How to make a character body part collidable?

Help and Feedback Scripting Support
#1

I am destroying Motor6D so the body part which is v would fall off as I am making a cutting limbs system. I heard about setting CanCollide to True each frame and I think that’s just what I did.

Snippet:

for _, motor6d in ipairs(character.Torso:GetChildren()) do
	if motor6d:IsA("Motor6D") then
		if motor6d.Part1 == v then
			motor6d:Destroy()

			RunSerivce.Stepped:Connect(function()
				v.CanCollide = true
			end)
		end
	end
end

What does “v” return? thrty chrctrs

A body part of a character. thrty chrctrs

Hmm, I don’t see why would you need to set it to cancollide each frame, simply, just do something like:
Character.Torso.CanCollide = true
That does it for me

Apparently, Humanoid automatically sets body part’s CanCollide to false every frame.

I don’t think you can bypass that by setting it to true every frame, it would be just a battle between both with no result and/or end.

Consider reading the article that @Seuika posted. It is the solution to what you’re looking for.

You can’t change body collision with Part.CanCollide. Check out article I posted.

I did this but it still going through the floor.

Setting PhysicsService:

local PhysicsService = game:GetService("PhysicsService")

PhysicsService:CreateCollisionGroup("Cut")
PhysicsService:CollisionGroupSetCollidable("Cut", "Cut", true)

Snippet:

for _, motor6d in ipairs(character.Torso:GetChildren()) do
	if motor6d:IsA("Motor6D") then
		if motor6d.Part1 == v then
			motor6d:Destroy()

			PhysicsService:SetPartCollisionGroup(v, "Cut")
		end
	end
end
Whole Script:

local ReplicatedStorage = game:GetService(“ReplicatedStorage”)
local PhysicsService = game:GetService(“PhysicsService”)

PhysicsService:CreateCollisionGroup(“Cut”)
PhysicsService:CollisionGroupSetCollidable(“Cut”, “Cut”, true)

local random = Random.new()

ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player, front, damage)
print(damage)

local character = player.Character

local region = Region3.new(front - Vector3.new(2, 2, 2), front + Vector3.new(2, 2, 2))

----------[ VISUALS ]---------

local part = Instance.new("Part")
part.CFrame = region.CFrame
part.Size = region.Size
part.Anchored = true
part.CanCollide = false
part.Transparency = 0.5
part.Parent = workspace

game:GetService("Debris"):AddItem(part, 0.1)

----------[ VISUALS ]---------

for _, v in ipairs(workspace:FindPartsInRegion3(region, player.Character, 1)) do
	local character = v.Parent
	local humanoid = character:FindFirstChild("Humanoid")
	
	if humanoid then
		humanoid:TakeDamage(damage)
		
		local hitSounds = character.HitSounds:GetChildren()
		local hitSound = hitSounds[math.random(#hitSounds)]
		
		hitSound.Volume = damage / 200 -- oh yea baby
		hitSound:Play()
		
		for _, motor6d in ipairs(character.Torso:GetChildren()) do
			if motor6d:IsA("Motor6D") then
				if motor6d.Part1 == v then
					motor6d:Destroy()
					
					PhysicsService:SetPartCollisionGroup(v, "Cut")
				end
			end
		end
	end
end

end)

How is it? Can you show a screen shoot of it?

you must create a part inside the bodypart that`s being cut and make it collidable

	function cpart(p)
	local rp = Instance.new("Part")
	rp.Name = "colpart"
	rp.Size = p.Size/1.4
	rp.Massless = true 				
	rp.CFrame = p.CFrame 
	rp.Transparency = 1
	rp.Parent = p
	local wc = Instance.new("WeldConstraint",rp)
	wc.Part0 = rp 
	wc.Part1 = p 
	end 

for _, motor6d in ipairs(character.Torso:GetChildren()) do
	if motor6d:IsA("Motor6D") then
		if motor6d.Part1 == v then
             cpart(motor6d.Part1)
			motor6d:Destroy()
		end
	end
end

That’s the hacky way but it gets the job done so I guess I’ll set this as the solution.

Hello, I have also found a different solution that works in a much more simpler way!

Every character that is ragdolled, should be assigned a tag with CollectionService called “Ragdoll”.
Then on the server you put all the limbs to CanCollide to true, before calculating the physics.
This can be done with RunService.Stepped event!

Here is the code, feel free to copy it!

RunService.Stepped:Connect(function()
	local ragdolls = CS:GetTagged("Ragdoll")
	for _, char in pairs(ragdolls) do
		char:FindFirstChild("Head").CanCollide = true
		char:FindFirstChild("Right Arm").CanCollide = true
		char:FindFirstChild("Left Arm").CanCollide = true
		char:FindFirstChild("Right Leg").CanCollide = true
		char:FindFirstChild("Left Leg").CanCollide = true
	end
end)

Note: Also do not forget to unassign any characters that are not ragdolled by removing their tags.
