Spiffy Bottle Tutorial
by Weasel

This tutorial is pretty basic. Most experienced RM2k people could figure
 this out on their own and maybe some beginners could too. This is
just a way to add a little extra spice to your game to make it more fun
and maybe more challenging.

This is a way to make bottles like in Zelda games. In these games, 
you must get a bottle in order to get items such as potions or other 
things. If you do not have the bottle, you do not get the item. If you 
have a bottle, you can fill it with something. Here's how:

My example uses an empty bottle and a bottle filled with potion.
1. Make an item called Bottle. Give it a discription that says "It's empty!"
 and make it a switch so it activates a switch.
2. Go to the common events and name one of them "Bottle". Make it 
a Parallel Process and check the box next to it. Select the switch 
you made for the bottle.
3. In the event commands box, make a message: "This bottle is empty!"
4. This is optional: Show choice(Do you wanna learn about bottles?)
(Back to game). After the learn about bottles, make a message that
 says how the bottle system works.
5. After this is done, turn OFF the switch for the bottle.

This is the regular bottle. What happens is the hero tries to use
 the bottle but it is empty and he can't use it.
Now we  must have an item to go into the bottle.
1. Make an item called Bottle: Potion. Discription: "It's full of Potion!"
 and make it activate a switch. Name the switch appropriately.
2. Go to the common events and name one "Potion Bottle!".
 Make this a parallel process and check the box next to it.
 Select the switch you made for the potion bottle.
3. A message: The party drank the potion and all HP
 and MP was recovered!"
4. Click 'Full Recovery' in the event command choices and
 set it to all party members.
5. Message: "The bottle is now empty"
6. Add item: Bottle add only one
7. Remove item (It's in the command ADD ITEM, just click
 the box for Drop item) Remove Bottle: Potion , be sure to remove only one
8. Turn the potion bottle switch off.

ALL DONE! When the party drinks the bottle of potion, the
 team is recovered and the bottle is now empty.
Next, we must find a way to fill the bottle. It's not really hard.
 All it requires is a few Fork Conditions. Simple stuff.

1. Make an event on any map and give it a picture (I used an old
 man because he is a magic potion salesman or whatever). The
 event is on hero touch, same level as hero, blah-blah-blah.
2. Message: Would you like to try some of my Potion? You will
 need a Bottle to fill it in and it only costs 100 Gold!
3. Show choice: yes or no.
4. Under yes make a Fork Condition. Set it to Item: Bottle;
 Must have. Make sure the ELSE case box is checked.
5. Under the ELSE case, Message: You need an empty
 bottle to put the potion in!
6. Under the Fork, make another Fork Condition, this
 time setting it to Money: 100; above
7. Under this new ELSE case, have a message that
 says to come back with more money.
8. under the money fork, make a message that says
 you got a potion in a bottle.
9. Add item: Bottle: Potion; 1
10. Remove item Bottle (remove only 1)
11. Change Gold held, remove 100 gold.

That's it!
