I have been following a 2d side scroller tutorial in java and have got the basics working, I changed the code a bit to make it so that the tiles and background are always moving, this worked as i intended.Within the character class:
if (speedX < 0) {
centerX += speedX;
}
if (speedX == 0 || speedX < 0) {
bg1.setSpeedX(0);
bg2.setSpeedX(0);
[code]....
I wanted a way to make it so that if the character moves left, the tiles + background move slower. I am having issues with variable scope and setters/getters. Within the main game class, I have the code:
case
KeyEvent.VK_LEFT:
character.moveLeft();
character.setMovingLeft(true);
break;
How can i include an if statement within the tile class that reads whether the character is moving left (determined from a keyPressed event in the main game class) and adjusts the speed of the tiles accordingly?I want to write something to the effect of:
I am trying to display two JComboBoxes side by side. I can successfully display them as part of a BorderLayout if they are in the North and East, but when I try to display them side by side in the same area, eg North, only one of the combo boxes gets displayed.
I'm using SchedulerExecutorServices to Schedule a task. My Question is how can i schedule more than one task side by side:
Here is what I'm doing:

I need to write server side program(Servlet) which must be access by several requests at same time.how to handle this using java? Do i need to use queue or multiple instance of same class. Any example server method which returns the results based on ID
public String getResut(int id){
1)get db connection 2)get the result from db 3) retun the result }
I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){ while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){ rotateBottomClockwise(1); System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is: alignment is: W-G and tops: R-R NOW ITS ALIGNED even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out ** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube ** ** ** R6 W5 O4 ** ** ** ** ** ** R3 W2 O1 ** ** ** B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube B2 G5 R8 W4 R5 Y6 O2 B5 G8 O7 W8 R9 B7 B8 B9 R1 R4 R7 ** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube ** ** ** Y2 Y5 Y8 ** ** ** ** ** ** B1 G6 W7 ** ** ** ** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube ** ** ** R2 O5 G2 ** ** ** ** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2
I am very much new to jsp and servlet. I want to set global error page for every exception occured at server side. I am trying with following code , but something is going wrong and I am not able to c error page.
I need to implement Oauth2 with facebook to get authencation. I tried to write a servlet with the method Service, and i got the code thah i have to use in a second request.
Now i need to send a request at this URL :
1) [URL] .....
and wait for a responce with an URL that have the access_token to use with facebook
2) [URL] ....
Is it Possible in a single Servlet after i receive the "code" to send a second request to the URL in 1 and get the response with URL in 2 to retrieve the access_token?? if yes....how??
Basically I have a program that paints a simple object image. There are 5 of these objects altogether and different classes and methods have been set up to do this and this works correctly. The program currently also asks the user if they would like to change the colour of this object shape, and which shape they would like to change (user inputs a number 1-5) then the program will change the colour of this shape.
But the new task is for the user to input a number (1-5) to which shape they would like to MOVE position of. Hhow this would be done? Would there need to be different methods for changePositionX, changePositionY? The user needs to input the X and Y co ordinates and then this will move the selected shape to its NEW position in the current JFRAME.
I have a class that works only when in the default package. If I move the class to a package I receive UnsatisfiedLinkError.
This is the class in the default package(this works fine):
[code] public class CsharpConsumer { private native int reigsterAssemblyHandler(String str); public CsharpConsumer() { String dir = System.getProperty("user.dir"); System.load(dir+"dllscardJNICsharpBridge.dll"); int reigsterAssemblyHandler = reigsterAssemblyHandler(dir+"dllscard"); } } [/code]
If at the top of this class I add "package DLLUtils;"
the error is "Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError:
try to make a game in this code i am trying to make the basics i have made a mouse it should move the game code is
import java.applet.Applet; import java.awt.*; public class Game extends gameLoop { public void init() { setSize( 854 , 480); Thread th = new Thread (this);
I'm learning about the printf command, and when I have it, it is not letting me ad an input. Here is my quick little program:
import java.util.Scanner; public class TestingPrintF { public static void main(String[] args) { // Create a Scanner Scanner input = new Scanner(System.in);
[Code] ....
The first section works good, but when i move down to the second part it just automatically finishes without letting me enter a phrase.
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.
I am writing code for a simple java game. The problem I am running into is that I have a moving icon (J button) that is controlled using the keyboard (arrows) and I also have stationary icons (J button). Is there a way to keep the moving icon from passing over the stationary icon? I would like the stationary icon to act like a wall.
I am trying to make a simple platformer game in Java. When I try to move the character I made it only moves over then immediately back

I have made a little chat program with java(ecplise) but i want build it and if a user opens it is is going to run in the backgroundprocess. I don't know if i have to edit my code or Export it differently.
i am trying to make a platform game in java and to do this im trying to make a scrolling bacground. i can get the background image to scroll. However, i cant get the image to scroll forever, here is the code.
GamePanel class ( the jpanel ) public class GamePanel extends JPanel implements ActionListener{ static ArrayList<BackGround> store = new ArrayList<BackGround>(); public GamePanel(){ setFocusable(true); Timer time = new Timer(5,this); time.start(); store.add(new BackGround(0,-200));
the problem i have is that i want the bacground to loop. however, once the first instance of the background is done scrolling it freezes and doesnt load anymore. here is the code for adding a new background to the list
I am trying to go about making this applet a bit different then normal. The issue I am having is it is drawing an applet but, not the right dimensions, it's able to be resized, lastly the background color is not being set. I mean, I suppose I could call paint() and just draw it out but, I read that I could make the applet pop out to the dimensions I would like. None of this is working sadly.
I was making this program and I ran into an issue which is that I cant seem and understand how to get the numbers to go to the other side of the table
I had to make a program that converted 1-9 miles to kilometers and the other side 25-65 (increments of 5) kilometers to miles and thats the part I am having trouble with.
Here is what I have so far
import java.util.Scanner; public class MilesAndKilos { public static void main(String[] args) { int miles; double kilometers=1.60934;
[Code] ....
and this is how I want it to look
MilesKilometersKilometers Miles 1 1.609 | 25 12.430 2 3.219 | 30 15.538 3 4.828 | 35 # here 4 6.437 | 40 # here 5 8.047 | 45 # here 6 9.656 | 50 # here 7 11.265 | 55 # here 8 12.875 | 60 37.290 9 14.484 | 65 40.398
I want to ask that, when a server listen to A port and it accepts a request from a client then the server accepts the request using accept method,but how does the server get the info about the client like wat is the port no and ip address of the client,I read a answer regarding this that Server never gets the port no of client only the ip address and it connects to client using a connection stream but as far I know from networking, a device must have the ip address and port no of the device it wants to connect to.
for measurement of application security isn't not allow to change this parameter to client , so the problem when I access for application and I open a new page via linker for print for example and I would access for my initial page to make change or modify my initial page it s no possible to make any modification because I have a empty bean , but if the state saving is a client I haven't a problem because a tree map is stored in client browser, so my version of JSF is 1.1.1 ,
