Abstract base class for 2D game objects affected by physics. [PhysicsBody2D] is an abstract base class for 2D game objects affected by physics. All 2D physics bodies inherit from it. $DOCS_URL/tutorials/physics/physics_introduction.html Adds a body to the list of bodies that this body can't collide with. Returns an array of nodes that were added as collision exceptions for this body. Returns the gravity vector computed from all sources that can affect the body, including all gravity overrides from [Area2D] nodes and the global world gravity. Moves the body along the vector [param motion]. In order to be frame rate independent in [method Node._physics_process] or [method Node._process], [param motion] should be computed using [code]delta[/code]. Returns a [KinematicCollision2D], which contains information about the collision when stopped, or when touching another body along the motion. If [param test_only] is [code]true[/code], the body does not move but the would-be collision information is given. [param safe_margin] is the extra margin used for collision recovery (see [member CharacterBody2D.safe_margin] for more details). If [param recovery_as_collision] is [code]true[/code], any depenetration from the recovery phase is also reported as a collision; this is used e.g. by [CharacterBody2D] for improving floor detection during floor snapping. Removes a body from the list of bodies that this body can't collide with. Checks for collisions without moving the body. In order to be frame rate independent in [method Node._physics_process] or [method Node._process], [param motion] should be computed using [code]delta[/code]. Virtually sets the node's position, scale and rotation to that of the given [Transform2D], then tries to move the body along the vector [param motion]. Returns [code]true[/code] if a collision would stop the body from moving along the whole path. [param collision] is an optional object of type [KinematicCollision2D], which contains additional information about the collision when stopped, or when touching another body along the motion. [param safe_margin] is the extra margin used for collision recovery (see [member CharacterBody2D.safe_margin] for more details). If [param recovery_as_collision] is [code]true[/code], any depenetration from the recovery phase is also reported as a collision; this is useful for checking whether the body would [i]touch[/i] any other bodies.
