Okay well there really is no SET thing wear it goes so I copied it off the Wiki, read a little and made this. What I want to do is send a ray from the Person's torso straight to wear they are faceing. "Not a player"

]
local ray = Ray.new(
script.Parent.Torso.Position,
script.Parent.Torso.Position + Vector3.new()-- What do I put here?
)

Okay so I have this and how do I tell if the ray Hits a part?

local ray = Ray.new(
Torso.Position,
Torso.Position + Torso.CFrame.lookVector*distance
)
local block, endPoint = Workspace:FindPartOnRay(ray)

Ray.new is a function that takes 2 arguments: start position (Vector3) and direction (Vector3)

In this case, direction's magnitude is the length it travels.

In your script, the block is if it hits a part, so:
if block then
print("It hit: ", block)
end

@evolved

I wasn't showing the whole CFrame part of it, only the second half. And even if I was doing that adding a comma wouldn't work.

local cf = part.Position
CFrame.new(cf.p, cf.p + cf.lookVector)

Okay well it wasn't printing so I was thinking it wasn't working because I didn't set a distance.

This is what I have, I changed block to part because it might be easier to use the wiki.


local ray = Ray.new(
Torso.Position,
Torso.CFrame.lookVector
)
local part, endPoint = Workspace:FindPartOnRay(ray)
if part then
print("it hit:", part)
end

"Torso.CFrame.lookVector"
It is going 1 stud, from the center, so the chances of hitting anything are very low

Okay one question. Can anyone calculate how many studs someone can move at a walk speed of 10?

Thats how they did it? That will make this a lot easier to calculate with the speed of the person. AKA running.

well speed = distance/time
So if you want to get the distance they go in given time and speed (assuming this is constant)

distance = speed * time
distance = 10 studs/second * 5 seconds
distance = 50 studs

Okay so the walking away from the part is not working..

I have this and I had no idea what I was doing when I made it.. which was like 3 minutes ago. "block is the part that the humanoid moves to"


block.CFrame = Torso.CFrame - Torso.CFrame.lookVector*-Dis

What is block? Are you trying to set it in front of the torso, if so:
block.CFrame = Torso.CFrame * CFrame.new(0, 0, -Distance)

In the random movment script that I made 90% of and the other is from scripting helpers 'Thank you'


Anyway It makes a brick, moves it to a random position with a givent distance, than I move the humanoid it it and remove the block and do it over that over.

Anyway the part the humanoid moves to is block.

Alright, so is there a problem?
You should probably place it at random.

Block.CFrame = Torso.CFrame * CFrame.new(math.random(-50, 50), 0, math.random(-50, 50))

No I mean it is placed random but I want it to be places the opposite the torso is facing if a part is within a certain distance.
