• Can I become a Game Designer? [on hold]

  - by user32721

  This is my first time posting something on a forum in 4 years. I am posting this because I want to adjust my expectations and goals regarding game design. I am in college in Morocco (Al Akhawayn university). just started my junior year. I am a communications major (school of humanities) and a gender studies minor. I want to become a video game designer. It is the only career that I am interested in. I have been playing ever since I was 5 and haven't stopped yet. Currently I don't have any noteworthy skills to become a designer. I don't know how to program (don't really have the patience for it) and I can't draw to save my life. I haven't tried visual software like MAYA or MAX so I can't comment on graphic design. So I basically want to know whether my current education is capable of helping me reach my goal. If not then should I take a master's in game design (in the U.S?) or switch my minor to computer science? I am sorry that this post is long! I look forward to hearing your advice!

• Turn-based Client-Server Card Game - Unicast (TCP) or Multicast (UDP)

  - by LDM91

  I am currently planning to make a card game project where the clients will communicate with the server in a turn-based and synchronous manner using messages sent over sockets. The problem I have is how to handle the following scenario: (Client takes it turn and sends its action to server) Client sends a message telling the server its move for the turn (e.g. plays the card 5 from its hand which needs to placed onto the table) Server receives messages and updates game state (server will hold all game state). Server iterates through a list of connected clients and sends a message to tell of them change in state Clients all refresh to display the state This is all based on using TCP, and looking at it now it seems a bit like the Observer pattern. The reason this seems to be an issue to me is this message doesn't seem to be point-to-point like the others as I want to send it to all the clients, and doesn't seem very efficient sending the same message in that way. I was thinking about using multicasting with UDP as then I could send the message to all the clients, however wouldn't this mean that the clients would in theory be able to message each other? There is of course the synchronous aspect as well, though this could be put on top of the UDP I guess. Basically, I would like to know what would be good practice as this project is really all about learning, and even though it won't be big enough to encounter performance issues from this I would like to consider them anyway. However, please note I am not interested in using message oriented middleware as a solution (I have experience with using MOM and I'm interested in considering other options excluding MOM if TCP sockets is a bad idea!).

• Professional Windows Phone 7 Game Development: Creating Games using XNA Game Studio 4

  - by Chris Williams

  In 24 short days*, my (along with the awesome George W. Clingerman) first book will be released:   Professional Windows Phone 7 Game Development: Creating Games using XNA Game Studio 4 (or as we like to call it, that damned 550 page monstrosity that nearly killed us) Weighing in at 552 pages and featuring a foreward by the legendary James Silva (Ska Studios, creator of The Dishwasher: Dead Samurai, The Dishwasher: Vampire Smile, I MAED A GAME W1TH Z0MB1ES 1NIT!!!1, and more...) this book gives thorough coverage of XNA 4.0 as it relates to Windows Phone 7. The book is written in a light, conversational tone, which means (unlike some books) you won't be compelled to gouge your eyes out with a rusty spork after reading the first few pages. At least, that’s the intent. If you do feel compelled to engage in some feats of eye-gouging sporkage, we (the authors of this book) would like to point out that we are not responsible and that seeking the help of a mental health professional might be advised. (We’re not qualified to dispense medical advice either.) The book is structured to introduce relevant material first, with code snippets and samples of how to use various phone features and XNA concepts, with helpful side notes along the way. After you've been exposed to a few chapters worth of concepts, you get the chance to bring them together by building a game that leverages those features. This book contains THREE (3!) complete games, including: Drive & Dodge (a racing game), Poker Dice (roll dice to make poker hand combinations) and Picture Puzzle (take a photo and turn it into a jigsaw puzzle.) Writing this book has been an incredible experience, and we hope reading it will be equally informative for all of you. We’re also happy to announce there will be a Kindle edition available, along with various other electronic media. Get your copy from Wiley.com, Amazon.com, Barnes & Noble, and anywhere else awesome books are sold. *more or less… some sites list the publication date as early march, but the official street date is 2/21/2011

• Which data structure you will use to for a witness list?

