What is the basic function to start the clock when a character goes on a quest and add 10 experience per 20 minutes on the quest. [import]uid: 35843 topic_id: 27591 reply_id: 327591[/import]
You are talking about a timer not a clock, I believe. (Unless you actually want to access the device clock?)
If a timer;
[lua]local function addXp()
–add experience here
end
timer.performWithDelay(1200000, addXp, 1)[/lua]
That said checking the device time when certain conditions are met and then calculating elapsed time may be better. Have you considered that? [import]uid: 52491 topic_id: 27591 reply_id: 112168[/import]
thank you soo much and sorry about the extra threads

i’m kinda new corona so not very good at coding o what do you mean by calculating elapsed time? [import]uid: 35843 topic_id: 27591 reply_id: 112224[/import]
It’s OK, just be mindful of it with the threads; it’s much easier to keep track of one per topic 
As to calculating elapsed time, you could get the time from the device when you start the question, for example it might be 10:20 (you’d also get seconds but I’m using minutes to keep it simple) and then you could check the time later on, say when the hero entered/exited a building, picked up an item, etc. - really any events that will happen through the course of game play. Then you would take that time and calculate the time different between the two.
Eg; if the time was 10:41 and the previous time was 10:20 as per our example then you’d know 21 minutes had passed and you should reward the extra experience. [import]uid: 52491 topic_id: 27591 reply_id: 112265[/import]
