The naming of static bodies has raised a lot of questions and discussions, because they are actually movable (not being static). This commit explains that the reason for "static" is that they are immovable from the point of view of the physics engine. This makes it easier to understand why the user can move static bodies manually.

|
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:
|
|
[b]Static transform change:[/b] 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.
|
|
[b]Constant velocity:[/b] When [member constant_linear_velocity] or [member 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.

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

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

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.
