        DASHDB[player]=false

end)```

everything works but when i do the actual dash, it just sends me back and forth and everywhere

(don't mind my avatar i just thought of making it look stupid)

#

i can see that lookvectors for a sec but then it disappears

fathom crown i can see that lookvectors for a sec but then it disappears

Try Using LookVector instead of CFrames. Those predetermined CFrame is based off the world origin and will always pull you toward it.

#

Mb I wasnt verified

fathom crown Nov 23, 2025, 12:02 PM

#

i just did this

#

#

HRP.Position=DashPosition

#

still getting tp'd to random positions

fathom crown i just did this

whats the full code again

i changed the code a little bit but gives same results

tacit inlet Nov 23, 2025, 12:23 PM

#

Alright so

#

At first, your problem was that you just teleported them to the dash position, without having used a body velocity or something to propel the player forward

#

Now I'd just suggest

#

lowering the maxforce a bit

#

so it doesn't teleport you, you know?

fathom crown Nov 23, 2025, 12:27 PM

#

i don't rlly tp no more it just goes in random directions

tacit inlet Nov 23, 2025, 12:27 PM

#

Alright so

#

my suggestions are

#

lowering the max force

#

to 50,50,50

#

or 100,100,100

#

since it moves in multiple directions

#

that way it can move smoothly but surely

tacit inlet Nov 23, 2025, 12:29 PM

#

fathom crown i don't rlly tp no more it just goes in random directions

I see

#

I'm pretty sure your math is a bit wrong

#

anyway, you should probably switch to using a "BodyVelocity" instead

#

I would say it's easier to work with

#

especially for systems such as this

fathom crown Nov 23, 2025, 12:36 PM

#

didnt realize this but it used lookvector for right dash

#

fixed it

#

local DASHUSED={}

local DASHDB={}

local DASHCD=3

game.ReplicatedStorage.Remotes.Dash.OnServerEvent:Connect(function(player, message, number)
    if DASHDB[player] then return end
    DASHDB[player]=true
    if DASHUSED[player]==nil then
        DASHUSED[player]={}
    end
    if not DASHUSED[player][number] and #DASHUSED[player]<2 then
        table.insert(DASHUSED[player], number, message)
    elseif #DASHUSED[player]==2 then
        task.wait(DASHCD)
        table.clear(DASHUSED[player])
    end
    local HRP=player.Character:WaitForChild("HumanoidRootPart")
    if HRP then
        local DashPosition
        local BV=Instance.new("BodyVelocity", HRP)
        BV.MaxForce=Vector3.new(100,0,100)
        if message=="FrontDash" then
            DashPosition=(HRP.CFrame.LookVector * 25)
        elseif message=="BackDash" then
            DashPosition=(HRP.CFrame.LookVector * -25)
        elseif message=="LeftDash" then
            DashPosition=(HRP.CFrame.RightVector * -25)
        elseif message=="RightDash" then
            DashPosition=(HRP.CFrame.RightVector * 25)
        end
        BV.Velocity=DashPosition
        game.Debris:AddItem(BV,0.5)
        task.wait(DASHCD)
        DASHDB[player]=false
    end
end)

#

now it just doesn't move me

fluid hearth Nov 23, 2025, 12:45 PM

#

alr

fathom crown Nov 23, 2025, 12:46 PM

#

only moved me when i changed maxforce to math.huge

#

💔

#

also its fixed now just gotta uh

#

change debris time

fluid hearth Nov 23, 2025, 12:47 PM

#

So the deal with BodyVelocity is that it can only be applied to parts that have no NetworkOwner or it is applied by the NetworkOwner themselves

fluid hearth Nov 23, 2025, 12:47 PM

#

fathom crown also its fixed now just gotta uh

wiat what how

fluid hearth Nov 23, 2025, 12:48 PM

#

ah nvm i was talking nonsene if it is a instance then it should work on the server as well

#

mb

fathom crown Nov 23, 2025, 12:49 PM

#

i have another favor, how do i make the separate dash come back

#

like lets say

#

i used front dash

#

2 seconds ago

#

and i just used side dash

#

how do i make them come back separately in like 3 seconds

#

ok wait im sparkin an idea in my head

tardy falconBOT Nov 23, 2025, 12:50 PM

#

studio ** You are now Level 13! ** studio

fluid hearth Nov 23, 2025, 12:50 PM

#

what exactly do you mean by "come back"

fluid hearth Nov 23, 2025, 12:50 PM

#

fathom crown ok wait im sparkin an idea in my head

alr

fathom crown Nov 23, 2025, 12:51 PM

#

nvm i think im on the right track but just cant thnk of it

fathom crown Nov 23, 2025, 12:51 PM

#

fluid hearth what exactly do you mean by "come back"

it just comes back

#

means you can use it again

#

cd happens

#

you can use it again

#

in tsb, you can usually do a side dash right after a front dash

#

just making it clearer

fluid hearth Nov 23, 2025, 12:53 PM

#

Ah like tsb....

