• 2D Pixel/sprite game in unity? [on hold]

  - by acidzombie24

  Hi I'm an absolute newbie in unity. In the past I was told unity is terrible for 2d games so I look away after looking at it for a few days. I don't remember if this was right before unity4 came out or after. I hear unity is fairly good at 2d now. I tried googling for tutorials but I'm doing it wrong. I could not find a good tetris or tic tac toe tutorial. What assets/tutorials do I want for a 2D game? Side question is what tutorials are good if I want to make a fire emblem/advance wars type game (HUD heavy grid base game)

• How do I choose the scaling factor of a 3D game world?

  - by concept3d

  I am making a 3D tank game prototype with some physics simulation, am using C++. One of the decisions I need to make is the scale of the game world in relation to reality. For example, I could consider 1 in-game unit of measurement to correspond to 1 meter in reality. This feels intuitive, but I feel like I might be missing something. I can think of the following as potential problems: 3D modelling program compatibility. (?) Numerical accuracy. (Does this matter?) Especially at large scales, how games like Battlefield have huge maps: How don't they lose numerical accuracy if they use 1:1 mapping with real world scale, since floating point representation tend to lose more precision with larger numbers (e.g. with ray casting, physics simulation)? Gameplay. I don't want the movement of units to feel slow or fast while using almost real world values like -9.8 m/s^2 for gravity. (This might be subjective.) Is it ok to scale up/down imported assets or it's best fit with a world with its original scale? Rendering performance. Are large meshes with the same vertex count slower to render? I'm wondering if I should split this into multiple questions...

• In a Tower defense game, how to do buffs/debuffs

  - by Gabe

  The question is at the very bottom. If you understand Buffs/Debuffs in tower defense games then you should skip the bulk of this question and go to the bottom (seperated with the long line) I plan on making an IPhone TD game. The fact that its an iPhone game isn't relevant but I am coding in Objective-c with Cocos2D. I am relatively inexperienced in the field of game design so I'm looking for some advice from someone experienced in this field. In tower defense, there are two things that are relevant to my question: towers/enemies (both have their own classes/children). They each have stats like hp, damage, speed, etc. I want to add buffs/defuffs, for instance: Towers A,B and C each have 15 base damage. Tower D would be a buff tower with no damage, a tower with an AOE(area of effect) aura that gives 10% damage to all towers in range. Tower E might slow enemies in its AOE, a debuff. Stuff like that. The same could go for enemies. Enemy A is a boss that has a slow aura that affects towers and slows their base attack speed or something along those lines. So the question is, what would be the most effective way to implement this? If it was just towers then I would just mess around with the tower classes, but since tower classes and enemy classes are both affected, should I make a buff class? TD games can consume quite a bit of memory with large amounts of creeps and towers, and buffs I feel like would also consume quit a bit... So I'm trying to be as effective as possible.

• Make Pong on android using OpenGL-ES

  - by brainydexter

  I am trying to make a simple pong game using opengl-es. I have checked out some of the tutorials/samples, but most of them are pre-dated to 2009. I am familiar with game programming, and consider pong to be the hello-world! Right now, I intend to make it using their supplied SDK (2.3), but eventually I want to make it in NDK, so I can port my other work to android. Would anyone have a good reference for a starting point ? Thanks

• LWJGL glRotatef() without rotating axes?

  - by Brandon oubiub

  Okay so, I noticed when you rotate around an axis, say you do this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); That will rotate things 90 degrees around the x-axis. However, it also sort of rotates the y and z axes as well. So now the y-axis is pointing in and out of the screen, instead of up and down. So when I try to do stuff like this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); glRotatef(whatever, 0.0f, 1.0f, 0.0f); glRotatef(whatever2, 0.0f, 0.0f, 1.0f); The rotations around the y and z-axes end up not how I want them. I was wondering if there is any way I can sort of rotate just the axes back to their initial position after using glRotatef(), without rotating the object back. Or something like that, just so that when I rotate around the y-axis, it rotates around a vertical axis.

