function ClosestPointOnBounds (position : Vector3) : Vector3

Description

The closest point to the bounding box of the attached collider.

This can be used to calculate hit points when applying explosion damage.

var hitPoints = 100.0;
function ApplyHitPoints (explosionPos : Vector3, radius : float) {
// The distance from the explosion position to the surface of the rigidbody
var closestPoint = collider.ClosestPointOnBounds(explosionPos);
var distance = Vector3f.Distance(closestPoint, explosionPos);

// The hit points we apply fall decrease with distance from the hit point
var hitPoints = 1.0 - Mathf.Clamp01(distance / radius);

// This is the final hitpoints we want to apply. 10 at maximum
hitPoints *= 10;