#

this kinda gives me a flash back of certain fella anyways

#

Just separte the dash systems

#

so one dash system for side dashes only and one for front and back dashes

fathom crown Nov 23, 2025, 12:56 PM

#

ok i think this one does it but its both dashes 💔

#

and im pretty sure it just resets the task.wait

fluid hearth Nov 23, 2025, 12:57 PM

#

fathom crown ok i think this one does it but its both dashes 💔

so what exactly have you done here now so i can understand

fathom crown Nov 23, 2025, 12:58 PM

#

i just did this and pray it works

#

im going toremove storeddashes i think its useless now

fluid hearth Nov 23, 2025, 1:03 PM

#

so what exactly did this do now?
aren't you trying to change he DASHCD or what am i missing

#

it feels like im misunderstanding something

fathom crown Nov 23, 2025, 1:04 PM

#

ok so i got another problem woohoo i hate problems

#

local PLRS=game:GetService("Players")
local RS=game:GetService("ReplicatedStorage")
local UIS=game:GetService("UserInputService")
local Remotes=RS:WaitForChild("Remotes")
local Dash=Remotes:WaitForChild("Dash")

local player=PLRS.LocalPlayer

local char=player.Character

local hum=char:WaitForChild("Humanoid")

UIS.InputBegan:Connect(function(input, GPE)
    if UIS:IsKeyDown(Enum.KeyCode.W) or hum.MoveDirection.Magnitude==0 and UIS:IsKeyDown(Enum.KeyCode.Q) then
        Dash:FireServer("FrontDash", 1)
    elseif UIS:IsKeyDown(Enum.KeyCode.S) and UIS:IsKeyDown(Enum.KeyCode.Q) then
        Dash:FireServer("BackDash", 1)

        Dash:FireServer("RightDash", 2)
    end
end)

#

i press W or A or S or D and it just dashes

#

didnt even press Q

fluid hearth Nov 23, 2025, 1:06 PM

#

you need to do if UIS:IsKeyDown(Enum.KeyCode.W) and UIS:IsKeyDown(Enum.KeyCode.Q) or hum.MoveDirection.Magnitude==0 and UIS:IsKeyDown(Enum.KeyCode.Q) then

fathom crown Nov 23, 2025, 1:06 PM

#

ok nvm i LIED its just the W key

fluid hearth Nov 23, 2025, 1:07 PM

#

💔

fathom crown Nov 23, 2025, 1:07 PM

#

fluid hearth you need to do if UIS:IsKeyDown(Enum.KeyCode.W) and UIS:IsKeyDown(Enum.KeyCode.Q...

ohhh

#

mb LOL

fluid hearth Nov 23, 2025, 1:07 PM

#

all gud

fathom crown Nov 23, 2025, 1:07 PM

#

i saw a youtuber do that and it worked for them so idk unless i was tweaking

fluid hearth Nov 23, 2025, 1:09 PM

#

well did it fix it?

fathom crown Nov 23, 2025, 1:10 PM

#

yeah but still have a problem with dash cd

#

lets say i did forward dash a second ago and now i just did left dash

#

in seconds it would be like

#

FD:1
LD:0
FD:2
LD:1
so on

#

and then when the dashes reach 3

#

it resets

#

to make it useable

fluid hearth Nov 23, 2025, 1:12 PM

#

i see

#

but isn't the easiest way just to separate the dashes into to different scripts

#

so they don't share a cooldown or you don't have to make more if statements

fathom crown Nov 23, 2025, 1:13 PM

#

ill just do the different scripts then

fluid hearth Nov 23, 2025, 1:14 PM

#

i mean we can try to make it work in one script you decide

fathom crown Nov 23, 2025, 1:15 PM

#

ok yk what ill just try to do it in one script since most things require one script

fluid hearth Nov 23, 2025, 1:16 PM

#

alr

#

then i think its best to try to make each dash type a function and create a 2nd DASHCD which is only for Left and Right Dashes

#

with dash types i mean front/back dashes and righ/left dashes

fathom crown Nov 23, 2025, 2:08 PM

#

ok i think i found the problem

#

it was bc i did DASHUSED[player][message] instead of DASHUSED[player][number]

#

nvm
