• Is there a way to legally create a game mod?

  - by Rodrigo Guedes

  Some questions about it: If I create a funny version of a copyrighted game and sell it (crediting the original developers) would it be considered a parody or would I need to pay royalties? If I create a game mod for my own personal use would it be legal? What if I gave it for free to a friend? Is there a general rule about it or it depends on the developer will? P.S.: I'm not talking about cloning games like this question. It's all about a game clearly based on another. Something like "GTA Gotham City" ;) EDIT: This picture that I found over the internet illustrate what I'm talking about: Just in case I was not clear: I never created a mod game. I was just wondering if it would be legally possible before trying to do it. I'm not apologizing piracy. I pay dearly for my games (you guys have no idea how expensive games are in Brazil due to taxes). Once more I say that the question is not about cloning. Cloning is copy something and try to make your version look like a brand new product. Mods are intended to make reference to one or more of its source. I'm not sure if it can be done legally (if I knew I wasn't asking) but I'm sure this question is not a duplicate. Even so, I trust in the moderators and if they close my question I will not be offended - at least I had an opportunity to explain myself and got 1 good answer (by the time I write this, maybe some more will be given later).

• Looking for a simple web interface with subversion support and ticket /issue tracker [closed]

  - by Stefan Andre Brannfjell

  I am working on a small project and we have a few programmers on the job. We are using subversion to commit updates and keep all developers up to date on their workstations. However, we have yet to find a suitable web interface to use for it. I have tried redmine, but that installation progress was extremely bothersome and advanced. Once I got it to work I found out that it was slow and did not meet my expectations. As well as it seems a bit complex for our needs. I would prefer to find a solution that supports lighttpd web server, however that seem to be very hard to come by, those I have found seem to only have apache support. Functionality i wish for the website: - login to an svn account - view svn logs - view & create issues, todo list etc - view svn difference Do you have any open source recommendations that I can try out? I will appreciate any kind of reply. :) Edit: I wish to host the website on our own servers.

• Tool for creating complex paths?

  - by TerryB

  I want to create some fairly complex predefined paths for my AI sprites to follow. I'll need to use curves, splines etc to get the effect I want. Is there a drawing tool out there that will allow me to draw such curves, "mesh" them by placing lots of points along them at some defined density and then output the coordinates of all of those points for me? I could write this tool myself but hopefully one of the drawing packages can do this? Cheers!

• What does SetTextureStage(0, D3DTSS_COLORARG2, 0) in DirectX mean?

  - by Vite Falcon

  I'm trying to convert some DirectX code to Ogre3D and was wondering what the following translates to: pDev->SetTextureStage(0, D3DTSS_TEXCOORDINDEX, 0) pDev->SetTextureStage(0, D3DTSS_COLORARG1, D3DTA_TEXTURE) pDev->SetTextureStage(0, D3DTSS_COLOROP, D3DTOP_MODULATE) pDev->SetTextureStage(0, D3DTSS_COLORARG2, 0) What is the modulation operation happening here? Is the texture getting modulated with the background? Or is it getting zeroed? I've tried searching for what this means and unfortunately I haven't come across anything meaningful. Any help to shed light on this matter will be much appreciated.

• I'm using OpenAL, trying to load a .ogg file and having .dll troubles

  - by Brendan Webster

  I'm using OpenAL for my game's music, and it loads .wav files by default, but to load in Ogg files I had to download and setup a few .dlls and lib files. I have fixed all errors with dlls except for this: I need vorbis.dll, and it says it's missing vorbis_window. I just can't find the dll anywhere online that includes the vorbis_window, anyone have suggestions on how I should fix this problem with my dll?

• Calculating 2D (screen) coordinates from 3D positions in XNA 4.0

  - by NDraskovic

  I have a program that draws some items to the scene by loading their positions from a file. Now I want to place a Ray on the same location where the items are drawn. So my question is how can I calculate the position of the ray (it's 2D components) by using 3D coordinates of each particular item? The items don't move anywhere, so once they are placed they stay until the end of the programs execution. Thanks.

