About this Mod
This mod allows for block replacement in a "creative" sense (doesn't require to be used in Creative gamemode), it'll no require the use of the blocks being placed, it simple needs an example of the block and will then replace as many blocks as required within range [square].
it works in 2 main ways:
- 1 - tool options: replaces blocks right-clicked with tool with the block type that is held in the offhand when crouching. (the tools can be specified in the config) along with their respective ranges.
- 2 - command option: the command "/replace [range]" can be used to replace the block type being stood on by that in the offhand.
the config also has "cant_replace" and "cant_be_replaced" options to prevent selected blocks from being used or replaced as well as a "needs_advancement" option incase you'd like this to only be available for those which have opened the advancement selected.
