ABOUT PUBLIC MATCHMAKING
its enabled again. i apologies for any troubles the initial released had caused.

here be dragons

if you encounter crashes with this in public lobbies its highly likely to be some of the experimented features that REQUIRE everyone in the lobby to have runtime installed to work correctly and safely

GameGuard:
some people have reported the recent 0.30.0 releases of hd2r has caused gameguard to refuse to boot. this is likely due to the mouse scroll wheel hook and can be disabled in your mod loader

Making a Mod with HD2Runtime

HD2Runtime is installed once and shared by mods that use it.

Creating a mod


Recommended Tool:
https://github.com/SkyeShade/HD2Runtime-ModBuilder/releases

1790642443139.png

Runtime Modbuilder is a tool i made specifically to lower the barrier of entry to modding this game.

Warning:
Some features are still experimental, and a few values may not map perfectly yet.


Manual Option:


1. Download and extract HD2Runtime-ModTemplate-<version>.zip from the github release page
2. Open the extracted folder in Rider or another code editor
3. Edit hd2runtime.json
- Change the mod name
- Change the resource ID to something unique, for example:
mods/yourname/my_mod
- Set the required HD2Runtime version for the features you use
4. Edit src/addon.lua
5. Run build.cmd
6. Import the ZIP created in the build folder into Arsenal or your mod manager
7. Enable Bingus Shared Loader, HD2Runtime, and your mod, then deploy and restart the game

Very Basic example


1790594165038.png

expect is the vanilla value Runtime expects before writing. Copy it from the SDK capability metadata; don’t guess it.


This changes the Liberator Concussive fire rate from its expected vanilla value of 400 RPM to 1100 RPM.

How do I know what values I can edit?


Download the HD2Runtime SDK from the github release and look inside its capability files.

Useful files include:

PlayerWeaponAuthoringCapabilities.json -> primary and secondary weapons
SupportWeaponAuthoringCapabilities.json ->support weapons
StratagemAuthoringCapabilities.json -> stratagems and deployed entities
VehicleAuthoringCapabilities.json -> vehicles
BackpackAuthoringCapabilities.json -> backpacks
MagazineAttachmentCapabilities.json -> magazine attachments

These files tell you:

- supported object names
- editable fields
- vanilla/default values
- whether a field is writable
- whether the edit affects shared data
- whether special safety acknowledgement flags are required

The expect value should normally come from the published baseline in these files. Do not guess it.

HD2Runtime checks the expected value before writing. If the game updated, another mod changed the value, or the target no longer matches what Runtime expects, the write is rejected instead of blindly modifying memory.

Useful operations


hd2.patch(...) -> applies one guarded change.

hd2.ensure(...) -> keeps a change applied if the game later resets it.

hd2.transaction(...) -> changes several fields on the same object together.

hd2.plan(...) -> coordinates changes across multiple objects.

Logs


If your mod does not work, check:

%LOCALAPPDATA%\CowboyBingus\Helldivers2\Logs\

Useful files:

BingusSharedLoader.log
HD2Runtime.log

APPLIED means Runtime successfully changed the value.

ALREADY_DESIRED means the value was already what your mod requested.

Full developer guide


See the HD2Runtime GitHub documentation for target navigation, safety flags, vehicles, backpacks, magazine attachments, plans, transactions and troubleshooting.

Found a bug?
Bugs are inevitable in a project as large as HD2Runtime, especially while it is still in early development.

If you find a bug or incompatibility, please reach out to me or submit an issue report on GitHub so I can investigate it and, if possible, implement a fix.



Missing feature?

If you think HD2Runtime is missing a feature or you have an idea for a new addition, feel free to reach out to me here. Please avoid opening GitHub issues for feature requests unless the request is specifically related to an existing issue.



[Disclaimers]

HD2Runtime does not support public matchmaking.

HD2Runtime is intended for private, friends only, invite only, and other controlled modded sessions where all participants have chosen to use mods.

Using HD2Runtime in public lobbies can and will lead to crashes depending on what mods are used alongside it. i cannot fix this but i will do my best

LLMs were used during the development of this mod.

Why is the mod isn't working? I installed V 0.30.0, and it can't be used in public matching, so I uninstalled it and downloaded V 0.28.1, reinstalled it. Then all my mods that depending on HD2Runtime can't be working at all. Is there some hidden feature that changed my PC settings?
i published a 0.30.1 patch to fix that

To be fair, a lot of that feedback would likely get lost in the comments if it was just that. plus people should know what they're getting into and theyre much more likely to read a review about it rather than scrolling through pages and pages of comments.

I'de only say it deserves the reviews in regards to the locking thing if the author replied to comments complaining about it saying they won't change it. Mod authors (speaking from personal experience) read every comment for signs of bugs or dissatisfied users so getting buried isn't an issue. I'm much, much happier with people reporting issues with any of my mods via comments or DM than reviews that may end up never getting adjusted after new updates

I checked v0.30.1, and reload-speed editing controls are still missing for:

- Primary weapons: 38 of 55
- Secondary weapons: 23 of 25
- Support weapons: 19 of 35

Could you review these and expose reload-speed controls wherever applicable? This would be useful for balance mods, especially on weapons where reload time is a major limitation.

queuing them up for the upcoming 0.30.2 hotfix

Would it be possible to let us put a status effect on the purifiers charged shot explosion? I want to mimic the incendiary gas upgrade the scorcher had in the first game.

What I am lowkey annoyed by is that people cry about people using mods in public lobbies. Showing a clear lack of self control from mod users. But when those that can actually help that issue work towards fixing it. (I.e. putting a barrier between modded and vanilla lobbies.) People cry about it. Says a lot about those people, doesn't it?

Awesome! That is one of the last major features I’ve been missing. That and allowing multiple status effects per round/explosion, ideally with the ability to edit the 71 effects themselves (acid rain effect defaults to 1s duration as an example, I’d like to extend that). This is an absolutely amazing program and I thank you for what I know has been a LOT of effort.
