• How to 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.

• Getting collision detection in Pygames

  - by user36010

  I am writing a game in Pygame, I want to get collision detection. The aim is when a object hits another, the target object disappears. I want to avoid having classes and just have my code class less for now, in one script. This makes it difficult to get collision detection because the Rect method in Pygame is called on by an object(class). The logic I want to achieve is: object hits a target object target object disappears. is there an easy way to achieve this?(with minimal code possible)

• XNA 2D Rotated Rectangle Collision Response

  - by Kyle Uithoven

  I am using Rotated Rectangles which collide using the Separating Axis Theorem and they work perfectly fine for collision detection using Intersects and Contains. However, I am starting to use faster objects in my game now and there is the issue of the two object overlapping during collision due to their higher velocities. I would like to do a collision response where I find out how much they are overlapping in the X and Y and put position them outside of each other. I would like to use something like this: http://go.colorize.net/xna/2d_collision_response_xna/index.html. But I am having some issues trying to adapt this to handle the rotation of the bounds. Is this possible? Are there any resources out there that I can look at?

• Easiest Way to Get Started With 3D?

  - by ryebread761

  I'm looking at getting into 3D game development and am wondering what would be the best, quickest engine to get started with. I need to be able to develop on a Macintosh with it. I know Java, and PHP mainly but have worked in many others. At this point, I feel I can adapt to most languages quite easy. So the programming language doesn't really matter to me. I've sorta kinda tried unity in the past and wasn't all too fond of it, so it's kind of a "I can't find anything better" resort. I'm hoping with how open I am I will find something I like more. Thanks in advance.

• How to avoid movement speed stacking when multiple keys are pressed?

  - by eren_tetik

  I've started a new game which requires no mouse, thus leaving the movement up to the keyboard. I have tried to incorporate 8 directions; up, left, right, up-right and so on. However when I press more than one arrow key, the movement speed stacks (http://gfycat.com/CircularBewitchedBarebirdbat). How could I counteract this? Here is relevant part of my code: var speed : int = 5; function Update () { if(Input.GetKey(KeyCode.UpArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } else if(Input.GetKey(KeyCode.UpArrow) && Input.GetKey(KeyCode.RightArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } else if(Input.GetKey(KeyCode.UpArrow) && Input.GetKey(KeyCode.LeftArrow)){ transform.rotation = Quaternion.AngleAxis(315, Vector3.up); } if(Input.GetKey(KeyCode.DownArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } }

• How to get several frequency ranges at the same time in fmod?

  - by Rootosaurus

  After reading documentation and tutorials about fmod I still have a question about frequency ranges. I've found how to get a frequency range using low and high pass DSP at the same time on the main channel, but I can't find how to get several ranges at the same time. For example I want, for a specific phase of my game, to hear range 400 to 600Hz and 1000 to 2000hz of the same sound. I tried to create a channel by range, but it doesn't seem to work (or maybe I do something wrong). How can I do that ? Thank you

• FBO rendering different result between Galaxy S2 and S3

  - by BruceJones

  I'm working on a pong game and have recently set up FBO rendering so that I can apply some post-processing shaders. This proceeds as so: Bind texture A to framebuffer Draw balls Bind texture B to framebuffer Draw texture A using fade shader on fullscreen quad Bind screen to framebuffer Draw texture B using normal textured quad shader Neither texture A or B are cleared at any point, this way the balls leave trails on screen, see below for the fade shader. Fade Shader private final String fragmentShaderCode = "precision highp float;" + "uniform sampler2D u_Texture;" + "varying vec2 v_TexCoordinate;" + "vec4 color;" + "void main(void)" + "{" + " color = texture2D(u_Texture, v_TexCoordinate);" + " color.a *= 0.8;" + " gl_FragColor = color;" + "}"; This works fine with the Samsung Galaxy S3/ Note2, but cause a strange effect doesnt work on Galaxy S2 or Note1. See pictures: Galaxy S3/Note2 Galaxy S3/Note2 Galaxy S2/Note Galaxy S2/Note Can anyone explain the difference?

• Assigning a different texture based on picking(XNA)

  - by Thomas Carmichael

  I'm making a game using XNA. I have some simple objects like cube and sphere, and I would like to change the texture of one face of these objects based on picking. That is, when the cursor is over one face, it turns red. The only way I've seen to do this is to overload the content processor as here: http://xbox.create.msdn.com/en-US/education/catalog/sample/picking_triangle but it seems like it shouldn't be this complicated. I'm using .x models, and would like to be able to implement this for more complex models in the future beyond cubes/spheres/etc. Is this the best/only way to go about it? I'll figure that out if that's what is necessary, but it seems that there would be a simpler solution to load a different texture to a face than I've seen, I just don't know what it is.

• How much isometric sprites can one optimize by mirroring and alike?

  - by Tom

  I am working on a basic isometric game, and am struggling to find the correct mirrors. I have managed to get SE out of SW, by scaling the sprite on X axis by -1. Same applies for NE angle. Something is bugging me, that I should be able to also mirror N to S, but I cannot manage to pull this one off. Am I just too sleepy and trying to do the impossible, or a basic -1 scale on Y axis is not enough? What are the common used mirror table for optimizing 8 angle (N, NE, E, SE, S, SW, W, NW) isometric sprites?

