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.

custom projectiles are upcoming in the next release ive been cooking up for the past 4 days, they allow for exactly this thing, i will add a "clone projectile" option for them for you to simplify it
Thank you, For the prompt reply.

Will HD2Runtime/ModBuilder support editing the Epoch’s lower-charge explosion, fully charged explosion and overcharge self-explosion separately?

Does this newest version allow us to add attachments to weapons or is it only allowing us to change attachment stats.

just stats for now. 0.30.0 was mainly a large api expansion and several sleepless nights worth of work to get some functioning custom stratagems in here. as well as a LOT of new fields mapped and the release of an in game editor to wrap it all up nicely

I see. Is the in game editor in favour of the tool listed here or will both be developed going forward?

both will be developed going forward as the tool allows for a bit more, like custom lua and some more help templates for things such as custom stratagems and the likes

Much appreciate bro. However, lost lots of FPS from the latest version. I dunno is it just me or not. Gotta stick with previous version for now.

can you share the log. it should only do the heavy work in the first minute at most if you have hundreds of changes

Can you make a version that doesn't disable the multiplayer support for custom strategems?

So it can only be used in single-player mode? It doesn't work in public rooms, even if I'm the host?
