JavaScript => public static function Linecast(start: Vector3, end: Vector3, layerMask: int = DefaultRaycastLayers): bool;
C# => public static bool Linecast(Vector3 start, Vector3 end, int layerMask = DefaultRaycastLayers);

Description 描述

Returns true if there is any collider intersecting the line between start and end.

在线的开始和结束位置之间，如果与任何碰撞器相交返回真。

JavaScript:

	var target : Transform;
	function Update () {
		if (!Physics.Linecast (transform.position, target.position)) {
			//ProcessData.AndDoSomeCalculations();
		}
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Transform target;
    void Update() {
        if (!Physics.Linecast(transform.position, target.position)) {
        }
    }
}

Layer mask is used to selectively ignore colliders when casting a ray.

Layer mask是用来指定投射的层。

JavaScript => public static function Linecast(start: Vector3, end: Vector3, out hitInfo: RaycastHit, layerMask: int = DefaultRaycastLayers): bool; C# => public static bool Linecast(Vector3 start, Vector3 end, out RaycastHit hitInfo, int layerMask = DefaultRaycastLayers);

Description 描述

Returns true if there is any collider intersecting the line between start and end.

在线的开始和结束位置之间，如果与任何碰撞器相交返回真。

If true is returned, hitInfo will contain more information about where the collider was hit (See Also: RaycastHit). Layer mask is used to selectively ignore colliders when casting a ray.

如果返回true，hitInfo返回碰到的RaycastHit信息。Layer mask是用来指定投射的层。 Physics
