I'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?"
I started a text based game, but I am dissatisfied with the console that PrintF prints to. How can I set up a window and have text output to that window, and have my player type responses in the window?
So, 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.
I 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....
I 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?
So, 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 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;
I'm working on this space invaders game and I've been stuck trying to get the alien spaceships to move down in one group. The way we have to design the game is we have to implement at least these 3 classes. These classes are GameData,GamePanel, and Animator. GameData is all the action figures/models in the game. GamePanel draws all game action figures/ models on the screen. Animator updates periodicaly action figures positions,sizes, colors etc. I can get the aliens to move right but once they hit the end of the canvas I cannot figure out how to get them to move as a group down and then begin moving left. I tried to add alien objects to the GameFigures list and then have the update method in the Alien class be responsible for moving the alien ships, but I couldn't figure out how to make it work. So then I made an alienFigures list in the GameData class and I still cannot figure out what to do. Here is the GameData class
I made a kind of maze game that includes the class keylistener and orients a object, i can't find where the program tracks this object (where its x and y coordinates are). So now my object can move freely through all walls and i want it to bounce back or at least something to happen when the object reaches a wall.
I want to find a way to limit my objects movement and because i cant find where the coordinates or variable for this object is i cannot limit its movement
I'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.

i'm totally new to Java.I'm making a small text based RPG and this is what i've come up for now.
Java Code:
import java.util.Scanner; class Main { public static void main(String args[]){ Scanner input = new Scanner(System.in); Player playerObject = new Player();
[code]....
My thing is that i want the user to enter 'Caucasian' or another race in the console below and i want it to be saved in a variable or something else in the Player Class that i can later use it in texts or something else. My question is how can i do it?
I tried like 'int Mongoloid = 1; int Caucasian = 2;'
And the same with the others, and after that i tried to use them with the Switch Statement but it did not work.
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.
I 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.
I have list of employees in my database and their associated information like employeeId,supervisor and process. I have class named EmployeeDetails having same properties. I am fetching details of all users using below code:
In employeeList, we have list of objects having data of employees. I donot know how to get which object is selected in dropdown and based on that rest of the text fields are populated. Example:
Name ID Supervisor ------------------------------------------------------- Pawan Kumar3033045Vimal Kumar Vimal Kumar3040901Dinesh Hemrajani
If Pawan Kumar is selected from dropdown then '3033045' and 'Vimal Kumar' should get populated.
For an assignment I need to read an input text file and evaluate the triangle based on the data found in the text file which consists of an unknown number of groups of 3 numbers (Each group representing a different triangle). According to the project specifications I need to have a main method and several other methods. I have the main method set-up to receive data correctly but I am confused as to how I would get the values out of the text file and use them in the main method. For example, if I were to call the computePerimeter method in my main method, how would I make sure I get the correct perimeter for the given data?
Here is the code I have so far:
import java.io.*; import java.util.Scanner; public class TriangleEvaluator { public static void main(String[] args) throws FileNotFoundException { Scanner in = new Scanner(new File("triangleData.txt")); double s1; double s2; double s3; while (in.hasNextDouble())
I am making a shopping cart app in JSP and servlets to bring it all together. Finally.
I have a registration servlet (c1), a registration form jsp (c2), a login jsp (c3). c1 checks if a username is in the database or not.
If the username is not there, then register the user and send them to c3. I want c3 to display a "registration successful" message if a user has just registered successfully and is coming from c1. ELSE, take the user back to c2 with a message which tells them to choose a different username or password etc.
How do I implement the logic of showing a message depending on where a user is coming from ? The servlets and jsps are ready and I only need to add this logic for a custom message. Of course, I could make a JSP for Registration Successful and one for Registration Failure. But, that seems to be unnecessary.
I'm creating a text adventure game, but there are some bugs in it that can get annoying such as restarting the program when it shouldn't be, going to the wrong piece of text, etc.
