• Problems in exporting terrain from autodesk 3ds

  - by Jatin Kumar

  i am trying to make small counter strike sort of game and for the terrain part i have exported the terrain in 3ds format from Autodesk 3ds-max and imported the same in opengl using lib3ds. Its working fine but with few problems: The terrain is mainly made up of some cubical boxes with texture on them and placed on a big flat surface with boundary wall. In opengl i have enabled anti aliasing but still there is too much aliasing on the boundaries (visible when rotating the camera). I have tiled the floor with some image but in opengl it is just the single image stretched over the complete surface. I have exported animated model (Skelton+mesh+material+animation) from 3ds and used cal3d library for reading the same. Model has a gun also which is not appearing in opengl and it too has too much of aliasing problem. I have googled around but couldn't find any relevant solutions. Thanks in advance

• Opposite Force to Apply to a Collided Rigid Body?

  - by Milo

  I'm working on the physics for my GTA2-like game so I can learn more about game physics. The collision detection and resolution are working great. I'm now just unsure how to compute the force to apply to a body after it collides with a wall. My rigid body looks like this: /our simulation object class RigidBody extends Entity { //linear private Vector2D velocity = new Vector2D(); private Vector2D forces = new Vector2D(); private float mass; private Vector2D v = new Vector2D(); //angular private float angularVelocity; private float torque; private float inertia; //graphical private Vector2D halfSize = new Vector2D(); private Bitmap image; private Matrix mat = new Matrix(); private float[] Vector2Ds = new float[2]; private Vector2D tangent = new Vector2D(); private static Vector2D worldRelVec = new Vector2D(); private static Vector2D relWorldVec = new Vector2D(); private static Vector2D pointVelVec = new Vector2D(); private static Vector2D acceleration = new Vector2D(); public RigidBody() { //set these defaults so we don't get divide by zeros mass = 1.0f; inertia = 1.0f; setLayer(LAYER_OBJECTS); } protected void rectChanged() { if(getWorld() != null) { getWorld().updateDynamic(this); } } //intialize out parameters public void initialize(Vector2D halfSize, float mass, Bitmap bitmap) { //store physical parameters this.halfSize = halfSize; this.mass = mass; image = bitmap; inertia = (1.0f / 20.0f) * (halfSize.x * halfSize.x) * (halfSize.y * halfSize.y) * mass; RectF rect = new RectF(); float scalar = 10.0f; rect.left = (int)-halfSize.x * scalar; rect.top = (int)-halfSize.y * scalar; rect.right = rect.left + (int)(halfSize.x * 2.0f * scalar); rect.bottom = rect.top + (int)(halfSize.y * 2.0f * scalar); setRect(rect); } public void setLocation(Vector2D position, float angle) { getRect().set(position.x,position.y, getWidth(), getHeight(), angle); rectChanged(); } public Vector2D getPosition() { return getRect().getCenter(); } @Override public void update(float timeStep) { doUpdate(timeStep); } public void doUpdate(float timeStep) { //integrate physics //linear acceleration.x = forces.x / mass; acceleration.y = forces.y / mass; velocity.x += (acceleration.x * timeStep); velocity.y += (acceleration.y * timeStep); //velocity = Vector2D.add(velocity, Vector2D.scalarMultiply(acceleration, timeStep)); Vector2D c = getRect().getCenter(); v.x = getRect().getCenter().getX() + (velocity.x * timeStep); v.y = getRect().getCenter().getY() + (velocity.y * timeStep); setCenter(v.x, v.y); forces.x = 0; //clear forces forces.y = 0; //angular float angAcc = torque / inertia; angularVelocity += angAcc * timeStep; setAngle(getAngle() + angularVelocity * timeStep); torque = 0; //clear torque } //take a relative Vector2D and make it a world Vector2D public Vector2D relativeToWorld(Vector2D relative) { mat.reset(); Vector2Ds[0] = relative.x; Vector2Ds[1] = relative.y; mat.postRotate(JMath.radToDeg(getAngle())); mat.mapVectors(Vector2Ds); relWorldVec.x = Vector2Ds[0]; relWorldVec.y = Vector2Ds[1]; return relWorldVec; } //take a world Vector2D and make it a relative Vector2D public Vector2D worldToRelative(Vector2D world) { mat.reset(); Vector2Ds[0] = world.x; Vector2Ds[1] = world.y; mat.postRotate(JMath.radToDeg(-getAngle())); mat.mapVectors(Vector2Ds); worldRelVec.x = Vector2Ds[0]; worldRelVec.y = Vector2Ds[1]; return worldRelVec; } //velocity of a point on body public Vector2D pointVelocity(Vector2D worldOffset) { tangent.x = -worldOffset.y; tangent.y = worldOffset.x; pointVelVec.x = (tangent.x * angularVelocity) + velocity.x; pointVelVec.y = (tangent.y * angularVelocity) + velocity.y; return pointVelVec; } public void applyForce(Vector2D worldForce, Vector2D worldOffset) { //add linear force forces.x += worldForce.x; forces.y += worldForce.y; //add associated torque torque += Vector2D.cross(worldOffset, worldForce); } @Override public void draw( GraphicsContext c) { c.drawRotatedScaledBitmap(image, getPosition().x, getPosition().y, getWidth(), getHeight(), getAngle()); } public Vector2D getVelocity() { return velocity; } public void setVelocity(Vector2D velocity) { this.velocity = velocity; } } The way it is given force is by the applyForce method, this method considers angular torque. I'm just not sure how to come up with the vectors in the case where: RigidBody hits static entity RigidBody hits other RigidBody that may or may not be in motion. Would anyone know a way (without too complex math) that I could figure out the opposite force I need to apply to the car? I know the normal it is colliding with and how deep it collided. My main goal is so that say I hit a building from the side, well the car should not just stay there, it should slowly rotate out of it if I'm more than 45 degrees. Right now when I hit a wall I only change the velocity directly which does not consider angular force. Thanks!

