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

Hi there,<br>
<br>
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.<br>
<br>
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.<br>
<br>
Is there any better way than fork and Semaphore? Maybe some force redraw method I have overlooked?<br>
<br>
Thanks in advance!<br>
