Cardlayout Format - Change Main Menu Screen Into Game Screen On Button Click
Mar 16, 2015I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
Here is the code from my CardLayout:
import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JButton;
[Code] ....
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CheckerBoard extends JPanel implements ActionListener, MouseListener {
// Main routine that opens an Applet that shows a CheckerBoard
public static void main(String[] args) {
new CLayout();
[Code] ....
Once again kept to a minimal.
Error While Moving The Tiles In Frame
Jan 17, 2014I was following a tutorial on how to make a game when i suddenly got an error concerning moving tiles. i get this error when i tried to use a and d to move:
Exception in thread "Display" java.lang.ArrayIndexOutOfBoundsException: 48600

I do not get the error while using w or s but the tiles are still not moving when pressing them.
I have three classes at work here.

2D Game - How To Create A Library Of Tiles
Apr 8, 2014So I'd like to make like a library of tiles, and it isn't too big, which I could just call using a method, and I would specificy what information I need to get, and it would return that information.
For example, a small section of the tiles library is grass_tile, I call this library and specify what I need, and in this case let's say I need the width, or can the character enter it from north? or can the character just stand on it? So it's like a library or array, with sections of it being named by tiles, and by mentioning these tiles I can information about them.
gTile("grass","walkon") will return true, first because I specifiy grass, and yes the character can walk on grass, so it returns a boolean value of true.
gTile("stone","width") will return 16, first because I specify stone, and the stone's png image size is 16.
What I'm asking is not for how to work out if the character can walk on the tile, or read the width of a tile, but can I create like a library from which I can obtain information by giving the name of the tile, and then telling it what info I need.
If up key pressed && gTile((yTILE + 1).name(),"walkon") == true then moveChar("up")

LibGdx / Box2D - How To Group Tiles Into One Larger Polygon
Jan 19, 2015I am making a tile based top-down 2D RPG and am using Box2D for the physics. Since my game is tile-based, there are many tiles on each map that cannot be moved through. This results in many small individual Box2D bodies. This is obviously very inefficient and makes the game lag. Therefore I figured that combining the individual tiles' bodies into larger complex groups would be better.
The way I thought of doing it is to, first, group together tiles into groups of tiles that all share 2 vertices with at least one other tile in the group. Then, for each group I do the following. First I get all of the uncommon vertices (these should be the ones on the outside of the polygon). Then I connect all of those vertices and then remove all of the overlapping lines. This should result in only lines on the outside of the polygon. Then I sort the lines so that the first line in the sorted array shares its end point with the second line's start point, etc. Then I remove the doubled vertices and using those remaining vertices (I called them the "true vertices") I create the polygon. I know that Box2D only supports convex polygons, but with Box2DSeparator I should be able to do this, but I first want this method to actually work.
/**
* Attempts to combine the given blocks into larger bodies to improve performance.
* @param bs The created wall blocks.
* @param w The world. Used for body creation.
*/
private void makeLargeBodies(Block[][] bs, World w) {
Array<Tile> tiles = new Array<Tile>();
for(int i = 0; i < bs.length; i++) {
[Code] .....
However, this is where the first problem arises. This method is extremely slow for large maps (like 200x200 tiles). I have worked at this for very long and right now my head can't figure out how to make the loop more efficient...
Now for the next part. After that I attempt to create the bodies for the TileGroups:
//create all the groups' bodies
size = groups.size;
System.out.println(size + " groups");
for(int i = 0; i < size; i++) {
TileGroup g = groups.get(i);
System.out.println("Starting group " + i + ".");
long timeCheck = TimeUtils.millis();
g.createBody(w);
System.out.println("Group 0 took " + (TimeUtils.millis() - timeCheck) + " millis");
}
*Note that the printing is for debugging purposes*...
This method is probably not a problem; it is what is inside createBody(World) that is the issue...
public void createBody(World w) {
Array<Vector2> allVertices = new Array<Vector2>();
Array<Vector2> uncommonVertices = new Array<Vector2>();
System.out.print("Starting search for uncommon vertices. ");
long timeCheck = TimeUtils.millis();
[Code] .....
Most of the code is self-explanatory (with comments). My current issue is where I connect the uncommon vertices (see the printed statements). This method does not actually finish (I have let it run for several minutes and it does not complete). This is likely due to a large number of vertices (often around 3000 in a 60x60 map), but I cannot figure out how to make the loop more efficient... Because of this early failure I don't know if the rest of the method works, both physically and in theory.
All relevant classes (Tile, TileGroup, Line) are below:
private class Tile {
private Vector2[] vertices;
private TileGroup group;
public Tile(int x, int y) {
vertices = new Vector2[4];

Collision Detection Using Rectangles - Player Sometimes Passes Through The Tiles
May 19, 2014I 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.
private void movement(){
left=bindObject.getLeft();
right=bindObject.getRight();
up=bindObject.getUp();
down=bindObject.getDown();
bindObject.setColliding(colliding);
[Code] .....
Where bindObject is a class which contains key bindings of following keys:-
left arrow key (when pressed) , left arrow key (when released),
right arrow key (when pressed), right arrow key (when released),
up arrow key (when pressed), up arrow key (when released),
down arrow key (when pressed), down arrow key (when released)
Calculate Possible Tiles Clicked Unit Can Be Moved On And Display It To Player
May 15, 2014Alright, 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).
[ ][ ][ ][ ][x][ ][ ][ ][ ]
[ ][ ][ ][x][x][x][ ][ ][ ]
[ ][ ][x][x][o][x][x][ ][ ]
[ ][ ][ ][x][x][x][][ ][ ]
[ ][ ][ ][ ][x][ ][ ][ ][ ]
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;

