Knife floats when it sticks on

Help and Feedback Scripting Support

Okay, so I’ve been having more issues while I’m modifying the game but the knife floats when I throw it at a player/npc. I’m using welds and LinearVelocity so I don’t know if it’s accurate.


important part of the script

KnifeAnimation:GetMarkerReachedSignal("SpawnKnifeDagger"):Connect(function()
			Character.Humanoid.WalkSpeed = 6
			KnifeDagger = ReplicatedStorage.Assets.KnifeDagger:Clone()
			KnifeDagger.Anchored = true
			KnifeDagger.Parent = workspace
			local KnifeDaggerDebounce = false
			local UnseatheSound = script.KnifeUnsheathe:Clone()
			UnseatheSound.Parent = KnifeDagger
			UnseatheSound:Play()
			KnifeDagger.Touched:Connect(function(Hit)
				local Humanoid = Hit.Parent:FindFirstChild("Humanoid") or Hit.Parent.Parent:FindFirstChild("Humanoid")
				if Humanoid then
					if Hit.Parent.Name ~= Player.Name and Hit.Parent.Parent.Name ~= Player.Name then
						if not KnifeDaggerDebounce then
							KnifeDaggerDebounce = true
							AttackHitboxes.CreateHitbox(Character, KnifeDagger.Size, 25, true, Humanoid.Parent.HumanoidRootPart.CFrame)
							
							local Weld = Instance.new("WeldConstraint")
							Weld.Part0 = KnifeDagger
							Weld.Part1 = Hit
							Weld.Parent = KnifeDagger
							
							local BloodSound = script.BloodSound:Clone()
							BloodSound.Parent = Hit
							BloodSound:Play()
							
							local BloodParticle = script.Blood:Clone()
							BloodParticle.Parent = Humanoid.Parent.HumanoidRootPart
							BloodParticle:Emit(50)
							
							task.delay(5, function()
								KnifeDagger:Destroy()
							end)
						end
					end 
				end
			end)
			for i=1,27 do
				KnifeDagger.CFrame = Character["Right Arm"].RightGripAttachment.WorldCFrame
				task.wait()
			end
			Character.Humanoid.WalkSpeed = 16
			task.delay(3, function()
				if KnifeDagger or KnifeDagger.Parent ~= nil then
					KnifeDagger:Destroy()
				end
			end)
		end)
		
		KnifeAnimation:GetMarkerReachedSignal("ThrowKnifeDagger"):Connect(function()
			local KnifeThrowSound = script.KnifeThrow:Clone()
			KnifeThrowSound.Parent = KnifeDagger
			KnifeThrowSound:Play()
			KnifeDagger.VectorForce.Force = Vector3.new(0, KnifeDagger.Mass * workspace.Gravity, 0)
			KnifeDagger.Anchored = false
			KnifeDagger:SetNetworkOwner(Player)
			KnifeDagger.AssemblyLinearVelocity = (Character.HumanoidRootPart.CFrame.LookVector * 100)
		end)

Have you tried making the hitbox visible to see if it is making a hitbox for you vs the character?

Not yet. The part has a special mesh so I’ll remove it and see the hitbox.

So I checked the hitbox and I tested it without the mesh. But what I’m predicting is that when it gets welded, the object is actually in the air because it’s a server side object.

So as you can see, the hitbox is the same as the knife

This is me testing it.

I mean a hitbox for the player thats hit, do you only use the knife hitbox?

I only use the knife’s hitbox.

7

Maybe try setting the network owner to nil (the server) instead of the player

The problem is that the knife is being welded to where it was from the server’s perspective, which is why it’s so far off.

When you hit a player with a knife, you’ll want to send a remote event to every client that tells them to create a copy of the knife that is then placed on the target locally.

It did work, but the knife is not transitioning smoothly.

I’m still waiting for an answer…

11

When you say the knife isn’t transitioning smoothly, are you saying the knife is seemingly teleporting on to the target’s body?

12

No, I mean like it has a short delay of pause, then it resumes. (It looks like it’s teleporting because the footage is laggy)
