I don't know my version or loader
ReplaceBlocksMod
A utility mod that lets you replace blocks with other blocks, used entirely through the console.
The provided commands are intended to be more convenient than using the
vanilla /fill command.
Commands
1. /replace <sourceBlock> with <targetBlock>
Replaces all nearby instances of sourceBlock with targetBlock.
e.g. /replace oak_planks with cherry_planks
In Vanilla, this would be equivalent to
/fill ~-50 ~-10 ~-50 ~50 ~10 ~50 oak_planks replace cherry_planks
which is much more difficult to type and fails anyway because
the /fill command can't handle that many blocks.
2. /removegrass
Removes all nearby short grass and long grass. Regular grass blocks will not be removed.
In Vanilla, this would be similar to (but more optimized than)
/fill ~-50 ~-10 ~-50 ~50 ~10 ~50 air replace short_grass
and /fill ~-50 ~-10 ~-50 ~50 ~10 ~50 air replace tall_grass
but again, the /fill command can't handle that many blocks.