JSF :: How To Force Refresh Screen
Oct 9, 2014in my JSF2 app I have screens composed with :
- Header
- Body
In the header I have a combo list. At each change in value in the combo list I have an Ajax request that updates the data in the Body. So far everything is working properly. Now the home screen's structure should be change when the value of combo list change. To do this I have :
- 1 ManagedBean HomeBean that manage the home
- 1 ManagedBean HeaderBean that manage the header
- 2 object HomeScreen1.java and HomeScreen2.java that allows me to valued data from each screen
- 2 services HomeScreen1Loader.java and HomeScreen2Loader.java that manage loading of each type of screen
- 1 template home.xhtml
- 2 fichier home1.xhtml et home2.xhtml
When I log in to the application, I get the good page corresponding (Element type 1 => home page 1). But when I select a type 2 item, the actionListener methode is execute, ManagedBean's data was updated (for type 2 screen) , but the page does not updated. What do you do ?
HeaderBean.java :
package com.omb.view;
import java.io.Serializable;
import java.util.List;
import javax.faces.event.ValueChangeEvent;
import javax.faces.model.SelectItem;

Adding Selector On The Screen
Jan 30, 2014I was working on adding a selector on the screen. Searching for code, I found something that some created better than I ever could. I'm trying to integrate it into my code.
I have a program that is pretty MVC.
I'm in my controller class and I'm calling this code:
java - Drawing a bounding rectangle to select what area to record - Stack Overflow
I've changed it to a runnable and called a wait after I called this class, but it still continues on to the next line.
I'm thinking I'll have to either create a super controller (one that manages two controllers and have a multiple set of views and models) because I'll have multiple views or I'll have to figure out how to wait for it to finish as a thread. As mentioned above, wait() doesn't work.
This is the code in my controller after I changed it back from a Runnable:
SelectionRectangle m_rect = new SelectionRectangle();
//Thread m_thread = new Thread(m_rect);
//m_thread.start();
TopLeft = m_rect.getTopLeft();
BottomRight = m_rect.getBottomRight();
C_view.setText(TopLeft.toString());
Disabling All Screen Buttons
Apr 29, 2014I'm having an issue with a swing application I'm working on. Java version is 4 (I know...). I have a main screen panel with multiple sub-panels (rows). Each of these row panels contains an additional 2 sub-panels. One of these 2 sub-panels contains buttons. When 1 button is pressed, I want to disable all of the buttons on-screen (or any other way of blocking user input) until a background event finishes. The row panels do not know about each other.
The first thing I have tried doing is, when a button is pressed, getting the parent. Using the parent I then iterate through its components, and so on until I'm iterating through the buttons. For each button, I am doing a .setEnabled(false); However, this does not work, why. I've also tried wrapping this process in SwingUtilities.invokeLater() out of desperation, but that didn't work either.
What would be the cleanest way to disable all buttons? Or block all user input? I've also tried adding an opaque dialog which hasn't worked. Last resort would be maintaining some sort of button list, but I'd rather not.

Swing/AWT/SWT :: Screen Resolution / Size
Sep 29, 2014I have created a java gui on Windows 7 with Eclipse EE, using a screen resolution of 1366 x 768. I used groups with specified boundaries. For example:
final Group g5_script_data = new Group(shell, SWT.BORDER_SOLID);
g5_script_data.setText("Current DB");
g5_script_data.setBounds(0, 0, 680, 380);
g5_script_data.setBackground(green);
The groups cover the whole screen.
However my colleague with a smaller resolution looses the far right of the screen.
As this is a proto-type and I'm new to Java I don't want to rework everything or convert it to say a grid layout until the proto-type is accepted and I can start from scratch with a real detailed design. It already has 6500 lines of source.
Just wondered what is my quickest/easiest way to get my app to display on a slightly smaller resolution. For sure it will not be anything silly. Something like 1280 x 768 to 1366 x 768 would do.

for(int b = 0; b < GamePanel.enemy_amount; b++){
GamePanel.enemy.add(new Enemy((int)(Math.random() * 4000),(int)(Math.random() * 200)));

Scaling Text According To Screen Size
Jul 4, 2014What I am creating is a clock. That goes round n round using "getcalendar". It's realtime, but the clock has a constant resolution of 800x800. I have carefully placed numbers from 1-12 on the clock using that resolution placing them pixel by pixel. Now if I resize the window, the clock resizes but the text, it fades away out of the screen because the resolution is too small.
This is how I draw them.
g2.drawString(six, 380, 750);
g2.drawString(twelve, 375, 70);
g2.drawString(nine, 30, 415);
g2.drawString(three, 725, 415);
g2.drawString(one, 570, 120);
g2.drawString(two, 690, 250);
g2.drawString(four, 685, 575);
g2.drawString(five, 570, 700);
g2.drawString(seven, 200, 710);
g2.drawString(eight, 80, 585);
g2.drawString(ten, 80, 235);
g2.drawString(eleven, 205, 115);
I understand why this is happening, obviously because the strings are in a certain place just can't understand how do I make them scaleable? Is there an universal formula? Or do I have to draw every string relevant to some mathematical equation regarding to the screen size.
For example : g2.drawString(twelve, diameter / 2, screenheight / 3);

How To Position 8 Objects Across Middle Of Screen

I would like to position the 8 flowers in the center of the screen but can't seem to get the right formula to do so. Here is what I have so far to draw the flower, which is simply a GOval nothing complex:
Java Code:
box.flowers=8;

box.drawFlowers(xpos1, 400);
