Dynamic smoke effect based on python

introduction

Dynamic smoke effects are often used in games and animations, adding realistic visual effects to the scene. In this blog, we will use Python and Pygame libraries to create a realistic smoke animation effect. By simulating the movement and transparency changes of smoke particles, we can achieve a lifelike smoke effect.

Preparation

Prerequisites

Before you start, you need to make sure your system has Pygame library installed. If you haven't installed it yet, you can install it using the following command:

pip install pygame

Pygame is a cross-platform Python module for writing video games. It includes computer graphics and sound libraries, making game development easier.

Code implementation and parsing

Import the necessary libraries

We first need to import the Pygame library and other necessary modules:

import pygame
import random

Initialize Pygame

We need to initialize Pygame and set the basic parameters of the screen:

()
screen = .set_mode((800, 600))
.set_caption("Dynamic Smoke Effect")
clock = ()

Define smoke particles

Let's create aSmokeParticleClasses to define the properties and behavior of smoke particles:

class SmokeParticle:
    def __init__(self, x, y):
         = x
         = y
         = (5, 15)
         = (200, 200, 200)
         = (50, 150)
         = 0
         = (1, 3)
         = (-1, 1)

    def update(self):
         += 
         -= 
         += 1
         -= 0.1
        if  < 0:
             = 0

    def is_alive(self):
        return  <

Create smoke particle effects

We define a function to generate and manage smoke particles:

particles = []

def create_smoke(x, y):
    for _ in range(5):
        (SmokeParticle(x, y))

def update_and_draw_particles(screen):
    for particle in particles[:]:
        if particle.is_alive():
            ()
            (screen,  + (int(255 * (1 -  / )),), 
                               (int(), int()), int())
        else:
            (particle)

Main loop

We update and draw smoke particles in the main loop:

running = True
while running:
    for event in ():
        if  == :
            running = False

    ((0, 0, 0))
    
    create_smoke(400, 300)
    update_and_draw_particles(screen)

    ()
    (30)
