New release v0.5
SteveOW:
Thanks.
I can plot ellipse at an angle using Push/Translate/Rotate/fillEllipse, strokeEllispe/Pop.
But function Atan2 is not defined.

In the current build it is "Atn2"
I will either have to change the help file or the definition in the compiler.
Any preference?

Yah, that is how drawing of primitives is done in HTML5.
If you did not what to do that, there is always making a picture of an oval and then loading that as an image and use the image/sprite commands.
Glad to here you are making progress SteveOW.

I prefer "Atan2",
I can easilly revise my code to fit a later version of BB.
Just as matter of interest is there any technical reason why BB compiler couldnt handle both forms Atn2 and Atan2?
I know its not elegant, just asking. :)

Yes havent had as much spare time as I would have liked.
I'm not very experienced with sprites and images so will hold off on that for a bit.
I'm trying to de-confuse myself about rotation directions and signs at moment, always a challenge for me. ::)
Usually I just end up doing trial and error until it works right.
Suggest that future version of manual could benefit from a few details on how to use the functions Atan2/Atn2 and Rotate.
I know that any decent programmer should be able to work out the rules but it is a bit of a chore.
BB v0.5 is looking VERY GOOD. :)
I strongly recommend anyone else to give BB a try-out.
