Returns the last motion applied to the [CharacterBody2D] during the last call to [method move_and_slide]. The movement can be split into multiple motions when sliding occurs, and this method return the last one, which is useful to retrieve the current direction of the movement.

Returns the current real velocity since the last call to [method move_and_slide]. For example, when you climb a slope, you will move diagonally even though the velocity is horizontal. This method returns the diagonal movement, as opposed to [member motion_velocity] which returns the requested velocity.

Moves the body based on [member linear_velocity]. If the body collides with another, it will slide along the other body (by default only on floor) rather than stop immediately. If the other body is a [CharacterBody2D] or [RigidDynamicBody2D], it will also be affected by the motion of the other body. You can use this to make moving and rotating platforms, or to make nodes push other nodes.
Moves the body based on [member motion_velocity]. If the body collides with another, it will slide along the other body (by default only on floor) rather than stop immediately. If the other body is a [CharacterBody2D] or [RigidDynamicBody2D], it will also be affected by the motion of the other body. 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.
Modifies [member linear_velocity] if a slide collision occurred. To get the latest collision call [method get_last_slide_collision], for detailed information about collisions that occurred, use [method get_slide_collision].
Modifies [member motion_velocity] if a slide collision occurred. To get the latest collision call [method get_last_slide_collision], for detailed information about collisions that occurred, use [method get_slide_collision].
When the body touches a moving platform, the platform's velocity is automatically added to the body motion. If a collision occurs due to the platform's motion, it will always be first in the slide collisions.
The general behaviour and available properties change according to the [member motion_mode].
Returns [code]true[/code] if the body collided, otherwise, returns [code]false[/code].

As long as the snapping vector is in contact with the ground and the body moves against `up_direction`, the body will remain attached to the surface. Snapping is not applied if the body moves along `up_direction`, so it will be able to detach from the ground when jumping.
