  • Will we see a trend of stereoscopic 3D games coming up in the near future?

    - by Vish
    I've noticed that the trend of movies is diving into the world of movies with 3-dimensional camera.For me it provoked a thought as if it was the same feeling people got when they saw a colour movie for the first time, like in the transition from black and white to colour it is a whole new experience. For the first time we are experiencing the Z(depth) factor and I really mean when I said "experiencing". So my question is or maybe if not a question, but Is there a possibility of a genre of 3d camera games upcoming?

  • Box2D platformer movement. Should i mess with velocity?

    - by Romeo
    I have a platformer game in which I implemented the movement using a wheel attached to the hero. For jumping I use this: player.body.applyLinearImpulse(new Vec2(0, 30000000), player.body.getPosition()); The problem is that the xVelocity doesn't remain the same during the jump so it isn't looking natural. Is there any way to modify only the x velocity of the body so that before jumping I store it in a variable and after jumping I apply it to the body? I hope you understand what I am trying to say.

  • Looking for games in environments similar to a pinball table

    - by chaosTechnician
    I'm on a team of students working on a third-person adventure game that takes place inside a pinball machine (like, small scale, on the surface, avoiding pinballs, etc). One of my responsibilities on the project is to find games that are similar to this concept in appearance and/or gameplay for reference. So, does anyone know of games (other than pinball) that takes place in a pinball-like environment? Or, adventure games that take place in small, cramped environments with multiple paths around the world? Or games in which the player is often bombarded with balls (or other similar unintelligent obstacles)? Or games that take place on a small scale?

  • 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)?

  • Very basic OpenGL ES 2 error

    - by user16547
    This is an incredibly simple shader, yet I'm having a lot of trouble understanding what's wrong with it. I'm trying to send a float to my fragment shader. Its purpose is to adjust the alpha of the fragment colour. Here is my fragment shader: precision mediump float; uniform sampler2D u_Texture; uniform float u_Alpha; varying vec2 v_TexCoordinate; void main() { gl_FragColor = texture2D(u_Texture, v_TexCoordinate); gl_FragColor.a *= u_Alpha; } and below is my rendering method. I get a 1282 (invalid operation) on the GLES20.glUniform1f(u_Alpha, alpha); line. alpha is 1 (but I tried other values as well) and transparent is true: public void render() { GLES20.glUseProgram(mProgram); if(transparent) { GLES20.glEnable(GLES20.GL_BLEND); GLES20.glBlendFunc(GLES20.GL_SRC_ALPHA, GLES20.GL_ONE_MINUS_SRC_ALPHA); GLES20.glUniform1f(u_Alpha, alpha); } Matrix.setIdentityM(mModelMatrix, 0); Matrix.rotateM(mModelMatrix, 0, angle, 0, 0, 1); Matrix.translateM(mModelMatrix, 0, x, y, z); Matrix.multiplyMM(mMVPMatrix, 0, mViewMatrix, 0, mModelMatrix, 0); Matrix.multiplyMM(mMVPMatrix, 0, mProjectionMatrix, 0, mMVPMatrix, 0); GLES20.glUniformMatrix4fv(u_MVPMatrix, 1, false, mMVPMatrix, 0); GLES20.glBindBuffer(GLES20.GL_ARRAY_BUFFER, vbo[0]); GLES20.glVertexAttribPointer(a_Position, 3, GLES20.GL_FLOAT, false, 12, 0); GLES20.glBindBuffer(GLES20.GL_ARRAY_BUFFER, vbo[1]); GLES20.glVertexAttribPointer(a_TexCoordinate, 2, GLES20.GL_FLOAT, false, 8, 0); //snowTexture start GLES20.glActiveTexture(GLES20.GL_TEXTURE0); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, textureHandle[0]); GLES20.glUniform1i(u_Texture, 0); GLES20.glBindBuffer(GLES20.GL_ELEMENT_ARRAY_BUFFER, ibo[0]); GLES20.glDrawElements(GLES20.GL_TRIANGLE_STRIP, indices.capacity(), GLES20.GL_UNSIGNED_BYTE, 0); GLES20.glBindBuffer(GLES20.GL_ARRAY_BUFFER, 0); GLES20.glBindBuffer(GLES20.GL_ELEMENT_ARRAY_BUFFER, 0); if(transparent) { GLES20.glDisable(GLES20.GL_BLEND); } GLES20.glUseProgram(0); }

  • I need help with specific types of movement.

