Accessors

angle

Get Signature

get angle(): number;

Defined in: packages/core/src/joints/presets.ts:53

How far it has turned from where it was made, in radians.

Returns

number

---

bodies

Get Signature

get bodies(): readonly Body[];

Defined in: packages/core/src/joints/BaseJoint.ts:59

The bodies the joint ties together.

Returns

readonly Body[]

Inherited from

SixDofJoint.bodies

---

collideConnected

Get Signature

get collideConnected(): boolean;

Defined in: packages/core/src/joints/BaseJoint.ts:26

Whether the two bodies collide with each other; fixed once the joint is in a world.

Returns

boolean

Inherited from

SixDofJoint.collideConnected

---

isOverloaded

Get Signature

get isOverloaded(): boolean;

Defined in: packages/core/src/joints/BaseJoint.ts:64

Whether the loads of the last step are more than the joint can take.

Returns

boolean

Inherited from

SixDofJoint.isOverloaded

---

limits

Get Signature

get limits(): JointLimits | undefined;

Defined in: packages/core/src/joints/presets.ts:36

Returns

JointLimits | undefined

Set Signature

set limits(limits): void;

Defined in: packages/core/src/joints/presets.ts:40

Parameters

Parameter	Type
limits	JointLimits | undefined

Returns

void

---

motor

Get Signature

Defined in: packages/core/src/joints/presets.ts:48

Parameters

Parameter	Type
motor	JointDrive | undefined

Returns

---

roles

Get Signature

get roles(): object;

Defined in: packages/core/src/joints/SixDofJoint.ts:153

The joint's base frame and the frame that moves against it: frame A on body A and frame B on body B; or, for a joint to the world, the world's frame (frameB) and body A's (frameA), so that either way what is measured is how the second body moves.

Returns

object

Name	Type	Defined in
base	JointFrame	packages/core/src/joints/SixDofJoint.ts:153
baseBody	Body | undefined	packages/core/src/joints/SixDofJoint.ts:153

Inherited from

SixDofJoint.roles

Methods

measure()

measure(): JointMeasurement;

Defined in: packages/core/src/joints/SixDofJoint.ts:160

Where the moving frame is relative to the base frame (see roles), as the bodies are now.

Returns

JointMeasurement
