  • Box2D Static-Dynamic body joint eliminates collisions

    - by andrewz
    I have a static body A, and a dynamic body B, and a dynamic body C. A is filtered to not collide with anything, B and C collide with each other. I wish to create a joint between B and A. When I create a joint (ex. revolute), B no longer collides with C - C passes through it as if it does not exist. What am I doing wrong? How can adding a joint prevent a body from colliding with another body it used to? EDIT: I want to join B with A, and have B collide with C, but not A collide with C. In realistic terms, I'm trying to create a revolute joint between a wheel (B) and a wall (A), and have a box (C) hit the wheel and the wheel would then rotate. EDIT: I create a the simplest revolute joint I can with these parameters (C++): b2RevoluteJointDef def; def.Initialize(A, B, B -> GetWorldCenter()); world -> CreateJoint(&def);

  • Bullet Physic: Transform body after adding

    - by Mathias Hölzl
    I would like to transform a rigidbody after adding it to the btDiscreteDynamicsWorld. When I use the CF_KINEMATIC_OBJECT flag I am able to transform it but it's static (no collision response/gravity). When I don't use the CF_KINEMATIC_OBJECT flag the transform doesn't gets applied. So how to I transform non-static objects in bullet? DemoCode: btBoxShape* colShape = new btBoxShape(btVector3(SCALING*1,SCALING*1,SCALING*1)); /// Create Dynamic Objects btTransform startTransform; startTransform.setIdentity(); btScalar mass(1.f); //rigidbody is dynamic if and only if mass is non zero, otherwise static bool isDynamic = (mass != 0.f); btVector3 localInertia(0,0,0); if (isDynamic) colShape->calculateLocalInertia(mass,localInertia); btDefaultMotionState* myMotionState = new btDefaultMotionState(); btRigidBody::btRigidBodyConstructionInfo rbInfo(mass,myMotionState,colShape,localInertia); btRigidBody* body = new btRigidBody(rbInfo); body->setCollisionFlags(body->getCollisionFlags()|btCollisionObject::CF_KINEMATIC_OBJECT); body->setActivationState(DISABLE_DEACTIVATION); m_dynamicsWorld->addRigidBody(body); startTransform.setOrigin(SCALING*btVector3( btScalar(0), btScalar(20), btScalar(0) )); body->getMotionState()->setWorldTransform(startTransform);

    Hi All, I'm running into a similar problem as this: link text I've done the fix as in the answer but now I end up with an error a couple lines later: $$([overlay = (new Element("div", {id: "mbOverlay"})).addEvent("click", close), center = new Element("div", {id: "mbCenter"})]).setStyle is not a function [Break on this error] ]).setStyle("display", "none") It's on this page: link text When you click on 'showreel' it should pop up into the media box, but instead it just goes to a new page. Any help would be much appreciated. Thanks!

  • Match multiple terms within <body> tags

    - by Jeepstone
    I've want to match any occurrence of a search term (or list of search terms) within the tags of a document. My current solution uses preg (within a Joomla plugin) $pattern = '/matchthisterm/i'; $article->text = preg_replace($pattern,"<span class=\"highlight\">\\0</span>",$article->text); But this replaces everything within the HTML of the document so I need to match the tags first. Is this even the best way to achieve this?

  • Bullet Physics - Casting a ray straight down from a rigid body (first person camera)

    - by Hydrocity
    I've implemented a first person camera using Bullet--it's a rigid body with a capsule shape. I've only been using Bullet for a few days and physics engines are new to me. I use btRigidBody::setLinearVelocity() to move it and it collides perfectly with the world. The only problem is the Y-value moves freely, which I temporarily solved by setting the Y-value of the translation vector to zero before the body is moved. This works for all cases except when falling from a height. When the body drops off a tall object, you can still glide around since the translate vector's Y-value is being set to zero, until you stop moving and fall to the ground (the velocity is only set when moving). So to solve this I would like to try casting a ray down from the body to determine the Y-value of the world, and checking the difference between that value and the Y-value of the camera body, and disable or slow down movement if the difference is large enough. I'm a bit stuck on simply casting a ray and determining the Y-value of the world where it struck. I've implemented this callback: struct AllRayResultCallback : public btCollisionWorld::RayResultCallback{ AllRayResultCallback(const btVector3& rayFromWorld, const btVector3& rayToWorld) : m_rayFromWorld(rayFromWorld), m_rayToWorld(rayToWorld), m_closestHitFraction(1.0){} btVector3 m_rayFromWorld; btVector3 m_rayToWorld; btVector3 m_hitNormalWorld; btVector3 m_hitPointWorld; float m_closestHitFraction; virtual btScalar addSingleResult(btCollisionWorld::LocalRayResult& rayResult, bool normalInWorldSpace) { if(rayResult.m_hitFraction < m_closestHitFraction) m_closestHitFraction = rayResult.m_hitFraction; m_collisionObject = rayResult.m_collisionObject; if(normalInWorldSpace){ m_hitNormalWorld = rayResult.m_hitNormalLocal; } else{ m_hitNormalWorld = m_collisionObject->getWorldTransform().getBasis() * rayResult.m_hitNormalLocal; } m_hitPointWorld.setInterpolate3(m_rayFromWorld, m_rayToWorld, m_closestHitFraction); return 1.0f; } }; And in the movement function, I have this code: btVector3 from(pos.x, pos.y + 1000, pos.z); // pos is the camera's rigid body position btVector3 to(pos.x, 0, pos.z); // not sure if 0 is correct for Y AllRayResultCallback callback(from, to); Base::getSingletonPtr()->m_btWorld->rayTest(from, to, callback); So I have the callback.m_hitPointWorld vector, which seems to just show the position of the camera each frame. I've searched Google for examples of casting rays, as well as the Bullet documentation, and it's been hard to just find an example. An example is really all I need. Or perhaps there is some method in Bullet to keep the rigid body on the ground? I'm using Ogre3D as a rendering engine, and casting a ray down is quite straightforward with that, however I want to keep all the ray casting within Bullet for simplicity. Could anyone point me in the right direction? Thanks.

