I’m currently making a system whenever you shoot the player at their limbs, the players limbs fall to the ground after. however there is a slight issue whenever I remove the joint/moter6d; it basically falls into the void, i also tried to parent the limb to the workspace, by doing that it’ll loose its texture and shading and it looks like a regular part

Was going to suggest destroying the motor, but then saw you said that lol
idk, I’m interested in that too now

I’ve found a hacky solution to this,
make a separate model with the humanoid (and clothing if character has clothes)
next parent the body part to the model
turn on can collide for part
delete the joint/motor6d
here’s the script if ur lazy i placed it under starter character scripts
task.wait(5)
local char = script.Parent
local part = char["Right Arm"];
local model = Instance.new("Model");
model.Parent = workspace;
local humanoid = Instance.new("Humanoid")
humanoid.Parent = model
local shirt_clone = char["Shirt"]:Clone()
shirt_clone.Parent = model
part.Parent = model
part.CanCollide = true;
char.Torso["Right Shoulder"]:Destroy();

I was going to say that the player’s body parts don’t have the CanCollide activated
well since its not parented to the character, i am able to enable can collide without it automatically turning can collide off

I think it would be easier just to destroy the joint/attachment and then parent it outside of the player character. For cleanup, you can track all removed limbs and destroy them after a character destroying event. Then clear the array for garbage collection, of course.

your solution kinda looks confusing, is there an easier way to do it?
Yes, but it’s the most futureproof.
In my solution, though its a bit complicated, it has 2 benefits.
-
The CustomCollision script can be used in any situation where you need to override the default Roblox collisions on a Character. Its a very stand alone script. All you need to do is SetAttribute(“CustomCollision”,), on a Characters body part, with a value of true or false to force true or false collision on that part.
Parts that do not have the “CustomCollision” attribute, will just use Roblox default collision or the last collision that was set on them (If Roblox doesn’t force it for that part) -
By just removing the joint, and keeping the part parented to the Character, this allows for body colors and clothing, and scale to still apply to the part.
Even animations, had I not renamed the parts, adding “Dead_” to the name, the arm on the ground would still be wiggling when I walk.
And yes, I went a ‘bit’ overboard, by adding a fire effect, and waiting 2 seconds before the arm falls off, but underneath the showmanship, its really very simple.
When you want a limb to fall off, you simply do this…
- SetAttribute("CustomCollision,true) – so it doesnt fall through the ground
- Rename the part, so the animations stop playing on them
- delete the Motor6D
and thats it
I got a few questions, why is there a run service event for the collision script, couldn’t you just turn on or turn off the collision with just a single line?
not only that but the remove arm script looks un necessary complicated with so much clutter, is there a way to reduce the amount of code but still work the same?
The run service is used because Roblox will constantly force set collision on body parts. The CusomCollision script really just allows us to overwrite the forced collision state on body parts.
In relation to this post, about detaching a limb, you can really just put this CustomCollision script in the starter characters and forget about it. Other than overriding the forced Roblox collision, it does nothing else.
As for the over complicated script for dropping an arm, thats my bad, ill post some super simple code in a few minutes.
function DropLeftArm(character)
--Find Parts
local leftUpperArm = character:FindFirstChild("LeftUpperArm")
local leftLowerArm = character:FindFirstChild("LeftLowerArm")
local leftHand = character:FindFirstChild("LeftHand")
--make sure we have found all of these parts before we continue
if leftUpperArm and leftLowerArm and leftHand then
--look for our motor6d
local leftShoulder = leftUpperArm:FindFirstChild("LeftShoulder")
--make sure we found the shoulder before we continue
if leftShoulder then
--let all collisions to true for the arm parts
leftUpperArm:SetAttribute("CustomCollision",true) --this causes the CustomCollision Script in the client to force this to true
leftLowerArm:SetAttribute("CustomCollision",true)
leftHand:SetAttribute("CustomCollision",true)
--now optionally we rename the parts to stop animations from playing on them
leftUpperArm.Name = leftUpperArm.Name .. "_Dead"
leftLowerArm.Name = leftLowerArm.Name .. "_Dead"
leftHand.Name = leftHand.Name .. "_Dead"
--now we destroy the motor6d so the arm can fall
leftShoulder:Destroy()
end
end
end
No, it only sets collisions on state change. It’s not possible to override collisions without this enabled:
This lil script might can help you or give you some context:
-- Define the player
local player = game:GetService("Players").LocalPlayer
-- Define the limb parts
local leftArm = player.Character.LeftArm
local rightArm = player.Character.RightArm
local leftLeg = player.Character.LeftLeg
local rightLeg = player.Character.RightLeg
-- Define the joints
local leftArmJoint = leftArm:FindFirstChildOfClass("Motor6D")
local rightArmJoint = rightArm:FindFirstChildOfClass("Motor6D")
local leftLegJoint = leftLeg:FindFirstChildOfClass("Motor6D")
local rightLegJoint = rightLeg:FindFirstChildOfClass("Motor6D")
-- Remove the joints to detach the limbs
leftArmJoint:Destroy()
rightArmJoint:Destroy()
leftLegJoint:Destroy()
rightLegJoint:Destroy()
-- Parent the limbs to the workspace
leftArm.Parent = workspace
rightArm.Parent = workspace
leftLeg.Parent = workspace
rightLeg.Parent = workspace
-- Adjust the position and rotation of the limbs
leftArm.CFrame = leftArm.CFrame * CFrame.new(0, -1, 0)
rightArm.CFrame = rightArm.CFrame * CFrame.new(0, -1, 0)
leftLeg.CFrame = leftLeg.CFrame * CFrame.new(0, -1, 0)
rightLeg.CFrame = rightLeg.CFrame * CFrame.new(0, -1, 0)
yeah but i’ve found this post that proposes the idea not using your solution you’ve made for the collision script
Thanks for linking my post, there’s a behavior in roblox that makes limbs revert their collision states every frame
You can disable this (somewhat) by changing Workspace.HumanoidOnlySetCollisionsOnStateChange
If you change the property to Enabled, then it’ll let you change collision on the parts without any spaghetti.

I am aware of the collision only being set on state change, the code I provided, was created before this change, however it still works.
Whether you set it each frame or you set it after a state change, it still works to keep the humanoid from modifying the collisions.
Interesting. The last time I tried that it didn’t work for some reason. It might’ve been because I was using RenderStepped instead of Stepped.

Hey @IceCreamPickels, might be a bit late, but you can do thise to fix the issue.
local function RemoveLimb(Hit)
local HitPlayer = Hit.Parent
local Torso = HitPlayer.Torso
local Motors = {}
--Appending all the motors inside a player
for _, Motor: Instance in ipairs(Torso:GetChildren()) do
if Motor:IsA("Motor6D") then
table.insert(Motors, Motor)
end
end
--Checks if their are still more motors left in the player to remove
if Motors then
local Humanoid = Hit.Parent:WaitForChild("Humanoid")
if Humanoid.Health < Humanoid.MaxHealth / 2 then
local Motor = Motors[math.random(1, #Motors)]
table.remove(Motors, table.find(Motors, Motor))
if Motor.Name == "Left Shoulder" then
HitPlayer["Left Arm"].CanCollide = true
Motor:Destroy()
end
if Motor.Name == "Right Hip" then
HitPlayer["Right Leg"].CanCollide = true
Motor:Destroy()
end
end
end
end
The reason why your limbs are falling into the void is because there is no collision on body parts by default.
Hoping this solution helps you and anyone who still has this problem
