I haven’t posted quite some time so I will post a small update.

On 10th of May I celebrated my 19th birthday. Yeah I am that young/old for those who didn’t know. It was more or less just a normal day with extra chocolates coming in my way.

Not my cake obviously.

I’m currently working on finishing the new course. I decided that I will scrap SDL in favor to SFML which is easier to teach to beginners. So I had to redo everything I had with SFML. I’m using the new 2.0 version. My deadline is somewhere this week and then I will release it to the public. I will still add additional videos once it is online but first I want to publish it when I have the main parts done. I hope that people will like it. I’ll post it here once it is online.

Well as most of you may know it’s May 15th and the Diablo 3 box is standing here on my desk. This is going to take quite some time from me but I hope that I will be able to work on things as normal :) If anyone following my blog is also playing D3, then fell free to contact me in any way and we can play together.

Now back to slaying some monsters, also expect more updates soon.

I will try to be short in this post. As I said before I’m working on the documentation as always. I have to finish it this weekend so I hope that I won’t have to mention in again. I hate it.

The two new games are Deep Green and Vuzball!. Vuzball is a game I made in a day and now I’m just adding some final touches so that it’s fun to play. It’s a simple clone of another game and it was just something I did for fun.

I already posted the code on GitHub. It’s a quite ugly code so don’t expect much from it.

The other project is Deep Green. It’s a game that I have worked on some time ago and I decided to finish it. I ported the whole thing from the old quick code to my box2d “framework” and now it works even better. I’ll try to make something out of this one but you never know.

So that’s about it for this post. Now off to work on the documentation.

A year has passed and we have visited our capital city to participate in the programming tournament again.

The tournament was held on Saturday in Ljubljana at the institute of Jožef Štefan (IJS). Our school organized the trip and we arrived there sometime in the morning. The competition started at 10 AM till 1 PM. There ware 4 groups as always: 3 difficulty stages where you had to solve tasks with programming and 1 group where you had to build a website.

I joined the 2nd group of programmers. It isn’t the hardest one but we didn’t have any real preparations for the tournament so it was better that I went into the 2nd group. We had to solve 5 problems using any of the more known languages (C,C++, Python, Java, C#, …). The website team had to build a pong game out of basic HTML using divs and JavaScript.

After the competition ended we had to wait till later for the results. A few talks were held to shorten the wait time.

The results (Slovenian link) were in and I was 4th with 86 points out of 100. I’m really happy with that. I won an 60 GB SSD drive and I plan to switch my OS drive today. A friend of mine (Vito Meznarič (Slovenian blog)) was 1st in website development.

I would call that a successful day.

In other news: I made a new video log few days ago and haven’t posted it here yet. Sometime it takes some days for me to post…

For those who are not in the mood to watch the video, here is a picture of the current state of my small Box2D framework.

I added collision sensors, filtering and ignoring into it. Most of the framework is done I only have to fix some rendering things and maybe add joins but I don’t think that I will need them so I probably won’t add them yet.

And that is all for this post.

Hello, I haven’t posted for quite some time now so I think it’s time that I update the situation.

First let’s go through what I have been working on for the past 2 weeks. Well one of the bigger changes is that I started learning playing the guitar. Yeah, I got myself a guitar and now I spend at least an hour a day practicing. When I started last week I was practicing even more so I didn’t put much time into other things. But now I just settled on a “fixed” schedule so I can work on other things. I hope I’ll stick with it because I really want to learn it.

I also finished my school project “School Jumper”. I released it for my school class for testing and already made a new version fixing some bugs. I also found a mistake that I was doing from the day I started with OpenGL. I thought that using images for textures with a resolution different than the power of 2 was totally OK. But as testing showed it was not. Some graphics cards did not support those texture resolution and the result was that the users only saw white squares. This is a problem that appeared already in Squared Shooter and every other game that came after it. Back then I thought that it was a driver problem but now I know that it isn’t. So from now on I’ll only stick to the default (16, 32, 64, 128, 256, 512, …) resolutions.

“School Jumper” isn’t really interesting. I was getting bored with it early but it had to be done. But it’s a small little time waster. I’ll wait some time before I release it here because some changes might happen but it probably won’t take long. I’ll also make a Linux port when I will find the time. I will release the source code after my project it graded so it will be free to use. Expect the source code around end of May or something like that.

The main focus currently is on the “documentation” of the game/project. I have to write it and post it till April 14th and I still have a lot to do. It’s a pain to write it but it has to be done.

The other big thing currently is working on the new project. I’m learning Box2D for it and I’m writing myself a really small framework for easy creation and handling of complex shapes and things like that. I still have to look up some things but Box2D is really an awesome framework. But it also changes the way you handle moving, collision and rendering so it takes some time to getting used to it. I also switched from orthographic OpenGL to normal OpenGL so everything is a little different now and takes time to properly understand it.

