Documentation on lists:

parameters:

Parameter name Type Default Example
modid String (abc) - minecraft / etfuturum / hbm / Thaumcraft
itemname String (abc) - stick / beetroot / item.part_generic / blockCustomOre
metadata Int (123) 0 0 / 4 / 1 / 5
ignoremeta Boolean (true/false) false true / false
fluid String (abc) fluid.tile.water if vanilla (water/lava) - fluid.tile.water fluid.tile.lava, else (thermal foundation, etc) - fluid.redstone, etc

burnList:

Minimum syntax:

  • modid:itemname
    • Example: minecraft:blaze_rod

Means that item "itemname" from "modid" will NOT burn in lava

Maximum syntax:

  • 1)modid:itemname:metadata
    • Example: minecraft:golden_apple:1 //enchanted

OR

  • 2)modid:itemname:ignoremeta
    • Example: etfuturum:netherite_sword:true

Means that item "itemname" from "modid" : 1)with metadata "metadata" 2)with any metadata will NOT burn in lava

With B:invertBurnList=true everything is exactly the opposite: the items specified in this list will be the only ones that WILL burn

(it follows that absolutely all other items not on this list will NOT burn)

floatList:

Minimum syntax:

  • modid:itemname
    • Example: minecraft:stick

Means that item "itemname" from "modid" will float in water

Maximum syntax:

  • 1)modid:itemname:metadata-blocked:fluids[]...
    • Example: etfuturum:tipped_arrow:8227:fluid.tile.lava

OR

  • 2)modid:itemname:ignoremeta:fluids[]...
    • Example: etfuturum:netherite_sword:true:fluid.tile.lava:fluid.redstone

Means that item "itemname" from "modid": 1)with metadata "metadata" 2)with any metadata WILL float in fluids "fluids[]"

With B:invertFloatList=true everything is exactly the opposite: the items specified in this list will be the only ones that will NOT float in the specified fluids.

(it follows that absolutely all other items not on this list WILL float in all fluids)

Note when specifying fluids: if it's vanilla water/lava, use fluid.tile.water or fluid.tile.lava. When specifying mod fluids, just use fluid.fluidname (without .tile)

ignitingItemsList:

Minimum syntax:

  • modidItem:itemname:modidBlock:blockname:chance
    • Example: minecraft:torch:minecraft:fire:10

Means item "itemname" from "modidItem" will ignite block underneath it with the block "blockname" from "modidBlock" with a chance of "chance"

May be difficult to understand, but it's much simpler:

modidItem:itemname - an item from some mod. Let's call it "A"

modidBlock:blockname - a block from some mod. Let's call it "B"

chance - a number, from 1 to 100

So, if an item “A” falls to the ground, then with this chance it can replace the block in which it is located with a block “B” (the replacement can only occur if the item “A” is in an air or grass block)

Maximum syntax:

  • 1)modidItem:itemname:metadataItem:modidBlock:blockname:metadataBlock:chance
    • Example: minecraft:red_flower:6:minecraft:stained_glass_pane:5:100

OR

  • 2)modidItem:itemname:ignoremetaItem:modidBlock:blockname:ignoremetaItem:chance
    • Example: minecraft:golden_sword:true:minecraft:stained_glass_pane:7:100

everything is the same, but now with indication of metadata/its absence (default metadata is 0)

With B:invertIgnitingItemsList=true everything is exactly the opposite: the items specified in this list will be the only ones that will NOT ignite blocks (all other items will ignite blocks with vanilla fire)

EXTRA syntax:

  • oredict:modidBlock:blockname:chance

For explosionList / undestroyableList / sulfuricAcidList the syntax is exactly the same as for burnList
