GMS Like Snowball Event (Uses packets)

[kevintjuh93]

I saw that the Snowball release was bumped, and I had to release this snowball event because I find the other one stupid.
Why?Mine uses packets so no stupid checks in CloseRangeDamageHandler. And that Snowball Event was originally Bassoe's work.

net/RecvOpcode.java (v83)

    SNOWBALL(0xD3),
    LEFT_KNOCKBACK(0xD4),

net/SendOpcode.java

    ROLL_SNOWBALL(0x119),
    HIT_SNOWBALL(0x11A),
    SNOWBALL_MESSAGE(0x11B),
    LEFT_KNOCK_BACK(0x11C),

Want SendOpcode for other versions? REACTOR_DESTROY + 1

net/PacketProcessor.java

            registerHandler(RecvOpcode.LEFT_KNOCKBACK, new LeftKnockbackHandler());
            registerHandler(RecvOpcode.SNOWBALL, new SnowballHandler());

How to use?
1. For now only Lith Harbor is supported. So go to Lith Harbor and type /scheduleevent snowball
2. People can now go to the event map by talking to Jean. (There is a limit of 50 people that can participate)
3. When either the limit is reached or you think you can begin type /warpsnowball
4. Maybe show the event instructions, packets should be in your source
5. Wanna start the event? Type /startevent
6. Now watch it or leave.

I might have forgotten something, if yes please post what.
Never been tested with a lot of people. But should work . Report any bug you find
If you want to have it GMS Like, ask it and I will post the other npc which are needed when you have lost or won the game. (Should already be posted somewhere on the forums.)

Anyways have fun :3 Snowball ftw

Don't post this anywhere else. RageZone > All

 

[iem214u]

Very Nice! Thanks!

 

[Kaynu]

Very Nice! Thanks!

There is no way that you could have looked at all that in the time between when he posted and you posted.

 

[KenoRIK10]

Very nice as usual kev =)
Keep up the good work!

 

[DejaVu]

Impressive.

 

[Sparrow]

Nice Kev, so pro ;D

 

[kevintjuh93]

Nice Kev, so pro ;D

Thanks everyone,

I already knew that it used recvops but whenever I tried to hit it, it wouldn't sent a packet to the server. Only occured when sending a packet that made the snowball roll to the end. So I've tested and tested and found out I could sent 2 packets. One to make it roll and one to make it send a packet to the server. And hooray :3

 

[AuroX]

By the way, you misplaced a } in the NPC Script i guess?..

 

[kevintjuh93]

By the way, you misplaced a } in the NPC Script i guess?..

Thanks, never thought of that because it actually worked. But thank you very much :3

 

[Buya]

Nice but as far as I can remember the snowball thing was in happyville where you attacked that mobs which had a huge amount of hp and then they dropped alot of things :O
Anyone explain please?

 

[AuroX]

Umm, is there some bugs with the timer?..lols.. Sometimes I type /startevent and the timer shows, however, on the other hand, sometimes whenever i type that command, the timer doesn't shows..

-AuroX

Hmm, maybe that sometimes is in the same channel, when an event was already there? Or not?

 

[Darkstanx]

How can I get the ball move faster?
EDIT: NVM i figured it.

 

[wackyracer]

Omg thank me









jk. kool release Kev -insert F3 here-

 

[hecari]

It crashes after I warped with error code : -83 or 83(forget le).

Source Used:

XiuzSource v62(changed all I could change in order to be compatible with XiuzSource).

 

[kevintjuh93]

v62 packets are needed:
SendOps:

    ROLL_SNOWBALL(0xDA),
    HIT_SNOWBALL(0xDB),
    SNOWBALL_MESSAGE(0xDC),
    LEFT_KNOCK_BACK(0xDD),

RecvOps:

    SNOWBALL(0xB2),
    LEFT_KNOCKBACK(0xB3),

 

[JvlShiz(fail)]

don't you know how to use arrays?

 

[kevintjuh93]

don't you know how to use arrays?

Wut? F6

 

[hecari]

v62 packets are needed:
SendOps:

    ROLL_SNOWBALL(0xDA),
    HIT_SNOWBALL(0xDB),
    SNOWBALL_MESSAGE(0xDC),
    LEFT_KNOCK_BACK(0xDD),

RecvOps:

    SNOWBALL(0xB2),
    LEFT_KNOCKBACK(0xB3),

I already have those packet but it's still not working.
