How to empty inventory.

[ExpectedIdentifier]

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?

You won't get an error I don't think. Also for things such as tinderboxes/laudanum, just count up how many you have on the entire map and remove that many, that way the inventory will be empty no matter how many the player picks up.
