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

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.

[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.

try running it on a fresh profile to see if it might be other mods clashing with it
Turns out the conflict was from a mod called "M-103 FRV Turret V1.23". Also seems to be no longer on AyakaMods, so it's definitely depreciated.

Everything works fine for me on the latest version. The mod is free—why complain and give it a low rating? The author doesn't owe anyone anything. I've seen too many authors who've deleted their mods because they couldn't stand the complaints.

Oh no someone made something public and the public is having critical issues with the mod...ahh, the horrors of reviews and criticism.

Here’s what’s happening: when I launch the game, the game window disappears—just like it would during a typical crash—but the process remains visible in Task Manager. A similar crash has also occurred occasionally when finishing missions.

What should I do? This happens when using the updated HD2Runtime and HD2R Editor; however, if I enable ONLY those two along with Bingus Shared Loader, the crash doesn’t occur. What should I be looking for in the log file?

Sorry to bother you—it’s probably something trivial, but my eyes are starting to cross from staring at these logs, especially since I’m not even sure what I’m supposed to be looking for.

The log is over 400 lines long, so I don’t think I can just paste it into a comment. Could I send the log file to you via a private message?

Hello author, I've been having a great time playing with your mod! Thanks for the update.

However, I've run into the same issue as some people above: the game shows a black screen on startup and then crashes after a few seconds. After several rounds of troubleshooting, I found that a mod called "HMG-AMR-Rounds-v4-HD2-7.1_AR339564" conflicts with this mod. I suspect that those previous mods that modify weapon stats have had some bad interaction with this update. I hope this information can help you fix this issue.
