Dungeon system

This creates a procedurally generated dungeon.

The dungone originates in an entrance room with exits that spawn a new dungeon connection every X minutes. As long as characters go through the same exit within that time, they will all end up in the same dungeon ‘branch’, otherwise they will go into separate, un-connected dungeon ‘branches’. They can always go back to the start room, but this will become a one-way exit back.

When moving through the dungeon, a new room is not generated until characters decided to go in that direction. Each room is tagged with the specific ‘instance’ id of that particular branch of dungon. When no characters remain in the branch, the branch is deleted.

Each room in the dungeon starts with a Tag not_clear; while this is set, all exits out of the room (not the one they came from) is blocked. When whatever problem the room offers has been solved (such as a puzzle or a battle), the tag is removed and the player(s) can choose which exit to leave through.

evennia.contrib.tutorials.evadventure.dungeon.random() → x in the interval [0, 1).

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonRoom(*args, **kwargs)

基类：evennia.contrib.tutorials.evadventure.rooms.EvAdventureRoom

Dangerous dungeon room.

allow_combat

AttributeProperty.

allow_death

AttributeProperty.

dungeon_branch

AttributeProperty.

xy_coords

AttributeProperty.

at_object_creation()

Set the not_clear tag on the room. This is removed when the room is ‘cleared’, whatever that means for each room.

We put this here rather than in the room-creation code so we can override easier (for example we may want an empty room which auto-clears).

clear_room()

property is_room_clear

get_display_footer(looker, **kwargs)

Show if the room is ‘cleared’ or not as part of its description.

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonExit(*args, **kwargs)

基类：evennia.objects.objects.DefaultExit

Dungeon exit. This will not create the target room until it’s traversed.

at_object_creation()

We want to block progressing forward unless the room is clear.

at_traverse(traversing_object, target_location, **kwargs)

Called when traversing. target_location will be pointing back to ourselves if the target was not yet created. It checks the current location to get the dungeon-branch in use.

at_failed_traverse(traversing_object, **kwargs)

Called when failing to traverse.

evennia.contrib.tutorials.evadventure.dungeon.room_generator(dungeon_branch, depth, coords)

Plugin room generator

This default one returns the same empty room.

参数

• dungeon_branch (EvAdventureDungeonBranch) – The current dungeon branch.

• depth (int) – The ‘depth’ of the dungeon (radial distance from start room) this new room will be placed at.

• coords (tuple) – The (x,y) coords that the new room will be created at.

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonBranch(*args, **kwargs)

基类：evennia.scripts.scripts.DefaultScript

One script is created per dungeon ‘branch’ created. The branch is responsible for determining what is created next when a character enters an exit within the dungeon.

max_unexplored_exits = 2

max_new_exits_per_room = 2

AttributeProperty.

unvisited_exits

AttributeProperty.

last_updated

AttributeProperty.

room_generator

AttributeProperty.

xy_grid

AttributeProperty.

start_room

AttributeProperty.

register_exit_traversed(exit)

Tell the system the given exit was traversed. This allows us to track how many unvisited paths we have so as to not have it grow exponentially.

create_out_exit(location, exit_direction='north')

Create outgoing exit from a room. The target room is not yet created.

delete()

Clean up the entire dungeon along with the branch.

new_room(from_exit)

Create a new Dungeon room leading from the provided exit.

参数

from_exit (Exit) – The exit leading to this new room.

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonStartRoomExit(*args, **kwargs)

基类：evennia.objects.objects.DefaultExit

Traversing this exit will either lead to an existing dungeon branch or create a new one.

Since exits need to have a destination, we start out having them loop back to the same location and change this whenever someone actually traverse them. The act of passing through creates a room on the other side.

reset_exit()

Flush the exit, so next traversal creates a new dungeon branch.

at_traverse(traversing_object, target_location, **kwargs)

When traversing create a new branch if one is not already assigned.

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonBranchDeleter(*args, **kwargs)

基类：evennia.scripts.scripts.DefaultScript

Cleanup script. After some time a dungeon branch will ‘collapse’, forcing all players in it back to the start room.

branch_max_life

AttributeProperty.

at_script_creation()

Only called once, when script is first created.

at_repeat()

Go through all dungeon-branchs and find which ones are too old.

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureStartRoomResetter(*args, **kwargs)

基类：evennia.scripts.scripts.DefaultScript

Simple ticker-script. Introduces a chance of the room’s exits cycling every interval.

at_script_creation()

Only called once, when script is first created.

at_repeat()

Called every time the script repeats.

class evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonStartRoom(*args, **kwargs)

基类：evennia.contrib.tutorials.evadventure.dungeon.EvAdventureDungeonRoom

The start room is the only permanent part of the dungeon. Exits leading from this room (except one leading back outside) each create/links to a separate dungeon branch/instance.

• A script will reset each exit every 5 mins; after that time, entering the exit will spawn

  a new branch-instance instead of leading to the one before.

• Another script will check age of branch instance every hour; once an instance has been

  inactive for a week, it will ‘collapse’, forcing everyone inside back to the start room.

The actual exits should be created in the build script.

recycle_time = 300

room_generator

AttributeProperty.

get_display_footer(looker, **kwargs)

Show if the room is ‘cleared’ or not as part of its description.

at_object_creation()

Set the not_clear tag on the room. This is removed when the room is ‘cleared’, whatever that means for each room.

We put this here rather than in the room-creation code so we can override easier (for example we may want an empty room which auto-clears).

at_object_receive(obj, source_location, **kwargs)

Make sure to clean the dungeon branch-tag from characters when leaving a dungeon branch.
