Rigidbody.ClosestPointOnBounds 到边界框的最近点

烟雨

//到附加的碰撞器边界框上的最近点。

//这可以用来计算受到爆炸伤害时的伤害点数。或计算作用到刚体表面上一个点的爆炸力。

var hitPoints : float = 10.0;

function ApplyHitPoints (explosionPos : Vector3, radius : float) {

// The distance from the explosion position to the surface of the rigidbody

//从爆炸位置到刚体表面的距离

var closestPoint : Vector3 = rigidbody.ClosestPointOnBounds(explosionPos);

var distance : float = Vector3.Distance(closestPoint, explosionPos);

// The hit points we apply fall decrease with distance from the hit point

//伤害点数随着到伤害的距离而降低

var damage : float = 1.0 - Mathf.Clamp01(distance / radius);

// This is the final hitpoints we want to apply. 10 at maximum.

//这是我们要用的最终伤害点数。

damage *= 10;

// Apply the damage

//应用伤害

hitPoints -= damage;
