パイゲでこれをレイヤーするのに良い方法は何ですか？

Question

私はパイゲームの小さなプロジェクトに取り組んできました。これはオーバーヘッドの2Dゲームですが、プレーヤーがオブジェクトの後ろにいる場合は、プレーヤーの後ろに1つのレイヤーが必要です。プレイヤーがオブジェクトの前にいる場合は、それより前のレイヤーである必要があります。

for image, imagerect, imageypos in zip(blitimages, blitrects, blitypositions): 

    if realy < imageypos: 
     screen.blit(playerimage, playerimagerect) 
     screen.blit(image, imagerect) 
    if realy > imageypos: 
     screen.blit(image, imagerect) 
     screen.blit(playerimage, playerimagerect) 

    if realy == imageypos: 
     screen.blit(playerimage, playerimagerect) 
     screen.blit(image, imagerect) 

これは私が試したものですが、動作しません。常に正面にプレイヤーを表示しています。参考のため

：

blitrects = [house1imagerect, house2imagerect, rock1imagerect] 
blitimages = [house1image, house2image, rock1image] 
blitypositions = [house1y, house2y, rock1y] 

私は（それも高速です）、ほとんどこれを正しく行うための方法を必要としていますが、この方法では動作しなかった理由。私は答えのために必要な場合、コードのより多くの部分を投稿して喜んで、ちょうどそう言ってコメントを投稿！前もって感謝します！

Answer 1

私は（それ最も可能性の高い作品）このコードを試してみました

赤い面が理由です、緑が重複する緑の後ろにあります私はそれを少し透明に保ちました。レッドが追い抜くと、グリーンでブリットされます。コードはあなたと同じです。 IDKがなぜ機能しないのですか

import pygame 

pygame.init() 
clock = pygame.time.Clock() 

screen = pygame.display.set_mode((800,600)) 

surface1 = pygame.Surface((50,50)) 
surface1.fill((255,0,0)) 

surface2 = pygame.Surface((50,50)) 
surface2.fill((0,255,0)) 
surface2.set_alpha(196) 

surface1X = 0 
surface1Y = 275 

surface2X = 400 
surface2Y = 275 

x_change = 0 
y_change = 0 

speed = 2 

while True: 
    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 = -speed 
      if event.key == pygame.K_RIGHT: 
       x_change = speed 
      if event.key == pygame.K_UP: 
       y_change = -speed 
      if event.key == pygame.K_DOWN: 
       y_change = speed 

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

    surface1X += x_change 
    surface1Y += y_change 

    screen.fill((255,255,255)) 

    if (surface1X < surface2X): 
     screen.blit(surface1, (surface1X, surface1Y)) 
     screen.blit(surface2, (surface2X, surface2Y)) 

    else: 
     screen.blit(surface2, (surface2X, surface2Y)) 
     screen.blit(surface1, (surface1X, surface1Y)) 

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

Answer 2

Surfacesでの作業を中止してください。 PygameのSpriteクラスを使用してください。

次に、スプ​​ライトに_layer属性を与え、それらを管理するためにLayeredUpdatesグループを使用すると、グループがブリッティングの順序を処理します。スプライトの順序が_layer属性の値によって決定される方法

import pygame 
pygame.init() 
screen = pygame.display.set_mode((300, 300)) 

class Actor(pygame.sprite.Sprite): 
    def __init__(self, group, color, layer, pos): 
     self.image = pygame.Surface((30, 30)) 
     self.image.fill(color) 
     self.rect = self.image.get_rect(center=pos) 
     self._layer = layer 
     pygame.sprite.Sprite.__init__(self, group) 

group = pygame.sprite.LayeredUpdates() 
Actor(group, (255, 255, 255), 0, (100, 100)) 
Actor(group, (255, 0, 255), 1, (110, 110)) 
Actor(group, (0, 255, 255), 0, (120, 120)) 
Actor(group, (255, 255, 0), 3, (130, 130)) 
Actor(group, (0, 0, 255),  2, (140, 140)) 

run = True 
while run: 
    for e in pygame.event.get(): 
     if e.type ==pygame.QUIT: 
      run = False 
    screen.fill((0,0,0)) 
    group.update() 
    group.draw(screen) 
    pygame.display.flip()

は、ここでの例です。
