1st How can i make gun shoot in that person who takes the gun, and that gun heals that person ? 2nd can an actor have 4 legs ? or crab have 4 same way legs Pic -> . Is this possible ?
3rd Can i make red glows ?

1. Take a look at the medikits by TheLastBanana, it does exactly this. But, healing happens only through Health. You cannot heal wounds or gibs.
2. No, but you can make the sprite look in a way that one leg looks like 2.
3. Yes, but only sprite glows, you cant change the pixel hardcoded glows.

Thx.About 2nd will it walk ?

Edit: I need Rupiblic Commando heal thing.That can do it with effects.Is it possible ?

I'm not going to warn you for this one, but seriously, stop posting threads with terribly uninformative titles.

Heal how?

Those heals are good, but the havent any glows\effects.
I want make an actor , he will be controled 1-CPU(green) team.He will have this gun.The actor will cant move.So when you walk close to the thing.It shots some king of glows in you , and then you get healed.Is this possible?

Nope, the way the medipacks work is they make a custom wound in your arm, this wound does negative damage thus healing you. You can only make these custom wounds on your self.

Ok.But i can realise this other idea.It would be pickupable station , like in republic commando.Plzzzz Roon3 plzzzzz make super battle droid sprites.PLEASE I WILL DO ALL WHAT YOU WANT PLZZZZZZ I REALLY NEED HIM

No droid sprites, I'm busy helping Gotcha! (Maybe when I'm done).
About the gun it has to break in order for it to heal your actor, (It creates a break wound (I think) with negative emission damage) you could always make it gib another gun, (using the phoenix-bot code...) but then it would be indestructible.

AAAAAAAAAAAAAAh!... now i do understand how it works...
