Message-ID: I believe that Melanie?s suggestion is the best one. Markers, both camera and object, were not designed to be moveable during runtime, only in the Scene setup. The metaphor Alice is using is that of markers or ?spikes? used in theatrical productions, which once set, should not be moved during the show. If a marker is needed at another location, create a new marker. Melanie is suggesting the creation of a virtual ?rig? that is attached the camera to the character or vehicle. 1. Position the camera in its relative position to the character. 2. Add the object that will serve as the ?rig? to the Scene. (We have found that the axes, found in the Shapes Gallery works well for this purpose.) 3. Move and Orient the rig object to the camera. 4. Set the Vehicle property of the rig object to the character. 5. Set the Opacity property of the rig object to 0.0. Let me know if you have any questions.

Message-ID: <94f817bd-555c-421a-88bd-8a3afaf48205@Spark> In the IDE, negative values for the resize* and setHeight|Width|Depth throw an exception that is logged and the operation is basically skipped, taking no animation time. On export to the player, we have different behavior. The set* methods and resize both accept negative values and produce the effect you are seeing, while the resizeHeight|Width|Depth log an error with each frame, and take up the animation time, unlike in the IDE. I have not done a full exploration of the effects of the various extra parameters. The difference in behavior after an error in the IDE and the Player is a known bug. The sizing behavior for negative numbers is a new one. I will add it to our list.

Looking at the code, both in this project and in Alice, I can't see where a negative value would come from. It has not happened on my machine, so diagnosis is more difficult. I am wondering if there is an error in the animation logic that is somehow overshooting the target value. (I am kind of grasping at straws, but this code is complex enough to be suspect.) Is there anything you can say about the machines where the problem is seen? What OS are they running? Are they especially underpowered or overworked? Experiments you might try, if you are so inclined: - Have the ogres say the size they being set to and see if that matches you see. - Change the resize duration to 0, to bypass the animation logic and see if it still happens. Wish I could provide a clear answer for you. Hopefully we can eventually. -Daniel Abeshouse Alice Project > On Apr 29, 2022, at 3:15 PM, Carlos Bovell via alice-teachers wrote: > > Hi, > > Here's the project we wrote that gives us upside down ogres.
