I'm getting this error:

 

 Assets/CircularOrbit.js(11,26): BCE0023: No appropriate version of 'UnityEngine.Transform.RotateAround' for the      argument list '(UnityEngine.Vector3, System.Type, float)' was found.

 

Here is my script:

 

#pragma strict
 
function Start () {
 
}
 
function Update () {
   var mountain : GameObject;
// This will return the game object named Hand in the scene.
   mountain = GameObject.Find("QuantumCold_B");
   transform.RotateAround(mountain.transform.position, Vector2,20 * Time.deltaTime);
   
}
 
What I am trying to do is circle around a mountain object which is a mesh.

the 2nd parameter looks wrong. Instead of just Vector2, try Vector3.Up,

 

The 2nd param is the axis that the rotation is to be around. that axis must be in 3d space so it needs a Vector3. Most likely, you want Vector3.Up for it.

transform.RotateAround(mountain.transform.position, Vector2,20 * Time.deltaTime);

 

I'm going to guess that the bolded part is supposed to be the rotation axis? If so, you should actually pass it an axis, ie. an instance of a Vector3. Right now you're passing it the type Vector2. RotateAround() expects two Vector3s and a float, and right now you're giving it a Vector3, a type, and a float, just like the error message says.

 

Next time you can solve something like this more quickly by reading what the error message is saying. If you compared the error message to the actual function signature of RotateAround (found [url=http://docs.unity3d.com/Documentation/ScriptReference/Transform.RotateAround.html]here[/url]), I think you would have spotted the problem pretty quickly. Error messages are there for a reason. ;)

      well, i have started developing games last year, alone , I made a singleplayer 3d openworld rpg on unity you can look at it on googleplaystore ( kooru stone rpg ) whatever, this year, i wanted to make mmo, which gone really fine until I first try real hosting, I was working on "wamp" until then. The reason i am desperate now is that the way my game works.
      On my pc, using wamp mysql , with localhost as host for my game, i was testing my mmorpg with using andorid emulators, ofcourse no lag no issues no restrictions, beautiful dream... But then, I wanted to get real host from web, so, I rent a basic, cheaphest ever web host ( 10$ year ), and transferred my php files along with sql database. 
      So, I launched the game, still no issues, tried to handle 2-3 players by using my pc, phone, friend's phone...  
      After a while, ( after really short time (3-4mins)) host started not to respond, beacause those web hosting were not fit to handle mmos, i predicted that.
      now what i am explaining is that my game works like this and asking what way should i use to handle it :
      - Creates web request ( like : webhost.com/game/getplayerdata.php?ID=2 )
      -Reads request ( request result be like = "ID2-GoodGuyXx-23-123-4-123-43 )
      -Builds player using result string
      -does similar requests REEAALY FREQUENTLY  ( total requests of 8 - 12 times per seconds )
      With my current ultimate cheap web hosting, i can handle 2 players with low lag ( lol ) but, i want to handle around 20-100 players,
      just need a clear path, i have been struggling with google cloud sql and other vps server dedicated server options, i dont wanna pay much and get ripped off.

      That planet is awesome!!! It's just slowly dissipating into space. Death by emmissions
      Love the green and yellow-orange juxtaposition (did I just say that?).

      I've been doing some digging and come to the conclusion that I'm not really qualified to identify a game engine for my project alone so I came here asking for some advice.
      My game idea involves movement inside a sphere where you always have your feet on the ground (the "walls" of the sphere), basically an inverted planet. It's supposed to be multiplayer so it's not just you moving in the world. When you jump, gravity (or force etc) pulls your character towards where it jumped from and the character model should have its feet pointing that way.
      I'm really new to this and my own conclusion is that it messes with core functionality of Unreal Engine 4 which makes it really hard for me as a beginner to wrap my head around. It comes with practice but It's hard for me to come to a fair conclusion on what engine to use based on my knowledge. Therefore I'm asking for some guidance. I have most experience with the Unreal Engine.
      What engine would you recommend?
      Is the game idea with being inside a sphere difficult to do in general? Do you have any tips?
      I'm kinda lost at the moment so thank you for the help!
