Swing/AWT/SWT :: BorderLayout - Adding Multiple Video Game Oriented Objects Such As Sprites To JFrame?

May 24, 2014

I decided to write a small Java program to experiment around with BorderLayout, because I'm developing a Java game and I need to have 2 objects placed in a single JFrame at the same time, and everyone I asked said I need BorderLayout to do that.Before you answer: Also, is using BorderLayout the best option for adding multiple video game oriented objects such a sprites to a JFrame?

So the Java program I wrote is supposed to place a JButton on the JFrame and ALSO place a graphic component (a rectangle in this case). The problem is, only the button shows up, as can be seen in the image link below: URL....

Here is the code:

**main.java** --> The main method class + JFrame/JPanel/JButton constructor
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class main {

[code]....

Swing/AWT/SWT :: Adding ContentPane To JFrame

Apr 18, 2014

The program loads, but nothing shows. I did some research and saw that I needed to set the JFrame to visible at the bottom of the frame section. I made the change, but it still does not show anything. Do I need to add everything that I added to the content pane to the frame? From my understanding you add elements to the panel, the panel to the contentPane, then the pane to the frame...

/*
* Filename: UserInformation.java
*/
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;

Drawing Multiple Objects Swing

Jun 30, 2014

I have to do an assigment using Swing, where I have to make a Board(extends JPanel) and add multiple instances of moving elements to it, with following requirements:

By adding a new object to the Board, the others must not slow down. Also the user interface must not be blocked by the moving objects. So, the movement of the objects must be handled in a separate thread.

and

The application must support adding lots of objects, so it is not okay if every object has its own thread, as this would take too many resources. Design the application in such a way that it uses a constant number of threads, meaning that the number of threads does not grow when adding more objects.

The question is:

How to do this thing with constant number of threads?

Video Game - Collision Detection Class?

Apr 30, 2014

I use eclipse as my IDE. I have decided to make my own video game and somebody had sent me a class that could be used for collision detection. The problem with the collision detection class was that it made a box around an object and if something else had touched the object, the collision detection would work. My problem with this class is what happens when i want to use circles? I cant have a box drawn around it. Then it wouldn't work as i would want. Is there a pixel perfect collision detection class out there I can use? It'll be useful in my journey to become successful in computer science! By the way this is in the java language.

Swing/AWT/SWT :: Inserting A Video Into Graphics?

Feb 12, 2014

So I'm doing a project for my CS class where we have to create a snowman doing something. My picture is of Vince Young in the 2005 Rose Bowl. I'm trying to make the actual video clip from Youtube (do I need to download it? If so I can do that) appear on the scoreboard. As of right now, this is my background file:

import java.awt.*;
import java.awt.event.*;
import java.awt.Font.*;
class snowBackground {
public static void drawField(Graphics g, Color field) {
Color sky = new Color(95,166,243);

[Code]...

and this is the Driver file (not sure if this is necessary):

import java.awt.*;
import java.awt.event.*;
import java.awt.Font.*;
public class SnowDriverWSB {
public static void main(String args[]) {
GfxApp gfx = new GfxApp();
gfx.setSize(1000,650);

[Code]...

There are 3 other files that make the actual Snowmen. To do this, I need VERY basic steps, as I'm extremely confused and new to Java. Also, would I need to download the mp3 sound file seperately and play that, or will inserting the video do both?

Stopping Enemy Sprites From Overlapping

Oct 1, 2014

I am currently in the process of making a game in java. it's going fairly well, however, one problem that i am having is that i cant seem to get my enemy sprites not stack up onto one another. What i want to happen is if two enemy sprites come in contact with one another i want them to touch but not to overlap. However, i cant seem to get this to work.

This is the enemy class:

import java.awt.Graphics;
import java.awt.Image;
import java.awt.Rectangle;
import java.util.ArrayList;
import javax.swing.ImageIcon;
public class Enemy extends Base {
int x;

BorderLayout - How To Decrease The Height Of CENTER Position

May 5, 2014

Normally, the height of the CENTER component (or position) is greater than that of the NORTH and SOUTH components in a BorderLayout.

Is it possible to increase the size of the SOUTH component and decrease the size of the CENTER position because the jcomponents I want to add in the SOUTH component are bigger? or shall I have to change the layout and use some other layout?

Adding Objects To ArrayList

Oct 17, 2014

I've two classes: Student and ArrayListExamples (which has my main method in it).

The student class acts pretty simply at the moment with a constructor that takes a name, surname and ID number. I've tested it and it seems to be working. My issue is with adding an object to an array list, here is my effort:

public class ArrayListExamples {
private static int MAX_SIZE = 50;
static Scanner sc = new Scanner(System.in);
public static void main(String[] args) {
ArrayList<Student> students = new ArrayList();
 
[code]....

I know the last loop to add the student objects is wrong.I'm calling the student ArrayList add method with a student object whose constructor requires two strings and an integer. Why isn't this allowed?

Adding New Object To The End Of Array Of Objects

Feb 8, 2015

I am trying to build a method that takes an array of object and adds a new object of that type to the end of it . ONLY ALLOWED TO USE ARRAY , NO ARRAYLISTS VECTORS ECT . i realize that if the array is full you can use the java copy array method to make a new array and double its size until a certain point . The MAX AMOUNT OF OBJECTS is a constant that is 100 but for some reason even when executing my code i keep getting null pointer exceptions or index out of bounds errors , i have written this method many times now with out any success.

My question is how do I write a method that adds an object to the end of an array and if there are no spots left copies the current array into a new array and extend the size

private Animal [] objects;
final int MAX_ANIMALS = 100;
public AnimalObject()
{
objects = new AnimalObject[MAX_ANIMALS];
}
public AnimalObject(Animal[]a)

How To Move Multiple Objects At Once

Oct 8, 2014

I am new to Java programming and i am using BLUEJ to create some basic objects etc.

I have 3 circle objects (individual) and i am wanting to use "slowMoveHorizontal" method to move these 3 objects about 50px to the right.

So far, everything works BUT the issue is that they do NOT move together simultaneously. They move on a ONE BY ONE basis.

Adding Items To The Game

Jan 4, 2015

I made my items class and I am storing my item as a String array to list them all and what I want to be able to do is type pickup, have the game read my location and display the items that are avaible to pickup at current location then type the item and store it in my playerInventory. Then, have it check the slot if it is doesn't equal null go to next.

Use a boolean value of 0 = false and 1 = true. then, have it check if the inv array = 1 or 0. if 1 go to next inv. If all are full then, ask player if they would like to replace an item. Use a 2d array for storage for slots and true or false value.

Here is my code

Player.java
package com.PenguinGaming;
import java.util.Random;
import java.util.Scanner;
public class Player {
public void User(){
Commands commands = new Commands();
Map map = new Map();

ArrayList Only Adding 1 Item When There Are Multiple Items

Oct 25, 2014

I managed to retrieve data, and set data in my own ways in which I like. But my problem is, if the file does not contain anything (fully empty), when I try to use my

set("", "");
method, it only sets the last one that is called.

Example:

set("section1", "section1Item");
set("section2", "section2Item");
set("section3", "section3Item");

Only section3 would get set, and not the others.

Otherwise, if the file contained a section already, then each section (section1, section2, section3) would get set.

Here's how I set the data to the file:

public static void set(String section, String data) {
files.openFileWriter();
files.file.delete();
reCreateFile();
String beforeItem = section + ":" + files.dataList.get(section);
if(files.hasReadData) {

[Code] ....

And here is how a retrieve the data and set them to my arraylist/hashmap:

public void getData() {
String line = null;
openFileReader();
StringBuffer sb = new StringBuffer();
