How to change the player's walkspeed through a script?

Help and Feedback Scripting Support
#1

I’m trying to make a script that changes the player’s WalkSpeed through a script when a round starts. (Not a localscript)

I’ve tried many different methods but none have worked.

Current method I’m trying:

local function SpinnerWalkSpeed(plr)
	local humanoid = plr.Parent:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.WalkSpeed = 0
		humanoid.JumpPower = 80
	end
end

local function DefaultWalkSpeed(plr)
	local humanoid = plr.Parent:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.WalkSpeed = 16
		humanoid.JumpPower = 50
	end
end

All help is appreciated!

Characters aren’t ancestors of their Player instances. However, Player instances do have a Character property which refers to their character model, so you’ll want to do this to define the humanoid instead:

local humanoid = plr.Character and plr.Character:FindFirstChildOfClass("Humanoid")

I get this error:
ServerScriptService.RoundScript:24: attempt to index nil with 'Character'

Did you define the player object? Also, it’s a Player Instance, right?

Also, where is the script running?

#5

It’s a normal script in serverScriptService.

What do you mean Player Instance?

#6

I don’t know how to explain it that well so let me give you an example:

game.Players.LocalPlayer -- < Local Player is the player instance
#7

I’m using a normal script. Not a local script.
How can I do this on the script?

You can use a for loop to loop through every player.

The script would look like this:

local function SpinnerWalkSpeed(plr)
	local humanoid = plr.Character:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.WalkSpeed = 0
		humanoid.JumpPower = 80
	end
end

local function DefaultWalkSpeed(plr)
	local humanoid = plr.Character:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.WalkSpeed = 16
		humanoid.JumpPower = 50
	end
end

for i, v in pairs(game.Players:GetChildren()) do
--Your function here
end

I still get the error:
`ServerScriptService.RoundScript:24: attempt to index nil with 'Character'`

#10

Have you tried adding the player character first before using the plr parameter?

I’m trying to use remote events now:

local rep = game:GetService("ReplicatedStorage")
local SpinnerWalkSpeed = rep.WalkSpeedEvents:WaitForChild("SpinnerWalkSpeer")
local DefWalkSpeed = rep.WalkSpeedEvents:WaitForChild("DefWalkSpeed")

SpinnerWalkSpeed.OnClientEvent:Connect(function()
	local player = game.Players.LocalPlayer
	local char = player.CharacterAdded:wait()
	local h = char.Humanoid

	h.WalkSpeed = 0
	h.JumpPower = 80
end)

DefWalkSpeed.OnClientEvent:Connect(function()
	local player = game.Players.LocalPlayer
	local char = player.CharacterAdded:wait()
	local h = char.Humanoid

	h.WalkSpeed = 16
	h.JumpPower = 50
end)

But this isn’t working either…
Please help

Please elaborate further, thanks! :slight_smile:

#14 
local function SpinnerWalkSpeed(plr)
	local humanoid = plr.Parent:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.WalkSpeed = 0
		humanoid.JumpPower = 80
	end
end

local function DefaultWalkSpeed(plr)
	local humanoid = plr.Parent:FindFirstChild("Humanoid")
	if humanoid then
		humanoid.WalkSpeed = 16
		humanoid.JumpPower = 50
	end
end

In the script shown above, how are you passing the arguments through to the functions?

#15

What are you passing as “plr”? The actual player, or the player’s character?

#17

Has anyone solved this post yet? Because i think I know something that might work

#19

I already got the script working. Just waiting for his response.

Oops okay! than i will delete before he is stressing out :smiley:

Sorry for the wait! Been busy.
This doesn’t seem to be working… The character’s walkSpeed is not changing. There is nothing in the output. ( it is also not printing.)

#23

I also tried yours, it also doesn’t do anything. And there’s nothing in the output
