  • Possible to set the starting rotation when following a motion path?

    Posted by Brian Dunning on March 6, 2017 at 3:32 pm

    I have my object correctly following a motion path, and “Snap Alignment to Motion” is set and working — except my object is pointing the wrong way. Think of a race car driving sideways around a track, always 90 degrees off its direction of motion. I can’t seem to find a way to calibrate the rotation angle dictated by Snap Alignment to Motion. Is there a way to do this?

    Simply swap the Axis of the Snap Alignment Behavior from Horizontal to Vertical.

    My bad, I shouldn’t have said 90 degrees, because it’s some random angle. Neither horizontal nor vertical gives me the correct angle. I need finer control than that, I’d say it’s off by about 60 degrees. Thanks for your speedy reply though. 🙂

    I am currently hacking this by rotating the sprites in Photoshop and re-importing them. Does the job in a one-off way, but it’s a hack. Since there are multiple motion paths and I want it pointing different ways as it travels, I have to make a different file for each. Not the end of the world.

    That sounds curious.

    But the easy solution is to put your “racing car” into a group and apply the Motion Path and Snap Alignment to the group.

    Then you can adjust the rotation of the “racing car” layer to taste.

    Oooohhhhh — now I feel like an idiot for not thinking of that. Thanks, does the trick. 🙂
