[Macix]

Dodałem do swojej mapy możliwość kupna psa. Tutaj wszystko działa. Kupuje psa u handlarza zwierzętami, on sobie chodzi po farmie, ale trzeba go karmić suchą karmą, którą trzeba kupić w sklepie. 
Więc  skopiowałem z innej mapy wszystkie linijki które według mnie mają coś wspólnego z dodaniem tego do mapy. 

Do folderu ze skryptami skopiowałem:
- addStoreCategory.lua ( z tego co zrozumiałem to on dodaje nową kategorię do sklepu )
- regFillTypes.lua ( a ten dodaje do mapy filltype tej suchej karmy )

Oczywiście skrypty podpiołem w pliku modDesc.
<sourceFile filename="scripts/regFillTypes.lua"/>
<sourceFile filename="scripts/addStoreCategory.lua"/>

Stworzyłem też folder store a do niego skopiowałem miniaturkę tej suchej karmy w sklepie i miniaturkę tej nowej kategori w sklepie. 

W hud/filltypes dodałem hudy tej suchej karmy.
W maps/objects/pallets jest plik i3d tej suchej karmy i inne pliki takie jak:
- bag_normal.dds
- bag_specular.dds
- dogFeed.i3d
- dogFeed.i3d.shapes
- dogFeed.xml
- dogFeedBag_diffuse

Tak wygląda ten plik dogFeed.i3d

    <size width="0.6" length="1" /> 
</object>

Do pliku modDesc skopiowałem:

<regFillTypes hudDirectoryFillTypes="hud/fillTypes" textureDirectoryFillPlanes="fillPlanes">
<fillType name="dogFeed"
categoryName="piece"
pricePerLiter="1.0"
massPerLiter="0.000001"

createHeap="false" 
useToSpray="false" />   
</regFillTypes>

<storeItems>
<newCategories><newCategory name="mapAdditionals" previousCategory="tractors" imageFilename="store/category_mapAdditionals.dds" /> </newCategories>
<storeItem xmlFilename="maps/objects/pallets/dogFeed.xml"/>
</storeItems>

<!-- Shop Items / Vehicles -->
<text name="mapAdditionals"> <en>Map Additionals</en> </text>
<text name="function_dogFeed"> <en>dry food in a bag, is needed as basic food for your farm dog.</en> <pl>Sucha karma w opakowaniu, jest wymagana jako podstawowe jedzenie dla psa na farmie.</pl> </text>
<text name="shopItem_dogFeed"> <en>dry food</en> <pl>Sucha karma</pl> </text>

<text name="dogFeed"> <en>dry fodder</en> <pl>Sucha karma</pl> </text>

I chyba wszystko działa, bo ta nowa kategoria pojawia się w sklepie, a w niej pojawia się ta sucha karma. Ale gdy chce ją kupić to nie pojawia się przed sklepem.
