`MotionStageApi.join`

method

Joins two motes' bodies.

Syntax

join(    a: string | Mote,    b: string | Mote,    joint?: MotionJointSpec): number

Name	Type	Description
`a`	`string \| Mote`	One mote (or its id)
`b`	`string \| Mote`	The other
`joint`	`MotionJointSpec`	Optional. How: its kind, anchors, axis, length, stiffness and damping

number: its number, for unjoin (0 when one of them isn't there).

Two bodies in different worlds, or without bodies, aren't joined: the console says why. A joint goes with either body. 1024 joints at most.

import { stage } from "motion";const rope = stage.join("Lantern", "Hook", { kind: "rope", length: 120 });
