class miniworlds.worlds.tiled_world.tiled_world.TiledWorld(x=20, y=16, tile_size=40, empty=False)

from typing A TiledWorld is a World where each Actor is placed in one Tile.

With Tiled World, you can realize RPGs and Boardgames.

Each Actor on a TiledWorld can be placed on a Tile, on a Corner between Tiles or on an Edge between Tiles.

Examples

Create Actor on Tile, Corner and Edge:

from miniworlds import *
world = TiledWorld(6, 3)
world.grid = True
last_corner = None

tile = Tile((1,1))
t1 = Actor()
t1.center = tile.position
t1.fill_color = (255,255,255)

corner = Corner((3,1), "nw")
t2 = Actor()
t2.center = corner.position
t2.fill_color = (255,0,0)

edge = Edge((5,1), "w")
t3 = Actor()
t3.center = edge.position
t3.fill_color = (0,0,255)
t3.size = (0.2,1)
t3.direction = edge.angle

world.run()

__init__(x=20, y=16, tile_size=40, empty=False)

Initializes the TiledWorld

Parameters:

• view_x – The number of columns

• view_y – The number of rows

• empty – The world has no tiles, edges, and corners. They must be created manually

add_corner_to_world(position, direction)

add_edge_to_world(position, direction)

add_tile_to_world(position)

borders(value)

Returns the World’s borders, if actor is near a Border.

Return type:

list

clear_tiles()

Removes all tiles, corners and edges from World

Instead of clearing the world, you can add the parameter empty to World to create a new World from scratch.

Examples

Clear and re-create world:

from miniworlds import *
world = HexWorld(8, 8)

@world.register
def on_setup(self):
    self.clear_tiles()
    center = HexTile((4, 4))
    for x in range(self.columns):
        for y in range(self.rows):
            if center.position.distance((x, y)) < 2:
                tile = self.add_tile_to_world((x, y))
                tt = Actor()
                t.center = tile.position


world.run()

Create a new world from scratch

Note

This variant is faster, because Tiles are not created twice

from miniworlds import *
world = HexWorld(8, 8, empty=True)

@world.register
def on_setup(self):
    center = HexTile((4, 4))
    for x in range(self.columns):
        for y in range(self.rows):
            if center.position.distance((x, y)) < 2:
                tile = self.add_tile_to_world((x, y))
                tile.create_actor()


world.run()

property columns: int

Gets the number of horizontal pixels (columns) visible in the world.

detect_actors(position)

Gets all actors which are found at a specific position (in global world coordinates)

Return type:

List[Actor]

Parameters:

position – Position, where actors should be searched.
