I was trying to understand Textures and OpenGL with Java. but the tutorials I find cover such a horribly broad area X_x.Basically I can get a window up, initialize openGL, and draw many repeating blocks on my screen.
I dont specifically care about minecraft. but I would like to learn how to get Many many blocks on the screenand how to apply more than one texture to a block. I cant seem to load two textures at a time without errors. I have a dumb while loop that includes a few For loops that repeat the blocks.I guess I should learn how to use Arrays to automate the block process ? Im not sure. I started reading about object buffers, but im not sure.
public static void initDisplay()
{
try {
Display.setFullscreen(true);
Display.setVSyncEnabled(true); // Drastically effects updates per second, Camera movement lowers by 98%
I'm writing a java program with opengl and I'm trying to get it where the user would select something like lighting on in a JMenu and then it would turn the lighting on in the house/barn... I have a method called LightOn that I put gl.glEnable(gl.GL_LIGHT0); but it just doesn't seem to turn on when I call it from the action performed... Is there something I'm missing from my code that I'm supposed to use instead since I have tried it with a boolean.. So the boolean starts off as false and when the JMenuItem is clicked the actionPerformed will turn the boolean to true and call the method LightOn. In the display method I have what the light is supposed to be
How can i use multiple textures on a model? I have the .OBJ loader and .MTL loader and everything is working fine. I can use a single texture. But i have a model that has 2 textures. How can i use both of the textures?
I am new to DreamInCode! I was creating a game using OpenGL (and slick for textures).
Using Vector3f, I make coordinates to where my camera is camera'ing (and rotation).
It was working... until I modified something. I only added shaders. When I took the shaders off I think I might of accidentally deleted something. Nonetheless the code looks perfect to me.
On the method "input()" everything runs. No errors are thrown anywhere. I have syso'd the hell outa my code. It shows no signs of breaks. I can, however, move elements I put into my program. I am 100% sure that no other class is breaking my game (soon to be).
What you should look out for: I am not really sure about the glLoadIdentity()'s and glMatrixMode(). I am, knowing a good part of, thinking it could be gluViewPort....
My problem: Can't move my camera even tho it was working before.
I had the opengl display attach to the JFrame before i did the runnable. But after adding the runnable the display now shows up the same size as my screen size. I have tried rearranging the
canvas.setSize(); and the frame.setSize();
but nothing changes the opengl display is still the same size and when i try to close the JFrame first rather then close the display first i get this error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: From thread Thread[AWT-EventQueue-0,6,main]: Thread[main,5,main] already has the context current
which points me to my
Display.destroy();
which im guessing is telling me that i am not properly disposing the display? How to attach the opengl display to the JFrame and fix the error above?
So I need to create a square and make it rotate when the letter R is pressed and then make it stop when the letter R is pressed again. I need make it rotate using a maths equation that I can't figure it out myself right this moment.
Code for square:
package lab2; public class Square { public double [][] vertices = new double[4][2]; //not good to make this public public Square(double x1, double y1, double x2, double y2, double x3, double y3, double x4, double y4) { vertices[0][0]=x1; vertices[0][1]=y1; vertices[1][0]=x2;
[Code] ....
In the Square code there is a method to write an equation to rotate it but I can't figure that part out ....
I have tried running the java application without adding the site to site list in java security tab. But I get a sand box message as APPLICATION BLOCKED BY SECURITY SETTINGS. How to run the java application without adding the site to site list in java security tab.
I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,
I've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src
java File1
I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)

