how to move only incorrect drag images?
August 9, 2007 12:00 AM
Hi,Another question regarding drag and drop images: I've made a drag and drop question where the important thing is that you choose the correct items to drag, and not where you drag them to. When the user checks his answer, the correct items seems to be left where they were put (this is actually new images), and the wrong items are moved back to their original spots. The correct items are actually also moved back, but covered by white rectangles. The problem now is to prevent the user from dropping new items to a spot that has already "been taken". Any ideas? I'll try to explain a little more, if this didn't make sense...:I have a task where the user is supposed to identify his company's 3 core values out of 6 values, and move them to 3 white spots on a dropimage:Let's say the user picks 2 correct values, and 1 wrong, and push the button "check answer". I now show two extra "fake" images on the drop-spots where the correct values where put. The "real" correct drag images are moved back to theire original spots, but covered by white rectangles. Also the wrong value is moved back, but is not covered. For the user this looks like only one of the white spots remains. The user tries again, and this time he picks the last correct value. He drags the item over to the drop image, but accidently tries to drop it on top of one of the spots where a correct answer is already showing. Ooops... This is actually possible, even though I have the "fake" image showing there!So.. How can I prevent this? I tried to put transparent rectangles on top of correct answers, but this didn't work.
