Hideout component error


Recommended Posts

Using the hideout component I simply wanted to set a "OnGoHome" function.

    inst:AddComponent("hideout")
	inst.components.hideout:SetGoHomeFn(OnGoHome)

The function set doesn't run since I always get the error "scripts/components/hideout.lua"]:187: variable 'count' is not declared"

so I can link it back to the following from the component:

function Hideout:GoHome( child )
    if self.storedcreatures[child] ~= nil then
        print("Ack! We already have this child inside!?")
        return
    end

    self.storedcreatures[child] = child
    self.numstoredcreatures = GetTableSize(self.storedcreatures)

    child:RemoveFromScene()
    child.Transform:SetPosition(0,0,0)
    if child.components.brain then
        BrainManager:Hibernate(child)
    end
    if child.SoundEmitter then
        child.SoundEmitter:KillAllSounds()
    end

    if self.ongohome then
        self.ongohome(self.inst, count)
    end

    if self.numstoredcreatures == 1 and self.onoccupied then
        self:onoccupied(self.inst)
    end
end

But I'm still unsure what it is that I'm missing for it to run. I've tried guessing but have had no luck. I was wondering if it was even intended for "count" to be here. From what I can find only the cavelight prefab uses this component and doesn't use this gohome function either.

Any help is appreciated

You're right and this is a bug, please do report it in the bug tracker.

A workaround is to make your own hook and callback for it:

inst:AddComponent("hideout")

local GoHome_old = inst.components.hideout.GoHome

inst.components.hideout.GoHome = function(self, child, ...)
    local retval = GoHome_old(self, child, ...)
    -- Your code for "OnGoHome" event here
    return retval
end

You can make it call your other function if need be.

 

Reason for the three dots and return value is to help futureproof your hook in case Klei changes things around.

To solidify it futher is to put the return values from the _old function in a table and return an unpack function call, but I digress.