• Game-a-Week 2 (The Sequel)

  - by Matt Christian

  After finishing Game-a-Week One I immediately wanted to go back and begin refactoring the code although I also wanted to work on a game demo idea I've had for quite awhile.  I tried doing both over the holiday weekend while up north (without internet!) and eventually hit a wall with an error. Today I am going to restart my refactoring and updates by starting Game-a-Week 2.  This challenge is to do the following: Refactor the old code Add a handful of new features to the demo This sounds simple enough but will be quite a challenge to finish in just around a week.  I have an idea on how I want to refactor the code, but the new features I'd like to implement will be tricky.  I'm going to try to implement: Quest giving / finishing / NPC's Quest Log Menu Inventory giving / receiving Inventory Menu This Game-a-Week is much more design oriented although will provide a good challenge for programming as well.  Wish me luck!

• Should I add old code into my repository?

  - by Ben Brocka

  I've got an SVN repository of a PHP site and the last programmer didn't use source control properly. As a result, only code since I started working here is in the Repo. I have a bunch of old copies of the full code base saved in files as "backups" but they're not in source control. I don't know why most of the copies were saved nor do I have any reasonable way to tag them to a version number. Due to upgrades to the frameworks and database drivers involved, the old code is quite defunct; it no longer works on the current server config. However, the previous programmers had some...unique...logic, so I hate to be completely without old copies to refer to what on earth they were doing. Should I keep this stuff in version control? How? Wall off the old code in separate Tags/branches?

• How did programmers resolve their problems before the internet?

  - by 9a3eedi

  When programming, anytime I get stuck, perhaps with a compiler error that doesn't make sense, or from a GUI function that didn't do what I expected, I automatically google my problem, find someone else that faced the same thing, and read what's going on and why I'm getting the problem. Before the internet, how did people handle these situations? People used to read books and manuals more, I know. But books don't explain everything, like the odd compiler problem that you get sometimes, or nothing showing up on your screen despite you clearly writing correct OpenGL code. How did people cope when facing challenges? Did they simply "bash their head" on the wall till they figured it out? Is there something people used to do regularly on the side that gave them the ability to get themselves unstuck more easily? Were libraries/compilers much simpler back then? I've been asking this question because I sometimes feel guilty depending on Google so much when I'm pretty sure programmers before my time were more independent when it comes to facing these matters.

• How can I implement an Iris Wipe effect?