• Verb+Noun Parsers and Old School Visual Novels [duplicate]

  - by user38943

  This question already has an answer here: How should I parse user input in a text adventure game? 6 answers Hi I'm working on a simple old school visual novel engine in Lua. Basically I have most of the code set up besides one important feature. The Text Parser. Lets get into how words are generally structured. In the screenshot I input the command "my wish is for you to die" --How would a human understand this? my = noun/object wish = verb is = connective_equator similar to = for = connective_object (for all objects of ..) you = noun/object to = connective_action similar to do die = verb --the computer can then parse this and understand it like this (pseudo example) my = user you = get_current_label() you = "Lost Coatl" wish = user_command user_command = for all_objects of "Lost Coatl" do die() end execute user_command() What other ways do videogames use text parsers, what would be the simplest way for a newbie coder such as myself?

• Is OpenGL 1.x deprecated?

  - by QuasarDonkey

  I'm familiar with OpenGL 1.x. I typically use SDL with OpenGL 1.4 on Linux, and I've never run into problems, even on my modern system. I've read on the OpenGL site about deprecation and compatibility contexts, but I'm still unclear as to whether it's safe to continue to use old versions of OpenGL, as opposed to using old features in newer versions. When functionality is marked deprecated ... future versions of OpenGL may remove it. Does deprecation simply imply that those functions can't be used alongside newer features? More specifically, are there any systems today (other than embedded) where OpenGL 1.x isn't available? The old-skool stuff like, glBegin, glEnd, glDrawPixels, etc. Note: I'm not a professional games developer, so you'll have to excuse my ignorance. I'm working on a mostly 2D game that I would like to keep multi-platform, supporting at least Linux, Mac, and Windows.

• Free Models and Related Animations for AI project in Unity [on hold]

  - by zhed

  Does anybody know a good website where to find free models and animations for AI projects? I'm not talking about anything good looking, like stuff you would look for when building a proper game, but, for example, a bunch of male/female models that are able to walk around and that would substitute my ugly "capsules", just to give a better -yet, still rough - idea of what's going on in the scene. On the Unity Asset Store there are a bunch of nice male/female models, but i haven't found any free general-purpose(i.e. normal walking) animation attachable to them. Any tip would we appreciated, thanks :)

• Do I lose/gain performance for discarding pixels even if I don't use depth testing?

  - by Gajoo

  When I first searched for discard instruction, I've found experts saying using discard will result in performance drain. They said discarding pixels will break GPU's ability to use zBuffer properly because GPU have to first run Fragment shader for both objects to check if the one nearer to camera is discarded or not. For a 2D game I'm currently working on, I've disabled both depth-test and depth-write. I'm drawing all objects sorted by their depth and that's all, no need for GPU to do fancy things. now I'm wondering is it still bad if I discard pixels in my fragment shader?

• Creating several instances of the same object, and selecting only one

  - by hustlerinc

  I'm playing around with making a puzzle game, haven't done that much before I run into my first problem. Basically, I want to create a certain amount of the same object/function. But without hardcoding the different instances. I think maybe an array is a good idea? and then a for loop to push the objects in? And then I need to be able to select one of these objects by clicking on it, how would I do that? How do I know which ball in the array was clicked? A loop again? I made a jsFiddle example (you need to click the orange ball to select, then you can move it around by clicking the canvas). This is what I want to do, but with more balls. How would you solve this? Help appreciated.

• Collision Detection within Player/Enemy Class

  - by user1264811

  I'm making a 2D platform game. Right now I'm just working on making a very generic Player class. I'm wondering if it would be more efficient/better practice to have an ActionListener within the Player class to detect collisions with Enemy objects (also have an ActionListener) or to handle all the collisions in the main world. Furthermore, I'm thinking ahead about how I will handle collisions with the platforms themselves. I've looked into the double boolean arrays to see which tiles players can go to and which they can't. I don't understand how to use this class and the player class at the same time. Thank you.

• Options for 2D Web/iPhone/Android, with Test Framework

  - by ashes999

  I would like to make a 2D game with one codebase that runs on iPhone, Android, and web (any flavour of web -- HTML5, Flash, Silverlight, etc.) What are my options? I should be able to write my code once, and run it anywhere. I also absolutely need the ability to write unit tests (or write a unit-testing framework) -- I cannot make sizable games without testing. Unity is good, but unity is 3d; even with hacks, the graphical assets will still be 3d. I'm after 2d, not 3d. (If you need a Mac or separate licensing for the Mac part, that's okay.)

• General usage question of vbo

  - by CSharpie

  Firstofall, I am sorry if my question is to broad. I am developing a tile based game and switched from those gl.Begin calls to using VBOs. This is kind of working allready, I managed to render a hexagonal polygon with a simple shader applied. What I am not sure is, how to implement the "whole" tile concept. Concrete the questions are: - Is it better to create 1 VBO for a single tile and render it n-Times in every different position, or render one huge VBO that represents the whole "world" - Depending on the answer above, what is the best way to draw a "linegrid". Overlay with the same vbo using the respecting polygon.mode , or is there a way to let the shader to this? - How would frustum-culling or mousepicking work then, do i need to keep the VBO-data in memory?

