by Joseph Alotta 23 Sep '16

Greetings, The main program I am working on now is called Books. If I evaluate Books allInstances => anOrderedCollection( aBook aBook aBook ) How do I set them all equal to nil like Books removeAllInstances. Books allInstances => anOrderedCollection(). Sincerely, Joseph.

generating animations
by Ralph Boland 22 Sep '16

22 Sep '16

I am creating an educational computer game in Squeak in which I need to have animals (cats, dogs, birds, possibly other animals) move mostly horizontally across the screen. (Vertical motion is also possible but this would just be a bonus.) An animal will be in a square box (not sure if boxes will have a visible boundary) of sizes varying according to screen size. For a 1024x768 screen the boxes would be 13x13 pixels. For a 1920x1080 screen the boxes would be 24x24 pixesl. etc. The animations don't need to be great; adequate to entertain a child of age 4-10 yrs. I am not interested in animation per say and want to be able to write this code with a minimal amount of effort. Can anyone suggest where I can learn how to do this? If there is code that I can copy and modify that would be great. P.S. In the case of cats I am also in an animation of the cat turning itself right side up from upside down as it falls. P.P.S. Also neat would be of cats/dogs jumping up onto a ledge but this would just be a bonus. I am planning for the code to be open source and free. And pointers to code or documentation on how to write such code much appreciated. If any animators out there are interested in doing the animation part of my game please contact me. Thanks Ralph Boland rpboland(a)gmail.com

Expand TextMorph to encompass entire string?
by John-Reed Maffeo 09 Sep '16

Total Morphic newbie here - I am trying to build a simple app with two panes (BorderedRectangles), each pane contains a column of rows. Each row contains a String for a label and a TextMorph to contain data that I want to display and possibly edit. Some of the TextMorphs contain long strings which cause the parent pane to expand out past the boundaries of the SystemWindow which contains it. I can't figure out how to limit the width of the row and let the height of the TextMorph vary based on the size of its contents. Any suggestions? jrm
