Swing/AWT/SWT :: 2D Spaceship Game - Image Rotation And Position
Aug 29, 2014I'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.
import java.util.*;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.awt.geom.AffineTransform;
import javax.swing.*;
import java.lang.Math.*;
import java.io.*;
import javax.imageio.*;
[Code] .....
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.
JavaFX 2.0 :: Image Overlay Rotation Interpolation Error
Jun 12, 2015I'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).
Here I surrounded the errors:
The image:
The stencil:
And here is the code:
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.*;
import javafx.scene.effect.BlendMode;
import javafx.scene.image.*;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;

Centered Alignment For Console
Feb 8, 2015"Write a java application that displays the following patterns separately one below the other.
Use for loops to generate the patterns. There are 4 Triangle patterns.
All asterisks (*) should be printed by a single statement of the form System.out.print('*');
This is 4-different patterns, not 1-pattern."
The first 2 triangles are right angles and is simple to make with a loop with in a loop
The 3rd triangle is like an inverted christmas tree and the 4th one is a christmas tree. ( It's not showing properly on the board so i deleted it). I can't seem to make the 3rd and 4th triangle line up properly it looks like this (the _ represents blank spaces on the console)
_____*_____
_____**_____
____***_____
____****_____
___*****____
___******_____
__*******
__********____
Notice how the sides of the triangle isn't straight and the triangle looks like its dancing, the assignment requires it to be a straight line. is there anyway to do this? This is suppose to be the output. all the lines of the triangle is straight and not jagged ...
public class myclass {
public static void main(String[] args) {
int counter = 1;
int counter2 = 1;
while (counter != 11){
EmptyLine();
[Code] .....
My code for those particular triangle is in the work because I cant figure out how to make it look like that.
Swing/AWT/SWT :: Why Must All Components In A Container Have The Same Alignment
Dec 10, 2014I have a JPanel with vertical BoxLayout. It contains four components. I set the JPanel to LEFT_ALIGNMENT, which has no effect on its components. I set the first component to LEFT_ALIGNMENT, which has no effect. Only after I have set all four components to LEFT_ALIGNMENT do any of them align properly.
This suggests that it is impossible to have varying alignments in a container. They must all be the same alignment.
I accept that this is just the way things are: "Java works in mysterious ways." And I'm sure that it is possible to work around this limitation by stacking boxes that themselves have different internal alignments.
But I still wonder what in the world was going on in the minds of the Java developers. Is there a rational reason for this oddity?
This raises my most serious criticism of Swing: the hidden gotcha. Swing is a tangled mess of cross-connecting requirements that are impossible to divine by simple inspection of the documentation. If you want to use, say, a JRadioButton, it's not enough to study the documentation on JRadioButtons; you must also consult lots of documents for which there is no obvious connection to JRadioButton other than it being part of Swing.

View Replies View RelatedGraphics Rotation In Swing
Feb 3, 2014How 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
2D Circle Texture Rotation?
Jan 11, 2015So 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);

Swing/AWT/SWT :: AffineTransform - Rotation Is Being Ignored When Set Transform
May 31, 2014I'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;

JavaFX 2.0 :: Panel Effect - Rotation Along Its Y Axis
Dec 14, 2014I 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.

May 22, 2014We 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.

How To Turn Image Into Tiled Image
Nov 21, 2014I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
tile[i]=arr[i];
}
return tile;
}
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
for(int j=0; j<arr[i].length;j++){
tile[j]=(tile[j])+(arr[i]);
}
}
return tile;
}
