• Getting a texture from a renderbuffer in OpenGL?

  - by Rushyo

  I've got a renderbuffer (DepthStencil) in an FBO and I need to get a texture from it. I can't have both a DepthComponent texture and a DepthStencil renderbuffer in the FBO, it seems, so I need some way to convert the renderbuffer to a DepthComponent texture after I'm done with it for use later down the pipeline. I've tried plenty of techniques to grab the depth component from the renderbuffer for weeks but I always come out with junk. All I want at the end is the same texture I'd get from an FBO if I wasn't using a renderbuffer. Can anyone post some comprehensive instructions or code that covers this seemingly simple operation? EDIT: Linky to an extract version of the code http://dl.dropbox.com/u/9279501/fbo.cs Screeny of the Depth of Field effect + FBO - without depth(!) http://i.stack.imgur.com/Hj9Oe.jpg Screeny without Depth of Field effect + FBO - depth working fine http://i.stack.imgur.com/boOm1.jpg

• Finding the endpoint of a named bone in Irrlicht

  - by Boreal

  I'm making a tank game that will have multiple tanks. I want to be able to define the weapon placements using bones that I can add right inside the modelling program (Blender to be exact). All tanks will have a bone called Body and a bone called Turret, and then names like Cannon0 and PickupGun for where the shots will be fired from that are attached to the Turret bone. Is there some way to find the absolute end position of a bone that I choose by name?

• My image is not showing in java, using ImageIcon

  - by user1048606

  I'd like to know why my images are now showing up when I use ImageIcon and when I have specified the directory the image is in. All I get is a black blank screen with nothing else on it. import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; import java.awt.Image; import java.awt.event.KeyEvent; import java.util.ArrayList; import javax.swing.ImageIcon; // Class for handling key input public class Craft { private int dx; private int dy; private int x; private int y; private Image image; private Image image2; private ArrayList missiles; private final int CRAFT_SIZE = 20; private String craft = "C:\\Users\\Jimmy\\Desktop\\Jimmy's Folder\\programs\\craft.png"; public Craft() { ImageIcon ii = new ImageIcon(craft); image2 = ii.getImage(); missiles = new ArrayList(); x = 40; y = 60; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public ArrayList getMissiles() { return missiles; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); // Shooting key if (key == KeyEvent.VK_SPACE) { fire(); } if (key == KeyEvent.VK_LEFT) { dx = -1; } if (key == KeyEvent.VK_RIGHT) { dx = 1; } if (key == KeyEvent.VK_UP) { dy = -1; } if (key == KeyEvent.VK_DOWN) { dy = 1; } } // Handles the missile object firing out of the ship public void fire() { missiles.add(new Missile(x + CRAFT_SIZE, y + CRAFT_SIZE/2)); } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = 0; } if (key == KeyEvent.VK_RIGHT) { dx = 0; } if (key == KeyEvent.VK_UP) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } }

• Spherical to Cartesian Coordinates

  - by user1258455

  Well I'm reading the Frank's Luna DirectX10 book and, while I'm trying to understand the first demo, I found something that's not very clear at least for me. In the updateScene method, when I press A, S, W or D, the angles mTheta and mPhi change, but after that, there are three lines of code that I don't understand exactly what they do: // Convert Spherical to Cartesian coordinates: mPhi measured from +y // and mTheta measured counterclockwise from -z. float x = 5.0f*sinf(mPhi)*sinf(mTheta); float z = -5.0f*sinf(mPhi)*cosf(mTheta); float y = 5.0f*cosf(mPhi); I mean, this explains that they do, it says that it converts the spherical coordinates to cartesian coordinates, but, mathematically, why? why the x value is calculated by the product of the sins of both angles? And the z by the product of the sine and cosine? and why the y just uses the cosine? After that, those values (x, y and z) are used to build the view matrix. The book doesn't explain (mathematically) why those values are calculated like that (and I didn't find anything to help me to understand it at the first Part of the book: "Mathematical prerequisites"), so it would be good if someone could explain me what exactly happen in those code lines or just give me a link that helps me to understand the math part. Thanks in advance!

