Add a latest replay URL

I am trying to understand how to make a mod that captures information about units through the replay

Looking at the LUA documentation:
https://supcom.fandom.com/wiki/LUADOC_1.5.3599#User
https://github.com/FAForever/fa/blob/develop/engine/User/UserUnit.lua

does using User.UserUnit make it a UI only mod?

For the dump to file script

if unit is alive (using IsDead)

if it is dump a line to log that contains

GetGameTick
GetArmy
GetUnitId
GetPosition
GetOrientation
GetVelocity
GetMaxHealth
GetHealth
GetShieldRatio
IsIdle
UserUnit

repeat every X seconds.

Could dump some unit types info at a faster rate than others, depending on unit speed, or importance for instance.

Do sim mods have access to any files that are not the game log?
Could just add an identifier start charicter to each line of the game log however.
Data could then be put into a better datasctructure and compressed using other external tools / scripting

Is this much script to write? is anyone here able to do so? @maudlin27

@nooby I’ve no experience with UI mods (only SIM mods), you could try in the FAF modding discord in terms of finding out what is possible: https://discord.com/channels/197033481883222026/832710161847287819
You might need to set your roles to indicate an interest in modding to access the channel

However if it was possible then most likely you’d need to write the code yourself (unless one of the modders was interested in doing the same thing)

I have created the "Unit Logger" mod. It is in the mod vault. It is a UI mod.

EDIT - V2 Released with reduced decimal places and unit masskilled added

Logs information on every unit of of focus army every 10 game ticks, configureable in main.lua
Information logged:
"UL02","GameTick","EntityId","Army","UnitId","FractionComplete","Position.x","Position.y","Position.z","MaxHealth","Health","ShieldRatio","IsIdle","MassKilled"
WARNING: If you have 1500 units and an hour game expect gigabyte size logs.
It works in replays if you select the army of the player you require logging.
It requires UMT / UI Mod Tools / ui-mod-tools-4z0t-v12
Thanks for 4z0t for some of the code that makes this work

This data is not in an eficcient format at all - that can be done after the game has ended.

I need to look at logging all units from all armies at once when observer. i dont know if this is possible with a UI mod.

Example data:
