統一調試日誌全浮

Question

我糊塗了，這是我的創造，並記錄浮動升C腳本：

using UnityEngine; 
using System.Collections; 

public class guicontrol : MonoBehaviour { 
    void CalculatePosition(string ObjectName) { 
     GameObject theobject = GameObject.Find (ObjectName); 
     int selectedwidth = 1366; 
     int selectedheight = 768; 
     int screenwidth = Screen.width; 
     int screenheight = Screen.height; 
     float coordinatey = theobject.transform.localPosition.y; 
     float coordinatex = theobject.transform.localPosition.x; 
     float coordinatez = theobject.transform.localPosition.z; 
     Debug.Log ("work at current stats : " + screenwidth + " " + screenheight); 
     if (screenwidth != selectedwidth || screenheight != selectedheight) { 

      float coordinateytomove = (screenheight/selectedheight) * coordinatey; 
      float coordinatextomove = (screenwidth/selectedwidth) * coordinatex; 
      Debug.Log (coordinateytomove + " " + coordinatextomove); 

     } 

    } 
} 

當我在計算器手動計算的話，的coordinatextomove結果是：

-2.99853587116

，但在調試日誌是：

-3 0

-3是coordinateytomove不從目前的變化的座標，但爲什麼如果coordinatextomove改變，其調試記錄0代替-2.99853587116？如果有以前的帖子回答了這個問題，請原諒我，並給我鏈接的帖子:)。

screenheight/selectedheight會給你整數除法，在得到結果後忽略.右邊的任何內容。你需要投兩中的一個作爲浮動你把

float coordinateytomove = ((float)screenheight/selectedheight) * coordinatey; 
float coordinatextomove = ((float)screenwidth/selectedwidth) * coordinatex; 

之前，你也可以只聲明變量float和以後不必做演員。

int selectedwidth = 1366; 
int selectedheight = 768; 
float screenwidth = Screen.width; 
float screenheight = Screen.height;
