Index Screen

In short

INDEX on the title screen’s top bar opens a full-screen list of everything in the game and what’s coming. It is rebuilt from the ContentDatabase every time it opens, so new content shows up with no index work. Only things that are not built yet are written by hand, as “coming soon” lines in IndexCatalog.AddPlanned.

How it works

1. The top bar (LobbyNav) has PLAY, CUSTOMIZE, PERKS, BATTING CAGE and INDEX. INDEX calls GameRoot.EnterIndex (state GameState.Index). The top bar stays up with INDEX raised; PERKS and BATTING CAGE still open their popups over it.
2. On opening, IndexView.Open calls IndexCatalog.Build(content) and starts on the first tab, first sub tab, first entry. Nothing is remembered between visits.
3. Tabs (one per IndexCategory, in this order): BATTERS, PITCHERS, BALLPARKS, EQUIPMENT, FOOD, SPECIAL BALLS. Pitchers and Equipment get a second row of sub tabs.
4. Left: the tab’s entries as cards, two per row, scrolling when needed. Each card shows a coloured circle, the name and a subtitle. Right: the picked entry’s name, subtitle, description and bullet details.
5. A “coming soon” entry has a ”?” in a grey circle, the subtitle COMING SOON and a purple COMING SOON pill. A tab with no entries at all (Food today) shows COMING SOON and “Food will be listed here as they’re added.”
6. Esc (or PLAY on the top bar) goes back to the title screen. Esc first closes an open popup.

Where each tab gets its data (IndexCatalog.Build):

Tab	Source	Sub tabs	Subtitle	Details
Batters	db.batters	none	Starter, “Account level n”, or Unlockable	The batter’s stat modifiers
Pitchers	db.pitchers	Pitchers, Bosses (isBoss)	The pitch names in their mix	”Throws: …”, batter modifiers, their own special balls and decoys (DescribeBalls)
Ballparks	db.practiceParks first (subtitle “Batting cage”), then db.ballparks	none	”Batting cage” or blank	The park’s modifiers (DescribeModifiers), “n targets past the wall”
Equipment	db.upgrades, Common then Rare then Epic	Bats, Cleats, Gloves, Charms (by slot)	The rarity	Stat modifiers, “Tags: …”
Food	nothing yet	none
Special Balls	every BallEffect value except None	none	The parks and pitchers that throw it, or “Special ball”	Description from IndexCatalog.BallDescription

Planned entries today (AddPlanned): Special Balls Heavy, Ice, Fire. Food has only a commented example (hot_dog).

Adding an entry:

• Real content: add it to the ContentDatabase (see Add a Pitcher or Boss, Add an Upgrade, Add a Map, Add a Batter, Add a Special Ball). It is listed automatically.
• A planned item: add Planned(entries, IndexCategory.X, "id", "Name", "What it does.", colour) in AddPlanned. Delete the line once the real thing exists, or it shows twice.
• A new special ball kind: give it a line in BallDescription, or it reads “A special ball.”
• A new tab: add an IndexCategory value (and its sub tabs in SubTabs if it needs them). IndexView needs no change.

Numbers

What	Value	Where to tune
Columns of cards	2	IndexView.Columns
Card height / gap	74 / 10 px	IndexView.CardH, CardGap
List width	58% of the panel	IndexView.Draw
Rarity colours	Common grey, Rare blue, Epic purple	IndexCatalog.RarityColor

Gotchas

• The index lists everything, locked or not: it is a catalogue, not a progress tracker. It shows no prices, levels you own, or what you have unlocked.
• Equipment means shop upgrades, not cosmetics; cosmetics are not listed (see Customization).
• Ballpark card colour is just day (green) or night (blue), from isNight.
• Pitchers’ arsenal subtitle can be long; it is shrunk to fit (FitText).
• README.md documents the same “add an index entry” rule in its How to add things table.
