Physics.OverlapSphere

static function OverlapSphere (position : Vector3, radius : float, layerMask : int = kAllLayers) : Collider[]

Description

Returns an array with all colliders touching or inside the sphere.

NOTE: Currently this only checks against the bounding volumes of the colliders not against the actual colliders.

JavaScript
    // Call a damage function on all objects caught in the
// radius of an explosion.
function ExplosionDamage(center: Vector3, radius: float) {
var hitColliders = Physics.OverlapSphere(center, radius);

for (var i = 0; i < hitColliders.Length; i++) {
hitColliders[i].SendMessage("AddDamage");
}
}