And that is all for now. I also haven’t made any new videos so I will try to make an interesting test with Box2D and make a video with it so that you can see what it looks like. Maybe even today, but who knows.

No fancy post names. It is what it is: a new video log!

Well it does look like I missed the Wednesday upload date but now it’s here. I’m kind of lazy these days and don’t work that much. Who knows why. I’m probably in some creative block state or in super lazy mode. I’ll try to change that as soon as possible.

I just show the projects I have been working on these days. The game is almost finished. I implemented the instructions screen while the video was uploading which leaves just the levels. I’ll try to make the game at least 20-30 levels long so that it has some play time (more than 10 minutes). The OpenGL demo might seam silly for some, but I never really got into true 3D with perspectives, triangles only, no orthos and some silly lighting. Also as I said don’t expect 3D games.

Now that the game is almost finished and I’ll start writing the documentation. I hope that won’t kill me because I hate writing it. I’ll also start recording new videos for the course so that I can get it public in a month or so.

And that is all for this post.

And I am back. If you haven’t noticed I was kind of away last week. We had holidays and I totally took that time to take a break. Even if I planned other things.

A quick week

The week passed really quickly. I planned to finish the project during the holidays and maybe start on something else but it turned out I took a full vacation from everything. I also wasn’t home a few days so that makes even less time to work. So let’s just say that nothing was done that week even though I have learned some new OpenGL things but that doesn’t really count.

It’s Wednesday again and it seams that a new log will come out today. They more or less look like a weekly thing (being released every Wednesday) and if I am fine if I will keep it that way.

So that’s all the update for this post. Expect a new video soon.

And it has been a somewhat busy one.

The project: SM

The game is nearing completion. The level editor and the actual game is complete. The only thing missing is the menu, which should not be a big problem, an end game and saving the players progress. I also have to add some sound effects and some background music. And then it’s done. So that is all together about 1 or 2 days of work, few hours each.

As I said in the video I had to revamp some things I used from my framework. As I told before I’m not using my whole framework for this project only some small functions. The cause is because I would need to document then everything and that is something I don’t want to do. I fixed the font rendering system because it was working really slow. That’s because I was using texture fonts. Now that I switched to pixmap fonts it works much much faster.

I will add the changes to the framework when this game is done. I will probably add the animation system I’m currently using. But I don’t want to work on the framework currently so that will only be a small fix.

I have holidays next week and I hope that I will find the time to create videos for the course I’m working too. Now that this project is nearing completion I want to focus on the next one.

So here is a song for next week:

Have a nice day.

Not a really interesting post title but I'll let it be because it’s the first video log I created.

I had a sports “accident” on Saturday so I wasn’t really able to go anywhere which would have been a perfect opportunity for game development but I just suckered in and played Resident Evil 4 on my Wii again. Oh well.

But the “School Madness” project is going nicely. I added platforming and all with double jump. There is still lots of work but I’m getting there.

While recording the video I noticed that the player didn’t jump as high as normal. The game did run at 10-20 fps but I’m using delta time for everything so that should not happen. It works fine at higher fps but there are some weird anomalies at low fps. Don’t know what it could be I will have a look at it but I don’t really worry about it.

At the start of the video I do some explaining for those who are not following my blog but the rest is just showing the game.

I would appreciate some comments about the video

Well not real madness, but the name of the project is “School Madness".

The project

I haven’t really talked about the school project I’m working on. To complete my school we have to take certain tests at the end of the year. But we also have to create a “product” that has to do with our education. Since I’m learning for a computer technician (translated) and we are doing different programming things in school I decided to create a game. It’s something I’m best at and it suits me. I probably have one of the most ambitious projects in our class. The standard also isn’t very high and so creating a simple game out of pure C++ using many different libraries (SDL, OpenGL, Freetype, FTGL, irrKlang) is way (waaaaaaaay) above it. So I’m not concerned by the fact that the game is really simple platformer. But I’m still trying to do my best.

The projects is really organized with much emphasis on OOP (Object Oriented Programming) and using the languages more complex features everywhere. I’m also writing short comments everywhere on my mentors request and so that if I will need to discuss the code I will immediately know what is where.

(A screen of the current project running)

Edit the level editor

Currently most of the work is going into the level editor. I’m making it user friendly and easy to use. I’m planning on making it the bigger thing in the game promoting creating your own levels. And I think it will be more fun than the simple platforming game. It’s clearly the best level editor I made so far with easy to create levels, test them, and saving/loading works from in-game.

