複数の矩形を1つずつクリックして移動する

Question

私は3つの矩形を持つ2つのリストを持っています。私は変数selected1とselected2に各リストから3つのrectを割り当て、それらの間のギャップを保ちながら別々に上下に2つのrectの行を移動できますか？私は初心者であり、そのような構築されたコードがこの作業を処理できるかどうかはわかりません。

import pygame 

# === CONSTANS === 
white = (255, 255, 255) 
black = (0, 0, 0) 
red = (255, 0, 0) 
blue = (0, 0, 255) 
green = (0, 102, 0) 
yellow = (255, 204, 0) 
grid_color = (224, 224, 224) 

width = 1200 
height = 720 

k = 10 

screen = pygame.display.set_mode((width, height)) 
screen_rect = screen.get_rect() 

# --- objects --- 

G_x = 10 # stripe width 
x = 2 

stripes_x1 = [] 
stripes_x2 = [] 

G1_pos_x = 122 
G2_pos_x = 367 
G1_pos_y = 0 
G2_pos_y = 0 

G1_y = 60*x 
G2_y = 75*x 

G1_start = G1_pos_y + height - G1_y 
G2_start = G2_pos_y + height - G2_y 

a = 166 
b = 222 
for x in range(3): 
    gap = a*x 
    gap2 = b*x 
    stripes_x1.append(pygame.Rect(G1_pos_x, (G1_start - 6*k) - gap, G_x, G1_y)) 
    stripes_x2.append(pygame.Rect(G2_pos_x, (G2_start - 6*k) - gap2, G_x, G2_y)) 

selected1 = None 
selected2 = None 

# --- mainloop --- 

clock = pygame.time.Clock() 
is_running = True 

while is_running: 

    for event in pygame.event.get(): 

     # --- global events --- 

     if event.type == pygame.QUIT: 
      is_running = False 

     if event.type == pygame.KEYDOWN: 
      if event.key == pygame.K_ESCAPE: 
       is_running = False 

     if event.type == pygame.MOUSEBUTTONDOWN: 
      if event.button == 1: 
       for i, r in enumerate(stripes_x1): 
        if r.collidepoint(event.pos): 
         selected1 = i 
         selected_offset_y = r.y - event.pos[1] 
     if event.type == pygame.MOUSEMOTION: 
      if selected1 is not None: # selected can be `0` so `is not None` is required 
       stripes_x1[selected1].y = event.pos[1] + selected_offset_y 

     if event.type == pygame.MOUSEBUTTONUP: 
      if event.button == 1: 
       selected1 = None 

     if event.type == pygame.MOUSEBUTTONDOWN: 
      if event.button == 1: 
       for j, r in enumerate(stripes_x2): 
        if r.collidepoint(event.pos): 
         selected2 = j 
         selected_offset_y = r.y - event.pos[1] 
     if event.type == pygame.MOUSEMOTION: 
      if selected2 is not None: # selected can be `0` so `is not None` is required 
       stripes_x2[selected2].y = event.pos[1] + selected_offset_y 

     if event.type == pygame.MOUSEBUTTONUP: 
      if event.button == 1: 
       selected2 = None

     ''' 
     button.handle_event(event) 
     '''

    screen.fill(white) 
    for i in range(width): 
     grid_x = k * i 
     grid_y = k * i 

     pygame.draw.line(screen, grid_color, (grid_x, 0), (grid_x, height), 1) 
     pygame.draw.line(screen, grid_color, (0, grid_y), (width, grid_y), 1) 
     pygame.draw.line(screen, black, (6 * k, height - 6 * k), (width - 6 * k, height - 6 * k), 3) 
     pygame.draw.line(screen, black, (6 * k, height - 6 * k), (6 * k, 0 * k), 3) 
    # draw rect 
    for r in stripes_x1: 
     pygame.draw.rect(screen, green, r) 
    for s in stripes_x2: 
     pygame.draw.rect(screen, green, s) 


    pygame.display.update() 

    clock.tick(60) 
pygame.quit()

同時にrectsを移動するには、リストでそれらを置くことができるし、1つの矩形を選択した場合は、最後のマウスからMOUSEMOTIONイベント（相対位置のrel属性の助けを借りて、それらすべてを動かしますイベント）。ここでは、最小限の例です：

import sys 
import pygame as pg 


BLACK = pg.Color('black') 
RECT_COLOR = pg.Color(78, 140, 200) 


def main(): 
    screen = pg.display.set_mode((640, 480)) 
    clock = pg.time.Clock() 
    rect_list = [pg.Rect(100, 100+y, 20, 80) for y in range(0, 241, 120)] 
    selected = False 
    done = False 

    while not done: 
     for event in pg.event.get(): 
      if event.type == pg.QUIT: 
       done = True 
      elif event.type == pg.MOUSEBUTTONDOWN: 
       for rect in rect_list: 
        if rect.collidepoint(event.pos): 
         selected = True 
      elif event.type == pg.MOUSEBUTTONUP: 
       selected = False 
      elif event.type == pg.MOUSEMOTION: 
       if selected: 
        for rect in rect_list: 
         rect.y += event.rel[1] 

     screen.fill(BLACK) 
     for rect in rect_list: 
      pg.draw.rect(screen, RECT_COLOR, rect) 

     pg.display.flip() 
     clock.tick(30) 


if __name__ == '__main__': 
    pg.init() 
    main() 
    pg.quit() 
    sys.exit()
