Как лучше всего рассчитать гравитацию в pygame? Мне в основном это просто нужно, чтобы, когда игрок нажимает «Вверх», персонаж прыгает. Вот мой код (просто белый экран с красным блоком, который движется)
import pygame
import random
# Define colors
black = ( 0, 0, 0)
white = ( 255, 255, 255)
green = ( 0, 255, 0)
red = ( 255, 0, 0)
#Classes
class Player(pygame.sprite.Sprite):
def __init__(self, color, width, height):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.Surface([width, height])
self.image.fill(color)
self.rect = self.image.get_rect()
def move(self, x_change, y_change):
self.rect.x += x_change
self.rect.y += y_change
#Lists
all_sprites_list = pygame.sprite.Group()
#Spawn player
player = Player(red,16,16)
all_sprites_list.add(player)
player.rect.x = 0
player.rect.y = 484
#Initalize
pygame.init()
#Set the width and height of the screen [width,height]
screen_height = 700
screen_width = 500
size=[screen_height,screen_width]
screen=pygame.display.set_mode(size)
#Name on top tab
pygame.display.set_caption("My Game")
#DONT CHANGE
done = False
clock=pygame.time.Clock()
#MAIN LOOP
while done == False:
for event in pygame.event.get(): # User did something
if event.type == pygame.QUIT: # If user clicked close
done = True # Quit
if event.type == pygame.KEYUP:
# If it is an arrow key, reset vector back to zero
if event.key == pygame.K_LEFT:
None
keyDown = pygame.key.get_pressed()
if keyDown[pygame.K_RIGHT]:
player.move(3, 0)
if keyDown[pygame.K_LEFT]:
player.move(-3, 0)
if keyDown[pygame.K_DOWN]:
player.move(0, 3)
if keyDown[pygame.K_UP]:
player.move(0,-3)
#If player hits side of screen, do this
if player.rect.x < 0:
player.rect.x = 0
if player.rect.x > 684:
player.rect.x = 684
if player.rect.y < 0:
player.rect.y = 0
if player.rect.y > 484:
player.rect.y = 484
#Clear screen
screen.fill(white)
#Drawing
all_sprites_list.draw(screen)
#FPS Lock
clock.tick(60)
#Update screen
pygame.display.flip()
# Close the window and quit.
pygame.quit()