• Parent variable inheritance methods Unity3D/C#

  - by Timothy Williams

  I'm creating a system where there is a base "Hero" class and each hero inherits from that with their own stats and abilities. What I'm wondering is, how could I call a variable from one of the child scripts in the parent script (something like maxMP = MP) or call a function in a parent class that is specified in each child class (in the parent update is alarms() in the child classes alarms() is specified to do something.) Is this possible at all? Or not? Thanks.

• Objective C - Aggro with Images

  - by Will

  I have three UIImageViews. enemy1, enemy1AggroBox and mainSprite. What I want to do is when mainSprite and enemy1AggroBox interect, I want enemy1 to start moving towards mainSprite. Basically creating aggro for a game. if(CGRectIntersectsRect(mainSprite.frame, enemy1AggroBox.frame)){ //Code here// } My plan would be to call this method in viewDidLoad. I'm not using any sort of framework like cocos2d or OpenGLES. If you need to see any more code just ask.

• How can I factor momentum into my space sim?

  - by Josh Petite

  I am trying my hand at creating a simple 2d physics engine right now, and I'm running into some problems figuring out how to incorporate momentum into movement of a spaceship. If I am moving in a given direction at a certain velocity, I am able to currently update the position of my ship easily (Position += Direction * Velocity). However, if the ship rotates at all, and I recalculate the direction (based on the new angle the ship is facing), and accelerate in that direction, how can I take momentum into account to alter the "line" that the ship travels? Currently the ship changes direction instantaneously and continues at its current velocity in that new direction when I press the thrust button. I want it to be a more gradual turning motion so as to give the impression that the ship itself has some mass. If there is already a nice post on this topic I apologize, but nothing came up in my searches. Let me know if any more information is needed, but I'm hoping someone can easily tell me how I can throw mass * velocity into my game loop update.

• Checking is sides of cubes are solid

  - by Christian Frantz

  In relation to this question: http://gamedev.stackexchange.com/a/28524/31664 And a question I asked earlier: Creating a DrawableGameComponent And also because my internet is too slow to get on chat. I'm wondering how to check if the sides of a cube are solid. I've created 12 methods, each one creating indices and vertices for sides of a cube. Now when I use these methods, the cube creates how it should. All 6 sides show up and its like I didnt change a thing. How can use if statements to check if the side of a cube is solid? The pseudocode from the question above shows this: if(!isSolidAt(x+1,y,z)) verticesToDraw += AddXPlusFace(x,y,z) But in my case is would be: if(!sideIsSolid) SetUpFrontFaceIndices(); My method simply takes these index and vertex values and adds them to a list indicesToDraw and verticesToDraw, as shown in the answer above

• Integration error in high velocity

  - by Elektito

  I've implemented a simple simulation of two planets (simple 2D disks really) in which the only force is gravity and there is also collision detection/response (collisions are completely elastic). I can launch one planet into orbit of the other just fine. The collision detection code though does not work so well. I noticed that when one planet hits the other in a free fall it speeds backward and goes much higher than its original position. Some poking around convinced me that the simplistic Euler integration is causing the error. Consider this case. One object has a mass of 1kg and the other has a mass equal to earth. Say the object is 10 meters above ground. Assume that our dt (delta t) is 1 second. The object goes to the height of 9 meters at the end of the first iteration, 7 at the end of the second, 4 at the end of the third and 0 at the end of the fourth iteration. At this points it hits the ground and bounces back with the speed of 10 meters per second. The problem is with dt=1, on the first iteration it bounces back to a height of 10. It takes several more steps to make the object change its course. So my question is, what integration method can I use which fixes this problem. Should I split dt to smaller pieces when velocity is high? Or should I use another method altogether? What method do you suggest? EDIT: You can see the source code here at github:https://github.com/elektito/diskworld/

• Moving camera, or camera with discrete "screens"?

