Custom crockpot help

[MrDoge124]

I've been trying to makea custom crock pot.
It's all working until I press the cook button.
The error is in this part of the code, near the RPC.DoWidgetButtonAction part.

413: attempt to index global 'RPC' (a nil value)

This is the code

function params.m_portablecookpot.widget.buttoninfo.fn(inst, doer)
    if inst.components.container ~= nil then
        BufferedAction(doer, inst, ACTIONS.COOK):Do()
    elseif inst.replica.container ~= nil and not inst.replica.container:IsBusy() then
        SendModRPCToServer(RPC.DoWidgetButtonAction, ACTIONS.COOK.code, inst, ACTIONS.COOK.mod_name)
    end
end

Thanks for taking the time to read this.

    end
end

As the error already tells you, RPC is not defined. As you are in the modmain, you need to add a GLOBAL before it to use the correct environement.

If you haven't declared 

local ACTIONS = GLOBAL.ACTIONS

beforehand, you will also need to add a GLOBAL before ACTIONS

[MrDoge124]

I tried adding GLOBAL. onto RPC and it got another error.

Not quite sure what's going on.

How would I declare a RPC?

[Monti18]

Ah I didn't see that you were using the SendModRPCToServer. Change it to

GLOBAL.SendRPCToServer

as the mod RPC is defined differently.

[MrDoge124]

 It started cooking but for some reason crashed
This is the error it put out.

It seems to be having issues in the stewer.lua component.

[Monti18]

You probably didn't add the recipes to your crock pot, that's why it's looking at an empty list and can't return anything.

I think you can do it with:

local foods = require("preparedfoods")
for k,recipe in pairs (foods) do
	AddCookerRecipe("your_crock_pot_prefab", recipe) 
end

 

[MrDoge124]

It seems to cook the food without crashing now. However the food is invisible.
I've tried multiple recipes and they're all doing this.

[Monti18]

What does the prefab file of your cookpot look like?

Did you add a code snippet like this one?

local function SetProductSymbol(inst, product, overridebuild)
    local recipe = cooking.GetRecipe(inst.prefab, product)
    local potlevel = recipe ~= nil and recipe.potlevel or nil
    local build = (recipe ~= nil and recipe.overridebuild) or overridebuild or "cook_pot_food"
    local overridesymbol = (recipe ~= nil and recipe.overridesymbolname) or product

    if potlevel == "high" then
        inst.AnimState:Show("swap_high")
        inst.AnimState:Hide("swap_mid")
        inst.AnimState:Hide("swap_low")
    elseif potlevel == "low" then
        inst.AnimState:Hide("swap_high")
        inst.AnimState:Hide("swap_mid")
        inst.AnimState:Show("swap_low")
    else
        inst.AnimState:Hide("swap_high")
        inst.AnimState:Show("swap_mid")
        inst.AnimState:Hide("swap_low")
    end

    inst.AnimState:OverrideSymbol("swap_cooked", build, overridesymbol)
end

local function spoilfn(inst)
    if not inst:HasTag("burnt") then
        inst.components.stewer.product = inst.components.stewer.spoiledproduct
        SetProductSymbol(inst, inst.components.stewer.product)
    end
end

local function ShowProduct(inst)
    if not inst:HasTag("burnt") then
        local product = inst.components.stewer.product
        SetProductSymbol(inst, product, IsModCookingProduct(inst.prefab, product) and product or nil)
    end
end

This is from cookpot.lua, I think this one makes the cookpot show the product.

[MrDoge124]

Yes I do have this code in the file, I'm using the portable crock pot as a base. The code was already there and I haven't done anything to it.
This is what mine looks like right now.

local function SetProductSymbol(inst, product, overridebuild)
    local recipe = cooking.GetRecipe(inst.prefab, product)
    local potlevel = recipe ~= nil and recipe.potlevel or nil
    local build = (recipe ~= nil and recipe.overridebuild) or overridebuild or "cook_pot_food"
    local overridesymbol = (recipe ~= nil and recipe.overridesymbolname) or product

    if potlevel == "high" then
        inst.AnimState:Show("swap_high")
        inst.AnimState:Hide("swap_mid")
        inst.AnimState:Hide("swap_low")
    elseif potlevel == "low" then
        inst.AnimState:Hide("swap_high")
        inst.AnimState:Hide("swap_mid")
        inst.AnimState:Show("swap_low")
    else
        inst.AnimState:Hide("swap_high")
        inst.AnimState:Show("swap_mid")
        inst.AnimState:Hide("swap_low")
    end

    inst.AnimState:OverrideSymbol("swap_cooked", build, overridesymbol)
end

local function spoilfn(inst)
    if not inst:HasTag("burnt") then
        inst.components.stewer.product = inst.components.stewer.spoiledproduct
        SetProductSymbol(inst, inst.components.stewer.product)
    end
end

local function ShowProduct(inst)
    if not inst:HasTag("burnt") then
        local product = inst.components.stewer.product
        SetProductSymbol(inst, product, IsModCookingProduct(inst.prefab, product) and product or nil)
    end
end

 

Thanks for you help so far!

[Monti18]

You're welcome!

When you cook a food in the cookpot, have a look at what the client log or the server log tells you. It should probably show something.

Try to compare your mod with other mods that add custom cookpots, for example the warly mod from before warly was added to don't starve together.

[MrDoge124]

Right I had a look in the log and it said "Could not find anim build ratatouille" Which could be an issue.
If I find anymore things in the log I'll add them here.

[Monti18]

Try changing this:

local function ShowProduct(inst)
    if not inst:HasTag("burnt") then
        local product = inst.components.stewer.product
        SetProductSymbol(inst, product, IsModCookingProduct(inst.prefab, product) and product or nil)
    end
end

to this:

local function ShowProduct(inst)
    if not inst:HasTag("burnt") then
        local product = inst.components.stewer.product
        SetProductSymbol(inst, product)
    end
end

It seems like it sets the build as the product name instead of cook_pot_food, so this should make it use cook_pot_food.

[MrDoge124]

It's showing up in the crockpot now, this should mean it's all good now.

Thanks for helping!
