试图保持屏幕内的游戏对象左，右unity3d界限 [英] trying to keep a game object within the screen left and right bounds in unity3d

问题描述

我有这样的code波纹管我的游戏对象：

I have this code bellow for my gameobject :

private float screenx;
Vector3 playerPosScreen;
 void Start () {
 screenx=Camera.main.pixelWidth-renderer.bounds.size.x ;
 }

 void update(){
  playerPosScreen = Camera.main.WorldToScreenPoint(transform.position);
  if (playerPosScreen.x >= screenx) {
        //playerPosScreen.x=screenx;
        transform.position=new Vector3 (screenx, transform.position.y,transform.position.z);
    }
    //txt.text = playerPosScreen.x.ToString();
    else if(playerPosScreen.x<=renderer.bounds.size.x){
        transform.position=new Vector3 (renderer.bounds.size.x, transform.position.y,transform.position.z);
    }
 }

我正在开发一个 2D 游戏与拼写相机，我的问题是游戏对象是继续走下去出来的画面，我在这里丢失的东西吗？

I'm developing a 2D game with an orthographic camera,my problem is the gameobject is keep on going out of screen , am i missing something here ?

推荐答案

经过一番研究，我发现了一个解决方案，希望优秀的工作与我：

After some research i found a solution wish worked excellent with me :

Vector3 playerPosScreen;
Vector3 wrld;
float half_szX;
float half_szY;
void Start () {
    wrld = Camera.main.ScreenToWorldPoint(new Vector3(Screen.width, 0.0f, 0.0f));
    half_szX = renderer.bounds.size.x / 2;
    half_szY = renderer.bounds.size.y /2 ;
}
void Update () {
    playerPosScreen = transform.position;
 if (playerPosScreen.x >=(wrld.x-half_szX) ) {
        playerPosScreen.x=wrld.x-half_szX;
        transform.position=playerPosScreen;
    }
    if(playerPosScreen.x<=-(wrld.x-half_szX)){
        playerPosScreen.x=-(wrld.x-half_szX);
        transform.position=playerPosScreen;
    }
}
