Module:Item spawns

This module spits out the containers that specific item can spawn in, including chances. Does not show other special spawns or ground spawns.

Parameters

Must always call the main function. The second argument must be the exact name of an item.

Example

{{#invoke:Item spawns|main|Pure Veltecite}}

local p = {} --p stands for package

p.items = mw.loadJsonData( "User:VeryGreatFrog/sandbox2" )
p.lootPools = mw.loadJsonData( "User:VeryGreatFrog/sandbox3" )
p.containers = mw.loadJsonData( "User:VeryGreatFrog/sandbox4" )

local args = mw.getCurrentFrame().args

for k, v in pairs(p.items) do
    if args[1] == v["inGameName"] then
        p.item = k
        break
    end
end

function p.main( frame )
	local output =  p.items[p.item]["inGameName"] .. "<br>"
	for container, pools in pairs(p.containers) do
		for _, pool in ipairs(pools) do
			local curPools = p.lootPools[pool]
			if curPools then
				-- check if this item (the key) is in the spawns
				if curPools["items"][p.item] ~= nil then
					output = output .. container .. " Tier " .. curPools["tier"]  .. ": " .. tostring(round(curPools["items"][p.item]["chance"] / curPools["items"][p.item]["amount"], 2)) .. "% <br>"
				end
			end
		end
	end
	return tostring (output) 
end
