Diablo II Filter Simulation (Path of Diablo & Project Diablo II)
This program allows users to select an item and see how a filter would display that item, simulating the in-game behavior.
- Compare aesthetics of multiple filters
- Determine whether a filter shows what you're looking for
- Diagnose filter problems
- Discover which rules are responsible for displaying/hiding different items
By default, the simulation updates when any character/item changes are made. For large or complex filters, disable Auto-Simulate and/or Error Checking from the Options menu and use manual simulation instead by clicking the background image.
The background images can be changed by right-clicking them.
URL parameters (v=PD2, alternate=0, multiple=0, auto=0, checking=0) can be used to load the filter with certain menu options enabled/disabled. For example: https://betweenwalls.github.io/filterbird/?v=PD2&multiple=0&auto=0
- Nothing special is done to display item notifications or minimap icons
- All PD2 items use the same attributes as those in the PoD version (with the exception of PD2-specific equipment and pointmod attribute names)
- PD2-specific equipment items and runeword options aren't hidden if the PoD version is selected (and vice versa)
- Unique and set items cannot have their attributes customized
- Crafted items don't have predetermined affixes
- Wirt's Leg and quest weapons cannot be customized
- Item condition issues:
- "CHSK" codes for skill charges and "OS" codes for oskills are unimplemented
- PRICE is not updated automatically
- Unimplemented PoD-specific conditions: AREALVL (may be others due to poor documentation, please report them)
- Unimplemented PD2-specific conditions: PREFIX, SUFFIX, MAPID
- STAT360 (item corruption) is only partially implemented - it checks whether a corruption exists, but not which corruption
- There may be some numbered "STAT" codes which aren't implemented - please report them
- Many PD2 changes after s6 have not been implemented, or have only been partially implemented
If you would like to improve this program, or just share feedback about how it could be improved, you can message me on reddit (BetweenWalls) or discord (@BetweenWalls#2390). You can also just open an issue here.
Potential Improvements:
- Address known issues listed above
- Optimize simulation performance so that major features can be added:
- Allow multiple items to be viewed simultaneously
- Create option to generate variety of different items so filters can be compared effectively with just a few clicks
- Allow any number of filters to be compared simultaneously
- Make item tooltip formatting better match in-game tooltip formatting
- Expand syntax/error checking to further help with diagnosing filter problems
