Help anyone with BodyVelocity

Help and Feedback Scripting Support
#1

I made dash script that uses BodyVelocity. All is okay, but when player jumps and uses dash, BV Velocity becomes twice as big. How do I can fix this?

Thanks!

If the humanoid floor material is air, just divide the velocity by 2.

I tried to do this, but nothing changed

Ok well, you should be using linear velocity anyways and not bv, but let’s say you stick w bv. Could you show me how you try to change it?

i tried to use linearVelo, but the same problem

#6 
local hum:Humanoid = char:FindFirstChildOfClass("Humanoid")
local bv
local db = false
local w = false
local s = false
local a = false
local d = false
local oldVelo

hum:GetPropertyChangedSignal("FloorMaterial"):Connect(function()
	if hum.FloorMaterial == "Air" then
		if bv ~= nil then
			oldVelo = bv.Velocity
			bv.Velocity = bv.Velocity/2
		end
	else
		if bv ~= nil then
			if oldVelo ~= nil then
				bv.Velocity = oldVelo
				oldVelo = nil
			end
		end
	end
end)

Creating bv:

if not db then
				db = true
				delay(.8, function()
					db = false
				end)
				
				local velo = 0
				local velo2 = 0
				local notair = 130
				
				if w and not s then
					velo = root.CFrame.lookVector*notair
				elseif not w and s then
					velo = -root.CFrame.lookVector*notair
				end
				
				if a and not d then
					velo2 = -root.CFrame.RightVector*notair
				elseif not a and d then
					velo2 = root.CFrame.RightVector*notair
				end
				
				if velo == 0 and velo2 == 0 then
					velo = root.CFrame.LookVector*notair
				elseif velo == 0 and velo2 ~= 0 then
					velo = Vector3.new(0,0,0)
				end
				
				if velo2 == 0 then
					velo2 = Vector3.new(0,0,0)
				end
				
				bv = Instance.new("BodyVelocity", root)
				bv.MaxForce = Vector3.new(1, 0, 1)*30000
				if game.UserInputService.MouseBehavior == Enum.MouseBehavior.LockCenter then
					bv.Velocity = velo+velo2
				else
					bv.Velocity = root.CFrame.lookVector*notair
				end
				bv.P = 0
				game.Debris:AddItem(bv, 0.08)
			end

When the bv is created, check if the floor material is air. If it is, do notair/2.

nah, nothing changed

yooo, I got a solution, but maybe it is a bit hard, so:

-- variables (not all)
local bv
local old_bv
local got_changed = false
local db = false

--checking changed
hum:GetPropertyChangedSignal("FloorMaterial"):Connect(function()
	if bv ~= nil and old_bv ~= nil then
		if hum.FloorMaterial == Enum.Material.Air then
			bv.Velocity = old_bv/2
			got_changed = true
		else
			bv.Velocity = old_bv
			got_changed = false
		end
	end
end)

--creating
if not db then
	got_changed = false
	db = true
	delay(.8, function()
		db = false
	end)

	local velo = 0
	local velo2 = 0
	local notair = 130

	if w and not s then
		velo = root.CFrame.lookVector*notair
	elseif not w and s then
		velo = -root.CFrame.lookVector*notair
	end

	if a and not d then
		velo2 = -root.CFrame.RightVector*notair
	elseif not a and d then
		velo2 = root.CFrame.RightVector*notair
	end

	if velo == 0 and velo2 == 0 then
		velo = root.CFrame.LookVector*notair
	elseif velo == 0 and velo2 ~= 0 then
		velo = Vector3.new(0,0,0)
	end

	if velo2 == 0 then
		velo2 = Vector3.new(0,0,0)
	end

	bv = Instance.new("BodyVelocity", root)
	bv.MaxForce = Vector3.new(1, 0, 1)*30000

	if game.UserInputService.MouseBehavior == Enum.MouseBehavior.LockCenter then
		bv.Velocity = velo+velo2
	else
		bv.Velocity = root.CFrame.lookVector*notair
	end

	old_bv = bv.Velocity

	if got_changed == false then
		bv.Velocity /= 2
	end

	delay(0.08, function()
		bv:Destroy()
		bv = nil
		old_bv = nil
	end)
end
