How do I make a hitbox on my sword

hey so i animated a sprite in spriter pro, and i set position of a green box within the slash of my sword for a hit box but i only want this box to appear when i hit the attack key and then have the box leave, that way anything that collides with this box is damaged

i'm streaming on twitch.tv/gusnation anyhelp here and or in my stream would be much appreciated

You can enable the box collision when hit then disable it.

i'm trying a different method at the moment , still having trouble

I figured this one out , in my Spriter Pro character attack animation i made a hit box within the animation , a feature i totally forgot about in the program and then when that box collides with enemy it gets destroyed . Problem Solved!!!