• How do I render terrain in a 2.5D perspective, like in the game Don't Starve?

  - by Hamdan

  I have experience in making 2D side scroller games such as Terraria, but now I want to challenge myself and make a game that has a 2.5D perspective. The game I am trying to mimic is Don't Starve. Right now my focus is on figuring out how to render the ground. I am having a hard time figuring out how they generated the ground, and then rendered it. The way I think they rendered the ground is by first painting the ground in some paint program, and then somehow manipulating that flat image so that it appears to have depth. I am completely confused by how you would actually render that type of terrain. I want the terrain to have the following features: Look like the terrain in Don't Starve, here is a video showing the terrain in Don't Starve The terrain will be flat, and the camera's angle and perspective will be fixed Any tips and hints will be appreciated, Thank you in advance. (I am working in Java, using the Light Weight Java Game Library (LWJGL).)

• How can I port a MonoGame Windows Phone 8 game to iOS?

  - by Homer_Simpson

  I downloaded the trial version of Xamarin Studio and installed it on my iMac. In addition, I installed Xcode on my iMac so that I can use the iPhone emulators in Xamarin Studio. But I don't know how to use my MonoGame Windows Phone 8 source files in a Xamarin iPhone project. How can I use my Windows Phone code in an iPhone project? Can I import all my existing classes(for example Game1.cs) in an iPhone project without changing something? How can I port a MonoGame Windows Phone 8 game to iOS?

• Finding diagonal objects of an object in 3d space

  - by samfisher

  Using Unity3d, I have a array which is having 8 GameObjects in grid and one object (which is already known) is in center like this where K is already known object. All objects are equidistant from their adjacent objects (even with the diagonal objects) which means (distance between 4 & K) == (distance between K & 3) = (distance between 2 & K) 1 2 3 4 K 5 6 7 8 I want to remove 1,3,6,8 from array (the diagonal objects). How can I check that at runtime? my problem is the order of objects {1-8} is not known so I need to check each object's position with K to see if it is a diagonal object or not. so what check should I put with the GameObjects (K and others) to verify if this object is in diagonal position Regards, Sam

• I love video games and know I want to work in the sector but hate programming

  - by normyp

  I just hate how I'll put in 8-10 hours in and get little to nothing back. The return results for your efforts seem to be pathetically small the majority of the time and I don't find that rewarding enough for me to put in the time and effort to learn programming and make myself better. I've heard game design is fun and I think I'd love that but apparently you can only get into that really if you can program, is that true? I feel a bit lost because I'm doing a degree in Games Technology and am worried that I'm sending myself into a job I'll hate.

• Alternatives to the GPL

  - by Bane

  I made a game, and I am currently making a game engine. I want them both to be completely free and open source. What license should I choose? I was reading a bit on GPL, but that seems to be more suited for system code and libraries, AFAIK, as it doesn't permit the use of code for proprietorial software - which, in turn, implies that the code can be used in the first place. I can see that, obviously, game engines can be considered libraries, and therefor be used, but what about game code? Is there an alternative to GPL?

• Video playback in games - formats & decoding

  - by snake5

  What free / non-restrictive open-source solutions (not GPL) are available for decoding game videos? The requirements are simple: a relatively easy to use C API encoded files must be quite small there must be an application that converts videos from any format (whatever codec is installed on Windows or equivalent amount of internally decoded formats) decoding has to happen fairly quickly bonus points go to file formats that are popular / actively supported and developed

