[OBSOLETE] WorldEdit 5.4 schematic negative block ID fix

[mushroomhostage]

WorldEdit 5.4 has trouble with //schem load and //paste involving blocks with IDs >127, which occurs quite often with mods. The paste will fail with:

Code: [Select]

This occurs because the block ID is stored as a "byte", with range -128 to 127. It wraps around and causes the negative bounds error. For details see https://github.com/sk89q/worldedit/pull/192 .

Until this is properly fixed, I have a workaround available at: https://github.com/mushroomhostage/worldedit/downloads

Disclaimer: not necessarily a complete fix. See pull request discussion for possible caveats. Also note, this does not add compatibility with 4096 block IDs. Someone else I hear is working on another patch for that. This simple fix worked well for my purposes (copying schematics of abandoned factories and such for my server), and there was interest in this patched build from other server owners, so I figured I'd post about it here in case anyone else is looking for it as well.

This should no longer be needed in the latest WorldEdit builds, which now have initial 4096 ID support:
