invisibility.
    • Invulnerability.
    • Speed modifier.
  • New observer mode:
    • Standard mode: If no spawn points are available for a player to use they become an observer until a spawn point becomes available.
    • Cyclic mode: Players can only respawn out of observer mode when the map explicitly requests so.
    • Survival game mode places dead players into observer mode until a live player reaches a checkpoint.
  • New preliminary A.I. pathing entities for better control on where NPCs move around a map.
  • New scripting engine using AngelScript:
    • Version 2.30.1 implemented.
    • New entity: trigger_script
    • A map script can be loaded by specifying a file in the map's configuration using key map_script.
    • Scripts can be triggered one off or periodically (thinking).
    • Alternative script files can be used, and shared across maps.
    • Store persistent data reliably with SQLite back-end storage.
    • Entire server modifications can be designed, along with SQLite and MySQL storage for server-specific scripts.
    • New survival game play mode driven by a shared script.
    • Watch out in future change logs as many more updates will come with this!
  • New weapon: Displacer from Opposing Force.
  • Player weapons/ammunition can now be carried across map changes. (if a map wants to do this)

Code changes

Game core

  • Added a more graceful way to close servers when an error occurs, most notably listen servers will return the host player to the main menu rather than terminate the process.
  • Added a spawn flag to func_clip so it can block players from throwing an inventory item through them.
  • Added a spawn flag to trigger_hurt to hurt non-moving NPCs.
  • Added a spawn flag to trigger_repsawn only respawn dead players.
  • Added a spawn flag to trigger_track_goal to prevent the train moving backwards if it can't find a path to direct the train to.
  • Added an optional sound to trigger_track_goal if it can't find a path to direct the train to.
  • Added announcement when a player joins a server (as they enter the world after connecting, not when they start connecting) to match the message when players leave.
  • Added custom amount, recharge time, sounds, and trigger properties to health/HEV chargers.
  • Added custom HUD sprite configurations for weapons.
  • Added custom sound file and sentence properties to buttons, doors, platforms, trains, and track trains.
  • Added custom text options for the buttons via trigger_vote.
  • Added IsNotAmmoItem to weapons so they aren't taken (and removed from the map) for ammo when mp_weaponstay is disabled.
  • Added key to trigger_teleport: "teleport_if_blocked", when enabled the teleporter will send the source entity even if the teleporter exit is blocked.
  • Added key to trigger_teleport: "teleport_ignore_delay", when enabled the teleporter ignores all delays (implicitly sets flag 8,192).
  • Added key to trigger_teleport: "teleport_start_inactive", when enabled the teleporter starts inactive (implicitly sets flag 4,096).
  • Added map configuration and text files to the pre-cache list if they exist, so they will be transferred to clients (this excludes those with the CFG extension as that is a security restriction).
  • Added message box support for non-Windows platforms using SDL, mimicking the Windows button sets and response/event codes.
  • Added missing calls to entity destructor functions for Baby Gargantuas and alien slaves so their effect entities can be cleaned up from an unexpected destruction.
  • Added opaque character drawing to game_text by specifying an alpha value of 1 or higher in either colour keys.
  • Added parameter use type (on/off/set/toggle/kill) and value to cheat command trigger.
  • Added player percentage requirement to trigger_changelevel.
  • Added show HUD info to any entity.
  • Allied NPCs can now not be given a weapon by the map.
  • Changed chat messages from the server console to show the source as Server Console and in orange rather than printing the entire server name.
  • Changed cheat command impulse 101 (giveall) to provide 5 spores instead of 1.
  • Changed command time and timelimit to specify if there is no time limit for the map, and checks map CVAR mp_notimelimit.
  • Changed default map to svencoop1 instead of hldm1 if a map cycle map (or a map cycle file) isn't found.
  • Changed env_sound so that they can be used with brush triggers:
    • Added a spawn flag use only (1) will disable automatic activation based on proximity.
    • When triggered if the radius setting is 0, no radius check will happen and the effect is applied.
    • When triggered if the radius setting is not 0, a radius check will happen so the effect is applied only if the player is within radius.
  • Changed func_tank so it will return to its original orientation when it no longer has any enemies around to fire at.
  • Changed trigger_cdaudio to use an MP3 file rather than try and look for a physical CD.
  • Changed game version mismatch to create a pop-up message and disconnect rather than force the game to quit.
  • Changed maps with player model enforcement to write the player choice model in "cl_model" instead of "team" in the client info string.
  • Changed word executing for parsing when loading skill and static configurations, as these files are not directly executed.
  • Cheat commands that are blocked are now denoted that they were a cheat command in the server log.
  • Disabled map restart when a player respawns whilst CVAR's coop and deathmatch are both disabled.
  • Expanded command myinfo to show your health, maximum health, armor, maximum armor, player state (alive/dead/observer), score, deaths, network defined entity name, game extras level (and optional title), server administrator level, and a count/list of enabled cheats.
  • Expanded command mapinfo to show you the number of entities currently in existence and the number of pre-cached models/sprites (along with their respective limits).
  • Fixed a crash when a map has no configuration file in some cases.

