說明
|
|
----
|
|
|
|
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 :ref:`Area3D<class_Area3D>` (see :ref:`Area3D.wind_source_path<class_Area3D_property_wind_source_path>`, :ref:`Area3D.wind_force_magnitude<class_Area3D_property_wind_force_magnitude>`, and :ref:`Area3D.wind_attenuation_factor<class_Area3D_property_wind_attenuation_factor>`).
|
|
|
|
\ **Note:** 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 :ref:`ProjectSettings.physics/3d/physics_engine<class_ProjectSettings_property_physics/3d/physics_engine>` project setting.

|void| **apply_central_impulse**\ (\ impulse\: :ref:`Vector3<class_Vector3>`\ ) :ref:`🔗<class_SoftBody3D_method_apply_central_impulse>`
|
|
|
|
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).
