Using the features
WaterLogging Structure Processor fixer
The WaterLogging fix is applied directly into your template_pool. When creating a pool add the processor ftbpc:waterlogging_fix_processor to your processors list. The companion will now figure out when a block shouldn't be water logged and fix it!
It should look like this
{
"processors": [
{
"processor_type": "ftbpc:waterlogging_fix_processor"
}
]
}
RandomNameLootFunction
The RandomNameLootFunction it a LootItemFunction that allows you to set an item's name based on a list of names. This requires a list of Component's in JSON format to be placed in the data/ftbpc/sources/random-name-loot-source.json folder. You can use a datapack or KubeJS to modify this file as by default, it simply contains an example.
Example of how the json file should look
{
"example": [
{"bold":true,"color":"blue","text":"I'm an examples!"}
],
"list2": [
{"text":"I'm an example 2!"},
{"text":"More than just one"}
]
}
Each key in the Map / Object List must be unique as it's used as the identifier category for the loot function to find a random name. As you can see, you need to use a fully JSON compliant Component for the function to work correctly. Errors will be logged if this is done wrong.
Here is what the loot table can look like to take advantage of the above json file
{
"entries": [
{
"type": "minecraft:item",
"name": "minecraft:stone",
"functions": [
{
"function": "ftbpc:random_loot_item_function",
"nameSetKey": "example"
}
]
},
{
"type": "minecraft:item",
"name": "minecraft:gold",
"functions": [
{
"function": "ftbpc:random_loot_item_function",
"nameSetKey": "list2"
}
]
}
]
}
