is there a way to check if a gif finished the animation? the problem is that the gif is looping, and i want to remove it after it's over.

end of gif
Save the first image in a field. Use a boolean field to detect when that image is involved in a changing of images.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | // fieldsprivate boolean isFirstImage;private GreenfootImage firstImage;private GifImage gif = ...;// in actsetImage(gif.getCurrentImage()); // update imageif (firstImage == null) // initializing (only executed during first act step){ firstImage = getImage(); // retain first image isFirstImage = true; // set tracking field}if (isFirstImage != (getImage() == firstImage)) // if an image change involved first image{ isFirstImage = ! isFirstImage; // toggle tracking field if (isFirstImage) getWorld().removeObject(this); // if returning to first image, remove this} |
thank you so much! this also helped me understand better the usage of gifs in greenfoot.
