TFS 1.X+ How much mana/health gain on potion heal.

Wondering if there's any way to show how much mana/health gain is made when a potion is used. This would be replacing the "Aaaaah..." which it normally casts.

here's the code that I use:

Lua: 
local config = {
lvl = 1, -- the multiplier for how much level matters. Default 1.
mlvl = 2, -- the mulitplier for how much mlvl matters. Default 1.
forMin = 0.9, -- forumula multiplier for MIN/max range. Default 0.9 == 90%          --Change both to 1.0 for amount healed to have no min/max
forMax = 1.1, -- forumula multiplier for min/MAX range. Default 0.9 == 110%          --Change both to 1.0 for amount healed to have no min/max
removeOnUse = false, -- Does this remove 1 potion after it's use? true/false          -- Default true.
useOnSummons = true, -- Can you use this on a players summon? true/false              -- Default true.
useOnGuildSummon = true, -- Can you use this on guild mate's summon? true/false      -- Default true.
useOnPartySummon = true, -- Can you use this on a party members summon? true/false      -- Default true.
realPvpMode = false, -- True = Players can't use potions for hotkeys || False = Players are allowed to use potions for hotkeys.
exhaust = Condition(CONDITION_EXHAUST_HEAL, CONDITIONID_HEAD), --Condition for each specific potion.Adjust time in potions table below.
cooldown =  Condition(CONDITION_SPELLCOOLDOWN, CONDITIONID_HEAD) -- Condition for creating "groups" of potions with same cooldown time, eg. all mana potions.
}
local POTIONS = {

There's a formula.

Lua: 
if health == true then
    target:addHealth(( math.random((((healthmax/100)*hpPercent ) + ((level/12)*config.lvl ) + ((mlevel/18)*config.mlvl ))*config.forMin, ((((healthmax/100)*hpPercent ) + ((level/12)*config.lvl )+ ((mlevel/18))*config.mlvl )*config.forMax))))
end
if mana == true then
    target:addMana(( math.random((((manamax/100)*mpPercent ) + ((level/18)*config.lvl ) + ((mlevel/12)*config.mlvl ))*config.forMin, ((((manamax/100)*mpPercent ) + ((level/18)*config.lvl )+ ((mlevel/12))*config.mlvl )*config.forMax))))
end

You may change this:

Code: 
lvl = 1, -- the multiplier for how much level matters. Default 1.
mlvl = 2, -- the mulitplier for how much mlvl matters. Default 1.
forMin = 0.9, -- forumula multiplier for MIN/max range. Default 0.9 == 90%          --Change both to 1.0 for amount healed to have no min/max
forMax = 1.1, -- forumula multiplier for min/MAX range. Default 0.9 == 110%          --Change both to 1.0 for amount healed to have no min/max

and
Code: 
healthpercent =
manapercent =

in
Code: 
local POTIONS

cooldown =  Condition(CONDITION_SPELLCOOLDOWN, CONDITIONID_HEAD) -- Condition for creating "groups" of potions with same cooldown time, eg. all mana potions.

What formula? I want to change the output from "Aaaah..." when a potion is used, to make it show how much it healed.

Example: "+1234" instead of "Aaaah..."

Thanks dude! Added .."" after the formula and it worked!

Like this:

Lua: 
 target:say("+"..(( math.random((((level)*config.lvl ) + ((mlevel)*config.mlvl ))*config.forMin, ((((level)*config.lvl )+ ((mlevel))*config.mlvl )*config.forMax)))).."", TALKTYPE_MONSTER_SAY)

*changed the formula some for more balance*

Yeah it's nice, one detail tho. The problem with that formula is that it shows a random amount, not the actual heal.

Example: I heal for 550 mana (actual heal) and it shows a random amount between the min and max in the formula, this since we use math.random.

Is there any way for it to calculate what was healed and then show the correct amount?

Make a variable to hold it, calculate it once, pass it to the relevant callback functions to output text. It'll clean up your code and make it more readable if your equation is outside the if, and is only done once. It can then be used. As it stands you are generating different random numbers for healing and textual output.

Idk how to do this, can you explain?

For instance:
Lua: 
local healthToAdd = ( math.random((((healthmax/100)*hpPercent ) + ((level/12)*config.lvl ) + ((mlevel/18)*config.mlvl ))*config.forMin, ((((healthmax/100)*hpPercent ) + ((level/12)*config.lvl )+ ((mlevel/18))*config.mlvl )*config.forMax)))

if health == true then
    target:addHealth(healthToAdd)
end

local manaToAdd = ( math.random((((manamax/100)*mpPercent ) + ((level/18)*config.lvl ) + ((mlevel/12)*config.mlvl ))*config.forMin, ((((manamax/100)*mpPercent ) + ((level/18)*config.lvl )+ ((mlevel/12))*config.mlvl )*config.forMax)))

if mana == true then
    target:addMana(manaToAdd)
end

Then you can reuse healthToAdd and manaToAdd to output the text, such that your health/mana increase is consistent with the value displayed in the textual effects.

Nice! Just as I imagined.
Store the formula as a variable then call it in the function XD

Thanks for the help, but that last version you sent didn't work.

For any one wanting this here's the script for GMP, you can easy add other potions or change it to another potion.

Lua: 
local config = {
lvl = 1, -- the multiplier for how much level matters. Default 1.
mlvl = 2, -- the mulitplier for how much mlvl matters. Default 1.
forMin = 1.0, -- forumula multiplier for MIN/max range. Default 0.9 == 90%          --Change both to 1.0 for amount healed to have no min/max
forMax = 1.1, -- forumula multiplier for min/MAX range. Default 0.9 == 110%          --Change both to 1.0 for amount healed to have no min/max
removeOnUse = false, -- Does this remove 1 potion after it's use? true/false          -- Default true.
useOnSummons = true, -- Can you use this on a players summon? true/false              -- Default true.
useOnGuildSummon = true, -- Can you use this on guild mate's summon? true/false      -- Default true.
useOnPartySummon = true, -- Can you use this on a party members summon? true/false      -- Default true.
realPvpMode = false, -- True = Players can't use potions for hotkeys || False = Players are allowed to use potions for hotkeys.
exhaust = Condition(CONDITION_EXHAUST_HEAL, CONDITIONID_HEAD), --Condition for each specific potion.Adjust time in potions table below.
cooldown =  Condition(CONDITION_SPELLCOOLDOWN, CONDITIONID_HEAD) -- Condition for creating "groups" of potions with same cooldown time, eg. all mana potions.
}
local POTIONS = {
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  [7590] = {empty = 7635, spellid = 3, splash = 7, exhaust = 300, health = false, mana = true, lvlReq = 80, vocations = {1, 2, 5, 6, 11, 12}},                             -- great mana potion
