TypeError：当我尝试在pygame中跳转时，Rect参数无效

问题描述

我想跳，但出现错误：

TypeError：Rect参数无效

顺便说一下，我是从youtube中学到的。

import pygame
import random
pygame.init() 

screen = pygame.display.set_mode((500,500))

pygame.display.set_caption("First game!")


gubbe_x = 50
gubbe_y = 50
gubbe_vel = 0.1
gubbe_width = 40
gubbe_height = 50
isjump = False
jumpCount = 10

run = True
running = True 
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    #write code in forloop line
    pygame.draw.rect(screen,(255,0),(gubbe_x,gubbe_y,gubbe_width,gubbe_height))
    keys = pygame.key.get_pressed()

    if keys[pygame.K_RIGHT] and gubbe_x < 500 - gubbe_width - gubbe_vel:
        gubbe_x += gubbe_vel
    if keys[pygame.K_LEFT] and gubbe_x > gubbe_vel:
        gubbe_x -= gubbe_vel
    if not (isjump):
        if keys[pygame.K_UP] and gubbe_y > gubbe_vel:
            gubbe_y -= gubbe_vel
        if keys[pygame.K_DOWN] and gubbe_y < 500 - gubbe_height - gubbe_vel:
            gubbe_y += gubbe_vel
        
        if keys[pygame.K_SPACE]:
            isjump = True
        
    else:
        if jumpCount >= -10:
            gubbe_y -= jumpCount ** 1.5 * 0.05
            jumpCount -= 1
        else:
            isjump == False
            jumpCount = 10


    
    pygame.display.update()
    screen.fill((0,0))

pygame.quit()

解决方法

-1 ** 1.5的结果是一个复数。您最有可能尝试执行以下操作：

~~gubbe_y -= jumpCount ** 1.5 * 0.05~~

gubbe_y -= (1 if jumpCount > 0 else -1) *  abs(jumpCount) ** 1.5  * 0.05

在这种情况下，还有一个错别字：

~~isjump == False~~

isjump = False

查看示例：

while run:
    # [...]

    if not (isjump):
        if keys[pygame.K_UP] and gubbe_y > gubbe_vel:
            gubbe_y -= gubbe_vel
        if keys[pygame.K_DOWN] and gubbe_y < 500 - gubbe_height - gubbe_vel:
            gubbe_y += gubbe_vel
        
        if keys[pygame.K_SPACE]:
            isjump = True
        
    else:
        if jumpCount >= -10:
            gubbe_y -= (1 if jumpCount > 0 else -1) *  abs(jumpCount) ** 1.5  * 0.05
            jumpCount -= 1
        else:
            isjump = False
            jumpCount = 10

    # [...]
