Prismatic constraint pausing

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want to make a bullet slide along the ground smoothly in one direction, the way I got this to work is with a prismatic constraint.
  2. What is the issue? Include screenshots / videos if possible!
    The problem is that in this video you can see the prismatic constraint pause in the middle of its extension, which is bad.

    Also if you find it hard to see you can test it yourself on the game here
    Shoot - Roblox

Other ways I have tried to make the bullet move is by continually updating its position via a +vector3 and another method is via a floating block with an AssemblyLinearVelocity. Neither worked, The floating block did not float/was not frictionless, and the positional method was not smooth

It is worth saying this issue does not happen in Roblox studio or with the first bullet placed in the area, or strangely at all in the next rounds. I am wondering if this is a known issue with prismatic constraints and how to solve this/alternatives.

here is the code for making the bullet (ServerSide).

local function makepart(Type,parent,Name,position,anchor,size,transparency,CanColide,CanQuery,CanTouch,Attach0,Attach1)
	local part=Instance.new(Type)
	part.Parent=parent
	part.Name=Name
	if Type=="Part" then
		part.Position=position
		part.Anchored=anchor
		part.Size=size
		part.Transparency=transparency
		part.CanCollide=CanColide
		part.CanQuery=CanQuery
		part.CanTouch=CanTouch
		part.TopSurface=Enum.SurfaceType.Smooth
		part.BottomSurface=Enum.SurfaceType.Smooth
	elseif Type=="Attachment" then
		part.Position=position	
	elseif Type=="PrismaticConstraint" then
		part.Attachment0=Attach0
		part.Attachment1=Attach1
		part.ActuatorType=Enum.ActuatorType.Motor
	end

	return part
end

local function infrastructuremaker(position,BSize)
	local model=makepart("Model",game.Workspace,"Bullet")
	local bullet=makepart("Part",model,"Bullet",position+Vector3.new(0,BSize.Y/2,0),false,BSize,0,false,false,true)
	local Basepart=makepart("Part",model,"Anchor",position+Vector3.new(-4,BSize.Y/2,0),true,Vector3.new(2,2,2),1,false,false,false)
	local attachment1=makepart("Attachment",Basepart,"AnchorAttachemt",Vector3.new(1,0,0))
	local attachment2=makepart("Attachment",bullet,"BulletAttachemt",Vector3.new(-1,0,0))
	local Prism=makepart("PrismaticConstraint",bullet,"PrismaticConstraint",nil,nil,nil,nil,nil,nil,nil,attachment1,attachment2)
	Prism.MotorMaxForce=1000000
	return bullet,Prism,model
end

BulletEvent.OnServerEvent:Connect(function(player,position,speed,damage,Bsize)
	if CanPlace.Value then
		task.spawn(function()
			local bullet,Prism,model=infrastructuremaker(position,Bsize)
			Prism.Velocity=speed

			bullet.Touched:Connect(function(hit)
				if hit.Name=="Sheild" then
					model:destroy()
					local durability=hit:FindFirstChild("Durability")
					local strength=hit:FindFirstChild("Strength")
					local colordown=math.round(162/strength.Value)
					local deletecolor=Color3.fromRGB(colordown,colordown,colordown)
					durability.Value=durability.Value-damage

					if durability.Value<=0 then
						hit:destroy()
					end

					for i=1,damage do
						hit.Color=Color3.new(hit.Color.R-deletecolor.R,hit.Color.G-deletecolor.G,hit.Color.B-deletecolor.B)	
					end
				elseif hit.Name=="Goal" then
					Damager:Fire(damage)
				end
			end)
			wait(10)
			model:destroy()
		end)
	end
end)
