Make a pawn move(going to be my lizard character)

Ok, so here Blueprint Creating a Tank | Live Training | Unreal Engine - YouTube
the guy is making a tank , which is different , but the point is that he is making it from a pawn, and he is using “Add Actor Local offset” to make it move and i think that if i can get that offset and somehow make that offset to change the value of my variable Speed(which I am using in my AnimBP, to blend between walk and idle animations), maybe that can do the trick, but since i am new i can’t casting to another blueprint to work , so i can read my variable Speed , which is set in another blueprint.(my “AnimBP”).
I ended up making the Collision object for my static meshes a lot bigger than the actual meshes and now the collision happens before my lizards “enters” in the mesh , some sort of a workaround, but i guess not going to work for more complex projects.
