Interfaces

ISwipeVec2

2D vector in swipe coordinate space.

interface ISwipeVec2 {
  x: number;
  y: number;
}

ISwipeVec3

2D vector with rotation (angle in degrees).

interface ISwipeVec3 extends ISwipeVec2 {
  angle: number;
}

ISwipeState

Pointer sample: position plus time (ms, performance.now()).

interface ISwipeState extends ISwipeVec3 {
  time: number;
}

ISwipeMatrix

Deprecated

Use ISwipeVec3 or ISwipeState instead.

interface ISwipeMatrix extends ISwipeVec3 {}

ISwipeAxes

Optional numeric values per axis (x, y, angle).

• bounds: each array is normalized to [min, max] movement limits.
• snap: each array lists snap targets in movement space.

interface ISwipeAxes {
  x?: number[];
  y?: number[];
  angle?: number[];
}

ISwipeCoords

Snapshot on swipe callbacks and accessors.

Pointer space: start, prev, current, diff, step, accum.
Movement space: movement, prevMovement, scale (after rubber and snap — use for transforms with bounds).

interface ISwipeCoords {
  /** Last event timestamp (ms). */
  timestamp: number;
  /** Pointer position at swipe start. */
  start: ISwipeState;
  /** Previous pointer position. */
  prev: ISwipeState;
  /** Current pointer position. */
  current: ISwipeState;
  /** Offset from `start` to `current` (angle is accumulated). */
  diff: ISwipeState;
  /** Offset from `prev` to `current`. */
  step: ISwipeState;
  /** Absolute path length since swipe start (`|step|` per axis). */
  accum: ISwipeVec3;
  /** Total displacement in movement space (rubber + snap applied). */
  movement: ISwipeVec3;
  /** Movement on the previous frame (movement space, after rubber and snap). */
  prevMovement: ISwipeVec3;
  /** Current scale modifier (default `1`). */
  scale: number;
}

ISwipeCanMoveArg

Arguments for willAbort.

interface ISwipeCanMoveArg {
  type: 'touch' | 'mouse';
  /** Current pointer sample. */
  state: ISwipeState;
  /** Pointer position when the gesture began. */
  start: ISwipeVec2;
  /** Offset from `start` to `state` (pointer space). */
  diff: ISwipeVec2;
}
