Where can I find tutorials about how you like have a big image, bigger than the specified screen, for the map of a game, and then you have camera view, the image is being printed on the screen continously as the character moves in different areas depending on what area of the map the character is in?
NOTE!!! I don't want to move objects around, I just want a camera view on a large image!
I am new to java and i want to create an application which detect an image which took from camera and to process it so that it can be verified ..for example number plate of the vehicle ..if i need to extract the numbers from the image ..
View Replies View RelatedI am trying to draw an image unto the screen, however, nothing appears...
Java Code:
private ImageIcon i = new ImageIcon("image.png");
private Image image;
...
image = i.getImage();
...
g.drawImage(image, (int)(x - r), (int)(y - r), null); mh_sh_highlight_all('java');
Am I doing it right? The program gives me no error, it's just that when I try to draw it, I see nothing.
I tried to make a buffered screen image that constantly refreshed an image (a black screen) however it does not seem to be working.
Java Code: import java.awt.Canvas;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;
[code]....
I am writing a piece of software to display an image on the screen using a particular library. The library lets me create an Atlas out of texture file data, to fetch Textures out of the Atlas using the textures' names, and to draw the textures by calling Renderer.draw(texture). It doesn't make a great deal of sense to create more than one of an Atlas or Renderer. I previously designed my code as follows:
public class SystemAssets {
static Atlas atlas;
public static void initializeAtlas(String pathToTextureFiles) {
atlas = new Atlas(pathToTextureFiles);
}
public static Texture getTexture(String textureName) {
return atlas.getTexture(textureName);
}
}
Similarly, I made a TextureRenderer class whose sole purpose is to provide static access to a Renderer. But many people seem to say that opening up a class like this to global access is bad. I cannot think of any better alternative, however. My core update/draw logic currently works something like this:
public class Game extends AbstractGame {
public void init() {
Screen current = new FirstScreen();
TextureRenderer.initialize();
[code]...
Making a Renderer object belong to the Game or Screen class doesn't make much sense to me, as there doesn't seem to really be a 'has-a' relationship between them; it's more of a 'uses-a', so that seems to imply that it would be best to just call Renderer.draw(thing) from outside the class rather than making it a data member. This would make my main code essentially call the various methods in order to get or print some form of data, much like System.out.println(). And of course, making one of the classes a subclass of Renderer makes even less sense. But making data members static for the purpose of global access and using singletons are often cited as 'bad' programming practices. This problem also arises in a lot of other scenarios in my program, ie. when I want to serialize Thing data members like texture filenames; do I put the serializer as a static data member in a class for global access and call it like I would a function, or do I put it in a class? And it seems like the Renderer will have to be initialized at the start of the program, which would take place in the init() method in Game, then be used to draw Textures in the Screen, so it would have to be accessible from both locations.
edit: In case it's suggested to put these in the main class, that's unfortunately going to be difficult without using static variables; the library recommends having the main class creating an Application object, which is essentially a black box that actually does all the work of calling Game's init() and draw() methods (via a Game object passed into its constructor) and looping until the program exits. AbstractGame and Screen are classes supplied by the library, so it doesn't seem like I can easily give Game any data that AbstractGame doesn't specifically ask for.
I am building a room management system in Java (Netbeans) and Ms Access. The jasper report is only showing code (source view) instead of design view.

I have the following problem:I have 4 components in my GUI that goes like this in the CENTER of the BORDERLAYOUT:
1. JLabel
2. JTextArea
3. Jlabel
4. JTextArea
Everytime i make the GUI window bigger, all these elements spread out. How can i get these elements to have a BREAK line (i.e. a break line after 1. Jlabel) so that no matter how i stretch the window, it will stay in-tact and the other elements will follow underneath.
public void paint(Graphics g) {
g.drawImage(Background, bg1.getbX(), bg1.getbY(), this);
for(int i=0;i==400;i+=10){
g.drawImage(block1,fg1.getBlockX(),fg1.getBlockY(),this);
g.drawImage(block2,fg1.getBlockX(),fg1.getBlockY()+10,this);
}
}
This is what im dealing with right now. When i click run i only get the background image showing the other two are not showing on the screen.
I'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.
I finally made the app to draw 10x10 map out of 50x50 pixel blocks.Now I can't imagine how to make a camera and lock it on character. I know how to make a character, but I just want to understand how locking the camera on character would look.

