So I have a player an enemy and enemy bounds the enemy can go. I need to have the enemy track my position and when I go into the position (I am using a collision method for this) the enemy comes over at a speed of 1. My problem is the enemy jumps to me and then follows at speed of 2 (2 is the player speed). The code is wrong this is why it is jumping and I have my other problems. so my question is what is a good solution for this? I am trying to make a method to track playerposition() so what I am thinking I could do is find x, y of player then store those into an array and return the array to Enemy so he tracks.
player.java
public class Player{
int x = 100; // Location of player
int y = 200; // location of player
int xa = 0; // Representation of where the player goes
int ya = 0; // Representation of where the player goes
private int speed = 2;
[Code] .....
Please note this is not the entire code I have cut some things out that did not need to be there. Also, the code is just to get an idea of what I was thinking of doing. The ideas that are came up with are not meant to be a reflection of what I already have but, what I could add or replace.
I am trying to design a monopoly board game with a class and a main program. I can not make the method to keep track of the player's position after every roll. After every roll it prints "Previous position: 0".The player should also not go over 14th spot because the board is just 15 including 0. That is what I have (just the particular method and the part from the main program which call it).
public int getpospl1() { System.out.println( getplayer1name() + " Rolls " + "Dice 1: " + getrolld1() + "" + "Dice 2: " + getrolld2() + "" ); int spot1 = 14; //The end spot int start = 0; int previousPosition = start;
Its a basic program that is played by 2 people. Player one is suppose to type a number and the second player is suppose to guess the number. However after I test it out, and if I guess too low or too high I get stuck in "Your guess is too low, try again." infinite loop, what is wrong.
import java.io.*; class GuessingGame { public static void main (String[] args) throws IOException { BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in)); String firstPlayer, secondPlayer; int firstInput, secondInput; int guessCount = 0;

I am trying to place the buttons on the bottom. I tried a few different things but the grid layout keeps grabbing it and making them a part of the grid at the button.
Also, the e.getX()/Y() methods in my mouse listeners always spit out the position of the mouse relative to window instead of the entire screen. Is there a way to flip that or at least a way to track the movement of my window on my screen? Another acceptable fix for me would be to have my Robot object's mouseMouse(x,y) method move my mouse to a position (x,y) relative to the window instead of the entire screen.

1: 3D space. How do i define the space where i will make my world? Is there a certain point that i will define as 0,0,0 or is there some other way.
2: Camera positioning. When i have the 3D space, how to i make it so that the camera will show that what i want it to show. Lets say il define its lokatios 30,50,100 and direction is NW, then how to i make it so that is see the SW direction from the point 30,50,100?
I've been noticing some of my programs have been a little buggy recently, and think it's down to confusion over doubles and positioning. Lets say I have a label called banner that I want to scroll across the screen. Now I need to know the label's width in order to position it, but the width depends on the amount of text, so i use this code:
double bannerWidth = banner.getWidth();
Which forces me into using a double if I want to be accurate.
But the problem is that I'm trying to use a condition that compares the label's horizontal position (currentX) to the left edge of the screen (LEFT_EDGE), minus the width of the label (bannerWidth). In other words when the label is off the screen, it should go back to its starting position.
I assume that means that any variables I use to track the label's position (in this case currentX), or constants that I use to check equality (LEFT_EDGE), have to be doubles as well?
My difficulty is that I iterate currentX. But currentX--; won't work because doubles don't iterate as I'd expect.
So casting becomes an option..... but if I cast to an integer I effectively lose width on the label. And that is magnified each loop, resulting in the label's starting position moving further and further to the left.
I have written a drum machine using Java. Into said drum machine I list all 47 available MIDI drums. The instrument list is placed into a JPanel, along with a gridArray of checkboxes. The JPanel is then in turn added to a scrollpane. I have listed the MIDI drums in order of 'ground-up'. For example, the bass drum is generally at the bottom of most drum kits, so it is at the bottom of my MIDI drums list. Next up would be the snare, followed by the cymbals, and then by all the specialty percussives. Since most beats are started from the 'ground-up', laying to foundation, so to speak, I want the scroll bar of the scrollpane which houses the JPanel, which in turn houses the instrument list and the beat checkboxes, to be positioned, upon opening, at the bottom of the scroll pane. Nothing I have tried works. It always positions the slider somewhere in the middle of the scroll track. Below is a listing of just the buildGUI portion of the code, all the MIDI functionality has been removed to keep the size of the post to this forum down.
I am using the Netbeans IDE for Java creations. What are the steps of creating a media player using Java thru Netbeans as i don't understand most of the jargon and the forms,classes,etc.I don't want to use JavaFx but plain Java Application.I am coming from a Delphi pascal background.
I am trying to create an MP3 player with a totally customized look and feel to it. I know how to do this with .net, but I must be missing something in Java.
I want to be able to NOT have to present the user with the default mediaPlayer.getControlPanelComponent() in order to control the media player. I want to be able to code it to when the user clicks on my "Play" button, I can tell the player to play the song, and so on.
