scripting - What is the function to run simulation in MEL? -

-

i create mel script creates scene, setting ncloth , passive collider objects , run simulation frame.

in script editor, can see scene set-up there no function starting simulation.

technique @andreas suggests called "command harvesting". great way learn , how maya doing things. answer specific question:

you can use cmds.play() start playing on maya. see docs options.

you might want set start frame , end frame of playback range using cmds.playbackoptions() command. see docs options.

so do: (relevant explanatory comments added)

# egs. play frame 1 120 # note playbackspeed flag used # need set 0 "play every frame". # setting maxplaybackspeed 0 result in free playback, playback isn't clamped. # @ point, playback wouldn't realtime, accurate. # dynamics , simulations must played or nucleus not evaluate properly.  cmds.playbackoptions(animationstarttime=1, animationendtime=120, playbackspeed=0, maxplaybackspeed=0)  # start playback cmds.play(forward=true)

edit: noticed had asked mel commands. take above commands , mel-ify them, so:

playbackoptions -e animationstarttime 1 animationendtime 120 playbackspeed 0; play -f 1;

suggestion: best playblast playback watch in proper fps , playback speed.

hope useful.
