I remember implementing this after Laurent’s livestream. From memory, after following the CharacterMovement code path, the main issue was that braking deceleration varied over time based on the capsule’s current velocity. With my limited understanding of integrals, this made it tricky to solve for final distance (integrating with a variable that depended on its own integral). Someone with better math understanding might have seen the solution/workaround as obvious, but I had to search random math forums to find a similar problem to copy the approach of (and still didn’t really understand).

Eventually I got a solution mostly working, however it suffered from inaccuracy via framerate changes, with differences of up to 5UU depending on what framerate I tested at. That could be hacked around, but I remember being pretty frustrated capsule braking wasn’t calculated using constants.

Are you 100% positive you weren’t just missing something like floor friction from the equation?
the movement component has a specific breaking friction parameters that lengthens/lessens the movement.

Also, since we are kicking around ideas, here’s a live talk on NOT using the movement component

Data-Driven Character Movement | Live Training | Unreal Engine Livestream

this is an alternate talk with Laurent Delayen in which he essentially show the same things as the other talk (minus the warp nodes I think)

this is a talk I need to watch again as it describes the control rig stuff as well as the IK bone stuff in detail

Thank You for these links.

Are you guys using four different blendspaces for each direction (north, south, west, east) or just a 2D Blendspace?

[takapart]

Are you asking about start/stop or walking/jogging states?

Walking / Jogging

[takapart]

To be honest, I dont really care about it now.
I want to polished start nad stop animation and then focus on different states, so i’m using blendspace with two axis, one for direction from -180 to 180 and for speed from 1 to 3.
But it doesnt mean i do not want to.

Added turn in place support.

Unreal Engine 4 : Battlefront 2 Inspired Camera / Distance Matching Locomotion

Why bother?
You can achieve a perfect result of character and movement synchronization using rootmotion animations & root motion controllers, but there’s several issues with that:

First of all, with root motion the movement is baked into the animation and cannot be adjusted for gameplay reasons, can’t control the movement speed beside playing the animation faster (small margin before looking bad), if you want your character to drag more than usual because of ice on the ground you can’t, while using charactermovement component ground friction could do just that for the capsule movement.
Another issue is replication, root motion is driven by baked movement into the animation, while classic capsule based movement (CharacterMovementComponent) is driven by predictable, efficiently replicated kinematic equations.
Last but not least, artistic control, handling camera for kinematic driven capsule movement works extremely well and can be handcrafted to extreme details without unwanted movement getting in the way.

That looks amazing!
Do you have a tutorial or a repo with example setup? Would love to learn how to use this technique

[MaximeDupart]

You should really check this presentation from Laurent Delayen :

Great work!

thanks !

@ Keep it up!

[dandezign]

Would you be releasing a marketplace product or release it to the community or just to show it off?

[MaximeDupart]

Haven’t released anything to marketplace yet. Guess if the game i’m working on isn’t working out i’ll be releasing a lot of things, including this plugin.

releasing for free or you gonna sell it?

New video below:

• Added second state (Armed state)
• Added TurnInPlace 90/180 for two states
• Changed value of Braking Friction and used seperated one for testing stopping animations

** Still needs more of work **

UE4 Distance Matching WIP3.0 *Added TurnInPlace, Second State

[MaximeDupart]

nice improvements !

@ thank You!
