The designers of Flash included editing and debugging features to make debugging easier 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

◆ 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