    - by IronGiraffe
    I'm adding movable crates to my game and I need some help with my movement code. The way I've set up my movement code the crate's X and Y are moved according to a vector2 unless it hits a wall. Here's the movement code: if (frameCount % (delay / 2) == 0) { for (int i = 0; i < Math.Abs(cSpeed.X); i++) { if (!Level.PlayerHit(new Rectangle(crateBounds.X + (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height))) { if (!Level.CollideTiles(crateBounds.X + (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height)) { if (cSpeed.X != 0) { crateBounds.X += Math.Sign(cSpeed.X); } else { Equalize(2); } } else { cSpeed.X = 0f; } } else { if (!Level.CollideTiles(crateBounds.X - (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height)) { if (cSpeed.X != 0) { crateBounds.X -= Math.Sign(cSpeed.X); } else { Equalize(2); } } else { cSpeed.X = 0f; } } } for (int i = 0; i < Math.Abs(cSpeed.Y); i++) { if (!Level.PlayerHit(new Rectangle(crateBounds.X, crateBounds.Y + Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height))) { if (!Level.CollideTiles(crateBounds.X, crateBounds.Y + Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height)) { crateBounds.Y += Math.Sign(cSpeed.Y); } else { cSpeed.Y = 0f; } } else { if (!Level.CollideTiles(crateBounds.X, crateBounds.Y - Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height)) { crateBounds.Y -= Math.Sign(cSpeed.Y); } else { cSpeed.Y = 0f; } } } } The frameCount and delay variables just slow down the movement somewhat. Anyway, I've added a tool to my game that acts as a gravity well (drawing objects into it's center; the closer they get to the center the faster they go) and what I'm trying to do is make it so that the crate will bounce off the player (and vice versa) when they collide. Thus far, my code only keeps the crate and player from getting stuck inside each other (the player can still get stuck under the crate, but I'll fix that later.) So what I'd like to know is how I can best make the crate bounce off the player. The other movement problem I'm having is related to another tool which allows the player to pick up crates and move around with them. The problem is that the crate's movement while being carried isn't tied to the movement script (it moves the crate itself, instead of adding to speed), which makes the crate go through walls and such. I know what I have to do: make the crate's speed match the player's speed while the player is holding it, but I need the crate to snap to a certain position (just in front of the player) when the player grabs it and it needs to switch to another position (just in front of the player on the other side) when they player faces the other direction while holding it. What would be the best way to make it switch places while keeping all the movement tied to the speed vector?

  • Switching between Discrete and Integrated GPUs

    - by void-pointer
    Hello everyone, I develop CUDA applications on my Alienware M17x portable back-breaker, which has two discrete GTX 285M GPUs and one integrated GeForce 9400M GPU. I can currently switch between them using NVIDIA's software, but I would like the ability to do so within my applications for purposes of benchmarking and general convenience. Apparently this requires the "NDA version" of NVIDIA's Driver API, which I know not how to obtain. Would using this API be the only way to accomplish what I seek, and if so, how would I obtain it? A solution using Windows APIs would also be acceptable, though less preferable to one which would leverage a cross-platform API. I have created a similar thread concerning the matter on NVIDIA's forum, which is down at the time of this writing. Thanks for reading my question; it is much appreciated!

  • Some help understanding and modifying a 2D shader

    - by electroflame
    I have a similar question as the one posed here, except that I don't wish to use a 1D Color Palette. I simply wish to have it display 1 color of my choosing (red, for example). I plan to use this as a "shield" effect for a 2D ship. I also wish to understand how it works a little bit better, as I'll be the first to admit that shaders in general are not my strongest suit. I'm not asking for an overview of HLSL (as that is too broad of a subject), just an explanation of how this shader works, and the best way to implement it in a 2D game. Code examples would be ideal (even if they are theoretical) but if the answer is explained well enough, I might be able to manage with plain old text. This is also in XNA 4.0. Thanks in advance.

