Title: bug on low fps and play from frame?
Post by: drkucho on January 22, 2015, 03:23:46 am

i think i found a bug , i have a plant growing animation of 16 frames which goes very slow , i use PlayFromFrame with a random frame to start each plant on a different frame , but weird things happen when the clip fps starts to get smaller than 1 second

i have several instances of the same sprite with this code (startFrame is random each time, calculated before)

   anim.PlayFromFrame(startFrame);
   print ("START FRAME =" + startFrame + " ANIM FRAME =" + anim.CurrentFrame + " FPS=" + anim.ClipFps);

these are the results for different values of clip FPS assigned in the SpriteAnimator editor each time, i have marked the weird ones with <— ???!!! , as you can see, the issue seems to go crazier the more we go down on FPS, there is like a "threshold" that makes the animation to go the last frame instead of the right one.

The code suggests it should work fine, can you post a repro in private support or email? It should be obvious what is goign on when debugging this.
