How to empty inventory.

[The chaser]

you have to call this method for every item you have in the inventory:

void RemoveItem(string& asName);

Isn't there a way to reset everything?

also if I try to remove a lantern, but the player doesnt have one, does it give an error or something? or should i check if the player has one first?

It doesn't give any error. No, there isn't a way to reset everything.
