Interface WorldQueryHitTestResultWearable Only

The result of the hitTest method call. This includes the world position of the hit, the world normal of the hit. Returns null if no intersection with environment was detected.

Example

// Set object's position and rotation if WorldQuery ray hits something.

onHitTestResult(result) {
    if (result === null) {
        // no hit detected
    } else {
        // get hit information
        const hitPosition = results.position;
        const hitNormal = results.normal;
        //identifying the direction the object should look at based on the normal of the hit location.

        var lookDirection;
        if (1 - Math.abs(hitNormal.normalize().dot(vec3.up())) < 0.01) {
            lookDirection = vec3.forward();
        } else {
            lookDirection = hitNormal.cross(vec3.up());
        }
        const toRotation = quat.lookAt(lookDirection, hitNormal);

        //set position and rotation

        this.targetObject.getTransform().setWorldPosition(hitPosition);
        this.targetObject.getTransform().setWorldRotation(toRotation);
    }
