--dx/dy collation logic for copykat moves
if (data.reason == "copkat") then
  --new 'move ALL the way' logic:
  --1) Split the move into two parts - all the diagonal movement, then all the remaining orthogonal movement.
  --2) Put the second half in as a new move after this one.
  local diag_amt = math.min(math.abs(data.dx), math.abs(data.dy));
  local ortho_amt = math.max(math.abs(data.dx), math.abs(data.dy)) - diag_amt;
  if (diag_amt == 0 and ortho_amt == 0 or slippers[unit.id] ~= nil or hasProperty(unit, "slep")) then
    data.times = 0;
  elseif (diag_amt > 0 and ortho_amt == 0) or (ortho_amt > 0 and diag_amt == 0) then
    data.times = math.max(diag_amt, ortho_amt);
    local dir = dirs8_by_offset[sign(data.dx)][sign(data.dy)];
    data.dir = dir;

  else
    local newdir = dirs8_by_offset[sign(math.abs(data.dx)-diag_amt)][sign(math.abs(data.dy)-diag_amt)]
