I've been fighting that problem for a very long time. In fact, I'm actually having to come back to it yet again. I think this issue has appeared in the forums several times before with no resolution.
The jerkiness is quite real in the motion of the player. Entities placed on plats jerk severely (even worse than players do). It looks awful. I've looked at the code a number of times to get things to move smoothly with no luck. It seems that the BaseVelocity code which is supposed to help objects move on plats doesn't work very well. I'm not sure why. I'll try the smoothstairs trick to hide the problem for now, but I would rather get to the root of the problem instead of just masking it. It's interesting that the hl2mp seems to work ok. I haven't tried it myself, but it wouldn't be the first thing that works properly in hl2mp but not in the SDK. The weapon viewmodel skipping/jerkiness is another example. Incidently, it was suggested that the viewmodel problem be fixed by making the viewmodel code client-side only. I actually started to do this, but I then came to the conclusion that that solution was a major hack -- especially when essentially the same code seems to work with multiplayer version of the SDK, but not with the regular version of the SDK. I still don't know what the multiplayer version is doing differently to make the viewmodels work correctly. Finally, I wish that Valve would roll back their changes to the SDK tools. The latest version of the tools do not work properly. If you're not going to fix them, then at least go back to a version that did work. It's not nice doing unsolicited updates, installing broken code, then just leaving it that way. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
