Calculus v3.2.0 to Android

I’ve been on fever for several days now, when I’m writing this. Nevertheless, now Calculus is at version 3.2.0 beta. Finally saving to Pictures folder work properly — also in later (>=6) Android versions.

One new feature is also possibility to make y limits equal to x limits With this button one can get results like this:

The video below is recorder directly from my phones screen:

Let’s see if I manage to implement some new features to Calculus in near future.

UFOs back in Defense II

It seems, that someone had deleted the UFO graphics file from my online game Defense II. Now the UFOs are back. Instead of UFOs, there were only filled circles flying in the playing area.

My firewall plugin has recently blocked some IPs. I guess some people “have too much time”, that is: they have the time to do bad things to others.

Perhaps you should go to see this game and defend the neighborhood from UFOs. 🙂

Three tunes that were left out from Memorable Melodies

When I made the short old school synth tunes for Memorable Melodies, I made them all in one night.

There are three tunes I left out from the game. I guess these were just experimental tunes to set me in the “composing” mood. I made today a YouTube video from those three tunes:

Try the free game to get a impression, how the tunes turned out to be, that were included in the game. Remember, there is a cheat in the game: By tapping top right corner of the screen during game play, all the mistakes are cleared.

The latest version of Memorable Melodies is 1.4.

As you can see from the ProTrekkr window in the video, I’ve been making an Air Wolf cover with ProTrekkr. If I ever get it finished, I will publish a blog post here, where you can here the result.

On Easy Math Challenge development

I’d like to tell, why and what kind of bugs there were in my Android game Easy Math Challenge in its early versions.

The smallest bug was that there was “difficulty level 0”. If the user tapped somewhere else than the difficulty level buttons, the game gave “puzzles” like “3 = 3”. Well, those “puzzles” were always correct. This was fixed later.

The more annoying bug was, that in early versions the puzzles sometimes might be impossible.

The reason for that was, that I’ve used numbers also for the operations of puzzles. If for example + (plus) was 45, while calculating the result, the result got wrong so that 45 was part of the calculation numbers, not an operation. This was fixed later.

Video of the version 1.7.2 (no known bugs):

I wrote the program from scratch without any planning and often the usual mistake of mine: Work was done too at too late of hours.

If you still find some bugs, please let me know.

 

 

How I made it on Music Game Jam 2018

My contribution to Music Game Jam 2018 was very quickly made. There was 2 weeks time and later some more time was given, but I made my game practically in two days. My ranking on the jam was 78th / 99. The Plus-version was made even in shorter time.

Below is a video from Build a Tune Plus, which is my thank you for your comments and downloads:

I probably should start (or learn) to make again music.. The short ending music for the Plus-version is made recently. The downloads are available below:

I signed today the exe files with the OV code signing certificate.

On Signing a Windows App

First I would like to tell you, that I have purchased an OV code signing certificate for one year. I found out from a blog, that K Software has at the moment the cheapest OV code signing certificate, $84 for one year.

As MicroSoft says in their documents, you must have a certificate, if you want to distribute or sell Windows apps.

There are three main categories of certificates on Windows platform: Open Source code signing, OV code signing and EV code signing.

The first is the cheapest — in the best case free — the last is the most expensive.

Open source code signing suits you if you do open source projects. You can check the definition of open source development here.

In the other cases the other two mentioned certificates are for you.

The OV certificate doesn’t prevent at first the smart screen to appear. In time, when you get enough downloads the smart screen won’t appear anymore. The EV certificate that is the most expensive, gives you immediate trust and no more smart screen to your apps.

The main benefit of OV certificate is, that none of the AV software programs considers your precious application a harmful file.

Once you have the certificate, signing the exe is as easy as follows:

The signtool.exe can be found at c:\program files (x86)\Windows Kits\… The appropriate path should be added to your system’s %path% environment variable. If you don’t have …\Windows Kits\ search the internet for Windows SDK version 8.1 or 10.

I have today signed most of my Windows apps. Smart screen will at first still warn you, but the file is no more considered a harmful file.

My Thank You for comments and downloads on Music Game Jam 2018

I want thank for all the comments and downloads on Music Game Jam 2018 with Build a Tune Plus. The game consists not only one level, but three levels and an ending. 🙂 All music made by me.

The game can be downloaded from the Build a Tune page on itch.io.

On the same page there is the original Build a Tune.

Thank you!

Order the Chaos as Online Game

I published yesterday Order the Chaos as online game. The online version is some kind of lite version of the original BlitzMax game.

Link to game.

The game has a bit simpler ending because of the limitations of HTML5.

The resolution of the game is 648 x 720 pixels.

Order the Chaos II — more polished version and with large (the playing area is scrolled) Mandelbrot mountains is of course available on itch.io.

The online version of Order the Chaos works with mobile devices, too.

My Color 2 Transparent Online Tool

I think many of you may not have noticed (I can be wrong, though) that I have an handy online tool to make a certain color in a picture to transparent. The tool works at least with Chrome and Fire Fox. It’s quite slow but works well on small pictures.

The URL is https://blue-bit-entertainment.com/color2transparent/

Below is a video of me using the tool:

My system is in Finnish, but I have added some translations to the video.

Do use it, if you have use of this kind of tool.
