class
pyskool.mutable.
Bike
(x, y)¶ Represents the portion of the tree that may or may not have a bike chained to it.
Parameters: - x – The x-coordinate of the bike-on-a-tree image.
- y – The y-coordinate of the bike-on-a-tree image.
-
build_images
()¶ Build the images for the bike. This method is called after rescaling the screen or loading a saved game.
-
chain
()¶ Return a 2-tuple containing a list of the images to use when the bike is chained to the tree, and the coordinates of the images.
-
get_images
()¶ Return a 2-tuple containing a list of images of the current state of the bike, and the coordinates at which to draw the bike.
-
set_images
(unchained_images, chained_images)¶ Define the images to use for the bike-on-a-tree.
Parameters: - unchained_images – A list of images to use when the bike is not chained to the tree.
- chained_images – A list of images to use when the bike is chained to the tree.
-
unchain
()¶ Return a 3-tuple containing a list of the images to use when the bike is not chained to the tree, and the coordinates of the images.
-
class
pyskool.mutable.
Cup
(cup_id, coords, water_id, sherry_id)¶ A cup that may be empty or filled with water or sherry.
Parameters: - cup_id – The ID of the cup.
- coords – The coordinates of the cup.
- water_id – The ID of the liquid for which the water-filled image should be used.
- sherry_id – The ID of the liquid for which the sherry-filled image should be used.
-
build_images
()¶ Build the images for the cup. This method is called after rescaling the screen or loading a saved game.
-
fill
(contents)¶ Fill the cup with a liquid, or empty it.
Parameters: contents – The liquid to fill the cup with, or None to empty it. Returns: The images for and location of the cup.
-
get_images
()¶ Return a 2-tuple containing a list of images of the current state of the cup, and the coordinates at which to draw the cup.
-
insert_frog
(frog)¶ Insert a frog into the cup.
Parameters: frog ( Frog
) – The frog.
-
is_empty
()¶ Return whether the cup is empty (contains no liquid or frogs).
-
remove_frog
(frog)¶ Remove a frog from the cup.
Parameters: frog ( Frog
) – The frog.
-
set_images
(empty_images, water_images, sherry_images)¶ Define the images to use for the cup.
Parameters: - empty_images – A list of images of the cup when empty.
- water_images – A list of images of the cup when filled with water.
- sherry_images – A list of images of the cup when filled with sherry.
-
class
pyskool.mutable.
Flashable
(x, y, images, inverse_images, score=0)¶ Abstract superclass for objects that flash (shields and the safe).
Parameters: - x – The x-coordinate of the object.
- y – The y-coordinate of the object.
- images – A list of normal images of the object.
- inverse_images – A list of inverse images of the object.
- score – The points awarded for hitting the object.
-
build_images
()¶ Build the images for this object. This method is called after rescaling the screen or loading a saved game.
-
flash
()¶ Mark the object as flashing.
-
get_images
(inverse)¶ Return a 2-tuple containing a list of images of the object, and the coordinates at which it should be drawn.
Parameters: inverse – If True, return the inverse images; otherwise return the normal images.
-
unflash
()¶ Mark the object as not flashing.
-
class
pyskool.mutable.
Safe
(x, y, images, inverse_images, score=0)¶ A safe that will flash or unflash when hit.
-
class
pyskool.mutable.
Shield
(x, y, images, inverse_images, score=0)¶ A shield that will flash or unflash when hit.
