Need teacher for this DragDrop combine item experiment

10-17-2006, 03:19 PM

ok basically, drag and drop one item onto another, and create another new item, I've look into InvX and try to learn something from it and did a small experimet
Result : failed (if sucessed i wont be asking here =.=")

First, the setup for the recipe

JASS:

function Item_Combo takes integer item1id, integer item2id, integer resultid returns nothing
 local string k1=I2S(item1id)
 local string k2=I2S(item2id)
    call StoreInteger(udg_gc,k1,"com"+k2,resultid)
    call StoreInteger(udg_gc,k2,"com"+k1,resultid)
endfunction

function SetupInventorySystem takes nothing returns nothing
//item combo
//the list get longer and longer and so on
    call Item_Combo('rat6','rat9','ratc')
    call Item_Combo('dada','dede','boom') // just an example
    call Item_Combo('dudu','didi','baam') // just an example
endfunction
//===========================================================================
function InitTrig_Setup_Inventory_System takes nothing returns nothing
    call ExecuteFunc("SetupInventorySystem")
endfunction

then, for the dragdrop and combine itself

JASS:

function DragDrop takes nothing returns nothing
 local gamecache g = udg_gc
 local integer i = GetIssuedOrderId()
 local unit u = GetTriggerUnit() //-----------------Triggering unit
 local item x = UnitItemInSlot(u,i-852002) //-------transfering item
 local item y = GetOrderTargetItem() //-------------targeted item
 local integer sloty = i-852002
 local integer ix = GetItemTypeId(x)
 local integer iy = GetItemTypeId(y)
 local string sx = I2S(ix)
 local string sy = I2S(iy)
 local integer result
    if HaveStoredInteger(g,sx,"com"+sy) then
        set result = GetStoredInteger(g,sx,"com"+sy)
        call RemoveItem(x)
        call RemoveItem(y)
        call UnitAddItemToSlotById(u,result,sloty)
    endif
 set g=null
 set u=null
 set x=null
 set y=null
 set sx=null
 set sy=null
endfunction

//===========================================================================
function InitTrig_Inventory_Item_Combine takes nothing returns nothing
 local trigger t = CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ( t, EVENT_PLAYER_UNIT_ISSUED_TARGET_ORDER )
    call TriggerAddAction( t, function DragDrop )
 set t = null
endfunction

p/s the game shows no error during saving, just not working

Vexorian	currently seems the problem lies with the gc variable, maybe it is not initialized correctly

zen87	hmmm it seems so, maybe global game cache wont work for this ? because i just extract and modift the triggers... so what should i do ? someting like this ? (go test again... =\|) JASS: call InitGameCacheBJ( "CombineSystem.w3v" ) set udg_gc = GetLastCreatedGameCacheBJ()

Vexorian	maybe that is getting initialized after the InitTrig_Setup_Inventory_System is called. Could depend on random World Editor decisions, but if you are initializing it in a trigger with a map initialization event then it surelly would be initialized in the wrong time

zen87	ah yeah, guess my problem is temporary solved, i moved my main game cache intialisation to this trigger and it seems that things are going fine for now (temporary... =.=) so teacher, is there anyway to make sure the game cache get initialised FIRST before running other initalisation triggers ?

Vexorian	As a matter of fact, there is. There are 2 ways one involves some oscure methods to make sure a trigger is compiled first and the other one involves my preprocessor and the //! library command
