I recently found a great freely disturbuted fire generator for flash and I wanted to use it in my current project.

There was some crazy code I have never seen before, I have figured most of it out but I still have some issues with a few of the oporators I am not familiar with.

for example:

perlinValid &&= (value == \_distortionScale);

what does &&= mean?

and the other question was

super.height = value|0;

what does the | mean?

ive never seen &&= but i assume it means  
if perlinValid & it equals true and value equals \_distorionscale

super.height = value (or if value = null or undefined or false)then =0

Thank you Very much

I am still pretty new to classes and it is intuitive but I am having a hard time absorbing it all and making a useful connection to my timeline
