[Newbies] Is there an easy way to implement an animation loop?
Hi there, I try to implement a blocking animation so that the process waits for the animation to be terminated before going ahead. This animation should lower the extent of a Morph in 20 iterations so that it looks like it would shrink. I tried to accomplish that in a '1 to: 20 do:' loop but the Morph is not updated during the iterations. I tried 'morph changed' but that doesn't work either. It does work, however, if I fork the animation loop. But than I have an extra process an need Semaphores to wait for its execution. That's not as simple as it could be. Is there any better way than fork and Semaphore? Maybe some force redraw method I have overlooked?

Re: [Newbies] Changing the extent of an ImageMorph
On 04.01.2012, at 16:44, Jan Teske wrote: Hey, I'm currently developing a small game with Squeak. Part of it is a bunch of menus which should have background images. Therefore I have realized them as ImageMorphs with the respective images. Now, there are menus which sizes are determined dynamically during the runtime of the game. That means I have to change the size of the menus. Since I cannot do this by manipulating 'menu extent: ...' directly, the only way I found until now is to manipulate the image form 'menu image: menu image scaledToSize: ...'. That works pretty well except for one thing: I cannot change the aspect ration of the original image with scaledToSize:. Since I do not know the extends of my menus before the game starts, I cannot say anything about the needed image ratio. Since my menus should be as applicable as possible I need to be able to resize also in a way which destroys the original scales. Is there any easy workaround for my problem or a recommended way for creating resizable Morphs with background images? Wouldn't it be simplest to just use a regular MenuMorph and give it a BitmapFillStyle?

Re: [Newbies] Is there an easy way to implement an animation loop?
Hi In morphich you should use the step method. Just add a step method to the morph and start the stepping when you want the animation to start. I think you must add a self changed or a self layoutChanged at the end of the step method to update the morph. It's a little more difficult to block all other morphs from update thou. But if they run animation, you can stop their stepping and start it again when your animation is done. Morphic runs in a single process and using other processes will not necessarily give trouble. You set the desired time between steps with method stepTime and return the millisecond time you would like.

Thank you, I will try it with stepping. Can you tell my what I have to do to prevent stepping as soon as the Morph is created? A 'morph stopStepping' in the initialize method is not helping since there is no world for the morph at this time. What shall I do instead? Thanks!

Re: [Newbies] Is there an easy way to implement an animation loop?
Ugh, that is right. Stepping starts right away for a new morph. Since you want stepping only at certain times you should use startSteppingSelector: and stopSteppingSelector: (and not call that selector/method #step.)

[Newbies] OpenGL integerated wtih Squeak IDE
This is a very poor attempt to do what Matt Fulmer did with OpenCobalt: integrate overlapping Morphic windows with OpenGL. The only advantage is that it doesn't require OpenCobalt. https://www.youtube.com/watch?v=Ctm-Q39nd-k The entire World is being rendered onto an OpenGL texture which is updated with every tick. With the proper scaling , the destop could be repositioned along the z access at any point within the fustrum and still keep the default mouse handling. Add mouse handling from OpenGL itself, and you can have 2D widgets projected onto 3D objects, not to mention 3D widgets fully integrated with the Squeak desktop. Time to revive/revitalize Balloon3D, perhaps? Whatever happened to 3D Morphic? There's obviously a great deal of room for optimization, and of course, the sky is the limit for what could be done in terms of lighting, materials, etc. Using more modern APIs of OpenGL (I'm using immediate mode! (!) and only stuff from the first 6 NeHe tutorials) one could have an awful lot of interesting stuff going on.
