Heard that using foreach is not a good idea in update and that one should use a regular for.
How would you do that for the child transforms?
bool AllMembersDead()
{
for (int i = 0; i < transform.childCount; i++)
{
if(transform.GetChild(i).childCount > 0) return false;
}
return true;
}
OK, found it (with Unity 2017.1)
