Hi aliaksei
I would love to start to play with Bloc to build a game with boxes.
Now is there any tutorial that I can follow to get started?
Stef
We could try to do it together and maybe even make a
video (stream) of
implementation process :)
Cheers,
Alex

Hi Peter
Exactly :) Lines are just bloc elements as anything else: buttons, text
images. They can be linear, can be arcs or bezier curves (both
quadratic or cubic). Default canvas used for rendering in >>Bloc
(SpartaCanvas) has very good support of vector shapes and lines.
It is very doable. Please, don't forget that Bloc is a low level
framework that does not contain any widgets (existing ones will be
deleted, especially BlLine, BlText and BlTextElement). The only

for your interest :)

Api itself is in "final" state, however naming might be improved
(changed with or without depreciations). But don't worry user-side api
is already in a very good shape, at least from our >>perspective :)

infrastructure that
does not put any constraints on users. Which means that if
you want to
have a bezier line you have to subclass BlElement, >>implement
corresponding accessors for anchor points and override
drawPathOnSpartaCanvas: in order to display you line. You can learn
more about canvas by checking SpartaCanvas class >>comment and method
comments in 'api' protocol.
Layouts, alignment, transformations are part of bloc and are available
to all subclasses of BlElement.

Alex

The idea for me is to make a simple mindmap
- elements with some text, icons, math symbols inside
- connectors (non-straight lines) between elements
To me (apart from the lines) it seems like it should be already doable.
Also either my (Morphic) Pharo is really slow, or Bloc (in the video)
is superfast (everything is happening instantly).
Thanks,
Peter
