What is Copycats+ aeronautics weight?

1 part

Copycats+ aeronautics weight is a small compatibility mod between Create Aeronautics and Copycats+. It gives the Copycats+ copycat blocks more reasonable kpg (mass) values, so they behave sensibly in the Sable physics library that Create Aeronautics builds on.[1]

It covers every block from Copycats+. Some blocks scale with how much you stack: on copycat layers, more layers means more kpg. If you build contraptions out of copycat blocks, this mod is what gives them their weight.[1]

In this pack

The pack's mod list includes Copycats+ aeronautics weight 1.1.0, shipped as the file aerocopycats-1.1.1.jar. It has been part of the pack since version 1.0.3 or earlier.[2]

The mod is a compatibility layer, so it adds nothing you craft or place yourself. Its registry namespace is aerocopycats.[1]

How do you get started with Copycats+ aeronautics weight?

2 parts

Copycats+ aeronautics weight is a small compat mod. It connects Create Aeronautics and Copycats+ by giving copycat blocks more reasonable kpg (mass) values.[1]

The mass values are for the Sable physics library, which Create Aeronautics uses. So this mod only matters once you build something that Sable simulates and it contains Copycats+ blocks.[1]

What it covers

  • It includes kpg values for all blocks from Copycats+.[1]
  • For blocks like copycat layers, more layers means more kpg, so a thicker stack weighs more than a thin one.[1]

Your first steps

You don't need to set anything up for this mod. Build with Copycats+ blocks as you normally would, and keep their weight in mind when you add them to a contraption. Heavier copycat builds, such as stacked layers, will weigh more.[1]

Unverified The sources here show no recipes, quests or config files for this mod in the pack. If you want to check for any of these, look in the pack's own quest book and config folder.

How does Copycats+ aeronautics weight work?

2 parts

There is not much machinery to learn here, and that is the point. Copycats+ aeronautics weight is a small compatibility mod between Create Aeronautics and Copycats+. It has no machines, multiblocks, power, fluids or item handling to set up.[1]

What the mod does

It gives copycat blocks more reasonable kpg (mass) values. Those values are used by the Sable physics library, which Create Aeronautics and similar mods rely on.[1]

It includes mass values for all the blocks from Copycats+. That means any Copycats+ block you put on a contraption has a sensible weight in the physics simulation.[1]

Layered blocks

Some blocks get more than a flat value. For copycat layers, more layers means more kpg, so a thicker stack of layers weighs more than a thin one.[1]

Tip: Because the mass comes from the block itself, you do not need to configure anything. Build with copycats as normal and the weight is accounted for by the physics.[1]

What changed in Copycats+ aeronautics weight between versions?

1 part

Copycats+ aeronautics weight has a short history in this pack. FTB Skies 2: Aero 1.10.0 ships version 1.1.0 of the mod, and the jar file in the pack is named aerocopycats-1.1.1.jar. The mod was first included in FTB Skies 2: Aero 1.0.3 or earlier.[2]

Mod changelog

  • 1.1.0: fixed incorrect copycat slope weight. If you build ships with copycat slopes, this is the fix that corrects their weight.[3]
