Ok… this is a bit “Goblin Solution” but it work at least with the normal Combos and not with the special attacks . Why this is a “Goblin Solution”? because I don’t get the new direction from gamepad or the keyboard i Just stop the character where he is and thanks to the AnimNote I let for a bit change the direction for the next attack. This solution had a great problem with the special attacks because right now with the actual blueprint (tutorial 4/6) the special attack don’t wait to the animation to end to do the new animation so sometimes this works… and sometimes don’t before do the slam
video with this implemented (Sorry for the Music, I like to use music and sounds on my test levels )

I will try to optimice this to the maximum and if someone get new ideas for solve this is welcome 
Also I think if we save the actual direction of the current attack and make a Branch to see if the next attack is in the opposite we can use a different animation to show the changing direction of the attack to the new one like in the Witcher III game
I will try to see if I can do it tomorrow
