Mover on a spline - how to make it stop anywhere and resume ?


Recommended Posts

Apparently func_mover can only begin moving from the beginning of the spline and on stop, it gets reset to its starting position.


I am making something that has to be controlled from a GUI panel, and I need for func_mover to stop on the spline where I want, continue moving from that position, and not reset to the start position (which should be some bool spawn arg in the entity's def).


How can I fix that? (unless func_mover already does it by default and I just have no clue what I am doing :) )

I've not tried using splines. When you activate it does it stop, or does it just restart from the start without ever stopping? The code looks like it's meant to do the second one.


If I'm reading this right, this won't be a spawnarg fix. You'll have to amend the game code.


Activating a mover is set up to call idMover::Event_StartSpline() which is set up to restart the spline from its index 0, i.e. the start of its path. To change that I think you'd need 3 small changes:

  • activating it (idMover::Event_Activate) should check whether it's currently moving and call Event_StopSpline if so instead of always calling Event_StartSpline.
  • Event_StopSpline should store the current gameLocal.time so you know what time the mover got stopped
  • Event_StartSpline should use the stored time instead of spline->GetTime( 0 ) in the line: spline->ShiftTime( gameLocal.time - spline->GetTime( 0 ) ); so: spline->ShiftTime( gameLocal.time - stopTime );

Not tested of course but that looks like it'll start it up where it left off. You probably need to revert to using spline->GetTime( 0 ) if your stored stopTime hasn't yet been set: that's so it starts at the right point the first time you start it up, before you ever stop it.

      Say, I know it's been a while since the site got overhauled from the crash. But did we ever figure out if/how to get the recent topics & replies list back? It's not a total deal breaker but it was nice for becoming a thread creeper again...

      Some of you who've been on the TDM discord know I was out of work last Winter, just putting in hrs for the developer portfolio. Currently I've been working a seasonal job to pay the bills and now I'm finally in my last week before I get bumped off. Things will be tight but I'm planning a long off period to make as much content as I can. Big plans in Unreal Engine as well as my most ambitious TDM collab yet! Never been so excited to be a stuck at home to pursue my life's work. With a lotta time and maybe some luck, I'm hoping to get enough art work done that I may start applying around to studios.

      I finally got around to play Prey and I truly loved it. It is an incredible homage to System Shock and Deus Ex. While the gameplay is not en par with those two titles, the game makes up for that with its well written lore and story. The whole "world" just feells so authentic and it features a ton of really god environmental story-telling. Recommended for every immersive sim fan, i.e., everyone on this forum.
