You can quickly set and remove breakpoints to check different parts of your code to determine if it’s working correctly. Flash uses a different debugger for ActionScript 3.0 files (FLA or AS) than it does for ActionScript 2.0 files. The functionality is similar, but the look and feel is different. The debugger for ActionScript 3.0 uses the Debug workspace that displays the Debug Console, Variables, and Output panels along with the Actions panel or Script window. The Debug Console displays the call stack, scripts containing the functions in the call stack, and contains buttons to step through the code. The call stack shows the current list of nested function calls ready for exe- cution. The Variables panel displays variables and their current values. When a problem is encountered, Flash displays the line of code in the Compiler Errors panel. Double-click the error to view it in the code. Debugging for ActionScript 3.0 Use the Debugger for ActionScript 3.0 Create or open a Flash document (ActionScript 3.0). ◆ To debug an ActionScript 3.0 file (AS), open the file in the Script window, select the associated Flash file from the Target menu. Click the Debug menu, point to Debug Movie, and then click Debug. ◆ You can access debugging commands on the Debug menu. Add or remove breakpoints to interrupt the execution of the scripting code. ◆ Add. Click in the left margin next to the line of code. ◆ Remove. Click the breakpoint in the left margin. To step through the code line by line or step in and out of functions, use any of the following: ◆ Step into code line by line. Click the Step In button in the Debug Console panel. ◆ Step over a function call. Click the Step Over button in the Debug Console panel. 4 3 2 1 3 4 Output panel Actions panel 2 1 From the Library of Wow! eBook ptg Chapter 17 Debugging a Movie 417 ◆ Step out of a function call. Click the Step Out button in the Debug Console panel. ◆ Resume normal code execution. Click the Continue button in the Debug Console panel.

In the Compiler Errors panel, you can show or hide warnings or errors ( New! ), scroll through each one ( New! ), and display/highlight them in the code ( New! ). You can also manage the types of compiler warning that appear in the Compiler Errors panel by setting options in the Publish Settings dialog box. Two options are available: Strict Mode and Warnings Mode. Strict Mode reports warnings as errors, while Warnings Mode reports extra warnings for discovering incompatibili- ties when updating ActionScript 2.0 code to ActionScript 3.0. 418 Chapter 17 Resolving Compiler Errors Resolve Compiler Errors Create or open a Flash document (ActionScript 3.0).
