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

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:

Create a Token with image
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

Create a Token at current mouse position:

from miniworldmaker import *

board = Board()

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

board.run()
Create a token at mouse position

Parameters:

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

property board_sensor
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:

Set borders
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

get_local_rect()[source]
Return type:

Rect

get_rect()[source]

Gets the rect of the token.

If a camera is used, the local rect is written.

Returns:

property height

The height of the token in pixels.

When the height of a token is changed, the width is scaled proportionally.

Examples

Create a token and scale width/height proportionally:

from miniworldmaker import *

board = Board(800,400)

def create_token(x, y):
t = Token()
t.position = (x, y)
t.add_costume("images/alien1.png")
t.border = 1
return t

t0 = create_token(0,0)
t1 = create_token(50,0)
t1.height = 400
t2 = create_token(300,0)
t2.width = 180

board.run()
Textured image

Hides a token (the token will be invisible)

property image: pygame.Surface

The image of the token:

Warning

Warning: You should not directly draw on the image as the image will be reloaded during animations

Return type:

Surface

property is_filled

Is token filled with color?

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)
token = Token()
token.add_costume("images/alien1.png")
token.height= 400
token.width = 100
token.is_rotatable = False
@token.register
def act(self):
    if self.board.frame % 100 == 0:
        if self.is_flipped:
            self.is_flipped = False
        else:
            self.is_flipped = True
board.run()

Output:

Returns:

True, if token is flipped

Return type:

bool

property is_rotatable: bool

Defines if the costume of a token should be rotatable. The token can still be rotated with the direction property, but its costume won’t be changed

Note

You can also use token.costume.is_rotatable

Examples

Create a rotatable and a not rotatable token

from miniworldmaker import *
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
