Help with prefab check.

[noobitomignon]

Hi, I'm fairly new to modding and LUA in general and I'm having a problem checking for a prefab in inventory.lua.

I wanna customise the boatwidget depending on what type of boat is mounted.

So there's this line

 

if self.boatwidget then

   self.boatwidget:SetPosition(whatever)

end

 

I wanna add a check for what prefab is used to create boatwidget. Like so

 

if self.boatwidget and self.boatwidget.prefab = "armouredboat" then

   self.boatwidget:SetPosition(whatever)

end

 

But it crashes and I'm lost

 

Any help is appreciated as I'm a noobie. Thanks

you didn't posted your error, but let me turn on my Vanga mode and say:

i guess it's here, this one is not exist

self.boatwidget.prefab 

why do you think that interface element have prefab too?

@Rincevvind That's the error I get : prefab is a nil value. What I want is check what kind of boat prefab is used to create the widget. I'm guessing it's really easy but since I have 0 knowledge of programming, I don't know how to achieve that

Or rather what boat prefab is used to create the container displayed in boatwidget.

I'm working on that exact thing. It's better to do it from modmain.lua like so

local function BoatBadgeFix(self)     local oldOpen = self.Open        function self:Open(container, doer, boatwidget)         oldOpen(self, container, doer, boatwidget)         local boatwidget_pos = self:GetPosition()         if self.container == GLOBAL.GetPlayer().components.driver.vehicle then             if container.prefab == "cargoboat" then                self:SetPosition(boatwidget_pos.x + your_x_value1, boatwidget_pos.y1 + your_y_value, 0)            elseif container.prefab == "armouredboat" or container.prefab == "rowboat" then                self:SetPosition(boatwidget_pos.x + your_x_value2, boatwidget_pos.y2 + your_y_value, 0)            elseif container.prefab == "lograft" or container.prefab == "raft" then                self:SetPosition(boatwidget_pos.x + your_x_value3, boatwidget_pos.y3 + your_y_value, 0)            end        end    endend AddClassPostConstruct("widgets/containerwidget", BoatBadgeFix)

Cargoboat is the one with slots.

Armouredboat and rowboat only have equip slots.

Raft and lograft don't have any slots.

 

You have to change "your_x_value" and "your_y_value" fof each one.

 

This line is to avoid modifying the widget's position when you're not on the boat

if self.container == GLOBAL.GetPlayer().components.driver.vehicle then

It works Thanks a lot @kiopho and thanks Rincevvind for giving it a shot
