Question

我在Unity编写游戏。每次用户点击界面时，我都试图在空间中生成一个球体。我可以生成球体，但是球体总是在大约（200,200,0）和（400,400,0）的坐标处，但是球体应该在指针在屏幕上的位置产生。这是我的代码，有人可以帮忙吗？我用C＃编写：

using UnityEngine;
using System.Collections;

public class myscript : MonoBehaviour {

//initialize a circle
public GameObject Node;
public float cooldown = 1;

bool clicker;
float clicktime = 0;

GameObject node; //reference to the prefab

// Use this for initialization
void Start () {
}

//In everyframe you can 
void Update () {
    clicker = Input.GetMouseButtonDown(0); //obtaining the input
    clicktime += Time.deltaTime;

    }

//Check whether you can shoot
void FixedUpdate(){
    if (clicker == true && clicktime >= cooldown) { //if the clicker is clicked and the previos clicking is done
        SpawnCircle(); //spawn a circle
        clicktime = 0; //reset timer
    }
}

void SpawnCircle(){
    //this creates a new game object
    x = Input.mousePosition.x
    y = Input.mousePosition.
    node = GameObject.Instantiate (Node,Input.mousePosition,Quaternion.identity) as GameObject;
    //settings that we initalize our object with
    //node.transform.position = new Vector3(Input.mousePosition.x, Input.mousePosition.y,0);
}

}

您需要计算ScreenToWorld坐标。使用Unity它实际上很容易。
