You should do a fresh Bloc install, because it looks like you only updated Bloc from iceberg. Bloc depends on other projects such as Sparta or Beacon. About examples: gtExamples are not necessarily return instance of BlElement, it is a general all-purpose framework developed independently from Bloc. There are so many complains about absence of class comments, but no one reads them. Looks like it is easier to remove experimental examples completely :) [image: Inline images 1] BlSelectionExamples don't seem to support... selection ha ha Sorry, I don't understand

Here is how I see the behaviour of an infinite animation: - stop it when element is removed from the space - resume it when element is re-added to the space It means that some object should store that animation (an element?). What if element is not going to be re-added to the space? Should animation reference it target in a weak manner and remove itself when target is garbage collected? However, we also have target-less animations... There are too many possibilities, that is why I think it should be up to the user of infinite animation how to manage its lifecycle. We could create a factory of pre-configured infinite animations for most common lifecycles. Cheers, Alex

Because I wanted it to work just one minute :) I don't know, there is no explanation for that. Also, what is the lifetime of an infinite animation? It can only be stopped by sending #stop to it. It is infinite after all. Please note, that animation target is not necessary a visual element, so we can not stop animation when element is removed from the scene graph. It also means that animations are not bound to any specific space, that is why we must not stop animation when space is closed. Infinite animations are not used yet, so we can still find some smart heuristics for stopping. Do you have any particular use-case for animations? Cheers, Alex On 26 November 2017 at 05:23, Sean P.

Hi Sean, > How would one do e.g. a ticking clock in Bloc? I pushed a clock example to the #master branch (BlClockExample clock) Stepping mechanism can be implemented using infinite animation (stepping is nothing else than a special case of animation). Below is a definition of animation used to rotate second hand by 6 degrees every second. BlNumberTransition new onStepDo: [ :aSecond | secondHand transformDo: [ :aTransform | aTransform rotateBy: aSecond * self minuteRotationDelta - 90 ] ]; from: 0; to: 60; *by: 1;* duration: 1 minute The code above says that we should do a number transition from 0 to 60 by 1 (0,1,2,3,4,5,6,7...60) during 1 minute. On every step we rotate our second hand by appropriate angle in degrees. -90 is needed because clock hands start from Pi/2 radians on a unit circle. In the end we get the following animation: [image: Inline images 1] P.S. In attachment I also send a high quality video. Cheers, Alex On 25 November 2017 at 23:58, Sean P.
