position | Center of the sphere. |
radius | Radius of the sphere. |
layerMask | A Layer mask defines which layers of colliders to include in the query. |
queryTriggerInteraction | Specifies whether this query should hit Triggers. |
Collider[] Returns an array with all colliders touching or inside the sphere.
Computes and stores colliders touching or inside the sphere.
Additional resources: Physics.AllLayers. Allocates memory. Consider using Physics.OverlapSphereNonAlloc instead.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void ExplosionDamage(Vector3 center, float radius) { Collider[] hitColliders = Physics.OverlapSphere(center, radius); foreach (var hitCollider in hitColliders) { hitCollider.SendMessage("AddDamage"); } } }
