Aeronautics: simulated copycats
by Multyfora
Aeronautics: simulated copycats gives Create copycat blocks different weights, friction and fragility, so contraptions built from them fly, land and break in distinct ways.
What it does
Copycat blocks in this mod carry physical properties such as weight, friction and fragility, and those properties change how a flying contraption behaves. Lightweight hulls help lighter-than-air builds stay aloft, dense blocks can drag an airship down, and some blocks crack under stress or break apart on heavy impacts. Sticky landing pads, ice-slick runways and low-friction surfaces change how a craft lands and slides.
The mod is built around Create Aeronautics and lets copycat blocks interact with flying contraptions in more ways than standard decoration blocks. Physical tires do not slip, big mechanical legs are available for walking machines, and fast-moving parts can be stopped. Its author describes the content as deliberately chaotic and accepts that airships can fall apart when built from fragile copycats.
The server and every player need the mod installed. It is open source under the GNU General Public License v3.0 or later, and it is published for NeoForge 1.21.1 only, with 1.3.2 as the latest file.
Key features
Weighted copycat blocks
Copycat blocks come in different weights, so a hull can be built light enough to fly or heavy enough to sink.
Surface friction
Blocks range from high-friction grips to slick surfaces, which affects landing, braking and sliding.
Fragile and cracking blocks
Some blocks crack under stress, and heavy impacts can make parts of a contraption break apart.
Mechanical legs and tires
Large mechanical legs and physical tires that do not slip extend what walking and rolling builds can do.

What the author says
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.
