Installation

pip install arkparser
# or editable install for development
pip install -e .

Quick Start

Player Profile

from arkparser import Profile

profile = Profile.load("path/to/player.arkprofile")  # auto-detects ASE/ASA

print(profile.player_name)         # Platform gamertag / display name
print(profile.character_name)      # In-game character name
print(profile.level)               # 105
print(profile.tribe_id)            # 1729028872
print(profile.engram_blueprints)   # ["EngramEntry_Campfire_C", ...]
print(profile.get_stat(0))         # Health level-up points
print(profile.to_dict())           # Full dict export

Tribe Data

from arkparser import Tribe

tribe = Tribe.load("path/to/tribe.arktribe")

print(tribe.name)           # "My Tribe"
print(tribe.tribe_id)       # 1729028872
print(tribe.member_count)   # 3
for member in tribe.get_members():
    print(f"  {member['name']} (ID: {member['id']})")
print(tribe.log_entries)    # ["Day 45: Tamed a Rex", ...]

Cloud Inventory / Obelisk

from arkparser import CloudInventory

inv = CloudInventory.load("path/to/obelisk_file")  # or use Obelisk alias

print(f"Creatures: {inv.creature_count}")
print(f"Items: {inv.item_count}")

for creature in inv.uploaded_creatures:
    print(f"  {creature.species} Lv{creature.level} - {creature.name}")
    print(f"  Stats: {creature.stats.to_dict()}")

for item in inv.uploaded_items:
    print(f"  {item.display_name} x{item.quantity} ({item.quality_name})")
    if item.is_cryopod and item.cryopod_creature:
        cryo = item.cryopod_creature
        print(f"    Contains: {cryo.species} Lv{cryo.level}")

World Save

from arkparser import WorldSave

# Works with both ASE (binary) and ASA (SQLite); auto-detected
save = WorldSave.load("path/to/Extinction.ark")       # ASE
save = WorldSave.load("path/to/Extinction_WP.ark")    # ASA

print(f"Objects: {save.object_count}")
print(f"Creatures: {len(save.get_creatures())}")
print(f"Structures: {len(save.get_structures())}")
print(f"Parse errors: {save.parse_error_count}")
print(f"Is ASA: {save.is_asa}")

World Save Models

Extract typed models from parsed world saves:

from arkparser.models import TamedCreature, WildCreature, Player, Structure

# From game objects in a world save
for obj in save.objects:
    class_name = obj.class_name or ""
    if "DinoCharacterStatusComponent" not in class_name:
        tamed = TamedCreature.from_game_object(obj, status_component)
        print(f"{tamed.name} Lv{tamed.level}")

JSON Export

from arkparser import export_all
from arkparser.common import get_map_config

map_config = get_map_config("extinction.ark")
data = export_all(save, map_config)
# Returns: {"tamed": [...], "wild": [...], "players": [...], ...}

Or export to files:

from arkparser import export_to_files

export_to_files(save, "output/", map_config)
# Creates: tamed.json, wild.json, players.json, etc.

For compatibility with the original ASV (Ark Save Visualizer) export naming:

from arkparser import export_all, export_to_files

data = export_all(save, map_config, naming="asv")
# Returns: {"ASV_Tamed": [...], "ASV_Wild": [...], "ASV_Players": [...], ...}

export_to_files(save, "output/", map_config, naming="asv")
# Creates: ASV_Tamed.json, ASV_Wild.json, ASV_Players.json, etc.

Credits

This library was built by reverse-engineering ARK save formats with heavy reference to ASV (Ark Save Visualizer) by miragedmuk. The C# implementation in ASV served as the primary reference for porting the binary parsing logic to Python.