  - by Jacob Millward

  I'm making a game with a friend, but having trouble deciding on a camera style. The basic idea for the game, is having a randomly generated 2-dimensional world, with settlements in it. These settlements would have access to different resources, and it would be the job of the player to create bridges and ladders and links between these villages so they can trade. The player would advance personally by getting better gear, fighting monsters and looking for materials in the world, in order to craft and trade them at the settlements. My friend wants to use an old-style camera, where the world is split into a discrete number of screens that the player moves between. Similar to early Zelda dungeons, or Knytt Stories. This is opposite to me, as I want a standard camera that follows the player around as I feel the split-screen style camera limits the game. Can anyone argue the case either way? We've hit a massive roadblock here and can't seem to get past it.

• What's the best game engine to use for my PC game project? [closed]

  - by user19860

  I'm in the planning phase of creating an action-rpg for the PC, and I'd like to create a League of Legends style look for the game (animated/cartoony). Any idea which engine best replicates this look? I ask because when I look at a lot of the UDk/Unreal games, they've all got the more realistic 3-D look that I'd like to avoid, so I was wondering if an alternate look was possible on that type of engine. Source SDK and Unity also look very interesting, I just don't know what types of visual capabilities these engines have. Thanks in advance.

• multithreading problem with Nvidia PhysX

  - by xcrypt

  I'm having a multithreading problem with Nvidia PhysX. the SDK requires that you call Simulate() (starts computing new physics positions within a new thread) and FetchResults(waits 'till the physics computations are done). Inbetween Simulate() and FetchResults() you may not 'compute new physics' It is proposed (in a sample) that we create a game loop as such: Logic (you may calculate physics here and other stuff) Render + Simulate() at start of Render call and FetchResults at end of Render() call However, this has given me various little errors that stack up: since you actually render the scene that was computed in the previous iteration in the game loop. I wonder if there's a way around this? I've been trying and trying, but I can't think of a solution...

• Multiple volumetric lights

  - by notabene

  I recently read this GPU GEMS 3 article Volumetric Light Scattering as a Post-Process. I like the idea to add volumetric light property to realtime render i'm working on. Question is will it work for multiple lights? Our renderer uses one render pass per light and uses additive blending to sum incoming light. I'm mostly convinced that it have to work nice. Do you agree? Maybe there can be problem where light rays crosses each other.

• Why does the location of my vehicle spawner change when I open a matinee?

  - by Gareth Jones

  I'm doing work with InterActors and vehicle spawners in Unreal Tournament 3's editor, and have it set up like so: (The Walkway its on is the InterActor) However if I go in Kemsit and open the matinee that handles the InterActor, this happens: It does look to me like the editor is moving it out of the way so I can see the InterActor (which would be very clever) because only the image of the vehicle moves, not the gizmo, nor does the vehicle spawn in that location in game. Is this the case?

• importing animations in Blender, weird rotations/locations

  - by user975135

  This is for the Blender 2.6 API. There are two problems: 1. When I import a single animation frame from my animation file to Blender, all bones look fine. But when I import multiple (all of the frames), just the first one looks right, seems like newer frames are affected by older ones, so you get slightly off positions/rotations. This is true when both assigning PoseBone.matrix and PoseBone.matrix_basis. bone_index = 0 # for each frame: for frame_index in range(frame_count): # for each pose bone: add a key for bone_name in bone_names: # "bone_names" - a list of bone names I got earlier pose.bones[bone_name].matrix = animation_matrices[frame_index][bone_index] # "animation_matrices" - a nested list of matrices generated from reading a file # create the 'keys' for the Action from the poses pose.bones[bone_name].keyframe_insert('location', frame = frame_index+1) pose.bones[bone_name].keyframe_insert('rotation_euler', frame = frame_index+1) pose.bones[bone_name].keyframe_insert('scale', frame = frame_index+1) bone_index += 1 bone_index = 0 Again, it seems like previous frames are affecting latter ones, because if I import a single frame from the middle of the animation, it looks fine. 2. I can't assign armature-space animation matrices read from a file to a skeleton with hierarchy (parenting). In Blender 2.4 you could just assign them to PoseBone.poseMatrix and bones would deform perfectly whether the bones had a hierarchy or none at all. In Blender 2.6, there's PoseBone.matrix_basis and PoseBone.matrix. While matrix_basis is relative to parent bone, matrix isn't, the API says it's in object space. So it should have worked, but doesn't. So I guess we need to calculate a local space matrix from our armature-space animation matrices from the files. So I tried multiplying it ( PoseBone.matrix ) with PoseBone.parent.matrix.inverted() in both possible orders with no luck, still weird deformations.

