I'm making my 2D Java game, in my own style, in my own way. I'm trying to make it as code efficient as possible and compact, it usually is easier to change that way. I'm going to use BufferedImage subdivision on tilesets to take out tiles that I need, rather than creating multiple images with a tile each. Now, I've made multiple water tiles, for how they would be arranged differently.
So let's say you have a single water spot, it will be circular, you have two water spots, you have a tile-thick line with circular ends like two little water spots connected, this makes the game look more advanced, better, more realistic and good in many other ways. But, I found that an avarage amount of shapes needed is 25. I thought, how could I make this more efficient?
Could it be possible to use like shape cutting tools or something that would take out a specific shape of a single water tile to leave out all the different shapes, this is a good idea because I could use these tools for all kinds of different tiles in order to make specific features. By tools I mean simple black shapes which will remove the unwanted parts of the tile to form the wanted shape.
I am trying to custom graphic class..,My task is to replace the specific area color of the image when i select the area & pick the color..,If i choose the hand / body of the T-shirts means the color can change by the user..,
I want to practice chopping my code into small objects so they can be easily reused and replaced/maintained etc. So I'm looking to separate this small program into three separate files, one main with the main function to make a window, one to make the DrawPanel for "animating", and one for the controlling with the KeyListener.
import javax.swing.*; //Graphics API import java.awt.*; //BorderLayout API import java.awt.event.KeyEvent; import java.awt.event.KeyListener; public class KeyAnimate { int x = 0; //X Coords int y = 0; //Y Coords int z = 0; //Z to Keep going forever
I am trying to write a specific byte sequence to a specific memory location on a removable storage drive. Does Java allow me a way to do this? I know the dangers in accessing memory, but the memory location of the data that will be written will never change.
- from the main class will arrive three variable (String name_used, int level_choose, int level_result)
I have a .txt file with this kind of formatting:
mario 1 1 0 1 0 1 carlo 0 0 0 1 1 0 ...
Where I use 1 and 0 in the main for write if the level (you see that the numbers are always sixr? are egual to six level existing) BEFORE is done correct or wrong
- when in the main a user make a level a feedback coming back from the class level saying if the user made the count correctly or wrong. and i wanna replace the value (1 or 0) in the txt file with the new level result.
So i have all what i need as parameters i think.
name_used to look for the correct line in .txt file with .indexOf level_choosed to go throught the correct index of that line level_result (1 or 2) to be replaced with the existing one
Java Code:
public void salvaRisultati(String name_used, int level_choosed, int result_of_level) throws FileNotFoundException{ } } mh_sh_highlight_all('java');
I have some problem to understand the way to make this:
In my main class a user can save his name in a txt file (and the system initially will add 6 value equals to 0) than he can choose between 6 level and make it.
example of .txt file data:
mario 0 0 0 0 0 0 carl 0 0 0 0 0 0
AT THIS MOMENT i just made other class and they work, is this new one that is hard for me. I'm trying to make a class that:
1- (first method called verificaRisultati) take name_used and level_choosed from the main and go to check in the .txt file if that level before was done right(1) or wrong(0)
and return something like "before you made this level properly" or "before you made this level incorrectly" AND THEN let the user start with the level.
2- (second method called salvaRisultati) at the end of the level i wanna pass the result (correct/incorrect) to another method of this class that will save the value (1 or 0) associated to the user in the right position.
This is the class that i'm writing:
Java Code:
import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; public class ResultUsers {
[Code] ....
I really need some hint and some code example because I'm stuck. How I can take exactly the line with the user name? How I can correctly split the line in an array and then read/modify the value for that level?
why am I not getting a proper shape of "Leftarrow"? The result should look like the following (the system draws the arrow abnormally, so the beginning should a real ARROW:
*
* *
* *
* * * * * * * * *
* *
* *
*
here is the class:
Java Code: public class LeftArrow extends ShapeBase { private int lengthOfTail; private int widthOfArrowHead;
class shape{ public static void main(String [] args){ for(int x =0 ; x<=6;x++){ for(int y =0 ; x > y ; y++){ System.out.print(x); } System.out.print(" "); } } }
i java a project with java draw golf course and currently working on 2 combo boxes to change shape of the flag on the post and fill color as well on combo box item change. I have below code. as am new to java what to do next.
import java.awt.*; import java.awt.event.ItemEvent; import javax.swing.*; public class GulfCourse extends JPanel{ public void paintComponent( Graphics g){ super.paintComponents(g); //draw green oval
I'm making a program that prints arrows of varying tail length, head width, and displacement.The shape algorithms are working properly, but the displacement isn't working. The first arrow has zero displacement, and the second one is supposed to be bigger and start the print at 10 spaces right and 5 spaces down from the default, but it's not working. I tried changing the displacement settings of the first arrow, and no changes happened, so I know that the positions aren't registering properly in general. How to pass the xAdj and yAdj (displacement) values? I think I have the empty space formula set up, but it's still not running.
