How to make custom dialogue on spell cast

[lordfool]

I have a sword with the spell teleport I want to make it so that on casting the spell on the mobs to say a phrase like "begone". How to do? And is it possible for me to make it so that each spell cast, a few points of hunger is reduced?

[Blueberrys]

@lordfool

 

Call this to make your character say something:

local cry = "begone"local duration = 2-- Where inst is the player instanceinst.components.talker:Say{Line(cry, duration)}

-

 

Can call this to reduce hunger

local hunger_cost = 5-- where inst is the player instanceinst.components.hunger:DoDelta(hunger_cost)

-

 

Do them both when you cast the spell, probably using OnAttack or OnCast or something of the sort.

I cant seem to get it to work, I dont know if I put it in the right place. Heres my weapon lua

Wait, why is this in weapons.lua? Aren't you making a custom item? Or did you want to modify an existing staff?

Either way, you shouldn't modify weapons.lua directly, you should use AddPrefabPostInit.

[lordfool]

Ah, by weapon lua I meant the custom item I wanted my character mod to have, this is the kantana.lua which is in my character mod in the prefabs folder.

 

katana.lua

[Blueberrys]

@lordfool Are you sure teleport_thread is being called? Put a print statement in there close to the other code, see if it's executing when you cast the spell.

[lordfool]

@Blueberrys,

Yea it gives me a

[00:00:45]: 110622 - katana(LIMBO)

[00:00:45]: 110622 - katana(LIMBO) 110011 - doge 110011 - doge     when I cast the spell.

If I leave the code as is it shows me this error.

@lordfool Hmm. I'm assuming the inst variable isn't referring to the player. Try placing the code elsewhere, or figure out what inst is referring to. Alternately, you can use GetPlayer() instead of inst. It's not very clean, but it'll do for now if you can't find another way.
