Fishguts : ToDo List 20090912

A rough todo list;

* Re-work the “work flow” for shops
* Selling Items
* Make Inventory screen non-static, make it selectable with “Use” action
* Do Oracle / Pub code (The “How much do you offer...” code)
* Peer at Gem
* Wandering monsters (The code is already there with the shopkeepers). Really need to add a couple onto the maps and see how they behave.
* Training Halls for leveling up

The last big stint after all these small things will be the combat code, roughly;

* Quick Targeting of monsters as well as arbitrary targeting
* Melee + Ranged combat
* Magic

Shop code has turned into a small nightmare. There are lots of things that are closely related but not, and requires slightly different implementations.

I have the following kind of shops
* Food / Weapons / Armour / etc (the standard shop type)
* Oracle / Pub The “How much do you pay/offer” type deal.
* Training Hall

I have had to write a common ‘widget’ that is shared, which is the pick list / item list. Talking to NPC requires a scrolling list of keywords, shops require a scrolling list of items, etc.

I am thinking of changing my design for the oracle + pub type deal.

Initially it was going to be you offer X$ and get a response back. Now I think for oracles I’ll have different things like

== Marvin the Mystic ===
Select your desire
    10$ Palm Reading 
    50$ Aura Reading
   100$ Tea Leaf reading
   500$ Tarot Cards
  1000$ Bones

And variations on the theme, which gets the pick list reused again.

If I wanted to go ‘ugly’ I could re-use the framework for Talking as its fairly arbitrary and very easy to re-use, thus any ‘new’ shop could be done instantly.

Below is pretty rough but should be close to compiling I think. The only downside right now is there is no ‘multiple’s so you can only buy a qty of 1 each time, but that could be rectified by a change to the talk code to add a quantity field to the data… Then where qrt is > 1, the user could be prompted for how many to buy… that would work.

   1:-- Creating Buy/Sell from talk code
   2:function InitShopScreen(tblItems)
   3:    ClearTalkList()
   4:
   5:    local key,val
   6:    for key,val in pairs(tblItems) do
   7:        AddToTalkList(val)
   8:    end
   9:end
  10:
  11:function DoShopBuy()
  12:    InitShopScreen({"KNIFE", "AXE"})
  13:    
  14:    local id, kw
  15:    id = 0
  16:    while id ~= -1
  17:        id, kw = GetTalkInput()
  18:        
  19:        if id ~= -1 then
  20:            id = GetItemIndexFromName(kw)
  21:            if GetPlayerGold() >= GetItemCost(id) then
  22:                AddToInventory(id)
  23:                SetPlayerGold( GetPlayerGold() - GetItemCost(id) )
  24:                MsgBox("YOU BOUGHT : " .. GetItemName(id), " OK ", "")
  25:            else
  26:                MsgBox("YOU DONT HAVE ENOUGH CASH!", " OK ", "")
  27:            end
  28:        end
  29:    end
  30:end
  31:
  32:function DoShopSell()
  33:    local i, id, kw
  34:    
  35:    id = 0
  36:    while id ~= -1
  37:        ClearTalkList()
  38:    
  39:        for i=1..G_MAX_INVENTORY_ITEMS do
  40:            local idx
  41:            
  42:            idx = GetInvnetoryItemIndex(i)
  43:            
  44:            if idx ~= -1 then
  45:                AddToTalkList( GetItemName(idx) )
  46:            end
  47:        end
  48:        
  49:        id, kw = GetTalkInput()
  50:        if id ~= -1 then
  51:            RemoveFromInventory(id)
  52:            
  53:            id = GetItemIndexFromName(id)
  54:            SetPlayerGold( GetPlayerGold() + (GetItemCost(id)/2) )
  55:            
  56:            MsgBox("SOLD FOR " .. GetItemCost(id)/2, " OK ", "")
  57:        end
  58:    end
  59:end
  60:
  61:function DoShop()
  62:    local id, kw
  63:    
  64:    id = 0
  65:    while id ~= -1
  66:        InitShopScreen( { "BUY", "SELL" })
  67:        
  68:        id, kw = GetTalkInput()
  69:        if kw == "BUY" then DoShopBuy() end
  70:        elseif kw == "SELL" then DoShopSell() end
  71:    end
  72:end

Going to have to rethink this train of thought. I’m kinda liking the idea of reusing my talk code and cutting out all the other special shop code.... Might have to branch my code and see how implementation goes.
