Python Desktop Pet with PyQt5 – Implementation Guide

The desktop pet is built by randomly switching GIF animations; you can replace the GIFs yourself and the source code is provided at the end of the article.

The final effect is a pet that floats above all windows, moves, can be clicked, interacts, and can be dragged freely.

Project resources include dialog.txt for pet dialogues, tigerIcon.jpg for the tray icon, and GIF files placed in normal/ and click/ directories.

Required Python packages (install via pip ) are:

<code>import os</code><code>import sys</code><code>import random</code><code>from PyQt5.QtGui import *</code><code>from PyQt5.QtCore import *</code><code>from PyQt5.QtWidgets import *</code>

The program’s main flow consists of four key methods:

self.init() – initializes the window and starts the pet GIF.

self.initPall() – configures system tray behavior.

self.initPetImage() – loads static GIF resources, dialogues, and images.

self.petNormalAction() – enables random action switching and dialogue updates.

To package the script as an executable, run:

<code>pip install pyinstaller</code><code>pyinstaller -F -w main.py</code>

Pet image loading

<code>def initPetImage(self):</code><code>    self.talkLabel = QLabel(self)</code><code>    self.talkLabel.setStyleSheet("font:15pt '楷体';border-width: 1px;color:blue;")</code><code>    self.image = QLabel(self)</code><code>    self.movie = QMovie("normal/normal1.gif")</code><code>    self.movie.setScaledSize(QSize(200, 200))</code><code>    self.image.setMovie(self.movie)</code><code>    self.movie.start()</code><code>    self.resize(1024, 1024)</code><code>    self.randomPosition()</code><code>    self.show()</code><code>    self.pet1 = []</code><code>    for i in os.listdir("normal"):</code><code>        self.pet1.append("normal/" + i)</code><code>    self.dialog = []</code><code>    with open("dialog.txt", "r") as f:</code><code>        text = f.read()</code><code>    self.dialog = text.split("\n")</code>

Pet normal action (random GIF switching)

<code>def petNormalAction(self):</code><code>    self.timer = QTimer()</code><code>    self.timer.timeout.connect(self.randomAct)</code><code>    self.timer.start(3000)</code><code>    self.condition = 0</code><code>    self.talkTimer = QTimer()</code><code>    self.talkTimer.timeout.connect(self.talk)</code><code>    self.talkTimer.start(3000)</code><code>    self.talk_condition = 0</code><code>    self.talk()</code>

Random action switching

<code>def randomAct(self):</code><code>    if not self.condition:</code><code>        self.movie = QMovie(random.choice(self.pet1))</code><code>        self.movie.setScaledSize(QSize(200, 200))</code><code>        self.image.setMovie(self.movie)</code><code>        self.movie.start()</code><code>    else:</code><code>        self.movie = QMovie("./click/click.gif")</code><code>        self.movie.setScaledSize(QSize(200, 200))</code><code>        self.image.setMovie(self.movie)</code><code>        self.movie.start()</code><code>        self.condition = 0</code><code>        self.talk_condition = 0</code>

Dialogue display

<code>def talk(self):</code><code>    if not self.talk_condition:</code><code>        self.talkLabel.setText(random.choice(self.dialog))</code><code>        self.talkLabel.setStyleSheet("font: bold; font:25pt '楷体'; color:white; background-color: white")</code><code>        self.talkLabel.adjustSize()</code><code>    else:</code><code>        self.talkLabel.setText("别点我")</code><code>        self.talkLabel.setStyleSheet("font: bold; font:25pt '楷体'; color:white; background-color: white")</code><code>        self.talkLabel.adjustSize()</code><code>    self.talk_condition = 0</code>
