Droppable Behaviors in Etoys
by Steve Thomas 09 Feb '12

09 Feb '12

I am looking to create droppable behaviors similar to those in Lively Kernal. I can do it with connectors like this: > script1 > self getDestinationPlayer setColor: self getSourcePlayer getColor But would like to simply drop a morph onto another morph to accomplish the task. How can I get a list of morphs my "droppable behavior" is overlapping? Extra points for a sample project :) Thanks, Stephen

(I had never thought to look for the little spray can in the world's halo. Now I feel so dumb!) Now it will be much easier to make roads and racetracks. (Up to now, our slightly awkward method was to paint new objects, and then scale them up to suit.) Subbu mentioned the onion skin, and I just noticed that the selection tool for the rubber stamp sees partially through the onion skin and grabs a faded copy of whatever is under it. Is there a need for some kind of onion skin switch in the selection tool, that makes the skin either fully transparent or fully opaque? Have fun! David

What makes examples good for novices? and How do we tell if an example is good for novices?

So I am taking a P2PU course On How to Teach Web Programmin to Free Range Learners<http://p2pu.org/en/groups/how-to-teach-webcraft-and-programming-to-free-ran…>and a couple of questions came up: So I pose them to the community: 1. What makes examples good for novices? 2. How do we tell if an example is good for novices? Also where can I find a good set of examples for learning programming? It would be nice to have a curated set of "Great literature". Pointers to any research on the topic would be appreciated. Stephen

sixteen items for Squeakland 2012 - item 7: Single step debugger

A new project is attached for you to test and review. The new button looks like this: [image: StepMe.png] and the old one: [image: StepMe (bug).png] Of course, it's up to you to decide which form to use (or propose a new one). I don't really care much for the button's form anyway, but I'm *very* interested in the "stepping" feature. Cheers, Richo

If I create a text string which contains squeak code, how can I execute it from within a script?
by Steve Thomas 02 Feb '12

02 Feb '12

Folks, I am trying to create a project where kids can enter their own "Connector" functions. So what I want to do is given a connector connected to two text boxes (one Enhanced Text, so I can execute a script when they hit <CR> or on <focus loss>). I have a string variable defined for the connector, in which the kids can enter a function like ( D = S + 25) Where D maps to DestinationPlayer and S maps to SourcePlayer. Ideally I would like to generate the below script and execute it: doIt self getDestinationPlayer setNumericValue: self getSourcePlayer getNumericValue + 25 Need some squeak coding help on this. I guess specifically, assuming I can figure out how to create a string with the correct code ... How do I "do it" to the string? Thanks, Stephen
