JACS Classic Guide:
There are 5 types of JACS robots the player can create:
Every robot except for the turret JACS can be tamed.
Every robot can be healed for 30 HP using redstone.
Big Guy can also can be rideable, which makes traveling through the overworld an easy task, as they're fast and able to jump high distances.
To get started, you will need to create the JACS Summon. This is an item that you can throw that will spawn JACS into your world. If you want to add modes, keep this summon as it will be needed to craft shooter and turret modes as well as Big Guy.
These are the components needed to create shooter and turret modes.
To create mode summons, the regular JACS Summon and a component will have to be paired together.
Big Guy being a powerful robot will also require a good number of resources to craft.
Recycled JACS is created using 4 pieces of recyclable parts. A part is only gained whenever a craftable JACS robot is destroyed. This robot cannot be used to change modes and will not drop a recyclable part when destroyed.
JACS robots can be tamed and to do so, you will need a follower chip. These chips will 100% guarantee tame any of the robots except for turrets. If you need to move your turret robot, every robot can also be leashed!
Before using this addon in your world, remember to turn Holiday Creator Features on in experiments.
NOTE: While you can install both the full and classic editions, it is not recommended to put both versions in the same world.
