Weird animation choppiness?

[J3sseM]

Hey guys!

I have asked this earlier, but it was old messy topic so I thought I'll ask again.

So, I have 60fps application and 60fps animation of legs walking.
I have created legs in Adobe After Effects, and it plays very smoothly when still and when moving around walking speed.

So the problem is that in MMF2 legs are quite choppy, shaking when walking.
I had to resize animation and scale to make it bigger again to make it fit in 1mb so I could upload example. <- it made the animation quite blurry so the problem is harder to spot, but it is there.

So, last time we had some brainstorm going on. I even tried this in Construct 2 to see if it's problem with MMF2. But same thing happened there also.

I think that After Effects moves the animation in sub-pixels, when MMF2 in whole pixels which could cause the problem.
If this is the case, could someone point me to a tutorial how to create easy sub-pixel movement? Do I need a shader for it or?

Thanks!

This problem often occurs in 3D-animation, it's usually called "foot sliding" and is present in 2D-animation whenever a cycle animation is in the game (walkcycle, runcycle).

Codewise a developer that does not use "delta" of timer is almost certain to experience timing issues, velocity issues and in cases animationspeed issues.

Here's an edited version where the code isn't the bottleneck.

Thanks tompa, gotta take a closer look what you did there.
Though I don't see it helping with shakiness, but maybe there is something there I did not notice.

Thanks!
