vec2ScaleToLength

vec2ScaleToLength(v, length): Vec2

Defined in: src/modules/math/vec2.ts:22

v rescaled so its length equals length, direction preserved — the canonical “normalize then multiply” for driving a body at a fixed speed from an arbitrary direction (input axis, steering delta, reflected velocity). A zero-length input returns { x: 0, y: 0 }. Sibling of vec3ScaleToLength.

Parameters

v

Vec2

length

number

Returns
