Question

我正在使用Raycast制作RTS动态相机，但我造成了这些问题：

 1. Assets/CameraMover.js(11,73): BCE0044: expecting ), found 'hit'.
 2. Assets/CameraMover.js(11,77): BCE0043: Unexpected token: ).

代码如下所示：

var RaycastHit : hit;
if(Physics.Raycast(Transform.position, -Transform.position, out hit)){
    curDistance = Vector3.Distance(Transform.position, hit.point);
}

if(curDistance != cameraDistance){
    var difference = cameraDistance - curDistance;
    Transform.position = Vector3.Lerp(Transform.position, Transform.position + new Vector3(0, difference, 0), Time.deltaTime);
}

Answer 1

您将out hit作为第三个参数传递给Physics.Raycast，但函数签名为：

public static bool Raycast(Vector3 origin, Vector3 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers);

实际上，您需要移除, out hit，或将其更改为表示您想要进行射线测试的最大距离的浮点数。

Answer 2

好吧，我现在就像@Adam Harwood一样，但是当位置稳定时，它会振动。

var hit : RaycastHit;
var curDistance : float;
if (Physics.Raycast(transform.position, -transform.position, hit)){
    curDistance = Vector3.Distance(transform.position, hit.point);
}

if(curDistance != cameraDistance){
    var difference = cameraDistance - curDistance;
    transform.position = Vector3.Lerp(transform.position, transform.position + new Vector3(0,difference,0), Time.deltaTime);
}

Raycast BCE0044发现期待），发现'命中'