  • using lua in kobold2d to control parameters

    - by nycynik
    Is there a tutorial on using LUA in Kobold2d? I want to know if its possible to use it to control the game behavior (like max speed decrease of timer, and bonus points) by uploading a new script to the app. I found this link in the FAQ: http://www.kobold2d.com/pages/viewpage.action?pageId=917888 but it does not mention if I can replace the lua script from within the game, and reload it, is that possible? Should i just have a parameter file instead that i can download and replace?

    I'm looking for a royalty free sci-fi sounding song thats 1:00+ long, and costs less then, or is $5 usd. I want to have a nice BGM for my engine demo I'm going to release for a game I'm planing on having go commercial. I don't want to spend too much money on it, so my limit is $5 usd. I want it to be at least a 1:00 in length. Where should I look? Or even better, do you have a link to a song that meets the criteria?

  • How to get the blocks seen by the player?

    - by m4tx
    I'm writing a Minecraft-like game using Ogre engine and I have a problem. I must optimize my game, because when I try draw 10000 blocks, I have 2 FPS... So, I got the idea that blocks display of the plane and to hide the invisible blocks. But I have a problem - how do I know which blocks at a time are visible to the player? And - if you know of other optimization methods for such a game, write what and how to use them in Ogre.

  • How do I improve terrain rendering batch counts using DirectX?

    - by gamer747
    We have determined that our terrain rendering system needs some work to minimize the number of batches being transferred to the GPU in order to improve performance. I'm looking for suggestions on how best to improve what we're trying to accomplish. We logically split our terrain mesh into smaller grid cells which are 32x32 world units. Each cell has meta data that dictates the four 256x256 textures that are used for spatting along with the alpha blend data, shadow, and light mappings. Each cell contains 81 vertices in a 9x9 grid. Presently, we examine each cell and determine the four textures that are being used to spat the cell. We combine that geometry with any other cell that perhaps uses the same four textures regardless of spat order. If the spat order for a cell differs, the blend map is adjusted so that the spat order is maintained the same as other like cells and blending happens in the right order too. But even with this batching approach, it isn't uncommon when looking out across an area of open terrain to have between 1200-1700 batch count depending upon how frequently textures differ or have different texture blends are between cells. We are only doing frustum culling presently. So using texture spatting, are there other alternatives that can reduce the batch count and allow rendering to be extremely performance-friendly even under DirectX9c? We considered using texture atlases since we're targeting DirectX 9c & older OpenGL platforms but trying to repeat textures using atlases and shaders result in seam artifacts which we haven't been able to eliminate with the exception of disabling mipmapping. Disabling mipmapping results in poor quality textures from a distance. How have others batched together terrain geometry such that one could spat terrain using various textures, minimizing batch count and texture state switches so that rendering performance isn't negatively impacted?

  • Using normals in DirectX 10

    - by Dave
    I've got a working OBJ loader that loads vertices, indices, texture coordinates, and normals. As of right now it doesn't process texture coordinates or normals but it stores them in arrays and creates a valid mesh with the vertices and indices. Now I am trying to figure out how can I make the shader use the correct normal in the array for the current vertex if I can't setnormals() to my mesh. If I were to just use an index in my array of normals corresponding to the index in the vertices, how would I retrieve the current index the shader is processing? BTW: I am trying to write a blinn-phong shader technique. Also when I create the input layout and I've added the semantic NORMAL to it, how would I list the multiple semantics in that single parameter? Would I just separate it with a space? PS: If you need to see any code, just let me know.

