The Simulated property is common to all available Body Types. Use this property to start (enabled) or stop (disabled) a Rigidbody 2D and any attached Collider 2Ds and Joint 2Ds from interacting with the 2D physics simulation. Changing this property is more memory and processor efficient than enabling or disabling individual Collider 2D and Joint 2D components.
When you enable the Simulated property, the following occurs:
When you disable the Simulated property, the following occurs:
You can stop and start individual elements of the 2D physics simulation by enabling and disabling physics related components individually on both Collider 2D and Joint 2D components. However, enabling and disabling individual elements of the physics simulations means internal GameObjects and physics-based components are constantly created and destroyed, which can cost high memory usage and processor power. Therefore, it’s more efficient to disable the physics simulation entirely rather than disabling the individual components.
Note: When you disable a Rigidbody 2D’s Simulated option, any attached Collider 2D is effectively ‘invisible’ and can’t be detected by any physics queries, such as with Physics.Raycast
