Race against bots, nine new items, and wheels that steer

Bots

• New: /kart start --withBots fills the grid with computer drivers, or --withBots=N adds N. They drive the same karts with the same keys you have: they follow the racing line, drift through bends, trick off jumps, use their items and back out of what they hit. They place in the standings and show on the map, but never set a track record. Each is a mannequin in a matching helmet on Minecraft 1.21.9 and newer. Needs RP Engine 0.2.51. Permission gokarts.start.bots.

Items

• New: nine items: banana bunch, decoy box, bumper orb, storm drone, overdrive, hyper shield, smoke bomb, shockwave horn and static surge, each with odds by place in config.yml.
• New: /kart item <item> [player] hands a racer an item, for testing and events.
• New: Q scraps the item you hold so the next box gives you a fresh one. With empty hands, Q puts you back on the track only when you are off the road or stuck.
• The item in your hand is no longer drawn over the track.

Karts

• New: the front wheels and the steering wheel turn as you steer (RP Engine 0.2.51).
• The wheels roll with the kart at a speed that reads as rolling, and reversing no longer spins them forwards.
• Boosting puts out a black and white exhaust, and effects on a kart point the way it faces.
• An item box breaks on the kart, and bananas lie on the road.

Races

• Changed: races no longer start on their own. Staff start them with /kart start; race.auto-start: true brings the countdown back.
• Fixed: WRONG WAY flashing at the start or after a boost.
• A race everyone has left ends, and its boxes, bananas and rockets go with it. Whoever sat out a full grid goes first next time.
• Fixes to results, records, pads on prefab tracks, item boxes in unloaded chunks, and track commands running at the same time.
• The lap panel shows "Best -:--.--" until you finish a lap.
