AddForce和velocity有什么区别

velocity直接修改物体的速度，无视各种外力

addforce直接模仿物理受力了，给物体施加一个力，也会收到其他力的作用

下面是实验的代码：

pragma strict

//发射点

var FirePonit:Transform;

var FirePonit1:Transform;

//子弹

var Bullet:Rigidbody;

var Bullet1:Rigidbody;

private var clone:Rigidbody;

private var clone1:Rigidbody;

function Start () {

//实例化

clone=Instantiate(Bullet,FirePonit.position,FirePonit.rotation);

//实例化

clone1=Instantiate(Bullet1,FirePonit1.position,FirePonit1.rotation);

}

function Update () {

//向前运动

clone.velocity=transform.TransformDirection(Vector3.forward2); //向前运动

clone1.AddForce(Vector3.forward100);

Debug.Log(clone.velocity.z+"----"+clone1.velocity.z);

}
