Making your game moddable.

How did you do that? It’s awesome! Do I need something else than the guides I posted before?

Hey man, what do you need help with specifically?

For loading the images from disk, there is this code. (39) 's Extra Blueprint Nodes for You as a Plugin, No C++ Required! - Blueprint - Epic Developer Community Forums

The reading of text file is also quite easy to do, lots of info on it on the answer hub and forums. If you want me to share my specific code, well, just let me know.

The reading of midi file is done by the LoadFile blueprint node of a MIDI component which is already included in the Midi UE4 Plugin by Scott.

The workshop is much more complicated, so that would take longer to explain, heh.

I’m interested in the workshop but I don’t want you to invest time explaining how to do it, I just need some directions exactly as you did with the other stuff which I really appreciate, thanks.

I found this for the workshop:

A new, community-hosted Unreal Engine Wiki

UE4 Game moddable via Workshop

Howdy folks, apologies for the longest of all waits on updates here… We’ve been working with partners and on our own games (Robo Recall, specifically) in order to take the right approach to building out a reusable framework for making UE4 games moddable, and I wanted to wait until we had more to share to follow up. I think we made some great progress for Robo Recall, and a lot of that code should be heading your way in future releases (thinking 4.17 right now).

At last, great news regarding modding!

Does the new Runtime Asset Management framework have anything to do with the modding env?

Well I just finished reading the documentation for it, and I would say, yes it does. Especially the part about dynamically loading assets at runtime. This seems like a great push in the right direction.

The links masterneme posted are very helpful. However, to get started with Steamworks and getting the hang of Steam Callbacks, I also recommend the tutorial I made. As a lot of the stuff you learn there are similar to how the workshop does it.

Looks like it might help. I didn’t use it for my game, because I got lucky that all the files I need to mod my game are in a very basic format.

Hello.

I just wanted to check the ease of modding support for UE4 and found this thread.
So from what I can gather right now modding support for UE4 games are messy at best, and there might or might not be progress in this aspect with 4.17 ?

Did I get it right ?

Thanks.

Yep I think that’s correct. I really hope we get some (easy) modding capabilities with 4.17, I’m making a sprite based FPS (like Doom or DN3D) and I want people to be able to mod it like crazy.

As long as you have to force users to create github account, merge with epic account, find a mail that often goes to spam to confirm the link, download git repo, paste into folder with your game content that they downloaded through steam (and they wonder why can’t they have those few dlls and exes there as well), force them to re-download that again every time you update your game - modding is extremely excruciating experience.

Not to mention that you have to host and upload all the binaries with each next update and patch. Yeah, Git supports devs pretty nicely and you can automate that, but that’s another thing to do, along with everything you have to do on steam to upload new files to depot, create DRMs and so on. Gets old real quick.

We’ve shipped two titles with modding using UE4, and the number of mods isn’t high. We’ve created tutorials, explained in detail what users have to do and yet our support mailbox was spammed, as were steam forums. Many questions were asked as to why is it the way it is. Once people get into modding and find it fun, they’ll continue, but the first setup is FAR too cumbersome for many to overcome.

We’ve tried. Really. We wrote our own custom app that deals with the entire git by itself (stores passwords if the user allows, so just double click on exe to refresh binaries from latest git upload). This didn’t help at all. The worst step is the first one, why make it the hardest? People bailed on the start setup in the vast majority of cases. Tutorials with screens didn’t help.

Will that ever change? We’re close to releasing a third title, years pass on and this nonsense is still kept. This topic alone is over 2 years. No response to e-mails asking that question either. We’d like it to have mods, but after previous experience - I just see no hope. Only selected few, who really want to do it really hard, will ever get to try. Typical user is not a developer who deals with this kind of stuff every day.

I’m pretty sure you know all that. As I’m pretty sure it’s gonna stay like this for other reasons. Still, instead of another carrot in the form of “4.17 is gonna be cool” that I’ve heard several times about modding, please try hitting the wall I’m describing instead. We can fix technical issues. We’ve done it (probably not as nice as actual engine devs can, but still). We cannot move past legal issues as easily.

