Hello

Can somebody tell me what is the expression for a random x position between 5 and -5 from frame to frame?

Thank you

Yes, this is exactly what I looking for. Thank you very much. Is there any expression dictionary or something where I can learn the expressions from?

probably not dictionary, but if you bring up help (F1) then search for VEX, go to ‘using VEX expressions’…it's pretty good

There is an expression cookbook in the Houdini documents that contains some tips and tricks for writing expressions: http://www.sidefx.com/docs/houdini/ref/expression_cookbook.html [www.sidefx.com] You can also use help (F1) and search for ‘expression cookbook’
