How do I make a simple wall climbing system for use with the Juke's Towers of Hell Kit?

Help and Feedback Scripting Support
#1

I would like to make a simple wall climbing system/custom client object for a JToH tower that allows the player to climb on certain walls.

I can’t seem to make sense of the scripts I’ve seen so I want to make a system that’s based on the JToH 5.4 kit and for it to be able to be scripted by a beginner/intermediate scripter like me.

I’ve tried using other people’s scripts and trying to port them over to the JToH kit.

You can achieve this by using raycasting to detect walls and setting the player’s movement accordingly.

Create a new LocalScript in StarterPlayerScripts and name it WallClimbing

My Approach

-- Constants
local RAYCAST_DISTANCE = 4
local MAX_CLIMB_ANGLE = 70

-- Variables
local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:WaitForChild("Humanoid")
local isClimbing = false

-- Raycast function
local function raycast(direction)
    local origin = character.HumanoidRootPart.Position
    local ray = Ray.new(origin, direction * RAYCAST_DISTANCE)
    local part, hitPosition, normal = workspace:FindPartOnRay(ray, character)
    return part, hitPosition, normal
end

-- Check if the player is facing a wall
local function checkForWall()
    local direction = character.HumanoidRootPart.CFrame.LookVector
    local part, _, normal = raycast(direction)
    if part and part.CanCollide and normal.Y < 0.2 then
        local angle = math.deg(math.acos(normal.Y))
        if angle <= MAX_CLIMB_ANGLE then
            return true
        end
    end
    return false
end

-- Climb up the wall
local function climbUp()
    isClimbing = true
    humanoid.PlatformStand = true
    while isClimbing and checkForWall() do
        local direction = character.HumanoidRootPart.CFrame.LookVector
        local _, hitPosition, normal = raycast(direction)
        local targetPosition = hitPosition + normal * 3
        local velocity = (targetPosition - character.HumanoidRootPart.Position) / 0.1
        character.HumanoidRootPart.Velocity = velocity
        wait(0.1)
    end
    isClimbing = false
    humanoid.PlatformStand = false
end

-- Detect if the player presses the spacebar while facing a wall
local function onInput(input, gameProcessed)
    if input.KeyCode == Enum.KeyCode.Space and not gameProcessed then
        if checkForWall() then
            climbUp()
        end
    end
end

-- Connect the input function to the UserInputService
game:GetService("UserInputService").InputBegan:Connect(onInput)

My approach works by checking if the player is facing a wall within a certain angle of MAX_CLIMB_ANGLE. If a wall is detected, the script enters a climbing state where the player’s PlatformStand property is set to true and the script constantly updates the player’s position to move them up the wall. They can exit the climbing state by releasing the spacebar or moving away from the wall.

Additionally, you can customize RAYCAST_DISTANCE and MAX_CLIMB_ANGLE constants to adjust the sensitivity of the system.

Thanks for the help! I’ll try and port this over to the JToH kit right away.