• Kinect losing tracked players with Beta2 SDK

  - by Eric B

  So i'm creating a game using the Beta2 SDK for Kinect. The issue i am having is that in the middle of gameplay if another person enters the Kinects FOV it stops tracking the player and will not track anyone else for several minutes. Same deal if the player leaves the FOV and reenters it. Here is what im using to detect players. void nui_SkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e) { int playersAlive = 0; // reset lists skeletons = new Dictionary<int, SkeletonData>(); //create a new list for skeletons menuSkeleton = new List<SkeletonData>(); initialPlayers = new Dictionary<float, SkeletonData>(); //create a new list for initialPlayers foreach (SkeletonData s in e.SkeletonFrame.Skeletons) //for each skeleton the kinect has detected { if (s.TrackingState == SkeletonTrackingState.Tracked) // players found { menuSkeleton.Add(s); if (initialized) // after initialization { skeletons.Add(s.TrackingID, s); } else // before initialization initialPlayers.Add(s.Joints[JointID.ShoulderCenter].Position.X, s); //if we are not initialized then add this player to the inital player list. playersAlive++; } } if (playersAlive == TOTAL_PLAYERS_ALLOWED) // If there is one player { if (!inMiniGame) // Before the game starts gameStart = DateTime.Now; // Reset initialization timer if (!initialized) // Before initialization // NOTE TO SELF I TOOK OUT && inMenu { InitializePlayers(); if (DateTime.Now.Subtract(gameStart).TotalMilliseconds > INITIALIZATION_WAIT_TIME) { initialized = true; // initialize timers from fixed starting time if (inMiniGame) //if the game has started { gamePause = gameStart; //TODO ERIC: Initialize any Timers Here } } } } } /// <summary> /// this function initializes the players adding them to a list /// and making one of the players the menu controller, for LIM we will need to change the code so that the /// game only recognizes and supports one player at a time /// variable names will need to be change as well. /// </summary> private void InitializePlayers() { List<float> initialPos = new List<float>(); // used to track starting positions players = new Dictionary<int, Player>(); foreach (float pos in initialPlayers.Keys) { initialPos.Add(pos); //add position of each inital player to list } float first = initialPos[0]; // left player first, right second Player player = new Player(initialPlayers[first].TrackingID, true); player.PlayerNumber = PLAYER_ONE; player.Skeleton = initialPlayers[first]; player.Specifics = new PlayerSpecifics(player.PlayerNumber); player.Specifics.PauseTimer = gameStart; players.Add(initialPlayers[first].TrackingID, player); menuController = initialPlayers[first].TrackingID; //menu controller is player 1 } This is a one player game. Also when the game starts Initialize is set to false, and gets set to true when i go from the games menu into the gameplay. So can anyone see any issues with this code block that would cause the kinect to lose players as they enter/exit the FOV? and not re-track them? Thank you for any help.

• Making a clone of a game legal?

  - by user782220

  My question is similar to a previous question. Consider the following clone of starcraft. Change the artwork, sound, music, change the names of units. However, leave the unit hitpoints unchanged, unit damage unchanged, unit movement speed unchanged, change ability names but not ability effects. Is that considered illegal? In other words is copying the unit hp, dmg, etc. considered illegal even if everything else is changed.

• Using multiplication and division with delta time

  - by tesselode

  Using delta time with addition and subtraction is easy. player.x += 100 * dt However, multiplication and division complicate things a bit. For example, let's say I want the player to double his speed every second. player.x = player.x * 2 * dt I can't do this because it'll slow down the player (unless delta time is really high). Division is the same way, except it'll speed things way up. How can I handle multiplication and division with delta time?

• Box2D platformer movement. Are joints a good idea?

  - by Romeo

  So i smashed my brains trying to make my character move. As i wanted later in the game to add explosions and bullets it wasn't a good idea to mess with the velocity and the forces/impulses didn't work as i expected so something stuck in my mind: Is it a good idea to put at his bottom a wheel(circle) which is invisible to the player that will do the movement by rotation? I will attach this to my main body with a revolute joint but i don't really know how to make the main body and wheel body to don't collide one with each other since funny things can happen. What is your oppinion?

• How should I determine direction from a phone's orientation & accelerometer?

