Patch [#24763] NLA Track & Strip methods
Submitted by: Dan Eicher (dna) <quote> Adds: AnimData.nla_tracks.new(prev) * (optional) prev -- add new track after this track AnimData.nla_tracks.remove(track) AnimData.nla_tracks.active(track) * (optional) track -- track to set active * returns active track NlaTrack.strips.new(name, start, action) NOTE: fails if the strip can't fit in the track as opposed to the operator which will create a new track and add the strip to that. * name -- name for new strip * start -- start frame of new strip * action -- action to assign to strip NlaTrack.strips.remove(strip) </quote> --- I've resolved the issue (noted in the original patch) regarding the validation of the created strip by creating and using a "dummy AnimData" block to solve the missing dependencies.
