使用函数关闭pygame窗口 [英] Using a function closes pygame window
问题描述
以下是 String
类.在我的主循环中使用此类的draw函数可以立即关闭游戏,而不会出现任何错误,并且只要我不添加它,游戏就可以正常运行.它确实给了我以下警告.
The following is the String
class. Using the draw function from this class in my main loop immediately closes the game without any errors and as long i dont include it, the game runs fine. It does give me the following warning.
Warning (from warnings module):
File "C:\Users\rahul\OneDrive\Documents\A level python codes\shootingGame.py", line 44
D.blit(self.player, (self.pos[0], self.pos[1]))
DeprecationWarning: an integer is required (got type float). Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python.
import math, sys, os, pygame
from pygame.locals import *
pygame.init()
win = pygame.display
D = win.set_mode((1200, 600))
class String:
def __init__(self, x, y):
self.pos = [x, y]
self.dx = 0
self.dy = 0
self.string = pygame.Surface((1, 1)).convert_alpha()
self.string.fill((0, 255, 0))
def draw(self):
angle = pygame.transform.rotate(self.string, (player.orbital_angle))
length = math.hypot(self.dx, self.dy)
self.string = pygame.Surface((3, length))
D.blit(angle, (self.pos[0], self.pos[1]))
string = String(600, 300)
While True:
string.draw()
起初我在differnet函数的 draw
函数中拥有所有内容,但在调试时有点混乱.特别是,这是导致 draw()
中的最后两行崩溃的窗口,即
I initially had everything in draw
function in differnet functions but it got a bit messy while debugging.Specifically, it is the last two lines in draw()
that's causing the window to crash i.e
self.string = pygame.Surface((3, length))
D.blit(angle, (self.pos[0], self.pos[1]))
推荐答案
The position (dest) argument to pygame.Surface.blit()
is ought to be a tuple of 2 integral numbers.
In your case self.pos[0]
and/or self.pos[1]
seems to be a floating point number.
You can get rid of the warning by rounding the floating point coordinates to integral coordinates (round
):
D.blit(self.player, (round(self.pos[0]), round(self.pos[1])))
为了完整起见,必须提到该参数也可以是矩形.具有四个组成部分(左,顶部,宽度,高度)的元组.
For the sake of completeness it has to be mentioned that the argument can also be a rectangle. A tuple with the 4 components (left, top, width, height).
此外,您还创建了一个具有整数长度的Surface,并且必须在(重新)创建它之后旋转该表面:
Furthermore you have create a Surface with an integral length and you have to rotate the surface after it is (re)created:
class String:
# [...]
def draw(self):
# compute INTEGRAL length
length = math.hypot(self.dx, self.dy)
length = max(1, int(length))
# create surface
self.string = pygame.Surface((1, length)).convert_alpha()
self.string.fill((0, 255, 0))
# roatet surface
angle = pygame.transform.rotate(self.string, player.orbital_angle)
# blit rotated surface
D.blit(angle, (round(self.pos[0]), round(self.pos[1])))