The title of Question might seem old and previously asked.But I have a Question that what is difference between javaSE and Java EE.Although I knew what comes under JavaSE and What is under JavaEE.But My question is that.
What happens when we add PATH in our Environment Variable How does Eclipse or Other IDE use it?
Second Question is.
For Java SE we declare a Path Variable but for Java EE we do not add any library?(I know we add some jar file like for Servlet(Servlet-api.jar) and for EJB(Ejb.jar),But What is actaul difference?
I know about coding in general, Java, C, Python, SQL etc. but I barely know anything about making code come together on the web. I have a vague idea about what things like libraries and frameworks are,I'm interested in making a web application with which relies on Java do to the data processing. The idea is that the user inputs some messages, clicks submit, the text is taken away and processed, and the results are displayed on the screen. I would like the UI to be smooth with a modern look and feel.
Also, I usually do programming on Windows but I could also use Linux, so if I'll come across any specific drawbacks using Windows.
When I try to convert this value, "Testingu2120" (along with UTF coed u2120)comes as a string as part of SOAP response. I need to convert this UTF-8 characters in to a symbol, in this case it is SM (Service Mark) symbol and show it on the UI.
How can we achieve this in JAVA?
I have four different UTF-8 character set to convert.
I would like my application to execute a command in cmd. The command looks like
start "" /D "C:Riot GamesLeague of LegendsRADSsolutionslol_game_client_sln elease s .0.1.55deploy" "League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 95.172.65.26:8088 P3hNrXYZlaM3iJ9ximtzJWHbwLhvbimJ 953089676 EUN1"
So my question is how do I do this?
I tried this, (just copy paste the command):
package MyProject; import java.io.IOException; import java.io.InputStream; public class Cmd { public static void main(String[] args) { try { final Process process = Runtime.getRuntime().exec("start "" /D "C:Riot GamesLeague of
We started learning about tables and have a little program. The teacher gave us an excercise and doesn't works (not running), I receive too many errors. So any simple java program with tables with 20 numbers, that is giving random numbers?
Write a function (or functions) that given a collection of files will produce a sum of integers from each line of each file. Each file can have any number of lines from 1 to N. Each line can contain only one integer and no other alphanumeric characters. All of the numbers from all of the files should be added to the final result. The result is just one number.
For either, what we are looking for is:
1. Clear separation of concerns 2. Well defined objects / interfaces 3. Application of good OO design principles to solve the problem 4. No code duplication 5. Test Driven Development 6. Well refactored code 7. Well tested code

I am trying to run a Powershell command from Java that creates an Active Directory group. I don't get any errors, but it doesn't work either. I can take the output from this class and plug it into the CMD prompt and it works fine.

I'm converting from ASP to Java for a legacy site. I believe the first part of the if statement is right but I'm having an issue within the else staetment. I'm getting date is undefined, I've tried using getYear and getDate but have not been successful.
ASP:
If Request("action") = "results" Then aMonth = Request("selMonth") aDate = cint(Request("selDate")) aYear = cint(Request("selYear")) Else aMonth = UCase(MonthName(Month(Date()),true)) aDate = Day(DateAdd("d",-1,date())) aYear = Year(Date()) End If
how to use JFrames and button and so on in Java. I found this video on youtube and followed it along, however even though my program is virtually identical to his, I'm still getting errors.
Here's the video I was watching: Video
And here's my code:
import javax.swing.*; //Imports JFrame and JButton for use import javax.swing.JFrame; import javax.swing.JPanel; import javax.*; import java.awt.*; import java.awt.event.*; public class swing
[code]....
The reason why I'm importing some many things is I'm trying everything to try fix my problem.
He's the error messages I'm getting:
frame2.add(panel); ^ C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression frame2.add(panel);
[code]....
I used to make the button just create another frame without additional labels but I changed it to be even more similar to his program just to rule everything out. Also initially my program varied quite a bit, I've changed everything to be like his. Even without the ";" error I got, I kept telling me I was not allowed have my class as static, even though the guy in the video has it set to static. Also I don't think my "setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);" is working as it doesn't change color.
I think the problem is with my panel, it isn't adding to the frame for some reason.I'm using TextPad7 and I'm using Win8.
C:UsersWindows 8Documentsswing.java:42: error: '(' or '[' expected frame2.add(panel); ^ C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression frame2.add(panel);
[code]....
I would also like to point out that some of the comments are out of date and are referencing the way the program was before I made it just like his. For example I know my second class isn't inheriting the first class.
