Add color breezing effect in pygame

Introduction

Pygame is a Python-based multimedia toolkit for creating games and other multimedia applications. In this lesson, we'll utilize the pygame module to create various shapes on the screen while considering their height, width, and position in the pygame window.

Pygame is a Python wrapper for SDL, for Simple DirectMedia Layer. SDL allows you to access your system's multimedia hardware, including sound, video, mouse, keyboard, and joystick, from any platform. To replace the now-defunct PySDL project, the pygame project was formed. You can construct games and rich multimedia Python programs on any platform that supports SDL and pygame because they are cross-platform!

Pygame

Pygame is a Python package designed primarily for creating and designing games. Pygame only supports 2D games created with various sprites. Pygame isn't ideal for game development because it's challenging to use and lacks an actual GUI like Unity, but it does provide logic for more sophisticated applications.

Installation: We must first install the pygame library before using it. In the terminal, execute the following command to install it.

pip install pygame

Color Breezing effect:

Pygame has color coding in the form of a tuple with three values representing the intensities of the three primary hues (red, blue, and green). The values of the unique hues can be modified to create a different color. Because the tuple's values can be changed at runtime, we can use them to add color effects to make our game/application more distinctive and beautiful.

A breezing effect is one of the color effects; it is an effect in which the Color shifts from one shade to another gently without a sudden or abrupt change. The RGB keyboard and mouse display these effects.

Example:

import pygame
import random
import sys

# initialized the constructor
pygame.init()

# set up of variable screen
scrn = pygame.display.set_mode((720,720))

# three arguments of the color tuple
c_1 = random.randint(0,255)
c_2 = random.randint(0,255)
c_3 = random.randint(0,255)

# setting up variable clock
clck = pygame.time.Clock()

while True:
for e_v in pygame.event.get():
if e_v.type == pygame.QUIT:
pygame.quit()

# increasing the shade of
# the current selected color
if 0 < c_1 < 255:
c_1 += 1

# if value of c_1 exceeds
# 255 it returns to 0
elif c_1 >= 255:
c_1 -= 255

# if value of c_1 precedes 0
# it gets incremented by 3
elif c_1 <= 0:
c_1 += 3

# set the game fps to 60
clock.tick(60)

# sets bg color to tuple
# (c_1,c_2,c_3)
screen.fill((c_1,c_2,c_3))

# updates the frames of
# the game
pygame.display.update()

Frequently Asked Questions

In Pygame, how do you alter the color of a surface?

The fill function loops over the pixels on the Surface and changes their Color while keeping their alpha value. This is probably not something you should perform every frame with many characters. (To change the Color, press f, g, or h.) I've included a transparent image in my response to make the impact more visible.

How do I change the hue in Pygame?

PixelArray can be used to loop over each pixel in a picture, Surface. Unmap RGB to extract a Color object from each pixel and Color. hsla to do the hue shift. This could be done in real-time if the Surface is small.

How do you blur the background in pygame?

Scaling the Surface with pygame is a workaround. Transform. Iterating over each pixel, smooth scale, then back to original size (ugly). Set the color of the pixel after calculating the average value for red, green, and blue (slow as hell if not using something like NumPy )

What is a pygame surface?

A pygame Any image can be represented by a surface. The Surface has a set pixel format and resolution. Color palettes are used to map 8-bit pixels to 24-bit colors on surfaces. Invoke pygame. To build a new image object, use the Surface () pygame object for expressing images.

What is Blitting in python?

blit(background,(x,y)), where (x,y) is the window coordinates for the top left corner of the surface. This process explains you to draw the background surface onto the screen and set it at the desired location (x,y).