I am currently building a java music player and need getting the volume control to work. I want to be able to set the computers volume directly using an integer. I've created a slider and put the value into an integer. The part that I am having trouble with is getting the volume to work.
I'm trying to make a canteen class that holds water. It holds two quarts of water and two quarts is 100%.
public double maxVolume; public int percentFull;
Right now the Canteen is empty.
public void Canteen() { percentFull=0; maxVolume=0; }
And right now I'm trying to make a constructor that specifies the amount of liquid the canteen can hold and specifies the percent full.
public Canteen(double maxVolume, int percentFull) { }
Should I make this second Canteen an integer, a double, or something else? Also, how do I make sure the Canteen never reaches higher than 100%. I'm also curious how I can keep maxVolume and percentFull connected so the % of water is consistent with the number of quarts(2) the Canteen can hold.
I have two JFrames: frame1 and frame2. frame2 currently has focus, and I want to determine which component of frame1 would have focus if I were to switch focus to frame1, hopefully without actually temporarily changing focus.
Is it the KeyboardFocusManager who keeps track of which element in each frame has focus? Or does each container itself keep track? How does Java figure out which element in a frame gets focus when I switch to that window?
I wrote a single player blackjack code and i want to play this game with multiplayers, which steps should i take to do this
package blackjack; import java.util.Random; import java.util.Scanner; public class Blackjack { public static void main(String[] args) { Random kagit=new Random ();
I have already tried every possible way for removing this bug but all failed. The problem is that sometimes my player passes through the map tiles, i mean, the algorithm is like -- if not colliding, move in required direction; else if colliding, move in opposite direction. But sometimes the second condition fails i dont understand why.
I am creating a hangman code. So the game i am creating is 2 player, first player enters the word and second player guesses. i made the code but i don't know how to restrict the first player from adding random characters into the secret word because for my project the word can only contain letters. so i need making the code so the player 1 can only enter letters.
My code is below:
/** * Auto Generated Java Class. */ import java.util.Scanner; public class Hangman { public static void main(String[] args) { Scanner input= new Scanner(System.in); String player1,player2; int wrongguessamount = 0; //keeps the count of the amount of wrong guesses int correctguessamount = 0; //keeps count of the amount of correct guesses int maxincorrect=6;//makes sure the user cant guess more than 6 times
Which is the best way to keep track of the number of the objects I've created?Is is a good practice to have a static variable, which will be incremented everytime I call a contructor?
The code I have below asks the user how many times you want to roll the dice. It rolls dice 1 and dice 2 randomly and gives the total. Now, I'm trying to keep track of the result of each roll using an array that is indexed by the sum of the roll of the two dice. Then I want to output my result in a table that shows each value (from 2 - 12)) and the number of times that value was rolled. I would like to do this preferably with the JTextArea class, but it doesn't have to be. I keep getting errors.The code below works for the dice rolling in the 1st paragraph. I took out all the bad code I was trying to use for the 2nd paragraph.
package Part2pack; import java.util.Random; import javax.swing.JOptionPane; class Dice{ public static void main (String args[]) { String input = " "; int count = 0,dice1,dice2;
Basically we have to create a calculator that it will have to keep track of the current value, and do the functions that the calculator uses.
But I have it working for the most part, but the current value does not keep...
The double " currentValue " Must stay private.
import java.util.*; public class MemoryCaluclator { private double currentValue; public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); int answer = 0;
So I am trying to create a Multi-Player game in java, and I have a Game server and a Client. They normally connect with either but I would like to add a login server so that there can be an option to go to a different world then just the main one. It will have the same map and data but will be separate from the Players that are on world one per say. Now if you are on world two I would like it to have the option for you to be able to Private message players that are on World one. That is where the login server comes in to play.
I am still new at Java and would like to be able to understand Packets and how to handle them more clearly. So far I have gotten the basis of the login server connected to the server and the client connects to the server via the login server. But I am getting a bunch of "unhandled packets" and I would like to know how to handle them. Here are some bits of the code.
Alright, so I'm having problems with lines 11 - 55. I'm trying to calculate the possible tiles the clicked unit can be moved on and display it to the player.
The field is a 9 (columns) by 5 (rows) grid. A unit with can move tiles horizontally or vertically based on its movement.
Example: (unit = o; possible tiles = x) (assuming movement of 2).
I tried to calculate movement by finding out what column the unit is in, subtracting the column it wants to go to, multiplying the difference by *-1 if the difference is less than 0. Then, doing the same with rows and adding the difference of columns to the difference of rows and comparing it to the unit's movement. Unfortunately, with my code, it seems to move in any directions.
@Override public void mouseClicked(MouseEvent e) { if (Main.cards.size() > 0) { mainloop: for (int i = 0; i < Main.cards.size(); i++) { Card c = (Card) Main.cards.get(i); int startingColumn = 0;
How to start and structure my program because i am fairly new to the program but want to try to make a game. My idea of the game is it generates random numbers between 1-100 for two people and the program compares the two random numbers and declares the player with the higher value the winner like the card game war. Then it would give you an option to try again.
