python(pygame)中动画速度的问题 [英] Problem in speed of animation in python(pygame)
本文介绍了python(pygame)中动画速度的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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.
I am making a ninja game in which a ninja has to dodge obstacle by jumping(pressing spacebar), but the jump animation is too fast and the ninja is not able to jump beyond the obstacles. I want that it jumps a little slowly so as to make it jump beyond the obstacles, and goes till the 394 y value even if the key is released after pressing and then come down.
请注意，我是初学者.

推荐答案
可能的解决方案，添加变量:
possible solution, add a varibles:
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"
...
