dont-starve
When you die in Don't Starve, an XP bar appears, telling you the progress to unlocking the next character.
How is this calculated? Is there a set amount of XP you get for each day you survive, or does it increase over time? Do you get XP for other actions, like killing monsters, crafting more complicated items etc.
You can find all the informations you need on the wiki.
Basically at the start of the game you're given a treshold of 30 Naughtyness. Every action damaging a "nice" creature subtracts points from this treshold according to the following table:
When you reach 0, one or more Krampii (Krampuses?) will spawn, depending on the days you've survived:
Every 60 seconds spent not doing naughty actions will increase your threshold by one, so this means that if you try to space out your killings in time, you can safely keep hunting for your meat without fearing to meet Krampus. On the table above the "Treshold" column indicates the maximum naughtiness you can have. It has been put in there because it's supposed to go down the more days you play, but there's still an uncertainty on the exact numbers, hence the interval.
Probably wasn't available when question was asked:
From Main Menu, go to Options, Pick Controls, and you can set custom keys.
Best Answer
Each day survived in Sandbox Mode gives exactly 20 XP. Adventure Mode does not reward any experience. To unlock all characters, you need to survive a cumulative 96 days. There is no experience reward for other actions such as killing or crafting.
