VR throwing is broken

So, I have made a grabbing system for VR and the throwing is broken for no reason.


The ball just falls when I try to throw it. This is not the same problem as VR picking up object is weird because the hands are physically simulated.
The grabbing system works by using a WeldConstraint on the object to hold. Then, it destroys the weld when you want to stop holding it. The hands move with AlignPosition and AlignOrientation. The player has network ownership of the ball.

Code:

local Players = game:GetService('Players')
local ReplicatedStorage = game:GetService('ReplicatedStorage')
local UserInputService = game:GetService('UserInputService')
local RunService = game:GetService('RunService')

local Anaglyph = ReplicatedStorage.Anaglyph

local AnaglyphPhyiscs = require(Anaglyph.Physics.AnaglyphPhysics)
local AnaglyphPositionalInput = require(Anaglyph.Input.AnaglyphPositionalInput)

local Player = Players.LocalPlayer

local HeadScale = workspace.CurrentCamera.HeadScale

local Height = 5 * HeadScale
local WalkSpeed = 14 * HeadScale

local RoomWorldCenter = CFrame.new(Vector3.new(workspace.SpawnLocation.Position.X, Height, workspace.SpawnLocation.Position.Z))

Player.CharacterAdded:Connect(function(Character)
	local Humanoid = Character:WaitForChild('Humanoid')
	local HumanoidRootPart = Character:WaitForChild('HumanoidRootPart')
	local Head = Character:WaitForChild('Head')
	local LeftHand = Character:WaitForChild('LeftHand')
	local RightHand = Character:WaitForChild('RightHand')
	
	LeftHand.GrabSphere.Velocity = Vector3.new(5, 5, 5)
	RightHand.GrabSphere.Velocity = Vector3.new(5, 5, 5)
			
	Humanoid:ChangeState(Enum.HumanoidStateType.Physics)
	
	local HumanoidOffest = (Head.Position - HumanoidRootPart.Position).Magnitude
	
	local CenterRootAttachment = Instance.new('Attachment')
	CenterRootAttachment.Name = 'CenterRootAttachment'
	CenterRootAttachment.Position = Vector3.new(0, 0, 0)
	CenterRootAttachment.Parent = HumanoidRootPart
	
	local NoPhysicsRootPart = AnaglyphPhyiscs.AlignWithProxyPart(Character, Vector3.new(0, 0, 0), CenterRootAttachment)
	local NoPhysicsLeftHand = AnaglyphPhyiscs.AlignWithProxyPart(Character, Vector3.new(0, 0, 0), LeftHand.GrabSphere.Attachment, 200, 200, 200)	
	local NoPhysicsRightHand = AnaglyphPhyiscs.AlignWithProxyPart(Character, Vector3.new(0, 0, 0), RightHand.GrabSphere.Attachment, 200, 200, 200)
	
	RunService:BindToRenderStep('Tracking', Enum.RenderPriority.Input.Value, function()
		local HeadsetWorldCFrame = AnaglyphPositionalInput.TrackVRCFrameRelativeToWorldCFrame(Enum.UserCFrame.Head, RoomWorldCenter, HeadScale)
		NoPhysicsRootPart.CFrame = HeadsetWorldCFrame:ToWorldSpace(CFrame.new(Vector3.new(0, -HumanoidOffest, 0)))

		NoPhysicsRightHand.CFrame = RightHandWorldCFrame
	end)
	
	LeftHand.GrabSphere.Touched:Connect(function()
		
	end)
	
	RightHand.GrabSphere.Touched:Connect(function()
		
	end)
	
	UserInputService.InputChanged:Connect(function(Input, Processed)
		if Input.KeyCode == Enum.KeyCode.Thumbstick1 then
			local MovementDirection = (((Input.Position.X * Head.CFrame.RightVector) + (Input.Position.Y * Head.CFrame.LookVector)) * Vector3.new(1, 0, 1))
			
			local WalkVector = (MovementDirection * WalkSpeed) / 90
			
			RoomWorldCenter = RoomWorldCenter:ToWorldSpace(CFrame.new(WalkVector))

Fixed by setting Part.Velocity.

im making my own game, and ran into the same issue, how did you use part.velocity to do this?

#4

What you can do is when the grip button is released you get the Velocity of the hand that is holding the object and set the object’s Velocity to the Velocity of the hand

hey, i resolved this quite a while ago, but yeah i used that method
