Hi Sergio,

 

Unfortunately, since the trajectory is departed into time sections, also a noplay section currently covers a range of frames. You can probably overcome this by just repeating the desired frame, so you do not have to use a noplay section, or eventually use the morph.tcl script, that allows to create a morph from one to another structure so that the transition can be smoothed a little bit. I’m not totally sure if it would make sense to change something to the current behavior of noplay sections, what do you think? Also, you can of course make severel parts of the video and put them together later with a video editor.

 

Please let me know your opinions on that.

Betreff: vmd-l: Userani.tcl script jumps frame after no play

 

Dear vmd comunity,

I have made an script to do a userani.tcl animation and I find this problem. The video plays some frames moving forward in the trajectory, then there is a section with -noplay (a rotation) and then the trajectory continues. A part of the code is below and the full script is attached to the email:

#Kickoff really
   add_section kickoff2 -after kickoff -shiftend 150 -step 1 #no end means 1 frame + 10%
   add_eval kickoff2 dummy ;

   add_section topview -after kickoff2 -shiftend 150 -noplay
   add_eval topview dummy
   add_userani topview rotate x 90
   add_userani topview FadeTransparency AOChalky2 1.0 0.0 ;

   add_section ShowOs -after topview -shiftend 350 -step 1
   add_eval ShowOs dummy

When the ShowOs section start the trajectory makes a 150 step jump forward as if the -noplay section had not happened. Is there a way to solve this? Am I doing something wrong? It seems to make sense that after a no play section the frame would be the first of the no play section.

Thank you very much in advance!

Best regards,

Sergio Pérez-Conesa