  - by mateen

  I'm making a game where the plot is a bank robbery. Lots of people witness that robbery. The game will load a list of suspects, while the players (witnesses) will have to identify the suspects of this robbery. The game should load a list of suspects to identify the one as quickly as possible. Admin can add/remove suspects in the lists and two or more lists of suspects can also be merged into one (to show it to the player). The question is which data structure will be suitable to develop the lists?

• 2D character controller in unity (trying to get old-school platformers back)

  - by Notbad

  This days I'm trying to create a 2D character controller with unity (using phisics). I'm fairly new to physic engines and it is really hard to get the control feel I'm looking for. I would be really happy if anyone could suggest solution for a problem I'm finding: This is my FixedUpdate right now: public void FixedUpdate() { Vector3 v=new Vector3(0,-10000*Time.fixedDeltaTime,0); _body.AddForce(v); v.y=0; if(state(MovementState.Left)) { v.x=-_walkSpeed*Time.fixedDeltaTime+v.x; if(Mathf.Abs(v.x)>_maxWalkSpeed) v.x=-_maxWalkSpeed; } else if(state(MovementState.Right)) { v.x= _walkSpeed*Time.fixedDeltaTime+v.x; if(Mathf.Abs(v.x)>_maxWalkSpeed) v.x=_maxWalkSpeed; } _body.velocity=v; Debug.Log("Velocity: "+_body.velocity); } I'm trying here to just move the rigid body applying a gravity and a linear force for left and right. I have setup a physic material that makes no bouncing and 0 friction when moving and 1 friction with stand still. The main problem is that I have colliders with slopes and the velocity changes from going up (slower) , going down the slope (faster) and walk on a straight collider (normal). How could this be fixed? As you see I'm applying allways same velocity for x axis. For the player I have it setup with a sphere at feet position that is the rigidbody I'm applying forces to. Any other tip that could make my life easier with this are welcomed :). P.D. While coming home I have noticed I could solve this applying a constant force parallel to the surface the player is walking, but don't know if it is best method.

• Design Pattern for Social Game Mission Mechanics

  - by Furkan ÇALISKAN

  When we want to design a mission sub-system like in the The Ville or Sims Social, what kind of design pattern / idea would fit the best? There may be relation between missions (first do this then this etc...) or not. What do you think sims social or the ville or any other social games is using for this? I'm looking for a best-practise method to contruct a mission framework for tha game. How the well-known game firms do this stuff for their large scale social facebook games? Giving missions to the players and wait players to complete them. when they finished the missions, providing a method to catch this mission complete events considering large user database by not using server-side not so much to prevent high-traffic / resource consumption. how should i design the database and server-client communication to achive this design condidering this trade-off.

• Game Maker Studio Gravity Problems

  - by Dusty

  I've started messing around with Game Maker Studio. The problem I'm having is trying to get a gravity code for orbiting. Here's how i did it in XNA foreach (GravItem Item in StarSystem.ActiveItems.OfType<GravItem>()) { if (this != Item) { Velocity += (10 * Vector2.Normalize(Item.Position - this.Position * (this.Mass * Item.Mass) / (Vector2.DistanceSquared(this.Position, Item.Position)) / (this.Mass)); } } Simple and works well, things or bit and everything is nice. but in Game maker i don't have the luxury of Vector2's or a For-each loop to loop threw all the objects that have a mass. I've tried a few different things but nothing seems to work distance = distance_to_object(obj_moon); //--Gravity hspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) vspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) thanks for the help

• Can and should a game design be patented?

  - by Christian

  I have an idea for a game that I want to develop and I feel is unique, and I'm wondering if I should patent it. I read on the web that games can be patented, but just because it can be done doesn't mean that it makes sense to do it. I actually don't really want patent it (it's expensive, a hassle and I don't believe in patenting of ideas... unless it's something truly revolutionary). However, I'm concerned a bigger company could come along, with more experienced game designers and developers and steal the idea.

