Brief Description

Base class for all objects affected by physics in 2D space.

Description

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

Property Descriptions

  • int collision_layer
Setter set_collision_layer(value)
Getter get_collision_layer()

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.

  • int collision_mask
Setter set_collision_mask(value)
Getter get_collision_mask()

The physics layers this area scans for collisions.

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

Method Descriptions

  • void add_collision_exception_with ( Node body )

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

  • Array get_collision_exceptions ( )

Returns an array of nodes that were added as collision exceptions for this body.

  • bool get_collision_layer_bit ( int bit ) const

Returns an individual bit on the collision mask.

  • bool get_collision_mask_bit ( int bit ) const

Returns an individual bit on the collision mask.

  • void remove_collision_exception_with ( Node body )

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

  • void set_collision_layer_bit ( int bit, bool value )

Sets individual bits on the layer mask. Use this if you only need to change one layer’s value.

  • void set_collision_mask_bit ( int bit, bool value )

Sets individual bits on the collision mask. Use this if you only need to change one layer’s value.
