We have played such a game, similar to the system, in a few lattice inside, when you pull the rocker, the number of letters constantly rolling, the last stop, if all the same or together to complete the jackpot. Below, I will show you in PPT.
① makes a black background picture, and some vertical array of alphabetic strings. As shown in the following figure, place the position, select all the alphabet strings, click the menu bar-animation-Custom animation. Eject the animation pane on the right, click Add Effect--enter--fly in.
② set the fly in property, start: Before, direction: From top, speed: fast. Then click the Small triangle button on the right side of rectangle 23 to select timing.
③ eject the Fly in dialog box, in the Timing tab, set the delay to 0.2 seconds.
④ Click on the Small triangle button on the right side of the rectangle 24 and click the timing option from the pop-up menu.
⑤ is the same as the third step, setting the delay to 0.4 seconds.
⑥, and so on, the following steps are also set to 0.6 seconds and 0.8 seconds in turn.
When Setup is complete, click the Slide Show button to see that the letters begin to appear and scroll until the 5 squares are filled in from the first grid. Show start, beginning meaning.
