  • Problems using Maven to initialize a local thoughtsite (App Engine sample) project in Eclipse

    - by ovr
    This sample app ("thoughtsite") for App Engine contains a pom.xml in its trunk: http://code.google.com/p/thoughtsite/source/browse/#svn/trunk I ran mvn eclipse:eclipse and also tried using m2eclipse to import this source code into an Eclipse project. But I end up with this error despite the fact that I have the Google App Engine plugin and the Google App Engine SDK installed: Exception in thread "main" java.lang.ExceptionInInitializerError at com.google.appengine.tools.info.SdkImplInfo.<clinit>(SdkImplInfo.java:19) at com.google.appengine.tools.util.Logging.initializeLogging(Logging.java:36) at com.google.appengine.tools.development.DevAppServerMain.main(DevAppServerMain.java:82) Caused by: java.lang.RuntimeException: Unable to discover the Google App Engine SDK root.

No idea how to get this project working.

  • Accessing 2D array and passing string to label.text

    - by Amir
    Hi. I'm trying to create 2D array and initialize it with NSStrings. When I try to copy content of a cell from the array to a label.text, the application crashes. NSMutableArray *array = [NSMutableArray arrayWithCapacity:0]; [array addObject:[NSMutableArray arrayWithObjects: [NSArray arrayWithObjects: @"0-0", @"0-1", @"0-2", nil], [NSArray arrayWithObjects: @"1-0", @"1-1", @"1-2", nil], [NSArray arrayWithObjects: @"2-0", @"2-1", @"2-2", nil], nil]]; label.text = [[array objectAtIndex:0] objectAtIndex:0]; Any idea why and what am I doing wrong?

  • 2D World design question

    - by Maciek
    I'm facing a problem which is probably extremely common in game-design. Let's assume that we've got a 2D world The world's size is M x N rect The world may contain some items in it The items have (x,y) coords The world can be browsed via a window that is physically (m x n) large. The browser window can be zoomed in / out The browser window can be panned up/down + left right, while in the extents of the world's rect. How should I go about implementing this? I'm especially concerned about the browser window. Can anyone recommend any good reads ? This is not a homework - it's more of a task which I've set myself to complete.

  • Surface Detection in 2d Game?

    - by GamiShini
    I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

  • WPF component for 2D tree diagram

    - by pdm2011
    I'm looking for a well-documented, supported WPF component that provides an API for visualisation of 2D tree diagrams. Ideally something easy to use, customisable (i.e. supports various flavours of nodes and splines) and preferably with automated layout control. Tools that look good so far are GoXam (http://www.nwoods.com/components/silverlight-wpf/goxam-overview.htm) and yFiles WPF (http://www.yworks.com/en/products_yfileswpf_about.html). Just wondering if anyone has experience with either of these, or can recommend an alternative? Thanks!

  • declaring a 2D array of pointer objects

    - by Tyler Stennette
    I'm having a tough time figuring out how to instantiate a 2D array of pointer objects. Here is how I'm doing it: Pieces* chessBoard[9][9]; When I want to set it to an actual object pointer, I'm doing the following: chessBoard[1][1] = new Rook(p1Rook); Rook is a class that inherits attributes from the Pieces class and p1Rook is a char variable set to 'R'. This class also implements virtual functions (not pure virtual) from Pieces such as move() or getPiece() that are unique to the particular chess piece. However, when I compile my program, I get the following error: ChessBoard.cpp:69: error: expected type-specifier before ‘Rook’ ChessBoard.cpp:69: error: cannot convert ‘int*’ to ‘Pieces*’ in assignment Can someone please explain what I should change to get rid of this rather annoying persistent error? I would appreciate it.

  • Rewriting a simple Pygame 2D drawing function in C++

    - by Dominic Bou-Samra
    I have a 2D list of vectors (say 20x20 / 400 points) and I am drawing these points on a screen like so: for row in grid: for point in row: pygame.draw.circle(window, white, (particle.x, particle.y), 2, 0) pygame.display.flip() #redraw the screen This works perfectly, however it's much slower then I expected. I want to rewrite this in C++ and hopefully learn some stuff (I am doing a unit on C++ atm, so it'll help) on the way. What's the easiest way to approach this? I have looked at Direct X, and have so far followed a bunch of tutorials and have drawn some rudimentary triangles. However I can't find a simple (draw point).

  • XNA 2d camera with arbitrary zoom center

    - by blooop
    I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

  • Visit neighbor of a position in a 2d-array

    - by Martin
    I have the following two dimensional array: static int[,] arr = new int[5, 5] { { 00, 00, 00, 01, 00 }, { 00, 00, 01, 01, 00 }, { 00, 00, 01, 01, 00 }, { 00, 00, 01, 01, 00 }, { 00, 00, 00, 01, 00 }, }; I have to a implement a method called Hit(int x, int y). When we hit a 0 in the array (i.e. Hit(0, 0), Hit(1, 1), but not Hit(3, 0)) I would like all the adjacent zeros to the zero we hit to be incremented by 10. So if I call Hit(1, 1), the array should become the following. static int[,] arr = new int[5, 5] { { 10, 10, 10, 01, 00 }, { 10, 10, 01, 01, 00 }, { 10, 10, 01, 01, 00 }, { 10, 10, 01, 01, 00 }, { 10, 10, 10, 01, 00 }, }; Any idea how I could implement that? It sounds to me like a Depth First Search/Recursive sort-of algorithm should do the job, but I haven't been able to implement it for an 2d array. Thanks for the help!