  - by Manoj Kumar

  I have an Android application which moves a ball based on the orientation of the phone. I've been using the following code to extract the data - but how do I use it to determine what direction the ball should actually travel in? public void onSensorChanged(int sensor, float[] values) { // TODO Auto-generated method stub synchronized (this) { Log.d("HIIIII :- ", "onSensorChanged: " + sensor + ", x: " + values[0] + ", y: " + values[1] + ", z: " + values[2]); if (sensor == SensorManager.SENSOR_ORIENTATION) { System.out.println("Orientation X: " + values[0]); System.out.println("Orientation Y: " + values[1]); System.out.println("Orientation Z: " + values[2]); } if (sensor == SensorManager.SENSOR_ACCELEROMETER) { System.out.println("Accel X: " + values[0]); System.out.println("Accel Y: " + values[1]); System.out.println("Accel Z: " + values[2]); } } }

• how does the rectangle bounds (x,y,width,height) in libgdx work

  - by JG22

  I cant work out how to use the rectangle bounds in libgdx I am currently using the superJumper example and have 2or 3 examples with that are pause Bounds = new Rectangle(320 - 64, 480 - 64, 64, 64); this is the pause button in the top right corner resume Bounds = new Rectangle(160 - 96, 240, 192, 36); this is a rectangle resume button in the middle of the page in the menu that comes up when the pause button is pressed. basically my question is aimed at the 360 -64 and 160 -96 because I don't know why this is used I need to create a rectangle that covers the left side of the screen and the same on the right because I want to create a on screen buttons, I have already created the does for these buttons and I have managed to get them to work but I can move the rectangles to where I want. Thank you If you can help

• Updating the jump in game

  - by Luka Tiger

  I am making a Java game and I want my game to run the same on any FPS so I'm using time delta between each update. This is the update method of the Player: public void update(long timeDelta) { //speed is the movement speed of a player on X axis //timeDelta is expressed in nano seconds so I'm dividing it with 1000000000 to express it in seconds if (Input.keyDown(37)) this.velocityX -= speed * (timeDelta / 1000000000.0); if (Input.keyDown(39)) this.velocityX += speed * (timeDelta / 1000000000.0); if(Input.keyPressed(38)) { this.velocityY -= 6; } velocityY += g * (timeDelta/1000000000.0); //applying gravity move(velocityX, velocityY); /*this is method which moves a player according to velocityX and velocityY, and checking the collision */ this.velocityX = 0.0; } The strange thing is that when I have unlimited FPS (and update number) my player is jumping about 10 blocks. It jumps even higher when the FPS is increasing. If I limit FPS it is jumping 4 blocks. (BLOCK: 32x32) I have just realized that the problem is this: if(Input.keyPressed(38)) { this.velocityY -= 6; } I add -6 to velocityY which increases player's Y proportionally to the update number and not to the time. But I don't know how to fix this.

• Java enum pairs / "subenum" or what exactly?

  - by vemalsar

  I have an RPG-style Item class and I stored the type of the item in enum (itemType.sword). I want to store subtype too (itemSubtype.long), but I want to express the relation between two data type (sword can be long, short etc. but shield can't be long or short, only round, tower etc). I know this is wrong source code but similar what I want: enum type { sword; } //not valid code! enum swordSubtype extends type.sword { short, long } Question: How can I define this connection between two data type (or more exactly: two value of the data types), what is the most simple and standard way? Array-like data with all valid (itemType,itemSubtype) enum pairs or (itemType,itemSubtype[]) so more subtype for one type, it would be the best. OK but how can I construct this simplest way? Special enum with "subenum" set or second level enum or anything else if it does exists 2 dimensional "canBePairs" array, itemType and itemSubtype dimensions with all type and subtype and boolean elements, "true" means itemType (first dimension) and itemSubtype (second dimension) are okay, "false" means not okay Other better idea Thank you very much!

• Cliché monsters to populate a steampunk fantasy setting dwarven dungeon?

