Part Will Not Face Me

lntPtr · July 30, 2023, 6:40pm

What I Want To Achieve: I want to make it so the wall part that is spawned in will turn and face the player.
The Issue: When I use the tool, the part spawned in is always in the same direction.
Solutions I have Tried: I have tried :Lerp, CFrame.LookAt, and LookVector

Client Code

local localPlayer = game:GetService("Players").LocalPlayer
local event = game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvents")["Combat"]["Wall"]
local clonedPart

script.Parent.RequiresHandle = false
script.Parent.Equipped:Connect(function()
	
	local hrp = script.Parent.Parent:WaitForChild("HumanoidRootPart")
	local part = Instance.new("Part")
	clonedPart = part
	part.Transparency = 0.8
	part.Parent = game:GetService("Workspace").CurrentCamera
	
	spawn(function()
		while clonedPart do
			local pos = hrp.Position + hrp.CFrame.LookVector*5 
			part.CFrame = CFrame.new(pos, hrp.Position) * CFrame.new(0,-2.5,0)
			task.wait(0.01)
		end
	end)
	
end)

script.Parent.Activated:Connect(function()
	
	if not clonedPart then return end
	local hrp = localPlayer.Character.HumanoidRootPart
	local pos = hrp.Position + hrp.CFrame.LookVector*5
	local ray = Ray.new(clonedPart.Position, Vector3.new(0, -0.5, 0))
	local _, _, _, material = workspace:FindPartOnRayWithWhitelist(ray, {workspace.Terrain})
	
	if material == Enum.Material.Air then return end
	if material == Enum.Material.Water then return end
	
	event:FireServer(clonedPart.Position, material, pos)
	clonedPart:Destroy()

Sorry for how long the scripts are, any help would be appreciated, thank you!

It’s because your create the cframe in world space you have to make it object space so it’s relative to your player’s humanoidrootpart

lntPtr · July 30, 2023, 7:54pm

So how would you fix this? I am quite confused. I read the documentation (at least when I searched it up I got this: 3D Workspace | Documentation - Roblox Creator Hub ) yet I am still quite confused on how to fix this.

astraIboy · July 30, 2023, 11:51pm

How about you try first making the part orient to the humanoidrootpart’s cframe and then do your offset calculations

lntPtr · July 30, 2023, 11:56pm

I will try that as soon as I can and let you know how it goes!

A few things I noticed in your script

CFrame.new() is a deprecated function, keep using CFrame.lookAt()
Use coroutines instead of spawn() - spawn is deprecated

coroutines allow for more flexibility

coroutine.wrap(function()

end)()

// As opposed to

spawn(function()

end)

NEVER a good idea to pass through positions to the server through a remote and rely on those - allows for easy exploitation.
Instead of using a While(true) loop and using task.wait() - which relies on the servers heartbeat, even better:
Get all the services at the top of the script (readability and reduce redundancies)

local RunService = game:GetService("RunService")

// This will be much smoother for the client
RunService.RenderStepped:Connect(function()
   // Do Work
end)

Now to answer your question:
The reason your part is always being placed in the same direction, is because you’re using .Position when you fire server.
Why is this a problem? .Position doesn’t take into account the orientation of an object.
If you want to have the object face your character, it’d probably be more reliable to get the CFrame of your characters primary part or root part like so: localPlayer.Character.PrimaryPart.CFrame.
As a result, you’ll need to change the code on your server where the .Position is also being set for the wall → Doing something like wallPart.CFrame = char.PrimaryPart.CFrame will fix your problem.

To conclude:

Here’s my solution:

wallPart.CFrame = plr.Character.PrimaryPart.CFrame

Where you are going wrong:

Setting the position of the wall like this:

wallPart.CFrame = CFrame.new(position)

is the same as:

wallPart.Position = position

Which won’t change the objects orientation at all.

Sorry if I got out of scope a little bit, was just pointing out some mistakes I used to make when I also started

Hello, Joel! Thank you so much for your response, it really did help a lot. I still have one slight problem though, using your code

wallPart.CFrame = plr.Character.PrimaryPart.CFrame

will still spawn it to the side of my character. However, it does face my character!

I tried to tweak it to the best of my ability and the closes I got was this code snippet right here,

wallPart.CFrame = plr.Character.PrimaryPart.CFrame + (plr.Character.PrimaryPart.CFrame.LookVector * 5)

I do not know if this is the model issue or if I can some how fix this within my script, my friend is the modeller not me and he is currently on a vacation!

P.S. I do really appreciate your detailed response. I am currently trying to implement all the changes that you recommended to me!

TheAnimeDev28 · July 31, 2023, 10:08pm

Hey! Sorry for the late response, just got off of work not too long ago.

I noticed the primary problem with your script happens to be that the object is not properly rotated

wallPart.CFrame = plr.Character.PrimaryPart.CFrame * (plr.Character.PrimaryPart.CFrame.LookVector * 20) * CFrame.Angles(0,math.rad(90),0)

This will offset the part 20 studs in front of the players character and rotate it 90 degrees about the Y axis.

Or you can approach it like this (once you understand world + object space will be a lot more readable than my previous solution):

wallPart.CFrame = wallPart.CFrame:ToWorldSpace(CFrame.new(0,0,20)) * CFrame.Angles(0,math.rad(90),0)

The two code blocks I sent should be equivalent in functionality.

But does CFrame.Angles do? A CFrame constructor that helps you create precise rotations.
What does math.rad do? math.rad(90) = 90 degrees

Note that rad stands for radians, and math.rad(90) will convert degrees to radians.

No worries about late responses, I do the same too. I am still kinda lost, it won’t work. I even implemented some of my own changes but nothing got close to it. The main issue with the first one is that it keeps throwing me an error about Vector since I have to change the multiplication sign to a plus sign for the radians. The second just spawns it in the middle of no where and doesn’t face you. I am kinda lost on what to do next.

TheAnimeDev28 · August 1, 2023, 1:53am

I see, I probably wrote down the order of the multiplications wrong for the first one. Still happens to me all the time haha.

An easy solution would be to go to the wallParts properties, and change the pivot point orientation of the wallPart to be 0,90,0 → Or if there is already a rotation, just add or subtract 90 from it. Should get the same effect without having to worry about multiplying the extra CFrame!

lntPtr · August 1, 2023, 3:36am

Thank you so much! Thank you for being patient, giving me tips on how to improve my actual code, and fixing my issue. I did what you said and did the orientation and with these two lines I fixed it.

wallPart.CFrame = plr.Character.PrimaryPart.CFrame + (plr.Character.PrimaryPart.CFrame.LookVector * 5)
wallPart.CFrame = wallPart.CFrame:ToWorldSpace(CFrame.new(0,0,0)) * CFrame.Angles(0,math.rad(90),0)

Thank you so much, I appreciate it a lot.