• Collision Detection Game Design and Architecture

  - by Chompas

  I've reading some articles about collision detection. My question here is about ideas on the design for it. Baically I have a C++ game that has a main loop with entities with an update method. Based on keyboard input, these characters updates their positions. My question is not about how to detect collisions, it's about getting ideas in which is the best way to implement this. The game has a main character but also enemies that have to collide between them, so I'm not sure where to make all the iterations for checking collisions and if the right way is to check everything against everything. Thanks in advance.

• Deterministic replay in a modern game

  - by cloudraven

  I am doing a study in modern games graphics, and as part of the study it would be really helpful to be able to replay a sequence in the game multiple times. For example, recording a series of inputs to get the exact video sequences, but being able to replay them in different computers or different graphics configurations. I want to do this study with a couple of existing commercial games with sophisticated graphics (something released in the last 1 or 2 years if possible). I was thinking on hooking with detours or something similar, calls to time() or srand() to fix all pseudo-number generated results. It would be ideal to have a general solution that works with any game. Since admittedly that is pretty ambitious, I would be happy just having 2 or 3 games in which it is known that I can get deterministic output for a given input. In the end, I will be comparing video output, so I want to avoid noise generated by differences on each execution caused by non-determinism. Any sugestions?

• Facebook Game Rejected: "Your app icon must not overlap with content in your cover image"

  - by peterwilli

  Sorry if this isnt the right stackexchange site to ask this, it was really hard to determine. My FB game just recently got rejected for 2 reasons. The first I fixed nicely and is irrelevant but the second I just can't see to figure out what they mean and I was hoping someone else got the same issue and did know what they meant. These are the errors: You can ignore the error under "Banners" The web preview of my game looks like this now: All I know is that the rejection has something to do with the cover image, not the icons or the screenshots. Please let me know what to do to get approved. Thanks a lot!

• RTS game diplomacy heuristics

  - by kd304

  I'm reimplementing an old 4X space-rts game which has diplomacy options. The original was based on a relation scoring system (0..100) and a set of negotiation options (improve relations, alliance, declare war, etc.) The AI player usually had 3 options: yes, maybe and no; each adding or removing some amount to the relation score. How should the AI chose between the options? How does the diplomacy work in other games and how are they imlemented? Any good books/articles on the subject? (Googling the term diplomacy yields the game Diplomacy, which is unhelpful.)

• Time/duration handling in strategic game

  - by borg

  I'm considering developing a space opera game, having already done some game design. Technically, though, I'm coming from a business applications background. Hence I don't really know how I should handle time and duration. Let's state the matter clearly: what if something is bound to happen in 5 hours and on which other events depend. For example the arrival of some space ship in some system where some defense systems are present, hence a fight would start. Should I use some kind of scheduler (like Quartz in my java land) to trigger the corresponding event when due (I plan to use events for communication)? Something else?

  - by user2558

  In college me and my friends use to play cards all the time. I want to make a game for that. It's quite similar to hearts, a kind of modified hearts which we made up. I want to make a multiplayer game which could be played over the internet. Plus there should also be an option for computer to play if less players availiable at the time. I don't want to make a exe. I want to play in browser. How should I go about it.

• Game programming in C++ [closed]

  I am a new programmer. I know C++ quite well and I know C# very good. I'm really eager to learn how to program games well and I cant really find where to start learning from. I have never developed any graphics in C++ , only a crappy game with windows forms graphics. I'm really into game programming and hoping I can get employed in it in the future. I'd be glad to have some advice about this. Thanks in advance, Asaf

• cocos2d-x - object creation and management in game design

  - by Jason

  How do others keep track of everything going on in their games? I am working on a new game and I am quickly realizing everything that I need to keep track of. Example: Maybe a layerManager that keeps track of all the layers and what is happening for a particular scene. Maybe a sceneManager for sharing objects among scenes But then getting to game play itself, what if you have 100 objects on the screen each with its own state and happenings, there needs tobe a way to keep track of all of that. Drawing everything out is really helping me. Can anyone share with me how they go about object tracking/management? I am seeing a few different managers and then maybe even a parent object that manages the managers..is my thinking way off? Any design patterns that may be useful for me to read about? Update: doing some reading and maybe a Factory pattern might apply.

