To assign a Vector3 to System.Object

Hello,

I'm tryin to assign a Vector3 object into a System.Object variable. But if i don't create a Vector3 variable it doesn't work and i don't understand why.

here is my code :

Code (CSharp):

1. System.Object result;
2.  
3. // ...
4.  
5. result = Vector3.zero;
6.  
7. Ray ray = this._camera.ScreenPointToRay(Input.mousePosition);
8. RaycastHit hit;
9.  
10. if (Physics.Raycast(ray, out hit, (this._camera.transform.position.y + 10f))){
11.     result = new Vector3(hit.point.x, 0, hit.point.z);    // result = (0, 0, 0) => NON OK
12.  
13.     Vector3 test = new Vector3(hit.point.x, 0, hit.point.
14.     result = test;                                                         // result = (x, 0, z) => OK
15. }

Do you have an idea why the first assignation doesn't work and the second do ?

Thanks

 

Sorry, this might not be a satisfying answer.

You can assign most objects to System.Object because most objects inherit from another class that inherits from a C# System.Object. Vector3 is a struct created by Unity (not built into C#) and does not inherit from anything, so Vector3 data can only be stored in a Vector3 unless it's converted.

Basic types like "int" and "float" use some black-box magic behind the scenes to allow them to be stored in a System.Object. The best way to sum it up is that they get converted to a System.Object automatically.

If you want more info on any of this, the first answer to this question has a lot of great info: https://stackoverflow.com/questions...-object-referencetype-and-still-be-valuetypes

 

Hello,

Your answer is perfect.
I didn't noticed that an Unity Object was not necessary a System.Object's child.

Thanks !
