NetPadButton

The NetPadButton class is a networked controller component that captures and synchronizes button states between a client device and a server. It inherits from NetPadClientController<ButtonMessage> and implements Unity's pointer event interfaces for UI interaction.

Configuration

Identifier: A unique string to identify different button instances. Use this to differentiate between multiple buttons on the same controller (e.g., "JumpButton", "FireButton").

Core Methods

• Reset(): Initializes the button component reference when the script is applied to a GameObject

• Awake(): Ensures the button component reference is properly set up

• IsSupported(): Always returns true (button functionality is universally supported)

• UpdateData(ButtonMessage message): Updates the ButtonMessage with current button state

• HasChanged(): Determines if the button state has changed since last update

Unity UI Integration

NetPadButton implements Unity's pointer event interfaces:

• IPointerDownHandler: OnPointerDown(PointerEventData eventData)

  • Triggered when pointer/finger presses down on the button

  • Sets button state to ButtonState.Down

  • Immediately sends update to server

• IPointerClickHandler: OnPointerClick(PointerEventData eventData)

  • Triggered when pointer is released on the same button (complete click)

  • Sets button state to ButtonState.Up

  • Sends final button state to server

• IPointerUpHandler: OnPointerUp(PointerEventData eventData)

  • Triggered when pointer is released (even if dragged outside button)

  • Resets button state to ButtonState.None if released outside button area

  • Ensures proper state cleanup

Button States

• None: Default state, button not being interacted with

• Down: Button is currently pressed down

• Up: Button was just released (single frame state)

Server Access

Access button states on the server side via:

// Get specific button by identifier
var jumpButton = player.Input.GetButton("JumpButton");
if (jumpButton.IsDown)
{
    // Handle button press
}

// Or check button state directly
if (player.Input.GetButtonDown("FireButton"))
{
    // Handle button down event
}

Usage Tips

• Attach to any GameObject with a Button or UI element

• Set unique identifiers for each button to distinguish them on the server

• Button state changes are sent immediately for responsive gameplay

• Works with both touch and mouse input through Unity's event system
