reactivedrop_public_src's Introduction

Alien Swarm: Reactive Drop

Alien Swarm: Reactive Drop is a standalone modification for Valve's Alien Swarm game. This repository contains the source code for Alien Swarm: Reactive Drop. Using Visual Studio you will be able to build these DLL files: client.dll, missionchooser.dll, server.dll.

What is this repository for?

Having access to the source code you can:

Add new weapons, NPCs, fix bugs and generally add new features to the game and submit them as pull requests
Create mods. Both server side and client side mods. Or fully standalone mods

Note: Mods must not be used to tamper with game's leaderboards or ranked servers.

How to modify content files

The reactivedrop folder contains games content: materials, models, scripts, sounds. For now it contains the bare minimum of files to save the repository space. If you want to add new or modify the existing game content files please do it in two commits:

First commit only adds unmodified content files. You can get them from the Alien Swarm: Reactive Drop game folder
Second commit introduces your modifications to both content files and, if necessary, source code

This way we will be able to see which changes did you introduce to the content files.

How to submit changes

Changes can be submitted as pull requests.

A pull request should be as granular as possible and only change one thing at a time. If changes are related or more complex, it would be good to start a discussion on how to approach this, before making a change to ensure it can be merged.

reactivedrop_public_src's Issues

HoIAF: participating servers should automatically subscribe to all supported maps/challenges

Cannot join ranked server from the Find Ranked Servers window which have Yanaurus Map playing

It only shows the greyed out DOWNLOAD ADDON button which is strange since this map is marked as built-in.

See the screenshot

Text box may glitch inputs

Happened to me in lobby, after sent a message the text box stuck then didn't recognize inputs anymore. I had to leave the game through task manager.

Didn't know exactly what was the cause thought

Casw marine and casw player angles

GetUpVector vscript function normalizes the z vector to always be 1.0, GetAngles has x and z always 0, GetForwardVector has z always normalized to 0

Projects - TileGen

Method of compiling tileset to bsp file
Entity that moves tiles around to create playable space at runtime
MissionChooser support for generating and distributing a layout

killing a weapon doesn't remove it's ammo

for example a map has an empty vindicator laying around, if an officer takes a vindicator with him on a mission and that weapon is killed while he is holding it, picking up the empty vindicator will make it have full clips and ammo

a cfg that gets called after instant restart

newmapsettings cfg doesnt exec anymore, need a new config name which gets executed after instant restart

update official maps to take advantage of slow_heavy_door physics collision

to check:

no slow_heavy_door

bossbar bug

the first boss bar in the array of boss bars (one which has lowest column or row) breaks when the map is loaded for the first time https://imgur.com/a/mCJdL0R , next time map is loaded it seems to be fine https://imgur.com/a/snpXGSB . however on illyn forest i noticed it breaks sometimes on next map loads too, breaks also with addons disabled

Default radialmenu.txt should be changed

Not even have requesting ammo... but sealing a door.
medic, ammo, stop, go, watch out, smile and so on :

God spot on asi-jac7-timorstation

This map has a god spot in the end of the map, swarms won't attack you if stay there, making it easy to hold the last horde

objective markers are slow

they get changed from red to green after over a second of being setcomplete, also they won't update from red to green while you are looking at the objective, you have to refresh it manually by switching to a different objective and switching back. also i think theres no way to set it incomplete (back from green to red). also making them disabled removes the yellow marker from the minimap (after over a second or so) but doesnt remove the red marker from overview

weapon unlock rebalancing

https://steamcommunity.com/app/563560/discussions/0/3426689579753353949/
Might want to cut the Tesla kills achievement down from 250 to 100. Will have to make sure that this doesn't break anything for people between 100 and 249 kills.

https://steamcommunity.com/app/563560/discussions/2/3426690094698146463/
Should consider swapping around the order of some unlocks. Medic getting all their toys right at the end is annoying.

Wrong aiming angle

In the first person, vindicator's secondary attack is still fired at the wrong angle.

high resolution timer cannot be changed realtime

With the winmm implementation, the high resolution timer could be changed on the fly. During the rewrite to ntdll, this is no longer possible.

https://github.com/ReactiveDrop/reactivedrop_public_src/blob/reactivedrop_public/src/game/server/highres_timer.cpp

Expected result:

changing rd_dedicated_high_resolution_timer to be applied realtime when changed, or when the first player joins.

Actual result:

changing rd_dedicated_high_resolution_timer is locked after first player joins and cannot be altered after.

Show only English CC

I set interface language and game language to Korean.
But The game displays English CC, instead of Korean CC. Even though there's a translated CC.

It seems to occur only in the lines of the commander.

I tested this in S-Chinese (It also has translated CC), and same problem occured too.

