  • LibGdx efficient data saving/loading?

    - by grimrader22
    Currently, my LibGDX game consists of a 512 x 512 map of Tiles and entities such as players and monsters. I am wondering how to efficiently save and load the data of my levels. At the moment I am using JSON serialization for each class I want to save. I implement the Json.Serializable interface for all of these classes and write only the variables that are necessary. So my map consists of 512 x 512 tiles, that's 260,000 tiles. Each tile on the map consists of a Tile object, which points to some final Tile object like a GRASS_TILE or a STONE_TILE. When I serialize each level tile, the final Tile that it points to is re-serialized over and over again, so if I have 100 Tiles all pointing to GRASS_TILE, the data of GRASS_TILE is written 100 times over. When I go to load/deserialize my objects, 100 GrassTile objects are created, but they are each their own object. They no longer point to the final tile object. I feel like this reading/writing files very slow. If I were to abandon JSON serialization, to my knowledge my next best option would be saving the level data to a sql database. Unless there is a way to speed up serializing/deserializing 260,000 tiles I may have to do this. Is this a good idea? Could I really write that many tiles to the database efficiently? To sum all this up, I am trying to save my levels using JSON serialization, but it is VERY slow. What other options do I have for saving the data of so many tiles. I also must note that the JSON serialization is not slow on a PC, it is only VERY slow on a mobile device. Since file writing/reading is so slow on mobile devices, what can I do?

  • A certain flash application causes a system crash

    - by noobermin
    It's no surprise I guess. Go here to try it! http://www.belgeler.com/blg/2hni/griffiths-introduction-to-electrodynamics-3-ed-solutions-manual It's wonderful, after a few seconds, top shows that our good friend plugin-container takes 83% of the physical memory (8 GB) before everything freezes and the PC doesn't respond. I'm using Ubuntu 12.04 and I have an nvidia (GTS 250) card with the "post-release updates" version of the driver. OFFTOPIC: Yes, it's the solutions manual. I'm self-studying so I don't have a professor to check my work. Please don't judge me :)

  • Building a Store Locator ASP.NET Application Using Google Maps API (Part 1)

    Over the past couple of months I've been working on a couple of projects that have used the free <a href="http://code.google.com/apis/maps/">Google Maps API</a> to add interactive maps and <a href="http://en.wikipedia.org/wiki/Geocoding">geocoding</a> capabilities to ASP.NET websites. In a nutshell, the Google Maps API allow you to display maps on your website, to add markers onto the map, and to compute the latitude and longitude of an address, among many other tasks.With some Google Maps API experience under my belt, I decided it would be fun to implement a store locator feature and share it here on 4Guys. A store locator lets a visitor enter an address or postal code and then shows the nearby stores. Typically, store locators display the

  • How do I make my rain effect look more like rain and less like snowfall?

    - by Nikhil Lamba
    I am making a game in that game I want a rain effect. I am little bit far from this right now. I am creating the rain effect like below: particleSystem.addParticleInitializer(new ColorInitializer(1, 1, 1)); particleSystem.addParticleInitializer(new AlphaInitializer(0)); particleSystem.setBlendFunction(GL10.GL_SRC_ALPHA, GL10.GL_ONE); particleSystem.addParticleInitializer(new VelocityInitializer(2, 2, 20, 10)); particleSystem.addParticleInitializer(new RotationInitializer(0.0f, 30.0f)); particleSystem.addParticleModifier(new ScaleModifier(1.0f, 2.0f, 0, 150)); particleSystem.addParticleModifier(new ColorModifier(1, 1, 1, 1f, 1, 1, 1, 3)); particleSystem.addParticleModifier(new ColorModifier(1, 1, 1f, 1, 1, 1, 1, 6)); particleSystem.addParticleModifier(new AlphaModifier(0, 1, 0, 3)); particleSystem.addParticleModifier(new AlphaModifier(1, 0, 1, 125)); particleSystem.addParticleModifier(new ExpireModifier(50, 50)); scene.attachChild(particleSystem); But it looks like snowfall! What changes can I do for it to look more like rain? EDIT Here is a screenshot:

  • How to import Evolution application data from home folder backup

    - by Wolter Hellmund
    I had many folders and filters and mail in general in Evolution on my previous Ubuntu install, which I thought would be available for me for I had backed up my home directory. I have copied now Evolution related folders to my new home directory, and Evolution is not showing either the folders I had or any of the filters. To be more precise, I have copied the mail folder to ~/.config/evolution/ but that hasn't changed anything, as I said.

  • Switching my collision detection to array lists caused it to stop working

    - by Charlton Santana
    I have made a collision detection system which worked when I did not use array list and block generation. It is weird why it's not working but here's the code, and if anyone could help I would be very grateful :) The first code if the block generation. private static final List<Block> BLOCKS = new ArrayList<Block>(); Random rnd = new Random(System.currentTimeMillis()); int randomx = 400; int randomy = 400; int blocknum = 100; String Title = "blocktitle" + blocknum; private Block block; public void generateBlocks(){ if(blocknum > 0){ int offset = rnd.nextInt(250) + 100; //500 is the maximum offset, this is a constant randomx += offset;//ofset will be between 100 and 400 int randomyoff = rnd.nextInt(80); //500 is the maximum offset, this is a constant randomy = platformheighttwo - 6 - randomyoff;//ofset will be between 100 and 400 block = new Block(BitmapFactory.decodeResource(getResources(), R.drawable.block2), randomx, randomy); BLOCKS.add(block); blocknum -= 1; } The second is where the collision detection takes place note: the block.draw(canvas); works perfectly. It's the blocks that don't work. for(Block block : BLOCKS) { block.draw(canvas); if (sprite.bottomrx < block.bottomrx && sprite.bottomrx > block.bottomlx && sprite.bottomry < block.bottommy && sprite.bottomry > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } // bottom left touching block? if (sprite.bottomlx < block.bottomrx && sprite.bottomlx > block.bottomlx && sprite.bottomly < block.bottommy && sprite.bottomly > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } // top right touching block? if (sprite.toprx < block.bottomrx && sprite.toprx > block.bottomlx && sprite.topry < block.bottommy && sprite.topry > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } //top left touching block? if (sprite.toprx < block.bottomrx && sprite.toprx > block.bottomlx && sprite.topry < block.bottommy && sprite.topry > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } } The values eg bottomrx are in the block.java file..

  • How to approach big developer companies if I have a killer game idea? (for mobile devices)

    - by Balázs Dávid
    I have an idea for a game that has a potential, but I'm not a programmer. How to tell this to development companies without being my idea stolen? All I want from the company is first to watch a 3-minute long video presentation about my idea and if they see fantasy in it then we can talk about the details. I have already sent an e-mail to several big companies that have the expertise needed to code the game, they haven't answer me. Actually the idea is nothing fancy, no 3D, but fun and unique.