• Problem with drawing textures in OpenGL ES

  - by droidmachine

  I'm developing a 2D game for Android and i'm using the framework which has been told in the book which named Beginning Android Games by Mario Zechner.So my framework is well designed and using OpenGL 1.1.It's similar to libgdx. When i put my textures adjacent each other in my 2d surface,there are some spaces size as 1 px.But this problem only occur on my tablet.There aren't a problem like this on my phone.It's like in this picture: What can be the problem?I can't fix it from one week.

• List of bounding boxes?

  - by Christian Frantz

  When I create a bounding box for each object in my chunk, would it be better to store them in a list? List<BoundingBox> cubeBoundingBox Or can I just use a single variable? BoundingBox cubeBoundingBox The bounding boxes will be used for all types of things so they will be moving around. In any case, I'd be adding it to a method that gets called 2500+ times for each chunk, so either I have a giant list of them or 2500+ individual boxes. Is there any advantage to using one or the other?

• Smarphone Apps. music, licenses and fees .. nightmare

  - by mm24

  I have recently asked a question about music in games like Guitar Hero. I have found that that in Europe (at least) if I do want to use a track composed by a musician member of a royalty collecting society I need to pay a flat fee to the society and not only to the member. So a "one-to-one" agreement is not valid and the society can come up to me and ask me for money for each download. Even if for FREE! This is a fee sheet list of the UK agency: for fee, see "Permanent download services" It is about 1,200 GBP for less than 22,000 copies and they DON'T specify anything more and they said me on the phone that I need to wait and see how many downloads I get before knowing the price. This is kind of crazy as If I give away the App for free I will have to PAY 1,200 GBP!! I am shocked and I feel very bad. One agency suggested me to use a fake name of the artist, but in this way is not fair to my collaborators as what they hope is that the App gets lots of downloads and in this way that other people will get to know about them and hopefully commission them more work. The other solution is to work only with non registered musicians. The question here to you is.. has anyone found a legal way to do use music from registered authors in a game?

• HLSL Pixel Shader that does palette swap

  - by derrace

  I have implemented a simple pixel shader which can replace a particular colour in a sprite with another colour. It looks something like this: sampler input : register(s0); float4 PixelShaderFunction(float2 coords: TEXCOORD0) : COLOR0 { float4 colour = tex2D(input, coords); if(colour.r == sourceColours[0].r && colour.g == sourceColours[0].g && colour.b == sourceColours[0].b) return targetColours[0]; return colour; } What I would like to do is have the function take in 2 textures, a default table, and a lookup table (both same dimensions). Grab the current pixel, and find the location XY (coords) of the matching RGB in the default table, and then substitute it with the colour found in the lookup table at XY. I have figured how to pass the Textures from C# into the function, but I am not sure how to find the coords in the default table by matching the colour. Could someone kindly assist? Thanks in advance.

• How to make an arc'd, but not mario-like jump in python, pygame [duplicate]

  - by PythonInProgress

  This question already has an answer here: Arc'd jumping method? 2 answers Analysis of Mario game Physics [closed] 6 answers I have looked at many, many questions similar to this, and cannot find a simple answer that includes the needed code. What i am trying to do is raise the y value of a square for a certain amount of time, then raise it a bit more, then a bit more, then lower it twice. I cant figure out how to use acceleration/friction, and might want to do that too. P.S. - can someone tell me if i should post this on stackoverflow or not? Thanks all! Edit: What i am looking for is not mario-like physics, but a simple equation that can be used to increase then decrease height over the time over a few seconds.

• Should I use procedural animation?

  - by user712092

  I have started to make a fantasy 3d fps swordplay game and I want to add animations. I don't want to animate everything by hand because it would take a lot of time, so I decided to use procedural animation. I would certainly use IK (starting with simple reaching an object with hand ...). I also assume procedural generation of animations will make less animations to do by hand (I can blend animations ...). I want also to have a planner for animation which would simplify complex animations; those which can be split to a sequence - run and then jump, jump and then roll - or which are separable - legs running and torso swinging with sword -. I want for example a character to chop a head of a big troll. If troll crouches character would just chop his head off, if it is standing he would climb on a troll. I know that I would have to describe the state ("troll is low", "troll is high", "chop troll head" ..) which would imply what regions animation will be in (if there is a gap between them character would jump), which would imply what places character can have some of legs and hands or would choose an predefined animation. My main goal is simplicity of coding, but I want my game to be looking cool also. Is it worthy to use procedural animation or does it make more troubles that it solves? (there can be lot of twiddling ...) I am using Blender Game Engine (therefore Python for scripting, and Bullet Physics).

