    Re: Website Issues…?


    Hope your business is doing great this year.

    I was doing some industry benchmarking for a client of mine when I came across your website.

    I noticed a few technical errors which correspond with a drop of website traffic over the last 6-8 months which I thought I would bring to your attention.

    I was analyzing your site and it seems that some of your website rankings have dropped. It is due to non optimized techniques/errors And Google guidelines not being followed properly.

    Your web page failed on 4 high priority checks: Meta Description, Headings Status, Broken Links Test, URL Canonicalization Test

    Your most common keywords are not appearing in one or more of the meta-tags above. Your primary keywords should appear in your Meta.

    Site link diversity and Domain Authority is low

    URL Canonicalization should resolve to the same URL, but currently do not.

    5 of them are missing the required ‘alt’ attribute.

    Your website should load quicker

    Your webpage has so many ‘img’ tags and 5 of them are missing the required ‘alt’ attribute.

    Your page has more than 20 http requests, which can slow down page loading.

    I would love the chance to help as well however; this report will at least give you a gauge on the quality of what I do. If you are interested then please share your requirement and contact details.
    Please let me know if we can discuss this.

  10. Kris Rodgerson

    Hi there my name is Kris and I am a digital marketer. I help my clients sites bring in more traffic by helping their site become the most authoritative to the search engines. Everyone tries to tell you that they will get you on the first page of google next week. Most of the time they are just telling you what you want to hear, but some can actually do it. The only problem is that the tactics they would perform on your site will get on the top of Google quickly but will also eventually get you a penalty from Google as well. Once you have a penalty from Google it is extremely difficult to get on top the search engines ever again.

    I tell you this to be upfront and straight with you. We are looking for long term realsonship with clients and do not wish to tell you what you want to hear. We focus on delivering data driven results to our clients so they really know what is going on and how well they are performing.

    Currently I am offering a free consultation where I will take a look at your site and also at your competitors with you and see what needs to happen to get you to where you want to go. I just want to know if you would be interested in this free consultation.

    The consultation is completely free and there is not any pressure or strings attached or tricksto make you use my services. My thinking is pretty straight forward, I provide a lot of value with these consultations and I know that some will not use my services in the end, which is ok. Others will need my help and wish to use my services. Either way I am always happy to help other business owners understand the changing world of online marketing and how they can beat their competitors.

    Let me know the best number to reach you at and I will be in touch and take a look at your site and your competitors and then provide you with my findings.

    Let me know if you have any questions.

    Hi, Oskar Veerhoek, i am trying to compile one of your project at GitHub named episode_34 / PerPixelLighting. i am facing the following problem in eclipse. res\models\bunny.obj (The system cannot find the path specified)
    at Method)
    at Source)
    at Source)
    at utility.OBJLoader.loadModel(
    at PerPixelLightingDemo.setUpVBOs(
    at PerPixelLightingDemo.main(

    Probably the following files are missing……….MODEL_LOCATION = “res/models/bunny.obj”;
    private static final String VERTEX_SHADER_PER_PIXEL_LIGHTING_LOCATION = “res/shaders/pixel_phong_lighting.vs”;
    private static final String VERTEX_SHADER_PER_VERTEX_LIGHTING_LOCATION = “res/shaders/vertex_phong_lighting.vs”;

    private static final String FRAGMENT_SHADER_PER_VERTEX_LIGHTING_LOCATION = “res/shaders/vertex_phong_lighting.fs”;

    Can you please give me access to the files named bunny.obj, pixel_phong_lighting.vs, res/shaders/vertex_phong_lighting.vs, res/shaders/pixel_phong_lighting.fs, res/shaders/vertex_phong_lighting.fs. I am learning lwjgl. It would be of great help. Please reply at your earliest convenience.

  19. Sandspro

    Hello. I have scene some of your tutorials, and I have been experimenting with your obj rendering code. I have run into some serious problems with it encountering odd rendering glitches that cause the model to render odd, although it looks find in blender. I was wondering if you could help me solve the problem as it is really annoying to see a face missing or rendered odd. If you need the model or code, just email me. ~sandspro

    1. Sandspro

      Nevermind, I have figured out the issues on my own. It was really in the use of culling the faces and depth testing which was causing some faces to not show up or be completely transparent from certain angles.

    Hello Oskar!
    Your videos are helping me so much to learn about LWJGL! I am also just 14, and your videos help me to become better at programming like you. I am working on a project similar to minecraft, but I am trying to make it better, and I have been researching on terrain generation for ages… Thanks for all the awesome tuts!

  21. Eric

    Oskar – Thanks for the great tutorials! Thanks to your 2d Minecraft tutorial, I’ve been able to build a simple 2d map editor for a tile based side-scroller I’ve been working on. I’d like to take the map editor to the next level, but I’m struggling with building text box input that will take text from the user (me) display it on the screen and save to my map xml file. lwjgl input works great for controls, but not so good getting text from user. I tried to get Nifty-Gui and TWL up and running, but quickly became frustrated. Have you ever worked with either? Is there another option for simple gui menu/text boxes that can be implemented with lwjgl?

    Thanks again!


    1. Oskar Veerhoek Post author

      You’re welcome!
      As far as I know NiftyGUI and TWL are the best choices for GUI development. You could try creating your own, but I find that to be an unnecessary pain. I have worked a bit with NiftyGUI.

        Hello, I thought you’d like to know that you mispelled the word “alot” on your website. I’ve had similar mistakes on my site that keep cropping up so I now use a site like to keep them off. -Scott

  22. Paul

    Love 3D tutorials! This is a big void for independent developers! Would love to see tutorials on topics as creating a terrain and importing a model that is already textured from from a 3D program (maybe as an advanced series). Above all, KEEP UP THE GOOD WORK!!! :)

    1. Oskar Veerhoek Post author

      Thanks! The problem with these 3D things is that they are very difficult to teach. I will, however, most certainly delve into them at one point or another.

    Hello there,

    I have been checking out a lot of your video’s lately as I am wanting to learn Java for games development. Your tutorials are good, but fast passed and hard to keep up with. I was wondering what serious advice you would give someone wanting to learn this programming language?

    I have a hard time teaching myself how to write Java, but understand how many of Java’s Operators, Statements and Variables work.

    I can develop websites using HTML and CSS which were rather easy languages to learn. I approached Java with the same aptitude, only to be disappointed in myself :(

    It is difficult to explain, I can look at the source of a Java project and know what it basically does. But I cannot for life of me write lines of code that work! It is just how my brain works. I believe that having a reliable source is the way forward, someone who is there to answer questions and help when an issue comes into play when said person is available to do so.

    The main question is: How in the hell did you learn so quickly and manage to write Java programs so fluently? I am very much jealous of your talent 😉

    Any help would be greatly appreciated.
    (I have books, they help somewhat. But as you may know, reading is rather boring and causes me to lose interest & self confidence.)

    Kind regards,

    – Dean

  24. John


    If you haven’t guessed (by the greeting), I’m in Australia – I’ve been developing plugins for a minecraft server software called ‘bukkit’ for a while now, all the plugins are written in Java. Was loving java, and wanted to learn a bit more about the subject of Game Development using LWJGL – Found these videos very useful for getting started! I just want to say thanks very much! I’m about to move onto C++ – I’ve coded in about 15 languages over the years and only very, very briefly touched C++ (not much beyond the stage of “Hello World…”), and I am using your vids! I would also like to thankyou of taking the foresight of translating all your vids into text – I only get 6GB of inet a month, and I don’t want to use it up too quickly.

    So, once again, thanks again, and I’ll let you know how I get on.


    One more note – I’m also 14 xP
