HD2Runtime v0.40.1

A Mod for Helldivers 2
HD2Runtime akl_mod_preview_image
THIS PROJECT IS SHELVED IN FAVOUR OF FOCUSING DEVELOPMENT ON HELLFORGE


https://hf-mod.com













HD2Runtime requires BingusSharedLoader 18 or later

A modding runtime that maps many Helldivers 2 values into an easier and safer API for creating mods with much less manual reverse engineering and guesswork.

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

from personal testing, Echelon Mod Manager has been the most reliable for using HD2Runtime




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.

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.

So on compatibility if I use mods that change weapon stats that use runtime, do they conflict with each other, or do their changes apply based on which one gets priority first and don't conflict?

Like scenario 1:

Mod 1 changes liberator penetration to medium pen, but Mod 2 changes it to heavy pen, Mod 2 wins?

And if they change more than one value, does the mod that gets priority applies all value changes regardless if it has been changed or not or does it complement together with another mod that makes the same changes to one item?

Scenario 2:

Mod 1 changes liberator ergo to 100 and vert recoil to 5, Mod 2 changes liberator sway to 1 and horizontal recoil to 5. (situation 1: Mod 1 and Mod 2 don't conflict, but apply their changes to the liberator together) or (situation 2: Mod 1's changes conflicts with Mod 2 so only Mod 2's changes apply, therefore the Liberator's ergo and vertical recoil remains unchanged due to Mod 2 not changing it.)

They don't conflict, Runtime can detect if value was changed and doesn't interfere with that. So other mods (like Shodan) usually take priority. Also if some mods change different aspects of a weapon they don't even interact with each other since they only read and change their own things

Ah so it's more like Scenario 2 situation 1 then. That's nice to hear

This mod seems to cause my game to close on startup after a few seconds while having mods equipped that effect enemy behaviors.

Something weird is going on. After I updated HD2 Runtime to version 0.30 and later, I’ve tried every release after 0.30. Within just a few minutes, my game becomes nearly unplayable, or it crashes completely after several minutes of in-game play.

My specs: 13600KF + RTX 4060, 32GB RAM. With this hardware, frequent crashes like this shouldn’t happen. Everything worked perfectly fine on versions before 0.28.1. I’ve double-checked my in-game settings and NVIDIA control panel settings, nothing seems wrong.

When I used shaders based on BSL before, I only got lower FPS, and full game crashes were extremely rare. Could anyone help me troubleshoot this issue?

can you send me the hd2runtime.log

also does it crash when you run it in an isolated modpack with just bingus?

Hi, quick question before I start using mods that need HD2Runtime:

When I join a vanilla host (someone not using any mods at all) as a client, is there any known risk of causing their game to crash or become unstable? Since HD2 uses P2P, I'm worried that custom script features or desync issues might mess up a non-modded host's match or trigger crashes on their end.

Are there any specific features or scenarios known to affect a vanilla host? If so, does HD2Runtime have any safety measures built in to actively prevent these script effects from destabilizing the host's game? Thanks!

you should avoid custom stratagems and the experimental "beam conversion" and avoid putting unusual cannons / turrets on the vehicles. as they will fail to load for the non-modded player.

generally speaking, simple stat modifications of weapons is the safest and should be totally fine

Never mind, I checked my PC, my game settings, and my mods, and I'm sure the problem was that I had too many mods installed. After adjusting it, I'm now running version 30.3 and the game works perfectly.

Thanks for all the work you've put into this game. Thank you very much!!
