Scripting Help for "3 Item Menu"

[David Ward]

Hello. I'm looking for some scripting help. There is a very specific script that I am trying to create but it is proving to be more difficult than I had first considered. I would be willing to trade services using the editor for some assistance in this regard.

The intention of the script is as follows.

There are 3 altars. There is 1 item on each altar, a prize, for completing a dungeon. Off to the side is an exit teleporter with an iron gate. The gate is open. If the player takes 1 item, the gate remains open. If the player takes 2 or more items, the gate closes. If the player puts the items back, so that only 1 item has been removed from the altar, the gate opens.

I cannot for the life of me figure out how to make this work. Any help would be muchly appreciated. Am willing to trade time for editor work (dungeon/map making, etc.). Thank you.

I've managed to figure this out, but the script code looks hilarious:

Code: Select all

function surfaceContains3(surface, item)
	for v,i in surface:contents() do
	if i.go.name == item then return true
	end
end
end


function deactivatebridge1()
	if surfaceContains3(altart11.surface, "long_sword") then
	magicbridget11.controller:deactivate()
	end
	
	if surfaceContains3(altart22.surface, "frostbite_necklace") then
	magicbridget11.controller:deactivate()
	end

	if surfaceContains3(altart33.surface, "full_helmet") then	
	magicbridget11.controller:deactivate()
	end

	if surfaceContains3(altart11.surface, "long_sword") and
	surfaceContains3(altart22.surface, "frostbite_necklace") and
	surfaceContains3(altart33.surface, "full_helmet") then
	
	magicbridget11.controller:activate()
	
	end
	
	if surfaceContains3(altart11.surface, "long_sword") and
	surfaceContains3(altart22.surface, "frostbite_necklace") then
	
	magicbridget11.controller:activate()
		
	end
	
	if surfaceContains3(altart11.surface, "long_sword") and
	surfaceContains3(altart33.surface, "full_helmet") then

	magicbridget11.controller:activate()	
		
	end
	
	if surfaceContains3(altart22.surface, "frostbite_necklace") and
	surfaceContains3(altart33.surface, "full_helmet") then

	magicbridget11.controller:activate()	
	
	end
	
end

Basically, If more than 1 of the 3 altar items is taken off their altars, the magic bridge leading to the exit deactivates. It reactivates until at least 2 items are on their altars (and the party has only then taken 1). I'm just glad it works.

Here is an alternate method. This script doesn't care where the prizes are, only that at least two of them are on the alcoves.
[If placement is important, it will need to be modified.]

To try it: Add the script, and connect a set of three alcoves to it; their names must end in sequence [_1,_2,_3]. The name prefix used in the script is 'dungeon_alcove'. Change if needed; it should match the prefix of your alcoves. The script uses mine_door_spear_1 by default; change the name in the doorOpen function() to match your chosen door.

Connect each alcove to the script twice; once for insert, and once for removal. Change the string item IDs in the 'prizes' table to match your own.

Code: Select all

prizes = {"figure_skeleton", "figure_ice_guardian", "figure_ogre"}

function _itemCheck()
	local tally = 0
	for x = 1, 3 do
		for _,item in findEntity("dungeon_alcove_"..x).surface:contents() do
			if item ~= nil then
				for i,prize in pairs(prizes) do
					if item.go.name == prize then
						tally = tally + 1
						break
					end
				end
			end
		end	
	end
	return tally >1
end

function doorOpen()
	if _itemCheck() then
		mine_door_spear_1.door:open()
	else mine_door_spear_1.door:close()	
	end
end

Okay see, that's awesome. Thank you very much for the reply. I do not at all know the depth of what you have put together there in the code, but I will give it a shot and report back.

[David Ward]

Followed your directions --> works perfectly. Thank you very kindly for writing that code and posting a reply to my inquiry. You are a gentleman and a scholar.

Hi Isaac. I know it's been awhile. I was wondering if there was a way to modify this "choose your 1 prize out of 3" system to make it, say, "2 out of 4". Is there a way to do that? To have 4 alcoves with 1 prize in each, and if more than 2 are taken, then the door shuts until there are at least 2 items still on the alcoves.

[Isaac]

Set the number of alcoves, and the number of gifts; in this case, 4 and 2.
*Remember the naming scheme for the alcoves.

Code: Select all

    prizes = {"figure_skeleton", "figure_ice_guardian", "figure_ogre", "figure_crowern"}
	alcoves = 4  
	gifts = 2
	
    function _itemCheck()
       local tally = 0
       for x = 1, alcoves do
          for _,item in findEntity("dungeon_alcove_"..x).surface:contents() do
             if item ~= nil then
                for i,prize in pairs(prizes) do
                   if item.go.name == prize then
                      tally = tally + 1
                      break
                   end
                end
             end
          end   
       end
       return tally >= alcoves - gifts
    end

    function doorOpen()
       if _itemCheck() then
          mine_door_spear_1.door:open()
       else mine_door_spear_1.door:close()   
       end
    end

Well then....that is service, sir. I did not expect such a quick response. The code works perfectly. You've thoroughly earned a mention in our game credits. Much obliged.
