I have created a custom bow and I want it to add a fire DoT (like a fire field) to the target when you fire regular arrows from it, I also want the arrow to do the same damage as it did before (not just adding a DoT) and when you use a regular bow the arrow works just like normal.

I have not managed to get it to work from the comments below:

lol, I found the problem, do this
LUA: 
local bowid = 22418
local condition = createConditionObject(CONDITION_FIRE)
    addDamageCondition(condition, 10, 2000, -10)
    setConditionParam(condition, CONDITION_PARAM_DELAYED, true)
local combat = createCombatObject()
    setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
    setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ARROW)
    setCombatFormula(combat, COMBAT_FORMULA_SKILL, 0, 0, 1, 0)
  
function onUseWeapon(cid, var)
    local slotleft = getPlayerSlotItem(cid,CONST_SLOT_LEFT)
    local slotright = getPlayerSlotItem(cid,CONST_SLOT_RIGHT)
    if slotleft.itemid == bowid or slotright.itemid == bowid and getCreatureTarget(cid) then...

This is the default poison arrow from the sources just change what you need such as the CONST_ANI_XXX effect COMBAT_XXX damage type & CONDITION_XXX and the addDamage values. :)

Yeah I tried doing that but it doesn't work. I think that's only for ammunition? I want the fire dot to be added only if you use the custom bow and a regular arrow, not a regular bow and a regular arrow.

I'm not getting any errors after adding the bow btw.

Strange, I'm not getting any errors and yet nothing happens. All the ID's are correct. I have checked plenty of times :o

Sorry replace

with
LUA:

Still nothing. Just fires arrows like regular :/

What am I to put in weapons.xml? Maybe I did something wrong there.

chance id in xml to whatever arrow you want and bowitemid in lua to whatever bow you want

Well that last script gave me an error.
Code: 
[18/4/2017 14:34:4] data/weapons/scripts/paladin/explosive arrow.lua
[18/4/2017 14:34:4] Description:
[18/4/2017 14:34:4] data/weapons/scripts/paladin/explosive arrow.lua:5: attempt to call method 'setParameter' (a nil value)
[18/4/2017 14:34:4] [Error - Event::checkScript] Cannot load script (data/weapons/scripts/paladin/explosive arrow.lua)

I don't think we understand each other here quite. I want the bow to still fire arrows that do regular damage but also adds the fire dot.
And 2546 is the burst arrow script and if I try to add anything in there I get errors.

Here is my current burst arrow script:

Code: 
local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_FIREAREA)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_BURSTARROW)
setCombatFormula(combat, COMBAT_FORMULA_LEVELMAGIC, 0, 0, 0, -150)

local area = createCombatArea( { {1, 1, 1}, {1, 3, 1}, {1, 1, 1} } )
setCombatArea(combat, area)

function onUseWeapon(cid, var)
    return doCombat(cid, combat, var)
end

We do understand each other here, you did something wrong

try this
LUA: 
local bowid = 22418
local combat = createCombatObject()
local combatnodot = createCombatObject()
for i, c in ipairs({combat,combatnodot}) do
    setCombatParam(c, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)

    setCombatParam(c, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_BURSTARROW)
    setCombatFormula(c, COMBAT_FORMULA_LEVELMAGIC, 0, 0, 0, -150)
end
local condition = createConditionObject(CONDITION_FIRE)
    addDamageCondition(condition, 10, 2000, -1)
    setConditionParam(condition, CONDITION_PARAM_DELAYED, true)
    setCombatCondition(combat, condition)
function onUseWeapon(cid, var)
    if getPlayerSlotItem(cid,CONST_SLOT_LEFT).itemid == bowid then
        return doCombat(cid, combat, var)
    else
        return doCombat(cid, combatnodot, var)

Yeah sorry, forgot to mention that.

Now it's going somewhere. But now only burst arrow adds a fire dot and it looks different and when the burst arrow lands it looks different, the old AoE is gone and it only effects 1 sqm. Shouldn't I add this with an arrow script instead?

what your asking for is very straightforward, you just need to clarify

in weapons.xml change
XML: 
    <distance id="2544" action="removecount"/> <!-- arrow -->
for
XML: 
    <distance id="2544" action="removecount" script="arrow.lua"/> <!-- arrow -->
and in arrow.lua:
LUA: 
local bowid = 22418
local combat = createCombatObject()
local combatnodot = createCombatObject()
    setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
    setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ARROW)
    setCombatParam(combat, COMBAT_FORMULA_SKILL, 0, 0, 1, 0)
    setCombatParam(combatnodot, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
    setCombatParam(combatnodot, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ARROW)
    setCombatParam(combatnodot, COMBAT_FORMULA_SKILL, 0, 0, 1, 0)
    setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_FIREAREA)
local condition = createConditionObject(CONDITION_FIRE)
    addDamageCondition(condition, 10, 2000, -1)
    setConditionParam(condition, CONDITION_PARAM_DELAYED, true)
    setCombatCondition(combat, condition)
function onUseWeapon(cid, var)
    if getPlayerSlotItem(cid,CONST_SLOT_LEFT).itemid == bowid then
        return doCombat(cid, combat, var)
    else
        return doCombat(cid, combatnodot, var)

Yeah I'm sick atm so having a hard time focusing on typing, hehe. But I have decided not trying to fix this, it doesn't seem to work. But like I said, I appreciate the help.
