Hello guys, i have this persisten but it isnt work nice, doesnt fish the waters most of times, he press the hotkey, but doesnt use in water corpse.. any ideas? i tried to use persistent included in cavebot but doesnt work aswell, same problem but a bit more bugged...

init start
-- local SCRIPT_VERSION = '1.1.1'

-- If set to true, will pause walking and wait for fresh bodies to become
-- 'fisable'.
local waitFresh = false


-- DO NOT EDIT BELOW THIS LINE --

local fishLoot = {281, 282, 3026, 3029, 3032, 9303}

-- I wish I could have made this a more generic function, but it would most
-- likely make it less efficient for the current use case; I know... I will
-- pay for that in the future. Meh... whatever, bring it on!
local function findwaterfishspots(exceptClose)
local hasFresh = false

for x = -7, 7 do
for y = -5, 5 do
-- This lets us ignore bodies that are too close and might fuck
-- up because of character's first movements, but still account
-- for them after it's already standing.
if not exceptClose or (math.abs(x) > 1 or math.abs(y) > 1) then
local curX, curY = $posx + x, $posy + y
local item = topuseonitem(curX, curY, $posz).id

if item == 9582 then
return {x = curX, y = curY}
elseif item == 4037 then
hasFresh = true
end
end
end
end

return nil, hasFresh
end
init end

auto(100)

if $lootsaround == 0 and $targetingtarget.hppc == 0 then
local old, fresh = findwaterfishspots(true)

while old ~= nil or (waitFresh and fresh) do
pausewalking(6^9) -- Yeah babe!

if old ~= nil then
local itemCount = {}

for _, v in ipairs(fishLoot) do
itemCount[v] = itemcount(v)
end

useitemon(3483, 0, ground(old.x, old.y, $posz))
waitping()

for _, v in ipairs(fishLoot) do
local curCount = itemcount(v)

if curCount > itemCount[v] then
increaseamountlooted(v, curCount - itemCount[v])
end
end
end

-- If starting conditions are no longer met, abort mission!
if $lootsaround ~= 0 or $targetingtarget.hppc ~= 0 then
break
end

old, fresh = findwaterfishspots(false)

pausewalking(0) -- Orgasm.