The above is why I quit learning UE… modding and dedicated servers and networking. A lot of mystery that is never ever made clear by the UE team. I had hoped after many revisions something would have changed, but it appears not. Just want to be able for people to run their own dedicated servers, and be able to make maps to add to a game, maybe mod skins and such… should be pretty easy, engines from decades ago could handle it.

Howdy folks, apologies for the longest of all waits on updates here…

Greetings.
Has there been any progress on this at all? Im being swamped with requests to support user created levels in our game, and I can’t find any realistic way to accomplish this.
Just being able to allow players to upload custom levels to workshop and then play those.
Is there no approach to do this?

Feels like this topic is getting a bit too old.

+1 on this. Is there any new development ? I am not up to date

I am specifically interested in some type of example C++ project that allows 3rd party map creation, using the project’s custom actors/components to be placed into the map, without giving up the whole source code (an anti-cheat and copyright mess, especially with marketplace assets).

And then, allowing the client to download map files during the level load phase (i.e. FPS server changing maps, and client doesn’t have the one in the rotation).

Theoretically this should all be possible with the objects I want to expose in a separate plugin, and only giving out header files and/or debug DLLs?

[AP_Studios]

I would love an answer on this one as well.
My issues will be slightly different as i am packing for pc and xbox with cross platform servers so i am not sure i can use mods that translate over … i dont know yet. guess i will find out right?! I mean assuming there is an answer on how to make them moddable.

@John_Alcatraz

I’m not sure about this modding stuff… It might be feasible for a “big” team of developers like ARK has (I call big everything > 5), but for someone who is creating a game alone or in a very small team I don’t think this is the type of modding I want to see officially supported by Epic. Small teams might only use blueprints etc, and I don’t think it will be ever possible to create a customized version of the UE4 editor just with blueprints. And then the second important thing is, I definitely don’t want the players of my game to need to know what UE4 is and how to use the UE4 editor. That’s really low level modding, while I would like to see possibilities for high level modding. This means having easy access to an ingame map editor and the ability to distribute these maps easy to other users (copy one file). I don’t know what you think, but if I play a game I don’t want to use the same editor the developers of the game use just to create a custom map. Learning how to create a custom map should not take longer than 10 minutes for the player. So clicking on a “map editor” button in the game, seeing 5 buttons for modifying the landscape, then being able to place some trees, create rivers etc (and all in “realtime” while the “game” runs) and then hit a save button, leave the map editor, and hit play and start playing the game in the custom map. That’s the type of modding most players want to do. And thats what UE4 should support.

Creating custom versions of the UE4 editor is good for big teams who have the resources to create heavy c++ customization to the editor and for being used by players who basically are themselves game developers and want to heavily customize the game. But that’s not 95% of the players who bought the game.

What you’re describing isn’t really what this thread’s about. Having an ingame user-friendly level editor with workshop distribution and stuff is super awesome but it’s not modding. For my game, I want modding of the sort that FPSes have traditionally had - fully-fledged custom maps, etc, like you get with, I dunno, CS. Or UT.

This should be a STANDARD feature of ANY game engine. Otherwise you are not really ‘modding’. Custom maps. That has what has kept many other games alive. Yet I have asked about the same thing in the past and hear nothing but crickets. Guess VR and a hundred other things are far more important to the UE4 developers.

So at this point it seems fairly obvious that epic is not going to help us with modding at all. Maybe we should start figuring out what’s necessary to achieve it ourselves instead of asking.

I am down.

Sigh, love everything else about this engine to abandon it and this simply does need to be done. let’s get a Discord going or something then.

I’m adept at C++/UE4 and could probably hack this together without outside help, but it’s best we all discuss an architecture design and split up some of the work instead of going down different roads to the same place. Best we build some empty reference/skeleton project (with a fork for potential engine modifications we can pull request to Epic master) that does this.
