Hierarchy Active State Auto-Save

In dynamic Unity levels, objects are frequently deactivated (e.g., picked-up coins, opened doorways, completed quest triggers) rather than completely destroyed. When a scene is re-entered or a game slot is loaded, you must restore whether each of these game objects was visible/active or hidden.

Save System Pro provides AutoSaveActiveState to automate this tracking cleanly.

🤖 What does it track?

When attached, the script tracks:

• GameObject Active State (bool): Specifically the gameObject.activeSelf property.

⚙️ Drag-and-Drop Setup

To automate hierarchy visibility tracking:

1. Select the dynamic target GameObject.
2. Ensure it has an AutoSaveIdentifier component attached.
3. Click Add Component in the Inspector.
4. Search for and select AutoSaveActiveState.

🚀 Active-State Deactivation Gotcha & Solutions

In Unity, if a parent object or the object containing your tracking script is set to inactive (activeSelf = false), its update cycles, start loops, and standard monobehaviour methods stop running completely.

This presents a critical save-system challenge: How can an inactive script save itself when it cannot execute logic?

Save System Pro solves this using two layered architectural safety nets:

1. Central Registration with AutoSaveManager

On startup, AutoSaveActiveState registers itself with the central AutoSaveManager while it is active. When a save is triggered, the AutoSaveManager queries the registered list directly—even if the target GameObjects are currently inactive—and writes their visibility status to disk.

2. Manual Trigger Integration

If you deactivate objects dynamically during runtime, the script will write its state to the active slot’s Key-Value database immediately on deactivation:

private void OnDisable()
{
    // Write state immediately to secure backup before script sleeps
    SaveActiveState();
}

This guarantees that even if the client crashes or loses power, the deactivated status of your game chest, key item, or coins remains perfectly recorded!
