Thanks Casper. Much appreciated. I'll test it now. :) ________________________________

However, it should be fairly easy to adapt the code to your liking. Basically what I do is letting the tween class calculate my path & timing, and on eachStep I move the map. On eachStep, you should move your pinpoint with something like this: (NOTE: not tested) someFunc: function() { // var fromCoord = your starting point // var toCoord = your destination point // var duration = number of steps it should take, the more you take, the smoother the ride & longer it will take. (unless you also change the INTERVAL constant on Tween) var callbacks = { eachStep: tweenstep }; var tween = new OpenLayers.Tween(OpenLayers.Easing.Quad.easeInOut); tween.start(fromCoord, toCoord, duration, {callbacks: callbacks} }, tweenstep: function (value) { // TODO: move your feature to the new coord // given in value.x and value.y }, And another note: the tweenstep function is being called from the tween class, so you are out of scope and cannot see your feature. That's why, in my blogpost, I also stored the map object into the tween. You will probably have to do something similar with your feature. If you can't get this to work, I might be able to set up a sample somewhere. Also, you might have some luck looking at the developer example code: http://openlayers.org/dev/tests/manual/tween.html regards, Casper On Wed, Dec 7, 2011 at 6:39 PM, Takako Tucker <[email protected]> wrote: Hi, so this is what I currently got. http://paste.org/41978 I can't seem to see Tweening working between pinpoints... Any advise would be much appreciated. The map shouldn't move and just pinpoints should move...

I had a look at .Tween, but as it reacts to DOM elements I couldn't be sure if it works with Lon Lat (X.Y) figure. I'll try again later on though. ________________________________ From: Adam Eskreis [mailto:[email protected]] Sent: 06 December 2011 18:03 To: Takako Tucker Cc: [email protected] Subject: Re: [OpenLayers-Users] Tweening pinpoints There is an OpenLayers.Tween class I believe. Also, this is something that could easily be done iwth just regular javascript. Don't forget, OpenLayers is comprised of DOM elements, so you can manipulate the map with regular javascript, you don't have to use an OpenLayers construct.

Has anyone done tween animation for moving pinpoints? Any advise would be much appreciated!