• When should I decide what language and platforms I will use for a project?

  - by Mikalichov

  During your development process, when is the recommended phase to decide what platform to aim for, and what language to use? I figured that it would be better to choose at the beginning what would be your target platform, as it would affect your design decisions, and limit the language you are supposed to use. However, I have heard several stories of people developing their game with whatever language they were the most confident with, and then porting it to the various platforms. So, what is the best moment to choose? Before, during, after? If there is not one best choice, what factors should affect the decision?

• What's a good way to store a series of interconnected pipe and tank objects?

  - by mars

  I am working on a puzzle game with a 6 by 6 grid of storage tanks that are connected to up to 4 tanks adjacent to them via pipes. The gameplay is concerned with combining what's in a tank with an adjacent tank via the pipe than interconnects them. Right now I store the tanks in a 6x6 array, vertical pipes in a 5x6 array, and horizontal pipes in a 6x5 array. Each tank has a reference to the object that contains both tanks and pipes and when a pipe needs to be animated filling with liquid, the selected tank just calls a method on the container object telling it to animate the pipes it is connected to (subtract 1 from row or column to find connected pipes). This feels like the wrong way of doing it, as I've also considered just giving each tank references to the pipes connected to it to access directly.

• Creating an OpenGL FPS camera: I have the position and orientation vectors, now what?

  - by Synthetix

  I have been struggling to create a first person camera in OpenGL ES 2.0 without using gluLookAt(). I grab the camera's orientation vectors (the way it's looking) from the current modelview matrix, and use that to calculate the new forward/backward (Z) translation value. I then calculate the strafe (X) value from the dot product of Z and Y (which is always 1.0). So, I have all the information I need to create a view matrix, but how do I do that without using gluLookAt? Almost all the examples I've seen use gluLookAt, but no such function exists in OpenGL ES 2.0. Besides, one of the moderators on cprogramming.com mentioned that gluLookAt is not appropriate for FPS cameras: http://cboard.cprogramming.com/game-programming/135390-how-properly-move-strafe-yaw-pitch-camera-opengl-glut-using-glulookat.html I am really confused by all the conflicting information I'm getting. I just want to create a first person camera that goes forward (W,S keys), side-to-side (A,D keys) and rotates around its center (Y axis only), Wolfenstein style. Any help on this would be much appreciated!

• Effecient finding of long-range spotting targets

  - by nihohit

  I'm creating a top-down 2d strategy game, with a square grid map. So far, I've used Bresenham's line drawing algorithm in a circle to determine what's in LOS of each unit, and then targedt one of the targets in the circle. Now I find that this limits my units to shoot only at targets that they see. I want to extend my targeting algorithm to target any other unit in range of my weapon, even if they're out of sight range of this given unit, if they're "spotted" by another friendly unit. In other words, I want to enable usage of weapons with ranges longer than sight range. Is there a better way than iterating over all sighted units and computing range and LOSto each of them?

• Tile transitions - external vs internal

  - by omgnoseat

  I've been looking at a couple of games and noticed that the transitions between tiles are handled somewhat different. I was wondering which methods are to be used in different situations and why. I'm currently using internal edges in a top-down game, and it's working out so far. But I don't want to run into problems later on, and have to redo the whole tileset. I noticed that platforming games mostly use the internal edges, and top-down games mostly use external and hybrid transitions. I can see how these tiles are used to create "depth" in top-down games, where the player apears to be standing in front of a wall for example. But it seems unlikely that such a small feature decides the entire method for tile transitions. You could always alter the bounding box to create the same effect.

• libgdx - collision detection with tiled map java

  - by user2875021

  currently, I am working on a 2d rpg game which is similar to final fantasy 1-4. I can load up a tiled map and the sprite can walk freely on the map. However, I will like to create a wall for it to stop walking through it. I created three tiled layer Background, Collision, Overhead and one Collision object layer with rectangles only. "How do I handle collisions with the object layer in the tiled map?" "Do I have to create every single rectangle that is in the object layer with Rectangle rectangle = new Rectangle() and rectangle.set(x, y, width, height)in the code?" Thank you very much in advance. Any help is greatly appreciated!

• How to find 2D grid cells swept by a moving circle?

  - by Nevermind

  I'm making a game based on a 2D grid, with some cells passable and some not. Dynamic objects can move continuously, independent of the grid, but need to collide with impassable cells. I wrote an algorithm to trace a ray against the grid, that gives me all cells that ray intersects. However, actual object are not point-sized; I'm currently representing them as circles. But I can't figure out an effective algorithm to trace a moving circle. Here's a picture of what I need: The numbers show in what order the circle collides with grid cells. Does anybody know the algorithm to find these collisions? Preferably in C#. Update The circle can be bigger than a single grid cell.