Steam Deck Verification: Button Prompts

Buttons at the bottom of various out-of-game screens are usually bound to a specific face button. The latest Steam Deck compatibility review implies that this is not discoverable enough. We need to add bind icons to nb_button that can't be focused with a gamepad.

env_sprite_clientside

if a "clientside" sprite which was meant to be serversided is detected, it should be destroyed and a a new serverside sprite with same properties should be created. instead of only reporting about the issue to the console

implement text filtering

We can now use the text filtering API

Filters text according to the settings on the user's Store preferences page.
Can be disabled entirely with rd_text_filtering 0 (if you want to filter text for other games but not this one for whatever reason)
Filters display names on leaderboards
Filters display names on HUD
Filters chat

Only runs on client. Does not filter game content (there's simply too much of it, and determining whether something is official or from an addon as well as who made the addon at runtime would be a lot of extra computations and API calls)

Projects - Documentation

Create level design style guide
Document all lore (and origins of lore)
Create campaign creation guide
Create challenge creation guide
Look into translating documentation

Onslaught parasites can spawn half-stuck inside a wall

See the screenshot. Parasites can spawn half-stuck inside a wall and cannot move.

https://steamcommunity.com/sharedfiles/filedetails/?id=2803003415

This happens because there's some inconsistency in parasites' hull.

Parasites have HULL_TINY set in code which is Vector(-12,-12, 0), Vector(12, 12, 12).

However, it seems that for navigation and collision they use a much bigger hull.

Earlier, for ASBI WB RNG3 challenge I did some experimenting and found that hull check set to model's bounding box Vector(-28,-22, -10), Vector(16, 21, 22) allows parasites to not get stuck when spawned as wanderer or pack or prespawn.

I assume changing collision hull to Vector(-12,-12, 0), Vector(12, 12, 12) will make parasites almost impossible to kill with ranged weapons. So we need to look at fixing the size supplied to ValidSpawnPoint()

Special medal for contributors

How about it?

Steam Deck Verification: Text Legibility

The last remaining problem preventing us from being Steam Deck Verified is text legibility. A lot of our UI is simply too small to comfortably read on a 7-inch 1280x800 screen.

As the review states:

Test failed due to poor legibility of onscreen text. It is recommended that font sizes be 12 pixels or greater in height when played at 1280 x 800 for frequently referenced text. Font sizes above 9 pixels are acceptable if strong enough contrast is used between the text and background, or the text is not regularly looked at. We also highly encourage some method of font scaling so that users can enjoy your title at comfortable viewing distances over an extended playtime. The following items were observed as having poor legibility on Steam Deck: _*Acheivements, Objectives, Mission Details, Swarmopedia, Dedicated server browser.*_

A lot of our text is exactly 9 pixels tall on the Steam Deck's native resolution.

Sync Updates List_of_Reactive_Drop_Script_Functions

None of the recently submitted new functions have been updated

spectating in first person

watching back demo replays works good, mouse movement is followed. i hosted a lobby and spectated a friend play, my camera was teleported to coordinates 0 0 1. https://imgur.com/a/ehgDkDL . however if i spectate a player's bot, i get the exact same behaviour before the recent firstperson update - your camera moves together with the spectated person but still the crosshair is not being followed and you can move it yourself. when a friend spectated me, the server host, his camera teleported to the info_player_start position, the same place where the "player" entity is located, so i guess it was spectating the player and not the marine. spectating the bot for him worked like old behaviour

Redesign mission selection screen

The new mission selection screen will have missions laid out in a grid with details on the right. The Deathmatch and Bonus Missions campaigns will be removed and replaced with tabs in this new UI.

Mission overview files and campaign files can now include tag keys, of which bonus and deathmatch are used for missions and no tags are currently used for campaigns. Tags are unordered and case-insensitive.

Update workshop uploader to understand tagged mission overviews.
Clean up mission chooser frame and merge with lobby creation mission chooser.
~~Implement map-based starting mission selection for campaigns (add advanced setting to change this to a simple grid).~~ (decided against this in prototyping)
Ensure new UI works well with controller.
Ensure new UI scales well to various resolutions.
Update Steam Workshop guide.

Feedback:

Make the tabs look better.
Clicking on the starting mission name after selecting a campaign mission should go back to the campaign.
Reduce size of ReactiveDropChallenges stringtable payloads to avoid "overflow error writing stringtable baseline" crash.
Non-campaign missions have missing rich presence logic.
Non-campaign missions don't keep marine selections on retry.
Add an indicator for official campaigns/missions.
Indicate number of missions in campaign.

Legacy Addons:
Rationale: Addons that have not been updated should still go to the correct part of the mission chooser.
These tags will be hidden on the workshop, but visible in the uploader. Mappers are free to remove (or keep) the tag when publishing an update.

