Tiled Based Map Game In Java
May 10, 2014I'm trying to create a tile based map JPanel but all I get is a white screen. I'm fairly new to the Java Swing and AWT package so I've been watching tutorials on YouTube so learn as much as I can.
I've got three classes: Window.java which includes the Main method, Panel.java which is the JPanel and Tile.java to draw all the images into an array.
Window.java:
import javax.swing.JFrame;
public class Window extends JFrame {
public Window() {
setTitle("Project");
setSize(500, 400);
[Code] .....
I've checked through everything and still cannot find what I'm doing wrong. I did try different codes but I just got errors instead.
How To Do Movement In Text Based Game
Feb 13, 2015I'm relatively new to Java, I'm trying to create a text based game, like those old ones where you type "north" or "east" to move as such, and "look" to inspect the area. My only problem thus far has been trying to figure out just how I should... "structure?" the movement. As in, what's the best overall way to approach this? I've tried making a new method for every area and just passing a variable called "location," but along with passing the inventory and stat arrays, it's just become messy. Or is this a good way to do it? I have a separate method for when the player enters something, but then how will it know which description to give when the player types "look?"

View Replies View RelatedText-based Game Map Creation
Oct 25, 2014So, I've been working on creating a text-based game engine that would create games similar to Achaea. It's been working pretty well so far. I just finished creating a great mapping system, but now I've run into a problem. I have a mapping system, but actually creating a map would prove to be quite a lot of work. Each location that the player can be inside of has a name, description, map symbol, and an array of the things inside of it. How can I make some sort of map creation program or something so that I can create my maps more easily?
I thought perhaps making a constructor that accepts a list of files, the first containing a table of strings for the names, the second containing a table of strings for the descriptions, etc.; but it seems that would be quite tedious and may be more complex than actually just hard-programming maps.

Text Based Game Adding Items
Apr 11, 2014I am trying to make a text based game. the game has been working perfectly setting up the rooms, first couple of commands, and running it. I am now trying to add items to it but every time it try to run the game it returns :
java.lang.NullPointerException
at Room.addItem(Room.java:107)
at Game.createRooms(Game.java:133)
at Game.<init>(Game.java:28)
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
[Code] .....
Here are the classes that matter for this particular situation
import java.util.HashMap;
public class Item
{
private HashMap<String, Item> itemList;
private String name;
private String itemDescription;
[Code] ....
I know that it is the line
itemList.put(item.getItemName(), new Item(item.getItemName(), item.getItemDescription()));
In the game class that is causing the nullpointer exception i just really cant figure out why that keeps happening and how to add the values correctly....
How To Implement Basic Text-based Rpg Game In A Website
Jan 13, 2015I started programming some time ago and i recently finished a game i've been programming in Java just to get used to the code. The game is a simple text-based RPG where almost everything is random except the character movement.
I've been thinking about learning HTML and CSS because i'm really interested in building webpages. I have no one to ask this question so here i am.
Is there a way to implement my game in a webpage?
I imagine a black window exactly like a classic OS terminal where the text is streamed and the user can play the game with keyboard inputs. I made the game with 5 different classes, i used Eclipse and i have my project there. Should i use a service like Github to share works like this one?
Making A Window For Java Text Based Game
Jan 10, 2015So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD).
I want it sort of like this window: This Pic
Text Based RPG Game - Working With Multiple ArrayLists
Feb 22, 2014I have come across an issue with arraylists. I am writing a text based RPG game as something to start with ...
Initially I had a single zone which was all stored in an arraylist and everything was working in regards to the player moving around. The problem I now have is how to add further zones to my game. Ideally I would like an arraylist for each zone, and would use the below to create each arraylist
public static ArrayList<RoomsClass> castleMap = new ArrayList<>();
The problem I now have is how to handle the player moving, initially with a single zone/arraylist I could reference that arraylist directly
public void findRoomCoords(int ID) {
for (int i = 0; i < castleMap.size(); i++) {
if (castleMap.get(i).roomID.equals(ID)) {
PLAYER.setCurrentRoomZone(castleMap.get(i).roomZone);
PLAYER.setCurrentRoomX(castleMap.get(i).roomX);
PLAYER.setCurrentRoomY(castleMap.get(i).roomY);
PLAYER.setCurrentRoomZ(castleMap.get(i).roomZ);
}
}
}
My initial thought was to use a getter/setter to remove the reference of castleMap from my movement code in order to access different arraylists, however this is where things have fallen over, I can't seem to work out how to get the arraylist name to change, depending on the outcome of the setZoneMap() method.
public void setZoneMap() {
switch (PLAYER.getCurrentRoomZone()) {
case 0: {
zoneMap = Castle.castleMap;
break;

