Hang gliders, elevators, tanks, graves, a chest with legs, and a crane you strap on. OpenCubes is the OpenBlocks toolbox, for modern Minecraft versions.

Written for NeoForge, from the old ideas.

Getting around

Stand on an elevator and jump to go up, sneak to go down. Fans throw you across a gap. A sleeping bag lets you pass the night anywhere, and your spawn point stays where it was. The hang glider rides thermals. The thermal elytra does the same thing on vanilla wings.

Building

The building guide ghosts in the blocks of a shape so you can follow them. Village highlighters trace the edge of a village. Sky blocks are windows with the weather behind them. Sketch blocks with a pencil that only you can see, then hand out glasses if you want anyone else in on it. There's paint, a drawing table and canvas when the walls are the problem.

Machines

Tanks hold fluids, liquid XP included. Drain it, shower in it, or stand on a healer and spend it. Vacuum hoppers pull in items and XP. Auto anvils and auto enchanting tables run once you feed them. Aim the item cannon and it fires stacks out of a chest. Sprinklers water the crops.

The other half

Die, and your inventory waits in a grave. The luggage follows you and eats whatever you drop. Get it struck by lightning and it holds twice as much. The crane on your back picks blocks up from across the room. A golden egg hatches into a small copy of you. Mobs you kill can drop a trophy: place it and right-click, and the chicken lays an egg while the creeper hisses. Bear traps, sponges that drink lava, sonic glasses and a cursor are in the same tab.

Mob trophies

Craft a book with a clay ball for the guide. It's called World Domination, and it needs Patchouli. JEI, Jade and Curios are picked up if you already have them.
