[solved] Jump spin attack

[Hax0r]

Can you tell me how do this attack?:
While jumping i press attack and do normal jump_attack
But when press jump again (while in air, jumping fames) start to spins around until hit the ground.
I was trying to do that by adding hit_j: (attack fame) but don't work please help me ;/
And i don't want to delete the jump_attack.
