getting color from Velocity (or getting float?)
Sep 13th, 2009, 1:57pm  
Hello,
I have some question marks in my mind so i am going to wait for your precious helps, thanks for your time already.

So i got this particle class, and in display function there is point();
and some PVectors such as vel, loc, acc.

What i want to do is, making my particles a little red and white according to their Velocity. (when they move at >= specific speed) Though, since it is PVector i cannot get a float value from it, and i am stuck, don't know what to do in stroke(   );

Any suggestions to convert them to float, or get their value somehow?

Thank you,
metin

you can use vel.x vel.y vel.z to get what is stored in the PVector, in this case velocity in the different directions.

you can also temp store them in an array using http://processing.org/reference/PVector_array_.html
