# Increasing speed...

 11 November 2007 fabriciomicheli The real Dr. Gonzo   portfolio Fabricio Micheli Visual Artist Posadas, Argentina Increasing speed... Hi there guys. Let me tell you my problem. I have a torus knot object. I created a plow source and use the torus object as volume for my particles so I set the object as no renderable and I have the shape of the torus conformed by particles... well, it's ok so far... now the idea is that i want to disorder the particles from its original torus shape. For this, I want to increase the speed slowly so the particles move faster in order the movie goes forward. The problem is that taking into account that I created all the particles in the first frame, when I adjust the velocity or speed of the particles, nothing happens. I mean I want to start moving the particles slow and faster every frame from frame 20 forward, but I asume according to what I tried, that the particle speed is attached according to the moment on that particle was born. How can I accelerate particles that were born already and have an inicial speed value of zero? Hope you can help me my friends. __________________ "Anyone who has never made a mistake has never tried anything new." (Albert Einstein) ::::::::::::::::::::::: share quote

Set a key at frame 0 with a speed of 0 scrub to frame 20, set another key with a speed of 100. __________________ poof ~>Vimeo<~ Last edited by JohnnyRandom : 11 November 2007 at 06:26 PM.

 11 November 2007 fabriciomicheli The real Dr. Gonzo   portfolio Fabricio Micheli Visual Artist Posadas, Argentina I got that, but how can I link the age of a particle with speed? the idea is that, the older the particle, the faster it moves. __________________ "Anyone who has never made a mistake has never tried anything new."

I see. Oh dear, script it.

Sorry, I must have misunderstood your question.

Here is an attempt at it: it loops the particle through a spawn, each time the particle goes through the loop it gains 20+20% inhereted speed.

I think that scripting it would give you more control. __________________ poof ~>Vimeo<~ share quote
