Page flipping is used in full screen games which entails drawing an imagine off screen then swap with on screen image after drawing has completed.
Is it possible to write a block of code to actually see this happen? Like use this technique on a window that is in windowed mode. Would it draw an image off somewhere by the desktop or would it have to be on the window?
I'm trying to flip an image horizontally. However because when I flip the images they're offset by a bit, I added "-height" to offset the change in position. Unfortunately, it doesn't seem to be working 100% of the time; some images are adjusted to their correct position but some are not.I'm using this line to flip an image: Java Code: g.drawImage(castle, x, y - height, -width, height, null); mh_sh_highlight_all('java');

I'm using JavaKara (a graphic Java software to learn coding) on my classes at the moment and we're asked to transform something like this:
In the inverse, where you can see clovers there must not be any and where there aren't you must plant them. PLUS YOU MUST SWITCH THE FIGURE HORIZONTALLY.
This is the result i should obtain:
public class InvertiECapovolgi extends JavaKaraProgram {
public void myProgram() {
boolean arrayquadrifogli[][] = new boolean[world.getSizeY()][world.getSizeX()]; //[rows][clumns]-->[Y axis][X axis] in kara
for (int y = 0; y < arrayquadrifogli.length; y++){ // My Ladybug starts to run through the whole grid
[Code] ....
How to switch everything horizontally!
This is my result:
My ultimate question is, how do i have to edit the second loop, and why, to obtain the horizontally reversed result i'm supposed to obtain?

View Replies View RelatedHe said that if you need something that Swing can't provide, like a bar graph, you build it. Now, being used to just writing a method that will open up a JFrame, how you would actually build graphics on your own. How in the world would that work? How would one write their own methods to make a window or to build a graph?

I am attempting to create a n-body simulation using orbital dynamics and Java in school.
I am only in high-school, but I have some programming experience. The logic of this program comes quite easily. My problem is the graphical part, so I was just looking for quick methods to implement graphics.
What I am looking to do, is display objects onto the screen and manipulate their respective x and y coordinates as time pass. I have tried to use BufferedImages and an array of every pixel on the screen, but it quickly becomes extremely hard to draw circles etc. I have also tried the Graphics class and using g.fillOval() etc, but this can also get tedious.
Are there any more efficient methods, libraries etc? And also, how should I use the time variable, a variable that updates everytime the program updates?
I wanted to create a interface with buttons ofshapes and type of transformation where user first select a shape, the shape will appear and user will have to click on the buttons on resize, reflect, rotate or skew to transform to shape.

How to rotate a shape in Swing? The only thing I found was something involving this, but I have not seen something like this before:
Java Code : Graphics2D g2d = (Graphics2D)g; mh_sh_highlight_all('java');
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
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, but how.
import java.awt.*;
import java.awt.event.*;
import java.awt.Font.*;
class snowBackground
{
public static void drawField(Graphics g, Color field)

There are 3 other files that make the actual Snowmen.Also, would I need to download the mp3 sound file seperately and play that, or will inserting the video do both?
I used to think that it is simplly a tool to use to change colors and draw to specific container(ie JFrame, JPanel). However, I've been studying buffering (triple, double, flipping...etc) and how it works for 3 days now, and my confusion has only increased. for instance, why when we need to draw to the buffer(ie BufferStrategy, BufferedImage) we get its own graphics object to draw to it and then we project it to the screen? does the Graphics Object represent the drawing surface (ie the JPanel it self if we're using one to draw custom painting via JPanel#paintComponent(Graphics g)) ? so generally speaking if we are using a JPanel and we say bufferedImage#createGraphics and use that graphics object to draw to, we would not be drawing to the JPanel but to the BufferedImage correct?

I am currently drawing graphics onto a JPanel, by overriding the standard paintComponent method.
Is it possible to call a method to draw some predefined shapes, instead of filling this method with all the stuff I need drawn, and if so, how do I do that?
I'm creating a game called Mouse Trap and I'm having an issue with a graphic drawn using AWT. Basically, when the mouse collides with the cheese, I want the cheese to disappear, or call (cheese[i].hide()). However, the cheese does not appear. hide() works for all other objects that inherit from PFigure, but the cheese will not. It's created a major issue in my game, and basically the only task left to accomplish.I believe my problem lies within Cheese.java, method draw(). For example, if I replace it with an example drawing, this problem goes away!:
public void draw() {
Graphics g = panel.getGraphics();
g.setColor(Color.blue);
g.drawOval(x + width / 4 , y + 1, width / 2, height / 2);
[Code] ....
I have three classes below that most likely involve the problem, feel free to ask if you need the others.PFigure.java (This class cannot be changed as a requirement to my project)
import java.awt.*;
public abstract class PFigure implements Comparable {
protected int x, y; // Current position of the figure
protected int width, height; // Drawn (displayed) this size
protected int priority; // Can use to determine "winner"
protected Panel panel; // Panel the figure lives on

I know there are Java graphics classes, and how to use them to draw images in a window, but how do those classes interact with the screen to create the image? At the very base of it all, what is the code that is passing the computer the data to display on its screen? I'm asking because I've seen several ways to do Graphics/GUIS, a lot of them involve the Graphics class, but what is it inside all of that that that makes it work? Also, is everything else involving graphics (any other graphics libraries people write) pretty much "on top" of the Graphics class or is there something else within it more basic that is being used?

I want to know know to copy a rectangle on my jframe and paste it in another location on the same jframe.
View Replies View RelatedBasically I am making a paddleball game, like i'm sure everyone does in learning Java. I'm supposed to use different classes for each component, i.e. one for the ball, one for the paddle, and one for the display, then finally one as a 'controller' to implement mouselistener and stuff.
However, I can't quite grasp how to implement the paintComponent method. I know I can only have it in one class extended from JPanel, and I have the syntax for creating an object which I understand is something like this:
public void paintComponent(Graphics g){ //this is the rectangle my game will be played on,
super.paintComponent(g); //a gray background to define boundaries for the ball
g.setColor(Color.GRAY);
g.drawRect(0, 0, Frame.getHeight(), Frame.getWidth());
However what I don't understand is, how do I then pass this graphics object to the ball and paddle to let them draw themselves? I found something that described it like this here
class GamePanel extends JPanel {
Entity e=new Entity;
@Override
protected paintComponent(Graphics g) {
super.paintComponent(g);
[Code] .....
What I don't get is, if I use this, where would I put the drawRect and stuff to make the other shapes I need? in their class, under the entity.Draw(g) method? or in the display class where it calls the graphic object in the first place?
Last, how can I have my controller class refresh the displays of each of these with the timer I have implemented? Is there a simple way to call one refresh command and have it refresh the drawing of both the paddle and ball simultaneously, or would I need to call a separate refresh command for each object?
I use Canvas, Graphics & JFrame, but not JPanel, how do I add an Image? To see my code: [Java] package pack.script.game; import java.awt. BorderLayout; import java.awt.Canv - Pastebin.com
What do I need to add, or where can I find information on how to add an image? Can I add an image using Graphics? I will import any utils, swings or awts needed. But I don't want to change my code too much.
