I currently trying to remake the intro to Doctor Who, where a Tardis ( looks like a police box, think old school telephone booth) is spinning down a vortex.
What I’ve done is placed the tardis on a track so it moves down through the vortex.
On top of that I want it to be spinning as it goes down the track, so every five frames I rotated it very slighty on the z-axis.
But every now and then, instead of rotating on the z-axis the Tardis does a total flip!!!
I apologise if this question has been answered before, I couldn’t fine an answer when I was searching through the forum.
Here are some pictures to show you what I mean
