[Script] Quest requires 'X' hours after the start

 

Hello!

 

In this thread I am posting an example of script that will allow you to check the condition when the player completes the quest: 'X' time has to pass after starting the quest to complete it.

 

 

Usage

MisResultCondition(MissionTimeExpired, <quest_id>, <time_in_seconds_to_wait>)

 

Installation

 

Add the following code to the file 'vairable.lua':

-- Table with the time of taking quests by characters
if (quest_table_guard == nil) then

	quest_table_guard = true
	quest_table = { }

end

 

Add to the file 'functions.lua':

-- Quest added event
AddMission__Original = AddMission
AddMission = function(role, id, param)
	
	-- Call original AddMission function
	local ret = AddMission__Original(role, id, param)
	
	-- Check the result
	if ( ret == LUA_TRUE ) then
	
		-- Add the quest to the table
		quest_table[id] = quest_table[id] or {}
		
		-- Remember the time when the character took the quest
		quest_table[id][ GetRoleID(role) ] = os.time()
	
	end

	-- Return original result
	return ret

end

-- Check that some time expired since character taken the quest
function MissionTimeExpired(role, id, t)

	-- Check that quest exists in the table
	if ( quest_table[id] == nil ) then
		
		-- Quest not found
		return LUA_TRUE
		
	end
	
	-- Get character ID
	local cha_id = GetRoleID(role)
	
	-- Check that the character has the quest
	if ( quest_table[id][cha_id] == nil ) then
	
		-- Character doesn't have the quest ?!
		return LUA_TRUE
	
	end
	
	-- Calculte time delta
	local delta = ( os.time() - quest_table[id][cha_id] )
	
	-- Check that t seconds expired since quest started
	if ( delta >= t ) then
		
		-- Remove character from table
		quest_table[id][cha_id] = nil
		
		-- Condition is completed
		return LUA_TRUE
	
	end
		
	-- Condition is not completed
	return LUA_FALSE
	
end

 

And finally register the new function in the file 'MissionSdk.lua' ('ConditionsTest' function):

. . .

elseif conditions[i].func == MissionTimeExpired then
	local ret = MissionTimeExpired( character, conditions[i].p1, conditions[i].p2 )
	if ret ~= LUA_TRUE then
		PRINT( "ConditionsTest: MissionTimeExpired = false" )
		return LUA_FALSE
	end
	
. . .

 

That's all! 

 

Note:

1) All data about the time of taking quests by characters will be lost when the server is restarted. You need to come up with a mechanism for saving the table 'quest_table' to a file or database if this is critical for your application;

2) NPCs that give and accept a quest with this condition must be within the same GameServer instance.
