Adding xp to a skill.

[khalil]

I've been trying to figure out how to add xp to a randomly chosen skill for a while.
Currently I've got the randomly chosen skill bit down, but I'm still not sure how to add xp.
I tried to figure it out via the code for pot of experience, but that seems to be spread out through three different files and I can't figure out how it works.
Is there some kind of function to call? Any help would be greatly appreciated.

The potion seems to set you.exp_available to a value, then after determining which skills are enabled it calls train_skills().

Huh. Thanks! I've never been good with things in three or more files.

You might also look into how sage works, which is fairly similar. See the "if (!you.sage_skills.empty())" block in player.cc:gain_exp(). It saves the existing exp pool (you.exp_available), sets the pool to the amount of XP it wants to give, calls train_skill(), then restores the old value of the pool.

I'll try that too.
I allready got the code for randomly choosing a skill from there, might as well go all out.
