I'm not actually doing a run/jump/run/jump/.. thingy. I just have a list
of animations, some of which repeat. Each character has a list of
animations.
I was experimenting to see if I could get something working. Currently I
have a very long run followed by a short jump (wrong). Plus the
animation takes 10 seconds to start.
I do have a skip animation to work on, maybe that's a bit of run and jump.
But not too high.
