[1.10.2] What is "flag" 11?

[American2050]

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.

[Choonster]

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.

[jabelar]

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.

Thanks a lot I thought the only flags possible were 1, 2 and 4, didn't realized there was flag 8 also.
