Updating cframe lags whole server [URGENT]

Help and Feedback Scripting Support
#1

Hello
Im trying to make a climbing system using cframes and doing so im changing them on the client.
To replicate it to the server i constantly update it to the server, making everything lag like crazy.
Do you know a better way to do so?

My local script:
hS is basically a variable if the player is holding the S key

	while hS do
		local ray3 = workspace:Raycast(hrp.Position + Vector3.new(0, -.6, 0), hrp.CFrame.LookVector * 8, params2)
			if not ray3 then -- onder
				stop(nil, nil, "Stop")
					immobilize()
					print("Onder")
					return
				end
					canManoeuvre(-hrp.CFrame.UpVector)
					idleAnim()
					hrp.CFrame *= CFrame.new(0, -upDownIncrements, 0)
					update() -- we look at this
					task.wait()
				end

In the update() function i constantly send out a remote event

local function update()
	remote:FireServer("Update", hrp.CFrame)
end

And in the server i do this:

if arg == "Update" then
		hrp.CFrame = CF
	end

With another player: https://gyazo.com/baf42eed9726edae3c56b95170c33a0b
Is there a better way to do this?

  1. In your local script, create a debounce variable to track the time since the last update:
local lastUpdate = tick() -- Initialize to current time

local function debounceUpdate()
    local currentTime = tick()
    if currentTime - lastUpdate >= 0.1 then -- Adjust the debounce delay as needed
        lastUpdate = currentTime
        remote:FireServer("Update", hrp.CFrame)
    end
end
  1. Modify your update() function to call the debounceUpdate() function instead of directly sending the update to the server:
local function update()
    debounceUpdate()
end
  1. On the server, handle the updates as before:
if arg == "Update" then
    hrp.CFrame = CF
end

wont this make everything less smooth?

#4

Try using Cframe interpolation

#5

what’s that? do you have an article on that or can you explain in short?

#6

Smooth movements basically in a 3D environment without any weird stutter or anything

#7

Between positions too that can help

#8

well, sounds good to me. how do implement that?
Server or client?

  1. Modify the local script:

    • Add a variable to store the previous CFrame value:

      local previousCFrame = hrp.CFrame

    • Replace the line hrp.CFrame *= CFrame.new(0, -upDownIncrements, 0) with the following code to perform CFrame interpolation:

      local targetCFrame = hrp.CFrame * CFrame.new(0, -upDownIncrements, 0)
local interpolationFactor = 0.1 -- Adjust this value for desired smoothness
hrp.CFrame = previousCFrame:Lerp(targetCFrame, interpolationFactor)
previousCFrame = hrp.CFrame

    • Remove the update() function and the line remote:FireServer("Update", hrp.CFrame).

  2. Modify the server-side code:

    • Remove the code block:
      if arg == "Update" then
  hrp.CFrame = CF
end
#10

well, doesn’t the server need to know when to update the CFrame to the Humanoidrootpart? because other players need to see the player climbing too

#11

You know what here is the ai lol

  1. Local Script:

    • Replace the line hrp.CFrame *= CFrame.new(0, -upDownIncrements, 0) with the following code:
      local targetCFrame = hrp.CFrame * CFrame.new(0, -upDownIncrements, 0)
local interpolationFactor = 0.1 -- Adjust this value for desired smoothness
hrp.CFrame = previousCFrame:Lerp(targetCFrame, interpolationFactor)
previousCFrame = hrp.CFrame

-- Send the updated CFrame to the server
remote:FireServer("UpdateCFrame", hrp.CFrame)

  2. Server Script:

    • Modify the server-side code to handle the updated CFrame:
      remote.OnServerEvent:Connect(function(player, arg, newCFrame)
  if arg == "UpdateCFrame" then
    -- Update the player's CFrame on the server
    hrp.CFrame = newCFrame

