[Function] Functions useful in quests

[Seminari]

With functions: setPlayerMissionStatus and getPlayerMissionStatus you can easier make quests and you will be easier and faster to correct mistakes.
For example:
you made quest, but you gave the wrong order of storage values (example: in 6 mission script checks player_storage == 1, (but correct is storage == 2) then u will must change with all quest scripts after 6 mission to good values xD, with my functions u can make:
monday ninth mission
friday third mission
sunday eighth mission



1. add to folder data/LIB quests.lua, then add to quests.lua this table:

LIB_QUESTS_TBL = {
		["yalahar quest"] = {
							["third mission"] = {stg = 2222, start_value = 15, end_value = 17},
							["final battle"] = {stg = 2222, start_value = 39, end_value = 42},
							},
		["inquistion quest"] = {
							["first mission"] = {stg = 2222, start_value = 0, end_value = 6},
							["eclipse"] = {stg = 2222, start_value = 7, end_value = 9},
							["vampire hunter"] = {stg = 2222, start_value = 10, end_value = 15},
							},
					}

Now go to lib to file functions and add:

function setPlayerMissionStatus(cid, quest_name, mission_name, value)
	for a,b in pairs(LIB_QUESTS_TBL) do
		if a == quest_name then
			for c,d in pairs(b) do
				if c == mission_name then
					return setPlayerStorageValue(cid, d.stg, d.start_value + value)
				else
					return print("cannot find mission called ".. mission_name .." in quest ".. quest_name ..".")
				end
			end
		else
			return print("cannot find quest called".. quest_name .." in LIB_QUESTS_TBL.")
		end
	end
end

function getPlayerMissionStatus(cid, quest_name, mission_name)
	for a,b in pairs(LIB_QUESTS_TBL) do
		if a == quest_name then
			for c,d in pairs(b) do
				if c == mission_name then
					if getPlayerStorageValue(cid, d.stg) < d.start_value then
						return -1
					elseif getPlayerStorageValue(cid, d.stg) <= d.end_value then
						return (getPlayerStorageValue(cid, d.stg) - d.start_value)
					elseif getPlayerStorageValue(cid, d.stg) > d.end_value then
						return 9999
					end
				else
					return print("cannot find mission called ".. mission_name .." in quest ".. quest_name ..".")
				end
			end
		else
			return print("cannot find quest called".. quest_name .." in LIB_QUESTS_TBL.")
		end
	end
end
