Passed the validator: real scale, rests on y = 0, front faces +Z, deterministic, planted feet never slide past 1 mm.

Use it

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

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/battle-mech.mjs';
import { walker } from 'https://gaitkit.com/runtime/walk.mjs';

const battleMech = createAsset();
scene.add(battleMech);                      // rests on y = 0, front faces +Z
const gait = walker(battleMech, { ground: (x, z) => terrainHeight(x, z) });   // or omit ground for a flat floor

let dist = 0;
renderer.setAnimationLoop(() => {
  dist += speed * clock.getDelta();
  battleMech.position.z = dist;
  gait.poseAt(dist);                  // feet stay planted, at any frame rate
  renderer.render(scene, camera);
});

JSX

import { useMemo, useRef } from 'react';
import { useFrame } from '@react-three/fiber';
import { createAsset } from 'https://gaitkit.com/cdn/battle-mech.mjs';
import { walker } from 'https://gaitkit.com/runtime/walk.mjs';

export function BattleMech({ speed = 1 }) {
  const model = useMemo(() => createAsset(), []);
  const gait = useMemo(() => walker(model), [model]);
  const dist = useRef(0);
  useFrame((_, dt) => {
    dist.current += speed * dt;
    model.position.z = dist.current;
    gait.poseAt(dist.current);                  // feet stay planted, at any frame rate
  });
  return <primitive object={model} />;
}

GDScript

# Import battle-mech.glb (download below). It carries an in-place "Walk" animation.
@onready var anim: AnimationPlayer = $BattleMech/AnimationPlayer

func _physics_process(delta):
    velocity = transform.basis.z * speed
    move_and_slide()
    anim.play("Walk")
    anim.speed_scale = speed / 3.25   # Walk clip covers 3.25 m/s at 1x

// Import battle-mech.glb with glTFast (com.unity.cloud.gltfast).
animator.Play("Walk");
animator.speed = speed / 3.25   // Walk clip covers 3.25 m/s at 1x

Prompt

Use the gaitkit MCP server: get_variant({ "id": "battle-mech", "want": "default look" })
then place the result and walk it with walker() so the feet stay planted.

Knobs

Knob	Type	Values	Default	What it does
`armor`	choice	`olive` `steel` `desert` `night`	`olive`	Paint scheme: olive (military green, amber trim), steel (bare grey, red trim), desert (sand, blue trim), night (black with a red visor).
`weapons`	choice	`cannons` `gatling` `missiles`	`cannons`	What the forearms carry: cannons (one long barrel each), gatling (six-barrel rotary guns that spin as it walks), missiles (box launchers with tube faces).
`racks`	toggle	on / off	`true`	Missile racks on top of both shoulders. Off = a cleaner, lighter silhouette.
`size`	range	0.5 to 1.8, step 0.05	`1`	Uniform scale. 1 is about 5 m tall; 0.5 is a 2.5 m power-armour brawler; 1.8 is a 9 m giant.

Presets: front-line brawler {"armor":"steel","weapons":"gatling","racks":false} · desert artillery {"armor":"desert","weapons":"missiles","racks":true,"size":1.3} · night raider {"armor":"night","weapons":"cannons","racks":false,"size":0.9}
