JavaScript => public var point: Vector2;
C# => public Vector2 point;

Description 描述

The point in world space where the ray hit the collider's surface.

在世界坐标空间，射线碰到碰撞器表面的点。

The exact point of contact can be useful for positioning graphic effects (such as explosion or blood splatters) and for determining which specific part of an object was hit.

接触的确切点可用来定位特效（比如爆炸或血液飞溅）以及确定特定对象被击中部分。

JavaScript:

#pragma strict
public var direction;
function Update() {
	//Cast a ray in the direction specified in the inspector.
	var hit = Physics2D.Raycast(this.gameObject.transform.position, direction);
	//If something was hit.
	if (hit.collider != null) {
		//Display the point in world space where the ray hit the collider's surface.
		Debug.Log(hit.point);
	}
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour
{
	public Vector2 direction;
 
	void Update()
	{
		//Cast a ray in the direction specified in the inspector.
		RaycastHit2D hit = Physics2D.Raycast(this.gameObject.transform.position,direction);
 
		//If something was hit.
		if ( hit.collider != null )
		{
			//Display the point in world space where the ray hit the collider's surface.
			Debug.Log (hit.point);
		}
	}
