Need help with E2 for Observation Drohne

[Nompl]

I'm new to E2 and only know the basics. I'm currently working on a Chip that turns a Hoverball Prop into a Observation Drohne. I already got the Drohne to fly around with applyForce() but need some help with the following:
-Can I disalble/enable the Gravitation for the Prop with E2 (Change Physical Proberties)
-Can I make the entity aim in the same direction like me? (Doesn't aim at the same point like me, aim in the same direction)
-Is there a script that allows me to use a virtual cam (like the CamController) with E2 so I don't have to use the CamController?
I already searched for these things but didn't found helpful results, so I'm sorry if these Questions were already answered but I didn't find them. Thanks for reading.

1) No.
2) I believe you want to use the owner():eyeAngles() to do that
3) No.

Thanks alot

Is there any other way to keep a Object in the Air? I already tried to keep something with applyForce() in the air but that conflicts if other apply Force functions running at the sime time for the same object. setMass also doesn't affect the Gravitation so I don't know how to do this.

Have it in an if statement, so say you wanted to have it flying, then hovering you'd do this

if(Fly == 1) {E:applyForce(whatever)} else {E:applyForce(vec(0,0,E:mass()*9.015))}

the E:applyForce(vec(0,0,E:mass()*9.015)) bit makes it hover where it is.

Correct me if I'm wrong anyone.

9.015 is the rough formula to "defy gravity". It in no way keeps it in the same location. It actually floats upward a bit.

Vec = (HovHe - Weldedto:massCenter():z())*vec(0,0,1)* 1.35 * Weldedto:mass()
Weldedto:applyForce(Vec - Weldedto:vel() * 30)

Works, where HovHe is the z value you want your craft to hover at.

Uh doiii, physical properties? Choose the physical properties tool and uncheck "toggle gravity" and set the properties to whatever you want. Shoot the object and e2 chip on it... Viola, no gravity.

(As an alternative to using their method)

I tried this, but the object isn't holdable at a specific ponint. If you move it forward, it hovers up and it conflicts if you give the object another Up/Down command.

Also I tried this out, but is there any way to do this without giving the Chip the Y-Coordinate where to fly, I mean so you can change the hight by applyForce...Up() and -Up()? With your method it's only possible to do it with changing the coordinates slowly I think. I'll soon post the whole code of the Chip here, so it's maybe easyer to understand my problem, I can't explain it very well because of my limited english knowledge .

Yes, I know the tools, but I don't know much about E2 so I asked how to do it with E2.

But thank you all very much for your help.

EDIT:
Here's the code. Some parts are in german, sorry. Feel free to use it for fun :

    }
    if(Up != 0)
    {
        EE:applyForce(vec(0,0,5))
    }
    if(Down != 0)
    {
        EE:applyForce(vec(0,0,-5))
    }
    if(TurnL != 0)
    {
        EE:applyAngForce(ang(0,2,0))
    }
    if(TurnR != 0)
    {
        EE:applyAngForce(ang(0,-2,0))
    }
#-------------------------------------------------------
}
else
{
    KameraAn=0
    Sound=0
    soundStop(0)
}

I'm sure it is a terrible code but how I already said, I just started.

I believe Unsmart's server had a entity: propGravity(boolean) function. It might be a part of propcore. If not, I can make it really quick in Lua...

Thanks, it worked. I'll post the whole Code here again, when its done.
