View Full Version : Another Ball Bounce, Please Crit.

05 May 2008, 11:35 AM
I can see that this animation doesn't look quite right and I'll continue working on it today, but could you guys give me some ideas on what you think needs changing as well. I'm having a little trouble pinpointing everything.

Sorry, I'm an idiot, here it is...

Hi mattjmit,
I think your animation looks really good, the only thing I could point out,
as far as I'm qualified to do so, is that to me, the ball, right after the first
rebounce on the ground, look "pushed" by an unknown force or so...may it's
just the arc wich is a bit too wide or it's the second half of this particular arc,
there's a point where the balls feels like it's popping.
I hope i could explain what I mean, keep updating!:)

Good work so far! Yeah the second bounce(first on the ground) is picking up
speed. Also, there's a hell of alot of squash going on. Remember, even though
it's just a basic ball the same principle applies. Which is, what type of ball(or character)
is it? What's giving it it's initial velocity? What materials are the walls and floor
made of?

Might seem like I'm going a little too deep here, but see how this translates to
your more complicated animations down the track?

Hope it helps :)

thats not too far, thats the stuff I need, it a never ending road, so you can never overanalyse something as long as its in the right directsion, cheers for the help, ill apply it to my ball and see what happends.

Thanks teris, I had trouble with bouncing once it hit the ground, I'll keep going with that it was getting kind of unclear to me the more i watched it so its very helpfull to have some views from you guys.

I'd be carefull about applying too much of anything to
your ball (or balls), as this could result in a trip to the

we'll I'll definately take your advice on squash and stretch then

Apart from some speed issues on second bounce, the only major thing that concerns me is the volume consistency. I understand that it's 2d and it's not easy with tihs medium. But still keep practicing to maintain volume. Other than that great work!

In my experience, a bit of stretch is not too bad :)
I would stay away from squash though.

Hey flash, I definately agree about the volumes, I find it quite a struggle. I'm trying out a few tricks to help me with it, like always having the correct sized object on a seperate layer to check against. We'll see how it goes.

05 May 2008, 11:12 PM
Yes that's one trick we used to check the size against the original size in a separate drawing. I think's it's more about the practice that will train the eyes for volume consistency.

I think the other comments are valid. My only suggestion is not to use youtube for animation tests where you'd like comments on timing, as we cant scrub the frames. Maybe quicktime would be better?

I agree obraxis, I'm trying to figure out setting that up for next time I post.
