What does this mod do?
In vanilla Minecraft, when a water block is next to at least two source blocks, it becomes a source block itself, which allows collection of infinite water. This mod allows you to configure which fluids have this behavior.

How do I use this mod?
You need Minecraft Forge installed first. Once that's done, just drop infinitefluids-version.jar in your Minecraft instance's mods/ directory and configure it to taste. (Configuration is not optional; if left unconfigured, this mod won't change anything.)

What settings does this mod have?
You can specify lists of fluids that will be infinite, with separate lists for inside and outside the Nether (and any mod-added dimensions where water can't be placed). Alternatively, you can invert the lists, so that all fluids are infinite except for those specified.

What name do I use for fluids in the configuration?
Use the name of the fluid's block that you'd use with /setblock. Examples:

Vanilla water is "minecraft:water"
Vanilla lava is "minecraft:lava"
Minecraft 1.10.2: Tinkers' Construct liquid blue slime is "tconstruct:blueslime"
Minecraft 1.7.10: Tinkers' Construct liquified slime is "TConstruct:liquid.slime"
Minecraft 1.7.10: BuildCraft oil is "BuildCraft|Energy:blockOil"

Minecraft 1.7.10: If you don't know this name, you can use Waila to see it by turning on its "Show ID:Metadata" and "Liquids" settings.

When using pumps, why do infinite fluid sources run out?
Your pumps are probably taking source blocks faster than they regenerate. Try using a larger source pool. This will allow multiple source blocks to regenerate at the same time, so they can keep up with the pumps.

Can I use this in my modpack?
Yes, even if you monetize it with adf.ly or something, and you don't need to ask me for my permission first.
