How to connect all child objects with a Fixed Joint component?

Question

Unity

I have a Car object that has n Detail children. How can I add a Fixed Joint to each of these objects, which will be connected to the rest?

Answer 1

private void JoinChildrens()
{
var rig = GetComponent();
for(int i = 0; i < transform.childCount; i++)
{
var fix = transform.GetChild(i).gameObject.AddComponent();
fix.connectedBody = rig;
}
}
