i suggest you including this code snipet in the original code to experience, cliking right mouse button, a first plane masive esplosion serie:

Code:
var Piloto_Masiva = 0;
function Explosion_Masiva ()
{
	var i;
	if ( Piloto_Masiva ) return;
	Piloto_Masiva = 1;
	while ( mouse_right )
	{
		vec_set ( POSICION, vector(random(300)-150,random(300)-150,0));
		Crear_Explosion ();
		wait(-0.2);
	}
	Piloto_Masiva = 0;
}

function main ()
{
	...
	on_mouse_right = Explosion_Masiva;
	...
}


thx all!!
