void ClearPosition(JsonValue& entity)
void RotateByQuat(const float q[4], const float v[3], float out[3]): Rotate v by the unit quaternion q (x, y, z, w).

Function documentation

void ClearPosition(JsonValue& entity)

Take the position out of an entity's saved form ({"components": {...}}). A prefab is placed where it is spawned, so it is kept centred: rotation and scale stay, the scene offset goes.
