  • Push back rectangle where collision happens

    - by Tifa
    I have a tile collision on a game I am creating but the problem is once a collision happens for example a collision happens in right side my sprite cant move to up and bottom :( thats because i set the speed to 0. I thinks its wrong. here is my code: int startX, startY, endX, endY; float pushx = 0,pushy = 0; // move player if(Gdx.input.isKeyPressed(Input.Keys.LEFT)){ dx=-1; currentWalk = leftWalk; } if(Gdx.input.isKeyPressed(Input.Keys.RIGHT)){ dx=1; currentWalk = rightWalk; } if(Gdx.input.isKeyPressed(Input.Keys.DOWN)){ dy=-1; currentWalk = downWalk; } if(Gdx.input.isKeyPressed(Input.Keys.UP)){ dy=1; currentWalk = upWalk; } sr.setProjectionMatrix(camera.combined); sr.begin(ShapeRenderer.ShapeType.Line); Rectangle koalaRect = rectPool.obtain(); koalaRect.set(player.getX(), player.getY(), pw, ph /2 ); float oldX = player.getX(), oldY = player.getY(); // THIS LINE WAS ADDED player.setXY(player.getX() + dx * Gdx.graphics.getDeltaTime() * 4f, player.getY() + dy * Gdx.graphics.getDeltaTime() * 4f); // THIS LINE WAS MOVED HERE FROM DOWN BELOW if(dx> 0) { startX = endX = (int)(player.getX() + pw); } else { startX = endX = (int)(player.getX() ); } startY = (int)(player.getY()); endY = (int)(player.getY() + ph); getTiles(startX, startY, endX, endY, tiles); for(Rectangle tile: tiles) { sr.rect(tile.x,tile.y,tile.getWidth(),tile.getHeight()); if(koalaRect.overlaps(tile)) { //dx = 0; player.setX(oldX); // THIS LINE CHANGED Gdx.app.log("x","hit " + player.getX() + " " + oldX); break; } } if(dy > 0) { startY = endY = (int)(player.getY() + ph ); } else { startY = endY = (int)(player.getY() ); } startX = (int)(player.getX()); endX = (int)(player.getX() + pw); getTiles(startX, startY, endX, endY, tiles); for(Rectangle tile: tiles) { if(koalaRect.overlaps(tile)) { //dy = 0; player.setY(oldY); // THIS LINE CHANGED //Gdx.app.log("y","hit" + player.getY() + " " + oldY); break; } } sr.rect(koalaRect.x,koalaRect.y,koalaRect.getWidth(),koalaRect.getHeight() / 2); sr.setColor(Color.GREEN); sr.end(); I want to push back the sprite when a collision happens but i have no idea how :D pls help

  • Why wont Ubuntu recognize Rogers LTE Rocket stick 330U Sierra wireless modem?

    - by rob lawson
    I tried to plug the rocket stick into the USB slot, and Ubuntu does not recognize that there is anything in the drive. I plug in a standard USB thumbdrive and it is recognized right away. Are there any applications to help me open the rogers folders to see the files, and maybe connect to the Internet using said rocket stick 330U? I've been searching for this answer for almost a week now, seems no one knows how to get the net using this piece of technology.

  • Box2D Bicycle Wheels Motor Problem - Flash 2.1a

    - by Craig
    I have made a bicycle with Box2D using several polygons for the frame at different angles connected using weld joints, and I have revolute joints on the wheels with a motor. I have made some basic terrain (straight ground and a small ramp) and added keyboard input to control the bicycle with torque to balance it. All of this is done in with Box2D's Debug Draw. When the bicycle is on its back wheel but diagonally forward (kinda like this position - /) the motors just cause it go spinning backwards over when in reality it should either stay on its back wheel or go down onto both wheels. Here's my code the revolute joints: //Front Wheel Joint var frontWheelJointDef:b2RevoluteJointDef = new b2RevoluteJointDef(); frontWheelJointDef.Initialize(frontWheelBody, secondFrameBody, frontWheelBody.GetWorldCenter()); frontWheelJointDef.enableMotor=true; frontWheelJointDef.maxMotorTorque=10000; frontWheelJoint = _world.CreateJoint(frontWheelJointDef) as b2RevoluteJoint; //Rear Wheel Joint var rearWheelJointDef:b2RevoluteJointDef = new b2RevoluteJointDef(); rearWheelJointDef.Initialize(rearWheelBody, firstFrameBody, rearWheelBody.GetWorldCenter()); rearWheelJointDef.enableMotor=true; rearWheelJointDef.maxMotorTorque=10000; rearWheelJoint = _world.CreateJoint(rearWheelJointDef) as b2RevoluteJoint; And here's the relevant part of my update function: // up and down control wheels motor if (up) { motorSpeed-=0.5; } if (down) { motorSpeed += 0.5; } // left and right control cart torque if (left) { middleCentreFrameBody.ApplyTorque( -3); gearBody.ApplyTorque( -3); firstFrameBody.ApplyTorque( -3); secondFrameBody.ApplyTorque( -3); rearWheelToChainBody.ApplyTorque( -3); chainToFrontFrameBody.ApplyTorque( -3); topMiddleFrameBody.ApplyTorque( -3); } if (right) { middleCentreFrameBody.ApplyTorque( 3); gearBody.ApplyTorque( 3); firstFrameBody.ApplyTorque( 3); secondFrameBody.ApplyTorque( 3); rearWheelToChainBody.ApplyTorque( 3); chainToFrontFrameBody.ApplyTorque( 3); topMiddleFrameBody.ApplyTorque( 3); } // motor friction motorSpeed*=0.99; // motor max speed if (motorSpeed>100) { motorSpeed=100; } rearWheelJoint.SetMotorSpeed(motorSpeed); frontWheelJoint.SetMotorSpeed(motorSpeed); Any ideas what might be causing this? Thanks

