Like I said in my thread about new spells, here is the script I use to force a champion to have the scroll of a spell in his inventory or in his hand to be able to cast it. You can throw it in the file "init.lua" or anywhere you want, and normally it enough. Nothing more is required.
As usual some fine tuning can be doing if you want. Obviously you have to had a "if" bloc for each new spell if you had some custom ones. For now the variable spellUiName isn't used but you can use it to create a contextual message if you want.
defineObject{
name = "party",
baseObject = "party",
components = {
{
class = "Party",
onCastSpell =
function(party,champion,spellName)
local itmName = ""
local spellUiName = ""
if spellName == "water_breathing" then
itmName = "scroll_water_breathing"
spellUiName = "Water Breathing"
end
if spellName == "resurrection" then
itmName = "scroll_resurrection"
spellUiName = "Resurrection"
end
if spellName == "antidote" then
itmName = "scroll_antidote"
spellUiName = "Antidote"
end
if spellName == "recovery" then
itmName = "scroll_recovery"
spellUiName = "Recovery"
end
if spellName == "antivenom" then
itmName = "scroll_antivenom"
spellUiName = "Antivenom"
end
if spellName == "enchant_arrow" then
itmName = "scroll_enchant_arrow"
spellUiName = "Enchant Arrow"
end
if spellName == "heal" then
itmName = "scroll_heal"
spellUiName = "Healing"
end
if spellName == "mass_heal" then
itmName = "scroll_mass_heal"
spellUiName = "Mass Healing"
end
if spellName == "shield" then
itmName = "scroll_shield"
spellUiName = "Shield"
end
if spellName == "force_field" then
itmName = "scroll_force_field"
spellUiName = "Force Field"
end

itmName = "scroll_fireburst"
spellUiName = "Fireburst"
end
if spellName == "light" then
itmName = "scroll_light"
spellUiName = "Light"

itmName = "scroll_darkness"
spellUiName = "Darkness"
end

itmName = "scroll_darkbolt"
spellUiName = "Darkbolt"
end

itmName = "scroll_fireball"
spellUiName = "Fireball"
end

itmName = "scroll_meteor_storm"

end

itmName = "scroll_dispel"
spellUiName = "Dispel"
end
if spellName == "frostbolt" then
itmName = "scroll_frostbolt"
spellUiName = "Frostbolt"
end
if spellName == "fire_shield" then
itmName = "scroll_fire_shield"
spellUiName = "Fire Shield"
end
if spellName == "shock_shield" then
itmName = "scroll_shock_shield"
spellUiName = "Shock Shield"

This is cool. Just by any chance in case you will like this idea, here is link for LOG1 script , where you need to learn spell before casting it. I think it is working very similar way and it should be even quite better than just owning the script in the inventory. However it need to be converted into Log2 and my scripting knowledge is not so high :/ viewtopic.php?f=14&t=4629&hilit=learn+s ... g&start=10
defineObject{
name = "party",
baseObject = "party",
components = {
{
class = "Party",
onCastSpell =
function(party,champion,spellName)
local itemName = "scroll_"..spellName
for i = 1, 32, 1 do
if champion:getItem(i) ~= nil and champion:getItem(i).go.name == itemName then
return true
end
end
hudPrint(champion:getName().." needs to have the spellscroll on him to be able to cast it")
return false
end
}
}
Should do the same thing and it works for custom spells too. One of the base rules of programming is DRY "Don't repeat yourself". I know it's hard at first, but try to think that way

I used this method too, champ needs to own the scroll but also have sufficient skill to "use" the consumable scroll >> turns into a read scroll in inventory with all the spell info that was hiding otherwise.
I will convert this script over soon and post back here...

*there is a --icon ref for the learned scroll from akroma_icons1

I have only listed fireburst in the spell tables, you will need add spells as you go to spellbook and spellNames
I believe that the game engine automatically generates scrolls for spells without needing to script the spell scrolls. Perhaps because you have done this the scroll has listed it twice?

Should do the same thing and it works for custom spells too. One of the base rules of programming is DRY "Don't repeat yourself". I know it's hard at first, but try to think that way
so, if i already have some custom spells (Jhaelen's excellent healing spells) in my spell.lua, and i add this code in there as well, for any and all spells, players will need the scroll to cast them, custom ones too?
would that script return true if the spellscroll was in a container? The reason i ask, is i wonder if i could make a modified 'wooden box' or 'sack' as a spellbook for the scrolls Nevermind, the answer is no.