Java Code:
import java.util.Scanner; public class Act_1 { /** * @param args */ public static void main(String[] args) { boolean again = true; do{ int option; Scanner input = new Scanner(System.in);
System.out.println("You are Paul Soares Jr, an expert survivalist who has been caught in the midst of a zombie apocalypse in the land of MineZ. You awaken in a dense forest with a lake nearby. In your backpack you have a wooden sword, a pack of matches, one torch, some snacks and meals, a H.A.M. radio, a full water bottle, and a bandage.");
System.out.println("");//the "" adds a space in the text System.out.println("Do you: "); System.out.println(""); System.out.println("<1> Head inland"); System.out.println("<2> Stick close to the water"); option = input.nextInt();
I have a main class that hold the frame and paints, a class for drawing my game, and an image that is drawn too. I want to count the amount of times I click on this "android" (right now it counts if i click the screen) but the text from the class Game doesn't update.
androidX = Main.width - android.getWidth();
doesn't work. In my head the image should be inside the borders but it isn't. Have I calculated the pixels wrong or am I missing something?
public class Main extends JPanel{ public static final int width = 600; public static final int height = 600; Game game = new Game(); Android android = new Android(); public void paint(Graphics g) { super.paint(g); game.render(g); android.render(g);
I am making a java text adventure and i am trying to add characters to it. I wrote it exactly the same as i wrote the items class (which works fine) but for some reason the character class keeps getting a null pointer exception when it gets to line 140 in the room class
characters.add(c); game class import java.util.ArrayList; import java.util.HashMap; /** * Game class for Free Willy Five: an exciting text based adventure game. *
I have been working on this mouse movement code that detects which direction the mouse moves in hope to use it in a game. The only problem is that I can not figure out how to make it move to the other side of the screen so I could continue turning to the right or left without having to stop. How would I actually get the x and y coordinants of the mouse to change?
PHP Code: if(x == xscreen){ //set x to 0 }else if(x == 0){ //set x to xscreen }else if(y == yscreen){ //set y to 0 }else if(y == 0){ //set y to yscreen } mh_sh_highlight_all('php');
First, I have a figure that moves around the screen. It uses keylisteners and just subtracts or adds pixels. However, I notice the movement is not smooth at all. It is very rigid and laggy movement. How can I make it smoother movement?
Second, you get three lives in the game. The lives are subtracting correctly, but I want the game to say "GAME OVER" on a dialog box. How would I get this to happen? My JFrame and my life int are in separate classes. I know I should use an if statement, saying if lives are at or less than zero, open the box, but how do I open the box?
Third, I want to display the time on the screen. I have a swing timer, but how do I put it on the screen? DrawString is not working for me.
Fourth, I want to set an icon for the game, the code is running, but not doing anything.
I am new to DreamInCode! I was creating a game using OpenGL (and slick for textures).
Using Vector3f, I make coordinates to where my camera is camera'ing (and rotation).
It was working... until I modified something. I only added shaders. When I took the shaders off I think I might of accidentally deleted something. Nonetheless the code looks perfect to me.
On the method "input()" everything runs. No errors are thrown anywhere. I have syso'd the hell outa my code. It shows no signs of breaks. I can, however, move elements I put into my program. I am 100% sure that no other class is breaking my game (soon to be).
What you should look out for: I am not really sure about the glLoadIdentity()'s and glMatrixMode(). I am, knowing a good part of, thinking it could be gluViewPort....
My problem: Can't move my camera even tho it was working before.
I just started to learn Java. In my program, I created a GRect(paddle) and I would like to move it on the x axis whenever the mouse is moved.
import acm.graphics.*; import acm.program.*; import acm.util.*; import java.awt.*; import java.awt.event.*; public class BreakoutClass extends GraphicsProgram { /** Width and height of application window in pixels */ private static final int WIDTH = 400; private static final int HEIGHT = 600;
[code]....
In this case, whenever the paddle reaches the right edge of the screen, it doesn't move off the windows, but it stops moving (even if you move the mouse).