• What is the best way to check if there is overlap between player and static, non-collidable items in bullet physic engine

  - by tigrou

  I'd like to add non collidable objects (eg: power ups, items, ...) in a game world using Bullet Physics Engine and to know if there is collision between player and them. Some info : there is a lot of items ( 1000), all are box shapes and they don't overlap. Here is things i have tried : btDbvt* bvtItems = new btDbvt(); //btDbvt is a hierachical AABB tree, used by Bullet foreach(var item ...) { btDbvtVolume volume = ... //compute item AABB; bvtItems->insert(volume, (void*)someExtraData); } Then, to find collisions between items and player : playerRigidBody->getAabb(min, max); btDbvtVolume playervolume = ... //compute player AABB bvtItems->collideTV(bvtItems->m_root, playervolume, *someCollisionHandler); This works fairly well (and its very fast), however, there is a problem : it only check items AABB against player AABB. That loss of precision is acceptable for items but not for player which is not a box. It would actually need another check to make sure player really collide with item but i don't know how to do this in Bullet. It would have been nice to have a function like this : playerRigidBody->checkCollisionWithAABB(); After doing trying that, I discovered that a btGhostObject exist and seems to have been made for that. I changed my code like this : foreach(var item...) { btCollisionObject* ghostObject = new btGhostObject(); ghostObject->setCollisionShape(boxShape); ghostObject->setCollisionFlags(ghostObject->getCollisionFlags() | btCollisionObject::CF_NO_CONTACT_RESPONSE); startTransform.setOrigin(...); //item position ghostObject->setWorldTransform(startTransform); dynamicsWorld->addCollisionObject(ghostObject, btBroadphaseProxy::SensorTrigger, btBroadphaseProxy:: CharacterFilter); } It also works ok, but there is a huge fps drop (almost ten times slower) which is not acceptable. Maybe there is something missing (forget set a flag) and Bullet is doing extra job for nothing or maybe all that ghostObjects are polluting broad phase and ghostObject is not the right thing for that. Any help would be appreciated.

• Isometric Movement in Javascript In the DOM

  - by deep

  I am creating a game using Javascript. I am not using the HTML5 Canvas Element. The game requires both side view controlles, and Isometric controls, hence the movementMode variable. I have got the specific angles, but I am stuck on an aspect of this. https://chillibyte.makes.org/thimble/movement function draw() { if (keyPressed) { if (whichKey == keys.left) { move(-1,0) } if (whichKey == keys.right) { move(1,0) } if (whichKey == keys.up) { move(0,-1) } if (whichKey == keys.down) { move(0,1) } } } This gives normal up, down , left, and right. i want to refactor this so that i can plugin two variables into the move() function, which will give the movement wanted. Now for the trig. /| / | / | y / | /a___| x Take This Right angled Triangle. given that x is 1, y must be equal to tan(a) That Seems right. However, when I do Math.tan(45), i get a number similar to 1.601. Why? To Sum up this question. I have a function, and i need a function which will converts an angle to a value, which will tell me the number of pixels that i need to go up by, if i only go across 1. Is it Math.tan that i want? or is it something else?

