Inheritance in CodeCraft

Seeds is a CodeCraft class, it's object, such as s upon creation, is planted(show up) at location(x,z), it's brown color. it has methods plant(), when we call s.plant(), another 'brown seed' will show up at the right side(shift right 4 blocks)

Another method s.grow() , the 'seed' will grow taller(green color) and sprout.

class Seeds:
  def __init__(self, x,z):
    self.x = x
    self.z = z
    self.plant()    

  def plant(self):
    block(self.x, 1, self.z, 'box_brown')
    self.x += 4

  def grow(self):
    for j in range(5):
      game.set_timer(j/2, block, self.x-7, j, self.z, 'box_green')
    game.set_timer(3.5, block,self.x-8, 5, self.z, 'box_lime')
    game.set_timer(4, block,self.x-6, 5, self.z, 'box_lime')

# new object
s = Seeds(0, -20)       # a seed at x:0
s.grow()                # it grows

s.plant()               # another seed at x:4
s.grow()                # it grows

Corn

Corn is a subclass of Seeds, it inherits every thing in Seeds, and has one more method growCorn(), a ordinary 'seed' will grown bigger and into a yellow corn.

# child, Corn
class Corn(Seeds):
  def growCorn(self):
    self.grow()
    game.set_timer(4.5, block,self.x-7, 5, self.z, 'box_green')
    game.set_timer(5, block,self.x-7, 6, self.z, 'box_green')
    game.set_timer(5, block,self.x-9, 6, self.z, 'box_lime')
    game.set_timer(5, block,self.x-5, 6, self.z, 'box_lime')  
    for j in range(5):
      game.set_timer(6+j/2, block, self.x-7, j+7, self.z, 'box_yellow')

# new object
c = Corn(0, -10)
c.grow()

for i in range(10):
  c.plant()
  c.growCorn()

Flower

Flower is another subclass of Seeds, it overrides Seeds' methodinitto accept another argumentcolor`;

it's method growFlower(), a object will grow bigger and into a flower with a special color.

# child, Flower
class Flower(Seeds):
  def __init__(self, x,z, material):
    self.x = x
    self.z = z
    self.m = material

  def growFlower(self,m):
    self.grow()
    game.set_timer(4.5, block,self.x-7, 5, self.z, 'box_green')
    game.set_timer(5, block,self.x-7, 6, self.z, 'box_green')
    game.set_timer(5, block,self.x-9, 6, self.z, 'box_lime')
    game.set_timer(5, block,self.x-5, 6, self.z, 'box_lime')

    game.set_timer(6, block,self.x-7, 7, self.z, m)
    game.set_timer(6, block,self.x-7, 9, self.z,m)
    game.set_timer(6, block,self.x-8, 8, self.z, m)
    game.set_timer(6, block,self.x-6, 8, self.z, m)

In Flower, __init__ method overrides the parent's, other than x,z, it needs one more argument, material(for flower color)

# some flowers      
s = Flower(-10, -20)
print(s)
s.grow()

s.growFlower('linen_purple')
for i in range(4):
  s.plant()
  s.growFlower('linen_purple')

# flowers can have different colors
s.plant()
s.growFlower('linen_yellow')
s.plant()
s.growFlower('linen_red')
s.plant()
s.growFlower('box_pink')
