[SCRIPT] Checkpoints and autosave help

[serbusfish]

First of all i'm wanting to put a checkpoint in place so that if a monster kills you you respawn close by but the monster is gone. I know this is like the default thing that happens but I cant figure it out, I have a player start area in place, im just not sure what to do with this:

void CheckPoint (string& asName, string& asStartPos, string& asCallback, string& asDeathHintCat, string& asDeathHintEntry);

Do I put this in the part of the script that spawns the monster? And what would I put for the 'string& asCallback' bit?

Second question, I was just wondering how the 'void AutoSave();' command works, do I put this at the beginning of a map or the end? And if say, items have been collected, if the player exits and reloads will the game have saved this or do I need to put auto save commands in the scripts after item pickups? And do I need to assign start areas or will it just start at the place you exit at?
