Fast Contract

• Namespace: XmobiTea.ObserverType
• Write with notification: SetValue(value)
• Silent write: SetValueWithoutNotify(value)
• Read: GetValue() or implicit cast
• Event: onValueChanged
• SetValue(...) always invokes listeners, even for unchanged values.
• Inspector edits are silent. ++ and -- are silent where those operators exist.
• ObserverCustom<T> has no dedicated custom property drawer.

Minimal Example

using UnityEngine;
using XmobiTea.ObserverType;

public sealed class ScoreView : MonoBehaviour
{
    [SerializeField] private ObserverInt score = new ObserverInt();

    private void Awake()
    {
        score ??= new ObserverInt();
        score.onValueChanged.AddListener(OnScoreChanged);
    }

    private void OnDestroy()
    {
        if (score != null)
            score.onValueChanged.RemoveListener(OnScoreChanged);
    }

    public void AddScore(int amount)
    {
        score.SetValue(score.GetValue() + amount);
    }

    private void OnScoreChanged(int value)
    {
        Debug.Log(value);
    }
}
