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.
