[1.10.2] What is "flag" 11?

So I see at some code in Minecraft, for example when a bucket picks up water or lava, that it uses flag 11 for the updates.

 

What does 11 actually do there?

 

I though flag 7 was the higher one.

    11 would be flags 1 + 2 + 8.

    I've never figured out what Flag 8 does.

    Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

    RenderGlobal#notifyBlockUpdate

    passes the 

    boolean

    value of flag 8 to 

    RenderChunk#setNeedsUpdate

    . I don't fully understand the world rendering code, but this appears to signal that the 

    RenderChunk

    should be rebuilt from the current world data.

    Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

    flag 8 seems to be used in RenderGlobal.notifyBlockUpdate() which passes true as a parameter to RenderGlobal.markBlocksForUpdate() if flag 8 is set.

     

    markBlocksForUpdate() passes that flag as a parameter to the ViewFrustrum#markBlocksForUpdate() method which passes it as the only parameter to renderChunk#setNeedsUpdate().

     

    So basically it tags the entire chunk for a rendering update it seems.
