Advice on how to finish my 8 directional walk & Idle for Paper 2d

I have read the Unreal Engine 4 Documentation many times about setting up a State Machine:

Step1) Have Flipbook Animations for each of the animation states you want your character to enter.

Step2) Add and set them as Flipbook variables inside your Paper 2D Character Blueprint.

Step3) Add each of the states to the Animation State Enumeration we created.

  1. Create conditions that determine when the character can enter each state and add it to the Anim State Machine function.

  2. Connect each of your Flipbook variables to the Select node inside the Anim State Machine function.

I already finished most of this ( see my project pictures below)

My question is does anyone have advice creating conditions that would determine a 8 directional walk and idle for paper 2D that would finish off my Animation State and Event Graph?
