I know how to make a ray go in a certain direction but I want a set length on that ray how do I do this?
This is what I mean by drawing.
This ray I made that goes 5 studs in front of the humanoidRootPart
This is all I can think of
This is what I want to achieve

local length = 5
local newDirection = direction.Unit * length

Correct me if I am wrong but I think yo achieve this you could use the LookVector and multiply it by the amount you desire.
local length = 5 -- Length in studs
local Direction = CFrame.LookAt(HMR position, target position) -- create a CFrame at the current HMR position and make the cframe face the target position
local ray = workspace:RayCast(HMR position, Direction.LookVector * length) -- get the way the direction CFrame is facing and multiplie it by length of ray
correct me if im wrong but this should work
this will create a ray to the way the HMR is facing but you can change it to something like this:
local length = 5
local Direction = Vector3.new(0,1,0)
local ray = workspace:RayCast(HMR position, Direction * length)
this will cast a ray up 5 studs far
HMR = Humanoid Root Part
but for your case you can change the target position of example 1 to the HMR of the player you wanna target
Okay, thanks for the help i’ll try these out
No using the lookvector of the humanoidRootPart will only make a ray in front, i want a ray in all directions
Heres my code
local RayStart = HumRoot.Position
local RayEnd = ) -- how do i make this go to the target direction but only 5 studs?
local RayParams = RaycastParams.new()
RayParams.FilterDescendantsInstances = Character:GetDescendants()
RayParams.FilterType = Enum.RaycastFilterType.Blacklist
local RayResult = workspace:Raycast(RayStart,RayEnd,RayParams)

just use the code i wrote you it should work exactly as you wanted just put in the intented params

It gives this error
local length = 5 -- Length in studs
local Direction = CFrame.LookAt(HumRoot.Position, Target.Position) -- create a CFrame at the current HMR position and make the cframe face the target position
local ray = workspace:RayCast(HumRoot.Position, Direction.LookVector * length, RayParams)
Maybe this will help
-- Objects
local rootPart1 = nil -- Set this to the first root part
local rootPart2 = nil -- Set this to the second root part
-- Functions
local function CastRay()
local raycast_params = RaycastParams.new()
-- Set whatever parameters for the raycast parameters
local rootPart1Position = rootPart1.Position -- A reference so we don't call it multiple times (optimized)
local Length = 5 -- Studs
local Direction = (rootPart2.Position - rootPart1Position).Unit * Length -- Raycast coming from rootPart1
workspace:Raycast(rootPart1Position, Direction, raycast_params)
end
Disclaimer: I probably made a typo or two, didn’t write this code in studio T_T

I fixed it by doing this
local RayStart = HumRoot.Position
local RayEnd = CFrame.lookAt(HumRoot.Position, Target.Position)
local RayParams = RaycastParams.new()
RayParams.FilterDescendantsInstances = Character:GetDescendants()
RayParams.FilterType = Enum.RaycastFilterType.Blacklist
local RayResult = workspace:Raycast(RayStart,RayEnd.LookVector * 10,RayParams) --- I used lookVector

Say is your way better or is mine?
Not sure if either is “better” but my brain is telling me that your CFrame.lookAt is slightly more work. Mine’s probably how someone at Roblox would do it and it looks a lot cleaner to me, but I’m bias
Hhm, Okay thanks for the help everyone. i think ill stick to mine since it’s already typed 
, who should i set to solutions?
bcus the target.Position is prob nil make sure that the variable target is the target’s Humanoidrootpart and make sure HumRoot is your root part
It’s good I fixed it Maji, although that probably was the problem
