It’s not really necessary, since the point of Inverse Kinematics is to make a series of joints move in an orderly and *realistic fashion towards a goal. It’s basically like the Constraint mode/Physical dragger in studio that can move Robotic arms made of constraints.
So we don’t really need it to have any affect on R6, although it may be nice to have it as a simple “Point joint towards” instance.
Editing since I don’t just want to reply to a person; forgot to type out my thoughts since I’m late to this party.
Overall love this, I’ve so far messed around with procedural grabbing, and any sequence of movement it requires, such as crouching; as well as constraining the arms on a vehicle’s steering wheel which worked somewhat. Currently don’t have my external HDD with the files so no images or videos.
Overall; My personal Update rating is: [8/10] ████████░░
just realised the IK control couldn’t be toggled in live game yet at the moment and spent quite of a time putting IK into the experience would there be any chance that we can choose to toggle the IK beta options in live game very soon in future?
Anyone happen to know why my arms are bending inwards?
Currently I’m sitting in a seat.
local replicatedStorage = game:GetService('ReplicatedStorage')
local modules = replicatedStorage:WaitForChild('Modules')
local lib = modules:WaitForChild('Library')
local string = require(lib:WaitForChild('String'))
local module = {}
function module:AddTarget(character: Model, bodyPart: 'LeftArm' | 'RightArm', target: Attachment, includeTorso: boolean)
assert(bodyPart == 'LeftArm' or bodyPart == 'RightArm', 'Failed to add target because BodyPart ' .. tostring(bodyPart) .. ' is invalid!')
local humanoid = character:WaitForChild('Humanoid') :: Humanoid
local ikc_ThisArm = (character:FindFirstChild('IKC_' .. bodyPart) or Instance.new('IKControl')) :: IKControl
ikc_ThisArm.Name = 'IKC_' .. bodyPart
local side, bodyPart = select(1, unpack(string.split(bodyPart, '%u%l+')))
ikc_ThisArm.ChainRoot = if includeTorso then character:WaitForChild('UpperTorso') else character:WaitForChild(side .. 'Upper' .. bodyPart)
ikc_ThisArm.EndEffector = character:WaitForChild(side .. 'Hand')
ikc_ThisArm.Target = target
ikc_ThisArm.Pole = (target.Parent :: Instance):FindFirstChild(target.Name .. 'OUT')
ikc_ThisArm.Parent = character
end
return module
I’ve two attachments, one called “IK_Left” for the left arm, “IK_Right” for the right, and then I have two additional attachments who have the same name but with a suffix “OUT”, yet the arm appears to bend wrongly regardless of whether the pole is specified or not. I’ve also tried moving and rotating the out attachments to no avail.
With the new update my solution worked you can make R6 work by adding a extra limb to the end of the body part you want to use as end effector. Select the additional limb “part” that you added as end effector (dont forget to align it perfectly outward of the body part) and select the body part as chain after that it should work. And IKControls lags my game too much while play testing in the studio and I just test it with two IKControls not like sixteen (which is the max limit of my game can have cause of the server size etc) big optimization issue.
I’ve been getting massive FPS drops when I enable the IK controllers. A few days ago this didn’t happen, but I was wondering if this was a known issue before I make a detailed bug report. (I can DM the report or message it to the bug report group)
Other than that, once poles are added (or re-added I should say) this feature would be perfect!
+1 to the FPS drop issue as well also can pinpoint the issue is related to dummy humanoid contains saved IK animation keyframe and removing those animation keyframe from workspace solved the FPS drop issue
Also, would like to ask about the approximate timeframe that we can use IK control instance in live game and not only in studio?
Hi, thank you for your feedback. We’ve recently released an update that should fix the issue you were having with your own rig with motors, please check if it now works for you.
When you say “no bones in the chain”, do you mean having EndEffector same as ChainRoot or EndEffector the direct child of ChainRoot in the rig?
would there be any chance that we can choose to toggle the IK beta options in live game very soon in future?
