Hi there, my arms walking animation is not playing when I move the character.
Here are my Event Graph, Transition Rule from Idle to Walking and the Walking State

Any advice much appreciated
Your boolean check for movement speed will only be true if movement speed is below zero (or said more literally to the picture, when zero is greater than your movement speed)
Move the vectorlength connection to the top connection of the greater-than node.
Hey Tuomo,
Literally just figured that out before you replied 
Thanks anyway !
