StaticBody3D

Inherits: PhysicsBody3D < CollisionObject3D < Node3D < Node < Object

Inherited By: AnimatableBody3D

Physics body for 3D physics which is static or moves only by script (without affecting other bodies on its path). Useful for floors and walls.

Description

Static body for 3D physics.

A static body is a simple body that doesn’t move under physics simulation, i.e. it can’t be moved by external forces or contacts but its transformation can still be updated manually by the user. It is ideal for implementing objects in the environment, such as walls or platforms. In contrast to RigidBody3D, it doesn’t consume any CPU resources as long as they don’t move.

They have extra functionalities to move and affect other bodies:

Static transform change: Static bodies can be moved by animation or script. In this case, they are just teleported and don’t affect other bodies on their path. Use AnimatableBody3D instead of StaticBody3D if you need a moving static body that affects other bodies on its path.

Constant velocity: When constant_linear_velocity or constant_angular_velocity is set, static bodies don’t move themselves but affect touching bodies as if they were moving. This is useful for simulating conveyor belts or conveyor wheels.

Warning: With a non-uniform scale this node will probably not function as expected. Please make sure to keep its scale uniform (i.e. the same on all axes), and change the size(s) of its collision shape(s) instead.

Properties

Property Descriptions

Vector3 constant_angular_velocity = Vector3(0, 0, 0)

• void set_constant_angular_velocity ( Vector3 value )

• Vector3 get_constant_angular_velocity ( )

The body’s constant angular velocity. This does not rotate the body, but affects touching bodies, as if it were rotating.

Vector3 constant_linear_velocity = Vector3(0, 0, 0)

• void set_constant_linear_velocity ( Vector3 value )

• Vector3 get_constant_linear_velocity ( )

The body’s constant linear velocity. This does not move the body, but affects touching bodies, as if it were moving.

PhysicsMaterial physics_material_override

• void set_physics_material_override ( PhysicsMaterial value )

• PhysicsMaterial get_physics_material_override ( )

The physics material override for the body.

If a material is assigned to this property, it will be used instead of any other physics material, such as an inherited one.
