Python How to resize a rectangle in pygame?

[User8574]

How do I resize the rectangle and the border to look decent; so creating a margin basically?

Is it in the rect.draw code or the rectangle variable?

        restart_button = font.render('Restart', False, "black").convert()
        restart_rect = restart_button.get_rect(midbottom = (400,220))
        
        pygame.draw.rect(screen, 'white', restart_rect, 0)
        pygame.draw.rect(screen, 'black', restart_rect, 2)
        screen.blit(restart_button, restart_rect)

If you're trying to center the text, you can get the rect.center.

#! /usr/bin/env python3
import pygame as pg

# Initiate pygame and pygame fonts
pg.init()
pg.font.init()

# Screen width and height
width = 500
height = 400
screen = pg.display.set_mode((width, height))

# Create and set font and text
font = pg.font.SysFont(pg.font.get_fonts()[1], 20)
text = font.render('Some Text Here', True, (0,0,255))

# Create the rectangle
box = pg.Rect(10, 10, 220, 80)

running = True
while running:
    for event in pg.event.get():
        if event.type == pg.QUIT:
            running = False

    # Set background color
    screen.fill('white')

    # Draw the rectangle
    pg.draw.rect(screen, (255, 0, 0), box, width=1)

    # Get the text rect and center on the box rect
    text_rect = text.get_rect()
    text_rect.center = box.center

    # Blit to screen
    screen.blit(text, text_rect)

    pg.display.update()

On a side note, this will let you see available fonts in pygame

import pygame

fonts = pygame.font. get_fonts()

for i, font in enumerate(fonts):
    print(i, font)

There are probably better ways to make a button using a function but, here is one way

# Imports
import pygame

# Initiate pygame and pygame fonts
pygame.init()
pygame.font.init()

# Define screen size and background color
screen_size = (800, 600)
screen_bg = 'white'

# Set display and window caption
screen = pygame.display.set_mode(screen_size)
pygame.display.set_caption('A Pygame Window')

# Define framerate and clock
frames = 60
clock = pygame.time.Clock()

# Define the button function
def button(*args, text='Default Text', **kwargs):
    # Create and draw the box
    box = pygame.Rect(args[0], args[1], args[2], args[3])
    pygame.draw.rect(kwargs['surface'], kwargs['bgcolor'], box, kwargs['border_width'])

    # Setup the font
    font = pygame.font.SysFont(kwargs['font'], kwargs['fontsize'])
    text = font.render(text, True, kwargs['fontcolor'])

    # Get the text rect and set to box center
    text_rect  = text.get_rect()
    text_rect.center = box.center

    # Blit to the surface
    kwargs['surface'].blit(text, text_rect)

# Set running to True and start the loop
running = True
while running:

    # Set screen background color
    screen.fill(screen_bg)

    # Check for pygame events
    for event in pygame.event.get():

        # If pygame event is quit, set running to false and break out of loop
        if event.type == pygame.QUIT:
            running = False

    button(10,10,220,80, surface=screen, bgcolor='blue', border_width=0, font='comicsansms',\
           fontcolor='orange', fontsize=15)

    button(10,100,220,80, surface=screen, bgcolor='seagreen', border_width=0, font='tahoma',\
           fontcolor='lime', fontsize=20)

    button(10,190,220,80, surface=screen, bgcolor='burlywood', border_width=0, font='verdana',\
           fontcolor='tomato', fontsize=25)

    # Update pygame display and set framerate
    pygame.display.update()
    clock.tick(frames)

Last example of animated buttons with images

import pygame

pygame.init()
pygame.font.init()

# Setup pygame screen
screen_size = (800, 600)
screen = pygame.display.set_mode(screen_size)
pygame.display.set_caption('Pygame Button')

# Setup some colors
screen_bg = 'ivory2'

# Set framerate
fps = 60
framerate = pygame.time.Clock()

# Load and define button images. Three states normal, hover, and pressed
normal = pygame.image.load('normal.png')
hover = pygame.image.load('hover.png')
pressed = pygame.image.load('pressed.png')

# change cursor on hover
hand = pygame.SYSTEM_CURSOR_HAND

# Create Button class
class Button:
    def __init__(self, surface, image, pos, text, callback):
        '''
            Create a animated button from images
            self.callback is for a funtion for the button to do - set to None
        '''
        self.surface = surface
        self.image = image
        self.rect = self.image.get_rect(topleft=pos)
        self.text = text
        self.color = 'cyan'
        self.callback = callback


    # Define a function for writing text
    def write(self):
        font = pygame.font.SysFont('comicsansms', 18)
        text = font.render(self.text, True, self.color)
        text_rect = text.get_rect()
        text_rect.center = self.rect.center
        self.surface.blit(text, text_rect)


    # Define function for normal button state
    def normal(self):
        self.image = normal
        pygame.mouse.set_cursor()


    # Define function for mouse hover state
    def hover(self):
        self.image = hover
        pygame.mouse.set_cursor(hand)


    # Define function for pressed state
    def pressed(self):
        self.image = pressed


# Set a variabe to True and enter loop
running = True
while running:

    # Fill screen with background color
    screen.fill(screen_bg)

    # Start event loop
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # Create a button from the Button class with args for state, position, and callback
    button = Button(screen, normal, (100, 100), 'Button', None)

    # Get mouse button from pygame
    left, middle, right = pygame.mouse.get_pressed()

    # If cursor is over button change state to hover else state is normal
    if button.rect.collidepoint(pygame.mouse.get_pos()):
        button.color = 'white'
        button.hover()

        # If left mouse button pressed change state to pressed else hover
        if left and button.rect.collidepoint(pygame.mouse.get_pos()):
            button.color = 'black'
            button.pressed()
        # else:
        #     button.hover()
    else:
        button.normal()

    # Blit button to screen
    screen.blit(button.image, button.rect)
    button.write()

    # Set framerate and update
    framerate.tick(fps)
    pygame.display.update()
