Lua Healing over time

[Northnorial]

I found the two following scripts here on OtLand,

the first one is not showing the healing damage,

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)

local condition = createConditionObject(CONDITION_REGENERATION)
setConditionParam(condition, CONDITION_PARAM_BUFF_SPELL, true)
setConditionParam(condition, CONDITION_PARAM_TICKS, 1 * 60 * 1000)
setConditionParam(condition, CONDITION_PARAM_HEALTHGAIN, 500)
setConditionParam(condition, CONDITION_PARAM_HEALTHTICKS, 3000)
setCombatCondition(combat, condition)

local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

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

the second tho is showing the healing damage,

healRegen = {}

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)

local condition = createConditionObject(CONDITION_REGENERATION)
setConditionParam(condition, CONDITION_PARAM_SUBID, 1)
setConditionParam(condition, CONDITION_PARAM_BUFF_SPELL, true)
setCombatCondition(combat, condition)

local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

function regen(cid,var,n)
n = n or 0
    if isPlayer(cid) then
        doCreatureAddHealth(cid, 20)
        if (n < 20) then
            healRegen[cid] = addEvent(regen, 3 * 1000, cid, var, n+1)
        end
    end
return true
end

function onCastSpell(cid, var)
    if healRegen[cid] then
        stopEvent(healRegen[cid])
    end
    doCombat(cid, combat, var)
    healRegen[cid] = addEvent(regen, 250, cid, var, 0)
return true
end

I could really use some explanation why the first one is and the second is not showing the healing damage.
Also I would like to know what numbers like if (n < 20) then or addEvent(regen, 250, cid, var, 0) do...

Thanks in advance!

The "n" variable is increased by one each round, "cid, var, n+1" I guess its supposed to be number?
The addEvent is what the function says, its a scheduled object that should be executed at (second parameter, in this case 3 * 1000 = 3 seconds).
So what the script does is to check if the n variable is below 20 then heal the player and then wait 3 second to repeat the function. It will also increase n by one for each round.

and what's the 250 supposed to mean?

and what's the 250 supposed to mean?

How quick it'll happen so 1000 is 1 second, so 250 is 1/4 of a second.
