Question

JavaScript => public function AddExplosionForce(explosionForce: float, explosionPosition: Vector3, explosionRadius: float, upwardsModifier: float = 0.0F, mode: ForceMode = ForceMode.Force): void;

C# => public void AddExplosionForce(float explosionForce, Vector3 explosionPosition, float explosionRadius, float upwardsModifier = 0.0F, ForceMode mode = ForceMode.Force);

Parameters 参数

explosionForce	The force of the explosion (which may be modified by distance). 爆炸力，可以通过距离来修改
explosionPosition	The centre of the sphere within which the explosion has its effect. 球体的中心。
explosionRadius	The radius of the sphere within which the explosion has its effect. 球体的半径，在半径内才有爆炸效果。
upwardsModifier	Adjustment to the apparent position of the explosion to make it seem to lift objects. 调节爆炸出现的位置，使其看起来像掀起对象。
mode	The method used to apply the force to its targets. 用于应用到目标力的方式。

Description 描述

Applies a force to a rigidbody that simulates explosion effects.

应用一个力到刚体来模拟爆炸效果。

The explosion is modelled as a sphere with a certain centre position and radius in world space; normally, anything outside the sphere is not affected by the explosion and the force decreases in proportion to distance from the centre. However, if a value of zero is passed for the radius then the full force will be applied regardless of how far the centre is from the rigidbody.

爆炸是一个具有中心点和半径的球体，在世界坐标空间；一般情况下，在球体外的任何东西都不会受到爆炸的影响并且力从中心到外按比例减小。然而，如果半径为0，那么力完全应用到刚体，而不管距离中心有多远。

By default, the direction of the force is the line going from the explosion centre to the rigidbody's centre of mass. If you pass a non-zero value for the upwardsModifier parameter, the direction will be modified by subtracting that value from the Y component of the centre point. For example, if you pass a value of 2.0 for upwardsModifier, the explosion will appear to be centred 2.0 units below its actual position for purposes of calculating the force direction (ie, the centre and the radius of effect are not modified). Using this parameter, you can easily make the explosion appear to throw objects up into the air, which often gives a more dramatic effect than a simple outward force.

默认，从爆炸中心到刚体的质量中心力的方向是线性。如果你upwardsModifier参数传递非0值，该方向将通过减去中心点Y轴的值修改。例如，如果upwardsModifier的值为2.0，那么该爆炸出现在实际位置中心点2单位下（如，中心和影响的半径不会被修改）。使用这个参数，你可以很容易地使爆炸似乎把物体扔到空中，这往往比单纯的外力更具戏剧性的效果。

Force can be applied only to an active rigidbody. If a GameObject is inactive, AddExplosionForce has no effect.

力仅应用于激活的刚体。如果游戏对象未激活，AddExplosionForce也将无效。

JavaScript:

#pragma strict
// Applies an explosion force to all nearby rigidbodies
public var radius: float = 5.0F;
public var power: float = 10.0F;
function Start() {
	var explosionPos: Vector3 = transform.position;
	var colliders: Collider[] = Physics.OverlapSphere(explosionPos, radius);
	for (var hit: Collider in colliders) {
		var rb: Rigidbody = hit.GetComponent.<Rigidbody>();
		if (rb != null)
			rb.AddExplosionForce(power, explosionPos, radius, 3.0F);
	}
}

C#:

using UnityEngine;
using System.Collections;
 
// Applies an explosion force to all nearby rigidbodies
public class ExampleClass : MonoBehaviour {
    public float radius = 5.0F;
    public float power = 10.0F;
 
    void Start() {
        Vector3 explosionPos = transform.position;
        Collider[] colliders = Physics.OverlapSphere(explosionPos, radius);
        foreach (Collider hit in colliders) {
            Rigidbody rb = hit.GetComponent<Rigidbody>();
 
            if (rb != null)
                rb.AddExplosionForce(power, explosionPos, radius, 3.0F);
 
        }
    }
}