  • determine collision angle on a rotating body

    - by jorb
    update: new diagram and updated description I have a contact listener set up to try and determine the side that a collision happened at relative to the a bodies rotation. One way to solve this is to find the value of the yellow angle between the red and blue vectors drawn above. The angle can be found by taking the arc cosine of the dot product of the two vectors (Evan pointed this out). One of my points of confusion is the difference in domain of the atan2 function html canvas coordinates and the Box2d rotation information. I know I have to account for this somehow... SS below questions: Does Box2D provide these angles more directly in the collision information? Am I even on the right track? If so, any hints? I have the following javascript so far: Ship.prototype.onCollide = function (other_ent,cx,cy) { var pos = this.body.GetPosition(); //collision position relative to body var d_cx = pos.x - cx; var d_cy = pos.y - cy; //length of initial vector var len = Math.sqrt(Math.pow(pos.x -cx,2) + Math.pow(pos.y-cy,2)); //body angle - can over rotate hence mod 2*Pi var ang = this.body.GetAngle() % (Math.PI * 2); //vector representing body's angle - same magnitude as the first var b_vx = len * Math.cos(ang); var b_vy = len * Math.sin(ang); //dot product of the two vectors var dot_prod = d_cx * b_vx + d_cy * b_vy; //new calculation of difference in angle - NOT WORKING! var d_ang = Math.acos(dot_prod); var side; if (Math.abs(d_ang) < Math.PI/2 ) side = "front"; else side = "back"; console.log("length",len); console.log("pos:",pos.x,pos.y); console.log("offs:",d_cx,d_cy); console.log("body vec",b_vx,b_vy); console.log("body angle:",ang); console.log("dot product",dot_prod); console.log("result:",d_ang); console.log("side",side); console.log("------------------------"); }

  • Cocos2d and Body with few collision shapes using chipmunk

    - by Eimantas
    I'm using Cocos2d (0.99.5) with chipmunk physics engine. Currently I'm trying to place a body into space which is combined from few circle shapes. Let's say I have a corresponding sprite image with displays atom (nucleus + 3 electrons around it. Something like this without orbit lines). In it's simplest form - only one circle shape at the center should be enough which would detect collisions from other objects with nucleus. Now I'd like to add other circle shapes for each electron. How can I do that? Now when I add those shapes to the body and add the body into chipmunk space - the shapes (together with the body/sprite) start flickering and spinning with no recognizable pattern (or reason for that matter).

  • Break the object body

    - by Siddharth
    In my game, I want to break the object body creating slicing effect. After research I found that I have to use ray casting but I don't know how to use it. If some one know how to break the physics body then please provide information to me. EDIT : I don't have any logic how to do that in andengine. Only I have some link to do slicing http://www.emanueleferonato.com/2012/03/05/breaking-objects-with-box2d-the-realistic-way/ Yes I have to slice physics body into two parts. My physics body have 2d objects.

  • Moving the jBullet collision body to with the player object

    - by Kenneth Bray
    I am trying to update the location of the rigid body for a player class, as my player moves around I would like the collision body to also move with the player object (currently represented as a cube). Below is my current update method for when I want to update the xyz coords, but I am pretty sure I am not able to update the origin coords? : public void Update(float pX, float pY, float pZ) { posX = pX; posY = pY; posZ = pZ; //update the playerCube transform for the rigid body cubeTransform.origin.x = posX; cubeTransform.origin.y = posY; cubeTransform.origin.z = posZ; cubeRigidBody.getMotionState().setWorldTransform(cubeTransform); processTransformMatrix(cubeTransform); } I do not have rotation updated, as I do not actually want/need the player body to rotate at all currently. However, in the final game this will me put in place.

