Creating alians

            alians[z][x].aBody = new Object();
            alians[z][x].aWing = new Object();
            //generate the alians body
            alians[z][x].aBody.object = new THREE.Mesh(aGeometry, aMaterial);
            alians[z][x].aBody.object.position.set(2*x-10,0,2*z-30);//-3,0,0
            scene.add(alians[z][x].aBody.object);
            //generate the alians wing
            alians[z][x].aWing.object = new THREE.Mesh(aWingGeometry, aWingMaterial);
            alians[z][x].aWing.object.position.set(2*x-10,-1,2*z-30);//-3,-1,0
            scene.add(alians[z][x].aWing.object);
