Humanoid WalkSpeed/AssemblyLinearVelocity property not accessible on server, a day later, its accessible

I’m having trouble with network ownership as you may have noticed, and its not consistent. I am working on an core ability I will be using in my game where when a player presses space bar they will make a super leap into the air and smash into the ground.

The problem is, yesterday I tried using AssemblyLinearVelocity and WalkSpeed on the server to work on this jumping mechanism, but I had to use remote events to fire these changes on the client. I’ve gone through this problem ago a while back but its been appearing up and down like a wave.

I want to confirm why this is happening. The last time I had this issue, its because another script in my game was stopping the code I had previously made a post on.

Here is my script now(It’s a little janky since I’ve been testing with it):

local ServerStorage = game:GetService("ServerStorage")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Impact = {}
Impact.__index = Impact
function Impact.new(player)
	local self = setmetatable({},Impact)
	self.Player = player
	self.Character = self.Player.Character or self.Player.CharacterAdded:Wait()
	self.Root = self.Character:WaitForChild("HumanoidRootPart")
	self.Humanoid = self.Character.Humanoid
	self.Params = RaycastParams.new()
	self.Params.FilterDescendantsInstances = {self.Character,self.Impact}
	self.Params.FilterType = Enum.RaycastFilterType.Exclude
	self.Impact = script.GroundImpact:Clone()
	self.Impact.Parent = ServerStorage -- Parent for now
	return self
end

function Impact:Controls(signal)
	if signal == "Disable" then
		ReplicatedStorage.AdjustPlayerStats:FireClient(self.Player,"Controls",0,0,false)
	elseif signal == "Enable" then
		ReplicatedStorage.AdjustPlayerStats:FireClient(self.Player,"Controls",16,50,true)
	end
end

function Impact:Init()
	--self:Controls("Disable")
	self.Humanoid.WalkSpeed = 250
	ReplicatedStorage.AdjustPlayerStats:FireClient(self.Player,Vector3.new(0,250,0) + self.Root.CFrame.LookVector * 250,"Assembly")
	task.wait(.5)
	ReplicatedStorage.AdjustPlayerStats:FireClient(self.Player,Vector3.new(0,-250,0) + self.Root.CFrame.LookVector * 250,"Assembly")
	--self:WaitForFloor()
end

function Impact:ColorizeParts()
	for i,v in self.Impact:GetChildren() do
		local origin = v.Position
		local direction = v.CFrame.UpVector * -2
		local result = workspace:Raycast(origin,direction,self.Params)
		if result and result.Instance then
			v.Color = result.Instance.Color
			v.Material = result.Instance.Material
		end
	end
end

function Impact:JumpCast()
	local origin = self.Root.Position
	local direction = self.Root.CFrame.UpVector * -6
	local result = workspace:Raycast(origin,direction,self.Params)
	if result then
		self.Impact.Parent = workspace
		self.Impact:MoveTo(result.Position)
	end
end

function Impact:Ground()
	ReplicatedStorage.AdjustPlayerStats:FireClient(self.Player,Vector3.zero,"Assembly")
	self:JumpCast()
	self:ColorizeParts()
	self:Controls("Enable")
end

function Impact:WaitForFloor()
	local amplitude = (-self.Root.Size.Y/2 + -self.Character["Right Leg"].Size.Y)

	repeat
		print(amplitude)
		local origin = self.Root.Position
		local direction = self.Root.CFrame.UpVector * amplitude
		local result = workspace:Raycast(origin,direction,self.Params)
		if result then
			print("TouchedGround")
			self:Ground()
		end
		task.wait()
	until result
end

return Impact

My problem is very inconsistent.
This works: :white_check_mark:

game:GetService("Players").PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		character.HumanoidRootPart.AssemblyLinearVelocity = Vector3.new(0,1e4/4,0)
	end)
end)

This doesn’t::x:

function Impact:HighJump()
	self.Root.AssemblyLinearVelocity = Vector3.new(0,100,0)
	task.wait(2)
	self.Root.AssemblyLinearVelocity = Vector3.new(0,-100,0)
end

It seems like I can’t change the AssemblyLinearVelocity but can change the Humanoid properties, why is that?

The AI Assistant says the server can only modify humanoid properties but not humanoidrootpart properties. I still feel like I’ve been able to modify humanoidrootpart.AssemblyLinearVelocity on the server before though. Any answers to these doubts?
