• HP Envy Beats Edition can play CDs, but not DVDs

  - by Grayson

  After a fresh install, and various other tests (troubleshooting), I have concluded that my laptop (an HP Envy 14 - Beats Edtion) will not play DVDs, however it will play CDs. When I first got the laptop, up until recently it played DVDs perfectly, I doubt there is a hardware issue sees as it loads the DVDs and can view the files in them, but not play them, as well as read and work with CDs perfectly. Was there an update or something of the like that may have caused this? If so, is there a fix? I typically use this laptop 's HDMI out with my TV as a DVD player... so it would be very beneficial if there was a solution to this problem. There was a similar issue with the touchpad that there was a fix for... so I'm hoping that this is something similar

• How to solve problems with movement in simple tile based multiplayer game?

  - by Murlo

  I'm making a simple tile based 2D multiplayer game in JavaScript using socket.io where you can move one tile every 200 ms. The two solutions I've tried are as follows: The client sends "walk one tile north" every 200 ms. Problem: People can easily hack the client to send the action more often. The client sends "walking north" and "stopped walking". Problem: Sometimes the player moves extra steps when "stopped walking" doesn't arrive in time. Do you know a way around these problems or is there a better way to do it? EDIT: Regarding the first solution I've tried adding validation on the server to check if it has been 200 ms since last movement. The problem is that latency still encourages people just to spam the action as much as possible, giving them an unfair advantage.

• How can i get almost pixel perfect collision detection in a multiplayer game?

  - by Freddy

  I'm currently working on a multiplayer game for iPhone. The problem i have, as with all multiplayer games, is that the other user will always see everything at a non-constant delay. The game I'm making need to have a almost pixel perfect collision detection, but 1 or 2 pixels off is not that big of a deal. How can I possibly get this working? I guess I could just set local player to also be at X ms delay. However this will probably just be worse and feel sloppy when the user input. I know this problem is probably something network programmers deal with everyday and I would be glad if someone could give me a possible solution for this.

• Trying to create a sphere in UDK on which I can stand

  - by Dave

  Trying to build a globe in UDK, but when I do (create a sphere), my player falls straight through it. How do I make a sphere that I can walk on? Every other shape (cube, cone...etc) work just fine. -- Edit: Specifically, I want to build a CSG/Brush sphere, not a mesh sphere. It appears to work just fine if I set the "sphere exptrapolation" to 1 or 2, but if I bump it up to 3 or higher, I fall right through. I literally created 2 spheres next to each other, one set at "2" and one at "3" - I can walk from the top of the "2" sphere and jump onto the "3" sphere, but I fall right through it.

• Is there a size limit when using UICollectionView as tiled map for iOS game?

  - by Alexander Winn

  I'm working on a turn-based strategy game for iOS, (picture Civilization 2 as an example), and I'm considering using a UICollectionView as my game map. Each cell would be a tile, and I could use the "didSelectCell" method to handle player interaction with each tile. Here's my question: I know that UICollectionViewCells are dequeued and reused by the OS, so does that mean that the map could support an effectively infinitely-large map, so long as only a few cells are onscreen at a time? However many cells were onscreen would be held in memory, and obviously the data source would take up some memory, but would my offscreen map be limited to a certain size or could it be enormous so long as the number of cells visible at any one time wasn't too much for the device to handle? Basically, is there any memory weight to offscreen cells, or do only visible cells have any impact?

• Should actors in a game be responsible for drawing themselves?

  - by alex

  I am very new to game development, but not to programming. I am (again) playing around with a Pong type game using JavaScript's canvas element. I have created a Paddle object which has the following properties... width height x y colour I also have a Pong object which has properties such as... width height backgroundColour draw(). The draw() method currently is resetting the canvas and that is where a question came up. Should the Paddle object have a draw() method responsible for its drawing, or should the draw() of the Pong object be responsible for drawing its actors (I assume that is the correct term, please correct me if I'm incorrect). I figured that it would be advantagous for the Paddle to draw itself, as I instantiate two objects, Player and Enemy. If it were not in the Pong's draw(), I'd need to write similar code twice. What is the best practice here? Thanks.

