The drop simulator uses item type and quality generating functions and data files from D2 (TreasureClassEx.txt, ItemRatio.txt, ...) to reproduce the game's random loot drop mechanic. Quest bosses and other units like Cows, Countess, Council are available.
- The code is open source and available here
- To play, download the zip here extract and double click
dropsim.exe - Note: Windows will complain that the app is not signed by a verified source the first time it's launched. I click on "Show more" then "Run anyway"
- An online drop simulator can be used here: https://pairofdocs.github.io/d2-dropsim-web/
Each session's drops are logged to a file session.txt
Will RNG drop a Shako? Vipermagi, Gheeds, Occy?
Vampgaze, Duriels, Skullders?
- Enable/disable check for same unique per run
- Ethereal status
Specify the number of runs to simulate with the text input field underneath the button Run x times. The results of the runs will be logged to the file session.txt. Drop sounds are disabled if the number of runs is more than 1.
A button to toggle drop sounds enables/disables playing a sound effect while loot is 'dropped' by a boss/monster.
D2 mp3 files from this reddit thread are included in the sound/ folder.
To use one of these sound files as the app's drop sound, rename the file to dropsound.mp3. To use your own drop sound effect, place your mp3 sound file in sound/ and rename it to dropsound.mp3.
The Seed text input field allows setting a random number generator seed (an integer value) so that drops for a series of runs can be reproduced. The seed can only be set once for the duration of the app. If another seed is wanted the app has to be restarted.
Modding the drop rates can be done through the data files in data-113d/. For example: Meph's drop treasure classes and item probabilities can be edited on line 692 in TreasureClassEx.txt. Once edited, restart dropsim.exe and test. The Phrozen Keep has this great guide for TreasureClassEx.txt.