  • AndEngine; Box2D - high speed body overlapping, prismatic joints

    - by Visher
    I'm trying to make good suspension for my car game, but I'm getting nervous of some problems with it. At the beginning, I've tried to make it out of one prismatic joint/revolute joint per one wheel only, but surprisingly prismatic joint that should only move in Y asix moves also in X axis, if car travels very fast, or even on low speeds if there's setContinuousPhysics = true. This causes wheels to "shift back", moving them away from axle. Now I've tried to add some bodies that will keep it in place: Suspension helper collides with spring only, wheel doesn't collide with spring&helper&vehicle body This is how I create those elements: rect = new Rectangle(1100, 1350, 200, 50, getVertexBufferObjectManager());

  • Cocos2d/Cocos2d-x Attaching an arrow (sprite) to another body sprite (person)

    - by Satchmo Brown
    I am trying to set up a simple bow and arrow game. When the arrow hits the enemy body, the arrow's body is deleted and the arrow sprite continues to update, keeping the position correct in relation to the enemy it hit. Picture an arrow sticking into a body and that body still rotating and moving. My problem is that the rotation is completely wrong when the enemy rotates. I know how to do this in 3d with matrix transformation but I can't seem to figure it out in 2d with Cocos. Here is my method. I save offset at which the arrow hit the enemy. Every frame, I make the rotation of the sprite match the rotation of the enemy. Then, I apply the offset I took initially which is where the arrow hit the enemy. When they rotate, they rotate about their respective anchors and I am wondering if I need to set the anchor of the arrow to the center of the sprite. Does anyone know of an easy way to do this. If not, I will try to create an algorithm where the anchor is set to the offset divided by the width and height of the sprite image hopefully giving me the correct anchor values. Then I assume I need to reposition the sprite. Does anyone have a simpler way to do this?

What's the benefit? what is the reason for using position absolute? why did they set the background/color/font on the html and not the body? Is there a difference? Or is it just preference?

  • How do I get the compression on specific dynamic body

    - by Mike JM
    Sorry, I could not find any tag that would suit my question. Let me first show you the image and then write what I want to do: I'm using box2D. As you can see there are three dynamic bodies connected to each other (think of it as a table from front view).The LEG1 and LEG2 are connected to the static body. (it's the ground body). Another dynamic body is falling onto the table. I need to get the compression in the LEG1 and LEG2 separately. Joints have GetReactionForce() function which returns a b2Vec, which in turn has Length() and LengthSqd functions. This will give the total sum of the forces in any taken joint. But what I need is forces in individual bodies that are connected with joints. Once you connect several bodies with a single joint it again will show the sum of forces which is not useful.Here's the case iI'm talking about:

Now I want to show the path where the body will go when the user have touched. If you have played Angry Birds or Basket Ball Shoot or any other which have projectile motion with a path shown you will get my point. I want to show the white dots which are shown in those games.

    Hey i have issue regarding jump sprite body. In my code i am using moveLeft and moveRight Button and when i am press moveRight Button using following code if (moveRight.active==YES) { b2Vec2 force=b2Vec2(4,0); ballBody->SetLinearVelocity(force); } Its move perfectly and When i release this Button than sprite body stop using following code else { b2Vec2 force=b2Vec2(0,0); ballBody->SetLinearVelocity(force); } But when i put this else part then jump can not done. My jump code is following if (jumpSprite.active==YES) { NSLog(@"Jump Sprite"); b2Vec2 locationWorld; locationWorld=b2Vec2(0.0f,4.0f); double force=ballBody->GetMass(); ballBody->ApplyLinearImpulse(force*locationWorld, ballBody->GetWorldCenter()); } If i remove else part then jump will perform complete but sprite body can not stop after release button. So what to do?? Thanks in advance

  • Rewind request body stream

    - by Despertar
    I am re-implementing a request logger as Owin Middleware which logs the request url and body of all incoming requests. I am able to read the body, but if I do the body parameter in my controller is null. I'm guessing it's null because the stream position is at the end so there is nothing left to read when it tries to deserialize the body. I had a similar issue in a previous version of Web API but was able to set the Stream position back to 0. This particular stream throws a This stream does not support seek operations exception. In the most recent version of Web API 2.0 I could call Request.HttpContent.ReadAsStringAsync()inside my request logger, and the body would still arrive to the controller in tact. How can I rewind the stream after reading it? or How can I read the request body without consuming it? public class RequestLoggerMiddleware : OwinMiddleware { public RequestLoggerMiddleware(OwinMiddleware next) : base(next) { } public override Task Invoke(IOwinContext context) { return Task.Run(() => { string body = new StreamReader(context.Request.Body).ReadToEnd(); // log body context.Request.Body.Position = 0; // cannot set stream position back to 0 Console.WriteLine(context.Request.Body.CanSeek); // prints false this.Next.Invoke(context); }); } } public class SampleController : ApiController { public void Post(ModelClass body) { // body is now null if the middleware reads it } }

