A deformable 3D physics mesh.
A deformable 3D physics mesh. Used to create elastic or deformable objects such as cloth, rubber, or other flexible materials. Additionally, [SoftBody3D] is subject to wind forces defined in [Area3D] (see [member Area3D.wind_source_path], [member Area3D.wind_force_magnitude], and [member Area3D.wind_attenuation_factor]). [b]Note:[/b] It's recommended to use Jolt Physics when using [SoftBody3D] instead of the default GodotPhysics3D, as Jolt Physics' soft body implementation is faster and more reliable. You can switch the physics engine using the [member ProjectSettings.physics/3d/physics_engine] project setting.

Adds a body to the list of bodies that this body can't collide with.
Distributes and applies a force to all points. A force is time dependent and meant to be applied every physics update.
Distributes and applies an impulse to all points. An impulse is time-independent! Applying an impulse every frame would result in a framerate-dependent force. For this reason, it should only be used when simulating one-time impacts (use the "_force" functions otherwise).

Returns an array of nodes that were added as collision exceptions for this body.
Returns whether or not the specified layer of the [member collision_layer] is enabled, given a [param layer_number] between 1 and 32.
Returns whether or not the specified layer of the [member collision_mask] is enabled, given a [param layer_number] between 1 and 32.
Returns the internal [RID] used by the [PhysicsServer3D] for this body.
Returns local translation of a vertex in the surface array.
Returns [code]true[/code] if vertex is set to pinned.
Removes a body from the list of bodies that this body can't collide with.
Based on [param value], enables or disables the specified layer in the [member collision_layer], given a [param layer_number] between 1 and 32.
Based on [param value], enables or disables the specified layer in the [member collision_mask], given a [param layer_number] between 1 and 32.
Sets the pinned state of a surface vertex. When set to [code]true[/code], the optional [param attachment_path] can define a [Node3D] the pinned vertex will be attached to.
- The physics layers this SoftBody3D [b]is in[/b]. Collision objects can exist in one or more of 32 different layers. See also [member collision_mask]. [b]Note:[/b] Object A can detect a contact with object B only if object B is in any of the layers that object A scans. See [url=$DOCS_URL/tutorials/physics/physics_introduction.html#collision-layers-and-masks]Collision layers and masks[/url] in the documentation for more information.
- The physics layers this SoftBody3D [b]scans[/b]. Collision objects can scan one or more of 32 different layers. See also [member collision_layer]. [b]Note:[/b] Object A can detect a contact with object B only if object B is in any of the layers that object A scans. See [url=$DOCS_URL/tutorials/physics/physics_introduction.html#collision-layers-and-masks]Collision layers and masks[/url] in the documentation for more information.
- The body's damping coefficient. Higher values will slow down the body more noticeably when forces are applied.
- Defines the behavior in physics when [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED].
- The body's drag coefficient. Higher values increase this body's air resistance. [b]Note:[/b] This value is currently unused by Godot's default physics implementation.
- Higher values will result in a stiffer body, while lower values will increase the body's ability to bend. The value can be between [code]0.0[/code] and [code]1.0[/code] (inclusive).
- [NodePath] to a [CollisionObject3D] this SoftBody3D should avoid clipping.
- The pressure coefficient of this soft body. Simulate pressure build-up from inside this body. Higher values increase the strength of this effect.
- If [code]true[/code], the [SoftBody3D] will respond to [RayCast3D]s.
- Scales the rest lengths of [SoftBody3D]'s edge constraints. Positive values shrink the mesh, while negative values expand it. For example, a value of [code]0.1[/code] shortens the edges of the mesh by 10%, while [code]-0.1[/code] expands the edges by 10%. [b]Note:[/b] [member shrinking_factor] is best used on surface meshes with pinned points.
- Increasing this value will improve the resulting simulation, but can affect performance. Use with care.
- The SoftBody3D's mass.
When [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED], remove from the physics simulation to stop all physics interactions with this [SoftBody3D]. Automatically re-added to the physics simulation when the [Node] is processed again.
When [member Node.process_mode] is set to [constant Node.PROCESS_MODE_DISABLED], do not affect the physics simulation.
