Simulated Copycats

An addon for Create Aeronautics

Ever wanted your airships to be built from blocks that look normal but behave completely differently?

Simulated Copycats adds a new collection of copycat blocks for Create Aeronautics with special simulated properties that can completely change how your contraptions fly, drift, crash, bounce, and survive.

Build lighter-than-air hulls.
Create sticky landing pads.
Make ice-slick runways.
Accidentally vaporize your ship because half the frame was fragile.
Make wheels that dont look like a bunch of soulsand glued together.

The sky is no longer safe.



Features

Variable Weight Copycats

Copycat blocks can now have different weights.

Some are super-light for flying machines.
Some are dense enough to turn your airship into a falling brick.

Perfect for:

  • Balancing aircraft
  • Counterweights
  • Lightweight hulls
  • Heavy armored builds
  • Questionable engineering decisions

Sticky Copycats

Blocks that grab onto nearby surfaces and entities.

Use them for:

  • ...questionable stuff

Slippery Copycats

Low-friction surfaces for maximum chaos.

Great for:

  • Sliding mechanisms
  • Conveyor-style movement
  • Ice-inspired builds
  • Runways
  • Watching players fail to stop in time

Floating Copycats

Blocks with levitite properties.

Build:

  • Floating structures
  • Experimental aircraft
  • Suspiciously physics-defying machines
  • Ships that probably should not fly

Fragile Copycats

Some blocks crack under stress.

Heavy impacts, bad engineering, or reckless flying may cause parts of your contraption to break apart.

Because realism is funny sometimes.


Designed For Create Aeronautics

This addon is built around and for Create Aeronautics, allowing copycat blocks to interact with flying contraptions in much more interesting ways than standard decoration blocks.

Your builds are no longer just cosmetic.
They are engineering problems.

Final Warning

If your airship explodes because you made the entire frame out of fragile copycats:

that is considered intended behavior and we do not take legal responsibility for that.
