pygame.mask.from_su***ce(self,image)
對的非透明部分做標記
pygame.sprite.spritecollide(b, enemies, false, pygame.sprite.collide_mask)
完美檢測碰撞
me.rect.midtop，子彈生成在飛機的中間的頂部
if not(delay % 10):
bullet1[bullet1_index].reset(me.rect.midtop)
bullet1_index = (bullet1_index + 1) % bullet1_num
每10幀繪製一枚子彈，子彈索引0~3，
按照子彈的飛行速度，4個子彈差不多乙個螢幕的高度
pygame.draw.line(screen, black, \
(each.rect.left, each.rect.top - 5), \
(each.rect.right, each.rect.top - 5), \
2)繪製血槽的底槽，黑色，放在飛機的上方5個畫素的位置，2個畫素的寬度
energy_remain = each.energy / enemy.bigenemy.energy
if energy_remain > 0.2:
energy_color = green
else:
energy_color = red
pygame.draw.line(screen, energy_color, \
(each.rect.left, each.rect.top - 5), \
(each.rect.left + each.rect.width * energy_remain, \
each.rect.top - 5), 2)
如果energy（血量）大於百分之20，血條顏色為綠色，低於則為紅色
起點(each.rect.left, each.rect.top - 5)
終點(each.rect.left + each.rect.width * energy_remain, \each.rect.top - 5)
