If your a Vixen user then you will know there has been a massive amount of activity and builds being created. This is all the work that has been getting developed over the past 6 months or more. If you are one of those members that use the Dev builds then you may just want to wait a week or you will be installing a new build multiple times a day. There is still more effects to be added including a new Pin wheel effect. Also as per Jon's post below: I know I've said several times that we didn't think we would get this done in time for release. But things have been going too smoothly with this functionality and it looks like it will make its initial appearance in the coming release. That's not to say however that it will be 100% done. So, to recap, location based effects is a way to make effects apply to elements based on where they are located as opposed to how they are organized into groups. It can produce the same net result as what whole house models do in xlights. But like most other things, we're doing it a bit differently. We tried at first to use a similar methodology to what xlights is doing, it would afterall be more universal and easier to implement. However, it didn't work out well. Performance was shall we say, less than impressive. So Jeff went back to the drawing board and reimagined how it should work. (This is less than 2 weeks ago). What came back is a far more efficient method. Perhaps even more responsive than the current position based targeting. The down side is that each effect needs to be adjusted to make use of the new method. So as of now, the framework under the hood is done and ready, and 3 effects have been updated to include and show off this functionality. Barring any major bugs, this work will all be merged into the dev builds very soon and will be in the release soon. As to when other effects will be tweaked to use it, that remains to be seen. We'll get to it as the need dictates and time permits. Some effects may change to be only be location based. Others may not get it at all. And some may have both options. It all depends what the effect does and what makes sense in each case. Initially the effects that will have the location is Bar, color wash and butterfly. Jeff and I will work on the remain effects that can make use of it when time permits. Maybe the next update after the release. The release should be very soon.
