Re: Recording user actions in the RevMedia IDE
Trevor Devore has a framework and some ideas for the implementation of multiple undo in his "Application Framework" http://www.bluemangolearning.com/revolution/software/libraries/glx-application-framework/ - Stephen Barncard San Francisco http://houseofcubes.com/disco.irev 2009/12/16 Alejandro Tejada > > Hi all, > > Last Monday, i took three hours showing > RevMedia to some teachers. > > Besides the interface shock and the unique > need to name each object that you create, > it was the lack of multiple undo that raised > most eyebrows. > > If you want experiment, then how could you > recover your work if you lose it? > > Other programs, make this is possible with > multiple undo.

Re: Recording user actions
Thanks for this comprehensive suggestion. Sounds like it could work. I'll give it a try. Richard On Feb 20, 2005, at 12:02 AM, J.

You could try writing a mousemove handler (or a "send in " handler) that repeatedly checks the current tool, and if it is a drawing tool then have it store the mouse location every so many milliseconds, along with the currentTime of the QT movie, the current tool, and whatever else you need (pen color, linewidth, etc.) If the user changes drawing tools or creates a new object, add a blank line to the list you are creating. The list could be stored in a custom property. Then for playback, you'd create a single polygon object. Read the list one line at a time and compare the movie time stored there to the currentTime of the movie that is playing. If the times match, set the points of the polygon to the set of recorded points that have been accumulated up to then. You can use a single polygon object to simulate any number of drawn objects on screen. An empty line in the object's points list will cause the pen to "lift" and then set down again, effectively creating a new visual object. That's why your recorded list of points should include a blank line each time the original user changes tools or creates a new object. -- Jacqueline Landman Gay | [EMAIL PROTECTED] HyperActive Software | http://www.hyperactivesw.com ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

RE: Recording user actions
Following this undo madness... You can use a card script that records mousedown events, put them in an array using the seconds as array key and save that. The target, or shape type, it's position is also easy to save. To transfer the information you can either create a blank stack with the array as a custom property or create an xml or readeable output to read for the replay. Filter the "mouse" keywords in the revdocs to see the possibilities. Drag is also possible... As to the best method for event polling... i'll leave that to others - i usually rely on mousedown, repeat while mouse is down, mouseleave... and the target in a card script. cheers Xavier > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Richard Miller > Sent: Saturday, February 19, 2005 14:13 > To: How to use Revolution > Subject: Recording user actions > > Not sure of the best way to do this.
