Problems with visualisating

Hello! I’m trying to make a dash ability skill, but you can charge it to make the dash travel longer. So the problem I have right now is trying to show the player where he will end up accurately. I tried to search up for it on DevForum but couldnt find anything that could help me.

For dash I use BodyVelocity and for visualisating I use Beam.

Please, keep in mind that all scripts below are just summary of how it works

Dash script 
function Dash(Config: {Dir: Vector3, Power: number, Time: number})
	local Character = Player.Character
	local HumanoidRootPart = Character.HumanoidRootPart
	local RootAttachment = HumanoidRootPart.RootAttachment

	if not Config.Dir then
		Config.Dir = HumanoidRootPart.CFrame.LookVector
	end
	
	if HumanoidRootPart:FindFirstChild("KBV") then
		HumanoidRootPart.KBV:Destroy()
	end

	local KBV = Instance.new("BodyVelocity")
	KBV.Name = "KBV"
	KBV.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
	KBV.Velocity = Config.Dir * (Config.Power)
	KBV.Parent = HumanoidRootPart
	Debris:AddItem(KBV, Config.Time or 0.1)
end
Beam script 
function ShowBeam(StartLength: number, EndLength: number, Step: number)
	if not Step then Step = 1 end
	local CurrentLength = StartLength

	local Beam = Effects.AimBeam:Clone()
	local A0 = Instance.new("Attachment")
	A0.Name = "VA0"
	local A1 = Instance.new("Attachment")
	A1.Name = "VA1"
	A0.Position = Vector3.new(0, -2.9, 0)
	A0.Orientation = Vector3.new(0, 0, 90)
	A0.Parent = Player.Character.HumanoidRootPart
	A1.Position = Vector3.new(0, -2.9, -CurrentLength)
	A1.Orientation = Vector3.new(0, 0, 90)
	A1.Parent = Player.Character.HumanoidRootPart
	Beam.Parent = A0
	Beam.Attachment0 = A0
	Beam.Attachment1 = A1

	while Beam and Beam.Parent and CurrentLength < EndLength do
		local DeltaTime = RunService.Heartbeat:Wait()
		CurrentLength += Step * DeltaTime
		if CurrentLength > EndLength then CurrentLength = EndLength end
		A1.Position = Vector3.new(0, -2.9, -CurrentLength)
	end
end
Ability script 
local StartPower = 30
local PassedTime = 0
task.spawn(ShowBeam, 6, 20)

while Character:GetAttribute("Charging") == true do
	local DeltaTime = RunService.Heartbeat:Wait()
	PassedTime += DeltaTime
end
Player.Character.HumanoidRootPart.VA0:Destroy()
Player.Character.HumanoidRootPart.VA1:Destroy()
local NewPower = math.clamp(30 + PassedTime, 0, 100)
Dash({Power = NewPower, Time = 0.2})

Here’s a video of how it looks

Hello!’
Im not a scripter (I didn’t read the code) but what if you used a math function that gradually updates the player’s location so they end up at the same location as the end attachment of the beam?

Yea I solved the problem with doing something like this. Its much more reliable.
