Look Ma! No Timer! // Interactive Artwork 1  |   Order by default Post by frootee // Apr 6, 2009, 4:24pm frootee Total Posts: 2667 Not sure if this will improve shared space animation performance or not but, I found a way to get scripted animation in shared space without a timer or paused activity loop. I guess it depends on what happens when several people show up in the same portal / server. Basically one object has a single keyframe; it does not have to move. That object is connected to a watchdog event. The Watchdog watches for changes. In this case, it is connected to an object's WldMatrix (the object with the keyframe). When we press the Animation Play button, at each frame, I suspect the WldMatrix connector of the object is invalidated (even though we have one keyframe). This causes the Watchdog event to 'trigger'. When the watchdog event triggers, we can connect the Control Out to a jscript command, to do whatever we want: move/rotate objects, amongst other things. I have a simple scene in the scriptorium: portal 1212 if you want to have a look. Press the animation Play button to see what happens. :) Change the animation End value on the timeline to extend the animation. Basically, the script command uses the RsTime.GetCurrentTime() function, which gets us the current time on the Timeline. But to get more generic, we can use the jscript 'time' type libraries to get the real world time instead.

Perhaps that's a question for the developers. Post by Wigand // Apr 10, 2009, 2:28am Wigand Total Posts: 462 I remember that I saw a script object without a timer working. It is in the examples library. It uses something like a infinite loop, or a feedback. The control out was connected to control in. I did not check the CPU load but it is an interesting idea. edit: I looked for and think it is the 'Dummy'-object of Pacman-scene Post by frootee // Apr 10, 2009, 3:55am frootee Total Posts: 2667 Thanks Wigand. That may be an Activity Loop, maybe with a Pause node as part of the loop. I tested that in shared space and it does seem to work better than a timer. the Dw: value (download) is about 50% less than when a Timer is used.
