Token

Token¶

class miniworldmaker.tokens.token.Token(position=(0, 0))[source]¶

Tokens are objects on your board. Tokens can move around the board and have sensors to detect other tokens.

The appearance of a token is determined by its costume.

Examples

Create a token:

from miniworldmaker import *

board = Board()
board.size = (100,60)
Token(position=(10, 10))

board.run()

Output:

Create a token with an image:

from miniworldmaker import *

board = Board(100,60)
token = Token((10, 10))
token.add_costume("images/player.png")

board.run()

Output:

import miniworldmaker

class MyToken(miniworldmaker.Token):

    def on_setup(self):
        self.add_costume("images/player.png")

board = Board(100,60)
my_token = MyToken(position = (40,130))
board.run()

Output:

Create a Token at current mouse position:

from miniworldmaker import *

board = Board()

@board.register
def act(self):
    Token(self.get_mouse_position())

board.run()

board.speed = 30
costume1 = token.add_costume((255,255,0))
costume2 = token.add_costume((255,0,255))
@token.register
def act(self):
    if self.costume == costume1:
        self.switch_costume(costume2)
    else:
        self.switch_costume(costume1)

board.run()

Output:

Create multiple costumes and switch between costumes

Returns:: The new costume.
Return type:: Costume

add_costumes(sources)[source]¶

Adds multiple costumes

Return type:: Costume

animate(speed=10)[source]¶

animate_costume(costume, speed=10)[source]¶

animate_loop(speed=10)[source]¶

Animates a costume with a looping animation

Switches through all costume-images every speed-frame.

Examples

from miniworldmaker import *

board = Board(columns=280, rows=100)
robo = Token(position=(0, 0))
robo.costume.add_images(["images/1.png", "images/2.png","images/3.png","images/4.png"])
robo.size = (99, 99)
robo.animate_loop()
board.run()

Parameters:: speed (int, optional) – Every speed frame, the image is switched. Defaults to 10.

property border¶

The border-size of token.

The value is 0, if token has no border.

Note

You can also set border with costume.border or you can set the border with board.default_border

Examples

Set border of token:

from miniworldmaker import *

board = Board(210,80)
board.default_border_color = (0,0, 255)
board.default_border = 1

t = Token((10,10)) # default-border and color from bord
t.add_costume("images/player.png")

t2 = Token ((60, 10)) # overwrites default border values
t2.add_costume("images/player.png")
t2.border_color = (0,255, 0)
t2.border = 5

t3 = Token ((110, 10)) # removes border
t3.add_costume("images/player.png")
t3.border = None

board.run()

Output:

property border_color¶

border color of token.

The border-color is a rgba value, for example (255, 0, 0) for red, (0, 255, 0) for green and (255, 0, 0, 100).

If the color-value has 4 values, the last value defines the transparency:

0: Full transparent,
255: No transparency

Note

You must also set Token.border to a value > 0

Aliases: Token.stroke_color

Examples

See Token.border

bounce_from_border(borders)[source]¶

Examples

from miniworldmaker import *
import random

board = Board(150, 150)
token = Token((50,50))

property is_flipped: bool¶

If a token is flipped, it is mirrored via the y-axis. You can use this property in 2d-plattformers to change the direction of token.

Note

It may be necessary to set is_rotatable = True

Examples

Flip a costume after 100 frames.

from miniworldmaker import *

board = Board(100,100)

board = Board()

t1 = Token((100,100))
t1.add_costume("images/alien1.png")

t2 = Token((200,200))
t2.add_costume("images/alien1.png")
t2.is_rotatable = False

@t1.register
def act(self):
    self.move()

Examples

token1 = miniworldmaker.Token(position = (2, 2) )
token1.add_costume((100,0,100,100))

@token1.register
