Back to the development of "PSKOV"

"PSKOV" today

Now, we have an old "PSKOV" version and we need an improved one.

First, we should recall what "PSKOV" consists of:

  1. The generator itself in the form of HTML page with JavaScript
  2. Helper Python script to save generated files to disk

Helper script is used to bypass web page restriction to access local file system.

The script itself is a tiny web server with the following commands:

Command Details
1 GET /path Get current working directory path

Sound support and the search for a new direction

Sound support

In September I implemented sound support. However, this was the last work for "Tail and Shadow" project, because the project's story writer - Eugene - left.

The search for a new direction

In September I also noticed the loss of interest in the project by the audience. I linked this to the fact that the project's functional and graphical results did not match that of the audience.. . .

Switching scenes

August

In August I implemented scene switching, which allowed me to do the following:

  • pressing "Start the game" button in the splash screen takes the player to a level with three floors
  • selecting a door takes the player to another floor
  • selecting a TV set focuses the player on the TV set with a remote control
  • switching TV channels results in different images being shown

Thus, scenes are good both for focusing on items and moving the player around.. . .

Game

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.

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…

Gamejam

"Start the game" 3-day gamejam finished in the beginning of July 2024. I participated in the jam to validate the instrument under development and. . .

"Memory" GUI

"Memory" GUI

In June I implemented GUI for "Memory" game in Python with the help of Python Arcade.

While searching for the most convenient tool to create resources (assets), I found notebooks lined with graph paper to work the best:

Texture of a notebook

To see the portable code architecture in real life, I participated in the 3-day long gamejam of "Start the game". "Memory" game was used with a customized look to satisfy jam requirements.

Here's how the customized version looks like (Windows64 build):. . .

"Memory" text UI

"Memory" text UI

In May I implemented text UI for "Memory" game in Python. And converted it to C++ by the instrument under development.

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 std::any, which is part of C++17. The instrument under development is limited to C++11 in order to support OpenWrt.

Here's how much code I wrote (in lines):. . .

"Memory" game logic

"Memory" game logic

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.

Limited language model assumes the following architecture of two parts:

  1. state context
  2. pure functions without side effects working only with the context

Game logic state context in Python currently looks like this (C++):

```python class memory_Context: def init(self): self.hiddenItems = []. . .

The first example of a portable code

Supported platforms

To verify code portability, I selected the following platforms and languages:

  • C++: Linux, macOS, OpenWrt, Windows
  • JavaScript: Chrome, Firefox, Safari
  • Kotlin: Android
  • Python: Linux, macOS, Windows
  • Swift: iOS, macOS

I created a simple "Hello World" example for each language to understand the basic requirements of each platform.

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.. . .

Шина-iOS

The first Bus pattern implementation for iOS

I spent January and February making Bus pattern implementation in Swift for iOS. The end result looks nice to me.

I have also done load testing. Turns out, the Bus is 92 times more expensive than a function call. Nonetheless, this doesn't mean the Bus is bad. On the contrary, the numbers highlight the Bus should be used in architectural glue code where it can save up to 30% of code

This example demonstrates several states rendered through a single instance:. . .