  • Is there a search engine that indexes source code of a web-page?

    - by Dexter
    I need to search the web for sites that are in our industry that use the same Adwords management company, to ensure that the said company is not violating our contract, as they have been accused of doing. They use a tracking code in the template of every page which has a certain domain in the URL, and I'm wondering if it's possible "Google" the source code using some bot that crawls the code rather than the content? For example, I bought an unlimited license for an image gallery, and I was asked to type the license number in a comment just before the script. I thought it was just so a human could look at the source and find out if someone paid, but it turned out that it was actually that they had a crawler looking for their source code and that comment. If it ran across the code on your site, it would look for the comment, and if it found one, it would check to see if it was an existing one. If not, it would first notify you of your noncompliance, and then notify the owner of the script. Edit: I'm looking to index HTML and JavaScript only, not the server-side languages or Java.

  • Quartz 2D animating text?

    - by coure06
    i have to animate text around a circle. The text will also scale up/down. Whats the best approach to accomplish this? (i am using Quartz 2D) My approach is: -- Calculate point using sin and cos methods. -- Move Pen there and draw text with alpha and size. -- Clear the screen -- Calculate next point using sin and cos methods. -- Move pen there and draw text with alpha and size. -- clear the screen so on... any better way?

  • Finding the sum of 2D Arrays in Ruby

    - by Bragaadeesh
    Hi, I have an array of two dimensional Arrays. I want to create a new two dimensional array which finds the sum of these values in the 2D arrays. Sum at x,y of new array = Sum at x,y of arr1 + Sum at x,y of arr2 + .... |1,2,4| |1,1,1| |1,1,1| |2,4,6| |1,1,1| |1,1,1| |2,4,6| |1,1,1| |1,1,1| |2,4,6| |1,1,1| |1,1,1| Now adding the above two dimensional arrays will result in, |3,4,6| |4,6,8| |4,6,8| |4,6,8| How to achieve this in Ruby (not in any other languages). I have written a method, but it looks very long and ugly.

  • Creating a 2d matrix from an array (java)

    - by anna
    I'm supposed to write a method that creates a 2d matrix from an array, for instance: ({1, 2, 3, 4}, 3) should return the matrix {{1, 2, 3}, {4}} public class Matrix { public static int[][]toM(int[] array, int a) { int[][]matrix = new int [(array.length + a- 1)/ a][a]; for (int i = 0; i < array.length; i++){ int value = array[i]; value = value++; for (int row = 0; row < (array.length + a- 1)/a; row++) { for (int col = 0; col < a; col++) { matrix[row][col]= value++; } } } return matrix; } } I'm getting [[4, 5, 6], [7, 8, 9]]?

  • How can I save state from script in a multithreaded engine?

    - by Peter Ren
    We are building a multithreaded game engine and we've encountered some problems as described below. The engine have 3 threads in total: script, render, and audio. Each frame, we update these 3 threads simultaneously. As these threads updating themselves, they produce some tasks and put them into a public storage area. As all the threads finish their update, each thread go and copy the tasks for themselves one by one. After all the threads finish their task copying, we make the threads process those tasks and update these threads simultaneously as described before. So this is the general idea of the task schedule part of our engine. Ok, well, all the task schedule part work well, but here's the problem: For the simplest, I'll take Camera as an example: local oldPos = camera:getPosition() -- ( 0, 0, 0 ) camera:setPosition( 1, 1, 1 ) -- Won't work now, cuz the render thread will process the task at the beginning of the next frame local newPos = camera:getPosition() -- Still ( 0, 0, 0 ) So that's the problem: If you intend to change a property of an object in another thread, you have to wait until that thread process this property-changing message. As a result, what you get from the object is still the information in the last frame. So, is there a way to solve this problem? Or are we build the task schedule part in a wrong way? Thanks for your answers :)

  • Need to Determine the Engine Status?

    - by user702295
    If you need to establish the status of the engine, begin with this SQL: select status, engine, engine_version,fore_column_name from dm.forecast_history The status of an engine run is stored in the FORECAST_HISTORY table, in the “status” field.  We can also find in that table the FORE_COLUMN_NAME field. This field includes the name of the column in SALES_DATA in which the relevant forecast is stored. Here are the possible statuses: -1, -2 : The engine failed in the initialization phase.  Which means, before the engine manager created the engines.  0 : The engine stopped in the optimization phase.  Which means, after the engines were created.  1: The engine finished the run successfully.  2: Forecast was never calculated for the relevant column that is mentioned in FORE_COLUMN_NAME.

