Question

过去一周左右我一直在研究太空入侵者类型的游戏，而且它的进展非常顺利，但出于某种原因，当我在我的Windows计算机上运行游戏时（我更愿意在其上编码）），大多数精灵都没有出现，或只是在他们在屏幕上朝某个方向移动时出现。当我在我的Mac上运行完全相同的代码时，所有内容都会完美地更新。这是一个已知的问题，pygame只是与Windows不相处？一切都在我的Mac上运行的事实使我认为这不是我的代码的问题，但以防万一，这是我的主循环：

dirty = []
score_label = font.render("Score: " + str(score), 1, (255,215,0))
level_label = font.render("Level: " + str(level), 1, (255,215,0))
screen.blit(background,(10,10),(10,10,330,30))
screen.blit(score_label,(10,10))
screen.blit(level_label,(200,10))
dirty.append((10,10,330,30))

# New level
if isEmpty(enemies):
    dirty.append((400,300,150,30))
    for i in bullets:
        dirty.append(i.pos)
        screen.blit(background,(i.pos[0],i.pos[1]),i.pos)
        bullets.remove(i)
    if pauseCounter == 40:
        screen.blit(background,(400,300),(400,300,150,30))
        pauseCounter = 0 
        jump = 30
        level+=1    
        for x in range(1,6):
            for y in range(11):
                enemies[x-1].append(Sprites.Enemy(enemy_values[6-x],(60*y,40*x),6-x))
        for x in range(len(enemies)):
            for e in enemies[x]:
                dirty.append(e.pos)
    else:
        upLevelLabel = levelFont.render("Next Level!",1,(255,215,0))
        screen.blit(upLevelLabel,(400,300))
        pauseCounter += 1

# Player input

if keys[K_a] and o.pos[0]-10 >= 0:
    o.speed = -10
    o.move()

    o.speed = 10
    o.move()
dirty.append(o.pos)
screen.blit(o.image,o.pos)

# Add bullets

            bullets.append(Sprites.Bullet(bullet,(o.pos[0]+28,o.pos[1])))

# Updates bunkers
for b in bunkers:
    screen.blit(b.image,b.pos)
    if b.health == 0:
        screen.blit(background,(b.pos[0],b.pos[1]),b.pos)

pygame.display.update(dirty)
clock.tick(30)
print clock.get_fps()

提前致谢！

Answer 1

也许你应该尝试：

dirty.append(Rect(x,y,width,height))

或

dirty.append(pygame.Rect(x,y,width,height))

请记住，您正在将一个矩形列表传递给pygame.display.update(dirty)，因此请尝试坚持使用pygame矩形

而不是：

dirty.append((x,y,width,height))

感谢furas，这是导致错误的部分更新！

为什么Pygame中的精灵不会在Windows 7中进入屏幕？
