Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:193

6-DoF constraint built on a Joint. Defaults to fixed; selectively unlock translation and rotation on X/Y/Z and configure limits and springs.

Properties​

unlockedMotion​

unlockedMotion: UInt32;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:198

Unlock motion along/around the specified axes.

Default Value​

0;

motionLowerLimit​

motionLowerLimit: Vec3;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:203

Lower linear limit per axis (meters).

Default Value​

(0, 0, 0);

motionUpperLimit​

motionUpperLimit: Vec3;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:208

Upper linear limit per axis (meters).

Default Value​

(0, 0, 0);

motionLimitSpringStiffness​

motionLimitSpringStiffness: Vec3;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:213

Linear limit spring stiffness per axis (N/m). >0 makes the limit soft (spring-like).

Default Value​

(0, 0, 0);

motionLimitSpringDamping​

motionLimitSpringDamping: Vec3;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:218

Linear limit spring damping per axis (N·s/m).

Default Value​

(0, 0, 0);

swingLimitAngle​

swingLimitAngle: Vec2;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:223

Swing cone half-angles about Y and Z of the constraint frame (degrees). 0 does not restrict rotation; max 180. Used if either swing axis is limited.

Default Value​

(0, 0);

swingSpringStiffness​

swingSpringStiffness: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:228

Swing limit spring stiffness (N·m/rad). >0 makes the limit soft.

Default Value​

0;

swingSpringDamping​

swingSpringDamping: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:233

Swing limit spring damping (N·m·s/rad).

Default Value​

0;

twistLimitAngle​

twistLimitAngle: Vec2;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:238

Twist angle limits (min,max) around the twist axis (degrees). Range (−360, 360).

Default Value​

(0, 0);

twistSpringStiffness​

twistSpringStiffness: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:243

Twist limit spring stiffness (N·m/rad). >0 makes the limit soft.

Default Value​

0;

twistSpringDamping​

twistSpringDamping: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:248

Twist limit spring damping (N·m·s/rad).

Default Value​

0;
