Intro

ActionContext is a simpler, briefer, more memorable way to use ContextActionService through the use of object-oriented programming. It gives the concept of the context a first-class implementation in your code, groups actions together, and makes obvious when a context shared by multiple actions is entered/left.

Example​

local honkAction = {
    ActionName = "Honk",
    Inputs = { Enum.KeyCode.H, Enum.KeyCode.ButtonY },
    Handle = function (userInputState, inputObject)
        if userInputState == Enum.UserInputState.Begin then
            sound:Play()
        end
    end,
}
local actionContext = ActionContext.new({ honkAction })

-- Entering the car...
actionContext:Enter() 
-- ...and leaving it
actionContext:Leave()

Example (shorthand)​

ActionContext.new({ 
    ActionContext.actionBegin("Honk", { Enum.KeyCode.H }, function (inputObject)
        sound:Play()
    end)
 }):Enter()
