"just use Enum.RaycastFilterType.Exclude and Enum.RaycastFilterType.Include?"

I apologize for the confusion, but there seems to be a misunderstanding. The Enum.RaycastFilterType in Roblox does not have Exclude or Include as options. The correct options are Blacklist and Whitelist.

Here is the corrected script with the correct enumeration:

```lua
-- local script for climbing system 
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local lastJumpTime = 0
local isClimbing = false

local function onJumpRequest()
    local currentTime = tick()
    if currentTime - lastJumpTime < 0.3 then -- double press space
        local camera = workspace.CurrentCamera
        local rayOrigin = camera.CFrame.Position
        local rayDirection = camera.CFrame.LookVector * 10
        local raycastParams = RaycastParams.new()
        raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
        raycastParams.FilterDescendantsInstances = {character}
        raycastParams.IgnoreWater = true
        local raycastResult = workspace:Raycast(rayOrigin, rayDirection, raycastParams)
        
        if raycastResult and raycastResult.Instance then
            humanoid:ChangeState(Enum.HumanoidStateType.Climbing)
            isClimbing = true
        end
    end
    lastJumpTime = currentTime
end

local function onRenderStepped()
    if isClimbing then
        local camera = workspace.CurrentCamera
        local rayOrigin = camera.CFrame.Position
        local rayDirection = camera.CFrame.LookVector * 10
        local raycastParams = RaycastParams.new()
        raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
        raycastParams.FilterDescendantsInstances = {character}
        raycastParams.IgnoreWater = true
        local raycastResult = workspace:Raycast(rayOrigin, rayDirection, raycastParams)
        
        if not raycastResult or not raycastResult.Instance then
            humanoid:ChangeState(Enum.HumanoidStateType.Running)
            isClimbing = false
        end
    end
end

UserInputService.JumpRequest:Connect(onJumpRequest)
RunService.RenderStepped:Connect(onRenderStepped)
```
This script should be placed in a LocalScript within the player's character or a GUI. It listens for double spacebar presses to initiate climbing and uses raycasting to determine if the player's camera is facing a climbable surface. The climbing state is maintained while the player is facing the surface and is stopped when they look away.
