Which Function is Faster?

[BlueBerryWizard]

Which is faster?


My script:

• Unit Get Nearest
  • Options: Action
  • Return Type: Unit
  • Parameters
    • Unit = No Unit <Unit>
    • Group = (Empty unit group) <Unit Group>
  • Grammar Text: Unit Get Nearest(Unit, Group)
  • Hint Text: Makes the units seek out enemy units and attack them.
  • Custom Script Code
  • Local Variables
  • Actions
    • General - Custom Script: unit lv_u;...

unit lv_u;
unit lv_u2;
point lv_pt = UnitGetPosition(lp_unit);
point lv_pt2;
fixed lv_distance;
fixed lv_distance2 = 10000.0;
UnitGroupLoopBegin(lp_group);
while (!UnitGroupLoopDone()) {
    lv_u  = UnitGroupLoopCurrent();
    lv_pt2 = UnitGetPosition(lv_u);
    lv_distance = DistanceBetweenPoints(lv_pt, lv_pt2);
    if (lv_distance < lv_distance2) {
        lv_distance2 = lv_distance;
        lv_u2 = lv_u;
    }
    UnitGroupLoopStep();
}
UnitGroupLoopEnd();
return lv_u2;

OR

UnitGroupClosestToPoint(Unit Group, Point);

 

[Dr Super Good]

UnitGroupClosestToPoint(Unit Group, Point);

This should be faster as it is a native function thus all its mechanisims are probably highly optimized (more so that any galaxy script can be).

Remember that galaxy opperates via a virtual machine which interpretes instructions at runtime. Although this is a lot faster than how JASS opperated in WC3 which was a purly interpreted language, it still is slower than nativly run code (which UnitGroupClosestToPoint should use). It might also use more advanced algorthims with a better than O(n) complexity.
