Type Alias: PhysicsMaterial

type PhysicsMaterial = {
  staticFriction: Float;
  dynamicFriction: Float;
  restitution: Float;
  contactVelocity: Vec3;
  modifyContact: boolean;
  isTrigger: boolean;
};

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:647

Physical surface properties used for contact: friction, restitution, optional contact modification, and trigger mode.

Properties​

staticFriction​

staticFriction: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:652

Static friction coefficient (typically 0..1). 0 feels like ice; higher resists start of motion. Effective value is averaged with the other surface.

Default Value​

0.5;

dynamicFriction​

dynamicFriction: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:657

Dynamic (kinetic) friction coefficient (typically 0..1). If greater than staticFriction, staticFriction is clamped up to match. Effective value is averaged with the other surface.

Default Value​

0.5;

restitution​

restitution: Float;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:662

Restitution (bounciness) in [0,1]. 0 = no bounce; 1 = perfectly elastic. Effective value is averaged with the other surface.

Default Value​

0;

contactVelocity​

contactVelocity: Vec3;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:667

Applied contact velocity offset when colliding (m/s). Only used if modifyContact is true.

Default Value​

(0, 0, 0);

modifyContact​

modifyContact: boolean;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:672

Enable contact modification (applies contactVelocity on collisions).

Default Value​

false;

isTrigger​

isTrigger: boolean;

Defined in: node_modules/@3dverse/livelink.core/dist/_prebuild/engine_types/components.d.ts:677

Treat associated geometry as a trigger (generates events but no physical response).

Default Value​

false;
