LƯU Ý An phim bên ngoài (SWF) được tải vào một cấp độ cũng được coi là một thời gian root. Trong phần "Nhắm mục tiêu Phim về trình độ," chúng tôi sẽ giải thích làm thế nào này ảnh hưởng đến kịch bản của bạn. | Targeting the Main Movie The main root movie represents the main timeline of an SWF. All of your project s other timelines exist in some way inside this one. Targeting the main timeline is simple. The syntax is _root.play You can place this script on any timeline exactly as shown and it will always cause the main timeline to play. NOTE An external movie SWF loaded into a level is also considered a root timeline. In the section Targeting Movies on Levels we ll explain how this affects your scripting. 1. Open rootTarget1.fla in the Lesson03 Assets folder. This file is identical to the one we just finished working on except that two buttons appear on the lower-right portion of the stage. We will script these buttons to resize the main timeline when they are clicked. We will then copy these buttons place them inside our movie clip instances and without modifying the target paths used in the script demonstrate how you can use _root to target the main timeline apart from any other timeline in the SWF. 2. With the Actions panel open select the button with the minus sign over it and add the script 3. 4. on release 5. 6. _root._xscale _root._xscale - 10 7. 8. _root._yscale _root._yscale - 10 9. 10. 11. When this button is pressed and released the main timeline s size will be reduced by 10 percent. Because the button to which we re attaching this action resides on the main timeline which is also the timeline affected by the button this script doesn t require a target path. We use an absolute target path here to demonstrate its universal effectiveness. 3. With the Actions panel open select the button with the plus sign over it and add the script 4. 5. on release 6. 7. _root._xscale _root._xscale 10 8. 9. _root._yscale _root._yscale 10 10. 11. 12. This script is similar to the one in Step 2 except that when this button is pressed and released the main timeline s size will increase by 10 percent. 4. Drag-select both buttons and the text on top of the buttons and copy them. .
