What are tokens?#
A Token is a token on your board.
All objects on your board are tokens, which can be moved around the board and can communicate with each other.
Example: Create a token#
After you have created the board, a token (i.e. a character) is placed on the board. character)* is placed on the board. This goes like this:
1from miniworldmaker import * 2board = TiledBoard() 3board.columns = 20 4board.rows = 8 5board.tile_size = 42 6board.add_background("images/soccer_green.jpg") 7player = Token() 8 9board.run()
What happens here?
In line 7 a
player object is created. The token is added in the upper left corner.
Initially, the token is displayed as a purple rectangle because it has no color or background.
Every ‘token’ has a ‘costume’. To make your tokens look different, you can put a costume on your token. costume to your token.
Add a new costume#
You can add a new costume with the following command.
path_to_image is a (relative path) to the image.
You should put your images in the subfolder
images. To the image
my_image.png in the subfolder
images you can access with the path
We add a costume in the example from above:
from miniworldmaker import * board = TiledBoard() board.columns = 20 board.rows = 8 board.tile_size = 42 board.add_background("images/soccer_green.jpg") board.speed = 30 player = Token() player.add_costume("images/player.png") board.run()
Example: Multiple costumes#
Here four tokens are created that all have different costumes:
import miniworldmaker board = miniworldmaker.TiledBoard() board.columns = 5 board.rows = 4 board.add_background("images/soccer_green.jpg") t1 = miniworldmaker.Token((0,1)) t1.add_costume("images/cow.png") t2 = miniworldmaker.Token((1,1)) t2.add_costume("images/chicken.png") t3 = miniworldmaker.Token((2,1)) t3.add_costume("images/dog.png") t4 = miniworldmaker.Token((3,1)) t4.add_costume("images/goat.png") board.run()
FAQ about costumes#
My token is misaligned, what should I do?
A token is correctly aligned when the image is facing upwards. faces upwards. If the image is aligned in another direction by default then you have two possibilities
You can rotate the image with an image editor.
You can change the orientation of the costume in Miniworldmaker. This can be done with
my_token.costume.orientation = 90Set for orientation so that the costume is oriented correctly. oriented.
Sometimes it is also necessary to set, that the token can rotate but the costume can rotate, but the costume should always be oriented the same way. This can be done with
my_token.costume.is_rotatable = False.
The token was created in the upper left corner. If you want to create the token at an arbitrary position, then you have to pass a position when calling it.
The miniworldmaker uses a coordinate system for this, the upper left corner is the position (0,0):
Position on a TiledBoard#
On a TiledBoard, the tiles can be accessed directly with coordinates. The coordinate (2,1) therefore indicates the tile that is reached if you move from the top left 2 tiles to the right and 1 tile down.
Tokens always have the size of a tile.
Position on a PixelBoard#
On a PixelBoard, the
position denotes the x and y coordinates that you can read on the screen. The
position of a token is always the upper left corner of the token.
In the example above you can change the position as follows:
from miniworldmaker import * board = TiledBoard() board.columns = 20 board.rows = 8 board.tile_size = 42 board.add_background("images/soccer_green.jpg") board.speed = 30 player = token() player.add_costume("images/player.png") player.position = (3,4) board.run()
Types of tokens#
There are some special tokens you can use:
There are several shapes, e.g.
Ellipse with which you can draw geometric objects. These objects do not require a costume.
Geometric objects can currently only be drawn on a
PixelBoard, not on a
Drawing a circle using position and radius:
import miniworldmaker board = miniworldmaker.PixelBoard(80, 60) miniworldmaker.Circle((40,30), 20) board.run()
You can use the following geometric objects:
The syntax for drawing a line looks like this:
endpoint are tuples, e.g. (1, 2) for x=1 and y=2.
If you want to draw a line from (10,10) to (100, 200) you have to write e.g. the following:
from miniworldmaker import * board = PixelBoard(800, 600) line((10,10), (100, 200)) board.run()
You can create circles in general as follows:
The position is the center of the circle.
If you want to create a circle at the position (400,300) with radius 20, you have to write the following:
from miniworldmaker import * board = PixelBoard(800, 600) Circle((400,300), 20) board.run()
A rectangle is described by position, width and height:
Rectangle(position, width, height)
position describes the upper left corner of the rectangle.
If you want to draw a rectangle at position (100, 100) with width 20 and height 100, you have to write the following:
code-block:: python from miniworldmaker import * board = PixelBoard(800, 600) Rectangle((100, 100), 20, 100) board.run()
Ellipses are described in the same way as rectangles, i.e. the ellipse is then drawn so that it fits exactly inside the rectangle. Width and height refer to the diameter of the ellipse.
ellipse(position, width, height)
If you want to draw an ellipse at position (100, 100) with width 20 and height 100, you must write the following:
from miniworldmaker import * board = PixelBoard(800, 600) Rectangle((100, 100), 20, 100) board.run()
