This is an incredibly useful node that should be a part of Unreal engine BP by default. Thank you for posting! Have you considered creating a pull request for this in Unreal engine source? If Epic approves it, it could be included in the next entire version!
Really nice stuff. Im using GAS in my project but the decoupling of this makes it very nice. I had no idea this existed either so this is super helpful
What an awesome video! Thanks so much for doing the legwork on this. It is super helpful for intermediate folks like myself who want to start customizing a bit beyond blueprints! You rock!

HI this is incredible well useful. I found i got a few error messages in how i used it so i added a bool for compleated failed and working so i could use branchs to stop trying to cancel a non active process.
Ahh I know what you mean, sorry about not going into detail on that. Before calling cancel, I always use an 'IsValid' check on the asyncAction. That will also work and is probably simpler than a bool.
Thanks for sharing and making this accessible! I tried the plugin out, and am super excited about it! I noticed though that when I did the setup you did as an example, the player has much more speed and distance if they jump while in this state vs just being on the ground. How would one go about making it consistent? I immediately felt like I was making Tracer's dash ability when testing this lol!
Hey, thank you for the support and nice feedback! I believe the distance of the controlled root movement itself should be the same on the ground and in the air since it should ignore ground friction. I believe what gives you more distance in the air is that the velocity after the movement ends is being kept, while on the ground, ground friction will kick in at that point and slow you down. On the node you can use the 'Velocity on Finish Mode' setting to get your desired result. You'd probably want to use 'Set Velocity on Finish' and just set it to 0, 0, 0 to keep the distance consistent between grounded and airborne!
Thanks for responding! I have it set to 0, 0, 0 for that setting, but I noticed that the player can go farther for slightly longer if they jump before pressing the button and even longer and farther if they do it mid-momentum.@@CobraCode
I have a behind the scenes question. Does this mean that the current frame's delta-velocity of the root bone is constantly applied and therefore linearly increase the speed? or is the previous frame's delta-velocity also removed? Because it says "constant force" but a constant force would mean that the velocity of the object keeps increasing? And what does additive do? Does that apply to other forces like gravity in the game? or does that mean that each frame's delta velocity stacks and creates a bigger force?
Hey, this is something I haven't played around with much yet, but I think you want to check the 'Is Additive' boolean on the node. You should then be able to still apply regular movement through your button inputs with the "Add Movement Input" node we usually use for walking and steering.
Hi there. I've tried building 2 diffrent projects with the plugin, but both keep showing the same error saying "Plugin 'RootMovement' failed to load because module 'RootMovement' could not be found." I'm not used to using plugins in my projects, so i dont know if this is common, but do you have any tips or ideas on how to fix it? 😅 (Both games work just fine in the editor)
Hey, thanks for letting me know about this. I'll have to look into this further and see if I can reproduce the problem. This week is really busy, so it'll probably be some time next week, sorry! This seems to be quite the common problem though and might not be specific to my plugin. Apparently a fix is to create a dummy C++ class and convert the BP only project... however a big reason for turning this into a plugin in the first place was to make it easy to use in BP only projects, so that's not the greatest solution. I found this thread with many people facing the same issue and sharing solutions, so maybe this can be helpful until I figure things out on my end: forums.unrealengine.com/t/plugin-failed-to-load-because-module-could-not-be-found/472360/8

Hey, I love how you explained everything in detail, I learned a lot from that ! But I have one question, how would you go about using it in a C++ class ? I'm defining the AsyncRootMotion class in my OnBegin event, call the activate method but nothing is happening.. Could you explain why ?

I'm trying to build a game with this plugin, but it fails almost immediately with this exception: Unable to delete Plugins\RootMovement_5.3\Intermediate\Build\Win64\x64\UnrealGame\Shipping (Unable to delete \\?\Plugins\RootMovement_5.3\Intermediate\Build\Win64\x64\UnrealGame\Shipping\RootMovement) (part of the file location taken out for security reasons) Right before that, it says its cleaning binaries
Hey, sorry about that, not quite sure what's going on there. I managed to build a project with this before. I guess it might be a difference in operating systems and the built and intermediate files don't match. Can you try going into the RootMovement_5.3 folder and deleting the Intermediate and Binaries folder? This should trigger a recompile.
Everything was working great until I tried packaging the plugin and then it just kept failing. Your videos have more than earned my patreon subscription at this point though haha so I guess I'll just do that
Thank yo so much :D Sorry but not quite sure what's going on there. When it comes to compiling C++ there can be a lot of issues with Visual Studio and if the class names don't match there's gonna be issues too. Might need some more trial and error.
I can't seem to package the plugin without getting a "Package Plugin Task failed" message. I've reinstalled Visual Studio several times over now to no avail. Is this a common issue?
Sorry to hear that. I'm not familiar with that error in particular... but yeah once visual studio gets involved there's a lot of potential for things going wrong :(
I followed the creation of the plugin and it works in engine, but when I try to build the plugin I get the error: "Monolithic headers should not be used by this module. Please change it to explicitly include the headers it needs." So I cant use it in any other project. Building the project also fails because of this. I tried to change "Engine.h" to "Engine/Engine.h" but same error...
Hmm I'm getting packaging error :( any known fix? So I've also tried doing the external package thing th-cam.com/video/e3gXGP8hBgs/w-d-xo.html from this tutorial. Still says build failed. I wasted about 4 hours on trying to figure out and no luck lmfao fml. What version of Visual Studios are you using?
Hey, I'm sorry to hear that. Sadly once visual studio gets involved there's a high potential of bugs and errors specific to your machine that are gonna be hard for me to help with. I'm using Visual Studio Community 2022 version 17.9.2
What do you mean by that? Sadly the function to use the root motion movement isn't accessible in Blueprints, so doing it in C++ is the only way for this.
No, you can create the plugin yourself if you just follow all of the steps in the video. Actually getting the packaged version of the plugin through patreon will only save you time, that's all.
