    Hello everyone, I have several small shape 3d layers that I want to animate as if they had been shot by a catapult. I was wondering If anyone can help me with an expression to make the layers move and rotate randomly over time in the 3d space in order to avoid making keyfrmes for each transform parameter. thats all.

    You could try something like wiggle(#,#) or time*# on the rotation values, time would probably look more realistic, but I’m not sure, haven’t done something like that before.

    Hope it helps.

    Hey, actually you can watch the final result on the following link. I did this for the Ae Tuts+ Logo Reveal Contest so I uploaded it to youtube. You will see the characters of the logo being shot or impelled towards the camera. I only used the Time*# expression for the rotation of some of the characters and animated with keyframes the position values. It was not as time saving as I thought because tweaking the values of the expression to the desired look took some time. But is nice to learn a new experession since I don´t know too much about it.

    Here´s the link: https://www.youtube.com/watch?v=Kw9-Sa72_nI&feature=channel_page

    Thanks for the help again.
