Wallclimb system help

talis783 · January 2, 2025, 10:12pm

Please watch the video for what im explaining to make any sense: https://youtu.be/ZuV0_p4GLaE

Anyways as you can see in the video i have a wallclimb system which is not great but for my first time doing something like that im happy with it, it allows for you to switch walls while climbing. However as you can see that only works if the wall is directly to the right or left of the players root part. I would like to be able to switch walls in the second scenario shown in the video too. I am new to humanoid movers and dont know how to raycast in such a way to allow for what I want

local sript

local flyEvent = game.ReplicatedStorage:WaitForChild("Wall")
local UIS = game:GetService("UserInputService")

local RS = game:GetService("RunService")

local RParams = RaycastParams.new()
RParams.FilterType = Enum.RaycastFilterType.Exclude

local nearWall = false

UIS.InputBegan:Connect(function(input, gp)
	if gp or nearWall == false then return end
	
	if input.KeyCode == Enum.KeyCode.W then
		flyEvent:FireServer("Up", true)
	end
	
	if input.KeyCode == Enum.KeyCode.D then
		
		flyEvent:FireServer("Right", true)
	end
	
	if input.KeyCode == Enum.KeyCode.A then
		
		flyEvent:FireServer("Left", true)
	end
	
	if input.KeyCode == Enum.KeyCode.S then
		flyEvent:FireServer("Down", true)
	end

end)

UIS.InputEnded:Connect(function(input, gp)
	if gp or nearWall == false then return end

	if input.KeyCode == Enum.KeyCode.W then
		flyEvent:FireServer("Up", false)
	end

Bumping as I still need help with this

Doomcolp · January 2, 2025, 11:10pm

Sorry that this initial reply isn’t helpful but im pretty sure you’re trying to detect a wall adjacent to the one you’re currently on right?

(for the second scenario)

talis783 · January 2, 2025, 11:11pm

As it’s shown in the video, yes I need to detect that wall using raycasts and position the player on it

Doomcolp · January 2, 2025, 11:36pm

Okay so if you have a wall that is adjacent, it should be able to hit if you raycast in the direction of the LeftVector / RightVector of the wall the player is on from the wall’s position.

also sorry for the long wait. I had to really sit and think about how to solve this lol

so…

Raycast from the wall the player is currently on
Have 2 ray casts, one going left, one going right (LeftVector, RightVector)
Check if the ray hit anything, and if it is a valid surface

I’ve honestly got no idea what im talking about so if anyone more knowledgeable sees this, could you correct me?

talis783 · January 2, 2025, 11:49pm

Does not work. cant send the video because its too large but the character just randomly rotates and never switches walls correctly

Doomcolp · January 2, 2025, 11:51pm

Yikes I hoped that would work. Can I go around and look for posts on this?

talis783 · January 2, 2025, 11:52pm

I looked at just about every post about wallclimbing and none of them really helped me in the issue that I have. They all explain how to do just up down left right which I have working, none of them address the issue with changing walls that I have

Doomcolp · January 3, 2025, 12:01am

I don’t really have any other guesses other than rotating the position you’re raycasting from by 90deg and -90deg and moving it a little bit in that direction.

Hopefully some1 else can help

talis783 · January 3, 2025, 12:03am

I tried that and the raycast’s did work but the player would never be orientated properly to the wall that it hit

Doomcolp · January 3, 2025, 12:04am

Couldn’t you make the character LookAt the wall that they’re climbing to?

Like

Char.HumanoidRootPart:LookAt(TheWall)

it detects the wall but i dont get aligned properly

Doomcolp · January 3, 2025, 1:06am

again I’m sorry for the late response (I forgot to check again). You might have to manually position the character like CFrame addition.

(My next response prolly gonna be delayed by an hour lol)

HumanoidRootPart.CFrame += CFrame.new(…)

talis783 · January 3, 2025, 1:16am

Can you work that into the script I dont know how to position it correctly i tried it wasnt right

Doomcolp · January 3, 2025, 4:20am

im REALLY SORRY about delaying a response for 3 hours!! Completely forgot again

to

--[[ spaced out
so you can see
the change(s)
I made
]]

humanoidRootPart.CFrame = CFrame.new(humanoidRootPart.Position,
humanoidRootPart.Position
+ -rayCastResultFrontRight.Normal
+ Vector3.new(10, 0, 0)
)

I chose (10, 0, 0) to move your character to the right a bit (hopefully I’m not tripping today)

So if I were you, I would just experiment with the numbers. But I’m pretty sure there’s a better way to make this type of thing if somebody who’s made one could come around

talis783 · January 3, 2025, 4:51am

Tried it, does not work. You can stop wasting your time here I gave up on it a while ago before you responded anyways

Doomcolp · January 3, 2025, 4:55am

Alright. Sorry about wasting your day btw

talis783 · January 3, 2025, 5:17am

You didn’t waste my time its just theres no point trying I cant get it to work i spent days

Doomcolp · January 3, 2025, 5:24am

Hey well if you’re willing to, maybe you could look at an open sourced project and try to learn from that?

talis783 · January 3, 2025, 5:25am

Tried around 6. none of them had they all either didn’t have what I needed or just didn’t work
