在pygame中計算重力的最佳方法是什麼？我基本上只需要它，所以當玩家按下「向上」時，角色就會跳起來。這是我目前為止的**(只有乙個白色螢幕和乙個移動的紅色塊)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.su***ce([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()
