WARNING!
MOD REQUIRES CURIOS API TO FUNCTION!
(everything outside of that is built in)
Mod that adds simple industry and military related equipment, items, vehicles and blocks
The aim of the mod is to add industry and military related content without the bloat and complication of most mods. Most automation can be done with vanilla redstone blocks/items.
The industry component of the mod allows for very fast industrial expansion and once the player has some resources, the growth becomes rather exponential. This allows you to fuel any mining, infrastructure or warfare needs you might have.
Tips:
Crafting recipes for everything can be unlocked by picking up basic items like iron, leather, coal, etc. (But JEI also can be used)
Vehicles need to be fueled with Fuel, which you get after smelting or blasting Oil Buckets.
To extract oil from oil veins/ores, you need to connect minimum 3 oil extraction pipes to it, then place an Oil Well block on top of a pipe, then place 5/10/15 Oil Extraction Cables on top of the well, then on top add an Oil Pump block which can be activated with a redstone signal.
Signal needs to be constant.
While this is active you will slowly be able to extract oil for very long.
Size of well, or basically amount of Oil Extraction Cables in the structure, decides how much oil you get.
Extraction rate is one load each ~20 seconds.
Combinations of running a specific Oil Well size in a specific biome can often yield surprisingly good results! You might pull out not only Oil but also some 'trash' that will be quite useful!
Oil veins are packed with Oily Sludge and are also extremely volatile.
Explosion of one can criple an entire oil field you built with a chain reaction. Keep Creepers away!
