Root Motion Locomotion System - Tutorial on UE5

In this tutorial, we will walk you through the process of setting up and optimizing a root motion-based locomotion system, including input keys, movement mechanics, camera management, and more. Whether you're a beginner or looking to refine your skills, this video has something for you.
📚 In this tutorial, you will learn:
- Managing camera movement, including camera lag and FOV.
- Implementing animation blueprints and setting rotation rates.
- Calculating character speed using root motion.
- Selecting and managing stand-to-move animations.
- Usage of animation graphs and blending poses.
- Usage of state machines.
⌨️ Input keys:
- Press "Space Bar" = Start Jump.
- Press "W,A,S,D" = Start to Move.
- Press "F" = Hold Weapon.

As someone who try to make this kind of locomotion system for months now, you video is giving me motivation to keep improving my gameplay mechanic. Echo locomotion is another excellent sample to learn from 🥰

[@wesleywinchester1890]

Awesome Man💯

[@Njoyy-wo9ti]

Would be great if you could create a tutorial onthis and explain everything and i mean EVERYTHING like all nodes etc (Not obv ones ofc btu yes)

[@NightfallStudios01]

Appreciate this video! Looks so good. Definitely AAA quality

[@DenzelCanvasSupport]

can you show us how to make NPCs use motion matching no video has done so for the recent sample project

[@forcepower7116]

It’s just the same as for normal npcs. Motion matching is only visual and has nothing to do with behavior

[@bumblestudio]

This looks great! But I'm a beginner in UE5 and i need a explanation on everything because i dont get some of the reasons your doing something. Howvere the movement does look rll good and it has given me a good start.

[@LocoDev]

@@bumblestudio I have a document in the description of the video, I hope it helps.
If you need anything or have questions about any node you can contact me on discord.

[@bumblestudio]

@@LocoDev thanks so much!

Can You make toturiol on climbing mountain like assassin creed do please

[@Cenk_1903]

Hello! Nice video!
I have a question,
Unreal Engine published new +500 animation new locomation sample project recently. And you mentioned about that in the some part of a video as said like "you can use(change) +500 animation pack in here"
My question is; what is the difference between your system and unreal's system.

Root Motion Locomotion System
Definition:
Root motion is a method where the movement of a character is driven directly by the animation data. The translation and rotation of the character in the game world are controlled by the root bone of the animation.
Key Features:
Animation-Driven Movement: The character's movement is dictated by the animation itself, leading to highly realistic and natural movements.
Consistency: Movement and positioning are consistent with the animations, reducing sliding or foot sliding issues.
Precision: Allows precise control over the character's trajectory and positioning.
Pros:
Realism: Provides natural and fluid character movements as they follow the exact path defined by the animation.
Consistency: Ensures that the character’s movement matches the animation perfectly.
Cons:
Complexity in Networking: Synchronizing root motion across networked games can be challenging, as discrepancies in animation playback can cause desynchronization.
Less Flexibility: Adjusting the character’s path or speed dynamically is more complex, as it is tightly coupled with the animation data.
Motion Matching System
Definition:
Motion matching is an advanced animation technique that dynamically blends and transitions between animations based on the character’s current state and desired movement. Unreal Engine's motion matching system finds the best frame from a large database of animations that matches the current and predicted future states.
Key Features:
Database of Animations: Utilizes a large set of pre-recorded animation clips to find the best match for the desired movement.
Dynamic Blending: Continuously blends animations to match the character's real-time movement and state.
State Matching: Matches animations based on parameters like speed, direction, and pose, ensuring smooth transitions.
Pros:
Flexibility: Can adapt to a wide range of movements and situations without needing specific animations for every possible state.
Smooth Transitions: Provides seamless transitions between different movements, resulting in fluid and responsive character animations.
Scalability: Can handle a large database of animations, offering extensive variety and detail in character movements.
Cons:
Complex Setup: Requires a large and well-organized database of animation clips, which can be time-consuming to create and manage.
Performance Overhead: Can be computationally intensive due to the constant matching and blending of animations.
Debugging Complexity: Debugging motion matching issues can be more complex compared to traditional animation systems.

How did you add Main States inside Weapon Poses? Ctrl+c/Ctrl+v?

[@LocoDev]

Yep

[@user-mt4ni9py7j]

What are the advantages of implementing locomotion with root motion? I wonder what the difference is.
(modify) as a separate motion -> root motion... translator changed word and I didn't check it;;;

[@LocoDev]

It depends on your project's specific needs and the poses you're tring to blend with.

[@0x8badbeef]

What does it do with joystick input? Input that is between go and stop. Ranges between 0 to 255 with a granularity of 1.

[@LocoDev]

Hello, I think it works well!

[@0x8badbeef]

@@LocoDev do you have a video showing it?

[@MrPyCCkuu1]

When calculating ActualGroundSpeed, wouldn't the character's speed then depend on the number of FPS in the game?

[@LocoDev]

I made it so that it doesn't depend on the actual FPS in the game!

[@MrPyCCkuu1]

@@LocoDev thanks for the answer
