Construct the Cycling Image for the Puzzle
| Create a unit-sized image to divide up into the puzzle.
The image cycles through four images upon toggleImage events. |
ImageBvr createUnitImageForPuzzle() {
| Create the different images that will be used in the puzzle: |
| time-varying solid-colored image for background |
ImageBvr bkgnd = createBackgroundColorCycler();
| image of time-varying elapsed time in seconds |
ImageBvr counterImg = createCounterImage();
| first possible image for puzzle, time over colored background |
ImageBvr unitIm1 = overlay(counterImg, bkgnd);
| second possibility, based on rendered geometry |
ImageBvr unitIm2 = createGeoImage();
| third possibility, based in imported video |
ImageBvr unitIm3 = createMovieImage();
| forth possibility, time in second over the video |
ImageBvr unitIm4 = overlay(counterImg, unitIm3);
| Have these image behaviors run just once, so
that they don't get restarted when events happen. |
unitIm1 = (ImageBvr)unitIm1.runOnce();
unitIm2 = (ImageBvr)unitIm2.runOnce();
unitIm3 = (ImageBvr)unitIm3.runOnce();
unitIm4 = (ImageBvr)unitIm4.runOnce();
| Cycle between the four images on occurence of this app event. |
ImageBvr imageToShow = ImageBvr.newUninitBvr();
_toggleImageUsed = new AppTriggeredEvent();
imageToShow.init( until(unitIm1,
_toggleImageUsed, until(unitIm2,
_toggleImageUsed, until(unitIm3,
_toggleImageUsed, until(unitIm4,
_toggleImageUsed, imageToShow)))));
return imageToShow;
