Gravity Yard First Principles
Cargo must arrive intact. But must every segment be powered? Rethink the old method using terrain and momentum.
The old route uses four powered segments. Get the cart to the right-hand door using terrain and momentum instead of motors.
You may change the old route, track types and power use. Model rules: 8 segments run left to right, starting speed 1. Gray blocks are forbidden track junctions.
Gold marks the segment being edited. Track numbers match the buttons below.
Try the old route to see where it violates a constraint, or edit immediately.
Which segment will you change?
Choose a segment, then its track. Editing is free and trials are repeatable. Later segments move vertically with earlier changes.
Track for segment 1
Speed is a discrete game measure, not kilometers per hour. Downhill gains speed; coasting spends it. Powered and lift tracks set the exit speed by the rules above.
