Ideas related to figuring out who the local player is for multiplayer Main or Battle Stages #15

The problem isn't acquiring the player's username, it's that when you're in a Main Stage game with multiple players, the line Ironically this actually is not an issue in Battle Stage at all, it's only in Main Stage when there is more than one player. Feel free to take a look yourself though, maybe I'm missing something. |

I see what you're saying, I've been looking at logs a lot this morning. It's wild how piecemeal the logging seems to be in certain places, like with the game evaluator and how it only logs forgiven swings |

I've had a small breakthrough with this. The log writes two sets of lines that could be cross-referenced to help us determine the line of the local player. To demonstrate, here are two logs. The first is me in a single player Main Stage session. Clearly, I am In this case, we can determine that I am So I tried making a little test script to identify the player by the omission in This time it DOES print me in I ended up writing a little diagnostic script but it doesn't work as I had intended just yet, but may serve as a good starting point for anyone wanting to help me investigate. I'll include that below:
import re
import os
import time
def identify_local_player(log_file_path):
init_pattern = re.compile(r'LogPilgrimGemBreakListener: UPilgrimGemBreakListener::Init: Setup for (FortPlayerStateAthena_\d+) using track (EPilgrimTrackType::Track\w+) and Difficulty (EPilgrimSongDifficulty::Difficulty\w+)')
gem_break_pattern = re.compile(r'LogPilgrimGemBreakListener: Broadcasting GemBreakStart for (FortPlayerStateAthena_\d+)\. Local\((\d)\)')
player_info = {}
gem_break_ids = set()
local_player_id = None
local_player_identified = False
with open(log_file_path, 'r', encoding='utf-8-sig') as log_file:
log_file.seek(0, os.SEEK_END)
while True:
line = log_file.readline()
if not line:
time.sleep(0.1)
continue
init_match = init_pattern.search(line)
if init_match:
player_id, track, difficulty = init_match.groups()
player_info[player_id] = {'track': track, 'difficulty': difficulty}
local_player_identified = False
gem_break_match = gem_break_pattern.search(line)
if gem_break_match:
player_id, is_local = gem_break_match.groups()
gem_break_ids.add(player_id)
if is_local == '1':
local_player_id = player_id
if not local_player_identified:
if local_player_id is None:
# Determine the local player by finding the missing identifier
all_player_ids = set(player_info.keys())
missing_ids = all_player_ids - gem_break_ids
if len(missing_ids) == 1:
local_player_id = missing_ids.pop()
if local_player_id and local_player_id in player_info:
local_player_info = player_info[local_player_id]
session_type = "Single Player" if len(player_info) == 1 else "Multiplayer"
print(f"Local player ID: {local_player_id}")
print(f"Instrument: {local_player_info['track']}")
print(f"Difficulty: {local_player_info['difficulty']}")
print(f"Session Type: {session_type}")
print("-" * 40) # Separator line
local_player_identified = True
if local_player_identified and len(player_info) > len(gem_break_ids):
player_info.clear()
gem_break_ids.clear()
local_player_id = None
local_player_identified = False
if __name__ == "__main__":
log_file_path = os.path.expandvars(r'%localappdata%\FortniteGame\Saved\Logs\FortniteGame.log')
identify_local_player(log_file_path) |
I see the "LogPilgrimCorePlayerState: CLIENT: player LocalAitch set readiness to 1" lines that seem to display for each Battle Stage. The readme states you have not been able to reliably determine who the local player is. If the script is running before the player logs in to Fortnite, there is a line present when the player logs in "[2024.10.14-16.06.47:019][626]LogOnlineAccount: Display: [UOnlineAccountCommon::ProcessUserLogin] Successfully logged in user. UserId=[xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx] DisplayName=[LocalAitch] EpicAccountId=[MCP:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx] AuthTicket=[]" where the strings of x's are 32-byte hex strings that for me were identical. You could parse this line and extract the display name. Not sure what contingency you might want to have if someone runs the script after logging in to Fortnite (or in the slim chance they encounter an issue and have to restart it).
