🔹 What is it?

• A Roblox service that lets you detect key presses, mouse clicks, or gamepad buttons.
• Works for keyboard, touch, and gamepad inputs.
• Useful for things like jumping, attacking, or opening menus.

🔹 How to get it

local ContextActionService = game:GetService("ContextActionService")

🔹 Bind a key to do something

local function onEPressed(actionName, inputState, inputObject)
    if inputState == Enum.UserInputState.Begin then
        print("E was pressed!")
    end
end

ContextActionService:BindAction("PrintMessage", onEPressed, false, Enum.KeyCode.E)

Explanation:

• "PrintMessage" → name of this action.
• onEPressed → function that runs when E is pressed.
• false → don’t create a mobile touch button.
• Enum.KeyCode.E → the key to bind.

🔹 Unbind a key

ContextActionService:UnbindAction("PrintMessage")

• Stops the function from running when the key is pressed.
