[1.7.10] Send long in container via sendProgressBarUpdate?

Recommended Posts

Hi, this is my question:

Is it possible, and yes - how,  to sync long between containers (server-client)? Or i have to use packets???

 

Why i am using longs: in my tileentity, because of use of big numbers, multiplications of integers wre going wrong (10000*989000=-216578532), so i decided to use longs instead...

 

Thanks for help!

If you have any questions - just ask!!!

The most you can use is a short, as you already know. But via some bit-tricks you can transform a long into 8 short values.

 

Encoding:

[nobbc]long l = <someLongValue>;
short[] shorts = new short[8];
for (int i = 0; i < 8; i++) {
    shorts[i] = (short) ((l >>> (i << 3)) & 0xFF);
}[/nobbc]

 

Decoding:

[nobbc]short[] shorts = <the shorts>
long l = 0;
for (int i = 0; i < 8; i++) {
    l |= (((long) shorts[i]) << (i << 3)) & 0xFF;
}[/nobbc]

 

Then sync all the 8 shorts.

Untested, but this should work.

Otherwise, use a custom packet.

 

Thanks, i'll try it!!!
