Now setup the animations for the Frog:

We need access to the AnimatedSprite2D and its functions.

Create an onready reference variable for the AnimatedSprite2D.

We want to flip / mirror the sprite to look in the direction the player is facing

Do this my MOVING the direction variable from the run function

To the top of the player script.

Now create a new function to flip the animations 

depending on the value of the direction variable.

-1 = LEFT

+1 = RIGHT

Create a new function called animate

If the player is not moving we play idle

If the player is on the floor and moving up play jump

If the player is moving down play fall

if the player is moving left or right and not jumping play run

Double-jump and wall-slide will require their own functions.