• Simulating an object floating on water

  - by Aaron M

  I'm working on a top down fishing game. I want to implement some physics and collision detection regarding the boat moving around the lake. I would like for be able to implement thrust from either the main motor or trolling motor, the effect of wind on the object, and the drag of the water on the object. I've been looking at the farseer physics engine, but not having any experience using a physics engine, I am not quite sure that farseer is suitable for this type of thing(Most of the demos seem to be the application of gravity to a vertical top/down type model). Would the farseer engine be suitable? or would a different engine be more suitable?

• Most efficient way to send images across processes

  - by Heinrich Ulbricht

  Goal Pass images generated by one process efficiently and at very high speed to another process. The two processes run on the same machine and on the same desktop. The operating system may be WinXP, Vista and Win7. Detailled description The first process is solely for controlling the communication with a device which produces the images. These images are about 500x300px in size and may be updated up to several hundred times per second. The second process needs these images to display them. The first process uses a third party API to paint the images from the device to a HDC. This HDC has to be provided by me. Note: There is already a connection open between the two processes. They are communicating via anonymous pipes and share memory mapped file views. Thoughts How would I achieve this goal with as little work as possible? And I mean both work for me and the computer. I am using Delphi, so maybe there is some component available for doing this? I think I could always paint to any image component's HDC, save the content to memory stream, copy the contents via the memory mapped file, unpack it on the other side and paint it there to the destination HDC. I also read about a IPicture interface which can be used to marshall images. What are your ideas? I appreciate every thought on this!

• What is a technique for 2D ray-box intersection that is suitable for old console hardware?

  - by DJCouchyCouch

  I'm working on a Sega Genesis homebrew game (it has a 7mhz 68000 CPU). I'm looking for a way to find the intersection between a particle sprite and a background tile. Particles are represented as a point with a movement vector. Background tiles are 8 x 8 pixels, with an (X,Y) position that is always located at a multiple of 8. So, really, I need to find the intersection point for a ray-box collision; I need to find out where along the edge of the tile the ray/particle hits. I have these two hard constraints: I'm working with pixel locations (integers). Floating point is too expensive. It doesn't have to be super exact, just close enough. Multiplications, divisions, dot products, et cetera, are incredibly expensive and are to be avoided. So I'm looking for an efficient algorithm that would fit those constraints. Any ideas? I'm writing it in C, so that would work, but assembly should be good as well.

• How can I import models from Blender into jMonkeyEngine?

  - by Nathan Sabruka

  I have some blender model files (Blender version 2.6) which I would like to use with the jMonkeyEngine SDK. However, when I use Blender's native .obj exporter, I can't import it in jMonkeyEngine (the model simply fails to import or looks messed up). I've tried importing .obj files or .blend files directly into the jMonkeyEngine SDK to no avail. I've also tried to use various OGRE exporters to export .scene and .material files, but only the .scene file is created. Is there a simple way to simply export files from Blender into the jMonkeyEngine SDK? EDIT: I seem to have found something in Blender. When I go under addons, there's a warning in the OGRE exporter; "'.mesh' output requires OgreCommandLineTools". However, I have already installed those tools under the C drive. Has anyone else encountered this issue?

• Hero/Character sprite size in comparison to tile size?