Driver: public class Driver { //default values public static final int Arrow_Default_xAdj = 0; public static final int Arrow_Default_yAdj = 0; public static final int Arrow_Default_tail = 5; public static final int Arrow_Default_width = 5;
I'm going to make tiles for my RPG game, instead of drawing each shape of the tile, I will just draw the full tile in a spritesheet. I will create a sprite sheet of shapes that I want to clip somehow or use to cut the original full image into the shape I want. How can I, take a Buffered Image, cut it's shape and perhaps add something, giving me a Buffered Image of a cut tile with possibly added features that I can then draw with Graphics?
I am supposed to Write a program that prints a shape similar to the following shape. Maximize use of loops and minimize use of print statements.
.....* ....** ...*** ..**** ...*** ....** .....*
(without the "...")(i couldn't get it to stay in shape)
This is what i got so far:
Java Code: package assignment7;
public class Exercise3 { public static void main (String[] args) { for (int count =0; count < 4; count++) { for (int j=0; j < count+1; j++) [Code] ....
I am trying to draw at my mouse a certain shape that I have set. I defined some shapes where they extend shape and draw circles and stuff. But when I click on panel it seems the paint doesnt put anything there. Debugger tells me shapes are saved though.
I am currently trying to make a Tetris game, so far I've got a class drawing that extends a JPanel as my canvas, a class Square that is 1 square(20 by 20) and a class LineShape that should draw 4 squares above each other. The class Frame way below is merely to set things up.
Currently i'm able to draw objects of my class Square, so I made a class LineShape that combines both and makes a 4Square long line.
My problem is when I try to draw an object of the class LineShape, it shows nothing, removes what is already painted(the square) and gives an error message:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at LineShape.<init>(Screen.java:96) at Drawing.paint(Screen.java:79)
I put my classes together so you can copy paste and run, make a new screen to start, to see the problem occur, go to the drawing class's paint method and uncomment these lines:
// LineShape shape = new LineShape(this); // shape.paint(g);
Below are my classes:
import javax.swing.*; import java.awt.*; public class Screen { private Frame frame; private Frame inputFrame; private JPanel panel;
I was working on this project, and I have everything working, except that it doesn't change the colors of the shapes in the other window. Here's the code to see what I'm doing wrong:
Java Code:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class JDemo { //Global Variables static Color color0 = Color.blue; //sets the value in the color0 variable to the method Color.blue . static Color color1 = Color.red; //Sets the value in the color1 variable to the method Color.red .
[Code] ....
The button0 is supposed to switch the color in window1, and button1 is supposed to switch the color in window0.
I need to modify the drawShape method to calculate the distance from the starting point (the diameter) of any shape regardless of how many sides I give it, but I have absolutely no clue where to begin with this. The ultimate goal of the program is to calculate the value of pi using the shape that is drawn.
Here is the code:
public class PiTurtle extends Turtle { private double mySize; private int mySides; private double diameter = 0; final static double startX = 590.0; final double startY; public PiTurtle(int nSides)
I am working on a UI in JavaFX and create several instances of a custom control class. The control consists of a Pane which wraps several other containers, one of which contains a Circle shape.
At one point, I instance this control and access the Circle shape directly. I transform it's center coordinates (which are always {0.0, 0.0} ) to Scene coordinates. The problem is, the transformation always yields coordinates that correspond to the upper left corner of the control's root pane.
In other words, it's as if the Circle is positioned at the upper left corner of the custom control (when, in fact, it's positioned near the lower right corner).
I have other instanced controls already in the scene, and they do not have this issue - converting the Circle's coordinates to scene coordinates works as it should.
It seems obvious that I'm accessing the Circle too soon - that perhaps the scene graph hasn't been fully traversed for the control and the Circle's position within the control's hierarchy hasn't been updated. I've verified that my attempt to access the Circle's center coordinates occurs after the control's initialize() method is executed, so how to ensure the control's scene graph has been fully updated before I try to manipulate the control...
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 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 .
