Swing/AWT/SWT :: 2D Spaceship Game - Image Rotation And Position
Aug 29, 2014
I'm attempting to create a 2D spaceship game from scratch. My problem is that I feel like the way Im rotating images is awkward and just wrong. I believe what I'm doing in the following code is loading an image into a JPanel and rotating the image and moving the JPanel.
The code is unrefined and only partial, but it show how I am manipulating images.
What seems so awkward is that I have to create a new JPanel for every image, I would think there is a better way but I don't know. I have tried to get one image on top of an other with the JPanels to no avail. That said I haven't put much time into trying to get that to work. I want to know if I should continue my attempt with JPanels or to pursue a different method.
I'd like to draw an overlay on an image. The overlay is also an image with a black background and a white foreground. Now the white pixels should be drawn on the image in red. This is possible with the code I posted below. However, the problem arises when rotating the stencil (overlay). I get some interpolation errors from the rotation on the boundaries. I tried to clip them with setClip(), but this turns the background from transparent to white. How to remove those spots? Or maybe a completely other idea of achieving an overlay on the image? I'm aware of the pixelreader and iterating through the stencils pixels and draw the respective pixels as rectangles on a Canvas' graphicContext. However, this was extremely slow, compared to the code I posted below (although it doesn't work with rotations).
I have a class that retrieves an image, and a class that is a game. I want to put my image onto the game to use it as the main figure. As of right now in eclipse, the game class runs, so the game works, but the image doesn't do anything. Need to put the image into the game? Here is my image class:
I see this is an object reference, but what is on the right side? Does not seem like a method, as it would not equal a method nor would the parentheses be on the left. Why are parentheses there? Disregarding the above code, I would like to know how to rotate without Graphics 2d
Also, with G2D you it will not allow for setting x coords
I'm experimenting with AffineTransform, Basically I've created just a simple test GUI to see how the code works and all that. Anyway, there are two buttons which turn an image left and right and a third button with moves the image to the right (East). When you first run the program the image is facing down (South). Now to turn left or right I'm using an Affine Transform and the rotate method. That works fine. The issue is when I move the image to the right, it ignore whatever rotation I previously I made (from turn left and right buttons). Therefore when I click to move the image, it faces down again even if it was facing left or up or right before I moved it. It will always be facing down. How do I get it to keep the rotation and just move? Btw I'm using the setTranslate method to move the image.
Below is my code.
Images.java import java.awt.image.BufferedImage; import java.io.IOException; import java.net.URL; import javax.imageio.ImageIO; public class Images { static BufferedImage Icon, Rover;
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;
I need to make a simple applet, but I'm stuck with something. This is how my applet should look:
And this is how that part looks in my applet:
What I've done until now is create one JPanel which includes two other JPanels.. The first one contains only the JTextArea you can see, and the other one includes the other elements.
I just need to make the JTextArea taller, like in the example, so everything comes into place...
So, I have a program that allows me to dynamically add JTextAreas and then drag them around the screen. The problem is, when I add a new JTextArea, I call revlidate() to update the panel. This causes all of the JTextAreas to reset their positions. How can I prevent this from happening? It is happening on this code:
public void addBox() { drag = new DragListener(); JTextArea textArea2 = new JTextArea("Some text Some other text"); textArea2.setLineWrap(true); textArea2.setWrapStyleWord(true);
Sir, 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.
I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
Okay, gotta be able to move the image when a key is pressed. When I test it, the image moves, but leaves the old image behind.
package Game; import java.awt.Component; import javax.swing.JOptionPane; public class Game { private Grid grid; //holds the grid used to store and display images private int userRow; //keep track of which row the user-controlled image appears in private int msElapsed; //keep track of the total amount of milliseconds that have elapsed since the start of the game
[Code] ....
Here is what I was given on instructions:
Complete the handleKeyPress method. Write the following line of code in the handleKeyPress method to check for a key press:
int key = grid.checkLastKeyPressed();
If the user pressed the up arrow (key == 38), move the user's image up one row (unless the user is already in the top row). Likewise, if the user pressed the down arrow (key == 40), move the user's image down one row (unless the user is already in the bottom row). Either way, make sure to update userRow.
Movement of the image can be accomplished by changing the value of userRow. Study how the initial image is displayed in the game constructor, then
Set the current image location to null
Update userRow to the new location and,
Set the image in the new value of userRow.