• Making game constants/tables available to game logic classes/routines in a modular manner

  - by Extrakun

  Suppose I have a game where there are several predefined constants and charts (a XP chart, cost of goods and so on). Those could be defined at runtime, or load from files at start-up. The question is how should those logic routines access the constants and charts? For example, I could try using global variables, but that cause all classes relying on the variables to be tightly coupled with them.

• Trying to develop a game with android for cracking glasses in different dimensions

  - by user46514

  I am trying to develop a game in android where I will have to punch a hole to get through the glass but not shatter the glass completely. The glass will show up in different forms of polygons and when a hole is created by a projectile, the rest of the polygon will still remain intact.Only a polygonal opening will get created at the point of impact with the projectile. I am new at game design in android but I was thinking that I would create a random polygon shape to show in the path and then at the point where the projectile hits it, I could create a glass polygon to create a splinter effect. The rest of the part of the glass that is randomly created at the point of impact, I could further splinter it into polygons flying at different angle. since I also need to capture the bits of glasses flying off and falling down with gravity. Is my solution the best efficient one at performance of threads or is there a better solution for this glass breaking effect. Thanks Dhiren

• Frames per Second and Updates per Second [on hold]

  - by matt murray

  So this is more a general resources question, as I am seeking knowledge on how best to conserve resources in a game (I am writing in Java, and please this is not a thread on what language I should write it in, I have already chosen Java) so that the updates and frames per second could be the highest they could be. In general I am just searching for any articles you may have, any personal experience, anything what so ever that could be of use to a pretty new Java game developer on the subject! Thanks in advance!

• Issues with shooting in a HTML5 platformer game

  - by fnx

  I'm coding a 2D sidescroller using only JavaScript and HTML5 canvas, and in my game I have two problems with shooting: 1) Player shoots continous stream of bullets. I want that player can shoot only a single bullet even though the shoot-button is being held down. 2) Also, I get an error "Uncaught TypeError: Cannot call method 'draw' of undefined" when all the bullets are removed. My shooting code goes like this: When player shoots, I do game.bullets.push(new Bullet(this, this.scale)); and after that: function Bullet(source, dir) { this.id = "bullet"; this.width = 10; this.height = 3; this.dir = dir; if (this.dir == 1) { this.x = source.x + source.width - 5; this.y = source.y + 16; } if (this.dir == -1) { this.x = source.x; this.y = source.y + 16; } } Bullet.prototype.update = function() { if (this.dir == 1) this.x += 8; if (this.dir == -1) this.x -= 8; for (var i in game.enemies) { checkCollisions(this, game.enemies[i]); } // Check if bullet leaves the viewport if (this.x < game.viewX * 32 || this.x > (game.viewX + game.tilesX) * 32) { removeFromList(game.bullets, this); } } Bullet.prototype.draw = function() { // bullet flipping uses orientation of the player var posX = game.player.scale == 1 ? this.x : (this.x + this.width) * -1; game.ctx.scale(game.player.scale, 1); game.ctx.drawImage(gameData.getGfx("bullet"), posX, this.y); } I handle removing with this function: function removeFromList(list, object) { for (i in list) { if (object == list[i]) { list.splice(i, 1); break; } } } And finally, in the main game loop I have this: for (var i in game.bullets) { game.bullets[i].update(); game.bullets[i].draw(); } I have tried adding if (game.bullets.length > 0) to the main game loop before the above draw&update calls, but I still get the same error.
