如何在 PyGame 中拖动 2 个以上的图像? [英] How can I drag more than 2 images in PyGame?

问题描述

我有这个代码，但我想用其他 4 张图片制作它?

 导入 pygame从 pygame.locals 导入 *pygame.display.init()屏幕 = pygame.display.set_mode((1143,677))img = pygame.image.load(r"C:\Users\ga-sa\Downloads\As.png")img1 = pygame.image.load(r"C:\Users\ga-sa\Downloads\03.png")imgPos = img.get_rect(topleft = (20, 20))imgPos1 = img1.get_rect(topleft = (60, 20))current_image = 无左按钮 = 0而 1:对于 pygame.event.get() 中的 e:如果 e.type == 退出:pygame.quit()退出(0)如果 e.type == pygame.MOUSEBUTTONDOWN:如果 imgPos.collidepoint(e.pos):current_image = 0elif imgPos1.collidepoint(e.pos):current_image = 1别的:current_image = 无如果 e.type == MOUSEMOTION:如果 e.buttons[LeftButton]:rel = e.rel如果 current_image == 0:imgPos.x += rel[0]imgPos.y += rel[1]elif current_image == 1:imgPos1.x += rel[0]imgPos1.y += rel[1]屏幕填充(0)screen.blit(img, imgPos)screen.blit (img1, imgPos1)pygame.display.flip()pygame.time.delay(30)

所以这是我的代码，我想放 4 张图片，而不是只有两张图片，我想放更多图片，但它是一个布尔值，所以是 0 或 1

解决方案

创建一个包含 4 个图像的列表:

images = [img1, img2, img3, img4]

创建图像矩形列表:

img_rects = [images[i].get_rect(topleft = (20+40*i, 20)) for i in range(len(images))]

使用

导入pygame从 pygame.locals 导入 *pygame.display.init()屏幕 = pygame.display.set_mode((1143, 677))img1 = pygame.image.load(r"C:\Users\ga-sa\Downloads\As.png")img2 = pygame.image.load(r"C:\Users\ga-sa\Downloads\03.png")img3 = pygame.image.load(r"C:\Users\ga-sa\Downloads\As.png")img4 = pygame.image.load(r"C:\Users\ga-sa\Downloads\03.png")图片 = [img1, img2, img3, img4]current_image = -1img_rects = [images[i].get_rect(topleft = (20+40*i, 20)) for i in range(len(images))]左按钮 = 0而 1:对于 pygame.event.get() 中的 e:如果 e.type == 退出:pygame.quit()退出(0)如果 e.type == pygame.MOUSEBUTTONDOWN:mouse_rect = pygame.Rect(e.pos, (1, 1))current_image = mouse_rect.collidelist(img_rects)如果 e.type == MOUSEMOTION:如果 e.buttons[LeftButton]:rel = e.rel如果 0 <= current_image <镜头(图像):img_rects[current_image].x += rel[0]img_rects[current_image].y += rel[1]屏幕填充(0)对于我在范围内(len(图像)):screen.blit(图像[i]，img_rects[i])pygame.display.flip()pygame.time.delay(30)

i have this code but i wanna make this with other 4 images?

 import pygame
 from pygame.locals import *

 pygame.display.init()
 screen = pygame.display.set_mode((1143,677 ))

img = pygame.image.load(r"C:\Users\ga-sa\Downloads\As.png")
img1 = pygame.image.load(r"C:\Users\ga-sa\Downloads\03.png")
imgPos = img.get_rect(topleft = (20, 20))
imgPos1 = img1.get_rect(topleft = (60, 20))
current_image = None

 LeftButton = 0
while 1:
for e in pygame.event.get():
    if e.type == QUIT:
        pygame.quit()
        exit(0)

    if e.type == pygame.MOUSEBUTTONDOWN:
        if imgPos.collidepoint(e.pos):
            current_image = 0
        elif imgPos1.collidepoint(e.pos):
            current_image = 1
        else: 
            current_image = None

    if e.type == MOUSEMOTION:
        if e.buttons[LeftButton]:
            rel = e.rel
            if current_image == 0:
                imgPos.x += rel[0]
                imgPos.y += rel[1]
            elif current_image == 1:
                imgPos1.x += rel[0]
                imgPos1.y += rel[1]

screen.fill(0)
screen.blit(img, imgPos)
screen.blit (img1, imgPos1)
pygame.display.flip()
pygame.time.delay(30)

so this my code i want to put 4 image , instead only two images , i would like to put more images but is a boolean so is 0 or 1

解决方案

Create a list of 4 images:

images = [img1, img2, img3, img4]

Create a list of image rectangles:

img_rects = [images[i].get_rect(topleft = (20+40*i, 20)) for i in range(len(images))]

Use pygame.Rect.collidelist to find the image which is clicked:

if e.type == pygame.MOUSEBUTTONDOWN:
    mouse_rect = pygame.Rect(e.pos, (1, 1))
    current_image = mouse_rect.collidelist(img_rects)

Draw the current_image:

if e.type == MOUSEMOTION:
    if e.buttons[LeftButton]:
        rel = e.rel
        if 0 <= current_image < len(images):
            img_rects[current_image].x += rel[0]
            img_rects[current_image].y += rel[1]

Draw the images in a loop:

for i in range(len(images)):
    screen.blit(imgages[i], img_rects[i])

Minimal example:

import pygame
from pygame.locals import *

pygame.display.init()
screen = pygame.display.set_mode((1143, 677))

img1 = pygame.image.load(r"C:\Users\ga-sa\Downloads\As.png")
img2 = pygame.image.load(r"C:\Users\ga-sa\Downloads\03.png")
img3 = pygame.image.load(r"C:\Users\ga-sa\Downloads\As.png")
img4 = pygame.image.load(r"C:\Users\ga-sa\Downloads\03.png")

images = [img1, img2, img3, img4]

current_image = -1
img_rects = [images[i].get_rect(topleft = (20+40*i, 20)) for i in range(len(images))]

LeftButton = 0
while 1:
    for e in pygame.event.get():
        if e.type == QUIT:
            pygame.quit()
            exit(0)

        if e.type == pygame.MOUSEBUTTONDOWN:
            mouse_rect = pygame.Rect(e.pos, (1, 1))
            current_image = mouse_rect.collidelist(img_rects)

        if e.type == MOUSEMOTION:
            if e.buttons[LeftButton]:
                rel = e.rel
                if 0 <= current_image < len(images):
                    img_rects[current_image].x += rel[0]
                    img_rects[current_image].y += rel[1]

    screen.fill(0)
    for i in range(len(images)):
        screen.blit(images[i], img_rects[i])
    pygame.display.flip()
    pygame.time.delay(30)
