Function: contains() ​

contains(r, p): boolean

Defined in: ui/src/view/geometry.ts:69

Test whether a point lies inside a rect. Bounds are half-open (x ≤ p.x < x + width, y ≤ p.y < y + height), so two edge-adjacent rects never both contain the same cell — handy for hit-testing tiled regions.

Parameters ​

r ​

Rect

The rect.

p ​

Point

The point to test.

Returns ​

boolean

true when p is inside r.

Example ​

ts
import { contains } from '@jsvision/ui';

const rect = { x: 0, y: 0, width: 4, height: 4 };
contains(rect, { x: 3, y: 3 }); // true
contains(rect, { x: 4, y: 0 }); // false — right edge is exclusive
