new guy Posted August 11, 2011 Posted August 11, 2011 Hey everyone, Wondered if anyone knew how to create bouncing particles with collisions? For instance, I'm doing something with a ton of soccer balls and wanted a bunch of soccer balls to fall from the top of the screen, bounce off a logo in the middle and land on the floor. Make sense? I can't seem to figure it out. Not sure how to control them. I know this is a big one, but any input would be so appreciated. Attached is screenshot of something I did with After Effects, but I know our beloved A:M could produce much better results with greater control... I just know it! Also, I attached a video clip of what I mean. Notice how the balls bounce off the 3D text in the middle, then bounce and roll on the floor. Best to all! Shawn bouncing_particles.mp4 Quote
Paul Forwood Posted August 11, 2011 Posted August 11, 2011 A:M doesn't have 3D particles. You should look at using Newton physics. Quote
Hash Fellow robcat2075 Posted August 11, 2011 Hash Fellow Posted August 11, 2011 most particles can bounce. There is a bounce setting in their properties. For Sprites, turn Object Collisions ON and set Bounce to greater than zero. But if you need a soccer ball to roll, then a Newton simulation is more likely . Matt Campbell has done lots of Newton objects falling for his Little Caeser's spots. Quote
Fuchur Posted August 12, 2011 Posted August 12, 2011 A model using Newton Dynamics, combined with the plugin "Multiple Copies / Multiple Imports" should help you very much... See you *Fuhcur* Quote
jason1025 Posted August 12, 2011 Posted August 12, 2011 I want to compliment you. That looks really good so far. Its nice to see professional grade / studio grade work. Quote
Xtaz Posted August 12, 2011 Posted August 12, 2011 I did a quick test using newton .. render time 2 min 18 sec using FakeAO and multiple instances The soccer ball model can be found HERE ball.mov Quote
mtpeak2 Posted August 12, 2011 Posted August 12, 2011 Cool stuff, Marcos! Though they need a little more bounce. Quote
Xtaz Posted August 12, 2011 Posted August 12, 2011 Thx... I had few time to work on it... when I increased the "bounce", the interaction between balls was too fast... But.. Of curse the results can be much much better Quote
Hash Fellow robcat2075 Posted August 12, 2011 Hash Fellow Posted August 12, 2011 Thx... I had few time to work on it... when I increased the "bounce", the interaction between balls was too fast... Perhaps reducing gravity might solve that. Quote
Hash Fellow robcat2075 Posted August 12, 2011 Hash Fellow Posted August 12, 2011 I forgot... that looks real good Xtaz! Quote
John Bigboote Posted August 16, 2011 Posted August 16, 2011 Shawn- I took a little time today and played with some bouncing soccer balls (thanks Xtaz!) Take a look, if you fancy the .prj... it's YOURS! (I owe ya buddy!) -Matt RB_ballsfalls.mov Quote
John Bigboote Posted August 16, 2011 Posted August 16, 2011 You may notice at the beginning of the animation that the balls seem to interact with something... because they are! I find that if you simply drop multiple objects -they have no 'pre-orientation'... they are simply dead weights falling. But- if you give them something to interact WITH before entering frame they will have multiple trajectories, rotations and fall at random speeds. In this case, I have placed a 'funnel' above the scene... the funnel gives the balls a little 'how do you do' before they enter the scene... creating a more realistic result. It's good to be back from vacay... missed my Hashers! Quote
new guy Posted August 17, 2011 Author Posted August 17, 2011 I swear, every time I get on this forum, it makes me truly realize it's not the software, but the artist behind the software! When you combine absolute talent with awesome software (A:M) you get these results. Top notch work M.C. and Marcos! Quote
