How i can improve this dash system and how i fix the friction/Velocity boost with walls?

  1. What do you want to achieve?

i want to achieve a dash like this (or a near one):

Not getting stucked in the wall

  1. What is the issue?

My dashes are to buggy and “forced”, the Jujutsu shenanigans
one is very soft.
I dont know what is good for dashes (Body velocity, linear velocity, apply impulse, or tweening)

and my dash get a little boost and can get stuck when i dash to a wall

  1. What solutions have you tried so far?

i searched, but i didnt find something that help me rather than using raycasts but i dont think that is the solution for “battlegrounds type dash” (i think).

THIS IS MY CODE:

local plr = game.Players.LocalPlayer
local chr = plr.Character or plr.CharacterAdded:Wait()
local hrp : Part = chr:WaitForChild("HumanoidRootPart")
local hum : Humanoid = chr:WaitForChild("Humanoid")
local UIS = game:GetService("UserInputService")
local RS = game:GetService("RunService")
local gameSettings = UserSettings().GameSettings

local indicator = Instance.new("Highlight")
indicator.Parent = chr
indicator.FillColor = Color3.fromRGB(255, 0, 0)
indicator.DepthMode = Enum.HighlightDepthMode.Occluded
function LV()
	local lv = Instance.new("LinearVelocity")
	lv.RelativeTo = Enum.ActuatorRelativeTo.World
	lv.Attachment0 = hrp.RootAttachment
	lv.ForceLimitsEnabled = true
	lv.ForceLimitMode = Enum.ForceLimitMode.PerAxis
	lv.VelocityConstraintMode = Enum.VelocityConstraintMode.Vector
	lv.MaxAxesForce = Vector3.new(1, 0, 1) * 100000
	lv.Parent = hrp
	return lv
end

local db = false
local type = {
	frontdash = {
		time = 0.4,
		velocity = 50,
		iteration = 200,
		min = 40 * 0,
	},
	sidedash = {
		time = 0.05,
		velocity = 60,
		iteration = 150, 
		min = 40 * 0.15,
	}
}

function dash()
	local pressedkey = nil
	if db then
		return
	end
	db = true
	local lv = LV()
	print("Dashing")
	local connection : RBXScriptSignal
	hum.WalkSpeed = .1
	hum.JumpPower = 0
	indicator.FillColor = Color3.fromRGB(0, 255, 0)
	local typ = type.sidedash
	gameSettings.RotationType = Enum.RotationType.CameraRelative
	if UIS:IsKeyDown(Enum.KeyCode.W) or hum.MoveDirection == Vector3.zero then
		pressedkey = "W"
		typ = type.frontdash
		gameSettings.RotationType = Enum.RotationType.MovementRelative
	elseif UIS:IsKeyDown(Enum.KeyCode.S) then
		pressedkey = "S"
	elseif UIS:IsKeyDown(Enum.KeyCode.D) then
		pressedkey = "D"
	elseif UIS:IsKeyDown(Enum.KeyCode.A) then
		pressedkey = "A"
	end
	local tic = tick()
	local velo = typ.velocity
	connection = RS.PostSimulation:Connect(function(dt)
		if (tick() - tic) >= typ.time then
		
			velo -= typ.iteration * dt
		end

		local md = hrp.CFrame.LookVector
		if pressedkey == "S" then
			md = -hrp.CFrame.LookVector
		elseif pressedkey == "D" then
			md = hrp.CFrame.RightVector
		elseif pressedkey == "A" then
			md = -hrp.CFrame.RightVector
		end

		lv.VectorVelocity = md * velo

		if velo <= typ.min then
			lv:Destroy()
			indicator.FillColor = Color3.fromRGB(255, 0, 0)
			db = false
			print("Stop Dashing")
			connection:Disconnect()
			gameSettings.RotationType = Enum.RotationType.MovementRelative
			hum.WalkSpeed = 16
			hum.JumpPower = 40
		end
	end)
end

UIS.InputBegan:Connect(function(input, _)
	if input.KeyCode == Enum.KeyCode.Q then
		dash()
	end
end)

I’m not really experienced in dashes, but id imagine ApplyImpulse would work better than linear velocity, but again, I dunno if that’s what your example game uses or if this even works as a dash.

Usually it could not be the dash but the default humanoids and physics interfering.

You could also try a different character controller (I will promote mine hehe but there is also robloxs new one), or even replace the character collision with a sphere to minimize friction.

There are also CFrame and manual collision checking methods with the new shapecasts.