  • Asset Pipeline acting up

    - by Abram
    Ok, so my asset pipeline has suddenly started acting up on my development machine. JS functions that previously worked are now throwing "not a function" errors.. I know I must be doing something wrong. A minute ago the datatables jquery function was working, then it was throwing an error, then it was working, and now it's not working or throwing an error. Here is my application.js //= require jquery //= require jquery-ui //= require jquery_ujs //= require_self //= require_tree . //= require dataTables/jquery.dataTables //= require dataTables/jquery.dataTables.bootstrap //= require bootstrap //= require bootstrap-tooltip //= require bootstrap-popover //= require bootstrap-tab //= require bootstrap-modal //= require bootstrap-alert //= require bootstrap-dropdown //= require jquery.ui.addresspicker //= require raty //= require jquery.alphanumeric //= require jquery.formrestrict //= require select2 //= require chosen/chosen.jquery //= require highcharts //= require jquery.lazyload Here is some of my layout header: <%= stylesheet_link_tag "application", media: "all" %> <%= yield(:scripthead) %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %> <%= yield(:head) %> Above I am using the yield to load up online scripts from google as they're only needed on some pages, and generally slow down the site if included in the application layout. I tried removing the yield but things were still broken, even after clearing the browser cache and running rake assets:clean (just to be on the safe side). Here's what shows up between CSS and metatags (for a page with nothin in the yield scripthead): <script src="/assets/jquery.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui.js?body=1" type="text/javascript"></script> <script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script> <script src="/assets/application.js?body=1" type="text/javascript"></script> <script src="/assets/aidmodels.js?body=1" type="text/javascript"></script> <script src="/assets/audio.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-alert.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-dropdown.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-modal.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-popover.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tab.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tooltip.js?body=1" type="text/javascript"></script> <script src="/assets/branches.js?body=1" type="text/javascript"></script> <script src="/assets/charts.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/backup_chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/consumers.js?body=1" type="text/javascript"></script> <script src="/assets/dispensers.js?body=1" type="text/javascript"></script> <script src="/assets/favorites.js?body=1" type="text/javascript"></script> <script src="/assets/features.js?body=1" type="text/javascript"></script> <script src="/assets/generic_styles.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.base.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.bing.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.googlemaps.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.mapquest.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.openlayers.js?body=1" type="text/javascript"></script> <script src="/assets/highcharts.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui-1.8.18.custom.min.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.alphanumeric.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.formrestrict.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.lazyload.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.ui.addresspicker.js?body=1" type="text/javascript"></script> <script src="/assets/likes.js?body=1" type="text/javascript"></script> <script src="/assets/messages.js?body=1" type="text/javascript"></script> <script src="/assets/overalls.js?body=1" type="text/javascript"></script> <script src="/assets/pages.js?body=1" type="text/javascript"></script> <script src="/assets/questions.js?body=1" type="text/javascript"></script> <script src="/assets/raty.js?body=1" type="text/javascript"></script> <script src="/assets/reviews.js?body=1" type="text/javascript"></script> <script src="/assets/sessions.js?body=1" type="text/javascript"></script> <script src="/assets/styles.js?body=1" type="text/javascript"></script> <script src="/assets/tickets.js?body=1" type="text/javascript"></script> <script src="/assets/universities.js?body=1" type="text/javascript"></script> <script src="/assets/users.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-transition.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-affix.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-button.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-carousel.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-collapse.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-scrollspy.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-typeahead.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/select2.js?body=1" type="text/javascript"></script> From application.rb: config.assets.initialize_on_precompile = false # Enable the asset pipeline config.assets.enabled = true config.action_controller.assets_dir = "#{File.dirname(File.dirname(__FILE__))}/public" # Version of your assets, change this if you want to expire all your assets config.assets.version = '1.0' I'm sorry, I'm not sure what else to include to help with this puzzle, but any advise would be appreciated. I was having no problems before I started trying to upload to heroku and now everything's gone haywire. EDIT: In the console at the moment I'm seeing Uncaught TypeError: Cannot read property 'Constructor' of undefined bootstrap-popover.js:33 Uncaught ReferenceError: google is not defined jquery.ui.addresspicker.js:25 Uncaught TypeError: Object [object Object] has no method 'popover' overall:476
