Animation and Character BP Design UE4

I will need you to create a character and animation blueprint, that will have prone, crouch, standing and running, with rifle pistol and melee. I would like prone setup to the x key, and togglable so when its pressed the player will be prone until they press the X key or crouch key. I could like the same setup for crouch toggleable, but using the c/left ctrl button. Sprinting should be a press and hold to use on the shift key.
