[Solved] [1.7.2] odd multiplayer bug (sync issue?)

[wesserboy]

Hello everybody,

lately i've been working on a mod which can control pvp per chunk and it's coming along very nice.

 

but a few days ago i've encountered a bug and i just can't find the cause, this is what happens:

 

i run two clients from eclipse, one will host a lan world and another one will join that lan world.

the host is player1 and the one that joins is player2.

first pvp is turned off and when one of the players attacks the other one it works fine and tells me that pvp is not enabled in the chunk.

then i toggle pvp so it is enabled in the chunk.

when player1 then hits player2 it just damages him like it is supposed to.

but when player2 hits player1 it still says pvp is not enabled in this chunk and it doesn't cause any damage.

 

this is the code i use:

 

eventhandler:

worlddata:

pvp toggle command:

pvp read command:

does anyone know what could possibly cause this and how i would fix it?

if i would use coordinates i would need two sets, one for Xcoords and one for Zcoords, right? but a set only adds an element if it doesn't already contain that element, which would be a problem if two chunk have the same coordinate. or did i misinterpret what you meant?

Thank you very much, it works like a charm now

yesterday i watched some tutorials about bit operators since i had never used them, my apologies for forgetting to thank you

i've just changed my code and now it works!
