I see a post by nXIII in the future of this thread.[/psychic]

I don't know. I'll look into it.

Ohhhhhhhhhhh yeaya! 
It's almost impossible for it not to happen.[/stupid]

Thanks! 

Mwhaha!

well, i guess your psychic mind was wrong. there's me instead. 

the easy way is probably to create a new method (and call it through the draw on) to add an ellipseMorph to the morph you're drawing using something that looks like

| circle |
circle _ EllipseMorph new.
circle extent: X@Y.
circle position: self position.
circle color: aColor.
self addMorph: circle

get it?

MUHAHAHAHAHAHAHA! ScratchReallyROCKS is psychic! 
To save a few characters, 20@20 is quicker than 20 asPoint. But I don't know why you'd want to save a few characters' typing. And also, I'm probably wrong as usual.

No, I think you're right, it just might be easier to change the radius (one place instead of two)

Uh oh... One more thing: It seems that the default bounds or whatever is called is something like 50@50... How do I change this?

super initialize. "THIS LINE IS VERY IMPORTANT!"

What does that do?

override #initialize to be something like this:

initialize
super initialize. "THIS LINE IS VERY IMPORTANT!"
self extent: 20@20. "Or something else."

Thanks!    In case you are wondering what this is for, I am making an iPhone app in Pharo Smalltalk.

in the World? What are you using to MAKE the pen drawings?

Yes, and... wait a second. Dang! I almost forgot that the Smalltalk pen trails are different than it's Scratch counterpart...    hmm...

This is what I am using for the orbiting algorithm (I am making my Scratch project, WhirlyGigs into an iPhone app with Smalltalk):

Code:

xPos := theta sin * 50.
            yPos := theta cos * 50.
            self position: xPos @ yPos.
            theta := theta + anInteger.
            (Delay forMilliseconds: 100) wait

vs the my project's algorithm. You can see it here.

So what are you using for pen trails?

I don't know now... I'll figure it out though. Thanks for all your help! 

I think Squeak has a built-in pen mechanism, the Pen class in the Graphics categories. The class has some testing/example methods for using it. Good luck!