Here you can see the editor menu opened up. By clicking Save/Load Level a “menu” pops up where you input the name of the level. It works really well and it’s the first time I done text input in a game.The red boxes around the objects are collision boxes. It adds a fancy/technical look to the editor.

I still have to add a camera to the editor and some more objects like the player spawn and exit. I will make the rooms a fixed size so that level creators can’t go crazy with it. After that is done I will focus on the actual platforming part of the game. I still think I have to add some kind of power to the player so that is adds some challenge to the game. I think that a double jump will do which the player will then use to do some of the more tricky moves. That way the game won’t be too boring because I’m not planning on adding enemies or moving (deadly) objects.

And that is all about the project for this post.

I have been sick in the last few days and wasn’t really able to do much. I have been learning some 3D modeling with Blender and it’s really interesting. Maybe in the future you will see some low poly models on this blog. But don’t expect any 3D games  

I also thought about starting to make video logs. Nothing complicated just a 1-5 minute video where I show you what I’m currently working on. For example on this post: I would show the code a little and how it’s structured, then I would run the game and show some of the features of the level editor and maybe run the player animation. Really simple. I think it would make a really nice addition and it wouldn’t take me much time to make them since I would make them totally spontaneously with no real goal. Fellow YouTube subscribers might appreciate new videos. Please give me some opinions about this idea in the comments. 

If you don’t know what I’m talking about here is a video log from Chevy Ray Johnston (An awesome indie game programmer/designer). If you can’t see the video click on the empty space and it should pop out.

Thanks for reading.

Everyone has a workspace, and it’s time that I show mine.

A room to work in

A picture is worth a thousand words, so I’ll just stick with that.

Not really high quality (I took the picture with my phone) but it should do. As you can see I use a “dual” monitor screen setup. I’m using my laptop (HP ProBook 4530s) all the time and have an external 21’ LG monitor hooked up to it. I use the big monitor for developing/programming and the small one for things like browsing, music and messaging. The laptop is not really a beast but it’s really good for any kind of development and it still runs most of the games. It’s really practical that I’m all the time one the laptop so that I can simply unplug it and go to school with it and continue there. My other computer (the gaming beast) is currently using my younger brother. I sometimes miss the power but as I said my laptop is good enough for me. I use a classic English layout HP keyboard and the Logitech G700 mouse. I usually listen music on my over 6 years old speakers.

My software setup is Windows 7 64x OS. I’m not using Linux, because it has really bad support for the ATI graphics card and Windows gives more battery power. I miss many Linux tools (I use a Virtual Machine when I really need them) but I really got confortable with Windows. Mainly because of his wide support for different developing environments and better software support. I can use Visual Studio for my IDE again and FlashDevelop for AS3 development. Windows also has Graphics Gale, the best pixel art graphics program. Other software I mostly use: Qt Creator (For C++ GUI development), Eclipse (Java Android development), Aptana Studio 3 (HTML, JS, CSS, PHP development), Inkscape (Vector art), GIMP (Raster graphics / free Photoshop clone), Windows Live Writer (Blog posting), Winamp (Music listening), Pidgin, Skype, Steam (You can find me as "#include<luka>" add me for a round of TF2), etc. There are more but I think this is enough.

As you can see I have a big whiteboard in the middle of the room. It has some “secret” things written on it but you won’t be able to read of it because of the high quality image. I just got the board yesterday so I still don’t have colored pens and it’s not as full and colorful as it will be.

In the bottom you can see my high tech TV with my Wii hooked up to it. My brother can’t understand how I can enjoy playing games on that TV size but I love it that way.

And that is mainly it. Nothing special really just my room where I made all the things you can find on my blog. Other interesting things on the picture: a Pokemon cup, fancy lamp, full trash bin and a copy of Zelda: Skyward Sword.

And that fellow readers was my room.

Whoa! A new post the same week as the last one. Well yea, I said that I will post more regularly. This post is about an old game of mine.

A better game

If you have been following my blog, you may have noticed that last February I posted about giving the source code of ‘Me and my shadow’ to a small team of developers. As it turns out the team is really passionate about the project and has brought the game to a completely new state. They revamped almost everything and added many great things. The game also has many new levels and a much better level editor. A completely new game but with the heart of the old one. I’m really happy and a little flattered that they took my game and made so much more out of it.

So what are you waiting for. If you liked the original or if you like platforming/puzzle games then you should really try it out. You can get the game from Sourceforge or from their site. There are also very open to anyone who would like to contribute to the project. Just check out the forums and ask where they need help. You can make new graphics, levels, sounds, music and if you are a programmer you can help them make the game even better.