• How do I get the source code from a Google Code game project?

  - by BluFire

  I'm trying to get the Hedgewars source code. When I went to the downloads tab, it doesn't specify which is the actual game. I tried downloading it using the SVN Checkout on Tortoise, but it seems like it doesn't work on the browse section of Source. (Hgproject_filesAndroid_buildSDL-android-project) I then proceeded to the wiki but I got stuck at step two because I don't know anything about Mercurial. Some other things I don't know from the wiki is "FreePascal" "Android NDK" and "Tar" files. They are new to me so I am really confused. So my question is, how can I download the source code from Hedge Wars for Android without having to browse the source code inside the source tab?

• Importing a windows project into android using cocos2d-x

  - by Ef Es

  What I am trying to do today is to import a full project to Android, but no tutorials are available for that that I have seen. My approach was to create a new android project, copy all the classes and resources in the folders and calling ./build_native.sh but I get an error because most of the files are not being included in the project. I tried opening the Android.mk and I can see why "LOCAL_SRC_FILES := AppDelegate.cpp \ HelloWorldScene.cpp" are the only files linked. Should I manually modify the make file or can it be automated by some way I don't know? Thank you. UPDATE: I manually added all files and headers to the make file and I get errors linking Box2D or cocosdenshion libraries.

• Need ideas for an algorithm to draw irregular blotchy shapes

  - by Yttermayn

  I'm looking to draw irregular shapes on an x,y grid, and I'd like to come up with a simple, fast method if possible. My only idea so far is to draw a bunch of circles of random sizes very near each other, but at a random distance apart from a more or less central coordinate, then fill in any blank spaces. I realize this is a clunky, inelegant method, hopefully it will give you a rough idea of the kinds of rounded, random blotchy shapesI'm shooting for. Please suggest methods to accomplish this, I'm not so much interested in code. I can noodle that part out myself. Thanks!

• How can I simulate objects floating on water without a physics engine?

  - by user1075940

  In my game the water movement is done in a shader using Gerstner equations. The water movement looks realistic enough for a school project but I encounter serious problem when I wanted to do sailing on waves (similar to this). I managed to do collision with land by calculating quad's vertices and normals beneath ship, however same method can not be applied to water because XZ are displaced and Y is calculated in a shader :( How to approach this problem ? Is it possible to retrieve transformed grid from shader? Unfortunately no external physics libraries can be used.

• What is a currently a good game stack for simple Javascript 2D multiplatform game?

  - by JacobusR

  I'm looking for advice from someone can help me avoid common pitfalls in developing light weight, quick-to-market games. Yeah, I've heard of Google ;-), but a trip down Google lane does not beat solid experience from someone who has been down this path. I'm looking for advice from someone who works alone, or in a small team, and has developed some 2D games for mobile. My game ideas don't require intensive graphics, just simple arcade style glyphs and collision detection. My experience is mostly with Scala, Java and web technologies (Javascript, CSS, SVG, HTML, etc). My question is: Is there a nice stack that someone can suggest that will be a good fit for my skillset? I'm considering Javascript for simple 2D shooter games with simple multiplayer games being supported with a Scala server-side written on Spray. Is this silly? Should I rather look into things such as Unity 3D, and use it in 2D mode? For the actual game engine, something like the Sparrow Framework would be great, but it needs to be multiplatform.

• What program should i use for Ludum Dare?

  - by mFontoura

  I want to participate for the first time on Ludum Dare, but i'm not confortable yet with a language to pick one for making a game on a weekend. So i was looking for a program 'gamemaker' style, just to make something for LD. I was going for Construct 2, but i use Linux and they don't have a linux version. So the alternative i use is Stencyl, witch is great and probably is what i'm going to use. However, i wanted to know if there is something similar and better for Linux. Also, if i get a computer with Win8, is it worth the trouble for Construct 2?
