Question

我的python游戏有问题，这是我的第一个项目。我收到一个错误（TypeError：期望的整数参数，浮点数）。当我插入用户定义的功能拍摄时，它开始出现。如何解决这个问题或使SuperMario图像与类一起拍摄圆形对象。谢谢:)）

import pygame
import time

pygame.init()

display_height = 600
display_width = 800

white = (255,255,255)

gameDisplay = pygame.display.set_mode((display_width, display_height))
pygame.display.set_caption('Igra1')
clock = pygame.time.Clock()

bg = pygame.image.load('background.jpg')
bg = pygame.transform.scale(bg,(800, 600))

Img_SuperMario = pygame.image.load('SuperMario.png')
SuperMario_width = 611
SuperMario_height = 611
Img_SuperMario = pygame.transform.scale(Img_SuperMario, (100, 100))

def shoot(xshoot):
    while xshoot < display_width:
        pygame.draw.circle(gameDisplay, white, (xshoot,50), 20 ,0)
        xshoot += 10

def SuperMario(x,y):
    gameDisplay.blit(Img_SuperMario,(x,y))

def gameloop():

x = (display_width * 0.1)
y = (display_height * 0.1)

x_change = 0
y_change = 0

game_exit = False

while not game_exit:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

        if event.type == pygame.KEYDOWN:
            if  event.key == pygame.K_LEFT:
                x_change = -5
            elif event.key == pygame.K_RIGHT:
                x_change = 5
            elif event.key == pygame.K_UP:
                y_change = -5
            elif event.key == pygame.K_DOWN:
                y_change = 5

        if event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT or event.key == pygame.K_DOWN or event.key == pygame.K_UP:
                x_change = 0
                y_change = 0


    if x == display_width - 100 or x == 0:
        x_change = 0

    if y == (display_height - 100) or y == 0:
        y_change = 0


    x += x_change
    y += y_change
    xshoot = x

    gameDisplay.fill(white)
    gameDisplay.blit(bg,(0,0))

    if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                while xshoot < display_width:
                    shoot(x)
    SuperMario(x,y)

    pygame.display.update()
    clock.tick(60)

gameloop()
pygame.quit()
quit()

Answer 1

pygame.draw.circle函数只接受整数，但您的x变量是浮点数。将xshoot变量转换为shoot函数中的整数，例如：

pygame.draw.circle(gameDisplay, white, (int(xshoot), 50), 20 ,0)

看起来您还需要更改主循环和while xshoot < display_width:函数中的shoot循环，但我不确定您想要实现的目标。

Answer 2

x = int((display_width * 0.1)) y = int((display_height * 0.1)) 尝试解析为int，也许会工作。

TypeError：预期的整数参数，浮点数，带pygame的python 3.6.3
