Coords I'm teleporting to (pest control game):

2667, 2594

Map data for that area (10536):

Code:

1202512092
-698870718
-2083455397

Error I receive:

Anyone have any ideas as to what is causing this? I've checked the packet structure against the client one, and I'm pretty sure I'm calculating everything right (looked at Pali's 523 version).

EDIT: sometimes I also get an OutOfMemoryError.

Okay peter gave some insight into it, I'll keep this topic up though.

**Hotyute** · 07-07-2009, 09:12 PM

well first of all u don't loop 1, 1 bits all the time, pali did his all wrong

freking BUMP
graham. if you cant solve it, no one can lmao.

**Graham** · 08-12-2009, 11:51 AM

Stop bumping!!!!!!. This topic isn't needed any more. My code is very nearly correct there anyway and I have it on 317 too: [Only registered and activated users can see links. ].

Bump for the laugh.
