• how to adapt the window to the screen size of the monitor with pygame.display.Info()

how to animate a text in pygame

python powered

import pygame
import time


class Color:
	green = (0, 255, 0)


class Font:
	''' definition of type of fonts '''
	pygame.font.init()
	little = pygame.font.SysFont("Arial", 48)
	big = pygame.font.SysFont("Arial", 192)


class Text:
	''' definition of text with rendering method '''
	def text_render(font, text, color):
		text = font.render(text, 1, color)
		return text

	def show_text(enter=None):
		

		def animate(text, pos):
			width1 = text.get_size()[0]
			for n in range(width1):
				screen.fill(0)
				screen.blit(text, (-width1 + n, pos))
				clock.tick(360)
				pygame.display.update()
		
		def pause():
			for n in range(100):
				screen.blit(Text.hello, (0, 0))
				screen.blit(Text.world, (0, 200))
				pygame.display.update()
		
		if enter == None:
			screen.blit(Text.hello, (0, 0))
			screen.blit(Text.world, (0, 200))

		elif enter == "from_left":
			# width1 = Text.hello.get_size()[0]
			width2 = Text.world.get_size()[0]
			animate(Text.hello, 0)
			animate(Text.world, 200)
			pause()



	hello = text_render(Font.big, "Hello", Color.green)
	world = text_render(Font.little, "World", Color.green)


def monitor_size():
	''' return width and height of the monitor screen '''
	info = pygame.display.Info()
	return info.current_w, info.current_h

def mainloop():
	''' main loop to show stuff on the screen '''
	while True:
		for event in pygame.event.get():
			if event.type == pygame.QUIT:
				pygame.quit()
		Text.show_text(enter="from_left")
		# clock.tick(60)
		pygame.display.update()


pygame.init()
w, h = monitor_size()
screen = pygame.display.set_mode((w - 100, h - 100), pygame.RESIZABLE)
clock = pygame.time.Clock()
mainloop()

Another example

import pygame



def start_window():

	pygame.init()
	GREEN = (0, 255, 0)
	# Text
	font = pygame.font.SysFont("Arial", 192)
	welcome = font.render("Pygame is great", 1, (GREEN))
	tw, th = welcome.get_size() # size of the text surface
	# Screen
	info = pygame.display.Info() # width and height
	w, h = info.current_w, info.current_h
	print(w, h)
	screen = pygame.display.set_mode((tw, th))
	clock = pygame.time.Clock()


	rx = 0
	forward = 1
	while True:
		screen.fill(0)
		for event in pygame.event.get():
			if event.type == pygame.QUIT or (
				event.type == pygame.KEYDOWN and
				event.key == pygame.K_ESCAPE):
				pygame.quit()
		if rx < tw and forward == 1:
			rx += 10
			screen.blit(welcome, (-tw + rx, 0))
			if rx == tw -1:
				forward = 0
		elif forward == 0:
			rx -= 10
			screen.blit(welcome, (-tw + rx, 0))
			if rx == 0:
				forward = 1

		clock.tick(60)
		pygame.display.update()
	return screen