You should be able to move the user image up and down, and you should be prevented from moving the image off the screen.
So I have this randomly generated set of tiles that is wrapped in a circle and I'm not really sure how to scroll it around the circle. Basically it's a side-view planet that is in 2D and needs to be wrapped and moving at a controllable rate to give the illusion of planet rotation. What to do to the x and y to make it scroll around. I want every tile except the water tiles to move from left to right and then wrap around the circle. Here's what a planet looks like: [URL] ....
Java Code:
for (int x = 0; x < planet1.length; x++) { for (int y = 0; y < planet1[0].length; y++) { if (planet1[x][y] == 1 || planet1[x][y] == 2) { g.drawImage(water, x * 32, y * 32);
I have a UI widget, like a table view for example, displaying real-time data. This table can be configured - so it has many properties. The way I would like to do so, is to have a small 'configure button', once clicked, would rotate the entire table along its y axis, and display another panel with checkboxes etc... So effectively, the hidden properties panel is revealed by rotation.
We are doing a visualisation tool for point cloud research project. We use 3d sphere to represent each single point and when we have large number of points to display (~40,000), the rotation becomes very lagging.
What we have tried:
set JVM flag -Djavafx.animation.fullspeed=true, this worked a bit, but not significant.set JVM flag -Djavafx.autoproxy.disable=true, this did not work.
set Cache to true and CacheHint to Cache.SPEED, this did not make much difference.create another thread to do the rotation, and sync back after calculation, this did not work neither.
1. The human user of my application asks it to fire up a scanner which scans a paper document. The document is a filled in form. 2. The application then displays the scanned image to the human user.The image is displayed in a JScrollPane since it may be larger than the scroll pane. 3. The human user needs to locate a certain item in the form, for example a social security number, and enter it into a field in a data entry screen.Note that the image and the field appear on the same screen.
Of-course the social security number always appears in the same location in the image. Also the image needs to be the appropriate magnification and resolution to allow the human user to easily read and understand the item he is searching for in the image.
What is the best way to present the scanned image to the user such that he immediately sees the item he requires and can enter it into the data entry field.
I have added the image in the src and bin directories and cross-checked that the name of the image file is correct..Here is the main class
import javax.swing.*; public class apples { public static void main(String args[]) { JFrame frame = new JFrame(); MyDrawPanel wid = new MyDrawPanel(); frame.add(wid); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); frame.setSize(300,300); } }
and here is the class that does the image adding part
import java.awt.*; import javax.swing.*;
public class MyDrawPanel extends JPanel { public void paintComponent(Graphics g) {
Image image = new ImageIcon("b.png").getImage(); g.drawImage(image,20, 20, this); } }
My database contains path of images that I want my jComboBox to diaplay. I have written the following code but it does not work for comboBox but works fine when I display image on jLabel etc. How should I go about this
try { ByteArrayInputStream in = new ByteArrayInputStream( transferWorker.bOutput .toByteArray()); BufferedImage bufferedImage = ImageIO .read(in);
[Code] ....
But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.
I have a GUI with several buttons and I'm using NetBeans GUI Builder to do. At the click of one of these I would like for it to open another frame containing a picture. So I associate a listener (actionPerformed) the button and when clicked it opens actually post the new frame.
In the new frame I waxed a JLabel and then I associate the image of the label. I saw that to do that NetBeans generates this code:
My problem is that the picture is overwritten several times during the execution of the program is not changed yet in the frame. That is, in the new frame is always displayed an old version of the image.
I have an image that is created every time I click on the button (it always has the same name and same path). Basically I have a generic tree on which I perform the operations (add, remove, etc..). When I click on the button I call a method that generates the image of the tree (using Graphviz). So I have one image that changes over the time...
How can I do so that the image is always up to date?
The Code:
package View; import javax.swing.Icon; import javax.swing.ImageIcon; import javax.swing.JLabel; public class AlberoIpotesi extends javax.swing.JFrame {
Any way to resize an ImageIcon when placing it on a Button so that I don't have to physically rezize the image file?? I am writing an Application, not an applet, so the getImage method won't work.
I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.
public class MoveIt extends Applet implements ActionListener { private Image cup; private Panel keypad; public int top = 10; public int left = 10;
[Code] ....
I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.
I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:
