Snowing Effect in Monkey X

Since Christmas is coming soon, I decided to share my snowing effect code I wrote last year. The original code was written in BlitzMax. This year I have already made new Christmas intro in Monkey X. You may want to take look at the snowing effect of the Christmas video of the last year.

Examine the code and you’ll get the idea quickly. Implementation in other programming languages should be quit straight forward. Just use background picture of your own.

Feel free to use the code.

If the featured image doesn’t show up, below is a screenshot of the program:

I will soon publish my new Merry Christmas 2017 and Happy New Year 2018 video. And… It’s also written in Monkey X.

What if Smart Screen blocks my product?

What if Smart Screen prevents my product to run on your computer? You can check the file before running it with some antivirus scanner and as you see, that there’s nothing harmful, just run the program. See the video (I have Finnish system, but I have added needed translations):

My system is protected by F-Secure’s protection package. If you have F-Secure’s protection too, and Deep Guard says it has prevented harmful program to run (in Finnish: ”Deep Guard on estänyt haitallisen tiedoston”), you may still do the same scanning as shown in the video and as you see, that the program is actually clean, don’t be afraid of running it.

Though, if the Deep Guard prevents the program to run, one must manually allow the Deep Guard to run the program, by changing F-Secure’s AV settings in order to put the program to the list of allowed programs.

In case you ran into any problems, just contact me by e-mail and we’ll find a solution together.

In order to prevent the Smart Screen to block a program one should have a certificate and put the certificate into one’s program after one has validated it with Microsoft’s validator. But the certificate is expensive…

Also, many of you may have noticed that one somekind of generic interpretation of a “virus” or some harmful file is often just a rare file, rare piece of software nowadays… The definition of rare is sometimes just new.

Unique Random Integers part II

Last year I wrote about my clumsy implementation of unique random integers system, I’ve used in my Memorable Ladies games. In those the speed isn’t a critical factor. It’s sufficient that the idea works. 🙂

In this post the idea behind unique random integers is the same, but implemented in a faster way.

In the implementation I have used an array that consists of all desired integers and each is drawn in a way that the same integer doesn’t get drawn again. Let’s take a look at the code (I have used Monkey2 programming language in the example):

First an array is initialized with desired integers. Then an random integer from the array is fetched using random index inside the array.  After that the numbers after the drawn number are moved to “left”. For the end the amount of integers is decreased by 1 and the array is resized by the new amount of integers. That’s it.

This way one gets always different random integer from the set of desired integers.

Furthermore, if one would like to get, for example, number four (4) to be drawn three times, one could just include 4 three times in the array.

Depending on what one is doing, one could keep a copy of the original array for future usage.

Although I have used Monkey2 as example programming language, it should be easy to implement similar implementation to many other programming languages quite straight forwardly.

 

 

How To Fix Missing OpenAL32-dll Problem in Windows 10

Missing OpenAL32.dll problem seem to be common problem with many software.

First how the solution can’t be solved: At least in 64-bit Windows 10 grabbing just OpenAL32.dll and registering it to system with regsvr32 doesn’t work. There are some bad solutions to solve this problem. The best solution is simply grabbing the missing dll from http://www.openal.org/ and install it with the official installer it comes with.

In general, if one is missing some software component, it is best to find the official website of the missing software component and hope for the best.

This is how to fix the problem when setting up Monkey X installation, too.

 

Example of Own Font Class in Monkey X part 2

I decided to implement in an alternative way own font class to Monkey X to use with fonts converted with my Font 2 PNG, just to for passing time.

Check the previous post or the homepage of Font 2 PNG for format of the dat-file.

Screenshot of the program:

All you really have to understand is the simple format of the dat-file of a font to understand the source code below — and of course basic understanding of Monkey X.

Feel free to use the code above.

 

Example of Own Font Class in Monkey X

I seem to live in the past… Monkey X programming language has evolved into Monkey2, but I’m still sometimes using Monkey X.