  - by Vandell

  For those who doesn't know: An iris wipe is a wipe that takes the shape of a growing or shrinking circle. It has been frequently used in animated short subjects, such as those in the Looney Tunes and Merrie Melodies cartoon series, to signify the end of a story. When used in this manner, the iris wipe may be centered around a certain focal point and may be used as a device for a "parting shot" joke, a fourth wall-breaching wink by a character, or other purposes. Example from flasheff.com Your answer may or may not include a coding sample, a language agnostic explanation is considered enough.

• How to deal with project managers who micromanage?

  - by entens

  Perhaps I'm just naive, but when I try to decipher the wall of tasks I'm targeted to do over the course of a week, I just can't help but think whoever builds the project schedule needs to get some remedial training on basic project management. For example, I am assigned 13 tasks today, the shortest lasting .13 days (default time metric in Microsoft Project), and the longest lasting .75 days. I can't help but think that it is blatant micromanagement scheduling projects in sub 10 minute intervals. The effects of management are becoming evident in slipped tasks, resource assignment exceeding capacity by a factor of two at some points in time, and spending more time clearing tasks and figuring out what comes next than actually doing work. How can I convince the project manager to create tasks with larger duration and to see the larger picture?

• Direct Code Support?

  - by Josh Kahane

  A few times in the past I've hit a major wall and simply couldn't progress with a certain aspect of an app as Im a beginner and still learning the ropes (Objective-C specifically). I was curious if anyone knows of any services which support programmers in real time, paid or free and will over video, audio or text chat sit and work a problem out till its fixed and look through your code? I understand Stackoverflow does a super job at this! However Im in need of something a little more tailored where someone can spend a little time to sit and look and what Im dealing with and delve into my a code if need be. Thanks.

• If I were to claim I knew C++, what libraries would you expect me to know?

  - by Peter Smith

  I'm unsure as to the definition of knowing a programming language, so I'm picking C++ as an example. How much does it take to someone to be qualified as knowing C++? Should they just know the basic syntax? Template and generic-programming? Compiler flags and their purposes (Wall, the difference between O1, O2 and O3)? STL? Garbage collection strategies? Boost? Common libraries like zlib, curl, and libxml2?

• Could someone break this nasty habit of mine please?

  - by MimiEAM

  I recently graduated in cs and was mostly unsatisfied since I realized that I received only a basic theoretical approach in a wide range of subjects (which is what college is supposed to do but still...) . Anyway I took the habit of spending a lot of time looking for implementations of concepts and upon finding those I will used them as guides to writing my own implementation of those concepts just for fun. But now I feel like the only way I can fully understand a new concept is by trying to implement from scratch no matter how unoptimized the result may be. Anyway this behavior lead me to choose by default the hard way, that is time consuming instead of using a nicely written library until I hit my head again a huge wall and then try to find a library that works for my purpose.... Does anyone else do that and why? It seems so weird why would anyone (including me) do that ? Is it a bad practice ? and if so how can i stop doing that ?

• Right tool for the job(html5 vs silverlight)

  - by Jargo

  I have been tasked to develop a web based offer request application for bathrooms and I am asking opinions on which tool should I choose. I have narrowed options down to two (html5 and silverlight). Most of the application consists of basic UI elements that could be achieved with html4. However most challenging part is the design view for the bathroom. User first defines size of the bathroom by giving dimensions. When the dimensions are defined the application renders an empty bathroom floorplan and user can start dragging&dropping furniture on to it. Some furniture have rules where they can be dragged. For example sinks can only be dragged next to a wall. I know that this functionality can be achieved with silverlight but what about html5 ? I know that Canvas element can be used to draw graphics, but can it render the bathroom smoothly as user drags a piece furniture on it?

• How do you turn off touch on a Wacom Bamboo CTH-470?

  - by Foxx

  I bought my girlfriend a Wacom Bamboo CTH-470 recently and it is running well after installing wacom-dkms. I have now run into a wall that I don't know how to get around. The touch on the tablet will not turn off. I am running Ubuntu 12.04 Beta 2. I have tried turning the touch off from the wacom settings in the settings menu. The pen and touch both work perfectly fine, it is just that the touch drives her insane when trying to draw in myPaint.