  - by Kid

  So I'm making this simple platformer where the Hero is 16x16 in size, but also, the tile size is 16x16. Which sounds fine right? But my game window/world is 800x416, which makes the Hero is really really tiny in comparison. This really surprised me, but given Ive never made a platformer before it is also a new discovery. Is there a rule set for scale in platformer games? I'd like to have my game window remain the size it is (800x416), cause the game involves large levels. But how big should my hero be? I hope I was clear with the question, and I appreciate any insight. Thanks

• 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

• Effective way to check if an Entity/Player enters a region/trigger

  - by Chris

  I was wondering how multiplayer games detect if you enter a special region. Let's assume there is a huge map that is so big that simply checking it would become a huge performance issue. I've seen bukkit (a modding API for Minecraft servers) firing an Event on every single move. I don't think that larger games do the same because even if you have only a few coordinates you are interested in, you have to loop through a few trigger zone to see if the player is inside your region - for every player. This seems like an extremely CPU-intense operation to me even though I've never developed something like that. Is there a special algorithm that is used by larger games to accomplish this? The only thing I could imagine is to split up the world into multiple parts and to register the event not on the movement itself but on all the parts that are covered by your area and only check for areas that are registered in the current part. And another thing I would like to know: How could you detect when someone must have entered a trigger but you never saw him directly in it since his client only sent you an move packet shortly before entering and after leaving the trigger area. Drawing a line and calculate all colliding parts seems rather CPU intensive if you have to perform it every time.

• Texturing a mesh generated from voxel data

  - by Minja

  I have implemented the Marching Cubes algorithm to display an isosurface based on voxel data. Currently, it is displayed with triplanar texturing. I'm working with unity, so I have a material with the triplanar shader attached. Now, the whole isosurface is rendered using this material. And thats my problem: I want the texture to represent the voxel data. I'm storing a material value for every point in the grid, and based on this value, I want the texture of the isosurface to change. Sadly, I have no clue how to do this. So if the voxel is sand, I want sand to be displayed; if it's stone, then there should be stone. Right now, everything is displayed as sand. Thanks in advance!

  This is a followup to this question. To sum: I'm implementing an AI contest site, where each user may submit several AI implementations for different games. Think about Google AI Challenge but instead of just having a big event once a year, I would like it more on a league fashion, with all virtual players playing with each other every some close period of time. I want to support as many programming languages as possible. I've seen that contest sites (like codeforces) ask you to submit a source code and interact through stdin and stdout. The first question is: what is the best way of supporting multiple languages? As I see it, I can either ask people to upload some binary/script, and interact either through stdin/*stdout*, or sockets, or the file system; or ask people to submit source code, and wrap it with whatever is necessary for the interaction. I would like to skip the need to compile the code by myself (in the server, I mean), but I am willing to do it if its the "best" choice. I need to comunicate virtual players with each other, or even better, with some intermediary arbiter. The second question is regarding security. If I'm going to be running user code in my server, I want to ensure strict security conditions, like no file system access, no networking, etc. Otherwise it would be a safe heaven for hackers. I will be implementing the engine/arbiter in .NET. I would like to support at least C#, C++, Java and Python for the user's implementations. I'm willing to write interfaces for each of these languages to simplify the user interaction with the system. Thanks in advance.

• Automated texture mapping

  - by brandon

  I have a set of seamless tiling textures. I want to be able to take an arbitrary model and create a UV map with these properties: No stretching (all textures tile appropriately so there is no stretching and sheering of the texture) The textures display on the correct axis relative to the model it's mapping to (if you look at the example, you can see some of the letters on the front are tilted, the y axis of the texture should be matching up with the y axis of the object. Some other faces have upside down letters too) the texture is as continuous as possible on the surface of the model (if two faces are adjacent, the texture continues on the adjacent face where it left off) the model is closed (all faces are completely enclosed by other faces) A few notes. This mapping will occur before triangulation. I realize there are ways to do this by hand and it's probably a hard problem to automatically map textures in general, but since these textures are seamless and I just need uniform coverage it seems like an easier problem. I'm looking for an algorithmic approach to this that I can apply in general, not a tool that does it. What approach would work for this, is there an existing one? (I assume so)

• AI control for a ship with physics model

  - by Petteri Hietavirta

  I am looking for ideas how to implement following in 2D space. Unfortunately I don't know much about AI/path finding/autonomous control yet. Let's say this ship can move freely but it has mass and momentum. Also, external forces might affect it (explosions etc). The player can set a target for the ship at any time and it should reach that spot and stop. Without physics this would be simple, just point to the direction and go. But how to deal with existing momentum and then stopping on the spot? I don't want to modify ship's placement directly. edit: Just to make clear, the physics related math of the ship itself is not the problem.
