How do i account for deltaTime in this scenario?

[Nogalo]

Greetings,

I am trying to make a dash by moving the character every heartbeat, and since it runs on a variable frequency i need to account for how long deltaTime was, except i can’t figure out how to do that for a cframe, please advise

local Time = 0
local StartingCFrame = RootPart.CFrame
CC = RunService.Heartbeat:Connect(function(deltaTime)
if Time < Duration then
Time += deltaTime
StartingCFrame *= CFrame.new(0,0,-.75)
RootPart.CFrame = StartingCFrame
end
end)

I tried

StartingCFrame *= CFrame.new(0,0,-.75 + (deltaTime * 60))

but i don’t think that’s right
thank you for your time

Delta time is the time that passed from the previous frame, which in most cases it’s 1/60th of a second.
You can just do -.75*deltaTime. -0.75 is a really short distance though so I’m not sure if that’s the distance you actual want to total travel.

my goal here is to insure that no matter the time frame they cover the same distance in set amount of time, in this case .35 seconds

You’re basically trying to solve for speed, where time is a constant and distance is a constant.
Would look something like this:

local goalFrame = CFrame.new(0, 0, -5) --Dashes the player 5 studs infront
local maxDashTime = 1 --the amount of time you want the player to dash, so for this example 1 second

local elapsedTime = 0
local connection = nil
connection = RunService.Heartbeat:Connect(function(step)
    elapsedTime+=step
    rootPart.CFrame = rootPart.CFrame:Lerp(goalFrame, elapsedTime/maxDashTime)

    if elapsedTime >= maxDashTime then --When 1 second is elapsed, close connection
        connection:Disconnect()
        connection = nil
    end
end)

well ye that was my problem, i couldn’t solve for speed in a way that would account for the time the step took, some1 taught me this long ago and for the life of me i couldn’t remember. Tbh this still doesn’t give the results that i wanted but it’s by faaaar the closest i’ve got in all my countless attempts with countless methods to make a good dash on roblox. Thanks
