Checkpoint Flag

A platformer checkpoint: a pole on a stone, metal or wooden base with a waving flag in any colour and a glowing finial. Active raises the flag to the top; inactive leaves a grey flag low on the pole. The cloth is two hinged parts, flag_0 at the pole and flag_1 at its middle, swaying about y (userData.tick, Loop clip baked). The base fits one 1 m grid cell; the whole piece is centred on its bounds, so the pole stands about 0.3 m left of the origin.

Passed the validator: real scale, rests on y = 0, front faces +Z, deterministic.

Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript
import { createAsset } from 'https://gaitkit.com/cdn/checkpoint-flag.mjs';

const checkpointFlag = createAsset();
scene.add(checkpointFlag);                      // rests on y = 0, front faces +Z

// 'flag_0' pivots on its hinge: -25° to 25° around y
checkpointFlag.getObjectByName('flag_0').rotation.y = THREE.MathUtils.degToRad(-25);

More in the docs; agents can fetch all of this through MCP.
