Vector Velocity doesn't work

Help and Feedback Scripting Support
#1

Hello developers! For my game, I made a system where you can hold and move different props. For that I used align orientation and vector velocity. But for some reason when I activate script, it doesn’t immediately start working, but rather prop moves to camera out of nowhere without aligning orientation.
Here’s the script:

local model = prop.Model
local playerInfo = LocalServerInfo.GetLocalPlayerInfo()
playerInfo.isHoldingProp=true
	
local attachment = Instance.new("Attachment",model.PrimaryPart)
attachment.CFrame=CFrame.new(0,0,0)
	
local alignOrientation = Instance.new("AlignOrientation",attachment)
alignOrientation.Attachment0=attachment
alignOrientation.Mode=Enum.OrientationAlignmentMode.OneAttachment
alignOrientation.Enabled= true
	
local linearVelocity = Instance.new("LinearVelocity",attachment)
linearVelocity.Attachment0=attachment
linearVelocity.MaxForce=MaxForce
linearVelocity.Enabled=true
	
local connection
local holdcoro
	
holdcoro = coroutine.wrap(function()
	while playerInfo.isHoldingProp do
                print("Started Holding")
		local cameracframe = camera.CFrame
		local desiredPosition = cameracframe*CFrame.new(0,0,-CurrentHoldDistance)
		local rx,ry,rz = cameracframe:ToOrientation()
		alignOrientation.CFrame=CFrame.new() * CFrame.Angles(math.rad(rx),math.rad(ry),math.rad(rz))
		--alignOrientation.CFrame=cameracframe.LookVector
		local lookVector = (desiredPosition.Position - attachment.WorldCFrame.Position).unit
		local distance = (desiredPosition.Position - attachment.WorldCFrame.Position).Magnitude
		
		local speed = (distance/0.1)
		if speed < 0.05 then speed = 0 end
		local velocity = lookVector*(distance/0.1)
                print("Current VectorVelocity Velocity: ",velocity)
		linearVelocity.VectorVelocity=velocity
		--model:SetPrimaryPartCFrame(desiredPosition)
		
		task.wait(0.05)
	end
end)
holdcoro()

Here’s a video of it:

Can I ask what ‘MaxForce’ is? If it is too low of a value, it will not have enough power to lift the object in the first place.

Oh, it’s 10000 higher in the script

#4

Try modifying MaxForce to a higher value like 100000 or 1000000 and tell me if anything changes.

Even better: inf.

No, it’s the same
here’s video

#7

Did you parent the LinearVelocity and AlignOrientation?

#8

Yeah they’re attachment’s children

#9

I’m not an expert when it comes to physics in Roblox, but try parenting it to the part rather than the direct attachment.

#10

No, it didn’t work. I have a feeling that it somehow connected to client’s performance, but I can’t say for sure

#11

Can you see the LinearVelocity and AlignOrientation instances inside the prop in the explorer in-game? I’m stumped, just trying to narrow down an answer.

#12

Yeah, they’re in workspace on client side

#13

why not use align position rather than vector velocity?

#14

Same thing. I mean it works, just like Velocity, but the problem is that it works only after some time, like it’s shown in the first video. It takes like a minute for the prop to start moving

#15

I found what was the problem. Basically, I created align instances on client and I didn’t set the said client as network owner. So basically I needed to create remote event and using it tell server to set client to network owner like this

remote.OnServerEvent:Connect(function(player,status,prop)
	if status then
		prop.PrimaryPart:SetNetworkOwner(player)
	else
		prop.PrimaryPart:SetNetworkOwner(nil)
	end
end)