I wish the guys good luck with the project and I hope that next year, I will be able to make a new post about an even better ‘Me and my shadow’

And another year has passed. The year I turned 18 and the year many things happened. You could also call it a year of my empty blog, because there wasn’t really anything on it. Well let’s change this.

A year in review

First let’s look back at year 2011. One could say that I didn’t do much in terms of game development, and that is probably true. I started the year with an “A game a month” project, but only completed 1 game. Then for the rest of the year… nothing. So it wasn’t really a good year for my game development.

On the other side, I accomplished many other things. I started working on my personal framework and can happily say, that I brought it to a state where I can use it for all my game development. It covers things like events, rendering, fonts, sound and game logic, and that is what I need. I will probably work more on the framework in the future, but for now I’ll leave it until I make a nice game out of it.

I also started making C++ game programming video tutorials. And they kind of “exploded” on the YouTube. I’m not saying that I got millions of views and thousand subscribers, but with 450 subscribers and over 100.000 views that were brought in just by these videos, I can say that I’m really happy with the result. And I hope I helped others find a way to create the game they want to make.

I also got 3rd place in the “national programming tournament” last year and that is something I’m proud of. I’m still using the mouse I got as an award.

I was in Ireland this year, working for a networking company, where I worked as a Python programmer. I learned much about Python and databases there and also got much experience from working abroad and for a real company. It’s something I won’t forget.

There ware also a ton of other small projects, which brought me much more knowledge in my expertise. Because of school, I had to take on many databases like PostgreSQL and MySQL. I also had to dig into Qt for C++, which is an amazing framework for GUI programs and almost everything not game based. It has so many different things you can use it’s simply amazing. And it’s cross-platform. I really recommend it to everyone who will try something else than games in C++. I also did some work in C#, learning the language and actually creating some things. I also got more into Android programming (with Java) and I plan to continue with it this year. Altogether I did a lot of different things and also finished many projects, which were never mentioned here because they were for other people or for school.

If I can sum up last year: I learned and created a lot of different things last year, which brought me a lot of experience and knowledge. But for my personal game development, well… you could say that was the worst year for it. But that’s OK.

New Year

This year there are big plans. I kind of got “mature” with computer programming and this, so I’m a lot more organized and hard working. I’m working more and more and not just slacking of playing games. I’m really trying to complete the projects I set myself.

Currently there are 3 bigger projects in works.

I am working really hard on making a new “C++ Game Programming” course/tutorial, but this time it’s for a paid site. The owners of the site saw my videos and asked me if I want to make something like that for their site. And I agreed. There are many videos already done and many more to be made. It’s going well, but making quality videos takes more time that usually. I really hope that people will like it so that I will make some money out of it. I would really want to make some money out of my works and I hope that this will be some kind of  a start point for me. I won’t tell many details about it, but when it’s done, I’ll make a post about it and make sure there will be coupons for those of you interested.

Because of that project the YouTube videos are on halt. I just can’t make both of them at the same time so they will have to wait. I don’t know if and when I will return to making more YouTube tutorials, but I can say that it won’t be soon. Sorry folks, but there are other priorities.

This year I also have my “finals” in school and I have to create a final project for that. I decided that I’m going to make a game. A simple Mario rip-off game, but I don’t mind, because it’s not a big project and won’t go public. It’s just something for school that I have to finish till March.

The last project. Well it’s a game. A quite big project for me and will probably be my first polished complete game (kinda) since JAHP. It’s also bigger that JAHP and more complex. I won’t tell anything about it, but I will post a screenshot when it’s so far. Currently I’m not working on it that much, because I’m making videos and I really have to create the game for school. But once that clears up, I’ll put all my effort back in the game.

So that’s all I had to say for now. Big things happened and are going to happen and I will make sure I’ll write much more on this blog so that you can read and see what’s currently happening. Have a nice day.

As I said, I'm going to Ireland tomorrow. So no new videos till I come back. I'm going to take pictures off the trip and everything so be tuned and check the blog for updates. I think that will make this blog a little more interesting.

Expect a post on Tuesday :)

Hello there. I would like to present you the newest 2 episodes. In them we create bricks, render them and do collision checking so we actually have something to break. Check them out:

Good morning on this nice spring day. I hope you had a nice April fools day :)

Now let's get some info out about what I've been doing in February and March. The first thing you have noticed is that I haven't released any game. I said that I won't release one in February but it seams that March was also kinda busy. But I was working on many things that just weren't games. First of all, in February I programmed a minesweeper solver for a national programming competition. I won the 3rd place and I am happy about it because before me were only college pupils. It was a great success which brought me a nice and fancy new mouse.

Here are the next 2 episodes. I am slowly getting better at this.



Hope you like them :)
