evennia.contrib.tutorials.evadventure.npcs

EvAdventure NPCs. This includes both friends and enemies, only separated by their AI.

class evennia.contrib.tutorials.evadventure.npcs.EvAdventureNPC(*args, **kwargs)

Bases: evennia.contrib.tutorials.evadventure.characters.LivingMixin, evennia.objects.objects.DefaultCharacter

This is the base class for all non-player entities, including monsters. These generally don’t advance in level but uses a simplified, abstract measure of how dangerous or competent they are - the ‘hit dice’ (HD).

HD indicates how much health they have and how hard they hit. In _Knave_, HD also defaults to being the bonus for all abilities. HP is 4 x Hit die (this can then be customized per-entity of course).

Morale is set explicitly per-NPC, usually between 7 and 9.

Monsters don’t use equipment in the way PCs do, instead they have a fixed armor value, and their Abilities are dynamically generated from the HD (hit_dice).

If wanting monsters or NPCs that can level and work the same as PCs, base them off the EvAdventureCharacter class instead.

The weapon of the npc is stored as an Attribute instead of implementing a full inventory/equipment system. This means that the normal inventory can be used for non-combat purposes (or for loot to get when killing an enemy).

class evennia.contrib.tutorials.evadventure.npcs.EvAdventureTalkativeNPC(*args, **kwargs)

Bases: evennia.contrib.tutorials.evadventure.npcs.EvAdventureNPC

Talkative NPCs can be addressed by talk [to] <npc>. This opens a chat menu with communication options. The menu is created with the npc and we override the .create to allow passing in the menu nodes.

menudata

menu_kwargs

AttributeProperty.

at_damage(damage, attacker=None)

Talkative NPCs are generally immortal (we don’t deduct HP here by default).”

classmethod create(key, account=None, **kwargs)

Overriding the creation of the NPC, allowing some extra **kwargs.

Parameters

• key (str) – Name of the new object.

• account (Account, optional) – Account to attribute this object to.

Keyword Arguments

• description (str) – Brief description for this object (same as default Evennia)

• ip (str) – IP address of creator (for object auditing) (same as default Evennia).

• menudata (dict or str) – The menudata argument to EvMenu. This is either a dict of {“nodename”: <node_callable>,…} or the python-path to a module containing such nodes (see EvMenu docs). This will be used to generate the chat menu chat menu for the character that talks to the NPC (which means the at_talk hook is called (by our custom talk command).

• menu_kwargs (dict) – This will be passed as **kwargs into EvMenu when it is created. Make sure this dict can be pickled to an Attribute.

Returns

tuple – (new_character, errors). On error, the new_character is None and errors is a list of error strings (an empty list otherwise).

at_talk(talker, startnode='node_start', session=None, **kwargs)

Called by the talk command when another entity addresses us.

Parameters

• talker (Object) – The one talking to us.

• startnode (str, optional) – Allows to start in a different location in the menu tree. The given node must exist in the tree.

• session (Session, optional) – The talker’s current session, allows for routing correctly in multi-session modes.

• **kwargs – This will be passed into the EvMenu creation and appended and menu_kwargs given to the NPC at creation.

Notes

We pass npc=self into the EvMenu for easy back-reference. This will appear in the **kwargs of the start node.
