Tokens -> Shapes

Shape

Base class for shapes

class miniworldmaker.tokens.token_plugins.shapes.shapes.Shape(position=None)

Shape is the parent class for various geometric objects that can be created.

Each geometric object has the following properties:

• border: The border thickness of the object.

• is_filled: True/False if the object should be filled.

• fill_color: The fill color of the object

• border_color: The border color of the object.

Point

class miniworldmaker.tokens.token_plugins.shapes.shapes.Point(position)

A point is a Circle with Radius 1

__init__(position)

Init a Point at specified position

Circle

class miniworldmaker.tokens.token_plugins.shapes.shapes.Circle(position=(0, 0), radius=10)

A circular shape, definied by position and radius

Parameters:

• position – The position as 2-tuple. The circle is created with its center at the position

• radius – The radius of the circle

Examples

Create a circle at center position (200,100) with radius 20:

Circle((200, 100), 20)

Create a circle at topleft position

miniworldmaker.Circle.from_topleft((100,100),50)

classmethod from_center(position, radius)

Creates a circle with center at position

classmethod from_topleft(position, radius)

Creates a circle with topleft at position

new_costume()

property radius

The radius of the circle. If you change the circle-size (e.g. with self.size = (x, y), the radius value will be changed too.

set_physics_default_values()

Ellipse

class miniworldmaker.tokens.token_plugins.shapes.shapes.Ellipse(position=(0, 0), width=10, height=10)

An elliptic shape.

Parameters:

• position – The position as 2-tuple. The ellipse is created at topleft position

• width – The width of the ellipse

• height – The height of the ellipse

Examples

Create an ellipse at topleft position (200,100) with width 20 and height 30

Ellipse((200, 100), 20, 30)

Create an ellipse at center-position (200,100) width width 10 and height 10

miniworldmaker.Ellipse.from_center((100,100),10, 10)

(Alternative) Create an ellipse at center-position (200,100) with width 10 and height 10

e = miniworldmaker.Ellipse((100,100),10, 10)
e.center = e.position

check_arguments(position, width, height)

classmethod from_center(position, width, height)

Creates an ellipse with center at position

classmethod from_topleft(position, width, height)

Creates an ellipse with topleft at position

Line

class miniworldmaker.tokens.token_plugins.shapes.shapes.Line(start_position, end_position)

A Line-Shape defined by start_position and end_position.

Parameters:

• start_position – The start_position as 2-tuple.

• end_position – The end_position as 2-tuple.

Examples

Create a line from (200, 100) to (400, 100)

Line((200, 100), (400,100))

Create a line from (200, 100) to (400, 100)

l = Line((200, 100), (400,100))
l.border = 2

property border

-> see border

property direction

Directions are handled exactly as in the Scratch programming language, see: Scratch Wiki

The default direction is 0°. All tokens are looking "up"

Values for Direction

• 0° or "up": up

• 90° or "right": Move right

• -90° or "left": Move left

• 180° or "down": Move down

• "forward": Current direction

Sets direction of the token.

You can use an integer or a string to describe the direction

Options

• 0, "up" - Look up

• 90, "right", - Look right

• -90, "left", - Look left

• -180, 180, "down" - Look down

Examples

Move in a direction with WASD-Keys

def on_key_down(self, keys):
    if "W" in keys:
        self.direction = "up"
    elif "S" in keys:
        self.direction = "down"
    elif "A" in keys:
        self.direction = "left"
    elif "D" in keys:
        self.direction = "right"
    self.move()

Move 45°:

from miniworldmaker import *

board = Board(100, 100)
c = Circle ((50,50), 10)

@c.register
def act(self):
    c.direction = 45
    c.move()

board.run()

Move -45°:

from miniworldmaker import *

board = Board(100, 100)
c = Circle ((50,50), 10)

@c.register
def act(self):
    c.direction = -45
    c.move()

board.run()

Rectangle

class miniworldmaker.tokens.token_plugins.shapes.shapes.Rectangle(topleft=(0, 0), width=10, height=10)

A rectangular shape defined by position, width and height

Parameters:

• topleft – Topleft Position of Rect

• height – The height of the rect

• width – The width of the rect

Examples

Create a rect with the topleft position (200, 100), the width 20 and the height 10

Polygon

class miniworldmaker.tokens.token_plugins.shapes.shapes.Polygon(*args, **kwargs)

A Polygon-Shape.

Parameters:

point-list – A list of points

Examples

Example Creation of a polygon

>>> Polygon([(200, 100), (400,100), (0, 0)])