I made an example class to use in Monkey X with bitmap fonts converted with my Font 2 PNG. The example uses old Mojo-module, but old examples on scaling bitmap font made with Font 2 PNG will give you an idea of an alternative way to implementing this.

Next, let’s take a look at a screenshot:

Next to the code:

Font 2 PNG prints the max height of the font after converting. The value is in practice just the height of the png-file.

As a reminder: Font 2 PNG produces two files, font.png and font.dat for one font. The font.dat-file holds the information for each character with two 4 byte integers, first tells the position in pixels in font, the second the width of the chatacter in pixels.

I hope this example gives you some ideas on how to use different fonts converted with Font 2 PNG.

Feel free to use the code above.

PS. I also made new version of part 1 of my Old School series demonstration in Monkey X. Video below:

From the source code in the video you’ll get an idea, how this font class could be used with Mojo2-module.

That’s it from my “hobby corner” tonight!

Old School IX

This morning I made new Old School demonstration in Monkey X. This is now 9th in the series.

Not much is changed in the code from the previous Old School demonstration. What actually required some work, was the font. As in all my Old School demonstrations, I used my Font 2 PNG program. With Mojo2-module one can use for one picture the following: “pic.png”, “pic_n.png” and “pic_s.png”. The programmer doesn’t need to worry about “_n” and “_s” versions of an image, Mojo2 takes care of them. I’ve written all I know from those extra pictures in the first old school post. I may make a better version of it in code-wise and perhaps add some extra too…

Anyway in this 9th version there are 3 versions of each character that are individual png-files.

See the magic: 🙂

I may share the Monkey X source code for these later Old School demonstrations later.

Rolling and Rotating scrolltext (Old School VIII)

I made today a little Monkey X Pro demonstration: Rolling and rotating scrolltext (Old School VIII). Now it works perfectly. Like in Old School VII, the letters fade in and out at the bottom of the circle of letters. I have used my Font 2 PNG program to grab individual characters of a ttf-font to png-images for the program. Perhaps I will later share the source code of the demonstration…

Enjoy the nostalgia! 🙂

The idea behind the code of the rolling and rotating scrolltext:

  • At every update frame 30 characters (png-images) from the scrolltext are drawn in a form of a circle, each character with 12 degrees step (12 *30 = 360), let angle related to this angle be angle1
  • When drawing the character images, the angle that increases in 12 steps is added to each character in addition to this angle is added other angle variable, let this be angle2, that is decreased (the direction of rolling and rotating) by 1 degrees at every update frame
  • Because of my (probably clumsy but working 🙂 )implementation:
  • in DrawImage method rotation angle is angle1 + angle2 + constant that adjusts the letters to the right place on the circle

As to he fade out and fade in for the letter images, you may adjust the letters with alpha values as you best you see it is sensible, probably somewhere at the bottom of the circle.

That’s it! Do try to make make your own version with programming language of your choice. I recommend my Font 2 PNG program for the font.

Good luck!

The first time I saw this kind of effect created was some time in the late 80s on Amiga in following demo:

Ah! Those good old Amiga demos. Kind of magic at their time.

Old School VI 2 and VII Videos

I recently made version 2 from my poor Old School VI video. Today I got finished Old School VII video. Both demonstrations are programmed in Monkey X Pro. VII has that nice demo scene style synth music like Old School V. 🙂

In the Old School VII the the new letters fade in to the screen as the scroll text goes on and when the letters have gone the whole circle, they fade out…

Let the nostalgia flow through you!

First Old School VII:

…then Old School VI 2

I hope you enjoy the videos!

Scaling ttf-font in Monkey2

In Monkey2 programming language it is possible to load ttf (and otf & fon) font directly and use the DrawText method of canvas to draw the text. But how to scale the font? In this example I made today it is done in a clumsy way, but may give you some ideas…
