Question

您好我正在尝试为刚开始创建的游戏添加纹理，并且我一直在收到错误，我只是想知道是否有人可以提供帮助。错误指向此.java文件，代码如下。包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);

    }
}

}

错误列表是。

Answer 1

JVM无法找到您指定的资源"\textures.textures/floor.png"。

资源路径不应使用"\"，而应使用"/"代替绝对路径。

在java中渲染图像
