<p>Tiny web server called Local Host Access (<strong>LHA</strong>) is ready to replace
Local File System Access (<strong>LFSA</strong>) on JVM and macOS: I've generated this
very article with LHA on macOS. Thus, Kotlin prooved to be a good choice for
cross-platform development with a minor limitation.</p>
<p>The minor limitation is the fact that 99% of Kotlin is used on JVM. The
remaining 1% is so-called Kotlin Native for iOS, Linux, macOS, and Windows.
Thus, when one needs something as simple as to find out if a symlink. . .</p>

<p>Helper script is used to bypass web page restriction to access

Eugene - left.</p>

<p>In August I implemented scene switching, which allowed me to do the following:</p>
<ul>
<li>pressing "Start the game" button in the splash screen takes the player to a level with three floors</li>
<li>selecting a door takes the player to another floor</li>
<li>selecting a TV set focuses the player on the TV set with a remote control</li>
<li>switching TV channels results in different images being shown</li>
</ul>
<p>Thus, scenes are good both for focusing on items and moving the player around.. . .</p>

<p>When July started my initial plan was to make the instrument support Python to
JavaScript code translation. However, this did not happen because tasks with
higher priority emerged.</p>
<p>Which task is more important than develpment of the instrument?
Development of a game, of course! Now, let's go back to the beginning of
July 2024…</p>

<p>In June I implemented GUI for "Memory" game in Python with the help of
<a href="https://arcade.academy">Python Arcade</a>.</p>
<p>While searching for the most convenient tool to create resources (assets), I found
notebooks lined with graph paper to work the best:</p>

<p>To see the portable code architecture in real life, I participated in the 3-day long
gamejam of <a href="https://dtf.ru/games/2783053-nachni-igru-ocenka-videorolikov">"Start the game"</a>. "Memory" game was used with a customized look to satisfy jam requirements.</p>

<p>In May I implemented text UI for "Memory" game in Python. And converted it to C++
by the instrument under development.</p>
<p>Game logic cycle implementation lead to the creation of a controller that manages
context. Creating the controller in Python was straightforward. C++ version took
some time, because the controller needs <a href="https://en.cppreference.com/w/cpp/utility/any">std::any</a>, which is part of C++17.
The instrument under development is limited to C++11 in order to support OpenWrt.</p>
<p>Here's how much code I wrote (in lines):. . .</p>

<h1 id="memorygamelogic">"Memory" game logic</h1>
<p>In April I implemented "Memory" game logic in Python as limited language model and successfully converted the code to C++ by the instrument under development.</p>
<p>Limited language model assumes the following architecture of two parts:</p>
<ol>
<li>state context</li>
<li>pure functions without side effects working only with the context</li>
</ol>
<p>Game logic state context in Python currently looks like this (<a href="https://git.opengamestudio.org/kornerr/research-portable-memory/src/commit/6fcd542daa6242c8c23dddb88d04cda74a730328/v3/memory_Context.h">C++</a>):</p>

<p>To verify code portability, I selected the following platforms and languages:</p>

<li>JavaScript: Chrome, Firefox, Safari</li>
<li>Kotlin: Android</li>
<li>Python: Linux, macOS, Windows</li>
<li>Swift: iOS, macOS</li>
</ul>
<p>I created a simple "Hello World" example for each language to understand the basic requirements of each platform.</p>
<p>By the way, OpenWrt turned out the most complex platform to create "Hello World" for, because my TP-Link TL-MR3020 r1 router is considered obsolete since 2018. I had to use the old 17.01.7 firmware, which took about three weeks.. . .</p>
