Base class for all objects affected by physics in 2D space.
    public class PhysicsBody2D : CollisionObject2D

PhysicsBody2D is an abstract base class for implementing a physics body. All *Body2D types inherit from it.

Properties

    public int CollisionLayer { get; set; }

The physics layers this area is in.

Collidable objects can exist in any of 32 different layers. These layers work like a tagging system, and are not visual. A collidable can use these layers to select with which objects it can collide, using the collision_mask property.

A contact is detected if object A is in any of the layers that object B scans, or object B is in any layer scanned by object A.

    public int CollisionMask { get; set; }

The physics layers this area can scan for collisions.

    public int Layers { get; set; }

Both collision_layer and collision_mask. Returns collision_layer when accessed. Updates collision_layers and collision_mask when modified.

Methods

    public void AddCollisionExceptionWith(Node body)

Adds a body to the list of bodies that this body can’t collide with.

    public int GetCollisionLayer()

Getter for CollisionLayer

    public bool GetCollisionLayerBit(int bit)

Return an individual bit on the collision mask.

    public int GetCollisionMask()

Getter for CollisionMask

    public bool GetCollisionMaskBit(int bit)

Return an individual bit on the collision mask.

    public void RemoveCollisionExceptionWith(Node body)

Removes a body from the list of bodies that this body can’t collide with.

    public void SetCollisionLayer(int layer)

Setter for CollisionLayer

    public void SetCollisionLayerBit(int bit, bool value)

Set/clear individual bits on the layer mask. This makes getting a body in/out of only one layer easier.

    public void SetCollisionMask(int mask)

Setter for CollisionMask

    public void SetCollisionMaskBit(int bit, bool value)

Set/clear individual bits on the collision mask. This makes selecting the areas scanned easier.
