DropOffset

Interface: DropOffset

Defined in: cascade/tumbleAlgorithm.ts:33

Property	Type	Description	Defined in
`cell`	`number`	Visible cell in the new grid (start-to-end, 0-indexed).	cascade/tumbleAlgorithm.ts:35
`isNew`	`boolean`	True when this is a fresh symbol entering from off-grid, false for a survivor that was already on the reel. The discriminator every caller should branch on; `originalCell < 0` is only equivalent under forward gravity.	cascade/tumbleAlgorithm.ts:60
`offsetCells`	`number`	Signed cell distance this symbol travels: `cell - originalCell`. Positive moves toward the end edge (forward gravity), negative toward the start edge (reverse gravity). Zero means the symbol stays put and must NOT be animated.	cascade/tumbleAlgorithm.ts:53
`originalCell`	`number`	Where this symbol “came from” expressed as a virtual cell index. Off-grid values name the cell the symbol enters from: under `gravity: 'forward'` new symbols come from negative indices (before cell 0); under `'reverse'` they come from `visibleCells` and up. An index inside `[0, visibleCells)` is a survivor’s OLD cell. Read DropOffset.isNew rather than testing the sign - the sign only discriminates under forward gravity.	cascade/tumbleAlgorithm.ts:46
