Hider Visibility Events

To run gameplay logic when a revealer sees or loses sight of a hider, subscribe to the revealer's OnHiderVisibilityChanged event.

OnHiderVisibilityChanged

public event Action<FogOfWarHider, bool> OnHiderVisibilityChanged

On a FogOfWarRevealer. The first parameter is the hider in question; the second is its new visibility (true = now seen, false = lost). The event fires from the perspective of that specific revealer.

Example

using FOW;
using UnityEngine;

[RequireComponent(typeof(FogOfWarRevealer))]
public class SightReporter : MonoBehaviour
{
    FogOfWarRevealer revealer;

    void OnEnable()
    {
        revealer = GetComponent<FogOfWarRevealer>();
        revealer.OnHiderVisibilityChanged += HandleVisibility;
    }

    void OnDisable()
    {
        revealer.OnHiderVisibilityChanged -= HandleVisibility;
    }

    void HandleVisibility(FogOfWarHider hider, bool isVisible)
    {
        if (isVisible)
            Debug.Log($"{name} spotted {hider.name}");
        else
            Debug.Log($"{name} lost sight of {hider.name}");
    }
}

Sample Script

A ready-made example, DrawLineToHiderOnReveal.cs, ships with the package and demonstrates this event by drawing a line from a revealer to each hider it sees. See it in Demo 01 (Pixel-Perfect) — enable the SampleCharacter/Eye/Draw Line To Hider GameObject.

Hider-Side Events

To react to a hider's overall visibility (across all revealers) instead, use the hider's OnActiveChanged event, or attach a Hider Behavior.
