| Right now, when you flip two cards over and don't make a match, they instantly flip back. It's so fast, you hardly have enough time to see what the second card was. In this section you'll add a simple timing mechanism to the game loop that will pause the rotation for half a second before the cards flip back. 1. | Open your copy of the memory game from your project_four folder. Right-click the 3D sprite and select Script from the context menu. Add the following property declaration at the top of the script: property flipPause | 2. | In the enterFrame handler, initialize flipPause within the same block of code that executes when a match is not made. This is the block of code that sets up the two transformobjects. You can add the code right after the line that sets transformPercent to 0: flipPause = _system.milliseconds + 500 This sets flipPause to half a second later than the current time. | 3. | Add the following conditional test immediately after the line that checks if isRotating is equal to 2, and immediately before the two lines that interpolate the two cards: if _system.milliseconds > flipPause then | 4. | Finally, add an end if statement to the end of the enterFrame handler, to close the timing test conditional statement. For reference, the enterFrame handler should now look like this: on enterFrame me if isRotating = 1 then whichMod.transform = origTransform.interpolate(finalTransform, ¬ transformPercent) transformPercent = transformPercent + 5 if transformPercent > 100 then isRotating = 0 if flippedList.count() = 2 then if _global.solveList[flippedList[1]] = ¬ _global.solveList[flippedList[2]] then matchList.add(flippedList[1]) matchList.add(flippedList[2]) flippedList = [] else isRotating = 2 whichMod = wrld.model("c" & string(flippedList[1])) whichMod2 = wrld.model("c" & string(flippedList[2])) origTransform = whichMod.transform.duplicate() finalTransform = whichMod.transform.duplicate() finalTransform.rotation.y = 180 origTransform2 = whichMod2.transform.duplicate() finalTransform2 = whichMod2.transform.duplicate() finalTransform2.rotation.y = 180 transformPercent = 0 flipPause = _system.milliseconds + 500 end if end if end if end if if isRotating = 2 then if _system.milliseconds > flipPause then whichMod.transform = origTransform.interpolate(finalTransform, ¬ transformPercent) whichMod2.transform = origTransform2.interpolate(finalTransform2, ¬ transformPercent) transformPercent = transformPercent + 5 if transformPercent > 100 then isRotating = 0 flippedList = [] end if end if end if end | 5. | Rewind and play the movie. When you flip over two cards that don't make a match, the cards now pause for half a second before flipping back. With that out of the way, let's add a timer. This will act as a scoring device, by showing how fast you complete the game. |
