Созданные регистры в нодах просто исчезли, остались только стандартные R0, R1 и т.д. Пробовал включать Global - результата нет

спасибо за идею, но как-то совсем трудно это использовать: скорость должна изменяться плавно и в зависимости от текущей; с f-curve это всё работало автоматически

Для сглаживания перемещений использовал модуль time. Там есть функция animate, но она даёт прямолинейную зависимость от времени.

А версия бледнера 2-77 и адона версии 16-02 совместимы ? или ждать релиза 16-03?

So if i understand well. When i need to map a large area i could just check the X and Y of the mouse click and launch a function that would be more efficient than calling pick_object.
In the case for example where i have two navigation objects. If I use viewport alignement they would always be at the same place. so if i determine a max and min X and Y i could simplify my app by checking if i click in a zone on the screen rather than calling pick_object?
Of course it would need a bit of math to recalculate the desired zone according to the viewport size for every device or every time the viewport size changes.

Question. When i use the switchselect in the node tree : is it using pick_object under the hood?

I am not very confortable with JS in Blend4web so i copy past from different tutorial to meet my need. So the process is a bit slow.

But i wonder if i start an animation with the node tree can i stop it by calling a JS function?
I wouldn't be modifying the node tree behavior. I was thinking of looping a animation with the don't wait option. But to stop it within the node tree is going to be hell.
So could a stop animation be called from my JS file? Does it sound OK?
