Need help - function not doing anything

[Gabinours]

Hi guys !

I'm trying to make my first mod (which is a character) and I can't get my function to work :/

Game doesn't crash or anything, it's just as if I didn't write my function.

It's a perk that would give my character benefits when eating raw mushrooms, here's my code :

 

local function oneat(inst, food)    
    if food and food.prefab == "red_cap" then
           inst.components.health:DoDelta(30)
           inst.components.sanity:DoDelta(5) 
    elseif food and food.prefab == "green_cap" then
           inst.components.health:DoDelta(10) 
           inst.components.sanity:DoDelta(35) 
    elseif food and food.prefab == "blue_cap" then
           inst.components.health:DoDelta(10)
           inst.components.sanity:DoDelta(20) 
     end
end

 

I put this in my character prefab and I thought it would work but it doesn't, I'm probably just plain stupid and need to "activate" the function somewhere but I'm clueless, so a little help would be more than appreciated !  =)

put this inside master_postinit of YOURCHARACTER.lua 

inst:ListenForEvent("oneat", function(inst, data) 
if data.food.prefab == "red_cap" then
	inst.components.health:DoDelta(30)
    inst.components.sanity:DoDelta(5) 
elseif data.food.prefab == "green_cap" then
	inst.components.health:DoDelta(10) 
	inst.components.sanity:DoDelta(35) 
elseif data.food.prefab == "blue_cap" then
	inst.components.health:DoDelta(10)
	inst.components.sanity:DoDelta(20) 
end)

Hey ! Thanks for stopping by

SuperDavid ! 

When I pur your code inside the master_postinit, the game crashes when I launch the server, here's the log :

 

[string "scripts/mainfunctions.lua"]:119: Error loading file prefabs/walter
[string "../mods/Walter/scripts/prefabs/walter.lua"]:76: unexpected symbol near ')'
LUA ERROR stack traceback:
        =[C] in function 'assert'
        scripts/mainfunctions.lua(119,1)
        =(tail call) ?
        =[C] in function 'xpcall'

 

It refers to the " end)", the last line of your code, any idea how to fix this ?

Sorry I missed one "end", hahaha !

Spoiler

inst:ListenForEvent("oneat", function(inst, data) 
	if data.food.prefab == "red_cap" then
		inst.components.health:DoDelta(30)
		inst.components.sanity:DoDelta(5) 
	elseif data.food.prefab == "green_cap" then
		inst.components.health:DoDelta(10) 
		inst.components.sanity:DoDelta(35) 
	elseif data.food.prefab == "blue_cap" then
		inst.components.health:DoDelta(10)
		inst.components.sanity:DoDelta(20) 
	end
end)

Ahah no worries !  =)

It's working perfect now, thanks to you ! 

If you don't mind, I'd like it if you could explain why my version wasn't working, so that I don't make the same mistake again ^^ 

But that's totally ok if you don't, your work here is done ahah !

Thanks again !

Because you probably missed the "listen for event" in your master post init.

You have two ways to do it, usually. The way superdavid did it, a big function directly in the listed for event, or in two steps. For example, i have this in my character master post init :

    inst:ListenForEvent("killed", onkilled)

Then in a separate function (in the same file) i have :

local function onkilled(inst, data)
if data.victim:HasTag("animal") then
 inst.components.sanity:DoDelta(-TUNING.SANITY_SMALL)
 end
end

But the function itself will never works without the "listenforevent".

 

(Also, the data. part must be important too)