• Bouncing ball slowing down over time

  - by user46610

  I use the unreal engine 4 to bounce a ball off of walls in a 2D space, but over time the ball gets slower and slower. Movement happens in the tick function of the ball FVector location = GetActorLocation(); location.X += this->Velocity.X * DeltaSeconds; location.Y += this->Velocity.Y * DeltaSeconds; SetActorLocation(location, true); When a wall gets hit I get a Hit Event with the normal of the collision. This is how I calculate the new velocity of the ball: FVector2D V = this->Velocity; FVector2D N = FVector2D(HitNormal.X, HitNormal.Y); FVector2D newVelocity = -2 * (V.X * N.X + V.Y * N.Y) * N + V; this->Velocity = newVelocity; Over time, the more the ball bounced around, the velocity gets smaller and smaller. How do I prevent speed loss when bouncing off walls like that? It's supposed to be a perfect bounce without friction or anything.

• Internet stopped working after aircrack install (can still connect to my router). Suggestions?

  - by Dan

  I'm sure I did something dumb during the install for aircrack, but I have no clue what. Like I said, I can connect to my router (not trying to crack, simply logging into it), I just can't get internet access. To make this more interesting, the machine is dual booted and when I log into Windows I have zero issues. I feel like some driver may have been messed up in the process, but I'm not sure if that's a reasonable assumption or how exactly to check that. Also, can't revert to backup as there are none. Suggestions on how to trouble-shoot would be appreciated. EDIT: Hard-wiring to the wall I can get internet access on the Ubuntu side... PS- I know this is a stretch as far as fitting the Ubuntu section, but no other stackoverflow sites seemed to fit better.

• Projectiles in tile mapped turn-based tactics game?

  - by Petteri Hietavirta

  I am planning to make a Laser Squad clone and I think I have most of the aspects covered. But the major headache is the projectiles shot/thrown. The easy way would be to figure out the probability of hit and just mark miss/hit. But I want to be able to have the projectile to hit something eventually (collateral damage!). Currently everything is flat 2D tile map and there would be full (wall, door) and half height (desk, chair, window) obstacles. My idea is to draw an imaginary line from the shooter to the target and add some horizontal&vertical error based on the player skills. Then I would trace the modified path until it hits something. This is basically what the original Laser Squad seems to do. Can you recommend any algorithms or other approaches for this?

• URL Rewrite http to https EXCEPT files in a specific subfolder

  - by BrettRobi

  I am trying to force all traffic on my web site to use HTTPS, using the URL Rewrite 2.0 module added to IIS 7.5. I got that working and now have a need to exclude a couple of pages from using SSL. So I need a rule to rewrite all URL except those referencing this folder to HTTPS. I've been banging my head against the wall on this and am hoping someone can help. I tried creating a rule to match all URL except those in a nossl subfolder as in this example: <rule name="HTTP to HTTPS redirect" enabled="true" stopProcessing="true"> <match url="(/nossl/.*)" negate="true" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <add input="{HTTPS}" pattern="off" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Found" /> </rule> But this doesn't work. Can anyone help?

• How do I fix dragging windows to the adjacent workspace?

  - by Bill O'Dwyer

  I installed CompizConfig-Settings-Manager and I put on all the settings I liked and had in 11.10, including the ability to drag my windows to the adjacent workspace. It's under the Desktop Wall section, on the Edge Flipping tab and I've checked "Edge Flip Move" and "Edge Flip DnD." In 11.10, the movement was smooth between each workspace, and the window would still be "grabbed" in the same place. In 12.04, it's leaving the window behind and the mouse appears to be "grabbing" nothing, but I'm still holding onto the window, and I can still move and place it within the workspace (or indeed the previous workspace as it won't appear in the desired place until I drag the mouse all the way to the edge of the screen). Any way to fix this? I'm running 12.04 beta 2.

• Hosting cross-domain Silverlight applications (XAP)

  In the Silverlight world, there are two types of cross-domain things that may leave some banging their head against a wall for a while. The first involves making network-based calls (WebClient, HttpWebRequest, etc) to services hosted on a domain other than the one that is the site of origin for the XAP. This is solved by ensuring the service provider enables a clientaccesspolicy.xml file for their service. More information here: Cross Domain Policy Files with Silverlight. NOTE: site of origin is...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
