Struct PhysicsVelocity

The velocity of a rigid body. If absent, the rigid body is static.

Namespace: Unity.Physics
Syntax
public struct PhysicsVelocity : IComponentData

Fields

Angular

The body's angular velocity in radians per second about each principal axis specified by Transform. In order to get or set world-space values, use and , respectively.

Declaration
public float3 Angular
Field Value
Type Description
Unity.Mathematics.float3

Linear

The body's world-space linear velocity in units per second.

Declaration
public float3 Linear
Field Value
Type Description
Unity.Mathematics.float3

Methods

CalculateVelocityToTarget(PhysicsMass, Translation, Rotation, RigidTransform, Single)

Create a PhysicsVelocity required to move a body to a target position and orientation. Use this method to control kinematic bodies directly if they need to generate contact events when moving to their new positions. If you need to teleport kinematic bodies you can simply set their Translation and Rotation values directly.

Declaration
public static PhysicsVelocity CalculateVelocityToTarget(in PhysicsMass bodyMass, in Translation bodyPosition, in Rotation bodyOrientation, in RigidTransform targetTransform, in float stepFrequency)
Parameters
Type Name Description
PhysicsMass bodyMass

The body's PhysicsMass component.
Translation bodyPosition

The body's Translation component.
Rotation bodyOrientation

The body's Rotation component.
Unity.Mathematics.RigidTransform targetTransform

The desired Translation and Rotation values the body should move to in world space.
Single stepFrequency

The step frequency in the simulation where the body's motion is solved (i.e., 1 / FixedDeltaTime).
Returns
