How to make PPT countdown

1. Enter the title to open PowerPoint? 2003, select "Empty Presentation", select "Title Only" for the layout, enter "English Speaking Competition Timing System" in the title text box and set the font to "Bold" ". Since we need to use simple macro commands when playing slides, we need to reduce the security of macros to facilitate our use. Click "Tools/Macros/Security" and then reduce the "Security Level" to "Low". 2. Production of dynamic time display We want to realize the real-time and dynamic display of time after the timing starts. Here is the countdown (remaining time). The method to achieve this is: insert text boxes into the slide. The contents of the text boxes are numbers 1, 2, 3, etc., and then use the "appearance" effect in "Custom Animation" to animate these text boxes. An object appears 1 second after the previous object appears. In this example, because the timing time is 30 seconds, 30 text boxes should be needed, but the delay time of the first text box is 0 seconds, so we always have to insert 31 text boxes, and the first text box There is no dwell time. The contents of these text boxes are 30, 29...2, 1, 0 respectively. That is, the content of the first text box is "30" and the content of the last text box is "0". In this way, the input can be done later. To make it easier to set animations, set the alignment of all text boxes to "Horizontal Center" and "Vertical Center". Here we take setting a custom animation effect of a text box as an example to explain the steps: 1. Select the text box where you want to set a custom animation. 2. Open the menu "Slide Show/Custom Animation", and in the pop-up "Custom Animation" dialog box, we click "Add Effect/Enter/Appear" to set the animation effect of the object to "Appear". 3. In the pop-up dialog box, we click the drop-down button on the right side of the object to be set and select the "Effect Options" command. 4. After clicking the "Effect Options" command, the "Appear" dialog box will pop up. In this dialog box, we click the "Effect" tab and set the animation to "Hide after next click" or "No sound" after the animation is played. , "Send in bulk". Then select the "Timing" tab, set the start mode to "After" and the delay to "1 second". Follow the above steps to set the custom animation of all text boxes respectively: the playback mode is "appear", the effect after the animation is played: all text (except text 31) is "hide after next click", text 31 is "do not dim" ". The startup method is: all texts (except text 1) are the previous animation "after" delay is "1 second", text 1 is "click" to start, the delay is "0 seconds", the order of the text boxes is: "Text 1 ”, “Text 2” until “Text 31”. That is, "Shape 2" to "Shape 32" as shown in the figure. Finally, we insert two decorative text boxes. The input contents are "There are still more to the end" and "Seconds". The adjusted positions are shown in Figure 2. At this point, the dynamic time display part is completed. 3. Production of progress bar The progress bar can help us clearly see the time that has been used. In this example, it is displayed in the form of a percentage. The progress bar here is implemented as a rectangle. The progress bar changes every 2 seconds (that is, a rectangle appears every 2 seconds), so we need 15 rectangular blocks. Make a rectangular block in the slide and copy the others. We can control the size of the rectangle appropriately. Set the rectangle properties to: fill color "blue" and "no line", and then arrange these rectangles as shown in Figure 2. In the style shown, in order to achieve the effect of the progress bar in Figure 1, we insert a large rectangle below the progress bar, then set the fill to a darker color, and the stacking order to "bottom layer". Next, set the animation of each rectangle in the progress bar. We open the menu "Slide Show/Custom Animation" and in the pop-up "Custom Animation" dialog box, we set each rectangle separately: The animation sequence is to insert a rectangle after the two texts. , text 1 in this example corresponds to shape 2 in the custom animation, and so on. Because the first text box’s dwell time is 0, the first rectangle is behind the third text box, and the second rectangle is behind the fifth And so on, the first rectangle in this example corresponds to rectangle 33 in the custom animation, so adjust the animation order in the custom animation dialog box to "Shape 4" and then "Rectangle 33" and "Shape 6" It is "Rectangle 34" until "Rectangle 47" is below "Shape 32". The startup animation mode of all rectangles is: "Start" mode is "Before", "Delay" is 1 second; the effects of all rectangles are: "Appear", "Animation playback does not dim". Finally, we modify the progress bar again, add the indicator numbers "0, 25%, 50%, 75%, 100%" below it, and then "distribute these numbers horizontally". At this point, the progress bar part is completed.

4. Making the Button Finally, we make the "Start Timing" button, open the menu "View/Toolbar/Control Toolbox", click the "Button" tool, then drag a button on the slide, right-click the button, and open In the properties dialog box, set the "caption" attribute to "Start timing", close the dialog box, return to the slide page, double-click the button, and enter the following code in the code window that appears: Private?Sub?CommandButton1_Click() ActivePresentation.SlideShowSettings .Run SlideShowWindows(Index:=1).View.Next End?Sub Our production is all completed. Let’s check the results. Press "F5" to show the slide show, and then click the "Start Timing" button. The timing will start. The effect is as follows As shown in the figure.
