在java中渲染圖像

Question

你好，我想添加一個紋理到遊戲中，我剛剛開始創建，我不斷收到錯誤，我只是想知道是否有人可以提供幫助。 錯誤指向這個.java文件並且代碼如下。 package com.mime.minefront.graphics;

import java.awt.image.BufferedImage; 
import javax.imageio.ImageIO; 

public class Texture { 

public static Render floor = loadBitmap("\textures.textures/floor.png"); 

public static Render loadBitmap(String fileName) { 
    try { 
     BufferedImage image = ImageIO.read(Texture.class.getResource(fileName)); 
     int width = image.getWidth(); 
     int height = image.getHeight(); 
     Render result = new Render(width, height); 
     image.getRGB(0, 0, width, height, result.pixels, 0, width); 
     return result; 
    } catch (Exception e) { 
     System.out.println("CRASH!"); 
     throw new RuntimeException(e); 

    } 
} 

} 

而錯誤列表是。

Answer 1

您指定的資源"\textures.textures/floor.png"找不到JVM定位的資源。

資源路徑不應該使用"\"，而應該使用"/"而不是絕對路徑。
