Question

我正在制作一个忍者游戏，其中忍者必须通过跳跃（按空格键）来躲避障碍物，但是跳跃动画太快，忍者无法跳过障碍物。我希望它跳得慢一点，让它越过障碍物，即使按下然后松开键，也能一直跳到394 y值。

请注意，我是初学者。

可能的解决方案，添加变量：

speedJump = 2 # play with this value, try to decrease and increase
ninjaDirect = None

在主循环中：

while True:  # main loop
  if ninjaDirect == "down":
    if player + 100 >= y:
      # we in middle of jump
      player.y += speedJump
    else: # we finish the jump
      ninjaDirect = None
      player.y = y
  ...
  for event in pygame.event.get():
  ...
    if event.type == pygame.KEYDOWN: #keydown
      if event.key == pygame.K_SPACE:
        if player.y > 100:
          ninjaDirect = "up"
          player.y -= speedJump
      else: ninjaDirect = "down"
    if event.type == pygame.KEYUP: #keyup
      if event.key == pygame.K_SPACE:
        ninjaDirect = "down"
  ...
