(sigh - why are some things THAT complicate... )
Sorry, minmay, doesn't work. Probably, I am doing something wrong.
Does your code mean a) I have to re-define my spell as a projectile b) I have to use your code on an CastSpellComponent? I tried it still in an ItemActionComponent (of course in an onAttack hook).
Ask a simple question, get a simple answer
Re: Ask a simple question, get a simple answer
Hey THOM,
minmays projectile script is good, I have based mine on that script and have no dramas at all.
I can try and step you through it
First! - paste this into a script entity (dungeon or external) - name it "projectileScripts"
Next! - define your spell - which you already have done
(here is simple projectile spell thats was on hand - someone elses spell actually)
- just paste this into whatever script you import for your spells (or not)
And here is a Weapon that will fire the spell (secondary action)
Note** projectileScripts has been running smoothly for a year or two now... its very easy!
And I have built in functionality for volleys of projectile spells .... you just need to assign numbers to volleyCount, & delay, (eg, 5, 0.5 - 5 projectiles, delay of 0.5s)
You just call it like this:
Hope this helps!

Re: Ask a simple question, get a simple answer
It is just a demonstration of how to spawn a projectile in the same place it would be created by the builtin Fireball/Frostbolt/Lightning Bolt/Poison Bolt spells. You would use it wherever you want to launch a projectile. A plain ItemComponent's onAttack hook will work, so will anywhere else, you just need to supply the champion, x, y, direction, and elevation. You don't need to define a new spell or use a ScriptComponent unless you want to.THOM wrote:(sigh - why are some things THAT complicate... )

}Re: Ask a simple question, get a simple answer
You are the one who exchanged function declarations "just because". You took the declaration for an onCastSpell hook function, and pasted it as the declaration for an ItemActionComponent.onAttack hook function. These hooks receive different arguments, so using the same declaration is unlikely to make semantic sense, and in fact the two hooks don't even receive the same number of arguments.
Anyway, now the problem is that you just moved the onAttack field from the ItemActionComponent to the ItemComponent. Move it back to the ItemActionComponent.
