Sliding "Momentum" like in Grace

Help and Feedback Scripting Support
#1

So I’ve developed a slide system that aims to be a similar to the sliding on the game Grace, and I’ve been having some doubts on how to make something like that.

I’ve been using a BodyVelocity, which from research is pretty antiquated, but I don’t seem to see any other alternatives, since many of the others I’ve tried like LinearBodyVelocity / AngularBodyVelocity just make the player not have a gravity.

The biggest problem I have is just that the player gets stuck to walls and cannot get “unstuck” until they stop sliding, and I’d like that to not happen at any case

So if anyone has any idea on how to make something like this, it would help a lot!

(Footage and Script below)

local plr = game.Players.LocalPlayer
local char = plr.Character
local uis = game:GetService("UserInputService")

local root = char.HumanoidRootPart
local camera = workspace.CurrentCamera

local rp = RaycastParams.new()
rp.FilterType = Enum.RaycastFilterType.Exclude
rp.FilterDescendantsInstances = {char}

local dS = 16
local cS = 0
local hasStarted = false

local s = char.Humanoid:LoadAnimation(script.slidin_anim)
local can = true

char.Humanoid.StateChanged:Connect(function(ol, new)
	print("d")

	if new == Enum.HumanoidStateType.Freefall then
		if math.abs(char:WaitForChild("HumanoidRootPart").AssemblyLinearVelocity.Y) > 10 then
			can = true
		end
	else
		can = false
	end
end)

while task.wait() do
	if (uis:IsKeyDown(Enum.KeyCode.LeftControl) or uis:IsKeyDown(Enum.KeyCode.RightControl)) and char.Humanoid.FloorMaterial ~= Enum.Material.Air then	
		local i = 30
		
		local slide = Instance.new("BodyVelocity")
		slide.Velocity = char.HumanoidRootPart.CFrame.LookVector * i
		
		slide.MaxForce = Vector3.new(1,0,1) * 30000
		slide.Parent = root
		
		script.slide_sfx:Play()
		
		repeat
			script.slide_sfx.PlaybackSpeed = 1 + i/100
			s:Play()
			char.Humanoid.CameraOffset = Vector3.new(0,0,0):Lerp(Vector3.new(0, -1.5, 0), 0.25)
			slide.Velocity = char.HumanoidRootPart.CFrame.LookVector * i
					
			local deltaY = char.HumanoidRootPart.Velocity.Y;
			local deltaX = (char.HumanoidRootPart.Velocity*Vector3.new(1,0,1)).Magnitude;
			local r = workspace:Raycast(char.HumanoidRootPart.Position, -Vector3.yAxis * 25, rp)
			
			if deltaY/deltaX > 0 and can == false then
				if r then
					print(r.Instance)
					print(r.Material)
					
					if (r.Instance:IsA("Part") and r.Instance.Shape == Enum.PartType.Wedge) or (r.Instance:IsA("WedgePart")) then
						i /= 1.025
					end
				end
				
				i /= 1.005
			else
				if can == false then
					i *= 1.02
				end
			end

			task.wait()
		until not uis:IsKeyDown(Enum.KeyCode.LeftControl) or i < 0

		s:Stop()
		script.slide_sfx:Stop()
		
		char.Humanoid.WalkSpeed = 16
		game.Debris:AddItem(slide, 0.05)
		
		repeat
			char.Humanoid.CameraOffset = Vector3.new(0,0,0):Lerp(Vector3.new(0, 0, 0), 0.25)
			
			task.wait()
		until char.Humanoid.CameraOffset == Vector3.new(0,0,0)
	else
		hasStarted = false
		
		cS = 0
	end
end