Add adminoverride_Bonus tag to addons that have one-mission campaigns that are not explicitly presented as campaigns ingame. adminoverride_Bonus will cause the campaign to disappear and the mission to be tagged as bonus and inherit the hidden campaign's credits filename.
Add adminoverride_Deathmatch tag to addons that have one-mission campaigns containing a deathmatch mission with a filename starting with dm_. adminoverride_Deathmatch will cause the campaign to disappear and the mission to be tagged as deathmatch and inherit the hidden campaign's credits filename.
Implement stats website handling for these tags.
Implement client handling for these tags.
Implement listen server handling for these tags.
Implement dedicated server handling for these tags.
When ready for release: Remove "Campaign" tag and add "Bonus" tag to relevant addons.

Add warning if multiple addons add the same file

[from Dubstep]

Add warning if multiple addons add the same file. Warning should include filename and both addon names. Don't show warning if files are identical or game supports merging for this filename.

Gas particles outside the screen will automatically disappear

This happens more when a teammate throws a gas grenade.

Glitch spot on rd-nh03_groundworklabs

In the end of rd-nh03_groundworklabs during the final countdown, if someone jump in this specific spot they can glitch the countdown and make the ship to not land. People are using this to get "The Choice of Progress" achievement going there, glitching the counter then returning to lab room.

Sentry gun can be used to block spawn

I don't know if this is the intended behavior, but there's a glitch that you can use a sentry gun to totally block a spawn point of the swarms

In this example the sentry is being used to block the spawn of boomers

"door bug" - it is possible to walk into the falling door trace from the "safe" side of the door

[FR] Give the option to change campaign in the lobby

The game need a way to change the current campaign to another in the lobby menu.

The current problem is that public dedicated servers are usually stuck in Jackob's Rest unless the owner change it to another, so it happens that a group finishes the campaign and leave because the players don't want to play the same campaign every time.

The change could be by a vote system or the current leader of lobby selecting which campaign he wants based on the available campaign in the server. It would also be good if we could vote another campaign in the middle of the game if the players want it.

Now if for some reason this option is already available in the game, then it should be more evident because I personally couldn't find it myself, and of course not considering console commands since it isn't available for those who aren't the host.

Inventory

From yuno on the forums:

Would it be possible to change the layout of the weapon select menu to include more weapons at a time?
I made a professional mockup of what I imagine it to look like:

The layout change of the mission select screen was one of the best changes to come to ASRD so maybe you could do the same for the weapon menu?

Null pointer on this->player

One example:

void CASW_MarineGameMovement::DecayPunchAngle( void )
{
	if ( player->m_Local.m_vecPunchAngle->LengthSqr() > 0.001 || player->m_Local.m_vecPunchAngleVel->LengthSqr() > 0.001 )  <<<<<< Unhandled exception thrown: read access violation. this->player was nullptr.
	{
		player->m_Local.m_vecPunchAngle += player->m_Local.m_vecPunchAngleVel * gpGlobals->frametime;
		float damping = 1 - (PUNCH_DAMPING * gpGlobals->frametime);
		
		if ( damping < 0 )
		{
			damping = 0;
		}
		player->m_Local.m_vecPunchAngleVel *= damping;

There are more, but in different files, they all look related.

Happens once over 2-3 days to a server, crashdumps are available.

IAF RANKS menu bug

Happened to me in main menu, after one click "Show Global" on IAF RANKS menu i'm stuck then menu didn't recognize inputs anymore. I had to leave the game through task manager.
If you have Steam Overlay enabled, it doesn't happen.

Number of retries in UI shows a number that is bigger by 1

When starting a mission for the first time the UI in TAB screen shows "RETRIES 1" when it's actually a first try.
There's an inconsistency in showing number of retries in briefing and during mission. The in-mission number is always bigger by 1.

Buzzer blur bugs out and turns into static screenshot

When buzzer damages marines it should create a tiny blur effect that lasts less than a second. It actually looks nice when it works.
However pretty often it bugs and instead of blur it just shows a static blured screenshot from some previous buzzer attack.
Sometimes it just shows a very bright screenshot which flashes you. Other times it shows a black image.

Example:

The screenshot was take on 4fun challenge where buzzers blur lasts ~20 seconds. So basically once player is hit by buzzer they see a static screenshot all this time and can't really play.

This is especially annoying on ASBI or maps where there's a lot of buzzers, like Paranoia campaign.
It's not clear how to reliably reproduce this issue.
On my current system it happens from 1-2 buzzer hits. On previous PC it was happening when Shieldbug, Boomer or Harvester were present and expensive reflective water. E.g. on Sewer Junction map.

Workaround: disable Multicore Rendering in Video Settings. Restart game. Now the issue is gone completely. However with Multicore Rendering disabled the client framerate drops significantly on ASBI challenges.

Note: It seems to affect mostly AMD CPU users. We have reports that on AMD CPUs it starts instantly while on Intel it happens rarely.
