Hey,
is it possible to store an object/prefab which is hit by a ray into a variable, so that i can change the objects transform to follow the mouse position. And if it is how i can do it?

Yep, of course:

Transform hitObject;

void PerformRaycast() {
  if (Physics.Raycast(someRay, out RaycastHit hit)) {
    hitObject = hit.transform;
  }
}

So hitObject now got the transform of the hit object in scene. But how can i then change the transform of the hit object.
I tried this but it didnt work :confused:

Ray ray2 = Camera.main.ScreenPointToRay(Input.mousePosition);

if (Physics.Raycast(ray2, out RaycastHit hit))
{
hit.transform = Input.mousePosition;
}

Once you have stored the hitObject variable you can modify it by assigning a value to hitObject.position

Instead of randomly trying code, I suggest you type the title of this post into Google.

Otherwise you’re going to spin and spin and spin on what is like a 60-second problem.

For instance, in the second block of code, hit.transform is a read-only property, so you cannot assign to it.

For two, you generally cannot assign the mouse position directly to a transform and have it do anything meaningful. There are Camera component cast functions you can use.

Look up a tutorial, the time you save will be your own.
