DeltaCalc

DeltaCalc is a client-side utility mod for Cobblemon Delta on Fabric 1.21.1.

It adds an in-battle damage calculator, expanded battle overlays, richer tooltips, team indicators, and optional battle-state export for external analysis tools. The goal is to make battle information easier to read and act on without changing Cobblemon's core mechanics, while supporting the custom Pokemon that the Delta mod adds.

Features

• Live damage calculator panel that updates every turn for both your moves and the opponent's
• Opponent set inference (Item, Ability, EV Spread, moves) drawn from Delta ranked usage stats
• Manual overrides on the calc summary — left-click to cycle through alternatives when you know better than the average, right-click to reset
• Battle info overlays for weather, terrain, side conditions, and boosts
• Team indicators with richer tooltip information
• Improved move and battle log readability
• Optional structured battle-state export for external tools

How DeltaCalc Works

DeltaCalc reads the battle information already available to your client during a Cobblemon Delta battle and turns it into a live snapshot for damage estimation. It tracks the active Pokemon, revealed moves, stat stages, HP state, weather, terrain, side conditions, and the rest of the battle context that affects damage.

For the actual calculations, DeltaCalc uses Cobblemon's species data, move data, typing, and the live battle state to build a best-effort damage model in real time. When something hasn't been revealed yet — such as the opponent's exact EV spread, item, or unrevealed moves — DeltaCalc makes a reasonable inference and tightens it as the battle progresses.

Inferences are drawn from:

• A database of the highest-usage sets from the Cobblemon Delta Ranked Usage Analytics site
• The #custom-pokemon threads in the official Cobblemon Delta Discord (for Delta-original mons)
• The most-used OU Singles sets from Smogon (for vanilla Cobblemon species)

Data Sources

DeltaCalc is based on:

• Battle state visible to the client during combat
• Revealed information from the current battle
• Cobblemon's Pokemon, move, type, and stat data
• Active field effects (weather, terrain, screens, boosts, hazards)
• Smogon OU Singles usage stats
• Ranked Usage Analytics for Cobblemon Delta
• The Cobblemon Delta Discord's custom-Pokemon threads

It does not magically know hidden server-side information. If something has not been revealed yet, the calculator treats it as an estimate rather than a confirmed value.

Similar To Showdex

If you've used Showdex on Pokemon Showdown, the idea is similar: provide live damage calculations and battle context directly in the battle UI so you don't have to tab out to a separate calculator. DeltaCalc brings that same workflow to Cobblemon Delta, adapted to Cobblemon battles and the information available in-game.

Optional Dependencies

• Mod Menu (strongly suggested — gives you a settings UI)
• Cloth Config

Notes

• DeltaCalc is client-side only
• Servers do not need to install it for the UI features to work on your client
• Battle export is optional and can be configured or disabled
