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

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.

Is there a way to have a parent object follow the combined bounds box of the child objects?
I have child objects which I apply force to for movement (via `AddForceAtPosition). The problem is that they leave the parent behind in world space. I understand that children are relative to the parents position. But is there anything I can do to address this?
I'd really like to keep to keep the force being applied to the child object's rigid bodies as it gives me the physics behaviour I need.
I have experimented with getting the bounds of all child objects, then setting the transform of the parent to the children. But this causes jittery behaviour since moving the parent also moves the children.
There are two ways of doing this, the best way is to change the structure following:
A (parent)
B (child 1)
C (child 2)
to:
Root (new parent with nothing on it)
A (old parent)
B (old child 1)
C (old child 2)
Then move A the way you tried before. You might also want to look into Joints, and see if this might suit your need better. If you don't want two colliders to interact with each other, you might also want to look into Layer Based Collision Detection and Physics.IgnoreCollision().
An alternative that I really wouldn't recommend, is counteracting the movement of the parent with the children. So whenever you move the parent you move the local position of the child you want to stay still the opposite amount. This however could possibly make your physics wonky.
I have a 3d building model in my Unity project. It has many children like doors, walls etc. The problem is, all of the children points to same position in the Unity world (24.97, -2.08, 19.35). Their transforms show this position. And this position is far away from their actual one. How can i fix this?
I tried freeing all children from parent but this didn't change anything.
I want them to show their real position, which appears with move tool when we click upon them.
Here is the image link
It seems that this is simply their pivot point exported "wrongly" from the 3D editor your model was made with.
This won't change until you export it correctly from a 3D editor (Blender, Maya, etc).
Unity is not made for 3D mesh modeling and therefore in Unity itself you can't change the pivot points.
There is a very simple fix
Add a new empty GameObject
In the Inspector go to the Transform component, click on the context menu and hit Reset (you also simply set it to position 0,0,0 rotation 0,0,0 and scale 1,1,1) assuming the pivot should be at 0,0,0
Now drag and drop all objects into the empty GameObject
=> You have now one parent object with correct pivot.
By wrapping it in a parent object the childrens pivots don't matter anymore. You can simply do all translation, rotation and scaling on the parent object with the correct pivot and don't have to care about that "wrong" position at all.
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.
I have a unity game where I have a bunch of objects that are children of the player object. So when the player runs around, the children objects also run around relative to the player.
At the beginning of the game, I have a transform variable that stores the transform of one of the child objects, then i use that transform variable for the rest of the game to have the enemies use that to chase the children.
Transform childTransform=GameObject.Find("Parent").FindInChildren("child_1").transform;
But it seems this variable that points to the child transform, doesnt get updated to the current value when the parent moves. It just stays in the original position when i assigned it, so the enemy dont follow the current position, it just stays at the original position.
Maybe my code is wrong?
I thought it would get updated automatically to be the world space value of the child relative to the parent.
Anybody knows why? Do I have to constantly look up the child and reassign the variable each Update()? Isnt that a waste of CPU time?
Thanks
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;