  • 2D Polygon Triangulation

    - by BleedObsidian
    I am creating a game engine using the JBox2D physics engine. It only allows you to create polygon fixtures up to 8 vertices, To create a body with more than 8 vertices, you need to create multiple fixtures for the body. My question is, How can I split the polygons a user creates into smaller polygons for JBox2D? Also, what topology should I use when splitting the polygons and why? (If JBox2D can have up to 8 vertices, why not split polygons into 8 per polygon)

  • Using components in the XNA Game State Management example?

    - by Zolomon
    In the game state management example at the App Hub, they say that if you want to use components in the example you can extend the GameScreen to host other components inside itself. I'm having a very hard time trying to tie this up. I tried extending the GameScreen class by adding a public property of public List<DrawableGameCompnent> components { get; set; } and then add my components to that list when I initialize the current screen as well as looping over the components in the LoadContent, Update and Draw methods. However, this doesn't feel like the correct way to go - mainly because it doesn't work when I get to the implementation of my GameplayScreen. Any thoughts?

  • OpenGL ES 2.0 gluUnProject

    - by secheung
    I've spent more time than I should trying to get my ray picking program working. I'm pretty convinced my math is solid with respect to line plane intersection, but I believe the problem lies with the changing of the mouse screen touch into 3D world space. Heres my code: public void passTouchEvents(MotionEvent e){ int[] viewport = {0,0,viewportWidth,viewportHeight}; float x = e.getX(), y = viewportHeight - e.getY(); float[] pos1 = new float[4]; float[] pos2 = new float[4]; GLU.gluUnProject( x, y, 0.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos1, 0); GLU.gluUnProject( x, y, 1.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos2, 0); } Just as a reference I've tried transforming the coordinates 0,0,0 and got an offset. It would be appreciated if you would answer using OpenGL ES 2.0 code.

    If i decide to write a simple game both text and graphical (2d) what libs may i use? Assuming we are using a HTML5 compatible browser. The main things i can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but i am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (i know this exist but i dont know how easy it is to setup or use. But this isnt important to me. Its for the question).

  • Cutting out smaller rectangles from a larger rectangle

    - by Mauro Destro
    The world is initially a rectangle. The player can move on the world border and then "cut" the world via orthogonal paths (not oblique). When the player reaches the border again I have a list of path segments they just made. I'm trying to calculate and compare the two areas created by the path cut and select the smaller one to remove it from world. After the first iteration, the world is no longer a rectangle and player must move on border of this new shape. How can I do this? Is it possible to have a non rectangular path? How can I move the player character only on path? EDIT Here you see an example of what I'm trying to achieve: Initial screen layout. Character moves inside the world and than reaches the border again. Segment of the border present in the smaller area is deleted and last path becomes part of the world border. Character moves again inside the world. Segments of border present in the smaller area are deleted etc.

  • rotating menu with Actors in libgdx

    - by joecks
    I am intending to build a circular menu, with menu items equally distributed around the circle. When clicking on a menu item the circle should rotate so that the selected item is facing the top. I am using libgdx and I am not very familiar with the Actors concept, so I intuitivly tried to implement an Actor, who is drawing a texture and then transforming it by using Actions, with no success: class CircleActor extends Actor { @Override public void draw(SpriteBatch batch, float parentAlpha) { batch.draw(texture1, 100, 100); } @Override public Actor hit(float x, float y) { return this; } } and the rotate action: CircleActor circleActor = new CircleActor(); circleActor.action(Forever.$(RotateBy.$(0.1f, 0.1f))); // stage.addActor(); stage.addActor(circleActor); The texture is rectangular, but it doe not work. 1. What is wrong? 2. Is it a good approach to solve the task? Thanks!

(For example, I'd like to do some custom blending- when the destination color is dark, do one thing; when it is light, do another). It looks like I'll need to create multiple render targets and render back and forth between them. What's the best way to do this? Create my own render textures, use them, and then copy the final result into the back buffer. Create multiple back buffers, render between them, and then present the last one that was rendered to. Create one render texture, and one back buffer, render between them, and just ensure that the back buffer is the final target rendered to I'm not sure which of these is possible, and if there are any performance issues that aren't obvious. Clearly my preference would be to have 2 rather than 3 default render targets, if possible.
