[Solved]Custom component is null

[Nelzanger]

Hello,

I'm trying to make a gauge mechanic for my custom character when equipping a hat.  After checking how some components works (like health, moisture or hunger), I've decided to make a simple custom component, placed in the "components" folder of my mod, to check if it has been correctly added. Its content is shown below :

--hateffect.lua
local Hateffect = Class(function(self, inst)
    self.inst = inst
    self.maxEffect = 100
    self.minEffect = 0
    self.current = 50
end)

return Hateffect

 

However, when I use inst:AddComponent("hateffect") in the function to make my hat prefab, trying to access it afterwards tells me that inst.hateffect is null.

I thought it might be a initialization issue, so I also tried add the component when equipping the hat, with the code below, while still having the component added in the prefab function :

-- MyHat:OnEquip(inst, owner)
inst:AddComponent("hateffect")
    
if (inst.hateffect == nil) then
      print("ERROR : THE HAT COMPONENT IS STILL NULL")
else
      print("THE HAT COMPONENT HAS BEEN ADDED !")
end

But I got the following logs, that tell me my custom component already exists, but when tested with the code above, says it's still null :

[00:00:37]: Registering master server in EU lobby
[00:00:45]: Resuming user: session/0D653EA1B3E0311F/A7JL7RU4BBIS/0000000260

[00:01:03]: component hateffect already exists on entity 118107 - damage_hat(LIMBO)!
[00:01:03]: ERROR : THE HAT COMPONENT IS STILL NULL	

Important note : Disabling the addComponent in the prefab function, and letting the code in the OnEquip didn't work either, the component stays null.

I've checked other mods' scripts to see how custom components are added, but so far, it seems that everything is managed in modutils.lua when creating a new custom component, and that calling your custom component in inst:AddComponent is enough.

So what did I miss here ? Why my component is still null when I'm trying to use it, but the log tells me that it already exists ?

Nevermind When adding a component, a correct call is to access the components table like this.

inst.components.hateffect

I must be tired.
