   Hello Richard Lord and community. I have a problem
   
   i want a make a "letters spray can", i was thinking about use a collada model then attach the letters spray but i dont know who to do it because this time im using classes.
   
   when i use particles i just add particles to a ColladaNode like this
   
   particles = new Particles();
   ColladaBase.addChild(particles);
   
   this is my code, this code just trow a letters spray. feel free to use or edit
