Upgrading Same Weapon Item

 

[Pyrogasm]

It would be easiest with a 2D array:

• Events
  • Time - Elapsed game time is 0.50 seconds
• Conditions
• Actions
  • Custom script: set udg_NO_ITEM_TYPE = 0 //This line doesn't need to be done, just here for completeness; you need to create an item type variable called NO_ITEM_TYPE and simply don't assign it a default value (it's used in comparisons below)
  • Set MAX_ITEM_COMBINES = 4 //greater than or equal to the maximum number of times any item in the map can be upgraded
  • Set MAX_ITEM_COMBINES = MAX_ITEM_COMBINES + 1 //so it works properly it needs to be one greater
  • -------- --------
  • Set ItemNum = ItemNum + MAX_ITEM_COMBINES
  • Set CombineItem[ItemNum + 0] = Rocket Cannon (Dummy Buy)
  • Set CombineItem[ItemNum + 1] = Rocket Cannon
  • Set CombineItem[ItemNum + 2] = Double Rocket Cannon
  • Set CombineItem[ItemNum + 3] = Triple Rocket Cannon
  • Set CombineItem[ItemNum + 4] = Quad Rocket Cannon
  • -------- --------
  • Set ItemNum = ItemNum + MAX_ITEM_COMBINES
  • Set CombineItem[ItemNum + 0] = Arrow Launcher (Dummy Buy)
  • Set CombineItem[ItemNum + 1] = Arrow Launcher
  • Set CombineItem[ItemNum + 2] = Double Arrow Launcher
  • Set CombineItem[ItemNum + 3] = Triple Arrow Launcher
  • Set CombineItem[ItemNum + 4] = Quad Arrow Launcher
  • -------- --------
  • Set ItemNum = ItemNum + MAX_ITEM_COMBINES
  • Set CombineItem[ItemNum + 0] = Regular Gun (Dummy Buy)
  • Set CombineItem[ItemNum + 1] = Regular Gun
  • Set CombineItem[ItemNum + 2] = Really Fucking Big Gun That Doesn't Upgrade
  • -------- --------
  • etc.
  • -------- --------
  • Set NUM_BASE_COMBINES = ItemNum / MAX_ITEM_COMBINES

• Events
  • Unit - A unit acquires an item
• Conditions
• Actions
  • Set B_Item = (Item being manipulated)
  • Set B_IType = (Item-type of B_Item)
  • Set B_Unit = (Triggering Unit)
  • For each Integer BaseInt from 1 to NUM_BASE_COMBINES) do (Actions)
    • Loop - Actions
      • Set ItemNum = BaseInt x MAX_ITEM_COMBINES
      • If (All conditions are true) then do (Then actions) else do (Else actions)
        • If - Conditions
          • B_IType equal to CombineItem[ItemNum]
        • Then - Actions
          • Set GiveItem = CombineItem[ItemNum]
          • Set FoundItem = False
          • For each Integer SlotInt from 1 to 6 do (Actions)
            • Loop - Actions
              • Set S_Item = (Item carried by B_Unit in slot SlotInt)
              • Set S_IType = (Item-type of S_Item)
              • For each Integer CombInt from ItemNum to (ItemNum + (MAX_ITEM_COMBINES - 1)) do (Actions) //the -1 is because the max rank can't be upgraded
                • Loop - Actions
                  • If (All conditions are true) then do (Then actions) else do (Else actions)
                    • If - Conditions
                      • S_IType equal to CombineItem[CombInt]
                      • CombineItem[(CombInt + 1)] not equal to NO_ITEM_TYPE
                    • Then - Actions
                      • Set FoundItem = True
                      • Item - Remove S_Item
                      • Set GiveItem = CombineItem[(CombInt + 1)]
                      • Custom script: exitwhen true
                    • Else - Actions
          • If (All conditions are true) then do (Then actions) else do (Else actions)
            • If - Conditions
              • FoundItem equal to True
            • Then - Actions
              • Custom script: exitwhen true
            • Else - Actions
        • Else - Actions
  • Hero - Create GiveItem and give it to B_Unit
  • Set GiveItem = NO_ITEM_TYPE

I did not make a map. I just wrote that in the forum reply box; you will have to recreate it yourself. Honestly it will be a good exercise and perhaps you will better understand how the trigger works in the process.

Just look at how it's used... If it doesn't have a [] after it it's not an array. What kind of variable they are should be obvious from how they are used.
