distance thingy

local function getDist(x1, y1, x2, y2)
    --local dist = math.sqrt( (math.abs(x1-x2) ^ 2) + (math.abs(y1-y2) ^ 2) )
    local minDist = math.floor( math.sqrt( (math.abs(x1-x2-1) ^ 2) + (math.abs(y1-y2-1) ^ 2) ) )
    local maxDist = math.floor( math.sqrt( (math.abs(x1-x2+1) ^ 2) + (math.abs(y1-y2+1) ^ 2) ) )
    print("min = "..minDist.. ", max = "..maxDist)
    local dist = math.random(minDist, maxDist)
    return dist
