UE4SS Code Library

This mod is a dependency for other mods and not a stand alone mod
UE4SS s a scripting platform and a mod loader for the unreal engine. This makes it possible to load your own C++ and Lua mods. This is not possible with the normal .pak mods from Train Sim World.

This mod is a customized version of UE4SS. Unnecessary standard mods and boilerplate have been removed.
If you want to create your own c++ or lua mod, please visit the github repository of UE4SS.

Build it yourself

If you are familiar with building c++ binaries, you can also build UE4SS yourself. I have made some small changes to UE4SS, but otherwise the source code is the same as UE4SS experimental (because of the new folder structure). All my changes are open source and can be viewed in this repository: https://github.com/vanlueckn/RE-UE4SS-TSW

Would you be willing to release the source of the fork/modifications to UE4SS? There is also already another mod on here using UE4SS, which I'm sure is modified too, so already probably going to cause issues if people want to use both. Ideally the other mod (https://www.trainsimcommunity.com/mods/c3-train-sim-world/c113-announcements/i4704-automatic-train-announcements) would also release their version, and it could be worked to have one common version, but I doubt we'll get that :(

Also honestly speaking, for me loading DLL files from untrusted sources is already not ideal, so having the source would go a long way.

Thank you for your feedback. I will create a public github repo and publish instructions on how to build it. Then everyone can decide for themselves whether to download the ready-made binaries or build UE4SS themselves.

I was not aware that a mod based on UE4SS already existed. I have published UE4SS separately from my weather mod so that others can also use UE4SS as a dependency.
