我正在使用curses库在python中为终端创建Link to code游戏。每当未按任何键时, for (const [puppet, difficulty] of puppets) {
for (let i = 0; i < 3; i++) {
runPuppet(puppet, { difficulty, newGame: !!i });
}
}
都会返回错误。
这似乎是因为在这些帧期间光标不在屏幕的右下角(但在右下角),但是我根本不知道为什么它会移动。我正在打印的画布总是相同的尺寸(它完全由渲染Apple或Basket对象时替换的空间组成)。我尝试减小画布大小,但光标仍然移至该角。我也尝试设置stdscr.addstr()
,光标似乎在篮子的后面,但我的日志记录证明它仍然在那个角落。
使用curses的文件:
curses.leaveok(True)
(上面的代码运行良好,但是在import random
import time
import curses
from apple_season.basket import Basket
from apple_season.apple import Apple
from apple_season.coords import Canvas
def main(stdscr):
curses.curs_set(1) # so i can see where the cursor is
dims = [curses.COLS - 1, curses.LINES - 1] # pylint: disable=no-member
stdscr.nodelay(True)
stdscr.leaveok(True)
key=""
stdscr.clear()
canvas = Canvas(*dims)
basket = Basket(canvas)
apples = []
i = 0
def finished_apples():
if len(apples) <= 100:
return False
else:
for apple in apples:
if not apple.has_fallen:
return False
return True
while not finished_apples():
if len(apples) <= 100: # don't make more if there are already 100
# decide whether or not to create new apple (1/100 chance per frame)
num = random.randint(0, 100)
if num == 25:
apples.append(Apple(canvas))
try:
key = stdscr.getkey()
stdscr.clear()
# pick up keyboard inputs
# quit option
if str(key) == "q":
break
# right arrow
elif str(key) == "KEY_RIGHT":
basket.move('right')
# left arrow
elif str(key) == "KEY_LEFT":
basket.move('left')
except Exception:
pass
# render objects - alters canvas to display them
for apple in apples:
if apple.has_fallen:
apple.render()
else:
if '.0' not in str(i / 2): # check if i is even (drop every other frame)
apple.fall()
apple.render()
basket.render()
try:
stdscr.addstr(canvas.display)
except Exception:
pass
stdscr.refresh()
i += 1
time.sleep(0.01)
if __name__ == "__main__":
curses.wrapper(main)
不起作用时(即在没有按键的情况下,它什么也不做)
有趣的是,当它只是篮子或苹果时,不会发生这种情况。
要查看所有代码:this。
答案 0 :(得分:0)
我将stdscr.clear()放在try和except块中,这使得该代码仅在按下键时才执行,因此由于我试图一次显示多个帧而使终端溢出。 / p>
