Problem!

[Shazer2]

I'm having 2 really annoying problems today. Firstly I'm trying to access a txt file, that is in a folder within the game package. If I do levels/levelone.txt it says the system cannot find the specified path but if I use the absolute path it has no worries. Code below.

package game;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.util.ArrayList;

import org.newdawn.slick.Color;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.Graphics;
import org.newdawn.slick.Image;
import org.newdawn.slick.Input;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.TrueTypeFont;
import org.newdawn.slick.state.BasicGameState;
import org.newdawn.slick.state.StateBasedGame;

@SuppressWarnings("deprecation")
public class Game extends BasicGameState {

	float startPy = 64;
	float startEx = 100;
	float startEy = 340;
	
	int accTime;
	int score;
	int value = 1;
	int health = 200;
	int sh, sw, sx, sy, hh, hw, hx, hy;
	
	Input input;
	Player player;
	Enemy enemy;
	Paused paused;
	Image wallI, playerI, goalI, enemyI, invisibleWallI, healthI;
	TrueTypeFont font;
	String scoreString, healthString;
	
	// list of blocks
	ArrayList<Block> blocks = new ArrayList<Block>();
	ArrayList<InvisibleBlock> invisblocks = new ArrayList<InvisibleBlock>();
	ArrayList<Goal> goals = new ArrayList<Goal>();
	ArrayList<Goal> removeGoals = new ArrayList<Goal>(); // list of goals to remove each frame
	
	public int getID() {
		return Main.GAME_STATE;
	}

	public void init(GameContainer gc, StateBasedGame sb) throws SlickException {
		wallI = new Image("game/images/w.png");
		goalI = new Image("game/images/g.png");

		}

			InvisibleBlock invisBlock = invisblocks.get(ib);
			invisBlock.draw(g);
		}
		
		player.draw(g);
		enemy.draw(g);
		
		scoreString = "Score: " + score;
		sh = font.getHeight(scoreString);

I am stumped for ideas, so if anyone can help I would really appreciate that.

You probably have a different working directory then you think you have. When running in Eclipse (or probably any other IDE), the working directory of a running application is the location on disk where the code was compiled. You need to change your start-up configuration in the IDE to make the working directory the root of all your data.

e.g. If your images are located at "C:/new/folder/on/disk/game/images/" then you would have to put your working directory to "C:/new/folder/on/disk/"

P.S. Your post says 2 problems, but I only see one.

Clearly, the second problem is that he's stumped for ideas 


... I apologize.
