HookUIManager API

The HookUIManager is the singleton that orchestrates the entire system.

Note: While HookUI is designed to work without code, you can drive it entirely from code if you wish.

Accessing the Instance​

HookUIManager.Instance

Core Methods​

Initialize()​

Starts the flow inside a coroutine, jumping to the definition of the Start Node in the Graph.

  • Usually called automatically if "Initialize On Start" is checked in the Inspector.

TransitionToScreen(ScreenNodeData node, bool isBackMove)​

  • Internal usage mostly, but can be used to force a jump.
  • Handles Show()/Hide() logic.

GoBack()​

Pops the navigation history stack and returns to the previous screen.

HookUIManager.Instance.GoBack();

OnButtonPressed(string buttonID)​

Simulates a button press. Useful if you have a physical button or keyboard input that should trigger a UI navigation event.

if (Input.GetKeyDown(KeyCode.Escape))
{
    // Simulate pressing the "Back" button ID
    HookUIManager.Instance.OnButtonPressed("Back");
}

Events​

  • OnNavigatedToNodeID: Subscribe to know whenever the screen changes.
HookUIManager.Instance.OnNavigatedToNodeID += (nodeID) => {
    Debug.Log($"We just arrived at: {nodeID}");
};
