I’ve animated a cylinder moving along a straight line, with 2 location keyframes. After the second keyframe I would like the cylinder to continue moving in that direction at the same speed. Is there a quick way of doing this without working out the co-ordinates for it’s destination?
I was hoping I could achieve this with rigid body physics but gravity kicks in.
If I read your post right, what you’re looking for is a way of extrapolating. This is easily done:
In the Graph Editor (or the Dope Sheet, actually), select the channels you want (in this case, they’re you X, Y, and Z location channels) for your object
Press Shift+E and choose Linear Extrapolation (it’s in the menu, too, but I’m not able to look it up at the moment.
