Detecting if a character is walking downhill

This small code snippet lets you know when a player is walking downhill. It works by watching the player’s position and checking if they are moving down without jumping.

To use this code:

  1. Place in a local script in Game > StarterPlayer > StarterPlayerScripts
  2. Paste code provided.

Code:

-- Define the local player and the character they control
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")

-- Store the previous position of the character's HumanoidRootPart
local prevPosition = character.HumanoidRootPart.Position

-- Function to check if the character is moving downhill
local function checkDownhill()
    -- Get the current position of the character's HumanoidRootPart
    local currPosition = character.HumanoidRootPart.Position

    -- If the character's Y position is lower than the previous position
    -- and the character's vertical movement direction is zero,
    -- then the character is walking downhill
    if currPosition.Y < prevPosition.Y and humanoid.MoveDirection.Y == 0 then
        print("Walking downhill")  -- Print a message to the console
    end

    -- Update the previous position with the current position
    prevPosition = currPosition
end

-- Connect the checkDownhill function to the Heartbeat event of the RunService,
-- so it's checked every frame
game:GetService("RunService").Heartbeat:Connect(checkDownhill)