View Replies View RelatedSir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
View Replies View RelatedI stored an image into MySQL database using swings and hibernate but I am struggling to retrieve that image from MySQL database and display same image in the jTable cell and same as on jLabel whatever I retrieve from the database using swings and hibernate .
View Replies View RelatedI have two images. I want to be able to click them and kick off a call to a listener in Java to change a value in the bean. I also want the view to update my dropdown (labeled "menuModel") to either be rendered or not, depending on which image I click. Alternatively, I would be fine with the dropdown simply being disabled and enabled for the same criteria.
So far, the listener kicks off fine, and the value gets updated correctly in the bean. However, the view never gets updated. I have tried this a hundred different ways, but nothing seems to work. If I hit refresh on my browser, the view updates. But I want it to do it automatically.

In some examples I see jsf components inside the tag view, other times dont.
- Is it important to put all jsf components inside "the view" tag?
- What would be the difference not putting them inside this tag?
Is it possible to map URL's with independent view dir structure? If so how?
My goal is to simply point an url to a specific view file:

www.myserver.com/application/admin/
to

A couple solutions I found so far where:
Solution 1
PrettyFaces
I just didn't wanted to use a third party solution. This is my best solution so far.
Solution 2(a JSF solution):
navigation rule entries in the faces-config.xml file.
A bean is required, not a bad thing in above example but not great in combination with static navigation like:<h:commandButton action="index"/>
Solution 3 (another JSF solution)
Resource Library Contracts
This forces me to work in the contracts file.
None of the solutions gave me a clear solution except prettyfaces.
Are there some elegant native JSF solutions ? Something flexible and reusable? Something like a mvc controller i used to use in php applications. In this controller I was able to add a template file in the constructor and an content file in specific function. Custom paths where no problem. I didn't want to use mvc nor the php language in this project.

create an application following the MVC pattern. My frame is composed of a JTable with some JComboBox and classic next/previous buttons to page the table. The table shows data of current accounts of the members of a family. My problem is figuring out how the controller interacts with the view, for example to enable / disable buttons or reset and reload the data in the comboboxes. In the view class all the graphical components are private instance variables. What is the best approach to ensure that the controller can act on them?
I need to create in the view public methods to act on each component like getSelectedItemAccountCombo, getSelectedItemYearsCombo, getSelectedItemMonthCombo, populateAccountCombo (ArrayList <String> list), setNextButton (boolean b) ... and so on (I think that the methods would be many ...) This approach does not convince me because I think that the class is fouled by procedures that should be in the controller class.

I have to write a program that will generate 20 random circles with random radius lengths. If any of these circles intersect with another, the circle must be blue, and if it does not intersect, the color is red. I must also place a button on the JFrame. If this button is pressed, it needs to clear out the JFrame, and generate a new set of 20 circles following the same color rules. I am extremely new to Java Swing and am really stuck. I have everything working except the button. I cannot get a new set of circles to generate.

About creating views,
1. When we have a view and this uses two or three managed beans and not only one, is this ok? is a good design?
2 If we have two views and both of them only share one functionality (they need to display datatable with clients) , for the second view and for the shared functionality, should I in the managed bean for the second view create the same method that gets the clients or reuse the method in the managed bean created for the first view?
So I've been working on a music player in android studio and I've created two java classes. One for Main Start Screen(StartScreen.Java) and one for the main player (player.Java). I have an onClicl event associated with a button as shown below.
public void onclick(View view) {
Intent detailIntent = new Intent(this, main_player.class);
startActivity(detailIntent);
}
The code for the second Java Class is as below. There is nothing in the java class as for now.
package com.example.musicplayer.app;
import android.app.Activity;
import android.os.Bundle;
public class main_player extends Activity {

Where is the actual mistake because the app works fine until i click the button that is suppose to take me to the main player screen?