• vlc issue with unity

  - by bob

  I'm using ubuntu 12.04 with unity 3d. I am having troubles to lock vlc (version: VLC media player 2.0.1 Twoflower (revision 2.0.1-0-gf432547)) to the left panel. It doesn't behave the same way other applications do. This is a fresh install from the repo, I didn't change any settings. Ubuntu 12.04 is also a fresh install. For example, (left) clicking on it doesn't bring it to front, but creates a new instance (this in particular is very annoying, if it gets behind another window, that happens to be maximized, there is no way to bring it back up). It also doesn't have a right arrow to say the number of instances there is. Any way around that ?

• 3D Collision help

  - by Taylor

  I'm having difficulties with my project. I'm quite new in XNA. Anyway, I'm trying to make 3D game and I'm already stuck on one basic thing. I have terrain made from a heightmap, and an avatar model. I want to set up some collisions for game so the player won't go through the ground. But I just don't know how to detect collisions for so complex an object. I could just make a simple box collision for my avatar, but what about the ground? I already implemented the JigLibX physics engine in my project and I know that I can make a collision map with heightmap, but I can't find any tutorials or help with this. So how can I set proper collision for complex objects? How can I detect heightmap collisions in JigLibX? Just some links to tutorials would be enough. Thanks in advance!

• Lag compensation of projectile shooting game

  - by Denis Ermolin

  I'm thinking about an algorithm for firing projectiles with lag compensation. Now I did find only one descent solution: Player hits fire button. Client sends input "fire". Client waits for server response. Server generates bullet then sends response to client. Client recieves response and finally fires projectile. Is this solution only "trueway"? I find it the only one that can be fair to all of the clients. Valve in this case, doesn't compensate lag from rocket shots. I am feeling that I will not compensate it, too. I think that with today's bandwidth I can close my eyes on this problem, because I don't see any solutions with fair logic. What do you think?

• 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?

• time issue in render libgdx [duplicate]

  - by jaysingh

  This question is an exact duplicate of: deWitters Game loop in libgdx(Android) pls. help how to implement this loop in render method next_game_tick and GetTickCount(); always contain same time value so player position not updated. @Override public void render() { float deltaTime = Gdx.graphics.getDeltaTime(); Update(deltaTime); Render(deltaTime); } const int TICKS_PER_SECOND = 50; const int SKIP_TICKS = 1000 / TICKS_PER_SECOND; const int MAX_FRAMESKIP = 10; DWORD next_game_tick = GetTickCount(); int loops; bool game_is_running = true; while( game_is_running ) { loops = 0; while( GetTickCount() > next_game_tick && loops < MAX_FRAMESKIP) { update_game(); next_game_tick += SKIP_TICKS; loops++; } display_game(); }

• Expiring timed actions a good idea?

  - by Bart van Heukelom

  We have an online game where players sometimes have to wait a while (say 30 minutes) before a process they intiated completes. This encourages them to come back later. An example of this is growing crops in Farmville or basically any action in the Sims Play4Free. Now, however, there is the idea to let these processes expire, so if the player doesn't 'reap' them in time (e.g. within 4 hours) they are aborted. I'm a bit sceptical about this. How will this make players come back more often? Is not the reward of reaping the process enough for that? Can we expect players to fit their daily schedule around our game, maybe even set the alarm clock at night? Won't this just cause players to give up on starting these processes in the first place? I realise this may be too subjective for this site, so I'll end with a concrete question: Do (m)any other online free-to-play games employ this technique?

• 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. ;-) )

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• Efficient way of detecting a touched object in a game?

  - by Pin

  Imagine a Sims-like 2D game for a touch based mobile phone where one can interact with virtually any object in the scene. How can I efficiently detect which object is being touched by the player? In my short experience, looping through all the visible objects in the scene and checking if they're touched has so far done the job, but when there may be many many moving objects in the screen that sounds kind of inefficient isn't it? Keeping the visible moving objects list can consume time in itself as one may have to loop through all of them each frame. Other solutions I've thought are: Spatial hashing. Divide the screen as a grid and place the visible objects in the corresponding bucket. Detection of the clicked object is fast but there's additional overhead for placing the objects in the correct bucket each frame. Maintaining a quad-tree. Moving objects have to be rearranged all the time, the previous solution looks better. What is usually done in this case?

