Transform.forward 向前

# [Transform](Transform.html).forward 向前

var *forward* : [Vector3](../Vector3/Vector3.html)

*Description* 描述

The blue axis of the transform in world space.

在世界空间坐标变换的蓝色轴。也就是 z 轴。

* [C#](#)
* [JavaScript](#)

```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public void Awake() {
		rigidbody.velocity = transform.forward * 10;
	}
}
```

```
// Set's the rigidbody velocity to be
// along the blue axis of the transform
//设置刚体的速度沿着物体的蓝色轴移动
rigidbody.velocity = transform.forward * 10;
```

另一个例子：

* [C#](#)
* [JavaScript](#)

```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public float angleBetween = 0.0F;
	public Transform target;
	void Update() {
		Vector3 targetDir = target.position - transform.position;
		angleBetween = Vector3.Angle(transform.forward, targetDir);
	}
}
```

```
// Computes the angle between the target transform and this object
//计算目标变换和这个物体之间的角度
var angleBetween = 0.0;
var target : Transform;
function Update () {
	var targetDir = target.position - transform.position;
	angleBetween = Vector3.Angle (transform.forward, targetDir);
}
```
