Copio todo el código para que se entienda. 
	Para probarlo simplemente se puede poner MaxDistance en un edificio y al colocarlo tira un warning.
 
if (this.template.Distance.MaxDistance)
{
  var dist = +this.template.Distance.MaxDistance;
  var nearEnts = cmpRangeManager.ExecuteQuery(this.entity, 0, dist, [cmpPlayer.GetPlayerID()], IID_BuildRestrictions).filter(filter);
  if (!nearEnts.length)
  {
    var result = markForPluralTranslation(
    "%(name)s too far from a %(category)s, must be within %(distance)s meter",
    "%(name)s too far from a %(category)s, must be within %(distance)s meters",
    +this.template.Distance.MinDistance);                                             // <---- This line
    result.success = false;
    result.translateMessage = true;
    result.parameters = {
      "name": name,
      "category": cat,
      "distance": this.template.Distance.MaxDistance
    };
    result.translateParameters = ["name", "category"];
    return result;	// Fail
  }
}
