[DISCONTINUED] Free R15 IKPF System (Inverse Kinematics Procedural Footplanting)

This is really dope. Is there a way I can make the idle stance not look like the character’s about to drop last week’s Taco Bell?

iGottic · September 14, 2020, 3:53pm

You can change the idle angle of the UpperLegs’ Hips.

Seems pretty neat! Wonder if I could try making it compatible with R6
Will be a long and time consuming task, but I guess that’s the fun in scripting

Czlopek · September 20, 2020, 10:56am

Pretty sure you gonna have to scrap 80% of entire script, beacus most of the code is positiong those three parts of each leg.

iGottic · September 20, 2020, 12:45pm

It depends which part you are using.

The procedural animation (aka “The Movement Animation”) will take much longer, because it is direct manipulation of R15/RThro joints.

However, the IK portion is very easy to apply anywhere else, as the algorithm (“FABRIK”) is universal.

dthecoolest · September 22, 2020, 2:03am

Yeah about this, any simple word explanation on how you are doing the procedural part? this is the part where I’m at after doing my own IK FABRIK system

Especially this part of the code:

		local up		=rootvelm/16
		local cycle		=up*dt*cycleSpeed
		right			=(right+cycle)%tau
		left			=(left+cycle)%tau

TL;DR:
Are you moving the target point in a circle and adjusting the circle direction based on the characters walking direction and also the floor through raycasting basically?

Any help with the units of the cycle and what is “up”

Also it’s pretty mesmerizing, tracking the “footpos” of the right leg in the gif, hope it’ll help others visualize the proccess.

Forwards:

Sideways:

I guess you could imagine a circle that’s been truncated with modulus.
Without the modulus or whatever, you would see that red bar moving in a perfect unit.
By flattening it, we reproduce that footstep appearance.

Lots of updates! I basically remade a majority of the module to benefit everybody.

OOP Programming style
Methods to disable, enable, destroy, modify, etc.
Automatic delta calculating using tick()
Automatic disabling for characters off-screen or far away
Other cleanups and minor modifications to code bits not remade

Hope you enjoy!

Wow, this is a unique module. I may use this in the future.

A quick question, how efficient is the replication?

iGottic · April 3, 2021, 8:34pm

Completely client sided, therefore completely smooth and efficient.

OminousVibes0 · April 3, 2021, 8:35pm

Oh I see, so every player calculates the animation for themselves. Even if the character is not theirs?
Sounds very impressive.

iiNanoGamezHD · April 8, 2021, 10:54pm

How Did you do that Looks really nice!

vg6m · April 30, 2021, 8:29am

how do i make the arms move? Is there Anything i can do to make the arms move?

iGottic · April 30, 2021, 2:46pm

You can animate them regularly.

iiNanoGamezHD · May 1, 2021, 12:34am

Suggestion. Will you add IK for R6

iGottic · May 1, 2021, 3:13pm

Unlikely, since resources for that already exist.

How to customize?!

iGottic · May 2, 2021, 9:32am

iGottic:

Module Documentation

-- '*' Symbol means the parameter is optional
[IKProfile] Module.New(Instance Player, Double Stride*, Double CycleSpeed*, Double MaxRenderDistance*, Double RaycastOffset*)
-- Creates an IKPF profile based on a player inputted.

[Boolean] IKProfile:IsActive() -- Checks if the profile is active
[Void] IKProfile:Enable() -- Enables the profile (done so by default)
[Void] IKProfile:Disable() -- Disables the profile
[Void] IKProfile:Destroy() -- Destroys the profile
[Void] IKProfile:Update() -- Plays the next frame of the profile

Check the documentation for basic customization.

Thanks! This will help a lot!!
