[Tutorial] Spawn particles when hiting a living entity Tool (cooldown)

So lately i been working on a new feature for Tools, that when you hit a entity it appears a particle + bonus damage, so last month i was searching for a tutorial that help my making this feature, but there was nothing, so i make one and today i finished what i think is the more complex thing that i ever made in Mccreator (On my own). 

1. Its important to Know that you need a Global Logic Variable (Variable scope PLAYER_LIFETIME) before proceeding.

2. Create a second Procedure that apply the cooldown (for what i testing is imposible to do it in the same procedure)

3.heres a in game example 

I think The Procedures Could be a lot better, ask my if you have any problems.