  - by Alexander Gladysh

  I'm looking for a list of cliché monsters for a steampunk computer game (assume one kind or another of casual rogue-like RPG), to populate lower levels of ancient dwarven-built dungeons. Dwarves are a technology/science race in the setting I am aiming for. The world is a low-magic one. I'm stuck after listing various mechanical golems, gigantic spiders (every dungeon must have some of them!), and maybe a mechanical barlog as a megaboss. What would player expect? What are the key cultural references for such setting? I know a couple of games with suitable steampunk dwarves, but none are detailed enough in the underworld monsters area. Please point me in the right direction. (If you have a single funny monster suggestion, please mention it in comments, not in answer. ;-) )

• A simple example of movement prediction

  - by Daniel

  I've seen lots of examples of theory about the reason for client-side prediction, but I'm having a hard time converting it into code. I was wondering if someone knows of some specific examples that share some of the code, or can share their knowledge to shed some light into my situation. I'm trying to run some tests to get a the movement going (smoothly) between multiple clients. I'm using mouse input to initiate movement. I'm using AS3 and C# on a local Player.IO server. Right now I'm trying to get the Client side working, as I'm only forwarding position info with the client. I have 2 timers, one is an onEnterFrame and the other is a 100ms Timer, and one on mouseClick listener. When I click anywhere with a mouse, I update my player class to give it a destination point On every enterFrame Event for the player, it moves towards the destination point At every 100ms it sends a message to the server with the position of where it should be in a 100ms. The distance traveled is calculated by taking the distance (in Pixels) that the player can travel in one second, and dividing it by the framerate for the onEnterFrame handler, and by the update frequency (1/0.100s) for the server update. For the other Players, the location is interpolated and animated on every frame based on the new location. Is this the right way of doing it?

• How to export a C++ class library to C# using a dll?

  - by SICGames2013

  In my previous revision game engine I deported major functions for the game editor for C#. Now, I'm beginning to revise the game engine with a static library. There's a already dynamic library created in C++ to use DLLEXPORT for C#. Just now I want to test out the newer functions and created a DLL file from C++. Because the DLL contains classes I was wondering how would I be able to use DLL Export. Would I do this: [DLLEXPORT("GameEngine.dll", EntryPoint="SomeClass", Conventional=_stdcall)] static extern void functionFromClass(); I have a feeling it's probably DLLImport and not DLLExport. I was wondering how would I go about this? Another way I was thinking was because I already have the DLL in C++ prepared already to go the C# Class Library. I could just keep the new engine as a lib, and link the lib with the old DLL C++ file. Wouldn't the EntryPoint be able to point to the class the function is in?

  I'm not "sure" which API (or language) I should use for a little 3D FPS game I'm gonna make although I don't have helpers lol. Anyway I'm ok with Java, C# and C++ but I need a good setup (easy to use) with the tools I need to make the game. I tried things like XNA but I want to check other options first because I don't like how it makes a installer and stuff, it's really annoying. I Need A API That Can Do These Things: 3D Rendering Input Sound And If It's Not Too Much To Ask Some Cool Shaders, Dynamic Lighting And A 3D Sound System Im "Ok" If I Have To Use Multiple APIs To Do This But Please Help Me!

• Extremely simple online multiplayer game

  - by Postscripter

  I am considering creating a simple multiplayer game, which focuses on physics and can accommodate up to 30 players per session. Very simple graphics, but smart physics (pushing, weight and gravity, balance) is required. After some research I found a good java script (framework ??) called box2d.js I found the demo to be excellent. this is is kind of physics am looking for in my game. Now, what other frameworks will I need? Node.js?? Prototype.js?? (btw, I found the latest versoin of protoype.js to be released in 2010...?? is this still supported? Should I avoid using it?) What bout HTML 5 and Canvas? would I need them? websockets? Am a beginner in web programming + game programming world. but I will learn fast, am computer science graduate. (but no much web expeience but know essentionals javascript, html, css..). I just need a guiding path to build my game. Thanks

• Why do consoles have so little memory compared to classic computers?

  - by jokoon

  I remember the Playstation having 2MB ram and 1MB graphic memory. The Playstation 3 now has only 256MB ram and 256MB graphic memory, and I'm sure that the day the console was released, even laptop's "standard" capacity was at least 1GB. So why do they put so little memory in their machines, while developers would benefit a lot by having more ? Or is the memory that much faster than desktops and thus more expensive ? Or is it not that much worth it for developers ? What are the Sony/XBox/Nintendo engineers thinking that seems to be the same reason ?
