There are parts of that I don't understand at all, like the
sorted_point logic, and this.next_move, so that limits what I
can suggest.

But you might prefer writing this with an eye on

https://dlang.org/spec/arrays.html#array-operations
https://dlang.org/phobos/std_exception.html#enforce

ex:

struct Mobile {
     int[3] pos, delta;

     void step() {
         import std.exception : enforce;

         pos[] += delta[];
         enforce(pos[] < [666, 666, 666], "example position 
violation");
     }
}

unittest {
     import std.stdio : writeln;

     auto m1 = Mobile([0, 0, 0], [5, 0, -1]);
     m1.step;
     m1.step;
     m1.step;
     writeln(m1);
}

unittest {
     import std.exception : assertThrown;

     auto m1 = Mobile([0, 0, 0], [1000, 1000, 1000]);
     m1.step.assertThrown; // position violation
}
