Swobu
johnar:
Hi NoobJens007
That's a cool short animation. well done. hope to see more.
In reference to the cans staying still, until swobu hits them, and deleting the first key.
That is defineately an option, and the reason behind the unwanted movement, tho i think the way i would control it would be different.
On the frame immediately before a can moves, it should have a position and orientation key set.
Simply copy those keys and paste into the frame immediately before that frame, so you have the 2 frames keyed identically. Then zip back to where that object was last keyed, (in this case frame 0 (?) ), and paste those copied keys there as well. (into frame 0 and 1)
note. this is assuming the last time the objects position or orientation keys were set, was frame 0. (automatically).
One advantage in double keying like this, is that as your animations get longer, or more intricate, its a sure fire way of stopping any unwanted movement, in all situations.
For example, if swobu was to 'stack' the cans before knocking them over, the steps woud be:(for 1 can).
1) in frame 0, place the can in it's position before swobu picks it up. Add a key for position and orientation. Copy those keys and paste into frame 1.
2) copy both frames, (shift and click to select multiple frames), and paste into the 2 frames immediately before he picks the can up.
3) when he has put the can into position, do the same thing. Make sure position and orientation are keyed in that frame, and copy them into the frame next door. this will hold the can firmly there until the can is about to move again.(till swobu hits it)
4) when the can is ready to move, copy those last 2 frames into. the 2 frames immediately preceeding the can moving. (the bat hitting it)
5) when the can stops moving, key the final position and orientation into the last frame of movement and copy those keys into the frame next door, to bring the can to a dead stop again.
Once you get into the habit of double keying like this, (double key before start of motion, and double key at end of motion) it does become really easy, and really effective.
Having double keys can also help visually in the time track, making it easier to see stops and starts in motion. This can be really handy, especially when you want your cans to move completely individually. (timing etc..)
Claude:
If you want the position of the object to be fixed on
the left of the key,why not make the key a corner one
and using the key left handle in the graph editor make the curve flat?
N.B Probably need to adjust the first key too.
Update:yes you have to.

Hi Claude
Yes, thats the normal way to do it.
Double keying is just a habit i've picked up which, to me anyway, has advantages over using a single corner key, and actually, the visual part of seeing 2 keys side by side in the timetrack is one fairly main advantage, making it easier to quickly see in the time track where things stop and start. (different colored keys would do the same)
Double keying, for me, actually came about initially when wanting to STOP a motion. (Stop drifting). From there, it became quicker to copy those keys and paste them before re-starting a move, than it was to set a corner key. Tho i still do that at times.
Edit: Just to say, i'm not suggesting that different coloured keys would be a good thing.........hadn't really thought about that...

Thank you very much guys for the help!!

Double-keying.. certainly interesting. I haven't done quite enough animtion to say much about that but i think that's something I ended up finding out I needed to to to get things to be stable and not slightly "wiggle" backwards before moving in Anim8or, lol!!
@NoobJens007, something that could always be improved (especially amongst Anim8or users, as we're so caught up with making decent looking characters that we don't think about it) is the camerawork, making the camera move in a way that feels natural and stuff. I think the double-keying method from johnar can help here too haha!