    -- Broadcast the updated CFrame to all other players
    for _, otherPlayer in ipairs(game.Players:GetPlayers()) do
      if otherPlayer ~= player then
        remote:FireClient(otherPlayer, "UpdateCFrame", player, newCFrame)
      end
    end
  end
end)

-- Add a listener for when players join the game
game.Players.PlayerAdded:Connect(function(player)
  -- Send the current player's CFrame to the newly joined player
  remote:FireClient(player, "UpdateCFrame", player, hrp.CFrame)
end)

  3. Client Script:

    • Add the following code to handle the updated CFrame from other players:
      remote.OnClientEvent:Connect(function(player, arg, newCFrame)
  if arg == "UpdateCFrame" then
    -- Update the CFrame of the specified player on the client
    local character = player.Character
    if character then
      local hrp = character:FindFirstChild("HumanoidRootPart")
      if hrp then
        hrp.CFrame = newCFrame
      end
    end
  end
end)

With these modifications, hopefully it helps you know

#12

oh sorry for asking for help, didn’t know it was so hard for you. Thank you, I will try it out tomorrow

#13

Yea no I just use the AI to go around devforum so

#14

but hopefully that helps if there’s error you might need to debugging

#15

this may or may not be a dumb question but won’t this lag too as we are still send like 200+ remote event requests?

#16

You’re right, sending a large number of remote event requests can potentially cause lag. To optimize the performance, you can implement a throttling mechanism to limit the frequency of updates being sent.

Here’s a modified version of the code that incorporates a throttling mechanism:

  1. Local Script:

    • Replace the line remote:FireServer("UpdateCFrame", hrp.CFrame) with the following code:
      local targetCFrame = hrp.CFrame * CFrame.new(0, -upDownIncrements, 0)
local interpolationFactor = 0.1 -- Adjust this value for desired smoothness
hrp.CFrame = previousCFrame:Lerp(targetCFrame, interpolationFactor)
previousCFrame = hrp.CFrame

-- Check if enough time has passed since the last update
local currentTime = tick()
if currentTime - lastUpdateTime >= updateInterval then
  -- Send the updated CFrame to the server
  remote:FireServer("UpdateCFrame", hrp.CFrame)
  lastUpdateTime = currentTime
end

  2. Server Script:

    • Add the following variables at the top of the script:

      local updateInterval = 0.1 -- Adjust this value for desired update frequency (in seconds)
local lastUpdateTimes = {} -- Stores the last update time for each player

    • Modify the server-side code to handle the updated CFrame:

      remote.OnServerEvent:Connect(function(player, arg, newCFrame)
  if arg == "UpdateCFrame" then
    -- Check if enough time has passed since the last update for this player
    local currentTime = tick()
    local lastUpdateTime = lastUpdateTimes[player]
    if not lastUpdateTime or currentTime - lastUpdateTime >= updateInterval then
      -- Update the player's CFrame on the server
      hrp.CFrame = newCFrame

      -- Broadcast the updated CFrame to all other players
      for _, otherPlayer in ipairs(game.Players:GetPlayers()) do
        if otherPlayer ~= player then
          remote:FireClient(otherPlayer, "UpdateCFrame", player, newCFrame)
        end
      end

      -- Update the last update time for this player
      lastUpdateTimes[player] = currentTime
    end
  end
end)

bro, I’m assuming you are using an Ai or some shi. I can literally tell you did not write this, if you don’t know, just say and leave I created this topic for people who may know a solution or who can bring me a step forward. This is not it

#18

he was saying he been using ai past 10 minute how is you not noticed.

your code has updating a lot very frequeast and it
s hard to see what you trting do maybe you can simply the code.

#19

yes I noticed but I thought maybe it worked idk why I didn’t tell earlier.

What I’ve said is that I’m sending too many requests to the server and that causes lag, maybe someone knew a work around to this

#20

he sort of did say he was using ai…

Personally, I don’t think it’s really a good idea to be using AI on devforum posts… the point(in my opinion) is for people who see a post on a subject they understand to #1 explain what they did wrong and #2 show them how to fix it