Complicated ArrayList Function - Moving Between Fields Which A Player Can Perform Based On Game Rules
May 27, 2014I have been working on this function and i can't get it to work. It's a little bit complicated so let me first explain what this is about:
1. As a little exam in my studies i have to program a halma console game with KI an stuff.
2. Everything is finished and works except for the Move-Calculation.
3. A Move is a Move from Field a to Field b which a player can perform in one round based on the game rules (Careful: We are not using the standard halma rules, we use different ones).
4. Class Move consists of the Starting Cell where the Figure before the Move stands and a target Cell where the figure will stay on at the Move end. It may include an Array of serveral Cells, the stop cells which the figure passes from start -> target since several jumps can be performed in one Move.
Valid Examples for Moves:
a -> b (From Field a to Field b)
d -> f through g,h,i (From Field d to Field f through the Field g,h,i
My Move Calculation where all possible Moves are calculated for a given figure consists of 2 parts. An expand() function which will generate all possible moves (works perfectly) and a jumpFix() function which isn't working properly.
Example:
After expand() I'm getting something like that:
a -> b
b -> c
c -> d
s -> t
This is however not finished, because the first 3 Moves are actually 1 Move. Because the player can Move from a -> d in one turn because those 3 are consecutive Move. The fixed Move would look like that:
a -> d through b,c
jumpFix() is also perfectly working for that situation, however there is one specific situation when it doesn't work. Let's say we have this situation.
a -> b
b -> c
c -> d
b -> e
e -> f
f -> g
s -> t
Then the only valid jumpFix() output would be:
a -> d through b,c
a -> g through b,e,f
s -> t
However i can not get it to work yet. Note: It definitely needs to be iterative, not rekursive else i would get an StackoverflowError.
This is my current Code of jumpFix():
Java Code:
/**
* Takes a look into all calculated moves and finds those which should be seen as one move, but are still considered to be more than one move (several jumps in one move)
*/
public static List<Move> jumpFix(List<Move> moves) {
Set<Move> result = new HashSet<Move>();
Set<Move> remove = new HashSet<Move>();
int lastSize = -1;
// repeat action until no moves could be merged
while (lastSize != remove.size()) {
[Code] ....
How to implement the special case where a Move splits into 2 or more branches and jumpFix() able to handle this case.
Opoly Game - Goal Of The Game Is To Reach Or Exceed Reward Value 1000
Mar 12, 2015Opoly works this way: The board is a circular track of variable length (the user determines the length when the game app runs). There is only one player, who begins the game at position 0.
Thus, if the board length is 20, then the board locations start at position 0 and end at position 19. The player starts with a reward of 100, and the goal of the game is to reach or exceed reward value 1000. When this reward value is reached or exceeded, the game is over. When the game ends, your program should report the number of turns the player has taken, and the final reward amount attained.
In Opoly the game piece advances via a spinner - a device that takes on one of the values 1, 2, 3, 4, 5 at random, with each of the five spin values equally likely.
Although the board is circular, you should draw the state of the board as a single "line", using an 'o' to represent the current player position, and * represent all other positions. Thus if the board size is 10, then this board drawing:
**o******
means that the player is at location 2 on the board.
Here are the other Opoly game rules:
If your board piece lands on a board cell that is evenly divisible by 7, your reward doubles.
If you land on the final board cell, you must go back 3 spaces. Thus if the board size is 20, the last position is position 19, and if you land there, you should go back to position 16. (If the position of the last cell is evenly divisible by 7, no extra points are added, but if the new piece location, 3 places back, IS evenly divisible by 7, then extra points ARE added).
If you make it all the way around the board, you get 100 points. Note that if you land exactly on location 0, you first receive 100 extra points (for making it all the around), and then your score is doubled, since 0 is evenly divisible by 7,
Every tenth move (that is, every tenth spin of the spinner, move numbers 10,20,30,... etc.), reduces the reward by 50 points. This penalty is applied up front, as soon as the 10th or 20th or 30th move is made, even if other actions at that instant also apply. Notice that with this rule it's possible for the reward amount to become negative.
Here is the driver class for the game:
import java.util.*;
public class OpolyDriver{
public static void main(String[] args){
System.out.println("Enter an int > 3 - the size of the board");
Scanner s = new Scanner(System.in);
int boardSize = s.nextInt();
[Code] ....
heres the methods:
REQUIRED CODE STRUCTURE: Your Opoly class must include the following methods (in addition to the Opoly constructor) and must implement the method calls as specified:
playGame - The top-level method that controls the game. No return value, no parameters. Must call drawBoard, displayReport, spinAndMove, isGameOver.
spinAndMove - spins the spinner and then advances the piece according to the rules of the game. No return value, no parameters. Must call spin and move.
spin - generates an integer value from 1 to 5 at random- all equally likely. Returns an integer, no parameters.
move - advances the piece according to the rules of the game. No return value, takes an integer parameter that is a value from 1 to 5.
isGameOver - checks if game termination condition has been met. Returns true if game is over, false otherwise. No parameters.
drawBoard - draws the board using *'s and an o to mark the current board position. Following each board display you should also report the current reward. No return value, no parameters.
displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward. No return value, no parameters.

