バッファリングされたイメージを使用してスプライトをレンダリングする

Question

私はバッファリングされたイメージを使用してスプライトシートからスプライトをレンダリングしようとしていますが、イメージを呼び出してもコードが機能しないクラスから？

コード：

package com.game.src.main; 

import java.awt.Canvas; 
import java.awt.Color; 
import java.awt.Dimension; 
import java.awt.Graphics; 
import java.awt.Image; 
import java.awt.event.KeyAdapter; 
import java.awt.event.KeyEvent; 
import java.awt.image.BufferStrategy; 
import java.awt.image.BufferedImage; 
import java.io.File; 
import java.io.IOException; 

import javax.imageio.ImageIO; 
import javax.swing.JFrame; 

public class Game extends Canvas implements Runnable { 

    private BufferedImage spriteSheet = null; 
    boolean sprite = false; 
    private BufferedImage sprite; 

    public void init(){ 
     BufferedImageLoader loader = new BufferedImageLoader(); 
     try{ 

      spriteSheet = loader.loadImage("/astronaut_sprite1.png"); 
     }catch(IOException e){ 
      e.printStackTrace(); 
     } 
} 

    private void render(){ 
     BufferStrategy bs = this.getBufferStrategy(); 
     if(bs == null){ 
      createBufferStrategy(3); 
      return; 

     } 

     if(sprite == true){ 
      g.drawImage(sprite, 0, 0, getWidth(), getHeight(), this); 
      System.out.println("True"); 
     } 

     g.dispose(); 
     bs.show(); 
} 

    public void keyPressed(KeyEvent e){ 
     int key = e.getKeyCode(); 

     if(key == KeyEvent.VK_1){ 
      sprite = true; 
     } 

} 

    public static void main(String args[]){ 
     Game game = new Game(); 

    public BufferedImage getSpriteSheet(){ 
     return spriteSheet; 
    } 



} 

私は（スプライト）を呼んでいるクラスがある：

package com.game.src.main; 

import java.awt.Graphics; 
import java.awt.image.BufferedImage; 

public class sprite{ 

    private double x; 
    private double y; 

    private BufferedImage sprite; 

    public sprite(x, y, Game game){ 

     SpriteSheet ss = new SpriteSheet(game.getSpriteSheet()); 

     sprite = ss.grabImage(3, 3, 32, 32); 
    } 

BufferedImageLoader：

package com.game.src.main; 

import java.awt.image.BufferedImage; 
import java.io.IOException; 

import javax.imageio.ImageIO; 

public class BufferedImageLoader { 

    private BufferedImage image; 

    public BufferedImage loadImage(String path) throws IOException{ 

     image = ImageIO.read(getClass().getResourceAsStream(path)); 
     return image; 

    } 

} 

Answer 1

使用ImageIO.read(new File("/astronaut_sprite1.png"));代わりのspriteSheet = loader.loadImage("/astronaut_sprite1.png");

あなたのフォルダ構造：

-src 
--com 
---m14x 
----game 
-----BufferedImageLoader.java 
-----Game.java 
-----SpriteSheet.java 
-res 
---sprite_sheet.png 

あなたBufferedImageLoaderクラス：

public class BufferedImageLoader { 
     private BufferedImage image; 

     public BufferedImage loadImage(String path) throws IOException{ 
      System.out.println("PATH = " + path); 
      File file = new File(path); 

      if (file.exists()) { 
       // First, make sure the path exists 
System.out.println("File exists!"); 

      } 
      if (file.isDirectory()) { 
       // This will tell you if it is a directory 
System.out.println("File is a directory!"); 

      } 
      if (file.isFile()) { 
       // Similarly, this will tell you if it's a file 
System.out.println("File has a path!"); 

      } 
      System.out.println("Trying to load image:"); 
      image = ImageIO.read(new File(path)); 

      //image = ImageIO.read(getClass().getResource(path)); 

      System.out.println("Image path found. Returning..."); 
      return image; 


     } 

    }
