<description>
Kinematic bodies are special types of bodies that are meant to be user-controlled. They are not affected by physics at all; to other types of bodies, such as a character or a rigid body, these are the same as a static body. However, they have two main uses:
[b]Simulated motion:[/b] When these bodies are moved manually, either from code or from an [AnimationPlayer] (with [member AnimationPlayer.playback_process_mode] set to "physics"), the physics will automatically compute an estimate of their linear and angular velocity. This makes them very useful for moving platforms or other AnimationPlayer-controlled objects (like a door, a bridge that opens, etc).
[b]Kinematic characters:[/b] KinematicBody2D also has an API for moving objects (the [method move_and_collide] and [method move_and_slide] methods) while performing collision tests. This makes them really useful to implement characters that collide against a world, but that don't require advanced physics.

Returns a [KinematicCollision2D], which contains information about a collision that occurred during the last [method move_and_slide] call. Since the body can collide several times in a single call to [method move_and_slide], you must specify the index of the collision in the range 0 to ([method get_slide_count] - 1).

Moves the body along a vector. If the body collides with another, it will slide along the other body rather than stop immediately. If the other body is a [KinematicBody2D] or [RigidBody2D], it will also be affected by the motion of the other body. You can use this to make moving or rotating platforms, or to make nodes push other nodes.

You can use this to make moving and rotating platforms, or to make nodes push other nodes.
This method should be used in [method Node._physics_process] (or in a method called by [method Node._physics_process]), as it uses the physics step's [code]delta[/code] value automatically in calculations. Otherwise, the simulation will run at an incorrect speed.
[code]linear_velocity[/code] is the velocity vector in pixels per second. Unlike in [method move_and_collide], you should [i]not[/i] multiply it by [code]delta[/code] — the physics engine handles applying the velocity.
[code]up_direction[/code] is the up direction, used to determine what is a wall and what is a floor or a ceiling. If set to the default value of [code]Vector2(0, 0)[/code], everything is considered a wall. This is useful for topdown games.
