Holds collision data from the movement of a [PhysicsBody2D]. Holds collision data from the movement of a [PhysicsBody2D], usually from [method PhysicsBody2D.move_and_collide]. When a [PhysicsBody2D] is moved, it stops if it detects a collision with another body. If a collision is detected, a [KinematicCollision2D] object is returned. The collision data includes the colliding object, the remaining motion, and the collision position. This data can be used to determine a custom response to the collision. Returns the collision angle according to [param up_direction], which is [constant Vector2.UP] by default. This value is always positive. Returns the colliding body's attached [Object]. Returns the unique instance ID of the colliding body's attached [Object]. See [method Object.get_instance_id]. Returns the colliding body's [RID] used by the [PhysicsServer2D]. Returns the colliding body's shape. Returns the colliding body's shape index. See [CollisionObject2D]. Returns the colliding body's velocity. Returns the colliding body's length of overlap along the collision normal. Returns the moving object's colliding shape. Returns the colliding body's shape's normal at the point of collision. Returns the point of collision in global coordinates. Returns the moving object's remaining movement vector. Returns the moving object's travel before collision.
