Mobile

Spark allows you to activate an action manually. This is especially useful to implement mobile touch controls.

For buttons, you can activate an action with Actions:hold. Here's how you might implement a mobile button:

local imageButton = Instance.new("ImageButton")

local hold = nil

imageButton.InputBegan:Connect(function(inputObject)
    if inputObject.UserInputState ~= Enum.UserInputState.Begin then
        -- UserInputState will be Change if the touch was dragged onto the button.
        return
    end

    -- You can either check if inputObject.UserInputType == Enum.UserInputType.Touch or hide
    -- the button when touch isn't being used.

    if hold == nil then
        hold = {
            -- The hold method acts like a button press. It returns a function to stop the press.
            stopHold = actions:hold("attack"),
            inputObject = inputObject,
        }
    end
end)

imageButton.InputEnded:Connect(function(inputObject)
    -- Only stop the hold if it's the same touch that started it.
    if hold ~= nil and hold.inputObject == inputObject then
        hold.stopHold()
        hold = nil
    end
end)

For 2D axis values like movement or camera movement, use Actions:move.

local thumbstickDirection = Vector2.one -- Get this value from your thumbstick.

-- This will increase the 2D axis value of the move action by thumbstickDirection.
-- It's reset every time `Actions:update` is called, so you need to call it every frame.
actions:move("move", thumbstickDirection)
