Hello Hive
I translated Merge Sort [GUI Friendly] v1.01 to Lua using cJass2Lua(v1.09) - Powerfull cJass and JASS converter and the map compiles fine without errors, and the merge sort is being ran. The problem is that I am getting unexpected results, and the units aren't properly sorted.
Furthermore one of the variables in one of the loops had to be changed for the map to even compile.
Doesn't compile;
Compiles;
Does anyone know what is going on?
Here's the translated code;
