Finish object logo #21
Comments
Note that this is being worked on in the fork: https://github.com/pahihu/ucblogo-code |
A lot of these problems have been fixed thanks to @pahihu The configure script now has a The manual does not mention things like So, besides the manual, is there anything else that needs to be fixed to close this bug? |
Just make sure USUAL works. The canonical example is make "double-turtle kindof turtle make "dashed.turtle kindof turtle make "turtle1 (oneof :double.turtle :dashed.turtle) make "turtle2 (oneof :dashed.turtle :double.turtle) What should happen is that they both move 200 steps, but turtle1 does 20 length-5 dashes while turtle2 does 10 length-10 dashes. If this all actually works I'll add the object primitives to the manual. I'll just copy the ones from the Object Logo manual. Pretty sure I wrote that section anyway... :) Oh this depends on having turtles as a primitive object class. Is that implemented? I'll try reading the code. |
Hi,
The canonical example didn’t worked.
I have changed the USUAL implementation, and now it works as expected.
Pushed the changes to GitHub.
I have attached the working Logo code and the example screenshot.

@pahihu Thanks, I made a merge request out of it. |
Hi,
I’ve made a simple Turtle class in Object Logo, so you can actually have multiple turtles.
The code is attached.

So, I realized later that there's no TURTLE primitive because ucblogo doesn't have multiple turtles. There's actually a whole bunch of "system objects" in Object Logo, at least some of which might be interesting. See attached chart. Files, turtles, windows, menus, menu items are things it would be great to have in version 7.0. Maybe I can throw some students at that.
