turtleart-activity's Introduction

TurtleBlocks

Turtle Art, also known as Turtle Blocks, is an activity with a Logo-inspired graphical "turtle" that draws colorful art based on snap-together visual programming elements. Its "low floor" provides an easy entry point for beginners. It also has "high ceiling" programming, graphics, mathematics, and Computer Science features which will challenge the more adventurous student.

.. note ::

There are two inter-compatible programs: Turtle Art and Turtle Blocks. Turtle Art, which closely parallels the Java version of Turtle Art maintained by Brian Silverman, offers a small subset of the functionality of Turtle Blocks. Turtle Blocks is the version included in the Sugar distribution. Sugar users probably want to use Turtle Blocks rather than Turtle Art. (Also see Turtle Confusion, a collection of programming challenges designed by Barry Newell.)

Using Turtle Art

Start by clicking on (or dragging) blocks from the Turtle palette. Use multiple blocks to create drawings; as the turtle moves under your control, colorful lines are drawn.

You add blocks to your program by clicking on or dragging them from the palette to the main area. You can delete a block by dragging it back onto the palette. Click anywhere on a "stack" of blocks to start executing that stack or by clicking in the Rabbit (fast) or Turtle (slow) on the Main Toolbar.

turtleart-activity's Issues

Collaboration: Players are able to move other's turtles

This shouldn't happen, and it may cause a mis-synchronization on both the sharer or joiner.

On the image above, the right is the joiner and the left is the sharer. The sharer is the one who moved the joiner's turtle (doesn't apply to the joiner).

buggggggggggdgsdsd

Help button error.

On clicking the help button the conosle shows the following error

  File "/home/guest/turtleart-activity/TurtleArt/util/helpbutton.py", line 76, in __help_button_clicked_cb
    self._palette.popup(immediate=True, state=1)
TypeError: popup() got an unexpected keyword argument 'state'

hollow line support

We have support for a "hollow line" in the JavaScript version of Turtle. It appears on the Pen Palette and implemented in the Turtle Painter code.

https://github.com/sugarlabs/musicblocks/blob/2d4f48bd62908ca16a8abe15742615270677a006/js/blocks/PenBlocks.js#L588

https://github.com/sugarlabs/musicblocks/blob/2d4f48bd62908ca16a8abe15742615270677a006/js/turtle-painter.js#L262

The block is really useful for 3-D printing, where you can directly extrude from the exported SVG using programs like TinkerCad.

Josh Burker has lots of fun lesson plans that use this feature:

See https://www.redalyc.org/pdf/547/54741184007.pdf

The goal here is to provide similar functionality to the Python code.

RuntimeError: sys.meta_path must be a list of import hooks, AttributeError: 'NoneType' object has no attribute 'SMALL_ICON_SIZE'

On Fedora 18 on an XO-4 with Sugar 0.112, the Turtle Blocks 218 logs this on stop;

Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/sugar3/logger.py", line 72, in _except_
    from IPython.ultraTB import AutoFormattedTB
RuntimeError: sys.meta_path must be a list of import hooks

Original exception was:

AttributeError: 'NoneType' object has no attribute 'SMALL_ICON_SIZE'

No apparent impact.

No other activities log this.

A bisection shows regression introduced by e3f8fa9 GTK3 and GST1.0 port.

v218 touch unresponsive and step mode hangs

On upgrade from v215 to v218, two problems observed by a teacher;

it is more difficult to use touch to deploy a block to the canvas,
step mode stops, and log contains errors.

Traceback when testing collaboration

I'm not sure what I triggered to have this error pop, but it's clear that it's trying to compare a string to an integer:

Traceback (most recent call last):
  File "/home/kiy4h/Activities/TortugadeMexico/TurtleArt/tacollaboration.py", line 133, in _message_cb

    if payload > 0:
TypeError: '>' not supported between instances of 'str' and 'int'

Ramp up or tutorial

A study found that the activity is rarely used to construct a working block set, so a ramp up or tutorial may be helpful for situations where no teacher or peer instruction is received.

Pi GPIO support

Let Raspberry Pi users read/write to GPIO. Not sure about the best approach (extension?).

Canvas drawn with black background

On Fedora 27 on Raspberry Pi 3, the canvas is drawn with a black background.

There are no unusual warnings.

Two po/*.pot files

There are two POT files in the repository.

Perhaps there should be one? I'm not sure; I know it is a complex activity with respect to the extras repository. No impact in my debian packaging or running the activity.

Fails to Start

Activity fails to start and this is seen in the logs.

as reported on flathub/org.laptop.TurtleArtActivity#5 (comment) , managed to reproduce myself.

One thing to note is it seems that clicking it the first time produces the error but going to another tab and then back to it works fine.

rename repo

Once the GTK3 branch is merged, we should rename this repo to activity-turtleart and remove the deprecated activity-turtleart-gtk3 repo

get_proprerty()

code on this line looks wrong;

turtleart-activity/TurtleArt/tagplay.py

Line 210 in 4bb1e8f

self.videowidget_xid = videowidget.get_proprerty('window').get_xid()

introduced by e3f8fa9

Suggestion: No delay when using the snail mode if the display doesn't change

It would be better when using the snail mode, blocks that doesn't cause the display to change doesn't delay.
Even better, if running the move/turn block with snail mode, the turtle smoothly glides/change direction.

What do you think?

-o command line option doesn't work

It's supposed to output .png of canvas.

I've gone back in git history and found it was working in v92 but no longer in v100.

Only a blank canvas is produced in current master branch.

turtleblocks.py should load same plugins as Sugar version by default

Try to load graphics-xo-child.ta from turtleblocks.py (gnome version). Some blocks don't appear and it will crash.

Python GI API version warnings

TurtleBlocks-216 on Fedora 27 warns about

GConf in TurtleActivity.py line 34,
PangoCairo in sprites.py line 86.

file selectors not working properly

The GTK file selectors (when running from cmd line outside of Sugar) seem to behaving properly from th UX POV, but they return empty filenames.

For example, the Save and Save As selectors don't work. The Export As Image selector also fails.

flake8 opportunities

About 8463 flake8 errors are generated by;

python2 -m flake8 $(find . -name '*.py') | wc --lines

Work can be broken down into main program, plugins, and others.

Change python2 to python3 once the activity has been ported.

Observed result: display does not use full screen, circles are drawn as lines. Like this;

Downgrading to 215 fixes both.
