How do I make a player dashing script?

How do I make like a dashing script where u double click w and it dashes you forward like in anime games and stuff. Do I use body velocity or is there another method?

###Since you did not attempt this/did not provide code, I will only point you in the right direction.

local UserInputService = game:GetService("UserInputService") -- service to get User Input

UserInputService.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.W then -- if they pressed w
        -- I will leave you here. It is up to you to do the dashing and all that. 
    end
end)
