#Trails

A trail is a Trail instance welded between SAE_TrailTop and SAE_TrailBottom attachments on the character's HumanoidRootPart, with Lifetime = 0.6, a tapering width and 0.4 light emission. It is purely visual — the gameplay effect is the multiplier it applies to treadmill Speed.

TrailService.buy grants the trail, equips it and applies the visual immediately; equip and unequip switch without spending. The currency is cash only — the Robux column above matches the intended Config.TrailProducts product prices, but every entry in that table is still 0, so the Robux path is not wired up yet.

#Shop structure

Config.Shop describes the in-game shop panel:

Section	Contents
`passes`	`DoubleGrowth`, `DoubleMoney`, `ExtraSlots`
`speed`	Six one-off Speed packages
`cash`	Six one-off cash packages

Config.ExclusiveShop is the separate premium panel and re-uses the same keys in three sections (passes, speed, money) with a kind of pass or product.

#Game passes

Pass	Effect	Price shown in `Config.Shop`
`DoubleGrowth`	`growthMul = 2`	467 Robux
`DoubleMoney`	`incomeMul = 2`	399 Robux
`ExtraSlots`	`+4` pet slots	249 Robux

#Developer products

Product	Grant	Price shown
`Speed150K`	+150,000 Speed	79 Robux
`Speed1M`	+1,000,000 Speed	249 Robux
`Speed10M`	+10,000,000 Speed	699 Robux
`Speed50M`	+50,000,000 Speed	1,299 Robux
`Speed500M`	+500,000,000 Speed	2,499 Robux

`Cash8M`	$8,000,000	1,299 Robux

#Before you enable purchases

Every entry in Config.Monetization.GamePasses and Config.Monetization.DeveloperProducts still has id = 0. MonetizationService.isConfigured() walks both lists and returns false while they are all zero, which disables the whole purchase flow — prompts do nothing and processReceipt is never reached with a real purchase.

To go live:

Create the passes and products on the experience.
Paste the numeric IDs into Config.Monetization.
Align the display prices in Config.Shop with the real ones. The two tables currently disagree: Config.Shop shows DoubleGrowth at 467 and DoubleMoney at 399, while Config.Monetization lists both at 335 and gives ExtraSlots no price at all.
Fill Config.TrailProducts if trails should be purchasable with Robux.
Fill Features.Badges (six IDs, all 0) if badges should award.

#Cash economy

Setting	Value
`Config.Economy.SELL_INCOME_SECONDS`	90 — reference for pet sale value
`Config.Economy.GROW_ALL_PRICE_PER_SECOND`	2 cash per remaining second
`Config.Economy.GROW_ALL_FREE_COOLDOWN`	600 s
`Config.Economy.SAVE_INTERVAL`	60 s

EconomyService.sane guards every gain and spend re-checks affordability, so a bad or oversized value is rejected rather than written to the profile.
