Rigidbody.AddRelativeForce 添加相对力

function AddRelativeForce (force : Vector3, mode : ForceMode = ForceMode.Force) : void

Description描述

Adds a force to the rigidbody relative to its coordinate system.

添加一个力到刚体。相对于它的系统坐标。

As a result the rigidbody will start moving.

作为结果刚体将开始移动。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void FixedUpdate() {
		rigidbody.AddRelativeForce(Vector3.forward * 10);
	}
}

// Moves the rigidbody forward along its own z-axis
//移动刚体向前沿着他自己的z轴

function FixedUpdate () {
	rigidbody.AddRelativeForce (Vector3.forward * 10);
}

• function AddRelativeForce (x : float, y : float, z : float, mode : ForceMode = ForceMode.Force) : void

Description描述

Adds a force to the rigidbody relative to its coordinate system.

添加一个力到刚体。相对于它的系统坐标。

As a result the rigidbody will start moving.

作为结果刚体将开始移动。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void FixedUpdate() {
		rigidbody.AddRelativeForce(0, 0, 10);
	}
}

// Moves the rigidbody forward along its own z-axis
//移动刚体向前沿着他自己的z轴

function FixedUpdate () {
	rigidbody.AddRelativeForce (0, 0, 10);
}

If you want to apply a force over several frames you should apply it inside FixedUpdate instead of Update.

如果你想在多帧中应用力，你应该在FixedUpdate中而不是Update使用使用它。