  • Removed border-less window option as SDL handles this now.
  • Removed landmark entity.
  • Removed outdated NOVODEX functionality causing clients to freeze for a while after loading a map.

    • Maximum frame rate: Raised to 200 from 100 (for 120Hz/144Hz monitors). You can still get up to 1,000 frames/second with developer mode enabled.
    • Maximum heap memory size: Raised to 512MB from 128MB.
    • Minimum heap memory size: Raised to 64MB from 14MB.

    • Maximum visibility data: Raised to 64MB from 16MB.
    • Maximum world size: Raised to +/-131,072 from +/-4,096: Only enabled if the game's liblist contains largemap_aware, as the game will need to be built use different data types for handling co-ordinates.

  • Smarter heap memory allocation mechanism:
    • Default heap memory size is now half of all available virtually addressable memory but only up to 512MB from 40MB (for clients) or 32MB (for servers).
    • Default heap memory size will step down by 16MB decrements until enough memory can be allocated by the host system.
    • If the engine can't obtain the minimum required memory from the host system it will refuse to start.
    • Compiled launchers with the large address aware flag so that up to 3GB of memory can be consumed on 32-bit Windows systems (if the /3GB boot switch is used), and up to 4GB on 64-bit Windows systems. Both up from their previous 2GB limit.
    • Launch parameter -heapsize can now be written in MB/GB (i.e. -heapsize 256M or -heapsize 1G).
    • Launch parameter -maxmemory will force the engine to take as much memory as it can from the host system.
    • Launch parameter -minmemory will force the engine to take as little memory as it can from the host system.
    • Launch parameter -showheap will notify you how much memory was successfully allocated from the host system.
    • Stack size increased to 8MB from 1MB.
  • Added addons SteamPipe folder to the default resource search list. Use parameter -noaddons to disable this.
  • Added callback function so the engine can inform the game when a player disconnects.
  • Added graceful shutdown if a BSP failed to load properly.
  • Added interface functions to retrieve the number of pre-cached models and the limit for this for the game library to use.
  • Added mono-spaced font support to the console via CVAR con_mono, enabled by default.
  • Added new key mappings for joystick axis (so analogue L/R triggers can be bound to a command).
  • Added referral address for content downloads over HTTP so web servers can prevent leeching.
  • Added server command logaddress_list to list all current log forwarders (useful for external log managers).
  • Added server CVAR listipcfgfile as a pointer to file listip.cfg, works the same as CVAR bannedcfgfile.
  • Added server CVAR sv_log_daily to enable daily rotation of server log files rather than a new file for every map played.
  • Added support for raw mouse input provided by SDL2.
  • Added wild-card search functionality for entity targets.
  • Changed host error message backwards mins/maxs to include the entity origin and the offending values.
  • Changed the default console position and size so it consumes the right side of the screen with a slight border, similar to that of the Source engine.
  • Changed the snapshot command:
    • Screen shots are now saved in a sub-folder screenshots.
    • File names now include a date stamp YYYY-MM-DD.
    • File names now indexed from 1-9999 instead of 0-1000.
    • Added success message to the console showing you what file name the screen shot got saved as.
  • Console command auto-complete now shows up to 20 entries, and will pop out to the side if it's too long to show below.
  • Console debug log (-condebug) file name is now rotated daily.
  • Fixed a crash if a brush model index is higher than 999 (due to a 4 character limit).
  • Fixed a crash if a camera/viewport is accessed when a player retries connecting to the server.
  • Fixed a crash if an entity doesn't exist while trying to find an attachment point on it.
  • Fixed a crash if an external model/sprite file is missing by replacing it for an ERROR variant with an error about the missing resource written in the console, though a crash will occur if the error replacement is also missing.
  • Fixed a crash if map entity data has a comment between two entities.
  • Fixed a crash when reading a setting from the Windows registry overflows.
  • Fixed a crash when a memory allocation fails (and no indication was given to why the engine crashed).
  • Fixed additive textures on models always rendering with flat shading (causing a low quality look).
  • Fixed alert messages being shown on the client when developer mode is disabled.
  • Fixed chrome textures not scaling up correctly with models, particularly NPCs.
  • Fixed entity collision detection stopping immediately as soon as it finds an entity that should not collide, instead of processing other entities wanting to collide.
  • Fixed empty player authentication ID strings returned whilst the server is shutting down.
  • Fixed model hit boxes not scaling along with a model's physical size.
  • Fixed PAS/PVS not using the player's view origin causing effects/sounds in cameras to not play.
  • Fixed rendering issues when resizing the game window.
  • Fixed servers being able to ban steam ID's VALVE_ID_PENDING and STEAM_ID_PENDING by accident.
  • HUD messages can now be drawn opaquely instead of additive only.
  • Raised HUD text message channels to 8 from 4.
    • The new 4 channels are reserved for map use (via game_text). All existing maps will automatically use these, no updates to maps needed.
    • The first (original) 4 are for internal use by the game engine/library.
