Gun/laser firing script?

Hello I found this script here http://www.the3dstudio.com/product_details.aspx?id_product=68453 that I dont think can be used in blender. Is there anything like it that allows easy shooting animations?

i would just use a particle system. I’ll try to upload a quick test blend file. i remember seeing something here about firing. i’ll try to dig it up.

Edit: http://blenderartists.org/forum/showthread.php?t=176066&highlight=spaceship+bullets here it is.
