Copying and Pasting
Did you know that you can copy/paste stacks to/from the clipboard? You type Ctrl-C to copy whatever stack is under the cursor to the clipboard. Ctrl-V will paste from the clipboard onto whatever TA project you have open. Try pasting this code into your Turtle Art project.
[[0, "clean", 258, 217, [12, 1]], [1, "repeat", 258, 251, [0, 2, 3, null]], [2, ["number", 36], 309, 251, [1, null]], [3, "repeat", 323, 311, [1, 4, 5, 9]], [4, ["number", 4], 374, 311, [3, null]], [5, "forward", 388, 371, [3, 6, 7]], [6, ["number", 300], 459, 371, [5, null]], [7, "right", 388, 413, [5, 8, null]], [8, ["number", 90], 446, 413, [7, null]], [9, ["vspace", 20], 323, 389, [3, 10]], [10, "right", 323, 463, [9, 11, null]], [11, ["number", 10], 381, 463, [10, null]], [12, "start", 258, 175, [null, 0]]]
You can also paste text from the clipboard into text blocks.
Note: You can duplicate individual blocks with copy and paste, when duplicating a text block, deselect the text block after copying if you want to duplicate the block rather than duplicating the text within the block.
Speed
Turtle Art has three 'run' buttons:
- The 'rabbit' button will run your program at full screen. Note: It will highlight blocks during execution, so your program will run much faster if you hide blocks.
- The 'turtle' button will run your program with a slight delay between blocks. Block are highlighted as they are executed and block labels are updated with the current block values.
- The 'debug' button will run your program with a longer delay between blocks. Block are highlighted as they are executed and block labels are updated with the current block values.
Sharing
Turtle Art supports a simple sharing model. Whomever joins a shared activity will share turtles with the other participants, e.g., whatever any turtle draws will appear on every screen. Share can consume a lot of network bandwidth, so it is not recommended to share among more than 2–3 people at a time if the screen is frequently changing. As with all Sugar activities, you can use the Share-with feature of the Journal to share your Turtle Art projects with others.
Note: as of Version 83, Turtle Art will not share correctly with older versions.
Note: as of Version 106, Turtle Art will share between Sugar and GNOME.
Running Turtle Art outsde of Sugar
Turtle Art can be run in the GNOME desktop outside of Sugar.
PC HARDWARE:
- Download Turtle Art (as a *.xo archive)
- Extract the TurtleArt.activity directory from the archive, eg drag it to the desktop
- Open directory TurtleArt.activity
- Run turtleart.py (run in terminal is better, you can see error messages there)
OLPC XO HARDWARE
- The XO1.5 and later software builds for the XO1.0 allow switching between Gnome and Sugar desktops. The following assumes that Turtle Art is already installed in Sugar.
- Switch to the Gnome desktop
- open olpc's home on the desktop
- open Activities
- on later software builds, Activities is both hidden and locked, if so, check show hidden files to unhide, in terminal chmod 777 Activities to unlock
- open TurtleArt.activity
- run turtleart.py (run in terminal is better, you can see error messages there)