  • SPSS launcher for Unity

    - by user67157
    I have "SPSS 20 for Linux" statistical analysis program installed under /opt/IBM directory. I can run it via terminal entering the command line with /opt/IBM, and it runs without any problems. When the program window opens, I go to the launcher and right-click on its icon to lock it there, but after closing it, the icon becomes useless. When I click on it, nothing happens. I tried to ceate a launcher for it, but there is no use again.

  • adding custom SSIS transformation to visual studio toolbox fails

    - by ryangaraygay
    Just very recently I encountered an issue in deploying a custom SSIS component assembly which turns out to be a relative "no-brainer" error if only the clues were more straightforward. Basically after deploying the assembly I could not find my component listed in the "SSIS Data Flow Items" tab list.It turns out that the assembly containing the component just had missing or referenced the incorrect assemblies.I have outlined the steps I took that guided me on the right direction on this blog post of mine : adding custom SSIS transformation to visual studio toolbox fails

In my opinion, Apple's iOS has changed everything in Mobile BI.  Yes Blackberry, Android and Symbian and all the rest have their place in the market but I believe that increasingly consumers (not IT departments) influence BI decision making processes.  Consumers are choosing the iPhone and the iPad. The number of iPads I see in business meetings now is staggering.  Some use it for email and note taking and others are starting to use corporate applications.  The possibilities for Mobile BI are countless and I would expect to see iPads enterprise-wide over the next few years.   These new devices will provide just-in-time access to critical business information.  Front-line managers interacting with customers, suppliers, patients or citizens will have information literally at their fingertips. I've experimented with several mobile BI tools.  They look cool but like their Executive Information System (EIS) predecessors of the 1990's these tools lack a backbone and a plausible integration strategy.  EIS was a viral technology in the early 1990's.  Executives from every industry and job function were showcasing their dashboards to fellow co-workers and colleagues at the country club.  Just like the iPad, every senior manager wanted one.  EIS wasn't a device however, it was a software application.   EIS quickly faded into the software sunset as it lacked integration with corporate information systems.  BI servers  replaced EIS because the technology focused on the heavy data lifting of integrating, normalizing, aggregating and managing large, complex data volumes.  The devices are here to stay. The cute stand-alone mobile BI tools, not so much. If all you're looking to do is put Excel files on your iPad, there are plenty of free tools on the market.  You'll look cool at your next management meeting but after a few weeks, the cool factor will fade away and you'll be wondering how you will ever maintain it.  If however you want secure, consistent, reliable information on your iPad, you need an integration strategy and a way to model the data.  BI Server technologies like the Oracle BI Foundation is a market leading approach to tackle that issue. I liken the BI mobility frenzy to buying classic cars.  Classic Cars have two buying groups - teenagers and middle-age folks looking to tinker.  Teenagers look at the pin-stripes and the paint job while middle-agers (like me)  kick the tires a bit and look under the hood to check out the quality and reliability of the engine.  Mobile BI tools sure look sexy but don't go very far without an engine and a transmission or an integration strategy. The strategic question in Mobile BI is can these startups build a motor and transmission faster than Oracle can re-paint the car?  Oracle has a great engine and a transmission that connects to all enterprise information assets.  We're working on the new paint job and are excited about the possibilities.  Just as vertical integration worked in the automotive business, it too works in the technology industry.

