How to match client and server?

Help and Feedback Scripting Support
#1

I have this problem where my projectiles stop before hitting on client side

Server side:

Client side:

Code (Server script):

if not Character:FindFirstChild("Humanoid") then return end
if not Character:FindFirstChild("HumanoidRootPart") then return end
if Character.Humanoid.Health < 0 then return end
if not Character:FindFirstChild("RightHand") then return end
local RightHand = Character.RightHand
local energyball = self.energyball:Clone()
local PrimaryPart = energyball.PrimaryPart
PrimaryPart.CFrame = RightHand.CFrame
energyball.Part.CFrame = PrimaryPart.CFrame
local BodyVelocity = Instance.new("BodyVelocity")
BodyVelocity.MaxForce = Vector3.new(1, 1, 1) * 350
BodyVelocity.Velocity = (PrimaryPart.Position - position).unit * -50
BodyVelocity.Parent = PrimaryPart
local touched = {}
PrimaryPart.Touched:Connect(function(toucher)
	local Parent = toucher.Parent
	if Parent == nil then return end
	if touched[Parent.Name] then return end
	if Parent:IsA("Workspace") then
		PrimaryPart.Anchored = true
	elseif Parent:FindFirstChild("Humanoid") and Parent ~= Character then
		PrimaryPart.Anchored = true
		touched[Parent.Name] = true
		Parent.Humanoid:TakeDamage(self.damage)
	end
end)

What can I do to fix this issue?

Where are you setting energyball’s parent to the workspace or something other than nil, after cloning it?
