My goal is to have every sven map working for a 1.0 version of this mod. After that, I start trying more of my own ideas, and make guides for others to do the same. There is a lot more you can do with open-source game code.

Most 4.x era Sven Co-op maps work as is. Many 5.x era maps should also work but will need porting if they were compiled with increased limits or use angelscript. The current list of supported maps is here .

A major difference you'll notice is that sven-specific weapons are replaced with stock Half-Life weapons (uzi/saw/minigun/m16 -> mp5, sniper -> crossbow, deagle -> 357). Some basic features are implemented in plugins which haven't been added here yet (player unstucking, thirdperson camera, etc.).

--------------------
Misc
--------------------
investigation notes:
- player name preserved on map change unless downloading files? rename not always shown. also if rejoining name is kept
- mem usage goes up like 4% for each player joined?

hl 25th todo (didn't copy over yet):
- CHalfLifeMultiplay::FShouldSwitchWeapon (cl_autowepswitch) (HLGetNextBestWeapon for singleplayer rules too)
- sv_cheats stuff (i think rehlds handles this?)
- scripted sentence changes for letting buttons or smth speak (scripted.cpp)
- snark anglevectors stuff (what is that for?)
- buster mode + HasPlayerItemFromID

low prio:
- scversion world keyvalue probably affects lots of ents in unknown ways
- thirdperson cancels cutscene
- bounce spam drop weapon on elevator going down
- https://archive.svencoop.com.br/web/svencoop/20230220030651/https://sites.google.com/site/svenmanor/entguide/input_output_ref
- triggers support wildcards (e.g. target = "asdf_*")
- naming a game_end "game_end" prevents it from being triggered
- friendlies not aiming at osprey motors
- env_laser flickering between actual position and 0,0,0 (pointless_b2)
- update reload time to fit weapon animation for custom models
- custom muzzle flashes/events
- show hud what opens doors, what buttons do, etc. (random shitty mapper logic)
- AllocBlock full after 100 map changes or so (client engine problem)
- hornet and shock gun can instant reload by dropping
- why do dead players have better collision than corpse?
- gruntwar floating guns when wall broken
- holding reload on mp5 reloads it twice
- hwgrunt goes idle after a kill and spinning sound stops?
- agrunt custom model without bees trying to shoot bees and not moving? re_evil_directors_cut
- dont allow changing some cvars unless special cases (mp_weaponstay, forcerespawn)
- fall damage for monsters
- getting stuck jumping out of water sometimes
- custom gibs for every monster
- respawn vehicles that leave the map
- try updating richpresence_ vars and scr_connectmsg
- item code duplication (weapons, ammo, items, weaponbox)
- monster code duplication for things like damage and death (basemonster, machines, special monsters)
- physics for sentries
- create a million different idle animations to handle sentences for grunts/otis/etc without precaching?
- turret bezerk death should show skull
- fem assins dont have room to jump away from nade so they flip in-place and go nowhere (sparrows_op_1)
- deluge crossbow not precached -marcu
- pitdrone and gonome also running into wall forever
- displacer portal should have max lifetime (one lost all its velocity and never disappeared`)
- add skill settings for things skill cvar affected

- SV_BuildSoundMsg: scientist/scream07.wav not precached (running away)
- bees can glitch through solids sometimes? (sc_frogger_final bees killing turrets in red boxes in homing mode)
- door opened before it was supposed to (the_room_door "a dead end? lets have a closer look")
- bullsquid tail whip wrong kill icon
- use recent version of gcc (old version auto-includes stdint.h?)
- security cards respawning?
- golden 257 not gibbing in sectore_3
- no score for mortar captured.bsp

model todo:
- fixup turret textures (chrome triangle has wrong texture, gun brace uses some of the side texture)
- merge op4 grunt models
- merge textures for monsters that split them up too much (rgrunt, most aliens)
- merge v/p/w models
- merge zombie models
- op4 grunt mp arm isnt blue

design/vision/server todo:
- make cutscenes optional or able to skip instantly for yourself
- game_text lore and author comments should be removed from any maps that are meant to be serious
- auto-add env_sound to maps that don't have it? the campaign feels more immersive with it. Almost like a different game.
- hl is meant to be relatively light on combat. no bullet sponges. No insta-respawning enemies
- not knowing what to do in a cryptic map might not be a totally bad thing, considering the alternative is usually grunt spam
- no waiting around for things to happen, like timed horde sections. "something needs to happen every 3-5 seconds" -gaben 

unreproducible bugs:
- gordonsci2 sequence never plays for button. He just stares at the button
- dead grunts/robogrunts(?) sometimes get stuck shooting invsiibly despite having no body or smth
- egon was stuck on for other player

I've noticed that new players can't do most sven maps because they're poorly designed and give no clues on what to do. So, I'm also working on making a plugin that tells you what to do and where to go in every map, complete with pathfinding that accounts for what a player can/can't reach in the moment. This will speed up map testing, detect when a map is softlocked, and lay the groundwork for better pathfinding for bots and npcs in the future. A huge project on its own. This is also high priority because whenever I do add new maps, I often see players complaining:

X: this map sucks
X: what do we do
X: pls rtv
X: rtvvvvvvvvvvvvv
- X has left the game.

In sven this is less of a problem because there is usually a veteran there who's played every map 30 times. HL on the other hand got an influx of new players who are still learning how to crouch jump.
