Question

JavaScript => public static function CapsuleCastAll(point1: Vector3, point2: Vector3, radius: float, direction: Vector3, maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): RaycastHit[] ;

C# => public static RaycastHit[] CapsuleCastAll(Vector3 point1, Vector3 point2, float radius, Vector3 direction, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters 参数

point1	The center of the sphere at the start of the capsule. 球体开始中心点。
point2	The center of the sphere at the end of the capsule. 球体结束的中心点。
radius	The radius of the capsule. 胶囊的半径。
direction	The direction into which to sweep the capsule. 胶囊扫描的方向。
maxDistance	The max length of the sweep. 扫描的最大长度。
layerMask	A Layer mask that is used to selectively ignore colliders when casting a capsule. 选择投射的层蒙版。
queryTriggerInteraction	Specifies whether this query should hit Triggers. 指定是否查询碰到触发器。

Returns 返回值

RaycastHit[] An array of all colliders hit in the sweep.

返回扫描到的所有碰撞器RaycastHit信息。

Description 描述

Like Physics.CapsuleCast, but this function will return all hits the capsule sweep intersects.

像Physics.CapsuleCast，但这个函数将返回所有胶囊扫描交叉碰到的对象。

Casts a capsule against all colliders in the scene and returns detailed information on each collider which was hit. The capsule is defined by the two spheres with radius around point1 and point2, which form the two ends of the capsule. Hits are returned all colliders which would collide against this capsule if the capsule was moved along direction. This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way.

投射一个胶囊针对场景中所有碰撞器，并返回所有碰到的每个碰撞器的细节信息。 胶囊是由point1和point2位置的两个球带有radius半径形成胶囊的两端定义。返回胶囊沿direction方向碰到的第一个碰撞器。这通常用于投射不需足够的精度，因为你要找出一个特定大小的物体，如人物，能移动到某处而不在途中碰撞到任何东西。

Notes: For colliders that overlap the capsule at the start of the sweep, the output direction is set opposite to the direction of the sweep, distance is set to zero as well as zero vector gets returned in the position field of the RaycastHit structure. You might want to check whether this is the case in your particular query and perform additional queries to refine the result. If you move colliders from scripting or by animation, there needs to be at least one FixedUpdate executed so that the physics library can update it's data structures, before a capsule cast will hit the collider at it's new position.

如果从脚本或动画移动碰撞器，需要有至少一个在FixedUpdate中执行，使得物理库可以更新它的数据结构，在CapsuleCast碰到碰撞器之前是在它的新位置。

JavaScript:

#pragma strict
function Update() {
	var hits: RaycastHit[];
	var charCtrl: CharacterController = GetComponent.<CharacterController>();
	var p1: Vector3 = transform.position + charCtrl.center + Vector3.up * -charCtrl.height * 0.5F;
	var p2: Vector3 = p1 + Vector3.up * charCtrl.height;
	// Cast character controller shape 10 meters forward, to see if it is about to hit anything
	hits = Physics.CapsuleCastAll(p1, p2, charCtrl.radius, transform.forward, 10);
	// to use a transparent Shader
	for (var i: int = 0; i < hits.Length; i++) {
		var hit: RaycastHit = hits[i];
		var rend: Renderer = hit.transform.GetComponent.<Renderer>();
		if (rend) {
			rend.material.shader = Shader.Find("Transparent/Diffuse");
			var tempColor: Color = rend.material.color;
			tempColor.a = 0.3F;
			rend.material.color = tempColor;
		}
	}