  • Creating predefinied camera views - How do I move the camera to make sense while using Controller?

    - by Deukalion
    I'm trying to understand 3D but the one thing I can't seem to understand is the Camera. Right now I'm rendering four 3D Cubes with textures and I set the Project Matrix: public BasicCamera3D(float fieldOfView, float aspectRatio, float clipStart, float clipEnd, Vector3 cameraPosition, Vector3 cameraLookAt) { projection_fieldOfView = MathHelper.ToRadians(fieldOfView); projection_aspectRatio = aspectRatio; projection_clipstart = clipStart; projection_clipend = clipEnd; matrix_projection = Matrix.CreatePerspectiveFieldOfView(projection_fieldOfView, aspectRatio, clipStart, clipEnd); view_cameraposition = cameraPosition; view_cameralookat = cameraLookAt; matrix_view = Matrix.CreateLookAt(cameraPosition, cameraLookAt, Vector3.Up); } BasicCamera3D gameCamera = new BasicCamera3D(45f, GraphicsDevice.Viewport.AspectRatio, 1.0f, 1000f, new Vector3(0, 0, 8), new Vector3(0, 0, 0)); This creates a sort of "Top-Down" camera, with 8 (still don't get the unit type here - it's not pixels I guess?) But, if I try to position the camera at the side to make "Side-View" or "Reverse Side View" camera, the camera is rotating to much until it's turned around it a couple of times. I render the boxes at: new Vector3(-1, 0, 0) new Vector3(0, 0, 0) new Vector3(1, 0, 0) new Vector3(1, 0, 1) and with the Top-Down camera it shows good, but I don't get how I can make the camera show the side or 45 degrees from top (Like 3rd person action games) because the logic doesn't make sense. Also, since every object you render needs a new BasicEffect with a new projection/view/world - can you still use the "same" camera always so you don't have to create a new View/Matrix and such for each object. It's seems weird. If someone could help me get the camera to navigate around my objects "naturally" so I can be able to set a few predtermined views to choose from it would be really helpful. Are there some sort of algorithm to calculate the view for this and perhaps not simply one value? Examples: Top-Down-View: I have an object at 0, 0, 0 when I turn the right stick on the Xbox 360 Controller it should rotate around that object kind of, not flip and turn upside down, disappear and then magically appear as a tiny dot somewhere I have no clue where it is like it feels like it does now. Side-View: I have an object at 0, 0, 0 when I rotate to sides or up and down, the camera should be able to show a little more of the periphery to each side (depending on which you look at), and the same while moving up or down.

    Well, I have some problems with procrastination and whatnot, but those get infinitely worse, when I cannot remember what I should be doing.

How I get back on track? (because right now my technique of opening the source code and staring at it is not working)

  • Interview with Koen Aben, Supply Chain Director of WE Fashion

    - by user801960
    We recently spoke to Koen Aben, the Supply Chain Director of WE Fashion, who gave us some insight into how Oracle supported the international fashion retailer through the completion of a large scale integration project across its 340 European stores. Koen explains the reasoning behind the project which was to create a common retail foundation and to integrate and align working processes to drive insight and enable continued growth. It is always good to hear from someone of Koen’s experience who can articulate the benefits of partnering with the right company for such an extensive project as this. Koen explains that a crucial element of such a project is to unify business applications into a common platform, adding that for successful growth, retailers really need to achieve enterprise-wide alignment. At the start of the three year project, WE Fashion’s application platform was fragmented impacting the company’s ability to support sustained growth. In light of this, WE Fashion invested in its processes, systems, teams and partnerships to build the needed retail foundation. Now after successfully completing the project, the basis is in place to ensure that growth is unimpeded. In the video, Koen Aben highlights some of the factors necessary for the success of the project as: Having an understanding that the process of creating a growth platform for a company is a long journey Accepting that during a lengthy project such as this, there will be high and low points experienced within the project team and the business, but that the relationship with your partners is crucial to the success of the project. Having the correct team in place will prove to be the “lynch –pin” of any successful project Oracle supported Koen and his team in implementing this project, and is recognised for the role it played during this development in partnership with the company. On his experience with working with the Oracle team, Koen points out that in the critical situations, Oracle was there to ensure that the right people were in place whenever needed and this was key to ensuring the project’s success. Since Oracle is one of the few providers that can offer an enterprise-wide retail platform, our best practice approach is key to connecting interactions throughout the business to enable insight and optimise operations. This is a great example of a large scale international retail project, where the true success of its completion is reflected in how proud the company is about what has been achieved, and the fact that results are already being seen.
