Bullet wound could not hit

create invisible and not hurting aemitter you must do.

How to do that in order for the wound to cancel

Hah this is getting lousy... alright let's get this done.

I assume you are talking about making the particles don't hurt the AHuman which you're playing,
You can do this using;

- .ini format which would be simplier and you would only have to set "GetHitByMOs = 0" just as
zalo did on his "ghost clone", but the bullets would trespass your little boy creating a weird feeling
like there is some kind of ghost OR making the material of the soldier very very dense and resilient,
just like Shook did with his first "Resilient soldier MK1".

- .lua format which would be significant more difficult to do, there are countless way to script
an un-pierce-able soldier, all of them unbelievable tricky, I recommend you to NOT pick this choice.

The first choice of the enemy will not shoot me

What am I gonna do

Well, the first thing you should do is take a crash course in english because all you wrote is gibberish.
I also wonder why you're continuously quoting yourself.

I mean no offense with the above, but do know that it'll be impossible for others to help you when they have no clue what you're going on about.

This week's kudos go to Naxx for trying to decipher this mess.

How do know Christmas

I think he wants to know how to remove wounds from actors for a health-pack or something....

That isn't possible without replacing the entire actor.
