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?

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.
I'm not even sure if that is the right question to ask. I've been confused by what is A Graphics object for a while now, I used to think that it is simply a tool to use to change colors and draw to specific container(ie JFrame, JPanel).

View Replies View RelatedI've been assigned to create a Black Jack game with a gui. In this game I've created a seperate Player and Dealer class, and both initiated them, however when I try to call a Player object in a certain way I get a null pointer reference. (It should be noted that the Player object is an array)
public void runGame(){
while(running){
while(dealer.getPoints() <=19){
int count=0;
[Code] .....
And this is how I've initilized the Player class in the constructor
Player[] players = new Player[numberofplayers];
for(int i=0; i<numberofplayers; i++){
players[i] = new Player(i);
players[i].setDeck(d1);
gui.add(players[i].getPanel());
}
What I don't get is if I change players[i] to dealer, it works fine.
Opoly works this way: The board is a circular track of variable length (the user determines the length when the game app runs). There is only one player, who begins the game at position 0.
Thus, if the board length is 20, then the board locations start at position 0 and end at position 19. The player starts with a reward of 100, and the goal of the game is to reach or exceed reward value 1000. When this reward value is reached or exceeded, the game is over. When the game ends, your program should report the number of turns the player has taken, and the final reward amount attained.
In Opoly the game piece advances via a spinner - a device that takes on one of the values 1, 2, 3, 4, 5 at random, with each of the five spin values equally likely.
Although the board is circular, you should draw the state of the board as a single "line", using an 'o' to represent the current player position, and * represent all other positions. Thus if the board size is 10, then this board drawing:
**o******
means that the player is at location 2 on the board.
Here are the other Opoly game rules:
If your board piece lands on a board cell that is evenly divisible by 7, your reward doubles.
If you land on the final board cell, you must go back 3 spaces. Thus if the board size is 20, the last position is position 19, and if you land there, you should go back to position 16. (If the position of the last cell is evenly divisible by 7, no extra points are added, but if the new piece location, 3 places back, IS evenly divisible by 7, then extra points ARE added).
If you make it all the way around the board, you get 100 points. Note that if you land exactly on location 0, you first receive 100 extra points (for making it all the around), and then your score is doubled, since 0 is evenly divisible by 7,
Every tenth move (that is, every tenth spin of the spinner, move numbers 10,20,30,... etc.), reduces the reward by 50 points. This penalty is applied up front, as soon as the 10th or 20th or 30th move is made, even if other actions at that instant also apply. Notice that with this rule it's possible for the reward amount to become negative.
Here is the driver class for the game:
import java.util.*;
public class OpolyDriver{
public static void main(String[] args){
System.out.println("Enter an int > 3 - the size of the board");
Scanner s = new Scanner(System.in);
int boardSize = s.nextInt();
[Code] ....
heres the methods:
REQUIRED CODE STRUCTURE: Your Opoly class must include the following methods (in addition to the Opoly constructor) and must implement the method calls as specified:
playGame - The top-level method that controls the game. No return value, no parameters. Must call drawBoard, displayReport, spinAndMove, isGameOver.
spinAndMove - spins the spinner and then advances the piece according to the rules of the game. No return value, no parameters. Must call spin and move.
spin - generates an integer value from 1 to 5 at random- all equally likely. Returns an integer, no parameters.
move - advances the piece according to the rules of the game. No return value, takes an integer parameter that is a value from 1 to 5.
isGameOver - checks if game termination condition has been met. Returns true if game is over, false otherwise. No parameters.
drawBoard - draws the board using *'s and an o to mark the current board position. Following each board display you should also report the current reward. No return value, no parameters.
displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward. No return value, no parameters.
Im trying to make a tic tac toe game that you play against the computer using a random number generator and two dimensional arrays for the game board. Im not trying to make a GUI, the assignment is to have the board in the console, which I have done.

He 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 have a JPanel embedded in a JScrollPane. I draw in the JPanel, using the paint() method. I have to draw some shapes that can go far in the y direction, that's why I put my JPanel in a scroll pane, in order to scroll down to be able to discover the shapes down. But even though I put my JPanel in a JScrollPane, it soon blocks in the y direction and does not show the shapes far in the y direction.
Note: I used a GridBagConstraints which is correctly set, with its fill attribute etc.
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 can i do the coding? such as adding listeners to the shapes?

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
