Ball generators

Create marbles—any location, number, color, size or frequency.

Box generators

Create boxes -- just like marbles, a generator can produce any number, color, size or frequency.

Tracks & Conveyors

Tracks are frictionless and stationary. Conveyors move.

Killers

Destroy marbles and boxes. If marbles or boxes fall out of the world, they're destroyed. Use killers to remove them upon contact.

Motors

Lift marbles and boxes up. They work on straight and curved tracks. You can change how many are side-by-side, and space them out to your liking.

Motors are like the chains on the first big hill of a rollercoaster, adding potential energy to your scene. Use them to recylce the marbles and boxes you've already generated. Alternately, you can let marbles and boxes fall off your scene, or use killers to remove them. It's up to you.

Smooth/Rough

Conveyors and tracks can rise, fall and curve smoothly, run rigidly straight, or rest somewhere in between.

Stairstep Lifter

Stairstep lifters lift marbles higher in your scene. Marble Run Maker lets you choose how wide your lifter is, and how many steps it has. This is an easy way to lift large numbers of marbles higher in your scene.

Vertical Lifter

Vertical lifters lift more marbles higher in your scene. Marble Run Maker lets you choose how wide your lifter is, and how many steps it has, the spacing of the steps, and the dump direction. If the default vertical lifter doesn't meet your needs, you can build one yourself.

Copy

Press C (or click Copy) to create an exact duplicate of your selected objects. They will appear above the original.

You'll notice that most buttons have a hotkey in white. Once you learn these, you'll be free to keep your right hand on the mouse, and your left hand moving through the commands. This will let you create things very quickly.

In the videos below, we copy various objects the slow way (by clicking the buttons) and the fast way (by pressing the hotkey).