• Cookie/money/point clicker game origin?

  - by gavenkoa

  I can't find myself origin of Clicker like games. It's where the goal is to gain points through clicks and acquired enhancement. There's only one strategy in the game - deciding how efficiently spend point on enhancement (see formulas). I've seen many games like this, but it seems that most don't have a home page or have an unknown publisher. Some well known games of this type: Candy Box Cookie Clicker Cow Clicker Who is first implemented this idea (not only clicking but with investment model - when player must decide what improve to faster gather points)?

• cannot add or remove programs using ubuntu software center (USC)in Kubuntu 12.04

  - by Suhail cholassery

  I am using Kubuntu 12.04,currently.Recently ,I updated my system with update manager and downloaded USC from muon software center which was pre-installed in this system. I could download a lot of softwares such as: -firefox -XBMC media center -VLC media player But when I tried to get some more softwares using USC, after rebooting there began the problem . It does not begin either downloading or instaling the program. When I tried to download the same program using muon software center it showed the following: Unable to obtain the package at this time Another application seems to be using the package system at this time. You must close all other package managers before you will be able to install or remove any packages. I am quite sure that have closed USC . I tried to remove USC, assuming that it caused the problem using muon software center but the result was same.Now I cannot add or remove any programs into my system & I don't know what to do . Please help me as soon as possible.

• Fast lighting with multiple lights

  - by codymanix

  How can I implement fast lighting with multiple lights? I don't want to restrain the player, he can place an unlimited number and possibly overlapping (point) lights into the level. The problem is that shaders which contain dynamic loops which would be necessary to calculate the lighting tend to be very slow. I had the idea that if it could be possible at compiletime to compile a shader n times where n is the number of lights. If the number n is known at compiletime, the loops can be unrolled automatically. Is this possible to generate n versions of the same shader with just a different number of lights? At runtime I could then decide which shader to use for which part of the level.

• Internal HDs that don't contain the OS aren't accessable unless I try to manually browse them

  - by Hrafn

  So I have 4 internal hard drives, one that contains the OS (Ubuntu 12.04), all ext4. After starting the computer up, and without having tried to access the drives (File manager, terminal etc) it seems like the drives haven't been mounted. If I go into the "Disks" utility I see that the disks haven't been mounted. Programs that try to access the HD's during startup throw an error. For example my music player can't find the library, my note taking software can't find the database etc. But after opening the drive in a file manager everything works. I've checked SMART on all the disks and everything is a ok. Any and all ideas would be appreciated.

• Where to start in creating a massive multiplayer 3D Java game [on hold]

  - by user1373771

  I am planning on creating a massive multiplayer world and I am wondering where to start. I am quite inexperienced in the field of Java but I have researched into it and learned that it is perhaps my best bet in creating this project is Java for the fact that it has a much easier learning curve than C++ to beginners and still capable of holding massive amounts of players at a time. My question is simple: Should I start the game by creating a single player prototype and introducing multiplayer later as I become more experienced or start with multiplayer before I am completely experienced in the field. Thanks for your help!

• Kernel panic when booting from USB

  - by maaartinus

  I downloaded ubuntu-11.04-desktop-amd64.iso and used Universal-USB-Installer-1.8.6.3.exe to format my USB stick und put the ISO on it. When I tried to install from it, I've got a kernel panic just like here, except for the version number (mine was 2.6.38-8-generic #42-ubuntu). My ISO image seems to work, as I installed it into a VMWare player without problems. Booting Linux from USB works surely too, as I did it some time ago with an older Ubuntu version. I can imagine things to try out, e.g., write the image again, try another version, pray, look for patches, etc. However, I'm looking for a time-efficient solution, something what most probably works. An advice of the sort "wait two weeks until it's surely fixed, then download again" is acceptable, I'm determined to switch to Linux, but it can wait a bit.

(I can't read the exact report atm because it has a chance of crashing my machine.) I have the 3D support box enabled. Here is my graphics card: Mobile Intel® GM45 Express Chipset x86/MMX/SSE2. Can anyone tell me to install drivers or something? I can't find mine anywhere!
