* XXX: We send OnCommand on load, then we send no updates until we get
|
|
* StartTransitioning. Historically, this was fine, but it's incorrect now
|
|
* that commands can have arbitrary side-effects. We should only send OnCommand
|
|
* when we get StartTransitioning, but we need to run it early to set m_fLengthSeconds.
|
|
* Eventually, phase out GetLengthSeconds (ScreenGameplay is somewhat tricky). For
|
|
* now, play a "StartTransitioning" command; put anything that has side-effects in
|
|
* there, instead.
