Here is some code for an Immolation spell and chain lightning.
Invisibility spell has been removed to make room for the gesture for the chain lightning spell.

firering texture will have to be make for the immolation spell and immosound made and put into the sound folder of your dungeon
wav file 16 bit.

both spells work but no exp awarded to party which i am working on.
I have been trying to put an onDie hook in monster code to give exp on death but it does not work.

Hey LordGarth

Take some time to read through either -
AndakRainor's spellpack
viewtopic.php?f=22&t=9579
or minmays spells
viewtopic.php?f=22&t=9065
or Zimber's ....
viewtopic.php?f=22&t=14538

most of your questions should be answered

For "immolate", here is an alternate onCast(), that replaces the multiple IF conditions, centers spell on party if cast at a wall, and tags the spell for champion XP.

*Doesn't check for secret doors ~yet... (but will when I get back later tonight)

Thankyou

Will try

onCast = function(champion, x, y, direction, elevation, skillLevel)
local dX,dY = getForward(party.facing) --Directional offsets
if party.map:isWall(party.x+dX, party.y+dY, party.elevation) then
dX,dY = 0,0 --Targets Party's cell if cast on a wall
end
--spell cast and tagged for the champion who cast it.
spawn("immolate", party.level, party.x+dX, party.y+dY, party.facing, party.elevation).cloudspell:setCastByChampion(champion:getOrdinal())
end

This code works great thanks alot

onCast = function(champion, x, y, direction, elevation, skillLevel)
local dX,dY = getForward(party.facing) --Directional offsets
if party.map:isWall(party.x+dX, party.y+dY, party.elevation) then
dX,dY = 0,0 --Targets Party's cell if cast on a wall
end
--spell cast and tagged for the champion who cast it.
spawn("immolate", party.level, party.x+dX, party.y+dY, party.facing, party.elevation).cloudspell:setCastByChampion(champion:getOrdinal())
end

It does not work for launch spells that travel.
I get a cloudspell error. I tried replacing cloudspell with projectile and tried tiledamager and still wont work.
I tried putting an onHitMonster hook in the first and second object that the spell calls up and still no exp.

I will try to make code that will spawn the cloudspell in front of the party of course and 1 and 2 squares away so the spell will act like a flamethrower but will still be cloudspell and exp will be awarded.

It does not work for launch spells that travel.

It was intended to apply only to cloudspells cast by [directly in front of] the party. It can certainly be modified; or incorporated into a larger onCast(). As-is, it doesn't even use the skillLevel parameter.

Have a look inside poison_bolt.lua, in the asset pack.

excerpt [from "poison_bolt_greater_blast"]:

do you know how to make it work for launch spells.

Thanks,

LordGarth

There are numerous versions of this floating around, but this is what Im using atm for projectileSpells:
(currently lets you cast through grating - sparse doors - will update....)
Call it this way:
projectile = "projectile_name"
power = number
volleyCount = number
delay = number
sound = "sound_name"
cost = number (extra cost for each additional projectile in volley)

Isaac, this code was for cloud spells (allowing you cast through grating) ... do you have your version for projectiles (cant cast through grating) handy?
I can post mine, but Im pretty sure yours will be less messy!
(Ive just quickly added your^^ check to my script here to keep it simple)

we should really set up a definitive thread for these Spell basics
(we have all have posted this stuff so many times lol)

I do not have a version of that. [yet]
The cloudspell wall check was purpose built for this thread, after I read LordGarth's post.

*The poison_bolt spell won't cast past a door in the default game.
(Nothing can shoot the party through a door either; but the slimes can burn the adjacent party through a grate.)
