These leaves define the ground of the map.

Fields

`FloorKeyHash`

type UIntArray hash 0x78e32e1c Documented

Per-cell terrain map of the player’s island, stored as a flat row-major UInt32 array of GridX × GridZ cells (9600 entries, 120 × 80). Each value is the murmur3_x86_32 hash of a type of floor.

Common floor keys

Hash	`FloorDefine` row
`0xFF4AE68A`	`Grass`
`0xD21B65B6`	`Water`
`0xB6D76A62`	`Beach`
`0xB53F5F3D`	`Seaside`
`0xA27341ED`	`Clover`
`0xCF83CF1F`	`Concrete`
`0x318904D8`	`Concrete_Road`
`0x9999D173`	`Soil`

The full vocabulary is enumerated by romfs/RSDB/FloorDefine.Product.[ver].rstbl.byml. Cells whose key is UGC (0x69FFF2F1) pair with a matching entry in the UgcIndex array, which holds the UGC slot index for that cell, non-UGC cells leave UgcIndex as -1.

In-game	`murmur3_x86_32` of any `FloorDefine` row name (e.g. `Grass`, `Water`, `Asphalt_Road`, `UGC`).
Accepted	any `UInt32`, values that aren’t in `FloorDefine` fallback to `Soil` in game.

`UgcIndex`

type IntArray hash 0x6b552914 Documented

Companion to FloorKeyHash: same shape (flat row-major Int32, 9600 entries for GridX × GridZ), one slot per island cell. Whenever a cell’s FloorKeyHash is UGC (0x69FFF2F1), UgcIndex holds the index of the Ugc/UgcMapFloor%03d.{canvas,ugctex}.zs slot to use. Every other cell have the value -1.

In-game	`-1` for cells with no UGC floor, otherwise `0`..`99`, matching the UGC index.
Accepted	any signed `Int32`. If there is no match, it will fallback to `Soil` in game.
