I'm trying to put the magic exeta amp res, but it's giving this error, can someone help me?
Lua:
local function getDiagonalDistance(pos1, pos2)
local dstX = math.abs(pos1.x - pos2.x)
local dstY = math.abs(pos1.y - pos2.y)
if dstX > dstY then
return 14 * dstY + 10 * (dstX - dstY)
else
return 14 * dstX + 10 * (dstY - dstX)
end
end
