[Add-On] Super Gachapon

Bored. Made what I like to call a 'Super' Gachapon. It's very adaptable to high and low rate servers, simply follow the directions in the comments. It's also adaptable in the fact that you can choose whether or not you want players to be able to gain more than 1 of the same item from the Gachapon.
Read the comments, I think I left enough.

NPC Script:
(Make sure you put your item IDs in the array)

PHP Code:

Methods you'll need in the source (which are also useful in plenty of other situations):

Spoiler:

MapleInventoryManipulator:

PHP Code:

---

public static void editEquipById(MapleCharacter chr, int itemid, byte stat, short value) {
editEquipById(chr, itemid, stat, value, false);
}

public static void editEquipById(MapleCharacter chr, int input, byte stat, short value, boolean superGacha) {
Equip equip = null;
if (superGacha) {
equip = (Equip) chr.getInventory(MapleInventoryType.EQUIP).getItem((byte)input);
equip.setStr(value);
equip.setDex(value);
equip.setInt(value);
equip.setLuk(value);
equip.setWatk(value);
return;
}
equip = (Equip) chr.getInventory(MapleInventoryType.EQUIP).findById(input);
switch(stat) {
case 1:
equip.setStr(value);
break;
case 2:
equip.setDex(value);
break;
case 3:
equip.setInt(value);
break;
case 4:
equip.setLuk(value);
break;
case 5:
equip.setWatk(value);
break;
}
} 


---

MapleCharacter:

PHP Code:

---

public void sendServerNotice(String msg) {
MaplePacket packet = MaplePacketCreator.serverNotice(5, msg);
try {
client.getChannelServer().getWorldInterface().broadcastMessage(name, packet.getBytes());
} catch (RemoteException e) {
getClient().getChannelServer().reconnectWorld();
}
} 


---

NPCConversationManager:

PHP Code:

---

public void editEquipById(int input, byte stat, short value, boolean supergacha) {
if(supergacha) {
MapleInventoryManipulator.editEquipById(getPlayer(), input, stat, value, true);
return;
}
MapleInventoryManipulator.editEquipById(getPlayer(), input, stat, value);
}

public void reloadChar() {
getPlayer().getClient().getSession().write(MaplePacketCreator.getCharInfo(getPlayer()));
getPlayer().getMap().removePlayer(getPlayer());
getPlayer().getMap().addPlayer(getPlayer());
}

public byte gainItemRetPos(int itemid) {
MapleItemInformationProvider ii = MapleItemInformationProvider.getInstance();
IItem it = ii.getEquipById(itemid);
byte ret = getPlayer().getInventory(MapleInventoryType.EQUIP).addItem(it);
c.getSession().write(MaplePacketCreator.addInventorySlot(MapleInventoryType.EQUIP, it));
c.getSession().write(MaplePacketCreator.getShowItemGain(itemid, (short)1, true));
c.getSession().write(MaplePacketCreator.enableActions());
return ret;
}

public void serverNotice(String msg) {
getPlayer().sendServerNotice(msg);
}

Shoutout to Nemesis <3 Thanks for helping!
If Nemesis decides to post on this thread, thank him :P
Oh, and Soulfist deserves some credit as well.

Feel free to flame me <3

Why do people even bother to use switch, it's dumb.

The methods seem more useful then the NPC.

Switch / case is faster than if / else >_>

Quote:

In some languages and programming environments, the use of a case or switch statement is considered superior to an equivalent series of if-else statements because it is:

* easier to debug (e.g. setting breakpoints on code vs. a call table, if the debugger has no conditional breakpoint capability)
* easier to read (subjective)
* easier to understand and therefore
* easier to maintain

Additionally, as mentioned above, an optimized implementation may:

* execute much faster than the alternative, because it is often implemented by using an indexed branch table

For example, deciding program flow based on a single character's value, if correctly implemented, is vastly more efficient than the alternative, reducing instruction path lengths considerably.

@magelight: They are rofl. And I answered your npc prob on my thread.

reloadChar is useless, there's a packet to update equip stats. There's a packet to update character appearance too.

Also switch isn't faster than if in Java

lol

This is not done here, and you can probably do this using if/else too

What packet might that be?
And thanks for the info on if/else and switch.

I don't see the "Super" part of this, this one just gave me more reasons to sleep...

hmmm, nice release =D I'll tell you if it has any problem with it

Yay more NPCs

It's more organized and you don't have to put in tons of }else if(){

So you did release it chris, good job o-o.


@Osiris, "Super Gachapon" was my name for it because I made a rough draft. It was his idea tho ;)

Well that's true, but you have a fat list of lines of case and breaks. I use switch sometimes since it's a little easier to read but if statements are more powerful. What if you wanted a range of numbers: so 1-100 would return 1, 101-2400 would return 2, otherwise return -1? Then you'd use if. Switch looks better in some cases such as if (x==1||x==3||x==100|x==235||x=25) {}

PHP Code:

---

var Prizes = [["common prizes"], ["standard prizes"], ["rare prizes"], ["extremely rare prizes"]]; 


---

should be:

PHP Code:

---

var Prizes = ["common prizes", "standard prizes", "rare prizes", "extremely rare prizes"]; 


---

I don't see whats the point of the extra brackets

Like i said, the very base of this NPC is mine. I did that because instead of handling it in seperate arrays, you could set it up like [rare], [common], etc etc. You could randomize each array seperately, that was the original intent. If you did it like your suggesting Akira, it would completely defeat the purpose :(:

Either way. I too find the methods more useful *copy pastes* :D:

4 separate classifications of item IDs, so I used 4 separate arrays.

PHP Code:

---

[[lvl 30 claw id, lvl 30 sword id], [lvl 50 claw id, lvl 50 sword id], [lvl 100 gear, more lvl 100 gear], [timeless shit, timeless shit]]; 


---

Just as an example.
If you had reviewed the whole script you probably would have gotten your answer.
