What’s new in 1.2.0:

Symmetry (map maker): build only one quarter of a 4-team map and let Cloude Wars copy it. In setup mode, stand in the quarter you want to build and type /bw setBuildSymmetry quarter nomiddle [size]. Each quarter is size × size blocks around x 0, z 0, and the size is 64 if you leave it out. The other three quarters get a terracotta floor at y 64, so you can see where yours ends. When you’re done, type /bw syncSymmetry. Your quarter is copied into the other three, turned the right way: stairs, beds, logs and so on face the right direction. Chests and signs keep their contents, and team blocks go to the next teams (#1# becomes #2#, #3#, #4#). Team blocks on 26.3: the new wool and concrete slabs and stairs work as team blocks. This needed no code change, because team blocks swap “white” for the team color by block name. I confirmed it in a real 26.3 game: the slabs and stairs turned lime and orange with their shapes kept.

What’s new in 1.2.1:

Half symmetry (map maker) for 2-team maps. Stand in the half you want to build. The line between the halves is x 0 or z 0, whichever you stand farther from. Then pick one: /bw setBuildSymmetry half nomiddle mirror [size]: the copy is mirrored across the line. /bw setBuildSymmetry half nomiddle central [size]: the copy is turned around the middle, so both teams have the same things on the same side (like the ender chest on their right).

The other half gets a terracotta floor at y 64 until the first copy. Then /bw syncSymmetry copies your half:

stairs, beds, logs and doors face the right way, and mirrored doors swap their hinge side chests and signs keep their contents team blocks go to the next team (#1# becomes #2#)
