I made a program to comment on selected youtube videos. I made this using java/javafx source code available. You can download the app here:

Im nearly finished making my own youtube commenter. I just need to add icons for the buttons and maybe do some testing… If you like it then subscribe:


A keystroke logger program which resides on tray. The app is displayed when the tray icon is double clicked. The app features display of keystroke logs including time and date of each key pressed. it also has the simple analyzation tool, and the ability to email the file to others.

The theme is changeable and you can make one. It is under JavaFX’s CSS so it will be mostly familiar to all. All the themes must be saved under the “css” folder.

If you are bored with gamedev or programming, game jams is a thing you need to try. In october 2016 I found my self bored with c++ madness. Suddenly, I found a blog post about great game jam, that will help you to re-think your skills.

Ludum dare is one of the worlds largest and longest running Game Jam events. Every 4 months, people make a game from scratch in a weekend.

Sounds neat right?

I though, I will have a try. My first LD (37), I wrote an RPG-kind of game:


It was my first experience of java game development, I was completely to game jams. Any way, I did a great job, and I was proud of my self, because I did compo first try. Things I noticed:

  • Ascii art is great, but doen’t fit game jams
  • My java framework was buggy
  • I did not have any clue, how to make music

But, what I enjoyed a lot, that I got new inspiration from the jam and the positive feedback from people. It was so lovely, to hear great words about your game!


Till the LD, there is always a few streamers, that stream their development. When I saw that on LD 37, I thought, that it would be nice to try this. I wrote a small plugin, witch can be found here. Not the best code ever, and the idea is taken from Drunk Devs on twitch.

The plugin it self is a twitch chat bot, that displays all of the users, that had typed something in the chat, on the screen. And every 7-10 minutes happens a random event, that users can vote for.


The truth

My stream got 0 viewers :) Strange, isn’t it? Also, my PC was not powerful enough. When the chat bot was active, my PC was lagging so much…

Another way to do this

Next LD (it will be in summer 2017), I will record a time lapse, and post it on youtube. Hope, that it will go better.

Wait, but what about LD 38?

Ah.. it was a complete fail.. First of all, in a few hours before jam, i found pico-8. I thought: “Well, I write a game-emulator, this can fit almost every theme..”. I created a prototype console, and got to bed.

When the theme was announced (it was Small World), I though, that this theme is great for writing an emulator.

The first day went alright. But on the second day, I just did not know, what to do.. I mean, I run out of ideas. My game was not playable enough. There was not enough time to start another game.

I just failed.

By the way, game is here:



Never start a brain storming before LD. Otherwise, you will fail.. Trust me. Next time, I will use lua + love2d for my game. And no ascii art!!

I made the getComponent() similar to unity in which you use Generic in method to get the component that you want.




I’m in for LD38 – Round Two

I’m planning to try again for LD 38, likely for the Jam instead of Compo.

My first Ludum Dare was LD 37, where I tried the jam by myself and music from my brother. However, things didn’t end quite so well, as I wasn’t able to get function version to distribute by the end of the 72 hours. After the event, I did at least resolve the major bugs into the version you can find here on my There is not much substance to the game, but it’s something I made in four-days time so that’s one step at least.

Pre-Event Thoughts

One thing I learned from the last event was to improve my time management. I ran short on time to get a functional game. I spent too much time with small details that ended up not being used in my rush to finish the game in some form where people could at minimum click the button. Ludum Dare 37 was my second project using libGDX and my first project using Ashley for entities and Box2D for physics. I learned a lot, especially using some other open-source projects to get some general ideas and guidelines.

With LD 38 coming up, I’m hoping to get a more complete, more enjoyable game than my LD 37. I will have less time than before due to work, but I’ll still have a decent amount of time. I want to create something minimally substantial, preferably an idea that I would want to go back to later and continue.


I’ll use Java and the libGDX game framework.
I will probably use Ashley as an entity-component management system.
I will probably use Box2D for any physics/collisions.
For sounds, I’ll use sfxr/bfxr.
Music I will either create using musagi.
Art will be created using

Just check it out

As reference to my earlier post about the shapedrawing program (java2d):

Source code:

Someone in youtube commented that maybe I should try to export the images in svg format. So here it is. I found a way to save the image into SVG format. I used a lib called ImageTracer. Below is the sample. I love the mousepad though (the mousepad with the sexy girl).

It’s rushed but I made it for school activities. It is even saveable (PNG image type). The source code is included in the youtube link description. Source code:


Last valentines I drew something using the program:


next time maybe I’ll make a pixel type software just for fun. With, image processing techniques maybe (using famous algorithms). Also subscribe to my channel.

1. The game is not finished cause I don’t have enough time(school…)
2. My first time Making music

– W,A,S,D
– Arrow Keys
you can choose

The core idea is that you have a music bar and if you run out of music you
die! It’s a 2D Platforming fun game you can play at home!
Because of school, I am not able to add items and such so the game isn’t
for this MiniLD! I may have a go and continue development soon on my
YouTube channel!

I’m a 14-year-old self-taught programmer!
I upload develops tutorials and much more to my new Youtube Channel calledHellowPixl!
Because in just 14 and self-taught please rate fair!

– Eclipse
– Audacity
– Photoshop cs2 (it’s fully free)

Hey fellow developers and players,
I just uploaded a time lapse from my game making process of my card game “Bloodshifter“. I built the whole game from scratch in Java, so if you are interested in seeing that then here it is:

You can try out the game for yourself here. Thanks a lot.

After some hours I’ve been able to complete a very first prototype with the basic gameplay working and end condition. You have to survive by being in a safe (black) place because every few seconds the background map will come to foreground, be sure to move to a good (black) position.

I think this time I will work less hours, now it’s 23:36 here and after playing a little bit I’ll go to bed. I prefer to wake up early and continue adding the HUD, sounds and other effects.