  • 2d array, using calloc in C

    - by BigBirdy
    Hi, I'm trying to create a 2D array of chars to storage lines of chars. For Example: lines[0]="Hello"; lines[1]="Your Back"; lines[2]="Bye"; Since lines has to be dynamically cause i don't know how many lines i need at first. Here is the code i have: int i; char **lines= (char**) calloc(size, sizeof(char*)); for ( i = 0; i < size; i++ ){ lines[i] = (char*) calloc(200, sizeof(char)); } for ( i = 0; i < size; i++ ){ free(lines[i]); } free(lines); I know that each line can't go over 200 chars. I keep getting errors like "error C2059: syntax error : 'for'" and such. Any ideas of what i did wrong?

  • XNA 2D mouse picking

    - by Corndog
    I'm working on a simple 2D Real time strategy game using XNA. Right now I have reached the point where I need to be able to click on the sprite for a unit or building and be able to reference the object associated with that sprite. From the research I have done over the last three days I have found many references on how to do "Mouse picking" in 3D which does not seem to apply to my situation. I understand that another way to do this is to simply have an array of all "selectable" objects in the world and when the player clicks on a sprite it checks the mouse location against the locations of all the objects in the array. the problem I have with this approach is that it would become rather slow if the number of units and buildings grows to larger numbers. (it also does not seem very elegant) so what are some other ways I could do this. (Please note that I have also worked over the ideas of using a Hash table to associate the object with the sprite location, and using a 2 dimensional array where each location in the array represents one pixel in the world. once again they seem like rather clunky ways of doing things.)

  • 2D Ball Collisions with Corners

    - by Aaron
    I'm trying to write a 2D simulation of a ball that bounces off of fixed vertical and horizontal walls. Simulating collisions with the faces of the walls was pretty simple--just negate the X-velocity for a vertical wall or the Y-velocity for a horizontal wall. The problem is that the ball can also collide with the corners of the walls, where a horizontal wall meets with a vertical wall. I have already figured out how to detect when a collision with a corner is occurring. My question is how the ball should react to this collision--that is, how its X and Y velocities will change as a result. Here's a list of what I already know or know how to find: *The X and Y coordinates of the ball's center during the frame when a collision is detected *The X and Y components of the ball's velocity *The X and Y coordinates of the corner *The angle between the ball's center and the corner *The angle in which the ball is traveling just before the collision *The amount that the ball is overlapping the corner when the collision is detected I'm guessing that it's best to pretend that the corner is an infinitely small circle, so I can treat a collision between the ball and that circle as if the ball were colliding with a wall that runs tangent to the circles at the point of collision. It seems to me that all I need to do is rotate the coordinate system to line up with this imaginary wall, reverse the X component of the ball's velocity under this system, and rotate the coordinates back to the original system. The problem is that I have no idea how to program this. By the way, this is an ideal simulation. I'm not taking anything like friction or the ball's rotation into account. I'm using Objective-C, but I'd really just like a general algorithm or some advice. Many thanks if anyone can help!

  • java 2D and swing

    - by user384706
    Hi, I have trouble understanding a fundamental concept in Java 2D. To give a specific example: One can customize a swing component via implementing it's own version of the method paintComponent(Graphics g) Graphics is available to the body of the method. Question: What is exactly this Graphics object, I mean how it is related to the object that has the method paintComponent? Ok, I understand that you can do something like: g.setColor(Color.GRAY); g.fillOval(0, 0, getWidth(), getHeight()); To get a gray oval painted. What I can not understand is how is the Graphics object related to the component and the canvas. How is this drawing actually done? Another example: public class MyComponent extends JComponent { protected void paintComponent(Graphics g) { System.out.println("Width:"+getWidth()+", Height:"+getHeight()); } public static void main(String args[]) { JFrame f = new JFrame("Some frame"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setSize(200, 90); MyComponent component = new MyComponent (); f.add(component); f.setVisible(true); } } This prints Width:184, Height:52 What does this size mean? I have not added anything to the frame of size(200,90). Any help on this is highly welcome Thanks

  • 2D Platformer Collision Problems With Both Axes

    - by AusGat
    I'm working on a little 2D platformer/fighting game with C++ and SDL, and I'm having quite a bit of trouble with the collision detection. The levels are made up of an array of tiles, and I use a for loop to go through each one (I know it may not be the best way to do it, and I may need help with that too). For each side of the character, I move it one pixel in that direction and check for a collision (I also check to see if the character is moving in that direction). If there is a collision, I set the velocity to 0 and move the player to the edge of the tile. My problem is that if I check for horizontal collisions first, and the player moves vertically at more than one pixel per frame, it handles the horizontal collision and moves the character to the side of the tile even if the tile is below (or above) the character. If I handle vertical collision first, it does the same, except it does it for the horizontal axis. How can I handle collisions on both axes without having those problems? Is there any better way to handle collision than how I'm doing it?
