Binary Space Partitioning tcod.bsp
#
Libtcod’s Binary Space Partitioning.
The following example shows how to traverse the BSP tree using Python. This assumes create_room and connect_rooms will be replaced by custom code.
Example:
import tcod.bsp
bsp = tcod.bsp.BSP(x=0, y=0, width=80, height=60)
bsp.split_recursive(
depth=5,
min_width=3,
min_height=3,
max_horizontal_ratio=1.5,
max_vertical_ratio=1.5,
)
# In pre order, leaf nodes are visited before the nodes that connect them.
for node in bsp.pre_order():
if node.children:
node1, node2 = node.children
print('Connect the rooms:\n%s\n%s' % (node1, node2))
else:
print('Dig a room for %s.' % node)
- class tcod.bsp.BSP(x: int, y: int, width: int, height: int)[source]#
A binary space partitioning tree which can be used for simple dungeon generation.
- children#
A tuple of (left, right) BSP instances, or an empty tuple if this BSP has no children.
- Parameters:
- find_node(x: int, y: int) BSP | None [source]#
Return the deepest node which contains these coordinates.
- Returns:
BSP object or None.
- inverted_level_order() Iterator[BSP] [source]#
Iterate over this BSP’s hierarchy in inverse level order.
New in version 8.3.
- level_order() Iterator[BSP] [source]#
Iterate over this BSP’s hierarchy in level order.
New in version 8.3.
- post_order() Iterator[BSP] [source]#
Iterate over this BSP’s hierarchy in post order.
New in version 8.3.
- pre_order() Iterator[BSP] [source]#
Iterate over this BSP’s hierarchy in pre order.
New in version 8.3.
- split_once(horizontal: bool, position: int) None [source]#
Split this partition into 2 sub-partitions.
- split_recursive(depth: int, min_width: int, min_height: int, max_horizontal_ratio: float, max_vertical_ratio: float, seed: Random | None = None) None [source]#
Divide this partition recursively.
- Parameters:
depth (int) – The maximum depth to divide this object recursively.
min_width (int) – The minimum width of any individual partition.
min_height (int) – The minimum height of any individual partition.
max_horizontal_ratio (float) – Prevent creating a horizontal ratio more extreme than this.
max_vertical_ratio (float) – Prevent creating a vertical ratio more extreme than this.
seed (Optional[tcod.random.Random]) – The random number generator to use.