Run A Method Based On Integer
Jun 1, 2014OK very similar to switches & cases & ifs, but I'm wondering if I can do something like that:
public Method[] method;
method[0] = walk();

method[2] = stop();
for (int i = 0; i < x; i++){
if (i == myNumber) {
run m[i];
return;
}

Console Based Interface Loop
Mar 11, 2015I am implementing a console based interface for an assigment. I've got a DAO interaces and implementations ready and I am stuck on a loop that checks whether to display logged in menu or logged out menu.
public static void main(String[] args) throws SQLException {
Main consoleInterface = new Main();
boolean runningLoop = consoleInterface.isRunning();
boolean loggedOutLoop, loggedInLoop;
while(runningLoop) {
[Code] ....
So when this runs it should show loggedIn() method only and only if the condition is not met. At the start when program runs I set loggedOutLoop = true and loggedInLoop = false. When I handle login I set loggedOut = false and loggedIn = true
What seems to happen is that the else statement doesnt work and the output I've got is only loggedOut() method displayed where I only want loggedIn() to be displayed without loggedOut().
Insertion Sort Based On Two Attributes
Feb 4, 2014public class Employee {
private String firstName;
private String eeid;
}
I want to sort using empoyee firstName.. If two employee names are same, i need to sort based on eeid.. using insertion sort
if (key == "name") {
for (int i = 1; i < list.length; i++) {
Employee t = list[i];
int j;
for (j = i - 1; j >= 0 && t.getLastName().compareTo(list[j].getLastName())<0; j--)
list[j + 1] = list[j];
list[j + 1] = t;
}
}
It will sort using names.. But if two names are same, it wont sort based on eeid.. I want to achieve only using insertion sort..
EX:
vivek 8
broody 2
chari 3
vivek 5
chari 1
output:
broody 2
chari 1
chari 3
vivek 5
vivek 8

DAO Based Application - Replacing Old Textfile
Apr 16, 2014I'm currently trying to build a DAO based application where you use a text file as a data source. It have worked out well until I tried to delete lines from the file.

Text Based RPG - Allow User To Change Their Name

String whatToChange = "name";
String verifyNameChange = "";
boolean changeName = false;
if(whatToChange.equals("name")){
while(!changeName){
[Code] ....
I've been working on a small text-based RPG for fun. This particular part is supposed to allow the user to change their name. Now, the problem is that when they reach the option to change their name, the above code seems to skip the line:
name = scan.nextLine();
It will erase whatever the player previously entered for their name, as well. So it will print out:
Okay, let's change your name. What did you say it was? Alright, so you'll go by . Is that correct? [now allows input for verifyNameChange]
The above code works fine on it's own, but somehow messes up when put into the full program. I don't want to post the whole program, because it's fairly large. But the String name is set and functions fine before this bit of code.
