How can find Center of circle to Unity? - unity3d

I have circle, and I'm trying to find center and convert to Vector2.
For example:
circleLocation : new Rect( Screen.width/10, Screen.height/2.75, Screen.width/3,Screen.width/3);
centerofcirle:New Vector2(circleLocation.width/3, circleLocation.height/3);
But this example's not correct, the circle is not turn center. What is this formula? How can find correct center of cirle and how to convert Vector2?

Reading between the lines here, I wonder if issue has nothing to do with your code here, but with the rotation point of your steering wheel object, which isn't where you want it to be.
A common technique to change the rotation point of a game object is to make that object the child of another game object in the Unity Editor. Then set the position of the child object as you wish relative to the position of the parent object. Now, rotate the parent object. The child object will automatically rotate around the parent object's position, since it's transform (including position/rotation) is relative to it's parent's.

You seem to be defining your circle using a Rect so just use the Rect.center property:
circleLocation.center;

Rotate a body about a given point Unity2d

How to rotate a body relative to given dx dy in Unity? For example, I have a weapon sprite with a hand, and I was able to make it rotate relative to its center so that the weapon looks at the cursor, how can I rotate not relative to the center of the sprite, but relative to a given point?
The simplest way to achieve this is to set a gameobject at your desired point and make your object child of the created object. So when you rotate the parent, it will rotate relative to the parent point.
You can create an empty object and set the body as its child, then rotate the parent, the body will rotate around the parent like the parent be its pivot.
This is a practical way to set the pivot, and you can change it at any time.

Unity Gameobject is far away from the Move Tool

why is my Gameobject so far away from the Move Tool as you can see in the Picture down below?
I would like to have it centered at the Gameobject. How can I change this?
GameObject away from Move Tool
Screenshot of Hierarchy
Check the object in the scene hierarchy and make sure that the transform eg. x,y,z are set to 0.
If your object is a child of another object and they are not at the same position you are probably moving the parent and not the child object itself.
that Move Tool is the objects origin, and this might help:
"The easiest way is to create an empty object as a parent object. Then you put the corridor object as a child of the empty object. You can then alter the position of the corridor object so its positioned at the edge.
i found your answer here
note that its not exact, in your case, make an empty object, move it to where you would like your origin or move tool THEN add your other object to it as a child. you can then move it with the parents move tool(origin) right on top of your box.

How to find the center in unity 2d?

I want to create 2d game. The game is similar to the Scale Puzzle. I've already created nearly all the functionality. Only the last remains.
.
This is example.
And that's how I draw shapes.
.
I click inside a white square, and after 1 seconds a square is drawn regardless of the position of the ball. (x,y).
Square is created programmatically, and it is added to the parent element "SquaresList" with name New Game Object.
How can i do, so that the violet field becomes larger, and in the middle of the screen.
I made it so that for every 3 clicks, "SquaresList" increases Scale by 0.25f, and get negative position of the ball. Example:
SquareList.transform.position = new Vector2(-ball.pos.x, -ball.pos.y)
This does not work correctly.
What options can be? (intersections, find the max/min point, math formulas) ?
Hi NoName :) Your method
SquareList.transform.position = new Vector2(-ball.pos.x, -ball.pos.y)
would work perfectly if your object does not inherit other objects and there positions. To fix this make sure that you reset the position of all other game objects that you use as containers.

Positions of objects in the scene

My hierarchy of game objects is as follow.
Display(Scene)
Model(-4.708, 1.55, 14.4277)
Pass(4.7080, -1.5, -14.42)
handle(-0.0236,0.65690,0.149)
shaft(5.34,-1.0225,-0.1489)
head(-7.0912,-9.62,-0.5231)​
ball(0,0,0)
We can see Model and its coordinate on the image. Ball has position (0,0,0), but why it is located at the base of the Model?
How can I locate ball just beside the head?
Sounds like the origin point of one or more of the models is at off.
You can adjust this in 3d modelling software, or by making an empty game object inside unity and making your object a child of that object, then using the empty game object as the new origin point, you can adjust the positions of the child objects you assign to it.

Rotate an object with RotateAround to a specific value

I'm new in unity engine and try to rotate an object to specific value, but could not find any answer!
For example, I have an Euler angles (0,0,48) and my object in (0,0,340). I want give (0,0,48) values to my object with RotateAround() function to my object. Because it should rotate around of a point!
Unless you have a point in space you wish to rotate through, use Transform.Rotate(). that should be more than enough for you to rotate an object by (0,0,48) like you said.
