Question

关于Unity的Vector3的问题

void Update()
{

RaycastHit hit;

if (Input.GetMouseButtonDown (0)) {
Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);

if (Physics.Raycast (ray, out hit)) {
if (hit.collider.gameObject.name == "Plane") {

pointerObj.transform.position = hit.point;

}
else {

Vector3 A =new Vector3(hit.point.x,hit.collider.gameObject.transform.y,hit.point.z);
pointerObj.transform.position=A;
Debug.Log (hit.collider.gameObject.name);
Debug.Log(1111);

}
}
}

为什么
Vector3 A =new Vector3(hit.point.x,hit.collider.gameObject.transform.y,hit.point.z);
pointerObj.transform.position=A;
这报错呢？

Assets/Final IK/NavMeshExtension/Scripts/AgentController.cs(72,110): error CS1061: Type `UnityEngine.Transform' does not contain a definition for `y' and no extension method `y' of type `UnityEngine.Transform' could be found (are you missing a using directive or an assembly reference?)

2.Assets/Final IK/NavMeshExtension/Scripts/AgentController.cs(72,124): error CS1502: The best overloaded method match for `UnityEngine.Vector3.Vector3(float, float, float)' has some invalid arguments

Answer 1

Vector3 A =new Vector3(hit.point.x,hit.collider.gameObject.transform.position.y,hit.point.z);
pointerObj.transform.position=A;

追问

和我的有区别吗

追答

Vector3 A =new Vector3(hit.point.x,hit.collider.gameObject.transform.position.y,hit.point.z);
