v142 WARP_TO_MAP Analyzing Help

[ExtremeDevilz]

I have been trying to understand on how packets work for sometime now, as far I know I came across a halt I took this packet from a v142 private server and started to compare it with the source released...

I have written the part where Im stuck at how does that packet equals to what I got etc.. thanks..

Done some of the work for you. If you're getting stuck on that part; I suggest learning more before attempting with packets. Additionally, stop writing "WTF" and "WTF Nexon" just because you don't know what those are.

I know the addCharstats I can figure out the after that
