I've got a question, do you want to make it like runescape where you have wood and flint and you need both to make said fire.
cause I could make a good system like that that uses terain tags and knows where you can and can't make a fire and where it would take less time to (I will make it so it takes longer in different places), eg.
you can make a fire on grass - 5 sec
on dirt - 2 sec
on water - can't make fire
on a cliff - can't make fire
(Do you want me to make this or are you 100% satisfied with the previous posts

and don't)
