[1.7.2] Changing a block at an (x, y, z)

[libarclite]

In the 1.6.4 code, I could change a block at a chunk coordinate like this:

 

world.setBlock(pt.posX, pt.posY, pt.posZ, blockID, 0, 3);

 

How do I do this in the 1.7.2 world?

Probably the same way.  Except that that function likely isn't deobfuscated yet.

 

You need to look for a function that returns void and takes 6 integers as an input.

World.func_147449_b(Xcoord, Ycoord, Zcoord, Blocks.stone);

Like Draco18s said

I'm finding this really helpful:

 

bbdiff forge/mcp/src/minecraft/net/minecraft/world/World.java MinecraftForge/eclipse/Forge/src/main/java/net/minecraft/world/World.java

 

Diffing the older sources against the new ones. This tells me that

 

World.getBlockId() now maps to World.func_147439_a(), which now returns a Block.

 

What's the best way to contribute these findings to mcp?

The function that seems to be the equivalent, with the metadata and flags variables seems to be:

 

world.func_147446_b(x, y, z, block, a, b);

 

...now if I could just figure out a way to get all the block names/references -- the list of static final Block variables having been replaced with something else is looking like a nightmare to me.

have you used the icq MCPbot before?  It's a bit clunky to do it manually but if you are any good at scripting that might be the easiest.

 

DieSieben has expressed some interest in writing a decent web interface for querying and making suggestions about mappings.  I'd recommend talking to him about it; you could try contacting the MCP guys but I haven't had much luck with that myself, they are very busy folks.

 

Ultimately I dream of a day when Mojang just release their source directly (with comments removed and variable names anonymised, of course).  Would save everyone a whole heap of trouble and speed up the release cycle a huge amount.  I'm sure the idea has been thought of, don't know why it hasn't happened since I can't see any disadvantage for Mojang.  Anything which helps the modding community will help extend the life of Minecraft, which is getting rather mature now.  Anyway that's for more influential folks than me to progress...

I did try to generate some queries with the mcp bot. The IRC experience has never been my cup of tea. I'd much prefer having a git repository somewhere that holds the mappings. If that's not practical, sigh.
