I have not tested this mod much (< 5 minutes), so if something else breaks, please let me know.

Develop modifications for Red Dead Redemption 2 in your favorite .NET language such as C#! Get it over at http://ragepluginhook.net/Downloads.aspx
 
What is RAGE Plugin Hook
RAGE Plugin Hook, as the name suggests, hooks into RAGE engine (Rockstar Advanced Game Engine) based games and allows developers to write plugins for the games in C#, VB.NET or any other .NET language.
That was the original idea behind the name. We started working on RAGE Plugin Hook before GTA V was released, and the original internal hook was made for Max Payne 3 as it was the closest thing we had to GTA V to prepare.
But when GTA V came out, the engine had changed quite a lot, and more importantly, GTA V was 64-bit, while Max Payne 3 was 32-bit. And at the time, we decided to scrap the Max Payne 3 part, and focus on just GTA V, with the hopes that in the future, we’d be able to support multiple games as originally intended.
Well, that time has now come, and a preliminary version of RAGE Plugin Hook is now available for Red Dead Redemption 2.
We also have some stuff to announce about Max Payne 3 at some point in the future 😉
 
Using RAGE Plugin Hook for non-developers
To use RAGE Plugin Hook. Extract the contents of the downloaded .zip directly into your game folder.
Plugins are installed into the “C#Plugins” folder.
Then launch RAGEPluginHook.exe. On the first run, you can choose whether to load all plugins, specific plugins, or none.
Once the game has fully loaded with RAGE Plugin Hook, you can press F5 (by default) to open the console. Here you can type various commands, like SetTimeOfDay, SetWeather, TeleportToPosition, TeleportToWaypoint, etc. Use the LoadPlugin command to load plugins.
NOTE: If you plan on using the console or developing, we recommend running the game in borderless mode!
NOTE: There’s currently an issue where the game will crash if you attempt to load a save.
 
Developer Information
If you’re not a developer, you can stop reading now, unless you’re interested in technical and development stuff.
It’s been a lot of work making support for multiple games for RAGE Plugin Hook, and we actually started working on multi game support before Red Dead Redemption 2 was even announced for the PC.
It’s not been a “from scratch” kind of thing. We’ve had a massive API and backend that’s been so far tailored to GTA V, and it’s taken time to make this release possible, as unlike when making a piece of software like RPH from scratch for one new game, we’ve had to comment out and modify a lot of the backend code just to get it running for a game it wasn’t originally intended for.
As such, the initial release is a simple native invocation hook (script hook, if you will), but with a few extras, like the vector classes, MathHelper class, etc. and a temporary API class called TempApi which contains a bunch of properties and methods to make things a little easier, until we can get the proper API up and running. There may also be certain console commands that don’t work at all, or error out for now.
The following types are available in the preliminary API:
Rage.TempApi
Rage.Attributes.PluginAttribute
Rage.GameFiber
Rage.Debug
Rage.Model
Rage.MathHelper
Rage.WeatherTypeIndex
Rage.WeaponHash
Rage.Vector2
Rage.Vector3
Rage.Quaternion
Rage.Rotator

Hunting Wagon V1.1

Requires Script Hook RDR2

CONTROLS

Hold down the "Stow" prompt when close to the hunting wagon (around the back) when holding a pelt/animal (default key E & X/Square on controller). You can only do this on the hunting wagon that spawns at your camp. It doesn't work on other wagons.

Hold Z on keyboard or LS/L3 on pad when near the wagon or player camp fire to open the Hunting Wagon menu.

MENU FEATURES
Camp fire menu - Menu prompt shows on portable camp fire and the one in camp you can craft at.
Call for Wagon - Spawns the wagon on a nearby road at your current location.
Send to Camp - When you no longer need the wagon and want it back at your camp. Stuff stored in the wagon will be lost.

Wagon is at camp - Menu prompt shows when near the Hunting Wagon.
Replace Wagon - Change the wagon to a different type. Only wagons with doors are supported at this time.
Style - Change lanterns, set wagon style for supported wagons. Style is saved to the wagon.
Repair - Fix and set wagon to full health.
Door - Open and close wagon back door.

Settings
Long Whistle for Wagon - Hold down the whistle (default H/Dpad up) for longer than usual to spawn wagon at a nearby road (Same as Call for Wagon).
Reset All Saved Settings - Resets wagon styles & settings to default.

Settings are saved to \Documents\Rockstar Games\Red Dead Redemption 2\hunting_wagon.ini

KNOWN ISSUES

The stuff you store in the hunting wagon doesn't save yet. So when you reload game or die you will lose stuff stored in the wagon.
No throw animation.
The physics of the pelts/animals might mess with wagon and glitch out. Big birds especially.

INSTALLATION

Install the latest Script Hook RDR2 copy both dinput8.dll & ScriptHookRDR2.dll and place them into the root of your the Red Dead Redemption 2 install folder.

Install Hunting Wagon by extracting hunting_wagon.asi and placing it into the root of your Red Dead Redemption 2 install folder.

Mod created by HCL, not by me!
 
This mod simply allow you to fly. Only work with keyboard but not gamepad now. I am not a native English speaker so sorry for my language.

Requirement
ScripthookDRD2 by Alexander Blade (Not the one on Nexus): http://www.dev-c.com/rdr2/scripthookrdr2/
Community ScripthookRDR2.NET: https://www.nexusmods.com/reddeadredemption2/mods/70
All other programs required by the above two programs.

Installation
Put the "HCL_Superpower_01.cs" into the /scripts/ folder in the RDR2 installed folder (if you have successfully installed the "Community ScripthookRDR2.NET" you should have this folder, if not, you can create one.).

Control
Z: Activate/deactivate fly mod.
W: Fly forward when fly mod is activated.
Space: Fly up when fly mod is activated.
Alt: Fly down when fly mod is activated. (This is the default radar key, of course you need to either change the radar key for the game or change the key binding of this mod.)

How to change key binding:
Simply open the file with a notepad and make the change. For example, if you want to chang the activate/deactivate key to "X", just find and change all "Keys.Z" into "Keys.X". If you want to change the fly down key to "Control", just find and chang all "e.Alt" to "e.Control".

This script is as simple as it sounds, it allows you to ragdoll your character.
 
Alexander Blade's ScriptHook needed: http://www.dev-c.com/rdr2/scripthookrdr2/
 
To go into ragdoll, press and hold K. You will stay in ragdoll until you release the key.
 
If you find any issues, please let me know. I'm relatively new to scripting 🙂
