Delay when throwing knife

[targetframed (target)]

i have a problem with my throwing knife. when my character animation has finished swinging the knife it should fly towards the target but there’s a problem. there’s a slight delay before the knife moves off to the intended target which is bugging me. i appreciate any help ty!!

client:

				throwknife_animtrack:GetMarkerReachedSignal("clone_knife"):Connect(function()
					local mouse_pos = mouse.Hit.Position
					knife_remote:FireServer("makeknife_clone", mouse_pos)
				end)

				throwknife_animtrack.Ended:Connect(function()
					knife_thrown.Value = false
					knife_remote:FireServer("makeknife_visible")
					movement_anim.AnimationId = "rbxassetid://" .. anim_table["movement"]
					movement_animTrack = animator:LoadAnimation(movement_anim)
					movement_animTrack:Play()
				end)

server:

local function knife_collision(collisionValue, transparencyValue)
	for _, part in pairs(knife:GetChildren()) do
		if part:IsA("MeshPart") then
			part.CanCollide = collisionValue
			part.Transparency = transparencyValue
		end
	end
end

knife_remote.OnServerEvent:Connect(function(p, state, mouse_pos)
	local knife_model = game.ReplicatedStorage:WaitForChild("knife_model")
	local knife_clone = knife_model:Clone()
	local vf:VectorForce = knife_clone.PrimaryPart.VectorForce
	local av:AngularVelocity = knife_clone.Handle.AngularVelocity

	if state == "makeknife_clone" then
		knife_clone.Parent = workspace
		knife_collision(false, 1)
		knife_clone:PivotTo(knife.PrimaryPart.CFrame)
		local knifeclone_pos = knife_clone.PrimaryPart.Position
		local direction = (mouse_pos - knifeclone_pos).Unit
		local throw_speed = 50
		vf.Force = Vector3.new(0, workspace.Gravity * knife_clone.PrimaryPart.AssemblyMass, 0)
		knife_clone.PrimaryPart.CFrame = CFrame.new(knife_clone.PrimaryPart.Position, mouse_pos) * CFrame.Angles(0, math.rad(180),0)
		knife_clone.PrimaryPart.AssemblyLinearVelocity = direction * throw_speed
		av.AngularVelocity = knife_clone.PrimaryPart.CFrame:VectorToWorldSpace(Vector3.new(throw_speed / 8,0,0))
		av.MaxTorque = 1000
		debrisService:AddItem(knife_clone, 5)
	elseif state == "makeknife_visible" then
		knife_collision(true, 0)
	end
end)

knife throw delay

[Giorgi311]

The delay occurs because you send the server a request to throw the knife and wait for its response.

Instead, throw the knife from client already and send this to server to make it replicate for other clients by doing a FireAllClients except for the player who requested.

Register hits from client and send this to server. Then, calculate whether such a hit is actually possible by checking the time that has passed since throwing the knife and calculating the distance it should have travelled.

There’s a bit of a delay from when the client sends a request to the server.

What you can do is make the knife still be thrown on the server but create one just for effect on the client side, so it looks seamless when the knife is thrown.

You can then just show the one that the server threw to the other clients.

(never trust the client!!)

hey man thanks a million for your help.

i did what you suggested right. so i sent the position, direction and throw speed to the server so that i could fire it to all clients and clone it on the client but it only clones for my client and not others.

i did some debugging and it only prints my name.

server:

knife_remote.OnServerEvent:Connect(function(p, state, knifeclone_pos, direction, throw_speed)
	local c = p.Character

	if state == "knife_thrown" then
		knife_collision(false, 1, c)
knife_remote:FireAllClients(p, knifeclone_pos, direction, throw_speed)
		
	elseif state == "makeknife_visible" then
		knife_collision(true, 0, c)
	end
end)

client:

knife_remote.OnClientEvent:Connect(function(player, knifeclone_pos, direction, throw_speed)
	print("Event received for player:", player.Name)  -- Debug check
	local knife_clone = game.ReplicatedStorage:WaitForChild("knife_model"):Clone()
	local vf = knife_clone.PrimaryPart:FindFirstChild("VectorForce")
	local av = knife_clone.Handle:FindFirstChild("AngularVelocity")
	
	knife_clone.Parent = workspace
	knife_clone:PivotTo(knifeclone_pos)
	
	if vf then
		vf.Force = Vector3.new(0, workspace.Gravity * knife_clone.PrimaryPart.AssemblyMass, 0)
	end
	if av then
		av.AngularVelocity = knife_clone.PrimaryPart.CFrame:VectorToWorldSpace(Vector3.new(throw_speed / 8, 0, 0))
		av.MaxTorque = 1000
	end
	
	knife_clone.PrimaryPart.AssemblyLinearVelocity = direction * throw_speed
	game:GetService("Debris"):AddItem(knife_clone, 5)
end)

oh so for the person who’s throwing the knife, i could clone that on the client but for everyone else, clone the knife on the server right?

o nvm i got it. ty guys sm for ur help. this post was a huge help too. i stored my remote event in the tool and the server script in the tool. had to put the remote in replicatedstorage and the serverscript in srvrscriptservice

FireAllClients() firing to only the player who uses it

Because each event is currently local to each client (inside of each tool) you will only get local responses to the event. You aren’t going to receive event responses from someone else’s tool in someone else’s backpack. Move the RemoteEvent somewhere both the server and all clients can access like ReplicatedStorage and ensure your server script is in ServerScriptService.
